"most constantly profitable sources" of intelligence on German plans and
movements.
Strategic communications intelligence about German in-

sources. This should not be surprising. The Wehrmacht had the
advantage of interior communications throughout occupied Europe and
so could use wire networks, which offer very little opportunity for
interception. But the Japanese diplomats in Berlin, Rome, Madrid,
Lisbon, Sofia, Budapest, and Moscow had no way of getting messages
back to Tokyo but by radio. These the Allies intercepted.
