In August 1777, a British force under Brigadier General Barry St. Leger marched through the Mohawk Valley expecting to brush past a rotting frontier post at the Oneida Carry. Instead it found Fort Stanwix rebuilt and held by more than 700 Continental regulars under Colonel Peter Gansevoort. This episode traces how felled trees, a raid on empty camps, and a single well-told lie collapsed the siege from the inside.

We follow the bloody ambush at Oriskany, Marinus Willett’s sortie that looted the besiegers’ camps, Gansevoort’s defiant refusal to surrender, and Benedict Arnold’s ruse using the captured loyalist Han Yost Schuyler to spread word of a 3,000-man army. The result rippled straight to Saratoga, the French alliance, and the turning point of the American Revolution.

• Why the Oneida Carry made Fort Stanwix the hinge of Britain’s 1777 pincer strategy
• How an abatis of felled timber stalled St. Leger and let a supply convoy slip into the fort
• Why the Battle of Oriskany and the camp raid fractured Britain’s alliance with Seneca and Mohawk warriors
• How Benedict Arnold’s ghost army bluff triggered a panicked British retreat without a shot fired
