Robert Barnwell (December 21, 1761-October 24, 1814) was a South Carolina revolutionary and statesman who was a delegate to the Continental Congress and a United States Congressman. Robert was born in Beaufort, South Carolina. His education was by a private tutor after he had exhausted the resources of the Beauffort common school. But he interrupted this and entered the revolutionary war at the age of 16 as a private in the militia. In the maneuvering after the Battle of Stono Ferry, his company was camped on Johns Island in late June of 1779. A British surprise attack at night cut them up badly in an action known as the Battle of Mathews' Plantation. The sixteen year old Barnwell was wounded so badly that they stripped is gear and left him for dead. He was found in the field by a slave and taken to his aunt (Mrs. Sarah Gibbes) on her nearby plantation. She and her daughter nursed him back to health.
He returned to duty, rejoining the militia the next spring as a Lieutenant. He was just in time to be included with the prisoners when General Benjamin Lincoln surrendered Charleston on May 12, 1780. He was imprisoned on the transport ship Pack Horse until his exchange in June of 1781. He returned to militia service, and by the end of the war had risen to Lieutenant Colonel.
Back home in Beaufort, Barnwell was elected to the South Carolina house of representatives for 1787-1788. He was a delegate representing South Carolina in the Continental Congress in 1788 and 1779. He was returned to the state house for terms in 1790-1791, and 1794-1801, and in 1795 he served as speaker of that house.
In the spring of 1788 Robert was a delegate to South Carolina convention that ratified the United States Constitution. He was elected to one term in the U.S. House (1791-1793) for an at-large seat, but declined to run again. Beginning in 1795 he was the chair of the board of trustees for the new Beaufort College, and held that position for many years. He was elected to the state senate for 1805-1806, and was President of that body in 1805.
He died in Beaufort and is buried there in the churchyard of the St. Helena Episcopol Church. His son, Robert Woodward Barnwell, was a Senator in both the United States Senate and the Confederate Senate.
