I appreciate you taking the time to help me out!!
Since I posted my message, I found a great source for POW records on Ancestry.com, including an entry for my Thos. R. Duncan, at Gratiot Street Prison. It mentions him being captured in Benton County, on Oct 15th. Rank: Private. Regiment: "Recruit." Exchanged Dec 12th, 1862.
I'm unclear what "recruit" refers to, unless he was unassigned to a regiment. There seem to be several officers and enlisted men with this designation, but no common denominator. – ‘Will be interesting to research.
Jim, your thought about him serving under Col. J. Vard Cockrell, at Lone Jack, seems plausible. I have considered this angle, but would feel better if the names were just a bit more similar… Maybe, he was new the command and didn't remember Cockrell's name correctly? – I’m keeping all options on the table for now.
Any idea what counties the men from Cockrell’s Cav came from? Thomas R Duncan was originally from Calloway Co., MO then, a few years before the war the family moved to Benton Co.
FWW, According to the Soldiers and Sailors System (SSS) site, the only other soldier in Corcoran’s Reg, was Sgt. B. F. Hogue.
Also, the only Corcoran’s listed in the SSS were Privates in either the 1st or 10th Mo Infantry…
