Private O'Shea, sentry on No. 3, overlooking the flats whereon stood the stables, was straining his ears to catch the expected call of eleven o'clock from No. 2, and watching the distant trail of lights, and was able to say next morning that the Flyer was just shoving its nose behind Two-Mile Ridge as the second call, that of eleven o'clock, started round. The moon in its first quarter, though bright and clear, was then dipping low in the west and objects were by no means as distinct as they had been when he came on post soon after nine and saw Lieutenant Ray set forth, mounted, up the Minneconjou. O'Shea remembered that Hogan, who took care of the lieutenant's horse, had come back across his post, and they had had a brief talk about him, Hogan saying the lieutenant wasn't half satisfied with having blackened the eyes of a bigger man. "He was that savage and snappy he rowed me for keeping him so long waiting, when, dear knows, he couldn't have stood at the back gate ten minutes." O'Shea owned that he and Hogan, "all the fellers, for that matter," had wished their little bantam of a canteen officer could have had two minutes more at "the big feller." Foster had no friends among the enlisted men at the fort. It presently became a question whether or no he had not enemies. Hogan was just saying the lieutenant told him not to sit up for him when they became aware of someone approaching, heard the rattle of a sword, and saw the officer of the guard barely forty yards away, whereat Hogan skipped for the stables. Then came the next important point in O'Shea's statement. Just as the tail lights of the big train disappeared behind the ridge he heard the sudden single blast of the whistle sounding the old-time signal "down-brakes," noted the instant change from the loud, pulsing exhaust to the scream of escaping steam, heard even the squeal and grind of the tightly clamped wheels as the Flyer slowed down to a standstill. He was wondering what had happened when the third relief came round and Private Schmitz took his place on post, as subsequently he replaced O'Shea on the stand.
