George Washington (February 22, 1732 – December 14, 1799) was an American political leader, military general, statesman, and founding father who served as the first president of the United States from 1789 to 1797. Previously, he led Patriot forces to victory in the nation's War for Independence. He presided at the Constitutional Convention of 1787, which established the U.S. Constitution. The French detachment proved to be only about fifty men, so Washington advanced on May 28 with a small force of Virginians and Indian allies to ambush them. What took place, known as the Battle of Jumonville Glen or the Jumonville affair, was disputed, but French forces were killed outright with muskets and hatchets. French commander Joseph Coulon de Jumonville, who carried a diplomatic message for the British to evacuate, was killed.
