As this battle comes to an end, Italian troops who had crossed the Alps are repelled by a very small French garrison at Menton, five miles inside the border. For this, Mussolini isn't given any part of France. He's left extremely embarrassed by the inability of his troops to break through French lines. German and French representatives negotiate a peace to be signed at the 1918 Armistice site at Compiègne inside the very same rail car (to be brought in from a French museum) where the WWI armistice was signed. Hitler declares the Battle of France officially over.
