Earlier quoted context omitted.
"with the help of the French" is an understatement. It was better described as a proxy war between Britain and France.
The war was almost certainly unwinnable without French loans, arms, and naval support, but the bulk of the fighting was done by the Continentals.
It's most accurate to say that the American Revolution was a notable but not decisive campaign in the Second Hundred Years War. Americans blow their participation in the conflict wildly out of proportion -- patriotic textbook revision has produced an epic creation mythology. Panamanian schools seem similarly to omit the role of the US in the creation of that country. It's not just that history is written by the winners, it's that it's continually rewritten by the winners.
