Benedict Arnold committed treason— for more than two centuries, that’s all that most Americans have known about him.

Yet Arnold was much more than a turncoat—his achievements during the early years of the Revolutionary War defined him as the most successful soldier of the era.

Today’s guest is Jack Kelly, author of “God Save Benedict Arnold: The True Story of America’s Most Hated Man.” We look at Arnold’s rush of audacious feats—his capture of Fort Ticonderoga, his Maine mountain expedition to attack Quebec, the famous artillery brawl at Valcour Island, the turning-point battle at Saratoga—that laid the groundwork for our independence.

Arnold was a superb leader, a brilliant tactician, a supremely courageous military officer. He was also imperfect, disloyal, villainous. One of the most paradoxical characters in American history, and one of the most interesting.
