The armistice established a modest demilitarized zone deep on the French side of the border, thus eliminating the Alpine Line. The actual Italian occupation zone was no more than what had been occupied up to the armistice. It contained 832 km² and 28,500 inhabitants, which included the city of Menton and its 21,700 inhabitants. Italy retained the right to interfere in French territory as far as the Rhône, but it did not occupy this area until after the Allied invasion of French North Africa in November 1942. In addition, demilitarized zones were established in the French colonies in Africa. Italy was granted the right to use the port of Djibouti in French Somaliland with all its equipment, along with the French section of the Djibouti–Addis Ababa railway. More importantly, the naval bases of Toulon, Bizerte, Ajaccio and Oran were also to be demilitarized.
