Sickles being where he was certainly threw a wrench in the Confederate game plan on Day 2. One of a number of things that went wrong for them that day.
I concur with the advice to take a guided tour first.
His command was destroyed, he lost his leg, and the gap he created in the Union line was only plugged by Hancock sacrificing the entire 1st Minnesota. Sickles didn't do anything to ruin the Confederates day
