I have one reference that states that the remnants of the regiment were "destroyed' in an engagement at Lewisburg, Arkansas on February 12, 1865,
Another source that states "The unit skirmished in Arkansas and on May 28, 1865, requested from the Federals terms under which it could surrender".
Bryan Howerton lists the 10th Arkansas Mounted Infantry—Col. Allen R. Witt (Jacksonport) as one of the units which surrendered at Jacksonport under General M. Jeff Thompson.
