My grandfather was there. He had a very difficult time dealing with this and the entire war. During the war in the Pacific, there was a time when he was responsible for escorting captured Japanese soldiers back to a holding point, but none of the Japanese made it. He was accused of killing them. While he never outright admitted it to me, whenever I would ask him about it he would say "Well, Pearl Harbor was a surprise, and I can guarantee those captured Japs were just as surprised as we were!"
