The Colleton family was the only one of South Carolina's original proprietors to establish a family seat and residence there. Sir John Colleton granted the twelve-thousand-acre Barony to his three sons, Peter, Thomas, and James, and James served as governor from 1686 to 1690. Peter's share on the west branch of the Cooper River passed through successive generations to the Honorable John Colleton, who came to reside in South Carolina in 1726, and between 1730 and 1740 a massive brick mansion and extensive plantation buildings were constructed nearly a mile west of the river. The plantation later passed to Sir John Colleton, who sympathized with resistance to England's unjust laws but did not support full independence, and who was buried at St. John's Church, Berkeley, in 1777. Fair Lawn Barony included the sites later known as Stony Landing, Old House, Gippy, Lewisfield, Exeter, Moss Grove, Fairfield, and Ellory's, and all of present-day Monck's Corner and Pinopolis lay within its bounds. During the Revolutionary War, the fortified Colleton mansion and a separate redoubt near Stony Landing on Biggin Creek swamp served the British as an operating base, communications center, supply depot, and hospital. Placed at the head of the Cooper River along the plantation avenue from the landing to the mansion and main public road, Fort Fair Lawn became the most significant British outpost between Charles Town and Camden, protecting troop movements, deployment, and intelligence lines in the South Carolina interior. Fair Lawn was involved in Lieutenant Colonel Banastre Tarleton's attack on General Isaac Huger at the Battle for Moncks Corner on April 14, 1780, and the redoubt was built by the British in the summer of 1780. It supported British operations against Brigadier General Thomas Sumter's attack on Biggin Church on July 16 and 17, 1781, and from late August to mid-November 1781 it was a key post for movement to and recovery from the Eutaw Springs battlefield. In the week of September 9 through 12, Brigadier General Francis Marion, Lieutenant Colonel Henry "Light-Horse Harry" Lee, and Captain Wade Hampton harassed the British post after the retreat from the Eutaws. On November 17, 1781, Colonel Hezekiah Maham, Colonel Isaac Shelby, and Colonel John Sevier, sent by Marion, attacked Fair Lawn Plantation; Maham judged the redoubt too formidable and too costly to assault, so the attackers charged the fortified Colleton mansion half a mile west and captured it, taking three hundred stands of arms, other stores, medical parolees, and seventy-six prisoners. The action also involved the removal of twelve British convalescents to the fort, and Fair Lawn was further marked by a British summary court-martial in April 1780 over harassment of the Colleton women and by the burning of the mansion hospital in November 1781, which became a military scandal. The British evacuated Fair Lawn by late 1781. The earthwork fortification survives in remarkable condition, with parapet walls up to two meters high and a surrounding moat still present, and it is one of only two extant Revolutionary War redoubts in South Carolina.
