Frustrated with his prospects in Kentucky and low on supplies, Bragg withdrew fully from Kentucky through the Cumberland Gap, passed through Knoxville and Chattanooga, turned northwest, and eventually stopped in Murfreesboro, Tennessee. His army, joined with Smith's Army of Kentucky and together renamed the Army of Tennessee as of November 20, took up a defensive position northwest of the city along the West Fork of the Stones River. During a visit by Confederate President Jefferson Davis on December 16, Bragg was ordered to send the infantry division of Maj. Gen. Carter L. Stevenson to Mississippi to assist in the defense of Vicksburg. The loss of Stevenson's 7,500 men would be sorely felt in the coming battle. Bragg reorganized his army, and Kirby Smith left for East Tennessee.
