"You must have been dreaming, stupid," said his lieutenant, irritable at being wakened. "There was no aeroplane here at nightfall; one couldn’t have gone up if it hadn’t come down first, and I must have heard that. Think yourself lucky I don’t report you for sleeping on duty. Feldwebel, bring the men back." The lieutenant turned on his heel and plodded grumbling back down the hill. The glare of Verey lights, the bursting of shells in the sky westward, might have confirmed the man’s story; but Lieutenant Schnauzzahn was never the man to admit himself in the wrong. IV A little before eleven on the following night, the Germans on that part of the front were thrown into agitation by a sudden burst of unusually violent gun-fire from the British artillery. Such a bombardment was commonly preliminary to an infantry attack, and the German soldier, though brave enough, is no longer quite easy in mind at the prospect of meeting British "Tommies." The few men in the front trenches cowered on the ground or in their dug-outs; the communication and support trenches filled up; and Verey lights illuminated the No Man’s Land across which they expected the enemy to swarm when the bombardment ceased. The deafening din and crash stopped as suddenly as it had begun. The Germans rushed into their front trenches. But there was no sign of movement on the now brightly lit space. There was no rifle fire, no bombs, no sound of cheering. All was quiet. They were puzzled. Was the attack postponed? The shelling had not lasted long enough to do very much damage. Perhaps it was intended to frighten them. None would admit that, if such were the object, it had succeeded. For a time they stood to arms, watchful, suspicious, uneasy. But the bombardment was not resumed. Nothing showed above the British parapets. They loosed off a few shots to relieve their feelings; then settled down to the weary night-work of the trenches. At the moment when this brief bombardment opened, Burton made his ascent from the aerodrome behind the British lines. At the moment when it ceased he was circling behind the German lines, some 2000 feet in the air, vainly endeavouring to pick up the pre-arranged signal-lights in the hollow. His flight had been carefully timed with the bombardment; he ought to have landed under cover of the noise; but the best arrangements are apt to be nullified by the unforeseen. A mist blanketed the ground, dense enough to obscure completely any lights of less than electric intensity.
