January/February 1943.

German B-Dienst (a/k/a German B-Service) succeeded in breaking enemy (British) ciphers. German Admiral Doenitz received British U-boat Situation Reports (Jan/Feb 1943).

Early 1943 (before March 13th). Former member of German Abwehr and now employee of German Legation/Consulate in Zurich (Hans Bernd Gisevius) volunteers information to OSS Bern Station Chief Allen W. Dulles that German B-Dient Group has broken US Legation code system. Gisevius provides evidence to Dulles that the OSS/Bern OSS/Washington OSS/London code has been compromised.

March 43

In March (16th) two British convoys (HX-229 and SC 122) were destroyed by German U-boats. These disasterous losses are attributed to broken British codes by the Germans in Paul Manning's "Martin Bormann: Nazi in Exile", page 108.
(Elements of 506th BS, 44th BG, 2nd AD were being transported from ZOI/CONUS to ETO/UK on TSS Chantilly which saled as part of SC-122.)

According to webpublished database "Ahoy - Mac's Web Log" (Mackenzie J. Gregory) "
Allied intelligence on the 12th. of March read a message from U-621, indicating he had sunk a straggler from Outward Bound North ( slow ) 169, the Baron Kinnard, SC122, was ordered to alter course southward to slip past the waiting Raubgraf wolf pack. This was successful, but the two other groups still lay in the path of SC122, with Sturmer with 18 boats, and south
of them Dranger, with their 11 boats. Danger was in the offing!

Intelligence blackout from 10th. to 19th. of March 1943. But because of the loss of Naval Enigma over the time frame of 10th. to 19th. of March in 1943, Allied Control was unaware of the other two wolf packs lying in wait for SC122."

"The 10 days when the Code breakers were bereft of the U-Boat signal traffic had proved very costly, 22 ships sunk, crewmen dying, and their precious cargoes destroyed. By the 20th. of March 1943, all the U-Boat traffic was again being read."

In National Archives Prologue Magazine Spring 2002, Vol. 34, No. 1, A Time to Act: The Beginning of the Fritz Kolbe Story, 1900 - 1943, Part 4 , By Greg Bradsher, Dulles and Kolbe meeting it is revealed that a meeting of Dulles and Fritz Kolbe took place. Bradsher says "He also discussed the fact that German cryptanalysts had broken many Allied codes and cited from
memory the substance of an OWI cable."

Bradsher relates another meeting with Kolbe and Mayer (an OSS associate) on August 19th (1943), presumably in Berne, Switzerland. " Kocherthaler and Kolbe showed up at Mayer's apartment on Thursday, August 19, at 10:30 A.M., where they remained until approximately 2.30 P.M.115 There appears to be no record of what took place. Later that day both Mayer and Dulles wrote up their recollections of the meeting while it was still fresh in their
minds.116 " Another meeting occurs on August 20th.

(According to Page 1 (also page 69) of previously Confidential document approved for release, CIA Historical Review Program, 22 September 1993 titled "Alias George Wood" by Anthony Quibble Fritz Kolbe first met Allen Dulles' associates on Tuesday, 17 August 1943.

The first meeting appears to have occurred on the evening of August 18th or early morning of the 19th of August, 1943.

Another Koble meeting took place in the morning of 20th August. Bradsher reports "Kolbe again warned that the Foreign Office constantly received deciphered code messages of American as well as British warships at sea and also messages originating in the Cairo and Moscow legations and consulates of the Allied nations."

The B-Dienst (Beobachtungsdienst) was a German Naval codebreaking organisation. During World War II, B-Dienst solved British Naval Cypher No. 3, providing intelligence for the Battle of the Atlantic, until the British Admiralty introduced Naval Cypher No. 5 on 10 June 1943. B-Dienst also solved a number of merchant codes.
