The killing of Jane McCrea on July 26, 1777, on the outskirts of a village in the northern Hudson Valley, would unexpectedly rupture the British advance from Canada that was meant to crush the American Revolution in one knockout blow. On that day, twenty-five-year-old McCrea, an unremarkable person preparing for an impending marriage, was assaulted, scalped, and killed by a group of Native Americans in the employ of British general John Burgoyne. Though the murder was but one of many civilian deaths in a fierce war zone, McCrea’s killing had far-reaching consequences for each of the three major parties involved in the Northern Campaign of 1777.
