Next I followed a practice learned from the best officer I ever had. He was Charley Edwards, a major of middling age, perhaps a little too far along to be a combat officer but he was a good one. He had a large family, a pretty wife and four children in steps, and his heart could ache with love and longing for them if he allowed it to. He told me about it. In his deadly business he could not afford to have his attention warped and split by love, and so he had arrived at a method. In the morning, that is if her were not jerked from sleep by an alert, he opened his mind and heart to his family. He went over each one in turn, how they looked, what they were like; he caressed them and reassured them of his love. It was as though he picked precious things one by one from a cabinet, looked at each, felt it kissed it, and put it back; and last he gave them a small good-by and shut the door of the cabinet. The whole thing took half an hour if he could get it and then he didn't have to think of them again all day. He could devote his full capacity, untwisted by conflicting thought and feeling, to the job he had to do—the killing of men. He was the best officer I ever knew. I asked his permission to use his method and he gave it to me. When he was killed, all I could think was that his had been and good and effective life. He had taken his pleasure, savored his love, and paid his debts, and how many people even approached that?
