I really think he was talking about the Battle of Marianna but for some reason thought it was in Perry. The account is just too much like Marianna:
1) Church burned with Confederates inside
2) Allegations of a massacre
3) U.S.C.I. troops involved.
4) Local citizens turning out to fight
5) Prisoners were taken to New Orleans.
There are accounts like that about Marianna in almost all of the old Florida history books.
