I suggest you order Col. Terry's service record file, mainly for the information contained in the following paragraph.
Col. Terry's service record file contains 12 cards including a rather large and detailed Regimental Morning Report broken down by Company, dated September 26, 1864, which appears to show some 600 men assigned, including a three page report, same date, at Bellville, reporting on the "Conditions of his Regiment."

March 1865 Regimental Return notes they were stationed in Austin Co., Col. D. S. Terry was appointed and confirmed by election, July 6, 1864, assigned to the 2nd Brigade, Maxey's Infantry Division, April 1865
His card contains this information regarding the regiment:
Terry's Regiment Texas Cavalry was organized and mustered into the service of the Confederate States about July 6, 1864, with ten companies, A to K, which were composed principally of former members of the Texas State Troops. It was dismounted in the early part of 1865. Company A was formerly Company F, 37th Regiment Texas Cavalry, which became an independent company about March 1864 and was assigned to this regiment July 6, 1864. Captain R. H. D. Sorrell's Company was first assigned to Griffin's Battalion Texas Infantry as Company G, then to this regiment and subsequently to Baylor's Regiment Texas Cavalry as Company I.

Attached to the Trans-Mississippi, the unit was ordered to Calcasieu Pass, Louisiana, then was active in numerous conflicts in Arkansas. Later it moved to Texas and was placed on commissary duty and disbanded in the spring of 1865. Its commanders were Colonel David S. Terry, Lieutenant Colonel S. H. Brooks, Major J. M. Evans.
