Suddenly the mist broke, rolled away from a sunlit landscape. They were at the summit of a slight elevation. About them was open country, dotted with trees and farms. In front the road dropped and then mounted. He looked over the heads of the artillery-men before him and saw a long column of infantrymen ascending the further hill. It was for that column that the brigade had waited. The recognition of the fact reawakened perception through a linked memory. He heard again the pealing thunder of the guns, to which for some minutes he had been oblivious. Instantly an intense, anxious curiosity took possession of him. Where were they fighting? In the fog his mind had formed a picture of lines of guns coughing out flame and noise at each other, desperately in conflict, just at the other side of the curtain drawn before his eyes. Now, the veil dropped, he looked at reality and only so much of the picture persisted as to puzzle him. Save for the column marching ahead there was no sign of life in that open countryside. Yet the air was full of sound. No longer was it a series of dull concussions. It was one vast, continuous, ringing roar, broken at intervals by the sound of violent fracture as a puff of wind came to his cheek. Excitedly, he strained his eyes at the distances, seeking some point where he could localise the conflict. There was nothing. Yes! Far ahead of him, beyond the hill which the infantry were climbing, a faint haze of smoke hung in the air. In that haze tiny puffs sprang into being and spread lazily. There, then! Encouraged, his gaze searched the landscape. Far to his left, over a little wood that closed the view, hung another such haze, and, as his eyes ranged over the country, he saw a line of smoke-puffs leap from nowhere above a hill to his right. The line was constantly renewed until the smoke trailed across the blue sky like a cloud. A thrill ran through him. He forgot himself, lost all memory of his doubts. He quivered, but it was with eagerness to rush into the fight. Oh, to mount that hill and see what was happening! The infantry drew up over it, disappeared beyond the summit like a snake drawing in its tail. The artillery crawled onward.
