On Nov. 24, 1863, at the opening of the engagement, Pettus' Brigade of Stevenson's Division in Breckinridge's Corps was on the top of the mountain. At half after 12 o'clock noon, Brig. Gen. Edmund W. Pettus was ordered with three regiments, the 20th, 31st, and 46th Alabama, to proceed to the Cravens house. Arriving at this point, he found Walthall's Brigade holding a line from there to the palisades. Pettus immediately filed his line to the left in rear of Walthall's, moved forward, relieved it, and held the position. He also extended his line 150 yards below the road to connect with the left of Moore's Brigade. Later, after replenishing ammunition, Walthall returned to Pettus' line and fought with it until the close of the battle at night. At 8 P.M., Holtzolaw's Brigade of Clayton's Brigade in Stewart's Division relieved Walthall's Brigade and the 20th and 31st Alabama. At 2 A.M., the 46th Alabama withdrew from the mountain with Moore's and Holtzclaw's Brigades, which covered the Confederate retreat. The brigade's casualties were 9 killed, 38 wounded, and 9 missing.
