Dulles Knew

In an undated excerpt of a previously "confidential" paper(1) on the Central Intelligence Agency website it is clear that Office of Strategic Services(2) Bern(2a) Station Chief Allen Dulles was aware that the "Germans had broken many Allied codes" as early as the 19th of August, 1943(3). Previously to that, Dulles was informed by German Abwehr(4) source GISEVIUS(5) that "some Bern Legation messages had been read".

It is still not known precisely what codes were 'broken' or exactly when these codes were compromised, but US intelligence was indeed informed.

There are additional sources that indicate the Germans had broken (some) Allied codes prior to the raid on Ploesti(6).

Dulles along with an Gerald Mayer, a U.S. employee of the Office of War Information(3a) (Bern Station) met German citizen (soon to be US Spy) by the name of Fritz Kolbe at Mayer's Bern home on the morning of the 19th of August. It is at this meeting that Dulles (et al) was told about breaking of Allied codes. Koble, who would later be a valuable asset to the Allies, was employed in the German Foreign Office.
