That IS pretty sad. I just read a new biography of Jackson and he clearly was NOT fighting to preserve slavery nor was he a traitor. He also wasn't killed by the bullet that hit him. As he was being carried off the field on a stretcher, he was dropped and apparently injured his ribs and possibly his lungs too. This only became apparent later when he was convalescing and developed pneumonia and possibly blood clots in his lungs. If that was the case, he could not have survived the injury despite what happened to his left arm.
