I could hear the noise of the cavalry camp on the lawn, and the tramp of feet in the hall.

Occasionally some voice sounded clear enough so I could distinguish the words.

I opened the door leading into the dining-room, but that apartment was deserted.

There was evidently nothing to do but wait, and I lay down on the couch between the windows, looking up at the green leaves shaking in the breeze.

Fatigued with the labors of the previous night, before I realized the possibility I was fast asleep.
I must have remained there some hours, totally unconscious, for when I finally awoke it was nearly dark, the dusk so pronounced I could scarcely see across the room.
