The desire of Whites to occupy Indian lands, and the constant rivalry between French and English traders for furs gathered by the Indians, led to many skirmishes and several bloody wars, all of which involved Indians on both sides. The Whites were determined to fight it out with each other-down to the last Indian. These battles culminated in the French and Indian War of 1763, which represented a disaster to many Indian groups in the northeastern part of the continent. In May, 1763, an Ottawa warrior by the name of Pontiac fell upon Detroit and captured the English forts, one after the other. Lord Jeffery Amherst... distributed among the Indians handkerchiefs and blankets from the small pox hospital at Fort Pitt-probably the first use of biological warfare in history.
