After the battle, Lee retreated west and southwest through Hagerstown, Maryland and into Virginia. Imboden's wagon train, composing of wagons and ambulances, stretched for over 17 miles. Meade considered pursuit, but determined that the defensive nature of the Appalachian passes prohibited full pursuit. Meade did harass Lee's retreat - which resulted in minor skirmishes and capture of various Confederate units, but full pursuit did not materialize. Meade's decision not to pursue Lee angered Lincoln, who expected a decisive victory. Also, the lack of vigorous pursuit showed Meade as being too cautious.
