Just came across the 5th Tenn Cav (Union) flag. $35,000

Hope that link works!
PS. The Chancellor Park Rangers believe the 4th Ohio Infantry Regiment captured the 22nd Va Battn's Flag. I see the 16th North Carolina was to the left of the 22nd Va Battalion and facing east. They were right behind BG. Thomas Ga Brigade.
Have a good weekend,
