Key attacked a party of Tories
posted at Horn Creek under the command of a Captain
Clark; the Tories were defeated, their captain killed, and the
entire company captured and paroled. The Patriot band then
proceeded to Hammond's Mill, on the Savannah River,
where they attacked a British fort, broke up the mill, and took
away all of the enemy's provisions.
...
The mill occupied by the British was
the property of Colonel LeRoy Hammond, a noted
eighteenth century entrepreneur who had acquired important
real estate holdings north of Augusta. The mill was probably
the one at his Snow Hill property at the falls of the Savannah
River, a tract correspanding to the northwestern part of the
town of North Augusta in modern Aiken County.10
