On Episode 6 of Legends & Lies: The Patriots, we met the man whose name would eventually become synonymous with treason.

When Nathan Hale is captured behind enemy lines and hung for treason, Benjamin Tallmadge is quickly recruited to take his place, and the Continental intelligence operation is back on track.

But when Washington’s capable and trusted general, Benedict Arnold, faces a court martial, the protégé betrays his mentor - offering up the crucial fort at West Point, along with Washington himself - in return for an officer’s commission with the Brits.

While Tallmadge is hot on Arnold’s trail - with proof of his treasonous plan - Arnold slips away - into a red coat and a place in history as America’s most infamous traitor.

On the next episode, Francis Marion leads a guerilla assault on the British - earning the nickname “Swamp Fox.” Make sure to tune into Legends & Lies: The Patriots on Sunday at 8:00pm ET on Fox News Channel!

Legends & Lies is narrated by executive producer Bill O'Reilly and produced by Warm Springs Productions, which is known for such programs as The History Channel’s "Mountain Men," Animal Planet’s "American River Renegades" and HGTV’s "Log Cabin Living."
