Indeed, among that select few who would "mutually pledge to each other our Lives, our Fortunes and our sacred Honor," it was well regarded that Carroll had rather substantially more to lose than most. But his fellow revolutionaries would see him as much more. John Adams wrote to James Warren in February 1776, on the eve of the Canada mission, that Carroll "continues to hazard his all: his immense Fortune, the largest in America, and his Life. This Gentlemans Character, If I foresee aright, will hereafter make a greater Figure in America. His Abilities are very good, his Knowledge and Learning extensive, I have seen Writings of his which would convince you of this. You may perhaps hear before long more about them."
