Thanks to the gentleman who emailed me regarding Capt McMillan being from Putnam Co. I tried emailing back but it failed. It was mentioned that he was killed two weeks after joining the 4th Tenn Cav. I have his Colt Navy pistol that is engraved with Lt. J.M. McMillan, 8th Tennessee Cav. However, records don't show him as being with the 8th. I know that the 13th was known in the field as the 8th, and that it recruited in the area where McMillan later joined the 4th. Any information regarding this would be deeply appreciated.
