On This Day in History May 2, 1863: Confederate General Thomas "Stonewall" Jackson (January 21, 1824 - May 10, 1863) was accidentally wounded by his own men at the Battle of Chancellorsville, Virginia.
The post Stonewall Jackson from the History Channel described what happened to Jackson after he was shot:
But the victory was not without cost. Jackson’s brutal attack ended at sunset, and he took some men into the forest to scout ahead. A North Carolina regiment mistook them for enemy cavalry and opened fire, severely wounding Jackson. He was taken from the field and General J. E. B. Stuart (1833-64) took over his command. Doctors determined that a bullet had shattered the bone just below his left shoulder, and they quickly amputated Jackson’s left arm. He was transferred to a field hospital at a nearby plantation to recover. Lee dispatched a letter, writing, “Could I have directed events, I would have chosen for the good of the country to be disabled in your stead.” Jackson initially appeared to be healing, but he died from pneumonia on May 10, 1863, at the age of 39.
