His record is confusing. I’ve copied the basic information on each of the cards in his two files

I would suggest you procure his Compiled Service Records through a service provided by these message boards. Contact the webmaster at: webmaster@history-sites.com

There are two different files, with cards under 2nd (Duke’s) Kentucky Cavalry and Morgan’s Men, Kentucky

It appears he was discharged, then why was he captured? We do know however, that the Yankees frequently termed those they detained as deserters.

Note, his regiment was stationed near McMinnville, Tenn. when he was taken prisoner January 27, 1863.
