According to Maj. Thomas Kennedy Porter, Buckner's chief of artillery, the artillery of the corps was seldom used, the ground over which the battle was fought being so thickly wooded that the officers could not see more than 300 yards to the front, and could not ascertain what damage was inflicted. When Preston's division became hotly engaged and the enemy sent a large force to strengthen the line in his front, three batteries were then posted about 1,000 yards from the Chattanooga road, where the enemy was crossing, which did great execution, silenced the enemy's guns, cut off his reinforcements, and enabled Preston to capture between 500 and 600 prisoners.

In this day's battle, Forrest's cavalry was active and vigilant. Armstrong's division and Dibrell's brigade fought on foot and were always up with the infantry, for which General Forrest commended them with ‘pride and pleasure.’ Morton's and Freeman's Tennessee batteries rendered valiant service in resisting the advance of Gordon Granger's column. Forrest's men were without rations, his horses were without water and had only a partial ration for two days, but no complaint was made.

The army of Tennessee bivouacked within the enemy's intrenchments or upon the heights it had so gallantly won.

On the morning of the 20th of September, General Rosecrans reported present for duty, 67,877 officers and men. In his revised statement of casualties he reported a loss of 16, 170 killed, wounded and captured, of which 1,657 were killed on the field, 9,756 were wounded, and 4,757 were captured by the Confederates. He had 9,913 serviceable horses and 246 pieces of field artillery. Capt. Horace Porter, his chief of ordnance, reports the loss of 36 pieces of artillery, the same number of artillery carriages,
