In a supplementary OKW order dated 10 September 1943, Hitler decrees on the establishment of further Operational Zones in Northern Italy, which were the stretch all the way to the French border. Unlike Alpenvorland and Küstenland, these zones did not immediately receive high commissioners (oberster kommissar) as civilian advisors, but were military regions where the commander was to exercise power on behalf of Army Group B. Operation zone Nordwest-Alpen (Northwest Alps) or Schweizer Grenze (Swiss Frontier) was located between the Stelvio Pass and Monte Rosa and was to contain wholly the Italian provinces of Sondrio and Como and parts of the provinces of Brescia, Varese, Novara and Vercelli. The zone of Französische Grenze (French Frontier) was to encompass areas west of Monte Rosa and was to incorporate the province of Aosta and a part of the province of Turin, and presumably also the provinces of Cuneo and Imperia.
