The Confederate enthusiasm that had risen so high after Chickamauga had been dashed at Chattanooga. One of the Confederacy's two major armies was routed. The Union now held undisputed control of the state of Tennessee, including Chattanooga, the "Gateway to the Lower South." The city became the supply and logistics base for Sherman's 1864 Atlanta Campaign, as well as for the Army of the Cumberland, and Grant had won his final battle in the West prior to receiving command of all Union armies in March 1864.
