I find another Volunteer Company Cavalry with officers commissioned on 14 June 1861. This could be the same as the first company with new officers being elected.

W. C. Mitchell Capt.
A. L. Hudson, 1Lt
W. R. Coker, 2Lt
James C. Turnbo, 3Lt

I suspect this COMPANY C, 14TH (POWERS) ARKANSAS INFANTRY REGIMENT
