When 18-year old beauty Peggy Shippen met ‘the bravest American’ Benedict Arnold, sparks flew. He was the leading revolutionary in the 13 colonies of the embryo United States. She was the loyalist daughter of a Philadelphia judge. Their relationship would determine the future of those states and, with it, the future of global politics.

Benedict Arnold was ‘as brave a man as ever lived’, according to one of the men who fought with him at the Battle of Saratoga. Yet Arnold was subjected to a court martial, a campaign against him in the Philadelphia press and denied the money owed to him by Congress.

After Peggy Shippen married Benedict Arnold, they began a secret correspondence with the British spymaster John André, the handsome and sophisticated army Major who once flirted with Peggy in Philadelphia.

Together, they formed a plan to surrender West Point on the Hudson River, described by rebel general George Washington as ‘the most important post in America’, to the British army and bring the revolution to an end.
