 FACT: In the scene where the German army parades through Paris (June  1940) theyre marching under the Triumphal Arch and past the Tomb of  the Unknown Soldier (this is indicated in the scenes opening shot  with the eternal flame on the tomb). In fact, the Germans refrained  from marching through the Arch, as did de Gaulle and the Free French  in 1944. The German HQ wanted to avoid stirring up revulsion and  hatred, and no parade at all has marched there since the Unknown  Soldier was put to rest in 1920. They have all passed beside the  Arch (part of the symbolism of the Tomb is a wish for "no more  wars").
