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. In America, she became the great cause célèbre of the Revolution, the sympathetic female victim of the war symbolizing the righteousness of The Cause. In Britain, she was a human-rights tragedy that tarnished the polished surface of British honor and galvanized Whig politicians who shouted out her name in Parliament as an example of how low the nation had fallen. For Native peoples, recruited by both the British and the Americans, and caught in the middle of a war staged on ancestral grounds, McCrea's killing was the opening salvo in a vicious chain of bloody retribution that led to the disintegration of the venerable Iroquois Confederacy and the obliteration of Native homelands. After the war, the nightmarish image of a young Jane McCrea slaughtered on the New York frontier would obsess white Americans who came to fear Native peoples as irredeemable savages. Her murder would help justify the expulsion of Indigenous tribes and open the doors for an expansionary United States that was fully intent on transforming the American continent into its own image. The Killing of Jane McCrea: An American Tragedy on the Revolutionary Frontier by distinguished historian Paul Staiti undertakes for the first time a comprehensive investigation into McCrea's life, death, and especially her long and strange afterlife. Using both visual arts and written records, the author reassembles the scattered fragments to illuminate a historical terrain long since shrouded in misinformation, mired in controversy, and relegated to mythology. Coming into view is a major portrait of the persons, cultures, actions, and motives that fatally converged on that hot July morning in 1777.
