From the second volume of David Powell's "The Chickamauga Campaign"
Another new arrival appeared a few weeks later. Major General Thomas Carmichael Hindman arrived in Chattanooga on August 13 (1863) from Richmond, bearing orders authorizing him to take command of Maj. Gen. Jones M. Withers division in Leonidas Polk's corps. Withers was a capable combat officer who had seen plenty of service - when healthy. Unfortunately, as the war continued he grew increasingly less so. He was absent for much of 1863, his division left in the hands of its senior brigadier, J. Patton Anderson, of Florida. Withers submitted his resignation that July, but agreed to stay on with the condition that he could assume a less active role. He was promptly transferred to district command in Mobile. Hindman, who was then on detached duty in Richmond, was sent as his replacement.
