We had been resting there only a few minutes when we were opened fire on by some Johnnies from behind the wall in front of us. They were evidently a company of sharpshooters, who in their retreat had turned back, determined to look for an opportunity to get a crack at us. They had evidently come up that road until they reached the turn, there they formed themselves along behind the wall at the lower edge of the field, and opened fire. General Reno, his staff, and two or three other officers were sitting on their horses just to the rear of the brigade, which was massed there by regiment. General Reno was hit at that time and in that way, and died about eleven o'clock that night. There were not more than thirty or forty shots fired. A regiment back to the rear in a place where it could be handled better than we could in our massed state, moved around on to the Johnnies' right flank and opened fire on them, killing and wounding a number, and the rest retreated. About nine o'clock the morning of September 15th, we started down the west side of the mountain range, heading in the direction of Sharpsburg. As we clambered along down the hill, an incident occurred that amused us quite a little, we were meeting little bunches of prisoners that were being taken to the rear from time to time, they were in the main, stragglers that had been picked up by our cavalry. Glancing down a little side road we saw a squad of Johnnies approaching us, they were being followed by a mounted officer wearing the blue. We were soon able to see it was one of General Ferrero's staff. This officer, we learned later, was an inveterate forager and as the general and his staff passed along down the hill a little while before us, the officer saw some distance from the main road a rather prosperous looking bunch of farm buildings, and thinking there was a good opportunity to do some foraging, rode over there. The piazza was on the back side of the house and as he rode around the house, there sat seven Johnnies on the piazza, their guns were all standing in one corner a little distance from them. He was tremendously startled as well as they, but he got his senses first, got his revolver out and got the drop on them before one of them moved. He then ordered them into line and marched them over to the main road, arriving there as our regiment was passing along. As we wended our way down the side of the mountain, the view we had below of the valley of the Antietam was of surpassing beauty; Sharpsburg across the valley was barely distinguishable; then to the right and to the left, up and down the valley as far as the eye could penetrate, stretched one of the most beautiful valleys I have ever seen. The next day we lay in camp a mile or two from the Antietam River all day. The morning of the 17th, the battle opened on the right in good earnest, but not until well into the forenoon did it begin in our front, we being on the extreme left. Then we
