How is Lee's exit from Gettysburg after the first day different from Longstreet?

Answer 1

Lee never exited Gettysburg (the battle anyway). He would not have been IN the middle of the town on the first day since there was a battle going on. He did send messages to his Corps commanders on the first day to take Culp's Hill and Cemetery Hill "if at all practicable."

As far as Longstreet was concerned, he was not available on the 1st day of battle, his Corps was strung out from Cashtown to Chambersburg. His divisions were not involved until the 2nd and 3rd days of battle. He was opposed to the attacks on both days and had advocated for flanking movements further south....but that's another discussion.

Answer 2

I don't know what you mean by exit. If you're referring to how Lee and Longstreet felt about the first day's fighting, I can help you with that. Lee felt that the Confederates had truly won a decisive victory and felt that they should push even farther in the battle. Longstreet was cautious however. He felt that the Confederates should remain on the defensive as they always did before the battle ever since the first days of the war. So Lee and Longstreet really had some differing opinions about the first day.
