News of American resistance probably struck Franklin like
a lightning bolt. It energized him, sending him into action. The
British had always known he was an advocate for American interests,
but they also respected him as a man of letters and science. He
was a man of the Enlightenment, an international figure. They may
not have also realized how much of a patriot he was. This must have changed
when Franklin made himself into a one-man propaganda army to fight
the Act. His opinions filled the British press; to most Britons
he became the symbol of American patriotism. In France, too, Franklin
came to symbolize America–homespun, intelligent, and wise. He was
our first and best diplomat.
It is difficult to pin down the precise moment when Franklin came
to believe that America should be independent of Britain. He predicted
American independence long before the war began, but at the time
of the Stamp Act he didn't support the idea. He, like many Americans,
held out hope that the differences could be resolved. He also knew
that if any single person in America or Britain would be able to
resolve the differences, it would probably be him.
