I've heard quite a bit of talk of a massacre of the residents of the town of Perry in Taylor county Florida in either late 1864 or 1865.
A Union force from New Orleans landed somewhere in the Bend Bend area of the Gulf coast and began moving north on the state capital at Tallahassee. When they reached Perry the residents of the town resisted, and a general massacre of them is said to have taken place.
Apparently the commander of the Union force was so dismayed by the action that he abandoned it and returned the way they had come.
The Union force was then attacked by partisan Confederate forces and withdrew back to their landing place on the coast and were evacuated by ship.

Can any provide any documentation of this event?
