“At first he thought the war could be fought and concluded swiftly in a traditional way. Then he watched the machine gunners pouring bullets into the lines of advancing German infantry as though there was no longer any value accorded to a mere human life. He saw half his platoon die under the shells of the enemy’s opening bombardment. He grew used to the sight and smell of torn human flesh. He watched the men harden to the mechanical slaughter. There seemed to him a great breach of nature which no one had the power to stop.”
