Well-Laid Plans: In the days leading up to the battle, Bragg tried to move his army between Rosecrans and Chattanooga, hoping to force the Federals to the southwest, where they could be attacked and destroyed. On September 18, the Rebels worked to push across West Chickamauga Creek at several points, resulting in sporadic fighting. The main battle broke out the following day. (Map Graphics © DFL Group 2018)
