The 16th was a West Virginia outfit. I would assume that he never returned to his command and along with other members of the unit,
turned themselves in for parole at Chaleston in May/June, 1865. I haven't been able to locate a history which shows their location at war's end.

Their Colonel did along with another soldier I found. I did not go any further.

On February 15, 1864, Col. Milton J. Ferguson [16th Virginia Cavalry] and 39 of his men were captured on Laurel Creek in Wayne County by Col. George Gallup and the 14th Kentucky Infantry. Ferguson soon found himself back at Camp Chase for a second stint, and was later sent to Fort Delaware and then on to Hilton Head Island, South Carolina before he was finally exchanged in late 1864. He served out the balance of the war, and was paroled at Charleston, West Virginia at war’s end, May, 22

Andrew Jackson Bowman, 16th Virginia Cavalry, was paroled at Charleston, West Va. June 23, 1865
