Ever wanted to know where Stonewall Jackson’s arm is buried? You can read about it here. In case you didn’t know, Stonewall Jackson was wounded at the battle of Chancellorsville in May 1863 by his own troops while scouting a mission in the dark. Anxious Confederate pickets thought he was a Yankee and opened fire on him and those riding with him.

It was a great loss. Jackson had just helped Robert E. Lee win one of his greatest victories against a northern army that outnumbered the Rebels 2:1. Yet, it was a dearly bought victory. Chancellorsville was one of Lee’s an Jackson’s bloodiest battles, costing them roughly 13,000 troops. And it was the loss of Jackson that perhaps, some have argued, doomed the Confederacy.

After his arm was amputated, Jackson came down with pneumonia, and it was that–not the wound–that killed him, a week after the battle.
