or as criticisms of others who, in the years before the war or during the war, were responsible for the administration of the Navy. In anticipation of such an attitude, I wish to state emphatically that, where mention is made of apparent shortcomings or of action which, judged by results, did not seem, to meet a particular situation, this is done solely in order that on any future occasion of a similar character—and may the day be long postponed—the nation may profit by experience.
Those who are inclined to indulge in criticism should ever bear in mind that the Navy was faced with problems which were never foreseen, and could not have been foreseen, by anyone in this country. Who, for instance, would have ever had the temerity to predict that the Navy, confronted by the second greatest Naval Power in the world, would be called upon to maintain free communications across the Channel for many months until the months became years, in face of the naval forces of the enemy established on the Belgian coast, passing millions of men across in safety, as well as vast quantities of stores and munitions? Who would have prophesied that the Navy would have to safeguard the passage of hundreds of thousands of troops from the Dominions to Europe, as well as the movement of tens of thousands of labourers from China and elsewhere? Or who, moreover, would have been believed had he stated that the Navy would be required to keep open the sea communications of huge armies in Macedonia, Egypt, Palestine, Mesopotamia and East Africa, against attack by surface vessels, submarines and mines, whilst at the same time protecting the merchant shipping of ourselves, our Allies, and neutral Powers against similar perils, and assisting to ensure the safety of the troops of the United States when they, in due course, were brought across the Atlantic? Compare those varied tasks with the comparatively modest duties which in pre-war days were generally assigned to the Navy, and it will be seen how much there may be to learn of the lessons of experience, and how sparing we should be of criticism. Wisdom distilled from events which were unforeseeable should find expression not in criticisms of those who did their duty to the best of their ability, but in the taking of wise precautions for the future.
Little mention is made in this volume of the work of the Grand Fleet during the year 1917, but, although that Fleet had no opportunity of showing its fighting power, it must never be forgotten that without the Grand Fleet, under the distinguished officer who succeeded me as Commander-in-Chief at the end of 1916, all effort would have been of no avail, since every operation by sea, as well as by land, was carried out under the sure protecting shield of that Fleet, which the enemy could not face.
I am conscious of many shortcomings in the book, but it may prove of interest to those who desire to know something of the measures which gradually wore down the German submarine effort, and, at any rate, it is the only record likely to be available in the near future of the work of fighting the submarines in 1917.

CHAPTER I
ADMIRALTY ORGANIZATION; THE CHANGES IN 1917
It is perhaps as well that the nation generally remained to a great extent unconscious of the extreme gravity of the situation which developed during the Great War, when the Germans were sinking an increasing volume of merchant tonnage week by week. The people of this country as a whole rose superior to many disheartening events and never lost their sure belief in final victory, but full knowledge of the supreme crisis in our history might have tended to undermine in some quarters that confidence in victory which it was essential should be maintained, and, in any event, the facts could not be disclosed without benefiting the enemy. But the position at times was undoubtedly extremely serious.
At the opening of the war we possessed approximately half the merchant tonnage of the world, but experience during the early part of the struggle revealed that we had not a single ship too many for the great and increasing oversea military liabilities which we were steadily incurring, over and above the responsibility of bringing to these shores the greater part of the food for a population of forty-five million people, as well as nearly all the raw materials which were essential for the manufacture of munitions. The whole of our war efforts, ashore as well as afloat, depended first and last on an adequate volume of merchant shipping.
It is small wonder, therefore, that those who watched from day to day the increasing toll which the enemy took of the country's sea-carrying power, were sometimes filled with deep concern for the future. Particularly was this the case during the early months of unrestricted submarine warfare in 1917. For if the menace had not been mastered to a considerable extent, and that speedily, not only would the victory of the Allies have been imperilled, but this country would have been brought face to face with conditions approaching starvation. In pre-war days the possibility of these islands being blockaded was frequently discussed; but during the dark days of the unrestricted submarine campaign there was ample excuse for those with imagination to picture the implication of events which were happening from week to week. The memories of those days are already becoming somewhat dim, and as a matter of history and a guide to the future, it is perhaps well that some account should be given, however inadequate, of the dangers which confronted the country and of the means which were adopted to avert the worst consequences of the enemy's campaign without ceasing to exert the increasing pressure of our sea power upon his fighting efficiency, and without diminishing our military efforts overseas.
The latter points were of great importance. It was always necessary to keep the Grand Fleet at a strength that would ensure its instant readiness to move in waters which might be infested by submarines in large numbers should the Germans decide upon some operation by the High Sea Fleet. The possibility of action between the fleets necessitated the maintenance of very strong destroyer forces with the Grand Fleet.
Similarly our oversea military expeditions, with the consequent large number of merchant ships in use as transports or supply ships, required a considerable force of destroyers and other small craft. These commitments greatly reduced the means at our disposal for dealing with the hostile submarines that were attempting to prevent the import of food and raw materials into the country.
Readers of books, and particularly books dealing with war, show a natural avidity for what may be described as the human side of a contest as well as for the dramatic events. But, whether it be prosecuted by sea or by land, war is largely a matter of efficient and adequate organization. It is a common saying that we muddle through our wars, but we could not afford to muddle in face of the threat which the enemy's unrestricted submarine campaign represented. It is impossible, therefore, to approach the history of the successful efforts made by sea to overcome this menace without describing in some detail the work of organization which was carried out at the Admiralty in order to enable the Fleet to fulfil its new mission. In effect those responsible for the naval policy of the country conducted two wars simultaneously, the one on the surface, and the other under the surface. The strategy, tactics and weapons which were appropriate to the former, were to a large extent useless in the contest against mines and submarines which the enemy employed with the utmost persistency and no little ingenuity. Even in the Russo-Japanese war, where the mine was little used, it exerted a marked influence on the course of the war; the Germans based their hopes of victory in the early days of the struggle entirely on a war of attrition, waged against men-of-war, as well as merchant ships. The submarine, which was thrown into the struggle in increasing numbers, represented an entirely new development, for the submarine is a vessel which can travel unseen beneath the water and, while still unseen, except for a possible momentary glimpse of a few inches of periscope, can launch a torpedo at long or short range and with deadly accuracy. In these circumstances it became imperative to organize the Admiralty administration to meet new needs, and to press into the service of the central administration a large number of officers charged with the sole duty of studying the new forms of warfare which the enemy had adopted and of evolving with scientific assistance novel methods of defeating his tactics.
Whilst the enemy's campaign against merchant shipping always gave rise to anxiety, there were certain periods of greatly increased activity. During the summer months of 1916 the losses from submarine attack and from submarine-laid mines were comparatively slight, and, in fact, less than during the latter half of 1915, but in the autumn of 1916 they assumed very serious proportions.
