By 6:00 pm, the center of Bragg's line had broken completely and fled in panic, requiring the abandonment of Missionary Ridge and a headlong retreat eastward to South Chickamauga Creek. The sole exception to the panicked flight was Cleburne's command, his division augmented by two brigades from another division. As the only command not in complete disarray, it was the last unit to withdraw and formed the rear guard of Bragg's army as it retreated eastward. Only Sheridan tried to pursue beyond Missionary Ridge, but he finally gave up late that night when he clearly was being supported by neither Granger nor Thomas.
