On December 3, 1917, the plan had emanated from an Admiralty Department under the direction of Rear-Admiral Keyes, Director of Plans, to give him his titles at that time. The nature of the operation and the customary procedure, having regard to the locality concerned, would entail its execution coming under the command of the Vice-Admiral at Dover. The latter apparently desired to modify the plan and submitted his proposals on December 18th. He suggested the idea that an attack on the Mole, not previously mentioned in the plan, should accompany the blocking operations. As a diversion (pardon the anticipation) this idea was eventually embodied after {68} exhaustive consideration had shown it to be necessary. [Sidenote: Vice-Admiral Keyes] As already stated this particular type of diversion was somewhat similar to that included in a previous scheme, referred to on page 17 as having been forwarded in May, 1917, which at that time was considered impracticable by the Vice-Admiral at Dover. The actual method proposed on December 18th by the latter for giving effect to his idea of a Mole attack was not followed, for it happened that Rear-Admiral Keyes took over the Dover Command, with the acting rank of Vice-Admiral, after his own plan had been submitted, and nearly four months before it could be carried out. The coincidence--if it was a coincidence--was extremely advantageous. An operation can be so much better worked up by an officer who has handled the plan from its inception. But in the ordinary course of events such an arrangement is impracticable. An admiral or general in active employment in the face of the enemy, as a general rule, has not sufficient spare time for the formation of plans in every detail, nor has he a superabundance of staff officers for the purpose. No words of mine could ever do justice to Sir Roger Keyes, so I will not make the attempt. Suffice it to record that every soul in the enterprise possessed complete confidence in his leadership; this fact was half the battle won before we even started. Admiral Keyes was given an absolutely free hand by Their Lordships; all the details, from A to Z, were worked out under his direction. The "paper scheme" rapidly developed into practical shape; I will endeavour to describe the data and arguments from {69} which its final shape was evolved. Before doing so, however, it may be as well to put on record a fact that might escape the notice of the reader. The responsibility of the Officer in Command of an operation must necessarily be great, but the responsibility of the Higher Command, in this case the Board of Admiralty, which has to either sanction or disallow the execution of proposed operations, is by no means small. That they sanctioned it in this case and also chose the right man to carry it out must never be forgotten.
