Major General James B. McPherson, the commander of the Union's Army of the Tennessee, had graduated at the head of his West Point class and was a friend of General John Bell Hood, then commanding the Confederate defense of Atlanta.  During the Battle of Atlanta, McPherson was riding to deploy his troops against a Confederate counter-attack when he encountered a group of Confederate skirmishers and was shot.  He was the second highest ranking Union officers to die in battle during the war.  He was thirty-five years old.
