Wouldn't that be the definition of a proxy war? However, even that claim is suspect. The Continental Navy was a joke and had zero effect on the war. The French fought a global naval campaign with the world's largest navy. They also supplied the vast majority of gunpowder, cannons, and muskets used in the initial years of the war, and landed several sizable armies. At any point in the conflict the loss of French aid would have meant instant defeat for the colonists. The French or French allies engaged in more or less continuous warfare for decades both before and after the American Revolutionary War.
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.
And do you know, I had started that reply with a fuller explanation, but reconsidered it as a waste of words. I had thought I had been fairly clear: the Continentals did not do most of the fighting, unless you choose to exclude whole categories of other fighting that went on before, during, and after the war.
