When 70-year-old Benjamin Franklin boarded the Continental sloop-of-war Reprisal in Philadelphia on October 26, 1776, for a month-long voyage to France, General George Washington‘s Continental army was losing the American Revolutionary War.
The hope and excitement spawned by the Declaration of Independence, announced just four months earlier, with Franklin among the signers, had been replaced by the dread of impending defeat in the face of the overwhelming military power of the British Army.
Franklin knew his mission was straightforward, if not simple. He would use his intellect, charm, wit and experience to convince France to join the war on the side of the fledgling United States of America.

It had lost a majority of its claim to North America, forced to cede to England most of its land there, including all of Canada.

It began providing covert support — beginning with badly needed gunpowder — in the spring of 1776. The Declaration of Independence was well received across France, and Franklin was warmly welcomed w
