Numerous British fortifications were constructed in the 1750s along Lake Champlain, Lake George, and the Hudson River, all on the eastern edge of the colony of New York. Many of these positions were reoccupied twenty years later during the American Revolution. The author has conducted excavations for nearly thirty years at several of these forts and encampments, seeking to understand the strategies, provisioning, foodways, and building techniques employed by British Regulars and Provincial soldiers as they fought on the American landscape. These sites include Fort William Henry, Fort Edward, Rogers Island, and Fort George, each of which helped to open up the interior of the colony of New York to further settlement.
