Custer did not captured that flag at Williamsburg in May 1862. He was handed the flag from a officer to be turned into the cavalry HQ. Custer, upon being handed the flag, started back to HQ with the flag and a new story that HE captured the flag, lol.

That flag in question was either the 5th North Carolina Infantry flag or the 3rd Virginia Cavalry (1 Guidon Captured).

I agree with everyone that the only Virginia Infantry was BG. Wise's Va brigade. I believe the flag was either captured at Saylor's Creek or in some skirmish/battle before Saylor's Creek. Interesting guess.

Have a good day,
