This cruel warfare, so damaging to the New York frontier settlements and so fatal to the Six Nations, was really part of a desultory conflict which raged at intervals from north to south along our whole western border, and resulted in the total overthrow of British authority beyond the Alleghanies. The vast region between these mountains and the Mississippi river--a territory more than twice as large as the German Empire--was at that time an almost unbroken wilderness. A few French towns garrisoned by British troops, as at Natchez, Kaskaskia, and Cahokia on the Mississippi river, at Vincennes, on the Wabash, and at Detroit, sufficed to represent the sovereignty of George III., and to exercise a very dubious control over the wild tribes that roamed through these primeval solitudes. When the thirteen colonies declared themselves independent of the British Crown, the ownership of this western territory was for the moment left undecided. Portions of it were claimed by Massachusetts, Connecticut, New York, Virginia, North Carolina, and Georgia, on the strength of their old charters or of their relations with the Indian tribes. Little respect, however, was paid to the quaint terminology of charters framed in an age when almost nothing was known of American geography; and it was virtually left for circumstances to determine to whom the western country should belong. It was now very fortunate for the United States that the policy of Pitt had wrested this all-important territory from the French. For to conquer from the British enemy so remote a region was feasible; but to have sought to obtain it from a power with which we were forming an alliance would have been difficult indeed.
