Submarine Warfare of To-day.

INTRODUCTION

WHILE Great Britain remains an island, with dominion over palm and pine, it is to the sea that her four hundred millions of people must look for the key to all that has been achieved in the past and all that the future promises in the quickening dawn of a new era.

Not only over Great Britain alone, however, does the ocean cast its spell, for it is the free highway of the world, sailed by the ships of all nations, without other hindrances than those of stormy nature, and navigated without restriction from pole to pole by the seamen of all races. It was the international meeting-place, where ensigns were "dipped" in friendly greeting, and since the dawn of history there has been a freemasonry of the sea which knew no distinction of nation or creed.

When the call of humanity boomed across the dark, storm-tossed waters the answer came readily from beneath whatever flag the sound was heard.

But in August, 1914, there came a change, so dramatic, so sudden, that maritime nations were stunned. Germany, in an excess of war fever, broke the sea laws, and laughed while women and children drowned. Crime followed crime, and the great voice of the Republican West protested in unison with that of the Imperial East. Still the Black Eagle laughed as it flew far and wide, carrying death to whomsoever came within its shadow, regardless of race and s.e.x.

But there was an avenger upon the seas, one who had been rocked in its cradle from time immemorial, and to whom the world appealed to save the lives of their seamen. It sailed beneath the White Ensign and the Blue, and with aid from France, Italy and j.a.pan it fought by day and by night, in winter gale and snow, and in summer heat and fog, in torrid zone and regions of perpetual ice to free the seas of the traitorous monster who had, in the twentieth century, hoisted the black flag of piracy and murder. For three years this ceaseless war was waged, and then, with her wonderful patience exhausted, the great sister nation of the mother tongue joined her fleets and armies with those of the battle-worn Allies and peace came to a long-suffering world.

In that abyss of war there was romance sufficient for many generations of novelists and historians. Many were the epic fights, unimportant in themselves, but which need only a Kingsley or a Stevenson to make them famous for all time. So with the happenings to be described in this book, many of them historically unimportant compared with the epoch-making events of which they formed a decimal part, but told in plain words; just records of romance on England's sea frontier in the years 1914-1918.

Although jealous of any encroachment on the s.p.a.ce available for the description of guerrilla war at sea, there are many things which must first be said regarding the organisation and training of what may appropriately be termed the "New Navy," which took the sea to combat the submarine and the mine; also of the novel weapons devised amid the whirl of war for their use, protection and offensive power. Into this brief recital of the events leading to the real thing an endeavour will be made to infuse the life and local colour, which, however, would be more appropriate in a personal narrative than in a general description of anti-submarine warfare of to-day, but without which much that is essential could not be written without dire risk of tiring the reader before the first few chapters had been pa.s.sed.

The names of places and ships have necessarily been changed to avoid anything of a personal character, and all references to existing or dead officers and men have been rigidly excluded as objectionable and unnecessary in a book dealing entirely with events.

Many of the incidents described--written while the events stood out in clear, mental perspective--could no doubt be duplicated and easily surpa.s.sed by many whose fortunes took them into zones of sea war during the historic years just past. If such is found to be the case, then the object of this book has been accomplished, for it sets out to tell, not of great epoch-making events, but of the organisation, men, ships, weapons and ordinary incidents of life in what, for lack of a better term, has been called the "New Navy"--a production of the World War.

It may be that an apology is due for placing yet another war book before a war-weary public, but an effort has been made to make of the following chapters _a record of British maritime achievement_, more than a narrative of sea fighting, although to do this without introducing the human element, the arduous nature of the work, the monotony, the danger and, finally, the compensating moments of excitement would have been to falsify the account and belittle the achievement.

There are many books available, full of exciting stories of sea and land war, but no other, so far as the Author knows, which describes in detail and in plain phraseology those important "little things"--liable to be overlooked amid the whirl of war--which go to make an anti-submarine personnel, fleet and base, together with an account of "how it was done."

SUBMARINE WARFARE

OF TO-DAY

CHAPTER I

THE TASK OF THE ALLIED NAVIES

THE hour was that of the Allies' greatest need--the last months of the year 1914. On that fateful 4th August the British navy was concentrated in the North Sea, and the chance for a surprise attack by the German fleet, or an invasion of England by the Kaiser's armies, vanished for ever, and with this one chance went also all reasonable possibility of a crushing German victory.

Although during the years of bitter warfare which followed this silent _coup de main_ the German fleet many times showed signs of awakening ambition, it did not, after Jutland, dare to thrust even its vanguard far into the open sea. Behind its forts, mines and submarines it waited, growing weaker with the dry-rot of inaction, for the chance that fickle Fortune might place a single unit of the Allied fleet within easy reach of its whole mailed-fist.

With a great and modern fleet--the second strongest in the world--awaiting its chance less than twenty hours' steam from the coast of Great Britain, it quickly became evident that the old Mistress of the Seas would have to call upon her islanders to supply a "new navy" to scour the oceans while her main battle squadrons waited and watched for the second Trafalgar.

Faced, then, with the problem of a long blockade, a powerful fleet in readiness to strike at any weak or unduly exposed point of land or squadron, and with similar problems on a decreasing scale imposed by Austria in the Adriatic and by Turkey behind the Dardanelles, the work of the main battle fleets became well defined by the commonest laws of naval strategy.

All this without taking into account the widespread menace of submarines and mines, and, in the earlier stages of the war, the rounding-up of detached enemy squadrons, such as that under Von Spee in South American waters, and the protection of the transport and food ships from raiders like the _Wolfe_ and the _Moewe_.

The German High Command realised this as quickly as that of the Allies.

Their oversea commerce was strangled within a few days of the Declaration of War with Great Britain, and their fleet was confined to harbour, with the exception of occasional operations against Russia in the Baltic. From the German standpoint the naval problem resolved itself into one of how best to strike at the lines of communication of the Allies, paying special attention, first, to the transport of troops, and, second, to England's food supply. As they alone knew to what extent they would violate the laws of war and of humanity, it became apparent that the submarine and the mine were the only possible weapons which could be used for this purpose in face of the superior fleets of the Allies. But the number of these weapons was strictly limited compared with the immense shipping resources at the command of the Western Powers, so one submarine must do the work of many, and an effort was made to accomplish this by a reign of sea terrorism and inhuman conduct unparalleled in the history of the world. It opened with the sinking of the _Lusitania_.

The Allies had secured and maintained the command of the sea, and _all that it implies_, but to do this with the certainty of correct strategy they had to dedicate almost their entire battle fleet to the purpose for which battle fleets have always been intended--the checkmating or annihilation of the opposing navy.

There came a second problem, however, one entirely new to sea warfare, and unconsidered or provided against in its strategic and tactical entirety because hitherto deemed too inhuman for modern war. This was the ruthless use of armed submarines against unarmed pa.s.senger and merchant ships, and the scattering broadcast over the seas, regardless of the lives and property of neutrals, of thousands of explosive mines.

The type of ship constructed exclusively for open sea warfare against surface adversaries was not the best answer to the submarine. The blockading of the hostile surface fleet did not prevent, or even greatly hinder, the free pa.s.sage of submarine flotillas, and the building by Germany of under-water mine-layers enabled fields of these weapons to be laid anywhere within the carrier's radius of action.

In this way the second, or submarine, phase of the naval war opened, and it was to supplement the comparatively few fast destroyers and other suitable ships which could be spared from the main fleets that the "new navy" was formed.

THE SHIPS

The area of the North Sea alone exceeds 140,000 square miles, and when the whole vast stretch of water encompa.s.sed by what was known as the radius of action of hostile submarines, from their bases on the German, Belgian, Austrian, Turkish and Bulgarian coasts, had to be considered as a possible zone of operations for German and Austrian under-water flotillas, much of the water surface of the world was included. Likewise the network of sea communications on which the Allies depended for the maintenance of essential transport and communication comprised the pathways of the seven seas. To patrol all these routes adequately, and to guard the food and troop ships, hastening in large numbers to the aid of the Motherland from the most distant corners of the earth; to protect the 1500 miles sea frontier of the British Isles; to give timely aid to sinking or hard-pressed units of the mercantile fleet; to hound the submarine from the under-seas and to sweep clear, almost weekly, several thousand square miles of sea, from Belle Isle to Cape Town and the Orkneys to Colombo, required ships, not in tens, but in thousands. To find these in an incredibly short s.p.a.ce of time became the primary naval need of the moment.

Who that lived through those days will forget the struggle to supply ships and guns? The searching of every harbour for craft, from motor boats to old-time sailing-ships, and from fishing craft to liners. The scouring of the Dominions and Colonies. How blessed was their aid! Help, generous and spontaneous, came from all quarters, including the most unexpected. Over five hundred fast patrol boats, or motor launches, in less than twelve months from Canada and America. Guns from j.a.pan.

Coasting steamers from India, Australia, New Zealand and South Africa.

Seaplanes from the Crown Colonies. Rifles from Canada. Machine guns from the United States. Ambulances from English and Colonial women's leagues.

In fact, contributions to the "new navy" from all corners of the earth.

To patrol the coasts of Britain alone, and to keep its harbours and coastal trade routes clear of mines, needed over 3500 ships, with at least an equal number of guns, 30,000 rifles and revolvers, and millions of sh.e.l.ls.

In addition to this huge fleet other smaller squadrons were required for the Mediterranean, the Suez Ca.n.a.l and Red Sea, the East and West Indies, the coasts of the Dominions and Colonies, and for the Russian lines of communication in the White Sea. For these oversea bases just under 1000 ships were required, exclusive of those locally supplied by the Dominions and Colonies themselves.

All this without considering the main battle fleets or, in fact, any portion of the regular navy, and the ships required for the transport of food, troops and munitions of war, together with their escorts. Some idea of the numbers engaged in keeping the Allies supplied with the diverse necessities of life and war may be gathered from the fact that the average sailings in and out of the harbours of the United Kingdom alone during the four years of war amounted to over 1200 a week.

The immense fleet forming the new navy was not h.o.m.ogeneous in design, power, appearance or, in fact, in anything except the spirit of the personnel and the flag beneath which they fought--and alas! nearly 4000 died. The squadrons, or units, as they were called, consisted of fine steam yachts, liners from the ocean trade routes, st.u.r.dy sea tramps, deep-sea trawlers, oilers, colliers, drifters, paddle steamers, and the more uniform and specially built fighting sloops, whalers, motor launches and coastal motor boats. The latter type of craft was aided by its great speed, nearly fifty miles an hour; but more about these ships and their curious armament later.

WAR BASES

The great auxiliary navy had to be built or obtained without depleting the ordinary mercantile fleets, and the shipbuilding and repairing yards, even in the smallest sea and river ports, worked day and night.

The triumph was as wonderful as it was speedy. In less than fifteen months from August, 1914, the new navy was a gigantic force, and its operations extended from the Arctic Sea to the Equator. All units were armed, manned and linked up by wireless and a common cause.

Before this could be accomplished, however, the problem of maintaining this vast fleet and adequately controlling its operations had to be faced and overcome. The seas adjacent to the coasts of the United Kingdom, the Mediterranean Littoral and Colonial waters were divided into "patrol areas" on special secret charts, and each "area" had its own naval base, with harbour, stores, repairing and docking facilities, intelligence centre, wireless and signal stations, reserve of officers and men, social headquarters, workshops and medical department.

Each base was under the command of an admiral and staff, many of the former returning to duty, after several years of well-earned rest, as captains and commodores, with salaries commensurate with their reduced rank. Their staffs consisted of some six to twelve officers of the new navy, with possibly one or two from the "pukka service," and their command often extended over many hundreds of square miles of submarine and mine infested sea.

Of these bases, which will be fully described in later chapters, there were about fifty, excluding the great dockyards and fleet headquarters, but inclusive of those situated overseas. When it is considered what a war base needs to make it an efficient rendezvous for some hundreds of ships and thousands of men, some idea of the gigantic task of organisation which their establishment, often in poorly equipped harbours and distant islands, required, not only in the first instance, but also with regard to maintenance and supplies, will be realised, perhaps, however, more fully when it is stated that the average ship needs a month spent in docking and overhauling at least once a year, and that the delicate and more speedy units of such a fleet need nearly four times that amount of attention.

HEADQUARTERS STAFF

One of the first requisites of the auxiliary navy was the creation of a headquarters staff at the Admiralty, London. This was formed from naval officers of experience both in the regular service and in the two reserves (R.N.R. and R.N.V.R.).

Forming an integral part of the great British or Allied armada, all operations were under the control of the Naval War Staff, but for purposes of more detailed organisation and administration additional departments were created which exercised direct jurisdiction over their respective fleets. The princ.i.p.al of these was known as the "Auxiliary Patrol Office," under the Fourth Sea Lord and the Department of the Director of Minesweeping. These formed a part of the General Staff--if a military term is permissible--and both issued official publications periodically throughout the war, which served to keep the staffs of all the different war bases and the commanding officers of the thousands of ships informed as to current movements and ruses of the enemy.
