I know it seceded, and there were a few forts that stayed in Union hands, but that's about it. Were there any major battles in Florida? How did it fare from 'devastation' perspective? How committed to the CSA was it?

John Milton, governor of Florida, shot himself while in office at the end of the Civil War, believing, “death would be preferable to reunion”.
