Meade was severely criticized for allowing Lee to escape, just as Maj. Gen. George B. McClellan had done after the Battle of Antietam. Under pressure from Lincoln, he launched two campaigns in the fall of 1863—Bristoe and Mine Run—that attempted to defeat Lee. Both were failures. He also suffered humiliation at the hands of his political enemies in front of the Joint Congressional Committee on the Conduct of the War, questioning his actions at Gettysburg and his failure to defeat Lee during the retreat to the Potomac.
