In the meantime, a series of events had happened in the Ohio valley which set the New World on fire. Céloron de Bienville had indeed staked out his boundary line, but the new Governor of Quebec, the Marquis Duquesne, saw clearly that a line of bayonets was the only limit which English expansionists would respect. Accordingly, a strong French force marched into the troublesome valley, and established themselves at a new post called Fort Le Boeuf. The report of this incursion was evil news for Governor Dinwiddie of Virginia, the most diligent and watchful of the thirteen governors of the English colonies. Having never ceased to regard Lake Erie as a northern boundary of British territory, this latest invasion on the part of the French was to him beyond endurance, and he forthwith despatched the Adjutant-General of the Virginia Militia to deliver England's protest to the French commander. The messenger was a tall handsome youth of twenty-one, and the message was the first important commission of George Washington. [Illustration: Plan of the CITY OF QUEBEC 1759] [Illustration: MAJOR-GENERAL SIR ISAAC BARRE (Paymaster of Wolfe's Forces)] In spite of the studied courtesy of his reception by Legardeur de Saint-Pierre, the English envoy saw the hopelessness of his errand, and hastened back to Williamsburg with his report. Dinwiddie thereupon resolved to meet force with force. Although he scarcely persuaded the disunited colonies to take a serious view of the French invasion, he was presently able to send George Washington back again into the Ohio valley at the head of a company of regulars and three hundred soldiers of the Old Dominion. Meanwhile the French had seized an English trading-post at the junction of the Ohio and Monongahela rivers, and named it Fort Duquesne. This post was Washington's immediate objective, and as he approached it his advance-guard met a French reconnoitring party under Jumonville, sent, it is alleged, by the commandant of Fort Duquesne to warn the Virginians off French soil. The precise purpose served by this handful of Frenchmen has never, however, been fully determined. Jumonville's movements are certainly hard to reconcile with the theory of a peaceful mission, and to Major Washington they certainly appeared hostile. In the sharp fight which followed, Jumonville and nine others were killed, while of the remaining twenty-three only one escaped. By the English, the affair was described as a successful skirmish, by the French as the "_Assassinat de Jumonville_"; for all it meant precipitation of the death-struggle for North America.
