Those words from Confederate Major John D. Barry led to one of the most famous cases of friendly fire in U.S. history. On the night of May 2, 1863, during the Battle of Chancellorsville, a cavalry force entered the Confederate camp in the darkness and Barry, taking them for Union soldiers, ordered his men to fire. It wasn’t the enemy, however, it was General Thomas “Stonewall” Jackson and his aids. Gen. Jackson was hit by three bullets, two in his left arm and one in his right hand.
Jackson’s left arm had to be amputated. When General Lee heard the news, he said, “He has lost his left arm but I my right.” Jackson developed pneumonia and died eight days later at the age of 39.
