 Because McClellan failed to pursue Lee aggressively after Antietam, Lincoln ordered that he be removed from command on November 5, 1862. Maj. Gen. Ambrose Burnside assumed command of the Army of the Potomac on November 9, 1862. McClellan wrote to his wife, "Those in whose judgment I rely tell me that I fought the battle splendidly and that it was a masterpiece of art. ... I feel I have done all that can be asked in twice saving the country. ... I feel some little pride in having, with a beaten & demoralized army, defeated Lee so utterly. ... Well, one of these days history will I trust do me justice."
