“While in England,” Benjamin F. Butler wrote, “he was consulted in many cases involving intricate and important legal questions, and on one occasion in particular he was associated with Lord Chancellor Eldon, whose reputation, it is believed, was much enhanced by pursuing the advice and adopting the views of Mr. Van Schaack.” He was often asked by his fellow countrymen to help them secure remuneration from the British government for the losses they suffered as a result of the revolution. He rendered his services often and without compensation. Van Schaack gradually became disillusioned with the British government. In January 1780, he came to the conclusion that he no longer had allegiance to it. He wrote that he initially believed that British actions towards the American colonies were motivated by a need for “solid revenue,” but that he came to realize that “the real design was to enhance the influence of the Crown, by multiplying officers dependent on it. In short, to establish in the Colonies the system of corruption by which their government here is carried on.” Van Schaack came to believe that the British constitution, he had so admired, was no longer in existence.
