Frontier Defence on the Upper Ohio, 1777-1778 [EPUB ebook] 

But the barbaric enemy facing the frontier differed greatly from the well-equipped, well-drilled professional army from Europe that confronted the armed men of the tidewater. The stealthy foes of the border aimed their heaviest blows at the homes, wives, and children of the settlers; no life was safe from them, no person secure. Through long and bitter experience, the backwoodsmen had come to understand the art of defense by concentration within neighborhood blockhouses and log forts. But a new danger presented itself. The Indians were now guided and stimulated by the nation’s white enemies, so that to their native cunning were added the superior intelligence and more astute methods of the English. The situation soon became desperate.The British authorities at Detroit were especially active in urging the Indians to war against the Americans. Permissory orders to that effect were received by Lieutenant-Governor Hamilton early in June, 1777. With consummate skill he roused the barbarians to frenzy; under his stimulus they prepared to hurl themselves upon the American frontier. The invading parties were provided by Hamilton with proclamations prepared both by Governor Carleton and himself, calling on the Western inhabitants to submit to King George and take refuge within the British posts, where a land bounty would be given them for loyal service. This project was adroitly devised to mingle terror and mercy, in the hope that the colonists’ rebellion would speedily be crushed on the Western borders; and that the Easterners, finding themselves between two fires, would be obliged to yield. The effect of these proclamations, scattered by Indian raiders throughout the American backwoods settlements, was considerable. In some cases they were suppressed by American officers, but the Loyalist disaffection in the trans-Alleghany is largely attributable to this source.
