We beat England, along with their "Hessians", at the battle of Saratoga before France declared war on Great Britain and allied itself with the new nation. Spain and the Dutch later declared war on England.
Forgot to mention: The British also hired 20,000 African-Americans to fight for them in America during the Revolution. This brings the number of non-English troops fighting for the Crown to well over 60,000.

If I think of any more, I'll update.
