"The sun beat upon our heads and we lay there wondering what was going on in our particular sector, what was the significance of the intermittent firing, whether we were advancing or holding our own. For to the average soldier battle always remains a chaos and an impression of immense confusion; he has only a worm's-eye view of the affair; he has no way of knowing what it's all about. One minute he is advancing under fire; the next he is lying low; the next withdrawing. He receives definite orders and they are immediately countermanded; he rarely sees the enemy and the fire that is directed at him assumes astonishing impersonality, as though it were independent of any human agency."
