aka Tar Bluff, aka Chehaw Neck.

Near Beaufort – Lt. Col. John Laurens in command of a detachment of Continentals attacked British Regulars making a landing at the ferry. Lt. Col. Laurens routed the British, but while pursuing them he was drawn into an ambush and killed.

This detachment found 300 British Regulars and 200 Loyalists with 18 vessels already on the Combahee River. Brig. Gen. Gist sent part of his forces across the Combahee Ferry to drive them off, and sent Lt. Col. Laurens downriver to intercept any that might attempt to flee.

At Tar Bluff, Lt. Col. Laurens threw up a hasty earthwork with fifty men and a howitzer. This small group stopped the British flotilla. British Maj. William Brereton arrived and quickly dislodged the small Patriot group, killing Lt. Col. Laurens and several of his men. The British forces escaped Brig. Gen. Gist's follow-up.

Maj. Brereton and his flotilla went up St. Helena Sound into the Coosaw River. On September 2nd, Brig. Gen. Gist set up an artillery post at the Port Royal Fery and drove off Maj. Brereton - the last major action in what is now Beaufort County of the war.
