He realised now that the wind high up had been blowing strongly due east. It had taken him a long way over the lines, and so he had not allowed himself enough time to get back before he had dived through the cloud-bank. Again he managed to escape in the chase, and left the pursuing aeroplanes far behind. Ahead of him he could see a line of curling smoke and vapour, with here and there little white puffs of smoke in the air. He was drawing near the lines, and evidently there was an action of some kind in progress. Soon he reached the belt of desolation, of broken houses, shell-torn trees, and devastated fields. Machine-guns on the ground began to fire at him. He could hear their staccato hammering, and could see the flaming streak of the bullets passing by him. Now he could hear, too, above the roar of the engines, the thud and crash of the shells and of the guns. Everywhere below were great spouts of smoke and earth leaping up as shell after shell burst on the ground. The air was full of the shrapnel barrage against the infantry. Once he had a sudden inspiration to pull back his control-stick. The machine shot up into the air, and he saw just beneath the smoke-burst of a shrapnel shell. If he had continued on a straight course he would have been hit by it, and probably brought down. Below him he saw something extremely interesting. In the sunken roads and shattered fortifications near Douaumont were masses of grey-green soldiers. The Germans apparently were gathered for an attack. He noted where these men were, and flew on across the shell-torn area behind the French lines, and landed as soon as he could. The machine ran into a shell-hole and crashed. He crawled out of the wreckage and stumbled across the churned-up ground to the nearest headquarters and reported what he had seen. Immediately action was taken by the French, the counterattack was forestalled, and the whole course of the battle was changed. Soon afterwards the airman reached the aerodrome without his machine, and found he had been reported as missing. That such an extraordinary chain of adventures can come to a man unexpectedly shows vividly the uncertainty and the romance of flying. The night-bomber, as he leaves his aerodrome, never knows whether, when dawn comes, he will be in his bed at the camp, or in a Dutch guard-room, or hiding in a German wood. For several months I led an agreeable placid life at the seaplane station. At dawn or at dusk I flew over the sea on my long solitary flights. During the day I wandered round the station, learning about the machines and the engines, and spending many hours in the wireless hut, with the vulcanite receivers over my ears, hearing ship after ship sending its messages in a variety of notes--some high-pitched whines; some urgent, impetuous; some tremendously loud--great cruisers thundering their unquestionable commands; some faint and remote from lonely vessels far away on distant seas.
