In the early part of October the brigade went over into Sequatchie Valley, to help pursue Wheeler, who was destroying our supply train. October 9th, 1863, Mitchell's brigade was put into Brigadier General Jeff C. Davis' division, and was called 2nd brigade, 2nd division, 14th army corps, where we served until the close of the war. Our corps badge was an acorn--red one for first, white for second and blue for third division. About 2 a.m., October 27th, we in company with the rest of the brigade, crossed the Tennessee river below Lookout Mountain, on a pontoon bridge, to the assistance of the Potomac troops, who were coming to the support of the Army of the Cumberland, and the enemy were trying to prevent their advance by assaulting Gen Gray's division. The darkness was akin to blackness, and the volleys of musketry, together with the roar of cannon, rendered the night one long to be remembered. This battle in the night is known as the battle of Wauhatchie. On the afternoon of November 24, 1863, our attention was attracted to Lookout Mountain, which was ablaze with artillery and musketry. The battle of Lookout Mountain was on, and we had it in full view without participating in it, and as the blue advanced and the gray fell back, leaving their breast-works, camp, camp equipage, artillery, in fact everything that goes to equip an army, the scene being enacted filled us so full that we, too, indulged in a hearty, long and loud cheer, which was all we could do as the Tennessee river was between them and us. However, it was soon over and in a short time we received orders to break camp, which we did and left Stringer's Ridge the night of the 24th, crossed the Tennessee river north of Chattanooga and near the north end of Missionary Ridge, on a pontoon bridge, which we constructed after relieving the Rebel pickets. We went in line of battle, connecting with the 15th Corps and by the middle of the day the enemy had been dislodged from their stronghold (Missionary Ridge) and were in full retreat, with us annoying their rear guard. These two days, November 24th and 25th, were red letter days for the U. S. forces. Lookout Mountain and Missionary Ridge were ours, besides a large number of prisoners and many stand of arms, a large amount of artillery, and the enemy in full retreat.
