General Hardee, again in corps command, renewed this day his old association with Cleburne. The latter, assigned to position by Hardee, at once perceived that Sherman, having already gained a lodgment on a spur of Missionary Ridge, near the river, meant to get possession of the main ridge between Cleburne's right and the Chickamauga, cutting Polk off from Cleburne and endangering the safety of the whole army.
