This was in the early fifties, and the fort was hardly transformed before the rifles of George Washington's men were heard from the eastern barriers disputing the claim of the French to the Ohio country. Jumonville, who was slain among the rocks of the Laurel Mountains, in the Alleghanies (killed in the opening skirmish of the final struggle), had a young brother, Neyon de Villiers, a captain in Chevalier de Macarty's garrison at Fort Chartres; and eastward he hastened, up the Ohio, to avenge his brother's death. "M. de Wachenston" (as the name appears in French despatches) was driven back, and so the "Old French War" in America began. It was from this mid-continent fortress and its fertile environs that help in arms and rations went to the support of that final struggle along the mountains and lakes, even as far as La Salle's old Fort Niagara, where the valiant Aubry, at the head of his Illinois expedition, fell covered with wounds and many of his men were killed or taken prisoners. That was about all that one in the interior of the valley heard of the battles of the Seven Years' War out upon its edges. What gives peculiar interest in this fortress to us to-day is that it was for a little time the only place in North America where the flag of the French was flying. All New France had been ceded by the treaty of Paris in 1763, but the little garrison of forty men still held Fort Chartres. Pontiac and other friendly Indians intercepted all approaching English forces till, in 1765 (two years after the treaty of Paris and the cession of Canada and all the valley east of the Mississippi), St. Ange, the commander, announced to Pontiac, friendly to the end, that all was over, that "Onontio, their great French father," could no longer help his red children, that he was beyond the sea and could not hear, and that he, Pontiac, must make peace with the English. Then it was that the forty- second Highlanders, the "Black Watch," were permitted to enter the fort and to put the red cross of St. George in place of the fleur-de-lis. And so it was at Fort Chartres that the mighty struggle ended and that the titular life of the great empire of France in the new world actually went out. The river, seemingly sentient, and still French, as I have said, soon swept away the site of the village outside the fort; and when the English had begun to look upon this as their permanent headquarters in the northwest--this fort, which Captain Pittman had reported to be the best- built fort in America--the still hostile river rose one night, and with its "resistless flood" tore away a bastion and a part of the river wall, then moved its channel away, and left the fort a mile inland.
