Not only were mass killings not new, but the weapons used were not even always "arms." Before the Revolution, the British and colonists engaged in biological warfare against the Indians during the French and Indian War. The Indians were given blankets from a smallpox hospital in hopes of spreading the disease widely through the Indian population.
