After being wounded in the neck at Chickamauga, Hindman and his Legion continued to fight along with the Army of Tennessee against General William Tecumseh Sherman in the Atlanta Campaign, seeing action across northwestern Georgia from the First Battle of Dalton, to the Battle of Resaca; the Battle of New Hope Church; the Battle of Kolb's Farm; the Battle of Kennesaw Mountain, just outside Marietta, Georgia. On July 4, 1864, at Kennesaw Mountain, he was struck in the eye by a tree limb and fell off his horse. Hindman suffered severe injuries that left him unfit for service on the battlefield. He went to Atlanta and later Macon to recuperate from his injuries. Afterward, Hindman hoped that he would be able to fight after a full recovery. He applied for a transfer to the Trans-Mississippi Department. His request was denied by the Confederate War Department, but Confederate President Jefferson Davis offered Hindman a leave of absence until he had fully recovered from his "physical disability".
