Second Armistice at Compiègne
After the Second Armistice at Compiègne in June 1940, the Reich Interior Ministry produced a memorandum on the annexation of a strip of eastern France from the mouth of the Somme river to Lake Geneva, intended as a reserve for post-war German colonisation. The planned dissection of Switzerland would have accorded with this new French-German border, annexing the French-speaking region of Romandy into the Reich despite the linguistic difference.
