British forces on the frontier of eighteenth-century North America faced potent adversaries in the form of French armies and forts, often accompanied by their Native American allies. The lack of easily traversed roads could have been a logistical nightmare, but armies were able to overcome this by travelling along the waterways that formed a natural transportation corridor between Canada and New York City. Numerous British fortifications were constructed in the 1750s along Lake Champlain, Lake George, and the Hudson River north of Albany, and many of these positions were reoccupied twenty years later during the American Revolution. Strategically positioned forts were accompanied by large seasonal encampments, by specialized structures that included blockhouses and hospitals, and by battlefields where clashes occurred. Archaeologists have conducted excavations at many of these sites, seeking to understand the strategies, provisioning, and building techniques employed by British Regulars as they fought on the American landscape.
