“In marching, in mobs, in football games, and in war, outlines become vague; real things become unreal and a fog creeps over the mind. Tension and excitement, weariness, movement--all merge in one great gray dream, so that when it is over, it is hard to remember how it was when you killed men or ordered them to be killed. Then other people who were not there tell you what it was like and you say vaguely, "yes, I guess that's how it was.”
