Duff's Texas Cavalry (33rd Cavalry) (Confederate)
33rd Cavalry Regiment was organized in April, 1863, by using the 14th (Duff's) Texas Cavalry Battalion as its nucleus. Its members were recruited at San Antonio, Port Lavaca, and Mt. Vernon, and in Kaufman County. This unit served in Gano's and Hardeman's Brigade, Trans-Mississippi Department, and was active along the lower Rio Grande. In April, 1864, it was near Bonham, Texas and contained 23 officers and 307 men. On June 2, 1865, it was included in the surrender. The field officers were Colonel James Duff, Lieutenant Colonel James R. Sweet, and Majors Santos Benavides and John T. Brackenridge. 
Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
