According to Major B.D. Chenoweth (commanding 21st Texas Cavalry) during the Battle of Pine Bluff on Oct 25th, 1863 Carters Brigade also included B. D. Kie's Texas Cavalry Squadron/Battalion along with The 21st Texas Cav., Morgan's Battalion and Pratt's Battery.
Is there any reason to believe that McKie's was not a part of this Brigade during the Battle of Little Rock?
