Germany, more than one million persons along the Franco-German border area (in the red zone) were evacuated. This area is called the " red zone " : it's the space between the Maginot-Line and the border and between the Siegfried-Line and the border. The Alsatians and Lorrainers were evacuated to the SouthWest of France and the people from the Saarpfalz and Baden were evacuated to the internal Gaue of Germany. These evacuations were aimed on one hand at giving free space for military interventions on the border zone and, on the other hand, at protecting populations from air and ground attacks .
