Some two years later I caused the question to be reconsidered after taking up the appointment of First Sea Lord at the Admiralty (it had been under consideration between 1914 and 1917). More than one plan was discussed between Admiral Bacon (commanding the Dover patrol) and myself; one idea, which I favoured, was to utilise ships of the “Apollo” class, cutting down their upper works to render them less visible during approach. Meanwhile, other schemes for driving the enemy from the Belgian coast were in operation, so the question of blocking was deferred. In September, 1917, when it became clear that the object in view would not be effected by military operations during that year, I gave directions to the Plans Division of the Naval Staff, of which Rear-Admiral Roger Keyes had recently become the head, that plans for blocking Zeebrugge were to be prepared; later, after considering an independent proposal by Sir Reginald Bacon for attacking the mole by landing parties from monitors run alongside it, I decided that the operation was to be combined with the landing on the Zeebrugge mole. The main objective for the landing was the destruction of enemy destroyers known to be lying alongside the mole, and I considered that this landing would also be very useful in creating a diversion to facilitate the approach of the block ships. The scheme was eventually approved by me in November, 1917, and the training of the storming party and selection of the block ships were taken in hand. CHAPTER VI INCIDENTS AT SEA--NOVEMBER 1 TO DECEMBER 31, 1914 On November 1st I left Lough Swilly to confer at the Admiralty with the First Lord and the First Sea Lord, Lord Fisher, who had relieved the Marquis of Milford Haven in this post. During this conference, held on November 2nd, the requirements of trawlers, drifters, etc., for the patrol of the vicinity of the various fleet bases, the Minches, and the waters surrounding the Orkneys and Shetlands were discussed at length and decisions reached. The defence of the bases was also considered. I stated that the requirements of patrol vessels for the Orkney and Shetland areas were a total of 72, and for the Minches of 36.
