Towards the distant coast-line, with its steady flickers of lights at Ostend and Blankenberghe, we move, forgetting already the place on which we have just dropped our bombs. The turmoil of Bruges has subsided--only two wary searchlights stand sentinel at either side of the town, alert and scarcely moving. Those two are enough to give us warning, however, and we sweep to the left to leave the simmering inferno well to our starboard. Below lies the pallid moonlit country,--field and forest, chateau and canal,--clearly etched in a soft black pattern of shadows and dim light. Far, far to the south Ypres flashes and flares on the horizon, with its night-long artillery fire. Now that our job is done, we are not so fearful of being over enemy country, partly because we are used to it by now, and partly because we are leaving the interior farther and farther behind us, minute by minute, as the coast-line draws nearer. Unexpectedly I notice below the machine a curious white patch on the face of the country. Then I see others behind it, and realise that the coast-line is becoming swiftly blotted out under a layer of clouds. "Jimmy! Look--clouds! We'll have to go carefully," I remark, and have a look at the compass. "Let's turn a bit more south-east, and we are bound to see Ostend." We turn swiftly, and in a few minutes are above a white carpet of cloud, through which, to my joy, I can see very hazily the flashing light of Blankenberghe to my right. Over towards Zeebrugge rise a few parting strings of green balls as the last British machine turns out to sea. For ten minutes we fly on by compass, which I check by the coldly glittering North Star, that shines faithfully for us high in the deep blue of the sky. Then I see, running to and fro, and round and round, on the carpet of the clouds, little circles of light. Now and then one comes to a rift on the bank, and for a moment a beam of light shoots up into the sky, only to vanish again. The Ostend searchlights are vainly looking for us; our engines have been heard. Now we are approaching a new formation of clouds, lovely towering masses of cumulus, pearl-white in the light of the moon. Over an unreal world of battlement and turret, of mountain summit and gloomy valley, we move in a splendid loneliness beneath the scattered stars. This billowy world of soft and silvery mountain ranges is made the more strange by the restless discs of radiance which run and swoop and circle and dance in a mad maze of movement across the curving pinnacles and ravines. Now and again a searchlight, striking into the heart of some towering summit of cloud, illuminates it with a glorious radiance, so that it seems for a moment to be woven of the fabric of light.
