The reader may well ask what connection these remarks have with the subject of the blocking operation. A very close connection indeed.

Napoleon—perhaps the greatest student of war and certainly one of the greatest generals that the world has seen—remarked, and repeated again and again, that in war "the moral is to the physical as three is to one." Every great leader understands the value of morale and every man who has served his country in war has at least a subconscious realisation of the moral factor.

Just consider the moral effect of the German inactivity. In our men the uppermost feelings towards the enemy were those of contempt. There is small need to consider the morale of the High Seas Fleet, for is it not recorded by their own Admiral, von Scheer, that the men mutinied at the last because they believed they were being sent out to fight our fleet? Take the case of our Dover Patrol force. They knew that the enemy could choose their own time for dashing out of the Belgian ports to attack our cross-channel communications. They knew that the chances of intercepting such enemy under adverse conditions, such as during darkness or fog, were very small. Yet month after month passed by and the enemy surface craft did next to nothing. Sometimes our advanced patrols came into touch with enemy patrols. On each occasion, I believe almost without exception, the enemy craft turned and ran at utmost speed for home. In the case of our small motor boats there had been meetings with those of the enemy within a mile or two of the latter's bases: here again, there is no recorded instance of one, or even two, of their craft standing up to one of ours. The reader will understand the resultant moral effect. Some day perhaps we shall hear the romantic story of these adventurous small craft working from the Dover area—how one of them coolly steamed in underneath Ostende Pier one night to repair her engine whilst the German sentries paraded up and down just overhead, how another ran in behind Zeebrugge Mole in broad daylight and fired her torpedoes at German vessels berthed alongside, and so on. Is it difficult to imagine the feeling of superiority and confidence possessed by our personnel?

German Morale

The morale of the German naval forces in Flanders concerned us much more closely than that of the High Seas Fleet. Under ordinary circumstances we should have been exceedingly apprehensive of any German torpedo craft at Zeebrugge or in the vicinity, especially those at Blankenberghe, but experience had served to show that they were none too ready to further the "über" portion of "Deutschland über Alles." Thus we were all the more ready to take risks which may have seemed to be uncommonly close to the border-line between "justifiable" and the reverse.

In recounting the preparations which followed naturally upon the main considerations connected with the problem in hand there has been a certain amount of unavoidable anticipation.

It has already been explained that the conduct of the operation fell to the Vice-Admiral commanding the Dover Patrol, and that a very large number of vessels of various classes and many specially trained personnel were required. Thus the fitting out of the vessels, the preparation of material, and the training of the personnel also came under the direction of the Vice-Admiral.

It must not be forgotten that the ordinary work of the Dover Patrol could not be interrupted even for one day at this period. The lines of communication across the Channel, important as they had already been throughout the war, were now of such vital importance that the Allied situation on the main battle front depended on the work of the Dover Patrol more than ever before. During February and March, 1918, when the preparations for our enterprise were in full swing, and especially during the latter month, the Germans were concentrating every possible effort to break down the Allied resistance. Their final great "push" was in full swing and the Allied troops were being hard pressed almost to the point of giving way. British, Colonial, and American reënforcements were being poured into France by every available route; guns, ammunition, and stores were passing across the Channel in an endless stream of shipping. The situation was critical to a degree. If the Dover Patrol force had failed at such a time the war might have had a very different ending. And in the midst of this terribly anxious period we were forced to request great additional effort for the purposes which the author is endeavouring to describe.
