Reuben, Mike, and I were advancing as I have described, somewhat ahead of the train, when towards evening we entered a valley, the hills sloping away on either side of it.  At the further end we expected to find a stream, at the side of which we could encamp.  I was leading, Mike was next to me, and Reuben was nearest the train.  The ground I was traversing was somewhat rough, and I was leaping from one rock to another, when I fell and sprained my ankle.  Just as I got up--being then on higher ground than my companions, and having a more extensive view--I saw a large band of horsemen approaching at full gallop.  I knew at once that they were Redskins.
