Wire tapping Eavesdropping
German armed forces of WWII
During World War Two (WWII), the German armed forces (Wehrmacht) — and the
Army (Heer) in particular — used wired analogue telephone lines, also known
as land-lines, whenever possible. Much of their communications ran over the
existing telephone lines in Germany and in occupied countries like France,
the Netherlands and Norway. In addition to this, ad-hoc field telephone
configurations were used, which were sometimes linked to the public switched
network (PSTN).
As the Germans trusted nobody, not even their own officers,
security services like the Gestapo 1
often eavesdropped on critical
communication lines. Special equipment was developed for this purpose,
ranging from small portable devices, to multi-channel tapping and
recording systems.
