Mr. Biggs,
Thank you very much for your information.
The twenty-five (25) flags that were mentioned by the 12th GA soldier would cover the infantry units in Jackson's Army.
Three regiments would have already received the silk battleflag at Centreville: 1st MD, 10th & 13th VA.

How recent is the discovery of the information from the 12th GA soldier? Who was he?

Again, thanks.
