By the regulations of the League, in cases where the United Council did not act authoritatively for the whole Confederacy, it appears that the separate tribes were not precluded from engaging in war; nor individual warriors prevented from taking up the hatchet, as inclination might lead them. Acting under these principles, some of the Six Nations fought on the side of the French, during the war of 1755 and 1762, including that part of the Senecas who had their seat north of the Ohio, and below Fort Duquesne; and some on the upper Ohio, now called Allegheny, united with them. From these considerations it is not at all improbable that CORNPLANTER, then a warrior of twenty-three years of age, was on the war path at BRADDOCK'S defeat. It was probably his first battle, as it was also the first in which our WASHINGTON was engaged. The Indians of the Ohio and the lakes were, at this period, more apprehensive of the encroachments of the Virginians and the English generally, than of the French. The former were accompanied by the land surveyor and the woodman's axe;[K] the latter had in their train only the engineer to build forts, and a commissariat which supplied the wants of the Indians, as well as their own. Hence, a portion of the Senecas, of the upper Ohio, were induced to take the side of the French. CORNPLANTER, with a portion of his tribe, probably formed a part of that martial array which we are told set forth from Fort Venango, at the mouth of Venango river, now called French creek, (Franklin, Pennsylvania,) for the forks of the Ohio, embarked in three hundred canoes and batteaux, and having eighteen pieces of cannon. [K] a few years later than this period the Virginians made great encroachments upon the boundary of the Indians. Lord DUNMORE and others, claimed large bodies of land north of the Ohio. The Indians, for a long period of time, claimed that the Ohio was the boundary between them and the whites. In 1773 Lord DUNMORE caused surveys to be made at the Falls of the Ohio; and lands in that region are now held under his warrants and surveys.
