January 16th, 1865, Union General William Tecumseh Sherman issued special field order number 15. This field order confiscated a strip of coastal land extending about thirty miles inland from the Atlantic Coast and stretching from Charleston, South Carolina, two hundred and forty-five miles south to Jacksonville, Florida. The order made this land into federal property. The land was then given mostly to emancipated peoples.
The field order was as follows…
“Special Field Orders No 15
