Union General William Rosecrans was following up his successful capture of Chattanooga when Confederate General Braxton Bragg turned his retreating force and fought a three-day battle in north-western Georgia near Chickamauga Creek. Union troops were holding their own when an error from Rosecrans opened a gap in his lines. Bragg then advanced and placed Chattanooga under siege. Rosecrans was replaced within weeks as commander of the Army of the Cumberland. (By John Osborne)
