There were approximately 124,000 troops engaged at Chickamauga. Of this number, there were 58,000 Union soldiers and 66,000 Confederates. During the two-day battle, there were 34,000 casualties. Of these casualties, there were 16,000 Union; 18,000 Confederates. The Union army had lost the battle of Chickamauga. Still they had reached their objective—Chattanooga. Bragg’s plan was to attack the Union troops in Chattanooga on the morning of the 22nd. However, this failed to materialize. After some light skirmishing it was decided to call off this attack due to the Union troops being too strongly entrenched. The Union army was still holding their line up Lookout Mountain. Soon this line was abandoned since they realized that Bragg would only have to place forces at any point below in order to have control of the river line of supplies. REORGANIZATION OF THE ARMIES Both Rosecrans and Bragg immediately started a reorganization of their armies. The Confederate army was divided into three corps, the commands being given to Longstreet, Hardee and Breckinridge. These three corps had a total of 10 divisions. Wheeler was in command of the cavalry. On the Union side, McCook and Crittenden were removed from their commands of the 20th and 21st Army Corps. These two corps were consolidated into the 4th and Granger was given the command. The Reserve Corps which was formerly commanded by Granger was consolidated into the 14th Army Corps, Maj.-Gen. John M. Palmer, commanding. The Union army at this time had six divisions, commanded by Baird, Cruft, Davis, Johnson, Sheridan and Wood. The Artillery Reserve was commanded by Brannan. This latter force consisted of two divisions, each with two brigades. Col. Parkhurst commanded the Post of Chattanooga.
