Knowing nothing about this, I wonder if he was captured and taken off to perhaps Little Rock.
I know Little Rock had a Union Prison after Little Rock fell in September of 1863, and that was where my ancestor,
Fielding Price was taken when he was captured in Nov. of 1864 dying there on Feb. 1, 1865 of small pox.
I seem to think that it was used as a prison by both sides, but I could be very wrong, depending on who was in
control at the time. .
My ggg uncle Solomon Moore with the 36th Arkansas CSA was also captured at Helena on July 4, 1862. Moore was
shipped north never coming home even though he was recorded as being still alive when the war ended.
Lots of questions are still floating around relating to the Civil War.
Good luck in your search for information.
