From 1933 to 1935, during the period of the Abyssinian War, intercept stations of the Army High Command, monitored Italian traffic without cessation. During the Abyssinian War, the intercept stations and the Wehrmacht cipher bureau were able to follow all Italian traffic very closely because, with one exception, it was in possession of all Italian codes. The strength, organisation, and locations of the Italian peacetime army was accurately known, and it was possible to keep abreast of the movements of each unit. The SIS also possessed a roster of all Italian officers, from Commander-in-Chief, Benito Mussolini, down to the youngest second lieutenant. Locations, strength, and armament of the Italian Colonial Troops were also known in detail.
