On May 2, Loyalist Maj. Patrick Ferguson and sixty American Volunteers marched to Haddrell's Point to attack the small fort that stood on a causeway that led to Fort Moultrie. The fort was about 150 yards from the mainland and was defended by Capt. John Williams and twenty soldiers of the SC 1st Regiment. Ferguson divided his force into two 30-man elements. One group would attack from the right and the other group would attack from the center. The British took the fort with the cannons from Fort Moultrie firing on them until dark. The British soon fortified the fort for a possible attack.

Allaire: "Tuesday, 2nd. Began to fortify Lempriere's Point. Maj. Ferguson, with a detachment of American Volunteers, marched down to Mount Pleasant, stormed and took possession of a little redoubt, located partly on the main, and partly on the bridge that leads to Fort Moultrie. This cuts off the communication from Sullivan's Island, and keeps them on their proper allowance. The Rebels ran off from the redoubt, though it was very strongly situated, after they fired about a dozen shot. "
