Harry grew pale, and nervous, and hunted to look at; and he had a touch of dysentery. But the worst of the poison was in his mind and heart. For a long time, as I have said, since he felt the beginning of those old doubts, and saw himself starting downhill, he had striven anxiously to keep his name high in men's opinion; for all liked him and believed in him. He had been ready for anything, and done his work with a conscientious pride. But now this bitterness was on him, he seemed to have ceased to care what happened or what men thought of him. He had unreasonable fits of temper; he became distrustful and cynical. I thought then, sometimes, of the day when he had looked at Troy and wanted to be like Achilles. It was painful to me to hear him talking as Eustace used to talk, suspicious, intolerant, incredulous.... I thought how Harry had once hated that kind of talk, and it was most significant of the change that had come over the good companion I had known. Yet sometimes, when the sun shone, and once when we rode back into Albert and dined quietly alone, that mask of bitterness fell away; there were flashes of the old cheerful Harry, and I had hopes. I hoped Philpott would be killed.... IV But he survived, for he was very careful. And though, as I have said, he stuck it for a long time, he was by no means the gallant fire-eater you would have imagined from his treatment of defaulters. Once round the line just before dawn was enough for him in that sort of country. 'Things are quiet then, and you can see what's going on.' He liked it best when 'things were quiet.' So did all of us, and I don't blame him for that. But that winter there was a thick crop of S.I.W.'s. S.I.W. is the short title for a man who has been evacuated with self-inflicted wounds--shot himself in the foot, or held a finger over the muzzle of his rifle, or dropped a great boulder on his foot--done himself any reckless injury to escape from the misery of it all. It was always a marvel to me that any man who could find courage to do such things could not find courage to go on; I suppose they felt it would bring them the certainty of a little respite, and beyond that they did not care, for it was the uncertainty of their life that had broken them. You could not help being sorry for these men, even though you despised them. It made you sick to think that any man who had come voluntarily to fight for his country could be brought so low, that humanity could be so degraded exactly where it was being so ennobled.
