Most of its members were from Waco, San Antonio, Bonham, Weatherford, and Austin. After serving with the Army of New Mexico it was assigned to Green's, Hardeman's, and Debray's Brigade in the Trans-Mississippi Department. The regiment fought in Louisiana and reported 99 casualties at Cox's Plantation and 7 at Bayou Bourbeau. Later it moved to Huntsville, Texas, and disbanded before the surrender in June, 1865. The field officers were Colonels Thomas Green and Henry C. McNeill, Lieutenant Colonel Denman W. Shannon, and Majors Samuel A. Lockridge and Hugh A. McPhaill.
