1750-1828 Thomas Pinckney had an equally distinguished career. Educated in England at Oxford and the Middle Temple like his brother Charles Cotesworth Pinckney, Thomas Pinckney was dubbed “the Little Radical” by his English schoolmates. When armed warfare broke out shortly after his 1774 return to Charleston, Thomas Pinckney became first a captain and then a major in the First South Carolina Continental regiment. His correspondence with his sister Harriott Pinckney Horry between 1776 and 1780 provides fascinating details of garrison duty, recruitment activities, the invasion of East Florida, the siege of Savannah in 1779, and his wounding and capture by the British in Camden, South Carolina in 1780. Simultaneous with his military activity Thomas Pinckney represented his Charleston parish in the South Carolina General Assembly (the lower house of the legislature) from 1776 until 1791, also serving as the state’s governor 1787-1789 and as president of the state’s constitutional ratifying convention in 1788. In 1792 George Washington appointed him the U.S. Minister to Great Britain, a post he held until 1796 during the difficult years following the 1793 renewal of conflict between England and France which so challenged American neutrality. Supplanted as lead diplomat in Great Britain by the appointment in 1794 of John Jay to negotiate Anglo-American differences (leading to Jay’s Treaty of 1795), Pinckney was appointed on a special mission of his own to Spain, where he successfully negotiated the 1795 Treaty of San Lorenzo, often known as “Pinckney’s Treaty,” securing for Americans an established boundary between the U.S. and West Florida and access to the port of New Orleans. This success led to his nomination by the Federalists for the Vice Presidency in 1796. Defeated by Thomas Jefferson, he was instead chosen in a special election in 1797 to the House of Representatives, where he served until 1801. During the War of 1812, he came out of political and military retirement to command the Southern Division of the U.S. Army. Agricultural experimentation was his passion; like his brother he was active in the South Carolina Agricultural Society, and on his several plantations on the South Santee River he implemented innovations in rice cultivation and animal husbandry. In 1825, he succeeded his brother as President General of the national Society of the Cincinnati. Contribute to the Wikipedia biography of Thomas Pinckney.
