The Frenchman had done but little fighting for this region. He swore brotherhood with its savages, traded with them, intermarried with them, and explored the Middle West; but he left the wilderness much as he found it. Some six or seven thousand French people in all, about Detroit and Vincennes, and in the Illinois country, and scattered among the Indian villages of the remote lakes and streams, held possession when George Washington reached the site of Pittsburgh, bearing Virginia's summons of eviction to France. In his person fate knocked at the portals of a "rising empire." France hurried her commanders and garrisons, with Indian allies, from the posts about the Great Lakes and the upper Mississippi; but it was in vain. In vain, too, the aftermath of Pontiac's widespread Indian uprising against the English occupation. When she came into possession of the lands between the Ohio, the Mississippi, and the Great Lakes, England organized them as a part of the Province of Quebec. The daring conquest of George Rogers Clark left Virginia in military possession of the Illinois country at the conclusion of the Revolutionary War; but over all the remainder of the Old Northwest, England was in control. Although she ceded the region by the treaty which closed the Revolution, she remained for many years the mistress of the Indians and the fur trade. When Lord Shelburne was upbraided in parliament for yielding the Northwest to the United States, the complaint was that he had clothed the Americans "in the warm covering of our fur trade," and his defense was that the peltry trade of the ceded tract was not sufficiently profitable to warrant further war. But the English government became convinced that the Indian trade demanded the retention of the Northwest, and she did in fact hold her posts there in spite of the treaty of peace. Dundas, the English secretary for the colonies, expressed the policy, when he declared, in 1792, that the object was to interpose an Indian barrier between Canada and the United States; and in pursuance of this policy of preserving the Northwest as an Indian buffer State, the Canadian authorities supported the Indians in their resistance to American settlement beyond the Ohio. The conception of the Northwest as an Indian reserve strikingly exhibits England's inability to foresee the future of the region, and to measure the forces of American expansion.
