For more than eighteen months the Grand Fleet had been at war. It was the centre of the great web of blockading patrols, mine-sweeping flotillas, submarine hunters, and troop-transport convoys, and yet as a Fleet it had never seen the enemy nor fired a shot except in practice. The fast battle cruisers, stationed nearest to the enemy in the Firth of Forth had grabbed all the sport that was going in the Bight of Heligoland, or in the Dogger Bank action. But though several of the vessels belonging to the Grand Fleet had picked up some share in the fighting—at the Falkland Islands and in the Dardanelles—Jellicoe with his splendid squadrons still waited patiently for the Day. The perils from submarines had been mastered, and those from mines, cast into the seas by a reckless enemy, had been made of little account by continuous sweeping. The early eagerness of officers and men had given place to a sedate patience. At short intervals the vast Fleet would issue forth and, attended by its screen of destroyers and light cruisers, would make a stately parade of the North Sea. All were prepared for battle when it came, but as the weeks passed into months and the months into years, the parades became practice “stunts,” stripped of all expectation of encountering the enemy and devoid of the smallest excitement. The Navy knows little of excitement or of thrills—it has too much to think about and to do. At Action Stations in a great ship, not one man in ten ever sees anything but the job immediately before him. The enemy, if enemy there be in sight from the spotting tops, is hidden from nine-tenths of the officers and crew by steel walls. So, if even a battle be devoid of thrills—except those painfully vamped up upon paper after the event—a “stunt,” without expectation of battle, becomes the most placid of sea exercises. I will describe such a “stunt” as faithfully as may be, adding thereto a little imaginary incident which will, I hope, gratify the reader, even though he may be assured in advance that I invented it for his entertainment. * * * * * It was the beginning of the afternoon watch, and the vast harbour of Scapa Flow was very still and sunny and silent. The hands were sitting about smoking, or “caulking” after their dinner, and the noisome “both watches” call was still some fifteen minutes away. But though everything appeared to be perfectly normal and sedate, an observant Officer of the Watch, looking through the haze within which the Fleet flagship lay almost invisible against the dark hills, could see a little wisp of colour float to her yards and remain. Forthwith up to the yards of every vessel in harbour ran an exactly similar hoist, and as it was dipped on the flagship it disappeared from sight upon all. It was the signal to prepare for sea, and now mark exactly how such a signal—seemingly so momentous to a civilian—is received by the Navy at war.
