At the opening of the campaign, Maj. Gen. W. S. Rosecrans's Federal Army of the Cumberland was deployed southeast of Nashville, around Murfreesboro, while Gen. Braxton Bragg's Confederate Army of Tennessee was deployed to the south and east along a line from Shelbyville to Wartrace, with cavalry extended as far east as McMinnville and as far west as Columbia.

Sept. 19 First Day of the Battle of Chickamauga. Thomas, with much of XIV Corps, fails to eliminate the Confederate presence west of Chickamauga Creek. Confederate attacks score some notable successes in the Viniard Field, but are unable to exploit the gains. At the end of the day the Federal battle line roughly follows the LaFayette Road, with an outward bulge on the left flank at the Kelly Field.

Bragg orders a concerted effort to turn the Federal left flank the next morning.

Longstreet arrives at Bragg's headquarters from Virginia, after almost wandering into the Federal lines.

Sept. 20 Second Day of the Battle of Chickamauga. Polk's belated attacks on the Federal left fail to achieve a breakthrough in the morning. At about noon, Longstreet's column scores a major breakthrough in the Union right-center, sending most of two divisions and portions of several others, along with the Federal trains and Rosecrans himself, streaming back to Chattanooga. A remnant of the Federal right wing forms a ragged line on Snodgrass Hill and Horseshoe Ridge, and hold on until near nightfall to allow the army to retreat back to Chattanooga in a somewhat orderly fashion. At the end of the day, Bragg does not understand that he has won a major victory, and fails to pursue the Yankees closely.
