I read from curriculum materials (Many a Weary Banner: The Flags of Appomattox) that the NPS offers to teachers that there is a letter and snipets of a flag that purports to be R.E. Lee's HQ flag that was never surrendered but cut up among the staff officers. It states:

"This remnant of General Lee’s headquarters flag was cut off by Capt. Edwards, Assistant Ordnance Officer in the Confederate Army. According to the accompanying letter, following the Surrender, the flag was divided up among the officers on the staff so as to prevent its desecration at the hands of the enemy & kept as a memento".

Is this the same flag that the MOC has or was that flag replaced by a Second National flag?
