Once from the starry sky came the drone of a seaplane moving up from its base that lay to the southward. Another followed, another and another, skirting the coast and flying well out to sea to avoid the searchlights and anti-aircraft guns of the shore batteries. They passed invisible, and the drone of their engines died away. “Our spottin’ machines,” said the sight-setter. “They’re going up to spot for the monitors at daylight.” He jerked his head astern to the north, and yawned. “I reckon I’d sooner ’ave this job than screenin’ monitors wot’s bombardin’ Ostend. I don’t fancy them 15-inch German shell droppin’ round out o’ nuffink, an’ no chance of ’ittin’ back.” “They knocks seven-bells outer Ostend, them monitors,” said another. “_We_ ain’t knockin’ ’ell out o’ nobody, steamin’ up an’ down like one of them women slops in the ’Orseferry Road.” The speaker blinked towards the east where the stars were paling. “We’re all doin’ our bit,” said the gunlayer, “an’ one o’ these nights....” He shook his head darkly. The dawn crept into the sky: the faces beneath the duffle hoods grew discernible to each other, unshaven, pink-lidded, pinched with cold. Objects, shining with frozen dew, took form out of the black void. The outline of the bridge above them, and the mast behind, stood out against the sky; the head and shoulders of the captain, with his glasses to his eyes, appeared above the bridge screen, where he had been all night, watchful and invisible. The smoke trailing astern blotted out the rest of the flotilla following in each other’s wake. Aft along the deck, guns’ and torpedo-tubes’ crews began to move and stamp their feet for warmth. Away to starboard a circular object nearly awash loomed up and dropped astern. Another appeared a few minutes later, and was succeeded by a third. Mile after mile these dark shapes slid past, stretching away to the horizon. They were the buoys of the Channel barrage, supporting the mined nets which are but a continuation of four hundred miles of barbed wire.
