But he was really horribly tired, and in the midst of the tension the blaze of lights in his head went out, and he fell into a half-conscious doze. When he started into full consciousness again the men were stirring, and he became aware that the sergeant was calling for volunteers. Volunteers for what? He didn't know and was afraid to ask. But it became clear to him that the one chance to wash his guilt away (was that funny old-fashioned phrase a quotation, and where did it come from?) was to offer himself for the job, whatever it might be. The decision once taken, he became instantly calm, happy and alert. He observed the gesture made by the other volunteers and imitated it. It was too dark for the sergeant to distinguish one man from another, and without comment he let Troy fall into the line of men who were creeping up out of the hollow. The awful cannonade had ceased, and as they crawled along single file between the trees the before-dawn twitter of birds rained down on them like dew, and the woods smelt like the woods at home. They came to the end of the trees, and guessed that the dark wavering wall ahead was the edge of a wheat-field. Some one whispered that the Marne was just beyond the wheat-field, and that the red flares they saw must be over Château-Thierry. The momentary stillness laid a reassuring touch on Troy's nerves, and he slipped along adroitly at the tail of the line, alert but cool. Far off the red flares still flecked the darkness, but they did not frighten him. He said to himself: "People are always afraid in their first battle. I'm not the least afraid, so I suppose this is not a battle" ... and at the same moment there was a small shrieking explosion followed by a horrible rattle of projectiles that seemed to spring up out of the wheat at their feet. The men dropped on their bellies and crawled away from it, and Troy crawled after, sweating with fear. He had not looked back, but he knew that some of the men must be lying where they had dropped, and suddenly it occurred to him that it was his business to go and see.... Was it, though? Or would that be disobeying orders again? The Ambulance driver's instinct awoke in him, and he did not stop to consider, but turned and crawled back, straight back to the place that the horrible explosion had come from. The firing had stopped, but in the thin darkness he saw a body lying in front of him in the flattened wheat. He looked in the direction from which he had come, and saw that the sergeant and the rest of the men were disappearing to the right; then he ramped forward again, forward and forward, till he touched the arm of the motionless man and whispered: "Hi, kid, it's me...."
