“You never succeeded in invading the US. We sent your Mercenaries packing along with the british and you never took any land from us.” I am a little bit late in the debate, but correct me if I am wrong: Wasn’t around 7000 French soldiers along side the 7500 American soldiers in Yorktown. Wasn’t the French fleet which defeated the British fleet? The American without the French Siege Artillery would have bib problem to take the town. And without the French fleet, they would have been unable to protect their main towns.
