Gotcha- but in the case of a victory, Lee still must withdraw……with a bad limp after Gettysburg. The South could ill afford such victories.Lee's Pennsylvania incursion was prompted by a number of factors (among them seek needed food and forage, forestall Union offensives in Virginia, damage northern morale, relieve pressure at Vicksburg). Many of these wants were being achieved by Lee and his army and a clear battlefield victory over the AotP would have served as the icing on the cake, by demonstrating the strength of southern arms and the durability of an independent Confederacy. That would have made the incursion a real strategic success for the cause of the Confederacy had the ANV withdrew in triumph to Virginia, rather than in anguish and disgust.
But it certainly could have wrecked Lincoln's re-election bid in '64. I guess the political ramifications may have warranted Lee's bold move.
Talking out of both sides of my mouth now- better hush!
