Richard Henderson appears on a single miscellaneous abstract card, stating that he was released by the U.S. provost-marshal at Memphis, Tennessee, on August 13 (year not stated, but probably 1864). His unit was stated as Co. B, 1st Arkansas Infantry. He does not appear on the rolls of any Arkansas regiment.

He was probably an 1864 conscript who had deserted and had taken the oath of allegiance at Memphis. That's speculation, based on similar records of soldiers whose identity is known, but there's just no way to positively verify this man's identity from the available information.
