Anthony, is this Slemons's 2nd Arkansas Cavalry Regiment that became McMurtrey's 18th Arkansas Cavalry Battalion? Was Slemon's unit also designated as the 3rd Trans-Mississippi Cav? I think I have all of the Trans-Mississippi Rifle Regiments, but I do not have a complete list of the Trans-Mississipii Cavalry Units. Is there an order from Price that cerated all of the "Trans-Mississippi" designations? Does anyone have a copy?
