By the mid-18th century, British traders were rivaling French traders in the area. They had occupied a trading post called Loramie's Fort, which the French attacked from Canada in 1752, renaming it for a Frenchman named Loramie and establishing a trading post there. In the early 1750s George Washington was sent to the Ohio Country by the Ohio Company to survey, and the fight for control of the territory would spark the French and Indian War. It was in the Ohio Country where George Washington lost the Battle of Fort Necessity to Louis Coulon de Villiers in 1754, and the subsequent Battle of the Monongahela to Charles Michel de Langlade and Jean-Daniel Dumas to retake the country 1755.
