France did surrender. The rest of the allies expected the government to detach to North Africa and continue the war from there. Instead they surrendered and more french troops fought for the Axis than they did for the Allies. Hitler had expected the invasion of france would claim a million german casualties, but he faced a demoralised army and took paris in six weeks with less than 50,000 dead or missing.
The French ministry of defence figures that around 200,000 military deaths during the whole war, including metropolitans and colonials, as well as resistance fighters; a fourth to a third of their casualties occured during the Battle of France. While the French can certainly claim to be a warlike people that has many times destroyed its neighbours, during World War II they fought poorly and surrendered promptly.
