Early in the Revolutionary War, Major General Benedict Arnold built a reputation as a courageous commander. He was a favorite of George Washington’s. But he also revealed a fragile ego and a penchant for holding grudges. As the war went on, Arnold’s temper, ambition, and greed would turn him from hero to villain.

In this four-part series, American History Tellers explores the stories of America’s most infamous traitors -- the men and women who were charged, rightly or wrongly, with betraying their country. All of them paid a high price for their crimes. And all of them changed the course of our nation’s history -- starting with the man whose name is now synonymous with treason: Benedict Arnold.
