Determination and efficiency are not unknown in His Majesty's Navy. But efficiency of a particular description was required, and this would necessitate special training, which, if practicable, must be continued until every officer and every man knew instinctively what to do and how to set about it, no matter what circumstances might arise, and until every piece of machinery and every device, however intricate, had been proved to be satisfactory for the purpose in hand. What then were the chances of success? Who could say? Clearly enough, there must have been a divergence of opinion on this point. Difficulties loom large. Optimism, on the other hand, is a very pleasant {63} encouragement. I believe, however, that even the most optimistic individual concerned in the enterprise was not entirely free from qualms as the event drew nearer. Complete success seemed at times to be so much to hope for. But Sir David Beatty and Sir Roger Keyes wouldn't hear of failure, and that alone did much to ensure success. They did not set themselves up on pedestals as men who _could not fail--they left no stone unturned to ensure success_. It would be difficult to imagine anything more calculated to bring about failure than any sign of doubt, or hesitation, on the part of the leaders of an enterprise. There _must_ be no failure--that was the long and short of it--it was the spirit which governed the actions of the great leaders of the past. But sentiment alone is insufficient to guarantee success. It is but a foundation stone on which to commence the building. Rotten timber erected on the firmest foundation will not provide adequate protection against the lightest gale. Nobody realised this more fully than Vice-Admiral Keyes, who was determined that every link of the chain should be of maximum strength commensurate with elasticity and general handiness. Many were the hours given to the consideration of the smallest details; without such work an operation becomes a mere gamble. {64} CHAPTER V PLANNING THE OPERATION. MATTERS AFFECTING THE PLAN. ATTACKS ON THE MOLE. A war operation, such as this, passes through various stages before it can be put into execution. It emanates originally from a suggestion. If the suggestion seems to bear further consideration certain individuals are ordered to appreciate the situation, that is, to thoroughly thrash out all the arguments for and against and to weigh the chances and effects of success and failure. Should the results of such an appreciation be favourable, the investigation leads to the formation of a Plan. [Sidenote: Formation of a Plan]
