Update on OSS communications from Bern, Switzerland

After going through my files I’ve discovered more documents that have information on the compromise of OSS communications in WWII. Thus the following paragraphs are added in Allen Dulles and the compromise of OSS codes in WWII:

Report of Sturmbannführer Huegel

SS-Sturmbannführer Dr. Klaus Huegel was an important SD official with knowledge of German intelligence operations in Switzerland and Italy. In CSDIC/CMF/SD 20, he says that when he was working at the SD HQ he saw US intelligence reports from Bern:

A daily bulletin from the German High Command Cryptographic Service, OKW CHI, was sent to SS Brigadefuehrer SCHELLENBERG, the Head of Amt VI of the RSHA. It was signed by Generalmajor THIELE. From Apr 43 till Mar 44, source was in Amt VI, and often saw the bulletins. He remembers that the following links were intercepted and their traffic read, translations of matters of interest to Amt VI appearing in the bulletins:
USA Minister HARRISON in BERNE - WASHINGTON: Three or four signals daily, on the average, were intercepted. All traffic was read. This enabled Amt VI to judge the Swiss attitude to GERMANY as seen through American eyes, and also gave a good picture of conditions in GERMANY. Source says that Mr. HARRISON seemed to be particularly well-informed on the situation in MUNICH, for instance on the morale of the people and on rifts between various High Party officials, between GOERING and HIMMLER, RIBBENTROP and HIMMLER, etc. A conclusion drawn on several occasions in the messages was that though the population was restive, no organised underground resistance on a large scale was possible because of the power of the SS and Gestapo and other security bodies. Source says that Amt VI found these messages of great interest, and if any points raised required investigation, it was often found that the information had been correct.’

Under The Finnish connection:

David Kahn interviewed some of the Finnish codebreakers in the 1990’s (Aalto, Loimaranta, Pale) and they clearly remembered US telegrams containing intelligence reports and information on the German Resistance:

Q:  Why did you think the Americans used such weak codes?

A: They had no idea about that, the question was why the ambassador's telegram, everything in ….. cipher or ambassador send a list, a long, long telegram about conspiracy against Hitler with all the names. It was a very, very terrible business,

Another voice:  gave them away.

Q: Is that how they caught the conspirators.
