At 6.30 PM, French General Huntzinger returns to the railway carriage at Compiègne, site the 1918 Armistice. He and German OKW Chief General Keitel sign the 1940 Franco-German armistice. Article 20 states “French troops in German prison camps will remain prisoners of war until conclusion of a peace”. The French believe it is only a matter of weeks before Britain will also make peace with Germany. Instead, a million Frenchmen will spend the next 5 years as German prisoners. Hitler does not demand the French fleet, but Article 8 leaves the disposition of their warships uncertain, which worries the British. http://www.ibiblio.org/pha/policy/1940/1940-06-25b.html

This speech is heard more widely in France than the June 18 broadcast. http://fr.wikisource.org/wiki/Appel_du_22_juin?match=en
