France and Britain both claimed the Ohio River valley. A larger French Canadian force expelled a British colonial crew building Fort Prince George near present-day Pittsburgh. Britain dispatched George Washington's Virginia provincial troops to protect the construction, while France sent Joseph Coulon de Jumonville to warn Washington that he was encroaching on French-claimed territory.
On May 28, 1754, Washington, alerted by Mingo chieftain Tanacharison, led a surprise attack on Jumonville's camp of 35 French Canadians in Fayette County, Pennsylvania. The ambush killed Jumonville and several of his men; most survivors were captured. The precise circumstances of Jumonville's death remained contested, with French accounts alleging assassination.
Washington retreated to Fort Necessity, where Canadian forces from Fort Duquesne compelled his surrender. The surrender document, written in French, contained language admitting Jumonville was assassinated, which France and Canada used to condemn Washington internationally. The incident, occurring while Britain and France were nominally at peace, escalated tensions that contributed to the outbreak of the Seven Years' War in 1756.
