If the Officer of the Watch upon a ship knows his signals he will put his glass back under his arm and think, “Good, I’ve got off two days’ harbour watch keeping at least; my first and middle, too.” The signal hands on the bridge look at the calm sea, which will for once not drench them and skin their hands on the halliards, and gratefully regard the windless sky under which hoists will slide obediently up the mast and not tug savagely like a pair of dray horses. The signal bos’n turns purple with fierce resentment which he does not really feel, for he will be up all day and half the night beside the Officer of the Watch on the bridge running the manœuvring signals, and he loves to feel indispensable. There is no excitement on the mess decks, only a smile since sea means a period of peace of mind when parades and polishings are suspended, and one keeps three watches or sleeps in a turret all night and half the day. Besides there is deep down in the minds of all the hope that, in spite of a hundred duds and wash-outs and disappointments, this trip may just possibly lead to that glorious scrap that all have been longing for, and have come to regard as about as imminent as the Day of Judgment. The gunnery staff look important and the “garage men”—armourers and electricians, commonly called L.T.O.s, in unspeakable overalls carrying spanners and circuit-testing lamps—float round the turrets looking for little faults and flies in the amber. The bad sailors shiver, though there is hope even for them in the silence and calmness of the sky. There is no obvious bustle of preparation, for the best of reasons: there is nothing to do except to close sea doors and batten down; the Fleet is Already Prepared. Let the reader please brush from his mind any idea of excitement, any idea of unusualness, any idea of bustle; none of these things exist when the Grand Fleet puts to sea. The signal which ran up to the yards of the flagship and was repeated by all the vessels in the Fleet read: “Prepare to leave harbour,” and simply meant that the Fleet was going out, probably that night, and that no officer could leave his ship to go and dine with his friends in some other ship’s wardroom. By and by up goes another little hoist, also universally acknowledged; this makes the stokers and the engine room artificers, and the purple-ringed, harassed-looking engineer officers jump lively down below so as to cut the time notice for full steam down by half and be ready to advance the required speed by three knots or so. The sun dips and evening comes on; a glorious evening such as one only gets fairly far north in the spring, and a signal comes again, this time: “Raise steam for —— knots and report.” Now one sees smoke pouring forth continuously from the coal-driven ships, and every now and then a great gust of cold oil vapour from the aristocratic new battleships whose fires are fed with oil only.
