A vivid and timely re-examination of one of young America’s most complicated figures: the war hero turned infamous traitor, Benedict Arnold.

History remembers this proud, talented, and conflicted man solely through the lens of his last desperate act of treason. Yet the fall of Benedict Arnold remains one of the Revolutionary period’s great puzzles. Why did a brilliant military commander, who repeatedly risked his life fighting the British, who was grievously injured in the line of duty, and fell into debt personally funding his own troops, ultimately became a traitor to the patriot cause? Throughout, Malcolm weaves in portraits of Arnold’s great allies—George Washington, General Schuyler, his beautiful and beloved wife Peggy Shippen, and others—as well as his unrelenting enemy John Adams, British General Clinton, and master spy John Andre. Thrilling and thought-provoking, The Tragedy of Benedict Arnold sheds new light on a man—as well on the nuanced and complicated time in which he lived.
