The battles around Chattanooga must be considered as ending in one of the most complete victories of the war. Bragg’s army was defeated, men and material captured, and the Confederates driven south. The mountainous defense line which the Confederacy hoped to hold had been pierced and large sections of it were in Union control. Chattanooga, the railroad center, was now in Union hands and the interior line of communication from this section of the Confederacy to Richmond, by way of Knoxville, was destined to remain in Union control for the remainder of the war. Not only Chattanooga, but Knoxville and the rich, food-producing East Tennessee section was lost to the Confederacy. With this came relief for the Union sympathizers in East Tennessee. Virtually all of Tennessee was now under Northern control.

The fortunes of war brought changes to both commanders. Bragg asked to be relieved from his command and went to Richmond to become military advisor to Jefferson Davis. President Lincoln promoted Grant, in March 1864, to command of all Union armies in the field. Grant then left Chattanooga for the East, to lead the attack against General Lee in Virginia.
