October 23, 1863.
General L. POLK,
You are relieved from duty with the Army of Tennessee and will relieve Lieutenant-General Hardee of the command of the troops he has been organizing in the Department of Mississippi. I leave to-night for Mobile. Will remain to-morrow and next day at that place, and then proceed by railroad to Montgomery. Would be glad to meet you at either place, as may be convenient to you.
