Under the definitive treaty of peace between Great Britain and the United States, the dominion of the former over Minnesota East ceased, but that of the United States government did not immediately supervene. Virginia under her charter of 1609 had claimed the whole Northwest, and her army, commanded by General George Rogers Clark, had in 1779 established her power in the Illinois country. Three years later the county of Illinois was created and an executive appointed by Governor Patrick Henry. The act of Congress of March 1, 1784, accepting the cession of her northwestern lands, amounting to a concession of colorable title, ended Virginia’s technical government in Minnesota East. From that date to the passage of the Ordinance of 1787 (July 13) this region remained unorganized Indian country. This great ordinance made it part of “the Northwest Territory” and gave it a written constitution. But this was nugatory for the reason that although Great Britain had in form surrendered the territory in the treaty of 1783, she continued her occupation for thirteen years longer. Her pretext for maintaining her garrisons at Detroit, Mackinaw, Green Bay, and elsewhere was the failure of the United States to prevent the states from confiscating the estates of loyalists and hindering English creditors from collecting their debts in full sterling value, as provided in the treaty. The actual reason was an expectation, or hope, that affairs would take such a turn that the whole or the greater part of the Ohio-Illinois country might revert to England. A new British fort was built on the Maumee River in northwestern Ohio in 1794. The surrender of this to General Anthony Wayne after the battle of Fallen Timbers, in August of that year, has been regarded as the last act in the war of the Revolution. By the Jay treaty it was agreed that the western posts should be given up to the United States, and on or about the 12th of July, 1796, the British commanders hauled down their flags and marched out their garrisons.
