Mike,
It is not incumbent upon me to prove that you are wrong.
It is incumbent for those making a claim to prove that claim.
So far you have failed to do this.
The foremost flag researchers in this country have seen the evidence
presented by the Citadel proponents. None of these people have been
convinced of the correctness of your speculation.
Keep looking.

Ken
P.S. Does anyone have access to the Compiled Service Record
of Williard Baker of the 20th Iowa?
Can they provide a transcript of it?
