With the High Sea Fleet, though several notable units were added to its strength during the last two years of the war, in every other respect it deteriorated steadily from Jutland right down to the mutinies which were the forerunners of the great surrender. This was due, far more than to anything else, to the fact that the real hopelessness of opposing the Grand Fleet in a give-and-take fight began to sink home to the Germans from the moment the first opening salvoes of the latter smothered the helpless and disorganized units of the High Sea Fleet in that last half-hour before the shifting North Sea mists and the deepening twilight saved them from the annihilation they had invited in trying to destroy Beatty's battle-cruisers before Jellicoe arrived. What the most of their higher officers had always known, the men knew from that day on, and, cowed by that knowledge, were never willing to go into battle again. From what I gathered from a number of sources I have no hesitation in affirming that, up to Jutland, the men of the High Sea Fleet would have taken it out in the full knowledge that it was to meet the massed naval might of Britain, and, moreover, that they would have gone into action confidently and bravely, just as they did at Jutland. But it is equally clear that, after Jutland, any move which the men themselves knew was likely to bring them into action with the British battle fleet would instantly have precipitated the same kind of revolt as that which started at Kiel last November and culminated in the surrender. It was the increasing "jumpiness" of the men, causing them to suspect that every sally out of harbour might be preliminary to the action which they had been living in increasing dread of every day and night for the preceding two years and a half, which finally made it practically impossible for the Germans to get out into the Bight sufficient forces to protect even their mine-sweeping craft. As a consequence, it is by no means unlikely that the continuation of the war for another few months might well have found the German navy, U-boats and all, effectually immobilized in harbour behind ever-widening barriers of mines.
