Re: A revisit with the 7th Cavalry Standard
I believe the flag in the photo of Sheridan and his generals was the official HQ flag of the Cav Corps of the Army of the Potomac. This was a blue flag with crossed white sabers and a red "C" superimposed on the sabers. Sheridan's personal flag had no sabers. He used a red over white swallow tail flag with a white star on the red and a red star on the white.
