On May 10, 1864, he was promoted to the rank of brigadier general and served later that year in command of a brigade in the army of Nathaniel P. Banks in the Red River Campaign. He saw action in several battles in that campaign, including Sabine Crossroads, Pleasant Hill, and Monet's Ferry, where he led a major assault in which he suffered a severe leg wound that necessitated amputation. After convalescing, he was assigned to administrative duty for the rest of the war, commanding various garrisons and supply trains.
