Governor Dinwiddie launched another expedition. Colonel Joshua Fry commanded the regiment with his second-in-command, George Washington, leading an advance column. On May 28, 1754, Washington's unit clashed with the French in the Battle of Jumonville Glen, during which 13 French soldiers were killed and 21 were taken prisoner. After the battle, Washington's ally, Seneca chief Tanaghrisson, unexpectedly executed the French commanding officer, Ensign Joseph Coulon de Jumonville. The French pursued Washington and on July 3, 1754, George Washington surrendered following the Battle of Fort Necessity. These frontier actions contributed to the start of the French and Indian War (1754–1763), or, the Seven Years' War, a global confrontation between Britain and France fought in both hemispheres.
