The Key of the Harbor

“On the second of March, I was ordered down to Sullivan’s Island, to take command; where we were building a large fort sufficient to contain 1000 men. As this was looked upon as the key to the harbor; a great number of mechanics and negroe laborers were employed in finishing this fort as fast as possible, we having got certain intelligence that the British were preparing, at New York, for an expedition against Charlestown.”
