Join James Calaski at the Mahwah Museum on a lecture exploring Benedict Arnold, Major André, and the Plot to Surrender West Point!

Prepare for the definitive story of Revolutionary War betrayal!

This lecture dissects the stunning conspiracy between American hero-turned-villain Benedict Arnold and British Intelligence Chief Major John André. Together, they hatched the high-stakes plot to sell West Point—the strategic key to the entire American Revolution—to the enemy.

Trace the secret, desperate midnight meetings and coded correspondence between the two men. Explore André’s daring undercover mission and the agonizing moments of his capture—when the plans for the fortress were found hidden in his boot. This near-miss not only exposed Arnold as America’s most infamous traitor but directly sealed the tragic fate of the charismatic British spy.

Discover how one man’s wounded pride and another’s dedication to duty led to an act of treason that almost crushed the American cause. This is the pulse-pounding, human drama behind the treason that shook George Washington to his core.
