I keep hearing the French can't fight. I thought their naval victory over the British made Yorktown possible?

Yes but France has a rich history over war. Do you know who Napoleon is greatest General who ever lived, the only reason he had one defeat was because all major nation of Europe and Minor Nation's declared war on him that is why France is tiny. if napoleon would had won his defeat the only nations in the world would be united states and France. Napoleon was basically another Hitler but a good guy
