It has already been mentioned that a considerable percentage of the vessels and craft engaged in the attack were commanded and manned by officers and men of the Royal Naval Reserve and Royal Naval Volunteer Reserve. The majority of the smoke-screening craft and rescue craft came under that heading. Without the smoke the operation must have failed. Without the rescue work the price paid for success would have been excessive. These representatives of the auxiliary naval services earned a full measure of admiration. Their daring in the face of danger, their coolness in situations which lacked nothing in excitement, their initiative when confronted with the unexpected, and their perfect co-operation with the remaining forces engaged in the enterprise, were worthy of the best traditions of the Navy. The more that one considers the dependence upon seamanship, the practical use of technical knowledge, the mental and physical strain, the value of perfect discipline, and the initiative called for on such an occasion, the greater is one's admiration for these fine fellows of whom the majority had seen comparatively little of sea life and had lacked that severity of training which is inseparable from the naval profession. The reports of all Commanding Officers contained one particular similarity--I refer to the behaviour of the men. The cynic who might be inclined to discount such unqualified praise, on the plea that the men were specially chosen, could easily be silenced. The specially selected personnel were certainly picked {264} with difficulty, not because the desired qualities were rare, but for exactly the opposite reason. The Grand Fleet and naval bases contained many thousands of such men; the embarrassment lay in deciding who of these thousands should be taken to make up the seventeen hundred and eighty personnel required. But the latter were only required for some ten vessels out of one hundred and sixty-two; required because those ten vessels were out of commission and therefore had no crews. The remaining one hundred and fifty-two vessels and craft took part in the operation with their ordinary crews, and I repeat that the behaviour of the crews of _all_ units was exemplary. But co-operation between units, and efficiency of individuals, are not alone sufficient to ensure success. Absolute confidence and perfect co-operation between officers and men, founded on true discipline, is of vital importance. Without these, little or nothing can be achieved in war. The seeds of these vital requirements were sown by our forefathers. Those of our predecessors who, although too old to serve in the Great War, were still in the land of the living had reason to feel proud at the success attained by their pupils. There is one other human aspect which cannot be omitted without leaving a serious blank in these pages. That aspect is the one of Leadership.
