A war in 1763 between the English and American settlers along the Pennsylvania and Virginia frontier, and a confederacy of Delaware, Shawanese and Seneca Indians, led by Pontiac, a Shawanese chief. These Indians had been dishonorably treated by the settlers arriving after the capture of Fort Duquesne. They were, besides, incited to the attack by the French fur traders. In June of 1763 a simultaneous attack was made along the whole frontier; the trading posts between the Ohio and Lake Erie were taken and the settlers and English traders were scalped. The settlers retaliated by slaughtering the inhabitants of Conestoga, a body of Christianized Indians on the Susquehanna. General Bouquet invaded the Indian country by way of Pittsburgh, Bradstreet along the lakes. The war was thus brought to an end (1764). It was an afterpiece to the French and Indian War.
