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.
