Violence in Kentucky increased with the outbreak of the American Revolutionary War (1775–1783). American Indians who were unhappy about the loss of Kentucky in treaties saw the war as a chance to drive out the colonists. Isolated settlers and hunters became the frequent target of attacks, convincing many to abandon Kentucky. By late spring of 1776, Boone and his family were among the fewer than 200 colonists who remained in Kentucky, primarily at the fortified settlements of Boonesborough, Harrodsburg, and Logan's Station.
