The third and final day of the battle is most often seen as only Pickett’s Charge but there were other aspects of that day’s fighting. A feint at taking Culp’s Hill to occupy troops and possibly force the Union to reinforce did not work. Likewise a weak effort on the left flank accomplished nothing. The more significant challenge was a large unit of cavalry coming to attack behind the center of the Union line but it was defeated five miles from its destination. So the last effort was a charge by nearly 15,000 men across one mile of open ground. It failed and the invasion of the North ended as Lee and the army escaped in the night and eventually crossed the Potomac again into Virginia.
