Bragg considered various options, including an attempt to retake Corinth, Mississippi, or to advance against Buell's army through Middle Tennessee. He eventually heeded Kirby Smith's calls for reinforcement and decided to relocate his Army of Mississippi to join with him. He moved 30,000 infantrymen in a tortuous railroad journey from Tupelo, Mississippi, through Mobile and Montgomery to Chattanooga. Supply wagons, cavalry, and artillery moved overland under their own power through Rome, Georgia. Although Bragg was the senior general in the theater, Confederate President Jefferson Davis had established Kirby Smith's Department of East Tennessee as an independent command, reporting directly to Richmond. This decision caused Bragg difficulty during the campaign.
