Fort Tonyn

Fort Tonyn, named for General Patrick Tonyn (East Florida's Royal Governor at the time of the American Revolution), was located in present-day Nassau County, Florida, near the hamlet of Mills's Ferry. The fort was unremarkable in its day, seeing little action. It is remembered chiefly because it served as a way station in the only substantial campaign Florida saw during the Revolution. General Robert Howe camped there with some 400 men on June 28, 1778, at the same time that Colonel Elijah Clarke led his troops to defeat at the Battle of Alligator Bridge.

The fort is believed to have existed as late as the War of 1812.
