It was nearly five o'clock when the enemy had disappeared in the woods beyond Fox's Gap and Willcox could reform his shattered lines. As the easiest mode of getting Sturgis's fresh men into position, Willcox made room on his left for Ferrero's brigade supported by Nagle's, doubling also his lines at the extreme right. Rodman's division, the last of the corps, now began to reach the summit, and as the report came from the extreme left that the enemy was stretching beyond our flank, I sent Fairchild's brigade to assist our men there, whilst Rodman took Harland's to the support of Willcox. A staff officer now brought word that McClellan directed the whole line to advance. At the left this could only mean to clear our front decisively of the enemy there, for the slopes went steadily down to the Rohrersville road. At the centre and right, whilst we held Fox's Gap, the high and rocky summit at the Mountain House was still in the enemy's possession. The order came to me as senior officer upon the line, and the signal was given. On the left Longstreet's men were pushed down the mountain side beyond the Rohrersville and Sharpsburg roads, and the contest there was ended. The two hills between the latter road and the turnpike were still held by the enemy, and the further one could not be reached till the Mountain House should be in our hands. Sturgis and Willcox, supported by Rodman, again pushed forward, but whilst they made progress they were baffled by a stubborn and concentrated resistance. Reno had followed Rodman's division up the mountain, and came to me a little before sunset, anxious to know why the right could not get forward quite to the summit. I explained that the ground there was very rough and rocky, a fortress in itself and evidently very strongly held. He passed on to Sturgis, and it seemed to me he was hardly gone before he was brought back upon a stretcher, dead. He had gone to the skirmish line to examine for himself the situation, and had been shot down by the enemy posted among the rocks and trees. There was more or less firing on that part of the field till late in the evening, but when morning dawned the Confederates had abandoned the last foothold above Turner's Gap and retreated by way of Boonsboro to Sharpsburg. The casualties in the Ninth Corps had been 889, of which 356 were in the Kanawha division. Some 600 of the enemy were captured by my division and sent to the rear under guard.
