During the campaigns of 1863 in Tennessee, Cleburne and his soldiers fought at the Battle of Chickamauga. They successfully resisted a much larger Union force under Maj. Gen. William T. Sherman on the northern end of Missionary Ridge during the Battle of Missionary Ridge, and Joseph Hooker at the Battle of Ringgold Gap in northern Georgia, in which Cleburne's men again protected the Army of Tennessee as it retreated to Tunnel Hill, Georgia. Cleburne and his troops received an official Thanks from the Confederate Congress for their actions during this campaign.
