Greene was born in Potowomut, Rhode Island, on July 27, 1742. Self-educated, he assumed the management of his family's iron forge in 1770. Soon afterward, he was elected to the General Assembly. He helped organize a militia unit, the Kentish Guards. He joined General Washington's staff in 1776. Within two years, he became the army's Quartermaster General. Succeeding Horatio Gates at the head of the army's final southern campaign, Greene engineered successes at Cowpens and Guilford Court House. His strategy pushed the British out of the Carolinas and Georgia, thereby saving Charleston and Savannah. After the war, Greene faced financial ruin when an army contractor whom he had underwritten defaulted on payments to the American government. His battlefield acclaim, however, prompted the state of Georgia to reward him with a landed estate, Mulberry Grove, where he died on June 19, 1786.
