n On September 18-20 1863 in Catoosa and Walker counties of Virginia, General Rosecrans was determined to drive the Confederates out of Chattanooga. Rosecrans’ three corps approached Chattanooga at different routes. After being defeated by General Rosecrans, General Bragg was set on retaking Chattanooga. So he set out on the 17th and fought with the Union cavalry.
n The Union had Spencer repeating rifles. The battle lasted through the 18th but the victory was once again the Union’s. The next morning, Rosecrans discovered a gap in his defense. In trying to close it, he made yet another one. The Confederate immediately exploited it. The heavy fighting lasted into the night but finally the Confederacy drove the Union out and took the town.
