Sherman had about 16,600 men in the three divisions of Brig. Gens. Morgan Lewis Smith, John E. Smith, and his foster brother and brother-in-law Hugh Boyle Ewing, and three regiments of Col. Adolphus Buschbeck's brigade from the XI Corps. Sherman also had Jefferson C. Davis's division guarding his rear. Around ten o'clock that morning, Grant dispatched the rest of Howard's XI corps from Thomas to Sherman. Hardee had about 9,000 Confederates in the divisions of Cleburne and Walker with another 4,000 soon to arrive in Stevenson's division. On Hardee's left, Benjamin F. Cheatham's decimated division occupied the ridge between Thomas' and Sherman's fronts. However, at dawn, when Sherman was supposed to attack, he was opposed by just three small brigades under Cleburne—about 4,000 men—and only the Texas brigade of Brig. Gen. James A. Smith was actually positioned on Tunnel Hill. But seemingly unnerved by his incorrect positioning, Sherman delayed until about 9:00 o'clock. He selected just two brigades from Ewing's division to attack. Brig. Gen. John M. Corse would approach from the north, Col. John M. Loomis from the northwest, across the open fields between the railroads.
