Missionary Ridge, to which I was ordered, runs nearly north and south, parallel to the Tennessee River, which is about 1 1/2 miles west of it. From the tunnel north along the ridge it is about a mile to the Chickamauga River, which bounds the ridge on that side, flowing thence westwardly into the Tennessee River. To simplify the description, the two rivers and the ridge may be said to form three sides of a square. The Tennessee Valley, between the rivers and the ridge, is mostly level, with a continuation of cleared fields bordering the ridge, but immediately in front of the center of my position, about 1,200 yards north and 600 yards west of the railroad tunnel, was a high detached ridge, which in a military point of view dominated over every point within cannon range.
After passing through the tunnel the railroad runs in a north-easterly direction to the Chickamauga, which it crossed on the bridge Brigadier-General Polk was guarding. From the east side of the main ridge there projected two spurs, one, on the north boundary, with its precipitous north side washed by the Chickamauga; the other, jutting out just north of the tunnel, did not run directly back, but northeasterly for 1,000 yards, forming an acute angle with the parent ridge. Opposite the right of this spur, the main ridge was intersected by a little valley, through which came a road from the Tennessee Valley, where the enemy now was. The highest point on my line, and the point of chief interest in the battle on the right, and which I shall designate in this report as Tunnel Hill, was situated on the main ridge 250 yards north of the tunnel. The position pointed out for my command by Major Poole was to occupy, with one brigade, the detached ridge in the Tennessee Valley, and with the remainder of my command to stretch from the top of Tunnel Hill to the right of Walker's division, three-quarters of a mile south of the tunnel.
I sent Major Poole to inform General Hardee that I had but three brigades, and could not cover so long a line. The head of my division, Smith's (Texas) brigade was now at hand, and at the same moment reported to me from the detached ridge. Private Henry Smith, of the signal corps of my division, informed me he was just from that point; that the enemy was advancing on it in line of battle. I ordered Smith to move his brigade rapidly and try to get possession of it before the enemy had gained a foothold, but if he found the enemy in possession to fall back on the main ridge. General Smith moved into the valley, but was fired on from the top of the detached ridge as he approached its foot. Smith was too late. The enemy had crowned the ridge. He therefore marched by his right flank on to the main or Missionary Ridge, and formed on its top, his two left regiments facing the detached ridge, his right regiment thrown back in an easterly direction to protect his flanks. Smith had scarcely thrown out skirmishers before he was briskly attacked by the skirmishers of the enemy.
In the meantime, I had placed Lowrey's brigade in position south of the tunnel and was about placing Govan's brigade on his left so as to complete my connection with Walker's division, when my attention was attracted to the fighting on my right. It was evident the enemy was endeavoring to turn my right flank and get possession of the main ridge between my right and the Chickamauga. If he succeeded, my connection with Brigadier-General Polk and my line of retreat by the bridge he was guarding was cut, and the safety of the whole army was endangered. Instead of placing Govan's
