Hitler forced the French to surrender on the same site where Germans were forced to surrender in WWI
After Germany's decisive victory in the Battle of France in June 1940 during WWII, Germany essentially occupied France. When choosing the location for France's surrender, Hitler enlisted some poignant symbolism.
The Second Armistice was signed on June 22, 1940 at Compiegne Forest in France. This was the exact sight where Germany surrendered to France in WWI. Since this original surrender was a humiliation for Germany, Hitler saw this as an opportunity for revenge. He even decided to sign the armistice on the same rail carriage where the WWI armistice was signed.
Hitler then ordered the site to be demolished. And the rail car was brought back to Germany as a trophy of war.
