    "verified_text": "whilst peace is largely an economic and political struggle between men whose purpose is to gain physical and individual security, war is largely a physical struggle between nations in which the acquisition or maintenance of economic and political security is the aim. in peace man uses his physical force to conquer nature; in war he uses it to conquer his own kind. in the one case the conflict is mainly a material one, in the other it is largely ethical, as it is directed against opinion sustained by force and not against matter merely en- dowed with energy. relationship of peace and war.—tin peace the ethical rights of nations are maintained by force actual or potential according to the political system in vogue; for even in the most democratic nations the power of the majority expressed tn the legislative, police and military forces of the nation is the foundation and guardian of the national will. in peace as in war the final arbiter of law and order is military force. the means differ in degree though the end is the same. the end is ihe maintenance of in- ternal existence, in the one case through prevention of internal disruption, and in the other through the prevention of external pressure. it is for this reason that william james, when discus- sing ““the moral equivalent of war,’ was of opinion that: “every up-to-date dictionary should say that ‘ peace’ and ‘war’ mean the same thing, now i posse, now in actu. it may even reasonably be said that the intensely sharp competitive preparation for war by the nation is the real war, permanent, unceasing; and that battles are only a sort of public verification of mastery gained during the ‘ peace’ intervals.” and clause- witz— that war is nothing but a continuation of political inter- course, with a mixture of other means.” and again: “ we see, therefore, that war is not merely a political act, but also a real political instrument, a continuation of political commerce, a carrying out of the same by other means . . . for the political view is the object, war is the means, and the means must always include the object in our conception. . . . state policy is the womb in which war is developed, in which its outlines lie hidden in a rudimentary state, like the qualities of living creatures in their germs.” if in peace force is essential to the maintenance of tranquillity, prosperity and the security of the social order: in war (the causes of which may always be traced to some discontent in the existing state of peacefulness), the true political object is to create a better condition of peace than that which existed before its out- break. this condition is in nature three-fold—in order that the war may have proved itself economical, then must the peace which follows it be more contented, prosperous and secure than the one the war destroyed. in great civilised nations this de- struction of the conditions of peacefulness—rather than of the material power of the enemy or of the enemy himself, is accom- plished by military pressure and resistance as exerted by the instrument of war, which may be an army, a navy or an air force, or all three combined. to animate this instrument the will of the majority of the nation must support the war; for in democratic countries it is this will, as expressed by the government, which makes war, accepts defeat or insists on victory. further, to maintain the fighting forces which express the national! will through physical action, the economic strength of the nation must be sufficient to provide them with all material needs, and never more so than to-day when the rapid mechanicalisation of the means of waging war is bringing all three services into intimate relationship with civil industry, and through civil industry with each other. the co-ordination of all these means—the will, economic strength and fighting force of the nation—toward the attainment of the political object of the war may be termed grand strategy, or the major movements and higher leadership which control, direct and influence the war. 655 grand strategists of historyy—there is nothing novel in this conception, for as a foundation of military action the co-ordina- tion of political direction and military control are as old as or- ganised warfare itself. but whilst duting the earlier history of war co-ordination was less complex since armies were more inde- pendent and self-supporting, in modern wars its importance has become more and more manifest until its establishment on a scientific footing may be considered one of the most important of military problems. for co-ordination to exist, united control of all the forces expended in war as well as liberty of action in their expenditure are essentials. in democratic nations the first should be the prerogative of government, and the second of military command. in the world war of 1914-8 a lack of strategical direction, especially on the side of the allied powers, was manifested on its outbreak, and was never overcome; for though towards the end of the war marshal foch was appointed generalissimo of the land forces of the allies, no true political unity of control was created or could have been created in the circumstances. fail- ing the establishment of a despotism, which is almost unthink- able among allied democratic powers, this weakness in political control must always constitute the achilles heel of nations tem- porarily confeidlerated to resist the military pressure of a common enemy. in this war we find the allied grand strategy far more rudimentary than that of alexander the great. he, as tyrant of the grecian states, combined in his own person complete political control and unity of command. the grand strategy which he developed stands as a model for all times. he saw that the states and cities of greece could only be con- trolled by outward pressure, and that this pressure could only be gained through the conquest of the persian empire. his method was logical and scientific. first, he established tran- quillity at home, without which his overseas expedition would have had no secure base from which to operate. secondly, he gained command of the sea, and through this command control of the economic resources of egypt, which were vital to the prosperity of greece. thirdly, he gained command of the land, and by ascending the throne of the great king was able to con- trol not only the military resources of persia but also its immense wealth. lastly, he attempted to bound his vast empire by un- attackable frontiers so that it would be secured against invasion, his crucial .idea was the establishment of a more contented, prosperous and secure peace. in the world war of 1914-8 we see no such grand strategy, because unity of political control was non-existent, and failing this unity true liberty of military action was impossible. throughout the entire history of war the most successful of the great captains, such men as alexander, caesar, gustavus, frederick and napoleon, have been despots or autocrats, not because despotism and autocracy are in themsclves military virtues, but because they permit of the closest political contral of the strategy of a war. to-day the difficulties incumbent in grand strategical control are increasing, for whilst in the past military power mainly depended on man-power, which enabled all armies to establish a similar organisation and tactics, industry and industrial wealth are replacing population as the foundation of military strength. this amongst allied powers will frequently mean a divergence in military organisation, a variation of tactics, and consequently an increasing difficulty in control and combined action. problems of grand strategy — though there can be no doubt that the establishment of a more contented, prosperous and secure state of peacefulness is the true grand strategical object of a war, it by no means follows that this has generally been accepted; in fact few wars have led to so desirable a conclusion. the reason for this is twofold. first, no nation has hitherto possessed the grand strategical machinery necessary to co-or- dinate political thought and military action, consequently war- fare has assumed an almost entirely military aspect. secondly, the causes of war have never been scientifically analysed, and have been obscured and hidden beneath the political pretexts and excuses justifying its outbreak, 656 as these justifications are seldom rational or true, a great war has normally been declared when through political obscurantism the mind of a nation is in an irrational mood. the nation is stirred up to fury, and the soldier, stimulated by this national emotion accentuated by the dangers which surround him, seeks a solution to the war in a victory of destruction. he attempts to impose on his enemy not so much his will as his physical force, and the result in the world war of 1914-8 was that the victors suffered but little less than the vanquished. this system of ‘* absolute warfare,’”’? much lauded by clausewitz, and founded on the ideal of absolute government, has toned the whole course of warfare since his day. the solitary exception was the cam- paign of 1866, in which moltke’s object was not to destroy aus- tria, but to gain her over as an eventual ally. as long as this barbarous system of grand strategy endures great wars will be concluded by vindictive peace treaties out of which further great wars will evolve. no modification or reduction of arma- ments can ameliorate this system, for its betterment must be sought in a change in the political brain—in the theory of war, and not in its tools. granted a political organisation which can co-ordinate, con- trol and direct the forces of war, the next problem in grand strat- egy is the co-ordination, control and direction of the means. hitherto military means have been mainly considered, but dur- ing the world war it became apparent that economic and ethical action played as important a part. to compel an enemy to accept defeat his national will must be broken. the traditional method has been to destroy the enemy’s armed forces—the shield which protects this will. though during the world war this method was universally adopted, as the war proceeded, the economic attack by blockade, bunker control and unrestricted submarine warfare, and the ethical attack by insidious propa- ganda became formidable instruments in undermining the na- tional morale of the belligerenis. in the case of germany and her allies these means led to their defeat as much as did military pressure, because they directly attacked the national will to win. the co-ordination, control and direction of the fighting forces themselves is the next problem, and here grand strategy merges into grand tactics, and policy into plan. in the case of great britain there was no grand tactical control during the world war, because no organisation existed which could co-ordinate naval and military force or action. the result of this was that directly power of movement ceased on the western front, com- mand of the sea at once suggested, as it had done during the napoleonic wars, a change of the theatre without reference to the grand tactical objective, which remained the defeat of ger- many. this lack of grand tactical co-ordination undoubtedly prolonged the war for many months. once given a political organ which can formulate policy, and a military brain which can produce a co-ordinated plan in which the fighting forces are considered as one force, the next problem is the execution of the plan. this demands expenditure of force, and here grand strategy and grand tactics merge into strategy and tactics as these are generally understood. expenditure of military force —expenditure of military force is an art, and like all other arts it is based on science. the science of war is the science of human conflict in all its forms, whether the battle is a fight between two men or two or more nations. without this science warfare must largely remain in an alchem- ical state, and be governed by chance and not by law. if force has to be expended ijn war, then the side which can best econo- mise its force is the side which is more likely to win. economy of force is, therefore, the governing law of war. granted this law the next question is to decide on the nature of force; and as an army is but a number of men, the forces of war are to be sought in man himself. human force is threefold in nature, it is mental, moral and physical, and no one of these forces can be expended without influencing the remaining two. economy in the expen- diture of these constitutes the central problem of strategy and tactics. the expenditure of force presupposes pressure and resistance, and these two govern the direction force eventually takes. in strategy war each side must have an object which provisionally fixes the direction of military operations. to maintain this direction pressure and resistance must be exerted. these two factors if correctly employed lead to an economical distribution of force from which concentration of force may be developed. thus are obtained three principles of war, namely, the principles of the direction, distribution and concentration of force, and these should control the formulation of all plans of war. these three principles are, consequently, closely related 1o the mental sphere of force—to the thoughts in the head of the general-in-chief out of which he evolves his plan. before this plan can be transformed into physical action, that is executed by the men themselves, the troops must not only be willing but determined to carry it out. to do so their morale must balance their fear, consequently their determination to act must be supported by moral endur- ance. further, to economise this endurance, they should aim at surprising the enemy, that is demoralising him. in the moral sphere of war we thus obtain three principles closely related to the former ones. they may be called the prin- ciples of the determination, endurance and demoralisation of force. it isin this moral sphere that the decisive battle is waged. to attack the enemy’s determination to win, physical action must be brought into play. men must move, and movement depends on how far offensive action can be protected. thus are obtained three physical principles of war, namely, those of mo- bility, security and the disorganisation of force (offensive action). nine principles of war, therefore, govern the expenditure of force. three are related to pressure, three to resistance and three to the control of their resultant—the direction of the oper- ation, the determination of all ranks to attain the object in view, and movement towards the objective itself. these nine principles, which are expressions of the law of economy of force, form the foundations of the science of war, without which the art of war is solely determined by individual predilection or chance. this science is expressed as an art through the instrument of war, the military organisation at the command of the general-in-chief, who, to act rightly, expends its force by applying the principles of war according to the ever-changing conditions which surround him. these conditions can either assist or resist him, and by a correct, that is, an economical apph- cation of principles to conditions, he abstracts the highest assist- ance from all the forces which surround his army. for him to do so with true economy it is necessary that the organisation of his army should be suitable to the nature of the operation in hand. this suitability consists in power to develop protected offensive action in the shortest possible time and at the highest possible speed. from these considerations we see that not only are strategy and tactics complementary halves of the art of war, but that the geometric strategical ideas so favoured in former days, such as interior and exterior lines, lines of operation, concentric and eccentric attacks, etc. etc., are but details of the art of war, which should be as ‘ fluid” as any other art, and is so when it is based on a full understanding of the science of war instead of on a personal improvisation. all that is necessary to prove the close inter-dependence of strategy and tactics is to turn to the history of war and examine its course. history of tuctics—the tactics of the roman legion were based on the strategical mobility which their magnificent roads allowed. this mobility could only be maintained as long as troops were concentrated in large bodies. once defensive tactics led to an over-distribution of force, through the establishment of a cordon system along the frontiers, the gothic horse rapidly overruns the empire, and after the battle of adrianople (378) an infantry decline sets in. thence onwards, except in moun- tainous and swampy countries, infantry degenerate into camp followers. as the roman roads fall into disrepair the use of cavalry becomes general; further, all nomadic warriors are horsemen. influence of the horse.—the influence of the horse on tactics is profound, and through tactical change strategy and organisa- {ion are modified, and the first post-classical cycle of war is stratford-on-avon—stresemann entered. the superior carrying power of the horse at once sug- gests the general use of armour from which to develop the offen- sive power of the soldier. the armoured horseman changes the whole organisation of war. armies grow smaller since armour is expensive; casualties amongst armoured horsemen grow less and less, and the strength of a nation depends more on its ability to produce armour than on its man-power. two defects are, however, never overcome, the first is the armouring of the horse, the second the difficulty of an armoured man using missile weapons when mounted. strategy, save as stratagems, disap- pears; the tactical shock becoming the sole purpose of battle. this condition of war lasts for 1,000 years, when the long bow and pike attack the unarmoured parts of the horse, and gun- powder attacks armour itself. the result is the reappearance of infantry. by the date of the battle of agincourt (1415) the mobility of the armoured horseman is reduced to zero. the second tactical cycle is now entered. protection by ar- mour is by degrees replaced by protection through fire power, from which the shock of the pike-men is developed. as the mus- ket, and later on the bayonet, are comparatively cheap weapons, armies grow in size, numbers of men rather than skill become the aim of the military organiser; roads grow in importance to maintain these masses, and casualties increase as fire power is developed; ultimately we enter the period of absolute warfare. the introduction of railways and steam power generally is fol- lowed by an enormous increase in the size of armies and in the perfection of weapons and equipment. hordes of men are poured on to the battlefield, their control is difficult, their supply even more so, and, as fire power increases, the protective power of firearms is supplemented by the trench, and strategy vanishes through a general inability to move. by the year 1915 the zero point of movement through rifle and gun power is reached. as the second cycle was introduced by the discovery of gun- powder, the third is introduced by the discovery of petrol. the first tactical cycle, based on armour, was protective in nature; the second, based on gunpowder, was offensive; and the third which has now begun is based on petrol, and its predominant quality will be mobility. in the world war the transition be- came apparent when a solution to static warfare was sought in prolonged artillery bombardments. the railways could amass thousands of tons of shells at the railheads, but from these points forward hurdreds of lorries had to be used to move them. the shell failed to solve the problem of mobility, since in destroying the enemy’s defences it simultaneously destroyed the surface of the ground, rendering it unfit for wheeled traffic. eventually the tank solves the problem, as it can dispense with roads and move across country. this power, the ability of developing offensive action from protected cross-country movement coupled with the power of aircraft to attack an army in rear without engaging its front definitely ushers in the third tactical cycle which must profoundly influence strategy. the passing of linear warfare.—from the days of the ro- mans to present times the network upon which strategy was woven has been the road systems existing at any specific date. armies advanced and retired along roads, their power of manoeu- vre being largely limited by their number and condition. from road columns they deployed into battle lines, and in classical times line met line in a hand to hand struggle. after the intro- duction of firearms, a space, or no-man’s-land, was developed between the contending forces, possessing in the days of ired- erick the great a depth of some so paces. this space profoundly influenced tactics, for the side which could make the better fighting use of it generally won. to take advantage of this area weapons were improved, and accuracy, range and volume of fire increased, until in the world war its depth extended over 1,000 paces. gas as a weapon was then introduced to obliterate whatever human resistance existed in or on the other side of this space, and eventually tanks were built to cross it and pass threugh the hostile battle-front and attack the enemy’s rear organisation and _ services. aircraft could do likewise by passing over in place of, through or round the enemy’s line. the line had, in fact, reached its zenith, and 657 was no longer an economical formation, since it could not guar- antee the protection of the area in rear of it. the influence of these tactical changes must pronouncedly modify strategy, as linear warfare will be replaced by area warfare, the strategy of which being to a large extent independent of roads and railways will become two and three dimensional. these changes in the art of war face all civilised armies to-day, and it is for this reason that a science of war is necessary, so that the past history of war may be methodically analysed, and future tactical, administrative and strategical tendencies predicted. without such a science, supported by sound political control, strategy must remain, as it has in the past, either the perquisite of genius or the plavthing of chance. see war. (j.f.c.f.) stratford-on-avon, england (see 25.998), had a popula- tion of 9,392 in 1921 and an area of 4,013 acres. a summer season of the shakespeare festivals, which have been under the control of mr. bridges adams since sir frank benson’s resig- nation in to19, has been held since rg10. nash’s house was adapted for public use in 1912. in march 1926 the shakespeare memorial theatre was destroyed by fire; but the library and museum, in adjacent buildings, were saved. a water supply scheme, by gravitation from a reservoir at snitterfield, was completed in 1923. strathcona and mount royal, donald alexander smith, 1st baron (1820-1914), canadian statesman (see 25.1000), died in london jan. 21 1914. his barony passed by special remainder to his daughter margaret charlotte, wife of robert jared bliss howard of montreal (d. 1921). strauss, richard (1864- ), german composer (see 25.1003). his opera, ariadne auf naxos (1912), was produced at his majesty’s theatre, london, by thomas beecham in may 1913 and the same year der rosenkavalicr, first produced at dresden in 1910, was performed at covent garden with great success, eight performances being given; in point of fact, this proved to be strauss’s most popular opera. his other works in- clude festliches praeludium, for orchestra (1913), and josephs legende (i914). in addition to the works enumerated, mention should be made of kine alpensinfonie, (1915, op. 64); and the three-act opera, die frau ohne schatten, libretto by hugo von hofmannsthal (1916, op. 65). in the winter of 1920-1 strauss visited south america, where he officiated at buenos aires as opera conductor, subsequently returning to vienna. stravinsky, igor fedorovich (:882- ), russian composer, was born at orantenbaum, near leningrad, on june 5 (old style) 1882. he began to study composition privately under rimsky-korsakov in 1902 and four years later produced his first work, a symphony. this was followed in 1908 by a fantastic scherso, the dirge in memory of rimsky-korsakov and the orches- tral tone-picture, fireworks. much of his subsequent music was composed for serge diaghilev’s russian ballet, and includes te fire bird (1910), petroushka (1912), and the rite of spring (1913). stravinsky’s music aroused a great deal of controversy, chiefly owing to a peculiar originality of structure which im- pressed his audience by the sense of surprising novelty which it conveyed. among his later works are renard (19015), l’ histoire du soldat (1917), the symphony for wind instruments to the memory of claude debussy (1920), afatra (1921) and les noces villageoises (1923). street: see road construction. street traffic: see traffic problems. stresemann, gustav (1878- ), german statesman, was born in berlin may ro 1878 and studied political economy in berlin and leipzig. after completing his studies he went on the management of an industrial association, and in 1903 became secretary to the bezirksvereins des bundes der indusiriellen (district association of the league of industrials) in dresden. hfe soon succeeded in organising the sechsischen landesver- band des bunudes der industriellen (saxon provincial union of the league of industrials) out of the different district organisa- tions. thanks to his far-reaching organising activity strese- mann secured a prominent position for these associations in the economic and political life of saxony. the union in 1925 658 numbered about 7,000 industrial undertakings with some 600,000 workmen. stresemann’s excellent organising successes brought him more and more influence in the headquarters of the union of industrials in berlin. provincial unions were founded on the saxon model in wiirttemberg, silesia and thiiringia, strese- mann playing a prominent part. in the further course of his activity in the field of political economy, he was founder and first president of the german-canadian and the german- austrian-hungarian economic association (wirtschaftsver- band) and vice-president of the german-bulgarian league in berlin. he was also prominent in the organisation of the german fleet league (flottenverein). in ror3 stresemann and rallin, the general manager of the hamburg-america line, founded the german-american economic association, which was destined to be expanded into a german world commercial association, a plan prevented by the out- break of the world war. in 1907 stresemann had been elected to the reichstag as member of the national liberal party, where he often spoke for his party on questions of public economy and foreign policy, and enjoyed increasing respect. he soon became a member of the central executive of the party, and bassermann, recognising his great talent as an organiser and speaker, trained him, so to speak, as his successor. during the war stresemann pursued a vigourous nationalist policy, and was one of those who brought about bethmann hollweg’s fall. after the collapse he founded the german people’s party (deutsche volkspartei), becoming its president, having been, after bassermann’s death, president of the national liberal party. . the german people’s party, led by stresemann, played a decisive part in germany’s internal policy after the war. it was opposed to the weimar constitution; on principle it re- mained long in opposition to the governments of the left. when the ruhr conflict reached its climax, stresemann published a series of articles which attracted much attention, urging a radical change in german policy; after the fall of cuno’s cabinet, in germany’s darkest hour, he became chancellor of the reich with a ministry of the so-called ‘‘ great coalition,” including all parties from the social democrats to the german people’s party. as chancellor, he wound up the ruhr conilict. after a bare two months the social democrats abandoned him because he had had to take strong measures in the name of the reich against the manifestations of bolshevism in saxony and thur- ingia. he formed, however, a second cabinet, which lasted till the end of nov. 1923. in marx’s cabinet, which followed his own, stresemann became foreign minister. his was the guiding influence on the foreign policy of this cabinet. he was largely instrumental in bringing about the acceptance of the dawes plan by germany and the conference of london in aug. 1924. after marx’s resignation he refused to form a new cabinet, and used his influence to get the german nationalist party included in the government. he felt the valuable economic forces of this great party should not be condemned to eternal fruitless opposi- tion. he himself remained foreign minister in luther’s first and second cabinets. during the long governmental crisis he sent the famous feb. memorandum of 1925 to the entente, which laid the foundations of the pact of locarno. throughout 1925 this policy initiated by stresemann was the focus of interest, not mercly of germany, but of the whole world. the conference of locarno brought success. on dec. 1. 1925 the pact of locarno was solemnly signed in london. a man with many bitter enemies as well as sincere admirers, it must be agreed that stresemann carried out a consistent policy without regard to party hostility. he can thus claim the merit for having freed the ruhr district and the first rhineland zone from foreign military occupation, for having laid the political foundations for the stabilisation of the currency and for having brought about less strained political relations between germany and the outer world. one of the best speakers in germany, he also possesses great political ability and practical streuvels—strikes and lockouts common sense. he wrote on the pact of locarno for this excy- elopedia. (if. kle.) streuvels, styn (1871- ), pen name of frank lateur, flemish writer, was the nephew of the priest-poet guido gertelle. for a long time he worked as a pastry cook at avelghem in flanders and then settled down at ingoyghen, close by, in order to devote himself entirely to literature. essentially a man of the soil, he nevertheless possessed a clelicate artistic sensibility and acquired considerable literary culture. he is the most popular contemporary writer in flanders and enjoys a great reputation throughout holland, although he frequently introduces the western flemish dialect into his writings. many of his novels have been translated into german. his descriptions of the coun- trvside, no less realistic than poctical, are presented with enor- mous vigour and pungency in a style which seems to echo the rhythms of nature herself. de vlaschaard (1907) is considered his best work. strikes and lockouts (sce 25.1024).—the period under review has been characterised in all industrialised countries by an endemic condition of industrial warfare. despite all the machinery of conciliation and the immense amount of both voluntary and legislative effort to secure the peaceful and equit- able settlement of disputes between employers and workers, the organic development of the economic system is. continually being interrupted by trials of strength which bring widespread distress both to those directly involved and to the rest of the community. the following article is confined to a statistical statement and description of the principal strikes and lockouts which have occurred between 1907 and 1924. for a discussion of the broader questions involved see industrial relations and trade unions. i. great britain and northern ireland the following table brings together the gencral totals for the strikes and lockouts which have occurred in cach year under review in great britain and northern ireland.' aggregate duration in number of | total num- working y disputes ber of days of all =a beginning | workpeople | disputes in in year involved progress during the year 1907 585 146,000 2,150,000 1908 389 293,000 10,790,000 1909 422 297,000 2,690,000 i9io 521 514,000 9,870,000 iqii 872 952,000 10,160,000 i9t2. ;

that is to say, to less than the effect of a single public holiday, an almost insignificant loss by comparison (for example) with the loss through sickness or through involuntary unemployment. the statistics relating to the causes or objects of disputes show that wages questions account for about two-thirds of the total num- ber of strikes and lockouts. in years of good or improving trade, such disputes largely arise out of demands for advances in wages; and it is worth noting, in this connection, that no important disputes arising out of resistance to a reduction in wages occurred’ between 1908 and the end of 1920. disputes arising out of questions of hours of labour were unusually frequent in 1919, when the movement towards shorter hours was at its height: 10% of all the disputes of that year were due to questions of hours. in other years the propor- tion averages less than 3°, of the total number. disputes arising on questions of particular classes or persons (¢.g., demarcation dis- putes, strikes for the removal of an unpopular foreman or for the reinstatement of a dismissed fellow-worker) account for about 15%; and other disputes (largely concerned with questions of trade union principle) for a similar proportion of the total. of all the disputes, about 25% ended definitely in favour of the workpcople, about 30% in favour of the employers, and about 45 % were compromised. even this large figure, however, docs not fully represent the predominance of compromised settlements, because the tendency to settlement by compromise is greatest in the case of the larger disputes; hence of all the workpeople directly involved in strikes and lockouts about 65 °% resumed work after a compromised result, while about 20% resumed after a settlement definitely in their favour and about 15° sustained defeat. the great majority of the disputes—bet ween two-thirds and three- quarters of the total—were settled by direct negotiation between the parties or their representatives, and one-half of the remainder by conciliation or by arbitration, other methods by which strikes and lockouts have been terminated in recent years have included unconditional surrender of the workpeople, the closing of works and the replacement of workpeople. during the war years a number of disputes were terminated by administrative decisions of the government. one of the greatest disputes, viz.: that in the coal- mining industry in 1912, was settled by the enactment of the coal mines (minimum wage) act. particulars of industrial disputes in great britain will be found in the official abstract of labour statistics and in the monthly ministry of labour gazetie; the issue of the labour gazette for july 1925, contains a review of the disputes of the 15 years 1910-24, and that for jan. of each year, which contains a review of the disputes of the previous year. principal disputes in the united kingdom.—lt has already been pointed out that a very small minority of the disputes account for by far the greater number of workpeople involved and of days lost; two or three big disputes, indeed, commonly account for an altogether disproportionate share of the days lost in any year. the most remarkable example of this occurred in 1921, as will be seen from the following figures:— workpeople | man-days involved lost one coal-mining dispute . 1,150,000 72,000,000 one cotton dispute 375,000 6,750,000 761 other disputes . . 276,000 7,120,000 total 1,801,000 85,870,000 on the other hand, in some years there were no disputes of outstanding importance; the years 1907 and 1gog are examples, though it will be observed that both these years had more industrial disturbance, so far as mere number of disputes goes, than the intervening year, 1908. bricf comments are appended on some important disputes. the cotton strike of 1908 is memorable as having been, with two other disputes of the same year, the last important dispute, for the 659 long space of 12 years, arising out of resistance to a reduction in wages in that trade. the seamen’s and transport workers’ strike in 1911 began with the seamen striking in support of a demand for a conciliation board. dock labourers and other transport workers joined in the strike, partly in sympathy with the seamen and partly in support of their own demands for improved conditions. there was a good deal of dissatisfaction with the working of the agreements reached in settlement of these disputes, and further strikes occurred in the following year, particularly on the thames and medway. the rail- waymen in ig1t struck for an improvement in the railway con- ciiation board scheme, which had been sct up in 1907. the cotton dispute of 1911-2 began with strikes of weavers in lancashire against the employment of non-unionists, to which the employers replied by a general lockout. the coal strike of 1912 arose out of a demand by the miners’ federation for the payment of an individual district minimum wage for all underground workers in mines, irrespective of the question whether the men's working places were abnormal or not. the dispute was settled by the passing of the coal mines (minimum wage) act 1912, which provided for the setting up of joint district boards to determine the minimum rates of wages of underground workers in coal-mines. the world war, as will be seen, by no means put an end to strikes; but most of them were small, and were speedily brought to an end. iience the aggregate duration was brought down to a very low point in 1915 and 1916. ‘there were, however, several unauthorisechstrikes in the engincering and munition trades in 1917, which caused great concern at the time, though only one was of very serious importance as measured by aggregate duration. it was in these disputes that “shop stewards ”’ (sometimes acting in defiance of their own trade- union executives) first came prominently into public notice. there were many industrial disputes in 1918, but the great major- ity involved small numbers and were of short duration. in i91g and 1920, on the other hand, there were many serious disputes. a great railway strike occurred in sept. and oct. 1919, the national union of railwaymen being dissatisfied with the new standard rates pro- posed for certain grades. there was also a prolonged ironmoulders’ strike, which lasted for four months, and seriously dislocated the engineering industry. in the same year there was a great strike in the cotton trade, both the spinning and the weaving branches being affected. the operatives asked for a reduction in hours and an advance of 30° on list prices. the advance was granted, and the hours reduced to 48 per week (instead of 463, as asked). the principal dispute of 1920 and again of 1921 was a national strike in the coal-mining industry (see coal). the cotton dispute of 1921 arase out of a demand of the employers for a reduction of 95°% on the standard lists of wages (equivalent to about 30° on the rates then actually being paid). this was reduced to 80° during the subsequent negotiations. the dispute was finally settled by the operatives accepting a reduction of 70% (60% at once, and another 10% after six months). the engineering dispute of 1922 arose out of the rejection by the members of the amalgamated engineering union, on a ballot vote, of a provisional agreement on overtime and the exercise of managerial functions which had been reached between the executive of the union and the engineering and the national employers’ federations in nov. 1921. the members of the union were, therefore, locked out on march 11; and members of other unions employed in federated enginecring shops were also locked out on the following may 2. on may 17 the employers put forward new proposals, embodying the principle of prior consultation with the workpeople when a proposed change involved the displacement of one class of workpeople by another. these terms were eventually accepted by all the unions concerned, and work was resumed at various dates in june. the shipbuilding dispute of the same year arose out of a proposed reduc- tion of wages; a modified reduction was accepted after a stoppage of six weeks. the shipbuilding dispute of 1923 was confined to the united society of boilermakers and iron and stecl shipbuilders, which refused to accept an agreement with the shipbuilding employers’ federation relating to overtime and night-shift working, which had been signed by the other shipyard unions. the lockout was settled, after a stoppage of nearly seven months, by the federation agreeing to reconsider, in consultation with the boilermakers’ society, five points which were alleged to need correction or adjustment in their application to the members of the socicty. the general strike of 1926 the great coal dispute of 1921 was terminated (see coal) by the signing of an agreement between the miners and the mine- owners, providing for the automatic regulation of wages from one period to another on the basis of the ascertained costs of production, proceeds, etc., in an earlier period. in jan. 1924 the miners’ federation gave three months’ notice to the mining association to terminate the agreement of r921. in june 1924, after prolonged negotiations, a new agreement was made, which 660 was, in the main, much more favourable to the men than the agreement of ro21, though it contained some provisions intended to benefit the owners. unfortunately, not long after the new agreement came into force the industry entered upon a period of very severe de- pression; and the agreement, therefore, with its improved terms to the miners, proved extremely onerous to the owners. on june 30 1925 the owners gave the miners one month’s notice to ter- minate the agreement; and on the following day they com- municated to the miners their proposals for a new agreement, which were rejected by a delegate conference of the miners’ federation. on july 30 the prime minister offered financial assistance to the industry until april 30 1926, to allow time for a full investigation to be made; and on the following day (the day when the owners’ notices to the men would otherwise have expired) the terms were accepted, and arrangements were made for work to be continued. the total cost of the subvention, from the beginning of aug. 1925 to the end of april 1926, was £ 24,000,000. the samuel report-—on sept. 5 1925 a royal commission was appointed, under the chairmanship of sir herbert samuel, “ to enquife into and report upon the economic position of the coal industry and the conditions affecting it, and to make any recom- mendation for the improvement thereof.” the royal commission issued its report on march 6 1926, suggesting a number of measures that might be taken for the improvement of the in- dustry, but also expressing the opinion that an immediate re- duction of working costs, by means of a revision downwards of the minimum percentage addition to standard rates of wages, was essential, as a temporary measurc, to save the industry. they considered it essential’ that, though national wage agrce- ments should continue, there should nevertheless be, as hitherto, considerable variation in the rates of wages in the several dis- tricts, and laid it down that, ‘‘ before any sacrifices are asked from those engaged in the industry, it shall be definitely agreed between them that all practicable mcans for improving its organisation and increasing its efficiency should be adopted.” the report was accepted by the government in its entirety, but only subject to acceptance by the other two parties. the owners issucd a statement expressing gencral agreement with the report; but they at first desired to initiate negotiations with the miners on district lines. later, under pressure from the government, they withdrew from this position; but the best terms which they were able to offer represented a severe reduc- tion of wages in most districts; and, owing to the delay already mentioned, these terms were not presented to the miners, na- tionally, until the owners’ notices were on the point of expiring. the miners were strongly averse to any reduction of wages or any increase of hours; they also wanted assurances that were not forthcoming as to the measurcs of reorganisation mentioned in the paragraph quoted textually above. no scttlement was found possible; and the owners’ notices, which they had issued in anticipation of the termination of the subsidy period on april 30, took effect on that date. a general sirike called.—mcanwhile, the general council of the trades union congress, who had already come to the assist- ance of the miners in july 1925—the miners’ federation had ‘“nlaced their case unreservedly in the hands of the gencral council’ at that time—again intervened; and prolonged nego- tiations followed. on may 1 1926, with a view to assisting the miners, the general council issued instructions calling out on strike the railway and transport workers, the printing and paper trade unions, some branches of the metal and enginccring and of the building trade workers, and some other classes; and it was intimated that other classes of workers would be called out later, if necessary. this was the first example of a general strike in great britain, though there had been a strike of this kind in dublin in 1913, involving about 20,000 workpeople. the stoppage on the railways and at the docks, of tramway and omnibus services, and of printing, was at first nearly com- plete; though there was some recovery as the strike went on. volunteers, and men who had refused to come out or had gone strikes and lockouts back to work, maintained or restored a skeleton service on the railways and omnibus routes, and on some of the provincial tramways; some work was also done by volunteers at the docks. apart from this, the government were able to introduce an emergency service of motor transport, sufficient to censure a supply of necessary foodstuffs; and many thousands of volunteers offered themselves for work in all sorts of capacities, and as special constables. strict orders were issued by the trade unions to their members to refrain from provocation, and cases of serious disorder or violence were rare. the success of these measures, together with a judgment given by mr. justice astbury declaring the general strike to be illegal and not covered by the protection of the trade disputes act, and pronouncements in the house of commons to the same effect, no doubt hastened the termination of the strike. the gencral council had also been in touch with sir herbert samuel, who had been acting, unoflicially, as a mediator, and had agreed with him on a formula which, it was hoped, would enable negotiations to be resumed. in this hope the general council informed the prime minister on may 12 that they had decided to call off the strike unconditionally. sir herbert samucl’s formula was not, however, accepted by the miners; nor was it adopted by the government, who, on the termination of the general strike, immediately re- sumed negotiations with the miners. some difficulties arose in connection with the resumption of work after the general strike. the most important source of dis- location, at least on the railways, arose from the fact that, partly owing to the lack of coal traffic and the necessity of economising coal, a great reduction in the railway services was in any case inevitable, and it was, therefore, impossible to re-employ im- mediately all those who had gone on strike. on may 14, however, the railway companies came to an agreement with the three railway trade unions, on the basis of undertaking to take back the men as work could be found for them; the trade unions also acknowledged that they had been guilty of a “‘ wrongful act ”’ in bringing their members out on strike without the usual notice. similar agreements were made with the other trade unions. the strike of the miners, however, still continued. if, foreign countries a brief account is given below of strikes and lockouts in the years after the war in the principal european countries, other than great britain, from the ollicial statistics available at the beginning of 1926:— | belgium.—the average annual number of labour disputes in the post-war years (1920-4) in belgium was 261, directly affecting an average of 145,105 workers. particulars are not available as to the number of working days lost. there were no features of particular interest in connection with the disputes; 1920 was the year most affected (517 disputes directly affecting 296,192 workers). france.—the latest figures available for france are for 1922. for the four post-war years the figures are as follows:— number of | aggregate wink number of | workpcople | duration in ° disputes directly working affected days i9i9 2.653 1,206,175 (6,128,638 1920! 1,924 1,487,996 | 24,563,527 ig2! 576 453,504 8,092,388 1922 711 307,056 3,335,902 1 figures for 1920 and subsequent years include alsace-lorraine. a noticeable feature in france has been the tendency to strike among employees of public bodies. germany.— during the post-war years (1919-23) the average annual number of disputes in germany was 3,762, which directly affected 1,657,469 workers and involved a loss of 23,158,100 working days on the average. the years 1919, 1921 and 1922 were the most serious. it should be noted that political motives were the cause of many german strikes in those years, e.g., the kapp putsch and the occupation of the ruhr. strikes and lockouts the netherlands —the average annual number of strikes in the post-war years (1919-24) in the netherlands was 380, which directly affected 50,567 workpeople and involved a loss of 1,687,983 working days on the average. in the year 1923 a dispute occurred in the textile industry, which affected 22,200 workpeople and caused the loss of 3,119,100 working days. the last figure is greater than the total loss in any other of the six years in all industries. scandinavian countries —widespread disputes in the spring of the year, when most collective agreements terminate, are a marked feature in the scandinavian countries: in denmark, for example, in the spring of 1925 an almost general dispute (strikes and lockouts) directly affected 93,000 workpeople and involved a loss of 4,021,900 working days. the average annual number of strikes, workers affected and days lost in these countrics in the post-war years was as fol- lows:— | number of | aggregate country number of | workpeople | duration in and years disputes directly working affected days denmark, 1919-24 . 164 27,748 892,609 norway, i921-4_. 58 61,168 2,405,946 sweden, i9qi9-24 78,724 4,114,706 a great lockout (feb. 14 to may 27 1924) in norway affected 39,476 workpcople and involved a loss of 2,962,263 working days. compulsory arbitration was in force in norway from 1916-21, when the act was allowed to lapse. it was renewed in 1922 for a year, but an attempt to renew it in 1923 failed. in sweden the peak year of the period was 1920, when 486 dis- putes occurred directly affecting 139,039 workpeople and causing a loss of 8,942,543 working days. spaint.—the average annual number of disputes in the post- war years (1919-23) in spain was 380, which directly affected 149,371 workers and involved the loss of 3,952,986 working days on an average. ill. british dominions canada.—the average annual number of disputes in the post-war years (1919-24) was 163, which directly or indirectly affected 52,580 workpeople and involved a loss of 1,716,577 working days on an average. the year 1919 alone accounted for more than one-third of the total number of working days lost. australta.—the average annual number of disputes in the post-war years (1919-24) in australia was 477, which directly and indirectly affected 137,226 workpeople, and caused a loss of 2,010,036 working days on an average. the year rotg alone accounted for rather more than half the total number of working days lost (6,308,226 out of 12,060,216). south africa.—the average annual number of disputes in the post-war years (1919-23) was 30, which covered 33,680' workers and involved a loss of 565,832 working days on an average. the year 1923 was distinguished by having only two strikes affecting 50 workers and involving the loss of 740 work- ing days. bintiocraphy.—great britain: the seventeenth abstract of labour statistics of the united kingdom, cd. 7733 (1915);

the workers were granted the basic eight-hour day and a check-weighman, but the union was not recognized. in 1915 there were 102 strikes and six lockouts of machinists between july and october. in nearly every case the basic eight- hour day was gained. the coal strike in that year involved 350,000 men. when the united states entered the world war in 1917 the american federation of labour discouraged strikes in the essen- tial industries. a number did occur, however, and these were mediated by government committees. on the whole the war period was one of industrial truce. during the war the greatest number of disputes occurred in the metal trades, building, cloth- ing, textile, transportation and mining industries. in 1917 a very violent disturbance occurred in the mines at jerome and bisbee, arizona. in july of that year 1,200 bisbee strikers were loaded on cattle cars by armed citizens and transported across the desert to columbus, new mexico. here they were taken over by sol- diers and fed on army rations for three months, after which they scattered. when the war was over the war labour adjustment boards were dissolved and workers, who had been prevented from strik- ing by the promise of peaceful sctilement, felt that the govern- ment and employers had broken faith. some 176,000 employees struck in the clothing trades, 150,000 in the textile industry, 100,000 marine workers anid 100,000 shipyard workers. the employers launched the “f american plan” of open shop and industrial unrest grew apace. in sept. 1919 the steel strike began as a result of the united action of 24 international unions. some 365,000 men left their jobs but gradually they went back to work. by jan. 1920 the remaining 100,000 men still out were sent back to work and the strike ended. in seattle a general sympathetic strike with the shipyard workers, involving 60,000 people, was called and lasted from feb. 6 torr. thestrike failed. in aug. 1910, although for- bidden by their national officers, 250,000 railway shopmen went on strike because of the delay of the wage adjustment board to reach a decision on the demands of the men for increased pay. after six days the strike was called off and the men returned! to work. at the request of president wilson the demand for a wage increase was postponed to give the government an opportunity to reduce the cost of living. in nov. 1919, 435,000 bituminous coal-miners struck for wage increases of 60%, the six-hour day and the five-day week in order to distribute work throughout the year. aninjunction was issucd to prevent the use of union funds for; strike benefits. in march 1920 an agreement was reached providing for a 27° increase in wages. in sept. rorg, 93° of the boston policemen struck for the right to organise and afhhate with the american federation of labour. their places were filled with other men. the coal strike of 1922 began on april 1, involving 600,000 men and effecting a complete tie-up of the central competitive (bitu- minous) field and of the anthracite industry. the operators strindberg—stsherbatsky wanted the creation of a permanent arbitration board, and the union wanted the creation of a government fact-finding com- mission and the continuation of collective bargaining. this, rather than wages, came to be the real issue in the anthracite strike. an agreement was reached on sept. 2, providing for the continuation of existing wages and ‘recommendation to congress that a coal commission be appointed. the bituminous operators wanted district agreements, the union wanted a national agree- ment. the union demands included also continuation of existing wages, the six-hour day and five-day week. an agreement was reached aug. 15, providing for cessation of the strike, and appoint- ment of a joint committee to negotiate a wage scale to go into effect april 1 1923. the strike of the railway shopmen began july 1, involving 500,- coo men and constituted the most complete tie-up of that branch of the railway industry that the united states has ever seen. the shopmen struck primarily against the road’s practice of con- tracting out work to non-railway shops and against the basic wage of $800 a year established by the railroad labour board. on sept. 13 the unions and 50 railways signed an agreement which 126 roads signed by oct. 27. the most important strike in 1923 was that of 155,000 an- thracite coal-miners in september for the check-off of union ducs and a 20% increase in wages. the strike was settled after three weeks on a compromise basis, the miners securing a 10% wage increase. in may, 50,000 new york city clothing workers struck for a 10% wage increase. the strike lasted two weeks, embraced 2,000 shops and was won by the workers. the most important strike of 1924 was in the ladies’ garment industry. on july 8, 50,000 workers led by the international ladies’ garment workers union struck for an increase in wages, a 40-hour weck and unem- ployment insurance. the strike lasted 13 days and was a success. industrial disputes were in general less numerous and less severe in 1925 than in any preceding year except the very quiet year of 1922. during the first half of 1925 some 720 strikes and lockouts involving 199,500 people took place. during the third quarter of the year 363 disputes occurred. the principal cis- putes were in the clothing, textile, building and coal-mining in- dustries. ‘the most important strike was that of 148,000 an- thracite coal-miners which began sept. 1, in a demand fora 10% wage increase, the check-off of union dues, two-year contract and complete union recognition. the strike lasted 170 days and covered the entire commercial anthracite area. an agreement ratified feb. 17 1926 continued the terms of the previous con- tract, and sect up a board of conciliation and other arbitration machines. the agreement is to be in force until aug. 31 1930. new york dressmakers, numbering 30,000, struck on march ro in 2,000 shops to enforce a provision in the joint agreement. the strike was novel in that the strikers reported at their places of work each morning and sat at their machines for six days with- out working. the strike was asuccess.

(j... rco.) strindberg, august (18409-1912), swedish author (see 25.1038), died at stockholm may 14 1912. his plays have been translated into english by e. and w. oland (1912-3) and h. b. samuel (1914). see a. henderson, european dramatists: august strindberg (1914); c. d. marcus, strindbergs dramatik (1918); c. l. schleich, drinie- rungen an strindberg (1917). strzygowski, josef (1862- —+),:- austrian scholar, was born at bial, near bielitz, march 7 1862. in 1892 he became a pro- fessor at graz, and in 1909 was appointed professor of art at the university of vienna. he wrote numerous works on art, dealing especially with oriental influences on western art (see byzantine art, 4.907; roman art, 23.475). his works include: byzantische denkmdler, 1-3 (1891-3): hellen- astische und koptische kunst in alexandria (1902); koptische kunst (1903); die bildende kunst der gegenwart (1907); orsprung der christlichen kirchenkunst (1920, swedish and english trans.); ed. early north european church art and wood architecture (1925). stsherbatsky, fedor ippolitovich (1867- _—+), -rus- sian orientalist, was born at st. petersburg (leningrad) sept. sturdee—submarine 19 (old style) 1867 of a family of old nobility. ife was educated at tsarskoye selo, and studied philology at the st. petersburg university, specialising in sanscrit under prof. i. p. minajev. he graduated in 1889 and studied three years abroad, first at vienna under prof. g. biihler, then in bonn, under prof. h. jacobi. in roo4 he became professor of indian literature at the st. petersburg university, and in 1916 was elected member of the prussian academy of sciences. the years roro-1 were spent in british india for scientific research. his knowledge of tibetan languages and of buddhism enabled him to enter into friendly relations with the leacling buddhist priests. he was invited to meet the dalai-lhama, with whom he had several interviews without any interpreter. his thorough understand- ing of buddhism makes his work, the theory of knowledge and logic according to the later buddhists (1899), a most valuable book (german translation, 1924). he has published many sanscrit mss. in the bibliotheca buddica of the academy of sciences. in 1923 the royal asiatic society published his work, the central conception of buddhism, and in 1926 was published the conception of nirvana. sturdee, sir frederick charles doveton (18s50- 1925), british sailor, was born at charlton, kent, june 9 1850, and entered the navy in 1871. he was promoted licutenant (1880), commander (1893), captain (1899), rear-admiral (1908), vice-admiral (1913), admiral (1917) and admiral of the fleet (1921). he saw service in egypt (1882) and in samoa (1899), when he was in command of the anglo-american force. he was assistant director of naval intelligence to the admiralty (t900-2) and chief of staff, mediterranean fieet (1905-7) and channel fleet (1907). in 1g10 he became rear-admiral of the first battle squadron, and commanded the 2nd cruiser squadron (1912-3). during the world war sturdee was made chief of the war staff in nov. 1914. as commander-in-chief in the south atlantic and pacific, he led the squadron which won the battle of the falkland is. dec. 8 1914, and he was in command of the 4th battle squadron when it took part in the battle of jutland. he was created k.c.b. in 1913, k.c.m.g. in 1916, and a baronetcy was conferred on him in 1916, with the title “of the falkland is.” from to1r8-21 he was commander-in- chief at the nore. he died may 7 ro25. sturdza, demetrius (1833-1914), rumanian statesman (see 25.1051), died at bucharest oct. 21 1914. sturgkh, carl, count (1859-1916), austrian politician, was born at graz oct. 30 1859, of an ancient noble styrian family, and in 1881 he became an official of the statthalterei at graz, and later of the ministry of education. he left the state service in 1891, when he was elected as a representative of the loyal land- holding interest to the reichsrat. he attached himself to the left of the german party, and came forward as a keen opponent of universal suffrage. he was from feb. 10 1909 to nov. 3 1911 minister of education, and a zealous advocate of the humanistic education traditional in the gymnasia. on nov. 3 he became prime minister. stiirgkh was one of the committee of five min- isters who decided on the dispatch of the ultimatum to serbia and the declaration of war, which brought on the world war. he was killed on oct. 21 1916 by a shot fired by the social democrat freidrich adler, a son of the social democrat leader, viktor adler, as a protest against stiirgkh’s government without parlia- ment (see austrian empire). stursa, jan (1880-1923), czech sculptor, was born at nove mesto in moravia. in 1899 he entered the academy of fine arts at prague as a pupil of myslbek. his early works manifest the influence of the symbolic literature of that period, but by 3905-7 he had already attained an individual expression in such works as “ puberty ” (1905), ‘‘ the melancholy girl ” (1906) and “ primavera” (1907). a journey to italy in 1907 was the opening of a new epoch in his creative work. he was captivated first and foremost by the warm magic of femininity which is manifested in “ eve” (1908, state gallery, munich), “* hetaira ” (1909), “‘ messalina ” and the monumental represen- tation of the dancer “ sulamith rahu” (1911), now in the gallery at venice. at the same time he interpreted the oppo- 663 site feminine type, the intellectuality of which is incorporated in the monument to hana kvapilova (1912), the famous czech actress. during the same period stursa produced the group of statuary for the pylons of the hlavka bridge at prague. in 1916 he was appointed professor at the academy of fine arts in prague, and it was in this period of his artistic maturity that he created the “‘ wounded man.” he also produced a number of portrait busts, the most noteworthy of which is that of president masaryk. the leader of the modern school of czech sculpture, he died in 1923. sturzo, luigi (1870— ), italian priest and_ political organiser. born at caltagirone, sicily, on nov. 26 1870, he entered the priesthood at an early age, but soon took to politics and showed from the first a marked ability in creating diocesan committees, co-operation unions, etc., and guiding the masses in the direction of christian democracy. ie was practically unknowh outside his native province, until on the outbreak of the war, he came to rome as secretary of the azione cattolica. after the armistice he was chosen political secretary of the partito popolare italiano, founded early in rgtg. there had been a political catholic movement in italy even before the war, but it was due to the organising genius of don sturzo that the partito popotare made such rapid progress in so short a time. the general tendency of the party was christian socialist, and don sturzo advocated social reforms of a radical nature, espectal- ly in agriculture, as the majority of the party’s adherents were peasants; unlike the socialists, he demanded the expropriation of the land with compensation for the landlords, collaboration of capital and labour in industry and a patriotic foreign policy. but an extremist wing, led by sig. miglioli, soon arose, and don sturzo, although mildly critical of its bolshevik methods, never definitely disowned it. at the elections of nov. t9109, thanks to the proportional system introduced by nitti, the partito popolare secured 101 seats, and subsequently, by holding the balance between the various parties, became a dominant force in italian politics. when sig. bonomi was trying to form a cabinet after the fall of giolitti in feb. 1922, it was don sturzo who dictated its composition to him and became his eminence grise after it was constituted. in the early days of fascism don sturzo did not oppose it, although there were frequent affrays between the black-shirted squadre and the migliolini. after the march on rome he allowed several popolari to enter the cabinet, but his half-hearted support of the mussolini govt. resulted in their withdrawal, and don sturzo and his party definitely joined the opposition. <a section of the party, having remained faithful to sig. mussolini, broke away from the partito popolare and constituted the centro nazionale cattolico. don sturzo’s activities had, however, brought him into dis- favour with the vatican, which, after issuing a general ad- monition to priests not to mix themselves up with party politics, hinted that he would be well advised to leave italy. he con- sequently went to england and france. in 1925 he published pensiero antifascista. (ls v.*) submarine.—the first practical submarine was constructed by david bushnell in 1775, and his ideas were revived some 25 years later by r. fulton, who constructed a boat called the ‘““ nautilus,” driven by means of a hand-worked screw and fitted with a copper vessel containing compressed air to give a reserve supply for breathing. this air enabled the boat to remain under the water for about four hours. the vessel actually descended on trial to a depth of 25 ft. and placed a torpedo underneath a ship. the submarine before the world war american civil war.—the first vessels to take part in actual warfare were of a type known as the davids, built by the con- federates during the american civil war. these were small iron boats propelled by hand from four to seven knots and armed with a spar torpedo bearing about 50 to 70 lb. of powder. one of these, manned by nine men, attacked the federal warship ‘‘ housatonic ” and sank her, but was herself sunk by the wave thrown up by the explosion. about 1860, the submarine boat 664 began to slowly develop from the crude form propelled by man- ual labour to a power-propelled vessel, which could be con- sidered a factor in naval warfare. in 1863 the ‘ plongeur,”’ 146 ft. long, 12 ft. in diameter, and propelled by an 18-h.p. compressed air engine, was built in france. the “ holland” type.—a very important type was con- structed in 1877 by mr. holland, which was propelled by a petrol engine. for the purpose of diving, water was admitted into internal ballast tanks until the boat had a small positive buoy- ancy, immersion being maintained by the use of horizontal rudders. the importance of this type is due to the fact that the first submarines for the british navy were based on mr. hol- land’s ideas. the following are a few of some of the other types of submarines built by the various naval powers round about this period. russtaz bouts in 1881, m. goubet constructed several submarines for the russian govt., 163 ft. long, of oval sec- tion, 57 ft. by 3] ft. amidships, tapering ito a point at each end. the boat was manned by two persons only, and all valves and other mechanism were brought within reach of the two oper- ators in order that no movement which might upset the trim of the boat was necessary. the power for driving the screw pro- peller was obtained from an electric motor driven by accumu- lators, and submersion was effected by admitting water into ballast tanks, this water being expelled by a pump when the boat was required to be brought to the surface again. construction in u.s,a.—in 1887 the united states of amer- ica invited designs for submarines, and after careful considera- tion of all those submitted the holland design was accepted and formed the basis of the designs for the “ plunger,” the ‘ hol- land ” and the six vessels of the “‘ adder” class. he latter were single screw boats, 63 ft. long, 104 tons surface displacement and were driven on the surface by petrol engines, giving a speed of about 83 knots. when submerged, an electric motor supplied from accumulators was used, giving a speed of seven knots. they were armed with one bow torpedo tube and carried five torpedoes, and, as in the original holland design, they were submerged by admitting water into internal ballast tanks and then dived by the aid of horizontal rudders. another interesting type was the ‘‘ narval”’ design by m. laubeuf and constructed in 1899. she was 112 ft. jong, 12 ft. 4 in. beam, displaced 104 tons, and had a surface speed of 11 knots and eight knots submerged. ‘the machinery was a triple expansion steam engirie, obtaining steam from a water tube boiler burning petroleum. this formed the motive power for - surface propulsion and also the power for driving the dynamo for recharging the accumulators, which furnished the power in the submerged condition. the vessel had a double hull and was submerged by admitting water into the space between the inner and outer hulls, control in the horizontal and vertical direc- tions being effected by rudders fitted forward and aft. great britauin—in 1g00 five “ holland” type boats were ordered for the british navy, which were practically identical with the boats of the american “‘ adder ” class previously men-~ tioned, after experience with these, 13 boats of an improved design were laid down in 1902 and known as the “a”? class, followed by 11 boats of the “ b ” class, completed between 1905 and 1906, and then 38 of the “ c” class, completed between 1g06-to. all these boats were armed with two torpedo tubes, and all except the a.13 were driven by petrol engines on the surface and electric motors when submerged. the a.13 was fitted with heavy oil engines for surface propulsion. in 1907, the first of a larger and improved type, known as the “d ” class, was laid down, particulars of which were as follows: length 162 ft., breadth 20 ft. 6 in., draft 11 st., surface displace- ment 500 tons, submerged displacement 620 tons; horsepower on the surface 1,200 h.p., submerged soo; speeds 145 to 15 knots on the surface and nine to 10 knots when submerged. this “ d ” class immediately preceded a somewhat similar type of vessel, which formed a very large proportion of the number of subma- rines in the british war flotilas. in these vessels a more radical departure from the parent submarine holland type was made than in the “ a,” “ b \"and “c ” classes, main ballast tanks being introduced on the outside of the main circular pressure hull. the hull shape was modified by the adoption of twin screws driven by vertical four-cycle diesel engines instead of the single screw driven by horizontal petrol engines in the previous boats, the disposition of the twin bow torpedo tubes vertically instead of horizontally, and the provi- sion of a stern torpedo tube. these departures from the previous type were made with the objects of increasing the endurance of the boats at sea and of eliminating the risks attending the use of petrol. the external tanks enabled the reserve of buoyancy to be increased, thus rendering the boats less liable to founder sud- denly in case of collision or similar accident, and making them more habitable at sea. a r2-pdr., on a mounting which was housed inside the super- structure and operated by compressed air so as to pass rapidly from the firing to the housing position, was installed in ‘ d4” and was the first instance of the mounting of artillery on a sub- marine. up to this time the british submarines only had tor- pedo tubes forward and aft, but a demand arose in the fleet for broadside tubes, and to mect this demand the “ fe” class was designed for the t910-1 programme. the provision of the two broadside tubes in the “ e” class was the chief cause of the difference in dimensions between this class and the “ d's,” but of course this increased size had its natural concomitant in increased power, speed, habitability and endurance. in the first ‘ e’s,”’ one bow tube only was fitted, owing to reports against these tubes having been received, but in the later “ e’s ” of the 1911-2 programme the two bow tubes were again fitted. this class also was the first to have the main hull sub-divided by transverse bulkheads, thus increasing the safety of the boats in case of ac- cident, and also increasing the strength of the hull against exter- nal pressure. these vessels proved themselves a very suitable and reliable type in many ways. two of them, a.f.1 and a.i..2, proceeded under their own power to australia and took up duties with the australian navy. one of them had over 30,000 m. to her credit before it was necessary to ret the propelling machinery. as seagoing boats they were a distinct step in advance of previous classes. the extensive superstructure, combined with the nav- igating bridge built over the conning tower, made them easy: to navigate in even the roughest weather. this advantage is the more appreciated when it is understood that only in the finest weather could a “b” or “c” class boat cruise on the surface with open hatches. the overall length of the “ e’s ” was 181 ft., beam 22 [t. 7 in. over the side tanks, and the displacement when submerged was 780 tons. the torpedoes carried were 18 in. in diameter, and a spare torpedo was carried for each tube, making eight torpedoes in all for the original “ e’s”’ and 10 for the later boats. a 12-pdr. gun was also carried. the endurance at a cruising speed of to knots was 2,650 naut. m.on4s tons of oil. a surface speed of 15 knots was obtained, the power being provided by two vickers heavy oil engines, each of soo brake horsepower. the motors for use when submerged each developed 420 b.h.p., giving a speed of 1o knots. the power for the motors was provided by two separate batteries, each of 112 cells. air storage was provided by 57 bottles stowed about the ship, the bottles being charged by high pressure air com- ptessors. to equip these boats for more effective scouting and patrol work a wireless installation was filted, the aerial being carried on folding masts. in addition, a set of under-water signalling gear was fitted. two periscopes were carried, one being a simple single power instrument, the other being arranged for use with varying powers and also for use as a ‘‘ sky searcher ” for detecting aircraft. another type of submarine with a complete double hull was developed by messrs. vickers, and four of these boats were ordered and called the “ v ’’? class. these were 147 ft. 6 in. over all, beam of outer hull 16 ft. 3 in., and submerged displacement 460 tons. the speeds were 13 knots on the surface and 83 knots when submerged, the armament consisting of two 18-in. bow tubes. the “ g ” class followed upon the vickers design and was submarines plate types of modern submarines fic. 1. h.m. submarine l. 16.

submerged displacement of 970 tons. the “ g’s ” dimensions followed the single hull “ e ” class very closely but with increased displacement, consequent on the pro- vision of the double hull. their full surface speed was 14-15 knots, obtained by twin heavy oil engines, each of 800 brake horsepower. submerged, the speed was 10 knots with 2 motors each of 420 brake horsepower. the armament was two bow and two broadside 18-in. torpedo tubes and one stern 21-1n. tube, with, in addition, two guns mounted on the superstructure, one being a disappearing 3-in. ‘‘ q.f.” type and the other a 2-pdr. “ h.a.” the submarine during the war world war construction and types.—in the early months of the world war a large number of “ e” boats were ordered, in addition to some to the design of the electric boat co. of amer- ica. the first batch of these latter, known as the “ h”’ class, were built at messrs. vickers’ canadian establishment at montreal, and later, more were built by messrs. vickers at their home works to a slightly modified design to enable them to carry a heavier armament. these were 171 ft. 9 in. long, 15 ft. 9 in. beam, and of 510 tons submerged displacement. the speeds were 13 knots on the surface and 10 submerged. the chief feature in this class was the very powerful torpedo armament carried in relation to their size, four 21-in. torpedo tubes being arranged in the bows and six torpedoes carried. another interesting type of submarine was the “ j ” class, the first of which were ordered at the beginning of 1915. these were the fastest internal combustion engined boats in the world, since they obtained a speed on the surface of over 19 knots. they were of the double hull type, 275 ft. long, 23 ft. beam and 14 ft. draught, displacing on the surface 1,210 tons, and when submerged 1,820 tons. tor surface propulsion three sets of oil engines were fitted, giving 3,600 s.h.p. the horsepower for sub- merged propulsion was 1,350. four bow and two broadside tubes were fitted for firing 18-in. torpedoes, and in addition one 3-in. or 4-in. h.a. gun was mounted. as the submarine requirements during the world war of the main fleet increased, it became necessary to have a type which, whilst still retaining the ordinary functions of the submarine, could yet maintain station with the fleet when cruising. this involved a higher speed on the surface than the “ j ” class, and the necessary requirements were embodied in the design of the ““k ” class. these vessels had a submerged displacement of 2,560 tons and a surface displacement of 1,880 tons. they are 338 ft. long overall with a beam of 26 ft. 6 inches. the double hull principle is embodied in a modified form, the ends of the boat, which might be damaged without endangering its immediate safety, having only a single hull at the sides. the speed was 24 knots, the power being obtained from twin sets of geared steam turbines developing a s.h.p. of 10,500, the steam _ being obtained from two yarrow boilers. the funnels were ar- ranged to hinge down when preparing to dive, and water-tight hatches covered the funnel openings as the latter hinged back. the turbine machinery was supplemented by an 800 b.h.p. heavy oil engine, coupled up to a dynamo. this arrangement enabled the turbines to be reserved for higher speeds only, whilst the dynamo, in addition to charging the batteries, supplied the main motors with power for cruising at economical speeds. sub- merged, the speed of these vessels was nine knots. the turbines are installed in a separate compartment, water- tight bulkheads being provided at the forward and aft ends of the compartment, with two doors in the former, one for access to the boiler room and one to the main passageway to the fore part of the vessel, and one in the latter for access to the motor room. the boiler room contained, in addition to the boilers, feed and oil pumps, heaters and filters, and forced draft fans, the latter driven by impulse steam turbines. the hinged funnels are lowered and the opening closed simultaneously by means of an electric or hydraulic motor and similar covers for the boiler room air vents are also hydraulically operated. 665 additional protection for the navigating officer and quarter- master was provided in the form of a deck house built over and around the ordinary conning tower. the periscope fittings were the longest fitted up to that time, being 30 ft. from eve-piece to head-piece. another important accessory was the long-distance wireless installation, the aerials being carried on telescopic masts, enabling the commanding ofhicer to keep in touch with his base when operating a very great distance from it. a telemotor system was installed for raising the periscopes and tclescopic masis, and also for working the ballast tank vent valves, and the introduc- tion of this hydraulic power for such operations made such large submarines a practical proposition. the armament of this class was four bow and four broadside 18-in. tubes, with a spare torpedo for each tube, and in addition three guns, two 4-in. and one 3-in., for high angle work. ‘these vessels were self-con- tained units of the fleet and did not rely on a parent ship as in the case of the “‘ e ” and other classes. further developments.—as the war progressed it became necessary to add more submarines to the fleet, and the first of the ‘‘l” class, the design of which was based on the very successful “‘ e’s,” was ordered towards the end of 1917. these combined the best qualities of the previous boats with an in- creased speed over that of the “ e” class. (see viate, fig. 1.) the circular single hull was used with the side ballast tanks as in the ‘‘ e ” class, and in the first design for these boats the stern was wedge shaped, as in the ‘‘ e”’ and “‘ h_”’ boats, but a second design had an improved duck stern, like the j” and “k” classes. the length extreme is 231 ft., the beam near the side tanks 23 ft. 6 in., and the total submerged displacement 1,070 tons, with a surface displacement of 890 tons; 12-cylinder oil engines, developing a total b.h.p. of 2,400, gave, with twin- screws, a speed of 173 knots on the surface, and the submerged speed, with a total b.ii.p. of 1,600, was 103 knots. the torpedo equipment in this class consisted of four 18-in. or 21-in. tubes in the bow and two 18-in. in the broadside room, with a spare torpedo for each tube. a 4-in. gun was mounted on the super- structure just forward of the bridge and conning tower. a novel feature was the night periscope fitted, which enabled the crew to keep a more effective watch at night. the “ mf” type.—another outstanding type of boat was the ““m ” class, which were really submarine monitors built to carry a r2-in. gun. they were of the double hulled type, 296 ft. long, 24 ft. 6 in. beam, and with a draught of 15 ft. 9 in. had a dis- placement on the surface of 1,600 tons, becoming 1,950 tons when submerged. the speeds were 16 knots and 93 knots on the sur- face and submerged respectively, the horsepower of the machin- ery being as in the “ l”’ class boats. in addition to the 12-in. gun a 3-in. hf. a. gun was carried, and the torpedo armament consisted of four 18-in. bow tubes. only three of these boats were completed, the last being delivered from messrs. arm- strong’s, the builders, in oct. 1920. (sce plate, fig. 2.) the “ r” class.—the “ r”’ class, ordered late in 1917, were small vessels of single hull type, as the original holland boats, built as a “submarine destroyer of submarines ”’ or “ contre- submarine type.” ‘their outstanding feature was that, unlike all other submarines in the world, they were faster below the water than on the surface. the speed submerged was 15 knots with 1,200 h.p., and that on the surface was 9$ knots with 240 h.p., the armament consisting of six 18-in. bow tubes. these boats were intended to submerge and chase the german u boats and use their six bow tubes by salvo in order to destroy them. only two of these vessels were in the service in 1926. aminclayers—another type developed under the stress of world war requirements was the minclaying submarine, and several of the “le.” and “\\l” classes were equipped for this service. the mines were loaded into vertical tubes, which passed through the external tanks, and mechanical gear was fitted for locking the mines in position and releasing them when required. performances.—the k26, a boat built to an improved “ k ” design, completed in 1923, undertook a world voyage in 1924. she left portsmouth on jan. 2 1924 for gibraltar and malta, arriving on jan. 14. after the fitting of special ventilating 666 submarine table“: c displace- spced horsepower ee launched} length breadth draught ment armament surf. | sub. | surf.| sub. |} surf. | sub. ft in {t in {t in tons | tons] kts. | kts british ee i91o iq9ii 162 o 20 6 il o 500 | 620 | 143 | lo |1,200 | 550 | 3 18-in. t.t. france. 1910 iqii 166 6 16 4 10 5 4o2 | 496 | 12 8 700\"! 440. |e t6-in,, tals 18-in. in exter- nal frames. 1909 1909 i99 «10 18 6 13 7 570 | 797 | 15 10 | 1,700 1 18-10; (v1, 18-in. in ee nal frames. germany : i91o i9io 180 re) 18 6 11 o goo | 550 | 13 9 1000 | 600 | 4.17-7-1n. t.t. italy : : i9ii iqii 148 o 13 9 9 9 | 249 | 295 | 13 85 | 600 | 4oo | 2 18-tn. t.t, japan. iqii iqii i34 10 13 8 280° 4°34) 13 8 600 | 400 | 2 18-in. t.t. united states” i91o 1910 140 o 14 oo 278 | 340 | 13 9 600 | 400 | 4 18-in. t. t. arrangements, she continued her passage through the red sea and length 350 ft., beam 29 ft., 10 in., draught 17 ft., surface displace- thence to colombo and singapore, at which places she arrived | ment 2,525 tons, ‘submerged displacement 3,600 tons. the cost of . ae j : this ve sscl, excluding the armament, is estimated at about £950,000. respectively on april 29 and may 14. leaving singapore on the original british holland boats particulars were as follows: june to, she arrived in england at portsmouth on aug. 26. | length 63 ft., beam 113 ft., surface displacement 104 tons, sub- at the time of this cruise the k26 was the largest and heaviest | merged displacement 120 tons. submarine in service in any navy. since then, however, further france.—in the early stages of the submarine, france dis- developments have been made in large submarine design, the | played greater originality, due to the fact that in that country x7 holding pride of place as the largest submarine in the | there was a strong school of thought which even then con- world in 1926, her dimensions being as follows:— sidered that the vessel would drive surface war vessels from the table: -11, displace- : apes speed horsepower type and class length | breadth | draught | armament crew » ) sark. | stib,. | surk,.) sub; surf. sub. ft ft ft tons | tons | kts kts ordinary u type class u86 . . 230 203 13% 800 | 940 | 163 8 2,400 1,180 | 2 bow t.t.'s, 2 stern t.t.’s, 1 4-1-in. gun, i 3:5-in. a class ui6r ‘ ; 235 2175 12} 828 | 1,018 | 153 8 2,400 1,160 | 4 bow t.t.’s, 2 stern t.t.’s, 2 ha guns, eee es ua cruiser or uk tye class u135 2753 25 144 i,1i90 | 1,560 | 16 7 main 3,500, | 1,940 | 4 bow t.t.’s, 2 stern| 46 aux. 900 t.t.’ s, i §-9-in. gun, | i 3°5-in. gun, class u139 - 3023 29} 154; | 1,950 | 2,500] 15-8] 7-4 | main 3,500, | 1,760 | 4 bow t.t.’s, 2 stern aux. 450 6 a bae ee 59° in. guns| .. class ur42 ; ; 320 215 17iz | 2,160 | 2,760 | 18 8 main 6,000, | 2,600 | 4 bow t. 7 s, 2 stern] 83 aux. 550 t.t.’s, 2 5-9-in, guns. ub or coastal type class ubi-17. .. q2 10} 10 128'| 143°] 63 5} 60 120 rat ge a a 6 gry a | incn). class ub18-47 ... 118} 14} 12} 275! 304] 9 5:8 282 280 | 2 bow t.t.’s (19-7-| 23 in,), i mach. gun, i 2-in. or 3°5-in. gun, see class ub48-136 181} 194 i2 521 657 | 133 7% 1,100 760 | 4 bow t.t.’s, 1 stern| 34 t.t.

(bt... bs submarine campaigns.—the submarine was a new weapon of as yet unknown capabilities in aug. 1914 when the world war broke out. the british had some 56 submarines of varying ages, the 18 newest boats of the d and e classes being grouped in the 7th flotilla and based on harwich. in charge of the whole submarine service was commodore roger keyes who also took an active part in their operations. the 7th i'lo- tilla was used throughout the war mainly in keeping a more or less continuous watch on the mouths of the german rivers and in other places where german warships might be expected. the a and b classes were fit only for coast defence. the c class which could keep the sea for a few days guarded the forth, the thames and the straits of dover. germany, in aug. 1914, had 28 submarines of which the first batch, ur to u18, had an unsatisfactory type of engine and could be relied on only for short voyages or for guard duties near home. urg to u28 were able to make longer journeys, but to what extent was as yet unknown elther to germany or to england. i. the opening phase both belligerents, at the outset, had the same ideas as to the method of employment of a submarine in war; it was to be used for attacking warships. it carried no guns since it could not use them without coming. to the surface to fire; and its only armament consisted of torpedoes to be discharged when the boat was submerged. campaign of torg.—it was expected by the german naval authorities that, on the declaration of war, the british navy would immediately appear in heligoland bight to make an attack in force; the submarines were therefore sent to defence stations to mect the impending attack. when, after two days, no british ships appeared, the german command determined to attempt to locate them and 10 u-boats proceeded to the north sea on aug. 6, sweeping in line abreast. this was the first time so many submarines had acted as a squadron, and much was hoped from the operation; but only 8 boats came back, and they had little to report. one boat, urs, had seen some of our cruisers, only to be cut in half by the “ birming- ham.” of the fate of the other lost boat, u13, nothing definite is known. the reconnaissance had proved too costly; a squad- ronal attack by submarines was not repeated, and thenceforth the u-boats operated singly. further attempts were made throughout aug. to find the british main flect; when these also failed, the german command definitely decided to abandon submarine operations against the grand fleet, and use the boats in attacking smaller men-of-war than capital ships. the first submarine success of the war was achieved by hersing, who in uar on sept. 5 sank the light cruiser “ pathfinder ” off st. abbs elead. a week later horton in eg sank the light cruiser “ hela” in heligoland bight, with the result that the high sea fleet abandoned the bight as an exercising ground. the most resounding event of the campaign of 1914 was the sinking of the “ aboukir,” ‘ hogue ” and ‘‘ cressy ” with over 1,200 men on sept. 22 by weddigen in ug. though the feat was an easy one, for the ships conveniently stopped to lower boats and waited to be torpedoed, its effect was to raise the submarine in the esti- mation of both belligerents from a difficult and dangerous toy to a formidable weapon. imaginative lookouts saw submarines everywhere and after a credible report that periscopes had been submarine campaigns seen in scapa flow, the grand fleet withdrew from there on oct. 16 till the flow could be made secure by submarine-proof net-booms. in actual fact, no u-boat had yet been near scapa. it was in southern waters, in an attempt to hamper the transport of our troops to france, that the german effort had been directed. an attack on the dover patrol on sept. 27 decided the admiralty to prevent entrance into the straits of dover by a minefield. this was laid early on oct. 3, the public announcement of its limits being made to the press the evening before. possibly the ger- mans regarded the minefield as existing only on paper; their submarines continued to enter the channel by the straits. u2o left on oct. ro to attack the large convoy of canadian troops expected at southampton. she was sighted and hunted by the dover patrol, and returned to germany by the northabout route, being thus the first submarine to circumnavigate the british isles. ury, returning from a cruise, stopped the british merchant ship ‘ glitra ” off stavanger and sank her. this was the first merchant ship to be sunk by a submarine. before the year ended wegener in u27 sank a scaplane carrier off the belgian coast and forstmann in ux2 penetrated into the downs and torpedoed the guardship “ niger ” in the middle of all the shipping congregated there. of our own submarines e3 was torpedoed by wegener off the ems; the other e-boats had had little success though horton succeeded in sinking a german destroyer on oct. 6. a bold attempt was made by 5 u-boats to locate the grand fleet; one of them on oct. 24 entered scapa flow, once more the grand fleet base, but at the time the battle fleet happened to be out exercising. one of these 5 u-boats, u18, was hunted by small craft till she crashed on to the orkney rocks and sank. once more the submarines returned without precise information of our capital ships, and the stream of trans- ports passing to france became as before the chief objective. schneider in u24 torpedoed a crowded steamer off cape gris nez, assuming that the passengers were soldiers, but they were belgian refugees, women and children, and the crime gave a shock to the civilised world. hersing in u21 destroyed two ves- sels bound for havre, though neither was carrying any goods consigned to military authorities. the leisurely nature of his proceedings in stopping the vessels gave plausibility to the cur- rent idea that a merchant ship with hidden guns would have a good chance of destroying a submarine; and on nov. 26 the admiralty gave orders for one to be so fitted, the railway steamer “ victoria,” which left for her first trip three days later. she was the first of the long and honourable line of the so-called “ q” ships. hersing’s operations off havre led to the institution of two measures which rendered the troops for france more safe; from that time on they were allowed to cross only at night in fast ships and these were always escorted by destroyers. on new year’s day the old battleship “ formidable’ was sunk by schneider. this first campaign extended to the end of jan. ig1s. at the end of that month hersing appeared off barrow- in-furness, fired a few shots at an airship shed after having been watched for half an hour by the battery commander, and then proceeded to liverpool bar where he sank by bombs three small steamers. schwieger in u2o proceeded to the channel with orders to sink without warning large vessels steering for french ports; he carried out these instructions so thoroughly that three ships approaching havre diswppeared, one, the “ onole,” with no survivor. schwieger became later one of the most notorious exponents of ruthlcss submarining. so far the campaign had been against normal objects of war- fare—warships, transports, military works. but its results were insufficient to warrant the supposition that by submarines and minor weapons could germany ever succeed in reducing the british navy to an equality with her own. after considerable debate and hesitation she decided to use her submarines against a new objective. u. the attack on commerce submarine blockade declared.—early in jan. admiral von pohl, chief of the german naval staff, proposed that submarines submarine campaigns should be used as the agents in a commerce blockade of the british isles. at first the kaiser refused to sanction the measure, but he consented after the fight on the dogger bank on jan. 24 had demonstrated the danger of operations by large ships. on feb. 2 appeared a note warning neutral shipping to avoid the channel, where german submarines would attack vessels bound for france, regardless of the flag carned. this was followed on feb. 4 by a wider statement that after feb. 18 enemy vessels near the british isles or in the english channel would be de- stroyed, and that neutral ships ran grave risks of being treated in the same way, since british ships frequently wore neutral ensigns asa ruse. scandinavian vessels were advised to go round the shetlands. anti-submarine measures, feb. 1915.—great britain used the - fortnight’s respite in preparations to mect the attack. to de- stroy the german submarines in their own bases was realised as impossible without large armies, and these the military authori- ties preferred to use on other fields. beyond the laying of mines in german waters, anti-submarine war was therefore limited to defensive measures. fifty coasting vessels were provided each with a gun aft. there were already a number of trawlers armed and working as auxiliaries to the east coast destroyer patrol; this “‘ auxiliary patrol’ was now increased to over 500 vessels and distributed round the coast to operate from various bases. trawlers and destroyers in many cases were already fitted to tow an explosive charge with which to attack a submerged sub- marine; but what was felt to be the most hopeful weapon was the “indicator ” net, of 6-ft. mesh in large detachable sections each trailing a buoy which should flame at night. these nets were shot from drifters, each of which could manage a mile of them. arrangements were made for indicator net lines to be maintained in various places, particularly in the north channel between ireland and scotland, across the southern exit of the irish sea, and, most urgent of all, across the straits of dover. so important was this last that rear-admiral hood, command- ing at dover, was instructed that the barring of the straits was his principal duty. | campaign in home waters, 1915.—-tyo carry out the ambitious project of stopping the imports of great britain, germany had only 18 submarines capable of long voyages, the highest num- bered boat being u35. but over 160 of various types were build- ing or on order. the first boat to proceed for the new campaign was u16 (hansen), which left germany on feb. 9 for the chan- nel with orders that up to feb. 15 only ships about to enter french ports were to be destroyed without warning; after that he should sink any vessel which might seem to be bnitish, re- gardless of the ensign she wore. on the way to dover strait, hansen gave chase to the steamer “ laertes” (capt. w. h. propert), who, though his vessel was unarmed, refused to sur- render in spite of machine-gun fire, and eventually tired out his pursuer. in the channel, hansen torpedoed a british collier without warning, sank a french collier by bombs after surrender, and returning on the 19th torpedoed without showing himself the norwegian tanker “ belridge,”’ the first neutral to feel the sting of germany’s new campaign. his place on the transport route to france was to be taken by u6, but that boat was rammed off beachy head by the steamer “‘ thordis ” (capt. j. w. bell), and had to return for repairs. during the first week of the campaign, feb. 18 to 25, u30 sank two vessels off liverpool and u8 torpedoed without warn- ing 5 off beachy head. observing that such landmarks as this were places where shipping naturally converged the admiralty now insisted that ships should avoid all prominent headlands and keep in mid-channel; and in the hope of rendering dover impassable obtained on march 1 treasury sanction for the building of a fixed boom of nets from folkestone to gris nez. this proved a formidable and indeed hopeless undertaking; and throughout this campaign the destroyer patrols and the drifting nets were the only obstacles to the passage of submarines. the base at zeebrugge—u8 had come from zeebrugge. as soon as the germans captured the belgian coast they estab- lished a naval corps there under an admiral. he repeatedly 669 urged the favourable situation of zeebrugge as a base for sub- marine operations in the channel, but had to be content with occasional visits of u-boats, until the special types of small ub- and uc-boats should be ready. one objection was that zee- brugge was specially liable to air attack; u14, ready to start for attack on the transports, was damaged by aeroplane bombs and on feb. 14 returned to germany for repairs. submarines continued to pass dover strait and sink vessels in the channel and on the west coast. on march 4 the net and destroyer patrols succeeded in sinking u8, whose crew surren- dered. the admiralty refused to accept as lawful the german method of sinking ships without warning and detained these men for trial, a measure that produced such violent reprisals in ger- many that they were eventually treated as ordinary prisoners of war. wedcigen in uzg after sinking 6 vessels, one a defensively armed ship, was himself rammed on march 14 by the battleship “ dreadnought ” and drowned with all his crew. four days earlier ur2 was rammed by the destroyer “ ariel’? and sur- rendered. a third loss at this time caused special uneasiness in germany. u37, a new boat, operating in the channel, disap- peared without a trace. other boats had reported nets, mines and various obstructions in the straits; and it seemed too dan- gcrous to allow the scanty force of u-boats to run unnecessary risks. on april ro, although the army command was pressing for more intensive attack on the transports of the b.e.f., high sea fleet submarines were ordered to make their passage to and from the channel only by the north of scotland. thus the dover net had proved effective; but by the irony of fate, it was on that very date that admiral hood hauled down his flag at dover to be superseded by admiral bacon. henceforward u-boats found it so difficult 1o approach the transports route that they ceased to enter deep into the channel. the u b-boats —attack in that area was left to the little ub-boats. the first 18 of this class built specially to work from flanders, had a surface speed of only 63 knots and had as their armament at first merely two torpedoes and a few rifles. such vessels could manifestly operate only by torpedoing ships with- out revealing themselves. the first completed was ub10, but the first success fell to ub4 which on april 10 torpedoed the belgian relief ship “‘ harpalyce.”? on the r4th the dutch * katwyk ” was torpedoed without warning by one of these ub-boats near the north hinder light vessel. although nets were moored off the belgian coast and the patrols were numerous and active, these feeble little ub boats fought the tide rips and navigated amongst the sand banks of the east coast sinking ships and raid- ing the fishing fleets. on june 21, ub6 passed through the dover barrage and reconnoitred boulogne. thenceforward the dover patrol could not keep them out. the uc-boats—f¥ landers was also a base for submarine mine- layers, known as the uc class, which instead of torpedo tubes carried mine tubes containing mines. the uc-boats, no faster than the ub’s and totally unarmed, were intended only as secret minelayers. their method was to creep at night to some light vessel or buoy and lay their mines close to it. the first to reach flanders was ucir which on may 29 started for her maiden cruise to mine the south goodwin. she fouled an indicator net and was chased till she unknowingly entered a british minefield. escaping the double peril of net and mine she proceeded to her objective, and laid her field. on her second trip she was caught in another net, from which, however, she disentangled herself with- out provoking a hunt. the mines laid by the uc-boats being always on the thickly frequented east and south coast routes claimed many victims, regardless of nationality. an account of the admiralty’s method of dealing with the uc mines belongs more to mine-sweeping (q.v.). attack in the western approaches.—after april 10 u-boats operated only in the north sea and in the western approaches. in the north sea the attack was chiefly on shipping of the scan- dinavian powers, especially early in may when three of the latest submarines sank between them half a dozen danish, norwegian and swedish steamers, besides fishing vessels. germany’s plan was to keep three u-boats at work in the western approaches, 7o a scheme which employed 9g boats, 3 working, 3 on passage, 3 resting. only the best boats could reach southern ireland, where they found easy prev in the open waters between ireland and ushant. it was no part of the german intention to exempt pas- senger vessels from attack; in their announcement of feb. 4 such had been specifically mentioned as liable to danger, and several large liners were sunk. the liner “‘ falaba ”’ was torpedoed, after five minutes warning, by u28, 57 passengers being drowned; and on may 7 schwieger in u2o torpedoed the “ lusitania ” without any warning and drowned 1,198 men, women and children. the chorus of praise which in germany greeted this master- piece of the submarine war had soon to be modulated into a minor key, for among the murdered were citizens of the united states, whose president now protested against germany’s methods. two american steamers, the “ gulflight ’ and “ ne- braskan ”’ were torpedoed without warning in may; but as they both reached port, the irritation roused in the united states by their cases was swamped by the rising tide of anger over the “ lusitania.” so powerful was the feeling that the german politi- cal authorities gave way, and on june 5 issued orders that large passenger ships were to be spared unless they made deliberate attempts to injure submarines, a reservation that was to have important consequences. on aug. 1g schneider met the white star liner ‘ arabic ”’ and assuming that she intended to ram him torpedoed her without warning with the loss of 44 lives. american indignation flamed up anew. to placate it orders went out on aug. 30 that no liners were to be sunk without due regard to the safety of passengers. this was followed on sept. 20 by the total suspension of sub- marine warfare on the west coast and in the channel, in effect, the conclusion of the first submarine campaign in ilome waters. in the course of its progress the decoy ship idea had been devel- oped in three forms—a small tramp steamer with conccaled arma- ment, a trawler apparently fishing but really towing a submarine and a sailing smack with a hidden gun. none of these types of vessel was worth a torpedo, and the hope was that the enemy would come close either to fire guns or to send a party on board with bombs. the first success fell to the ‘‘ prince charles ”’ (lt. mark-wardlaw), outwardly a slovenly collier, which on july 24 destroyed u36 west of the orkneys. on the day the ‘« arabic ” was torpedoed, another decoy ship, the “ baralong,” sank u27;a month later she sank u4r1. by the towed submarine decoy u4o was torpedoed on june 23 and u23 on july 20. the armed sailing smack “ inverlyon ”’ (gunner e. m. jehan, r.n.) sank ub, on aug. i5. the first submarine campaign against merchant ships resulted in the loss of 166 british steamers and 168 british fishing vessels, the latter a class which by the hague convention should have been spared. france, russia and belgium had lost 34 ships be- tween them. but the attack was not only on belligerents; it was directed against all the nations of the world. of the neutrals, norway, having the largest mercantile marine, had suffered most; 51 norwegian ships had been sunk by submarines alone. sweden and denmark each lost 15, holland and spain 2 each. several of these neutral vessels were torpedoed by ub-boats at night without warning. these losses are exclusive of ships which struck mines; holland had suffered specially by these. spring campaign of 1916.—during the winter the naval author- ities in germany managed to wring from the political heads per- mission to torpedo defensively armed vessels without warning, though passenger ships were still to be spared; and in feb. 1916 the attack began again, many more submarines both of the u and ub classes being now ready. as before, the southwest approach was its main theatre. in the former campaign u-boats had quickly taken advantage of the admiralty’s orders that ships were to keep away from land and thus incidentally away from protection, since the auxiliary patrol was not then effective more than 40 m. from shore. but now, a new principle was adopted. as soon as a submarine was known to be present in a certain area, all outbound shipping which would pass that area was held in port until it was thought the enemy had gone away, and incoming submarine campaigns vessels were directed by wireless to hug the shore where the patrols were thickest. in the southern part of the north sea the ub-boats secured some neutral victims, notably the large dutch liner ‘“‘ tubantia,” torpedoed without warning on march 16. they also torpedoed at night several vessels at anchor off british and trench ports. particularly was this the case with havre, where store ships had frequently to wait for hours before they could be admitted to the congested harbour. as a deterrent to submarine action there the admiralty sent over a detachment of drifters, whose nets, now studded with mines, succeeded in accounting for ub26 on april 5. a fortnight earlicr the q- ship ‘ farnborough’ (comm. gordon campbell) destroyed u68, off the southwest corner of ireland. on march 24 pustkuchen in ub2g torpedoed the french packet ‘* sussex,’’ crowded with passengers for dieppe. after the “ lusitania” correspondence, germany had promised president wilson not to molest passenger ships of any national- ity and not to torpedo without warning any unarmed vessel. the promise had been disregarded from the beginning; indeed, the first vessel attacked in this second campaign, the ‘‘ arbonne,” had been torpedocd without warning and without survivor by ub2 on feb. 21; but the president first took notice of the “sussex” incident. thoroughly roused, he sent what was practically an ultimatum demanding the immediate abandon- ment of germany’s “present methods of submarine warfare against passenger and freight-carrying vessels.” the german govt. surrendered and at the end of april stopped this second campaign. between the beginning of feb. and the end of this spring campaign submarines destroyed 58 british mercantile and fishing vessels and 18 norwegians; france lost 3 steamers, and several other nations one or two apiece. autumn campaign of 1916.—throughout the summer of 1916 the u-boats with adml. scheer were employed with the fleet, and merchant ships in home waters were left alone. in july, however, the flanders submarines made a serious raid on north sea fishing vessels, sinking 47 between july 4 and aug. 6, among them the little ““ mary ann ” of 5 tons, the smallest vessel sunk by a submarine. the ub-boats sank a few other vessels, includ- ing the “ calypso,” torpedoed without warning on july 10, with a loss of 30 lives. in sept. began a continuous attack on the vessels carrying munitions to russia; between sept. 20 and oct. i6 a total of 13 norwegian, 4 russian and 3 british ships were sunk in the arctic ocean. in response, four q-ships and 3 british submarines were sent to operate on the murman coast but achieved no success, though two german submarines were de- stroyed by russian patrols. in the summer of 1916 the political situation of the allics was, perhaps, at its lowest ebb throughout the war. germany’s prompt surrender to president wilson’s ultimatum at the end of april diminished the tension across the atlantic, whereas the allied blockade was now so effective that it drew from the united states a strong protest. encouraged, doubtless, by this reversal of the situation germany decided to renew submarine warfare on commerce, theoretically in accordance with prize law. the attack was at first mainly against scandinavian shipping by which iron ore amongst other things was brought across the north sea and coal carried to france and italy. in sept. and oct. norway lost 5° of her mercantile marine. in the english chan- nel the ub-boats, now armed with guns of some size, and in the western approaches the large u-boats, did much damage; as a rule they took care to give some warning except in the case of defensively armed vessels, though the destruction of 3 vessels without warning at the end of oct. caused the drowning of 85 non-combatant seamen. the rate of sinking increased so much that adml. jellicoe took the unusual step of writing direct to the prime minister drawing his attention to the fact that the loss of shipping alone might soon cause the allies to conclude peace. as a result of the conference which followed he was appointed first sea lord to carry into effect the various proposals he made for dealing with submarines. by that time the tension between the united states and germany had been increased by the appearance submarine campaigns of us3, lt.-comm. rose, off nantucket on oct. 7. there within sight of land lt.-comm. rose sank 5 ships, 3 british, 1 dutch and t norwegian. his voyage out and back occupied 42 days. no other commerce-destroying submarine visited america in 1916; perhaps the emotions stirred by rose were not quite what was intended. in face of the severe attack on their ships, norwegian owners were inclined to keep the remainder in port; and since british munition works and the continuance of the war by france de- pended on the cargoes they carried, the position was serious. attempts were made to maintain a patrolled lane across the north sea, but between sept. 1916 and jan. 1917 inclusive, 170 norwegian, 29 swedish and 50 danish ships were destroyed by german submarines, as against 86 british sunk in home waters in the same period. one of the problems to be solved was to find some efficient metho«! of damaging a submarine when it was submerged. the explosive charge towed by a patrol vessel soon proved to be nearly useless, since it could easily be avoided; and experiments were made with bombs which could be dropped or thrown overboard. by the middle of 1916 had been evolved the “ depth charge,” a large bomb which exploded at either 40 or 80 ft. below the surface, according as set. depth charges were heavy things and had to be heaved over on to the submarine; they could, therefore, be used only at very close quarters. much was hoped from them; but it was soon apparent that unless the bomb exploded within 30 ft. or so of the submarine, it did not damage it sufficiently to bring the boat to the surface cither on account of the dislocation of its machinery or to allow the crew to escape. it was not till the following year that the depth charge, fired from a sort of howitzer, became a really formidable weapon in the hands of the anti- submarine forces, which in the autumn campaign had mainly to rely on the ram, the towed charge, the net, the mine and the gun. these effected the destruction of only three or four u-boats be- tween sept. 1915 and jan. 1917. at the end of nov. 1916 a success fell to the q-ship “‘ pens- hurst ’’ under comm, f. h. grenfell, r.n., which gives an ex- cellent illustration of the work of a decoy ship. the “‘ penshurst ” had been cruising for a year and never met a submarinc till nov. 29 1916, when she was fired on by one near the lizard. the cir- cumstances of light and range were unfavourable to the “ pens- hurst ”’ and she had to reveal her armament without making sure of her quarry, which submerged and escaped. realising that the character of his ship was now revealed, and that no submarine would approach him on the surface, grenfell returned to harbour. in the course of the night he had his ship painted in a different way and altered the appearance of her masts, so that when the ‘** penshurst ” sailed next morning the submarine commander would never suspect her of being the vessel which had opened fire on him from hidden guns. before long, the “‘ penshurst ” took in a wireless signal reporting a submarine had been sighted near guernsey. grenfell steered in that direction and soon sighted the enemy. but just then a seaplane ilew over and dropped a bomb near the submarine, making it submerge. the “ penshurst ” carried depth charges as well as guns and grenfell was about to make arrangements for dropping these when the submarine came to the surface and began to shell the ‘‘ penshurst.” this was gren- fell’s opportunity. he stopped his ship; sent away in boats all his crew but the gunners; and when the submarine approached to finish off the apparently abandoned ‘“ penshurst ” he sank her instead with his concealed guns. thus ubro met her end. six weeks later, grenfell in the ‘‘ penshurst ” destroyed ub 37, after having silently endured a gunfire which killed some of his gun’s crew and wrecked his depth-charge dropping gear. the mediterranean to jan. 1917.—i1n the mediterranean, as in the north sea, submarine operations were at first limited to military objectives, though they soon degenerated into com- merce warfare. austria had a dozen or more submarines which she used against warships, the first to suffer being the french ‘“* leon gambetta,” flagship of the adriatic patrol, sunk on april 27 i915, with the loss of 570 lives. in june the british light 671 cruiser ‘‘ dublin ” was torpedoed but did not sink. when italy joined the allies on may 23 the italian navy supplied targets for austrian submarines and before the end of july two italian surface men-of-war and an italian submarine had been sunk by the austrian u-boats. the result was that the heavy ships of the italian navy became almost entirely retained in port. a more important object for submarine attack was provided by the british and french squadrons operating in 1915 for the capture of the gallipoli peninsula. at the end of april one of the most efficient german submarine commanders, hersing in u2r, left germany for constantinople, a journey of unprecedented length. arrangements were made to supply him with oil half- way; but when he met his supply steamer he found that she had brought the wrong kind of oil and he decided to go on without it. he gave up the idea of making constantinople and proceeded instead to cattaro in the adriatic, reaching it on may 13 with only half a ton of oil left. a week later he received orders to attack the ships bombarding at the dardanelles. before the end of may ro15 he sank the battleships * triumph ” and ‘ ma- jestic ’” and entered constantinople, having dealt the distrusted dardanelles enterprise a wound from which it never recovered. germany also sent by train ub- and uc-boats in sections to be erected at pola; by the autumn u33, u34, u35, u38 and uap, the latest and best u-boats, had arrived at cattaro, bringing up the german submarine force in the mediterranean to 5 large u-boats, 4 ub-boats and 4uc-boats. three of the last class worked from constantinople, the remainder from the adriatic against mer- chant vessels. in nov. arnauld de la perri¢ere was appointed to u35 and, in spite of his french name, proved himself one of the most redoubtable german champions in the war against merchant vessels. in the mediterranean the conditions were greatly in favour of the u-boat; the clear air and smooth seas gave the man at the periscope a better chance than his colleague in home waters, peering through the mists and storms of the north sea and atlantic; moreover, the immense distance between gibraltar and malta, and between malta and suez, precluded the possibility of efficient patrol at any but a few points. all the submarine com- mander had to do was to go out on to the steamer track and pick off the ships one by one as they came up to him. if they were armed he could torpedo them without revealing himself; if un- armed they could be shelled into surrender. the only dangers he could not avoid were the very rare meetings with q-ships and the passage of the net barrage maintained after sept. 1915 by british drifters across the otranto straits in the hope of stopping ap- proach to the submarine bases in austrian waters. the protest of president wilson had no effect in the mediterranean and the sinking of merchant vessels continued without those interrup- tions which cut the hlome waters campaign into such well- defined sections. when the president was promised that sub- marines would operate in accordance with their own prize law a month or two elasped before there was any resumption in the mediterranean of the practice of torpedoing at sight. but in nov. 1915 the ‘‘ californian,” ‘‘ treneglos,” ‘‘ orange prince ” and ‘“* hallamshire”’; in dec. rg1t5 the “ persia’? and “ clan macfarlane’’; and in jan. 1916 the “ glengyle”’ were all torpedoed without warning. all were large ships, the “‘ persia ” being a p. & o. liner full of passengers; the loss of life in her case was 334. for a few months in the autumn of 1915, when it seemed pos- sible that the turks would attack egypt, the german sub- marines were employed in conveying war material to the restless tribes to the westward of the egyptian border. on one of these trips uz5 sank the patrolling british armed merchant cruiser “*tara,”’ whose crew were driven by senussi into the interior, where they subsisted on snails and such meagre provisions as their captors consented to dole out until they were rescued by the duke of westminster’s armoured cars. after the evacuation of gallip- oli peninsula, the german submarines confined themselves to attack on merchant ships. in the 18 months from hersing’s arrival to the end of jan. 1917, a total of 200 british, 189 italian and 52 french ships were destroyed in the mediterranean. 672 during this period seven austrian submarines had been de- stroyed, three by italian men-of-war, one caught in the otranto barrage, three others by unknown circumstances. several of the german ub- and uc-boats were lost from various causes; but none were destroyed by british or allied warships. the q-ship “nmargit ” had a chance of opening fire on a submarine in jan. 1916, but did not succeed in sinking it. on the whole, the medi- terranean was a safer ficld of operation for submarines than home waters. operations of british submarines in the baltic —british sub- marines had no such easy work as the german u-boats. germany sent no troops abroad, and her imports reached her from contigu- ous countries by land or in short passages across the baltic. in that sea several british submarines operated. the first was er (lt.-comm. n. f. lawrence) which passed through the sound into the baltic on oct. 17 1914. she fired two torpedoes at, but missed, a german cruiser near the entrance to niel bay and seri- ously disturbed what had been thought the security of that sea. eg (lt.-comm. max horton) arrived in the baltic two days later. after a few days in harbour the two e-boats commenced opera- tions against the german flect and though they did not succeed in sinking any ships, the knowledge of their presence brought to an end the safety with which german forces had exercised in the western baltic. the ice of the baltic winter soon kept the british submarines in harbour to wait for the spring. in may max horton torpedoed a german cruiser; in june, a destroyer and collier and in july an old cruiscr. the germans by then were making a strenuous effort to cap- ture riga. to assist in the defence the admiralty despatched e8 and er3 in august. the latter, through a breakdown of her compass ran ashore in danish territory on aug. 19, and was allowed by the danes 24 hours to endeavour to rcefloat. before this interval elapsed two german destroyers appeared and opened fire on her and on the seamen swimming from her towards the danish shore, causing the death of 15 of them. this outrage on humanity and danish sovereignty was possibly the outcome of german irritation at the interference with their plans due to the activity of our submarines; on that same day ex torpedoed the battle-cruiser ‘‘ moltke ” off the gulf of riga and sent her back to port for repairs. two days later the germans abandoned their attack on riga. in the autumn our submarines were used chietly in stopping the passage of iron ore from sweden to germany. between oct. 11 and 23 they sank 14 large german steamers loaded with ore and so effective were their operations that 37 other steamers ready to sail were held up in swedish ports till a system of convey could be organised. in nov. the old cruiser * prinz adalbert ’ was sunk by e8 and in dec. a light cruiser and a torpedo-boat were destroyed. during that autumn and winter some 20 german steamers aggregating 45,000 tons were sunk or seriously damaged by our submarines, producing a sort of paraly- sis in the transport of iron ore to germany. by july 1916 there were 8 british submarines in the baltic, 4 of the e class and 4 of the c class; commander cromie of e1g took command of this baltic flotilla, which was put under the direct orders of the russian commander-in-chief. throughout 1916 and 1917 the boats were used by him in an interminable serics of reconnaissances; they had no opportunity of interfering with the iron-ore traffic and little chance of attacking warships, since the essence of reconnaissance is that the presence of the watcher should be unsuspected. the outbreak of the revolution in russia still further limited their activities. in nov. 1917 c32 was so badly damaged in an encounter with german patrols that it was decided to destroy her and send the crew home. finally, on april 3 1918, news having been received that the germans were advancing on the submarine base at helsingfors, the whole flotilla went out to sea through the ice and was blown up by its officers. thus perished ex, 8, 9 and 19 and c26, 27 and 35. comm. cromie never returned to england; he was killed by bolsheviks on the steps of the british embassy. british submarines at the dardanelles.—the operations at the dardanelles gave opportunities for some remarkable exploits by the british submarines attached to the eastern mediterranean submarine campaigns squadron. their ability to interfere with turkish transport to the gallipoli peninsula was fully realised; but the passage of the dardanelles at first seemed impracticable. the straits are 27 m. long and for 34 of these miles they are only 1 m. wide; there, in the narrows, it was known that anti-submarine nets, booms and minefields had been placed; but the nets and booms, it was thought, might be passed by specially fitted submarines. lt. n. d. holbrook, in b11, was the first to try. he successfully negotiated the passage of the mincficlds and on dec. ri 1914 torpedoed a turkish cruiser, the “ messucich.”” on the return journey his compass became unserviceable, and to the alreadv great enough hazards of the mines and the pursuit was added the difficulty of navigating an unfamiliar channel without a compass. surviving all these perils he returned and was awarded the victoria cross. no further attempt was made till the spring of rors. in april, ers (lt.-comm. t. s. brodie) opened the campaign, but unfortunately grounded some 10 m. up the straits and was lost. strenuous efforts were made by other sub- marines, destroyers and even battleships to destroy the hull of ers so that the turks could not use her; but the activity of the defence foiled them all. it was left to one of a pair of picket boats which crept up the straits on a pitch black night to find and torpedo the wreck of e15. the ill-luck of lt.-comm. brodie did not deter his colleagues, british and french, from following. e14 (lt.-comm. e. c. boyle) sank three turkish ships, including a transport with 6,000 troops aboard; but ae2, a submarine of the australian navy, was sunk by gunfire on april 30. in may the french submarine “ joule ” struck a mine and was lost in her first attempt at the passage. ear (lt.-comm. m. e. nasmith) returning from a successful voyage found a mine sitting on his bows, but was able to get rid of it by clever manoeuvring. iic had penetrated as far as constantinople itself, where he torpedoed and sank a turkish gunboat. near rodosto he sank several transports and store ships, his nearness to shore in one case being such that he was forced to retire by a party of horsemen. he returned to con-- stantinople and torpedoed the man-of-war “‘ stambul,” in the golden horn itself. it was the first time that an enemy had appeared in that harbour since it had become turkish; and his exploit had the effect of stopping for the time all sea communi- cation between constantinople and gallipoll. exr2 (lt.-comm. k. m. bruce), e7 (lt.-comm. a. d. coch- ranc), e2 (comm. david stocks), ezo (lt.-comm. c. h. warren) and ifr (lt. wilfred pirie) also made the dithcult and dangerous passage with more or less striking results. e12 on one occasion encountered and sank a decoy which carried a masked gun. amongst other exploits lt.-comm. cochrane attacked the railway line and blocked it for a time. e14 and err were up the straits together at the end of july and sank between them some 30 ships bound for gallipoli. every possible obstacle was put in their way by the turks, who had erected a powerful barrage at nagara. the french submarine “‘ mariotte ’’ fouled a mine, and while trying to free hersclf was shelled into surrender (july 26). bruce in e42 cruised in the sca of marmora from sept. 16 to oct. 25, 40 days, during which he sank 34 ships and did much damage to magazines and railways ashore. on the way back the bows of his boat carried away part of the nagara obstruction and e12 was dragged down to a depth of 245 it. before she could gain control. the entanglement, whatever it was, was scraped off her by a chain boom a little lower down the straits and though she broke surface in her plungings and came under fire from guns and torpedoes, she managed to reach helles in safety. in nov. err and e2o and the french submarine “ tur- quoise ”? went up the dardanelles to continue the disturbance to turkish communications. only one of them returned. the “ tur- quoise ” ran aground and was captured intact. a paper found by the turks in her revealed a rendezvous, and by despatching a submarine to that spot they were able to torpedo e20. nasmith in eri cruised for 47 days in turkish waters; before returning he destroyed or rendered uscless 11 steamers and 35 sailing vessels, in face of all the barrages, patrols and batteries set up to prevent him and in spite of the fact that shipping for safcty’s sake had submarine campaigns been kept in harbour as much as possible. when the gallipoli peninsula was abandoned at the end of 1915 the necessity for running the risk of penctrating the dardanelles no longer existed and the operations of british submarines came to an end; but the record of their work will always remain an inspiring chapter in the history of the british navy. analysis of the autumn campatgn—during the autumn campaign of 1916, german submarines in home waters had been acting under some sort of restrictions as regards sparing passenger ships and refraining from torpedoing vessels without warning. these restrictions were not in accordance with admiral scheer’s ideas; his view was that the submarine as a weapon could best achieve results by surprise; and to him it seemed unreason- able to expect submarine commanders to expose themselves to the great risks known to exist if they came to the surface and warned vessels before sinking them. most large merchant ships were now armed for defence, and some had even sunk attacking submarines; and, moreover, there was always the possibility that a tramp steamer, harmless to the outward cye, might really be a q-ship, to attack which was death. only reluctantly had scheer allowed his high sea fleet submarines to participate in the autumn campaign, and he expected little good from it. the re- sults exceeded anticipation; indeed, oct. 1916 proved the worst month of the three campaigns of 1915 and 1916. in that month submarines destroyed 148,000 gross tons of british shipping and 124 foreign ships of 164,000 tons—a total of over 300,000 tons for all the nations of the world. the progress of the campaign in dec. 1916 and jan. 1917 can be seen in the following table:— destroyed by submarines dec. 1916 jan. 1917 gross tons 111,074 58,253 55,487 17,151 42,142 ships british : : i 39 gross tons 110,160 66,690 43,537 16,113 39,900 276,400 allies. ; : 53 norwegian . & “serie g2 danish , ; 17 other neutrals . ck: 21 totals 167 an interesting feature in the campaign is that the shipping of the neutral nations suffered more severely than british; in dec. 7o neutral ships to 39 british and in jan. 66 neutral to 51 british, of which 16 were small fishing craft. norway, in particular, lost nearly as many vessels as england. such favourable results of the submarine attack on merchant vessels, restricted as it was, strengthened the arguments of that party in germany who were convinced that, if all restrictions were removed, submarines could double their rate of destruction and would, in any case, bring to a standstill the norwegian traffic to england. their arguments gained the day and it was decided to carry on the submarine attack as in 1915 without restrictions. the step would probably compel the united states to break off relations; but the submarine party were confident that before america’s military forces could affect the issue of the war, it would be over, with england vanquished. so certain did this seem that germany put forward a proposal of peace, but as it was couched in terms such as a victor uses to the vanquished, it was rejected. then, on feb. 1 1917, was re-introduced the original method of unrestricted warfare. areas enclosing the british isles and france, the mediterranean and, later, the portuguese atlantic islands and the area round archangel, were declared war zones; vessels of any nationality or character found in the war zones would be destroyed, and though no special efforts would be made to kill the crews, consideration for the safety of their lives would not be allowed to hinder the submarines in their work. til. the final struggle second “ unrestricied”’ campaign, feb. 1917 to nov. 1918.— to carry on the unrestricted campaign germany had 111 sea- going submarines of the u, ub and uc classes, though the uc- boats were still primarily minelayers whose operations are treated elsewhere (see minelaying), they now carried guns and 673 a few torpedoes and could therefore wage war on merchant vessels in the same way as the other classes of boats. attached to the ifigh sea fleet there were 29 submarines active and 20 under repair, the figures for the other stations being: landers 31 and 2; baltic o and 2; adriatic 7 and 17; constantinople 2 and 1; a total of 69 at work and 42 under repair. the declaration of unrestricted warfare, which meant that neutral vessels would again be sunk without warning, had a serious effect on the departure of ships from scandinavian countries. this had been foreseen by the british admiralty and. was countered by the detention of each scandinavian ship already in british ports until it was known that a corresponding vessel had sailed for england. even with the reduction of traffic at sea resulting from the natural reluctance of non-belligerents to take the risk of entering the war zones the losses were:— february march april ships | gross tons; ships | gross tons| ships | gross tons british allies neutral 260,000 77,000 132,000 287,000 115,000 122,000 469,000 524,000 the rate of increase in losses was such that it seemed that the submarines would win the war for germany. they were being completed faster than they were being destroyed so that their number increased from 111 on feb. 10 to 127 on april ro. it was clear that the existing methods of fighting them were in- sufficient. though all the forms of defence—detaining ships in harbour when a submarine was known to be about, causing ships to hug the shore, sending q-ships on the traffic routes, arming more and more merchant ships, patrolling the avenues of approach—and all the weapons of attack, such as depth charges and hydrophones, were made more and more efficient they could not stay the tide of devastation. on april 19, the worst day for england of that worst month, 11 british merchantmen and 8 fishing vessels were sunk by submarines; and it has been stated that one out of every four vessels that left great britain in that month never returned. there were few successes during these first three months of the unrestricted campaign to hearten the defence; 2 ub-boats from zeebrugge stranded on the dutch coast, one uc-boat was blown up by mines off sunderland, two british submarines torpedoed german boats, a destroyer ‘‘ depth- charged ” uc39, and captain gordon campbell in the q-ship “farnborough ” got u8s after an action which so nearly meant the loss of his ship and her gallant crew that he sent by wireless to admiral bayly at queenstown the famous signal “ q5 slowly sinking respectfully wishes you good-bye.” it is satisfactory to know that she did not sink and that captain gordon campbell survived to be the hero of a service manned by heroes. one episode of these terrible three months remained unique; the british submarine eso, proceeding under water, rammed a ger- man boat also submerged, bringing into the realm of fact one of jules verne’s most lurid fancies. ‘though she struck the german craft three separate blows, 1t escaped to tell the tale of one more peril for the u-boat. escorted convoys.—nevertheless, the submarine was winning. unless some new and effective device could be put into action the surrender of the allies was in sight. but the device was on the point of adoption. scandinavian vessels refused to sail with- out escort and since it was impossible to escort each singly, they were gathered into convoys guarded by such armed vessels as could be spared. ‘the principle of escorting a convoy had been in force for some months with the trade between holland and eng- land, and with the continuous export of coal to france, which being carried in slow vessels could be accompanied by armed trawlers; but the difficulties in escorting an ocean convoy had been considered too great for the means at our disposal. when at last the method was tried, these dificultics were found to have been over-estimated, and gradually the gathering of merchant vessels inlo escorted convoys became general. special schools were established to train the masters of ships in the complicated 674 manoeuvres of zigzagging in squadrons and a large organisation came into being to collect each convoy and its escort. between march and aug. 8,000 colliers crossed the channel to france in groups under some sort of escort and only 14 of them were lost. ln proportion as the convoy system became universal so did losses diminish. in may submarines sank 303 vessels of all nationalities totalling 550,000 tons; by nov. the totals had fallen to 116 and 259,000 tons. of 6,000 vessels convoved between norway and the humber the loss by submarine action was 1 °%. one reason for this marked diminution was that now the u-boat had to run into danger to secure any prey. before the intro- duction of convoy the submarine, by eluding the patrols, could deal with ships at leisure; but now she could not approach the bait without running the chance of being hooked. an ingenious sys- tem of dazzle painting was introduced and a convoy appeared in a periscope as a shapeless mass of stripes and blurs continually altering as the ships zigzagged; the escorting destroyers and trawlers forced a watching submarine to keep its distance, and its best chance was to catch a straggler. but this again was not infrequently a q-ship, masquerading as a lame duck to invite attack. as the losses in shipping diminished the rate of de- struction of submarines increased; in april, may and june of 1917 12 boats; in the next three months 20; and in the last quarter of 1917, 24 boats. to comm. maurice blackwood in the q-ship ‘**stonecrop ”’ fell a special prize in sept. when by admirable coolness and cunning he entrapped and sank u88. the “ stone- crop ” was sunk next day by another submarine; but in u88, which disappeared with all hands, was the notorious schwieger, who two years before had sunk the “ lusitania ” and forced the united states to consider the possibility of joining the allies. the united states declared war in april 1917 and before the end of the year had sent 37 destroyers to assist in convoy work. one of these destroyers, the “‘ fanning ” while on convoy duty in nov. 1917 dropped a depth charge on us58 and forced her to surrender. this was the only submarine known to have been destroyed by the united states forces. even with the addition of the united states destroyers it was not possrble to escort every vessel, and on some routes merchant ships had still to fight for themselves. a curious fate overtook u28 in september. she met a vessel making for archangel with ammunition; she first torpedoed it and then came close to sink it by gunfire. her second shot burst among the ammunition, and the terrific explosion which resulted wrecked the submarine. u28 disappeared forever, jeaving her men struggling in the water. another archangel steamer, armed for defence, fought a duel with a submarine till dusk without a decision. the sub- marine followed, intending to torpedo the ship in the darkness. she crept up on the quarter and fired two torpedoes; but the wary skipper, hearing an unusual noise, put his helm hard over and saw the white track of the torpedoes pass along his ship’s side. half an hour later he observed a luminous patch ahead of him and stecring for it had the satisfaction of ramming his pursuer and ending her career. the submarine was u4g; the steamer, the “ british transport.” every type of vessel contributed to swell the number of lost submarines. in april 1918, motor launch no. 413, a vessel of a type built specially to deal with submarines, was on patrol in the western mediterranean, with her hydrophone out listening for the sound of a submarine’s propeller. one was heard; and in the dim light of dawn, it could be seen rapidly approaching till it passed across the bows of m413. sceing the motor launch it submerged, but ml413 followed the wake and continuing along it and in the same direction till she was 150 it. ahead of it she dropped four depth charges. the humming of the submarine’s propeller instantly ceased. at daylight pieces of wood were seen floating, one a large fragment of varnished mahogany with steel hinges, undoubtedly part of a door from the interior of the submarine. the depth charges had been well aimed; they had torn the submarine to pieces. later it was proved that this was ub7r. the attack defeated.—as 1917 progressed it became increas- ingly clear that the submarine attack on merchant vessels had submarine campaigns been countered. the number of submarines in commission reached its maximum of 140 in oct. and then slowly diminished. they failed to impede either the transport of british troops to france or of american troops to europe. only one transport of the latter, the “‘ tuscania,’”? was torpedoed, and in her case the loss of life was 44. although four of the best u-boats were sent across the atlantic specially to attack troop transports, and they destroyed 60 ships between them, not one contained troops. moreover, one of the submarines, urs56, was lost in the great minefield laid across the north sea. throughout the war the british had made efforts to mine the exits from submarine bases and the entrance to the english channel. they were ineffectual, owing mainly to the defects of the british mine. the advent of america into the war gave us access to her factories; and a newly designed mine, produced in immense quantities, made it possible to close heligoland bight from time to time and to make the straits of dover absolutely impassable. a similar barrage was established across otranto straits; and sinkings in the mediterranean, where they had been specially heavy, began to diminish. by the end of the summer of 1918 it was obvious to the german authorities that the submarine campaign could not be a success; and when the land operations also failed, the flanders bases were evacuated, and the submarines there were blown up—all except one, ub116, whose commander, lieutenant emsmann, made one last effort. he reached the entrance to scapa flow on oct. 28, but the search-light picked him up and his boat was sunk in the very gates of his enemies. the armistice terms included the surrender of all german submarines. one hundred and thirty-eight still remained and these came in to harwich. one hundred and ninety-two had been destroyed and seven interned. in addition, + austrian submarines had been destroyed. an analysis of the methods of attack shows that the destroyers and patrol vessels with their guns, depth charges and rams accounted for 64 boats; mines and mine nets destroyed 43; british submarines torpedoed 18; q-ships sank 11. the cause of loss of 19 is unknown; the re- mainder met their end from various weapons. — in view of certain controversies, it 1s of interest to record that no ** dreadnought ” was sunk by a submarine, while u29 was rammed and sunk by h.m.s. “ dreadnought ” herself. of the submarine commanders, arnauld de la verriere is credited in germany with having destroyed 400,000 tons of shipping in io voyages; forstmann in u39 with 380,000 in 16 voyages; and max valentiner with 300,000 in 17 voyages. these were all in the mediterranean where conditions were specially favourable. a more dangerous career was that of steinbrinck who in 24 voy- ages is claimed to have sunk 210,000 tons. he was operating from flanders in ub- and uc-boats and had to overcome every ob- stacle that ingenuity could devise and, moreover, had to navigate among the tide-rips and shoals of the channel and the east coast of england in boats of feeble engine power. perhaps the most indefensible outrage perpetrated by the submarine commanders was the torpcedoing by patrig in u86 of the hospital ship *‘ llan- dovery castle” on june 27 1918. the vessel was unmistakably a hospital ship marked with all the signs which should secure international immunity; she was 116 m. from land; but he sank her, and drowned 14 nurses and 226 other persons, only one boatload being saved. conclusion.—\\low near did the submarine campaign approach its object of reducing seagoing tonnage below the irreducible limit necessary for the needs of the allies? one cause of the ferocity with which it was waged was the hope of terrorising merchant seamen into refusal to sail. this hope was from the first vain. the experiences of seamen whose ships had been sunk, instead of frightening them, stirred up rather their fighting spirit. when admiral jellicoe visited the crystal palace in 1918 he found there a number of merchant seamen at gun drill. most of them had had their ships torpedoed under them. one, a steward, had suffered thus four times; he was learning to shoot so that he might sink a submarine with his own hand. as regards the destruction of tonnage trading with the allies, so long as it exceeded by as much as 600,000 tons a month all replacement by suchow—sudan, building, the campaign would most probably have brought the war to a close with germany as victor. the figure of 600,000 tons net loss was perhaps exceeded in some of the months of the first half of 1917; thenceforward it fell, till in the summer of 1918 the rate of output of new shipping far exceeded the rate of de- struction. the submarine campaign against merchant shipping was a bold experiment carried out, after some hesitations, with ruthless thoroughness. it failed. it strewed around the british isles a rampart of broken hulls and the bones of gallant men. its record is mostly the sordid story of armed men against the de- fenceless; but everywhere in the gloom shine out deeds that will stir the hearts of men so long as they admire courage dauntless and sustained. table-1, ships and tonnage sunk by submarines, 1917-8 -a=number of british and allied merchant ships and fishing vessels sunk by submarines. b = number of neutral merchant ships sunk by submarines. c =total gross tonnage in thousands of tons. id = number of german submarines sunk. i9i7 1918 a b c d a b c d jan 96 65 293 2 112 19 299 9 feb i7i 66 468 4 104 19 316 4 mar. 204 85 sii 4 147 25 229 5 april 277'| tis 840 2 96 i2 262 6 may 192 89 551 6 108 18 291 17 june 211 81 633 4 vit 22 241 3 july i7i 56 495 6 83 24 260 6 aug 149 | 33 490 4 84 30 | 272 6 sept 137 18 316 10 65 181 9 oct 134] 19 42 8 4! 9 107 | 19 nov 95 at 260 9 ee 4 dec. 123 28 353 7 ae totals | 1,960 earle. 1 british, allied and neutral vessels sunk by submarines 1914-5 | 1916 1917 1918 | ° (10 months) british merchant vessels 231 288 1,052 527 british fishing vessels 168 134 200 76 allied merchant vessels. 76 344 708 314 neutral merchant vessels 93 332 79 186 totals . 568 1,098 | 2,639 1,103 grand total, 5,408 ships;
