Having succeeded in ingratiating himself into the good will of the Shippen family, Arnold won the affections of Margaret (“Peggy”) Shippen, the young and accomplished daughter of Edward Shippen, afterward Chief Justice of the State, who became his second wife. Owing to a recent wound received under circumstances which would alone have established a claim to grateful remembrances, had not his subsequent extraordinary defection obliterated his name from the roll of his country’s heroes, Arnold during his marriage ceremony was supported by a soldier and when seated his disabled limb was propped upon a camp stool. These wounds may perhaps have made him more interesting to the lovely but unfortunate bride. At all events, her “hero,” except for his character for extravagance, was at that moment regarded with a share of public favor, if not with any feeling of popular affection. He had rendered “some service to the State,” and was distinguished for gallantry among the bravest of the land. It is as unjust as vain to urge, as some have done, in palliation of his stupendous crime, the fashionable and expensive propensities of his beautiful and accomplished wife. That she was addicted to displays of wealth inconsistent with the spirit of her time and the condition of public affairs may not with propriety be questioned; but no external influence can move a truly great and honorable mind and heart from a fixed purpose of patriotic or social duty. When a mob was formed which gave out an intention to assault the house of Hon. James Wilson, which became known as “Fort Wilson,” and assault his person, it was a day of great excitement in Philadelphia. Wilson’s friends gathered around him and prepared to defend him as best they could. In the meantime, the mob and militia assembled on the commons, while a meeting of the principal citizens took place at the Coffee House. The mob began its march from Arch above Fifth Street. General Arnold came to repress the mob, but he was so unpopular they stoned him. Arnold’s conduct had given great offense to many of the active supporters of the American cause, which involved him in a quarrel with the authorities of Pennsylvania, and February 3, 1779, the Supreme Executive Council ordered the Attorney General of the State to prosecute General Arnold for illegal and oppressive conduct while in command of the military in Philadelphia. Active among those who urged an investigation of the charges was General Joseph Reed, President of the Council. A copy of the charges was presented to General Arnold, but he did not care to meet them, and under pretense of attending to his duty, “fled from the inquiry.”
