I saw much during my thirty years as a professional soldier, and I have watched the reactions of many men to pain, hunger and death, but all I have learned is that no two men react alike, and that no one man comes through the experience unchanged. I have never ceased to wonder at the thing we call human nature, with its times of beauty and its times of filthiness, or at the level of calm stupidity that lies in between the two. I have no theories and no remedies to offer.
