I spent Saturday morning at the Historical Research Center at Hill College in Hillsboro, Texas and there is a wealth of wonderful information, books, microfiche, etc., available for anyone wishing to research Texas' participation in the War for Southern Independence. The archivist was exceedingly helpful and knowledgable about the Texas units. They have a copy of "The Lone Star Defenders, A Chronicle of the 3rd Texas Cav., Ross' Brigade," by Samuel Benton Barron, which has a good time line of battles, promotions, etc, - also came across a letter from Wilbur Thomas Meyers, Sons of Confederate Veterans, that identifies Jeff Mabry of the 3rd TX CAV as the "only known negro that served in the Confederate States army during the period 1861-1865 that is buried in Hopkins County, Texas." Really interesting. I don't know if this is common knowledge about the 3rd.
