Lt. Thomas W. Harris of Company C, 12th Georgia Infantry, earned his Confederate Medal of Honor during the Battle of Chancellorsville. Date is listed as May 1-4, 1863.
Some basic info. The medal winner was selected by a vote of the men in his company after a victorious battle. Some units refused to select anybody and some would vote their entire company a medal, obviously in some sort of protest against the medal. But most appear to have followed the rules.
You are right. No medals were ever struck. A man was sent to Germany to have them struck but disappeared to unknown circumstance. By the time word got back to Richmond, medals were a luxury they couldn't afford. Myself, I take it as a real medal of honor. After all they were picked by their own comrades and who better to decide than they?
