Stonewall Jackson died on May 10 and was buried in Lexington, Virginia on May 15. The Civil War Battle of Chancellorsville, Virginia began on May 1, 1863. The next day, while reconnoitering with members of his staff, Jackson was accidentally fired upon by his own troops. The 18th North Carolina Infantry Regiment was responsible for the "friendly fire" incident. Jackson was struck by three .57 caliber bullets and was taken to a field hospital near the battlefield, where his left arm was amputated. On May 4th, Jackson was moved to a field hospital at the home of Thomas and Mary Chandler, near Guiney Station, approximately 30 miles from the battlefield.
