As the Confederates retreated into northern Georgia, Rosecrans pursued with three columns. He believed that the rebels were demoralized, and allowed his units to become separated in the mountainous terrain. The center Union column under George Thomas had rushed forward to seize mountain gaps, and Bragg ordered an attack on his men's position at Davis's Cross Roads in the front and flank. But expected reinforcements did not arrive to the units directed to make the attack, and their commanders agreed not to strike. Next morning more troops did arrive, but by that time the Union forces had been strengthened, and fell back skirmishing with the Confederates, having got word of the attack.
