6. The Turn to Treason

In 1777, Benedict Arnold performed brilliantly in thwarting the British advance into upstate New York. He was instrumental in bringing about its defeat, which culminated in the British surrender at Saratoga, where Arnold fought courageously and was severely injured.
Crippled by his wounds, Arnold was put in charge of Philadelphia, where he took to socializing with loyalist families, as well as extravagant living, which he financed with questionable dealings that led to scandal. He also married a much younger woman, Peggy Shippen, who combined loyalist sympathies with spendthrift habits that soon put Arnold deep in debt. Between resentments and financial difficulties, he secretly approached the British to offer his services.
