The war made York more deeply religious. The diary he kept passed from simple notations about "places he had been" to a record of his thoughts and feelings. In it are many quotations from the Bible; many texts of sermons he heard while on the battlefields of France. With the texts were brief notes that would recall the sermons to his memory. The book is really "a history" of his religious development. When he would kneel by a dying soldier he would record in his diary the talk he had with his comrade and would write the passages of Scripture that he or the dying man had spoken. It was upon this his interests centered. To others he left the task of telling of the battle's result. He wrote in his diary this simple story of his fight with the battalion of German machine guns: "On the 7th day of October we lay in some little holes on the roadside all day. That night we went out and stayed a little while and came back to our holes, the shells bursting all around us. I saw men just blown up by the big German shells which were bursting all around us. "So the order came for us to take Hill 223 and 240 the 8th. "So the morning of the 8th just before daylight, we started for the hill at Chatel Chehery. Before we got there it got light and the Germans sent over a heavy barrage and also gas and we put on our gas-masks and just pressed right on through those shells and got to the top of Hill 223 to where we were to start over at 6:10 A.M. "They were to give us a barrage. The time came and no barrage, and we had to go without one. So we started over the top at 6:10 A.M. and the Germans were putting their machine guns to working all over the hill in front of us and on our left and right. I was in support and I could see my pals getting picked off until it almost looked like there was none left. "So 17 of us boys went around on the left flank to see if we couldn't put those guns out of action. "So when we went around and fell in behind those guns we first saw two Germans with Red Cross band on their arms. "Some one of the boys shot at them and they ran back to our right. "So we all ran after them, and when we jumped across a little stream of water that was there, there was about 15 or 20 Germans jumped up and threw up their hands and said, 'Comrade.' The one in charge of us boys told us not to shoot, they were going to give up anyway. "By this time the Germans from on the hill was shooting at me. Well I was giving them the best I had. "The Germans had got their machine guns turned around. "They killed 6 and wounded 3. That just left 8 and then we got into it right. So we had a hard battle for a little while. "I got hold of a German major and he told me if I wouldn't kill any more of them he would make them quit firing. "So I told him all right. If he would do it now. "So he blew a little whistle and they quit shooting and came down and gave up. I had about 80 or 90 Germans there.
