According to Wikipedia, Bayport has a population of 36 at the mouth of the Weekiwachee River, by Tampa. It started in the 1850s as a cotton and supply port. By 1863, the larger ports on Florida's Gulf coast had been closed and small rivers like the Weekiwachee became important trade routes and drew Union attention.
Eleven blockade runners were captured here between 1862 and 1865 and several skirmishes between Union and Confederate forces took place.
A Confederate battery can still be seen at the point north of Bayport's fishing pier at the mouth of the river.
