Thanks for your reply but it's the first I've ever heard of such a thing. Natural Bridge in Tallahassee is quite a ways from Perry, and took place near the end of the war.
I've been referred to the state archives of Florida but they're closed today.
I will return with what I learn if anything.
I was told the event at Perry was described in an older version of the Official Florida State History, so I find it hard to credit your explanation until I've checked available sources.
Can you provide a source for your explanation?
