More than fifty-seven miles of wagon and ambulance trains and tens of thousands of livestock accompanied the army back to Virginia. The movement of supplies and troops over the challenging terrain of mountain passes and in the adverse conditions of driving rain and muddy quagmires is described in depth, as are General George G. Meade's attempts to attack the trains along the South Mountain range and at Hagerstown and Williamsport, Maryland. Lee's deliberate pace, skillful use of terrain, and constant positioning of the army behind defenses so as to invite attack caused Union forces to delay their own movements at critical times.
Brown concludes that even though the battle of Gettysburg was a defeat for the Army of Northern Virginia, Lee's successful retreat maintained the balance of power in the eastern theater and left his army with enough forage, stores, and fresh meat to ensure its continued existence as an effective force.
