This chapter unearths quartering on the North American borderland where colonists and Native Americans struggled to live alongside one another, especially in the backcountry between the Appalachian Mountains and the Mississippi River. The Quartering Act included provisions to extend the law to places that were not organized British colonies, although this enforcement largely failed. Colonists and speculators advocated opening the backcountry to colonization as a means of paying for quartering troops, while Indian superintendents and British officers sought to leave the region to Native Americans. Ultimately, neither side prevailed; the borderland persisted and quartering in the backcountry remained an unsolved problem.
