Who won Franco-American Naval War?

The GERMAN EMPIRE (led by the Prussians). They swiftly and easily inflicted a most humiliating defeat on France. They paraded their triumphant army down the Champs-Élysées in Paris, and as the price of the war took the provinces of Alsace and Lorraine from France. France burned with embarrassment and thirsted for revenge and for the restoration of her lost provinces for the next forty years, helping to set the stage for WWI.
