After Chickamauga, Ector's brigade transferred to Mississippi where it joined the division of Samuel Gibbs French in Leonidas Polk's corps. The brigade participated in the Meridian campaign in early 1864. For the Atlanta Campaign, Ector's brigade included the 29th and 39th North Carolina Infantry, the 9th Texas Infantry, Jacques's Battalion, and the 10th, 14th, and 32nd Texas Cavalry. On 19 May 1864, French's division joined Joseph E. Johnston's army with 4,174 soldiers. In the Atlanta Campaign, the 32nd Texas Cavalry lost 11 killed and 35 wounded. The brigade fought at Cassville, New Hope Church, Latimer's Farm, Peachtree Creek, Atlanta, and Lovejoy's Station. At the Battle of Allatoona on 5 October 1864, the regiment was assigned to guard the artillery and missed this bloody action. However, Captain Somerville of the regiment led a raid on a Union warehouse in which he was wounded in the stomach and left for dead. Somerville was captured and nursed back to health by the Federal doctors, dying in 1917. Colonel Andrews succeeded to command of the brigade after Allatoona. Ector was wounded during the Atlanta campaign and lost his leg, though he later rejoined the army.
