I am sure that there would have been a P.O.W. record made of the prisoners once Powell Clayton returned to Pine Bluff. And certainly orders transferring them to the Little Rock prison and points north. However I have not seen one. That is something that seems oddly missing in Trans-mississippi Union Army records are the P.O.W. records especially of Confederate P.O.W. prisons in Pine Bluff and Little Rock.
