From Schadewitz´s "The Meuse First and then Antwerp"


On 4th September 1944 the Japanese Ambassador Baron Oshima attended a meeting with Hitler. Hitler told that he was about to start a large-scale offensive in the west after the beginning of November.

A few days later Oshima reported to Tokyo, which was intercepted and decrypted by "MAGIC". The information was passed on to the intelligence officers in Pentagon.



Here might be more interesting messages sent by Oshima and decrypted by the US intelligence:
