I'm working on a work on the April 2, 1865 Hatcher's Run battle at Petersburg, Va and I can find nearly every Confederate flag captured and the Union soldiers who took them with the exception of one. I found out that Sgt. Francis M. McMillen of the 110th Ohio captured an unidentified Confederate flag tagged with WD No. 497 after the war, but I haven't been able to find out where and how he captured the flag or what it looked like to suggest a possible identification. I pretty sure it has to be a Tennessee regiment.
Thank you for your efforts.
