Major-General Longstreet came up about 4 o’clock with the commands of Brig. Gens. N. G. Evans and D. R. Jones. I had now become familiar with the ground, and knew all the vital points, and, had these troops reported to me, the result might have been different. As it was, they took wrong positions, and, in their exhausted condition after a long march, they were broken and scattered. Our whole left was now fairly exposed, and the Yankees had but to push down to seize the turnpike. It was now dark, however, and they feared to advance. All the available troops were collected behind a stone wall, to resist an approach upon the turnpike from the left. Encouraged by their successes in that direction, the Yankees thought that it would be an easy matter to move directly up the turnpike; but they were soon undeceived. They were heroically met and bloodily repulsed by the Twenty-third and Twenty-eighth Georgia Regiments, of Colquitt’s brigade. The fight lasted for more than an hour after night, but gradually subsided as the Yankees retired. General Hood, who had gone in on the right with his two noble brigades, pushed forward his skirmishers and drove back the Yankees.
We retreated that night to Sharpsburg, having accomplished all that was required–the delay of the Yankee army until Harper’s Ferry could not be relieved.
