One regiment was suffering from little less than a panic. Perpetually and day after day sentinels had been missing. Worse than this, they had been surprised, apparently, and carried off without giving any alarm or having time to utter a sound. It would happen that a sentinel went forward to his post with finger upon his trigger, while his comrades searched the woods around and found them empty. When the relief came, the man would just be missing. That was all. There was never a trace left to show the manner in which he had been conveyed away: only, now and then, a few drops of blood splashed on the leaves where he had been standing. The men grew more and more uneasy. Most suspected treachery. It was unreasonable, they argued, to believe that man after man could be surprised without having time even to fire his musket. Others talked of magic, and grew gloomy with strange suspicions of the Indian medicinemen. At any rate, here was a mystery. Time would clear it up, no doubt; but meanwhile the sentry despatched to his post felt like a man marked out for death. It was worse. Many men who would have marched with firm step to death in any familiar shape, would go with pale cheeks and bowed knees to this fate of which nothing was known except that nothing was left of the victim. Matters at length grew intolerable. One morning, the sentinels having been set as usual overnight, the guard went as soon as dawn began to break to relieve a post that extended far into the woods. The sentinel was gone! They searched about, found his footprints here and there on the trodden leaves, but no blood--no trace of struggle, no marks of surrounding enemies. It was the old story, however, and they had almost given up the problem by this time. They left another man at the post, and went their way back, wishing him better luck. "No need to be afraid," he called after them, "I will not desert." They looked back. He was standing with his musket ready to fly up to his shoulder at the slightest sound, his eyes searching the glades before him. There was nothing faint about Tom, they determined, and returned to the guard-house. The sentinels were replaced every four hours, and at the regular time the guard again marched to relieve the post. The man was gone! They rubbed their eyes, and searched again. But this one had disappeared as mysteriously as his fellows. Again there was no single trace. But it was all the more necessary that the post should not remain unguarded. They were forced to leave a third man and return, promising him that the colonel should be told of his danger as soon as they got back.
