• ADVANCE WARS 2 ROM CODEBREAKER CODES CODE

With the Japanese advance down the Malay Peninsula, the Army and RAF codebreakers went to the Wireless Experimental Centre in Delhi, India. Lieutenant- Commander Leo Brouwer RNN, a Japanese linguist at Kamer 14 was evacuated to Colombo, then Kilindini, and later Hut 7. Initially some of the FECB people went there after the fall of Singapore.

įECB also cooperated with Kamer 14 (Room 14), the Dutch unit at the Bandung Technical College in Java. But the Hollerith tabulating machine (minus a key part, which had to borrowed from the Indian State Railways in Bombay) arrived safely in Colombo. The ship's Master said he landed it at the Naval Store Singapore at the end of December 1941, but the Naval Stores Officer denied any knowledge of it hopefully it was destroyed or dumped in the sea. Supposed to be sent only by warship or military transport, it was trans-shipped at Durban to the freighter Sussex.

FECB was sent one of the American Purple machines from Bletchley Park in a warship. FECB also collaborated with the US Army Station 6 intercept site at Fort McKinley near Manila. There was interchange with Station CAST at Corregidor, which was better placed to intercept IJN messages, as FECB could only receive the Combined Fleet in home waters at night. The new codebook JN-25B was introduced on 1 December 1940, but was broken immediately as the additives were not changed. By May 1940 there were forty people working solely on JN-25, who could read simple messages. As Bletchley Park was concentrating on German Enigma cyphers, many of the Japanese naval section in Hut 7 moved to FECB, Singapore. An RAF "Y" interception unit, 52 Wireless Unit, arrived in Singapore in early November 1941. A skeleton staff of a codebreaker (Alf Bennett) and four intercept operators were left at Hong Kong, and they were captured by the Japanese on Christmas Day 1941.įECB went to Seletar Naval Base, and the intercept station to Kranji. In August 1939, shortly before the outbreak of war with Germany, the FECB moved to Singapore on HMS Birmingham for fear of Japanese attack. From 1936 many messages were sent back to London, to be deciphered by John Tiltman, who broke the first version of JN-25 in 1939. In 1938 a section was set up to attack Japanese commercial systems and so to track supply convoys.

Initially the Y section was to focus on the three main Japanese Navy codes and cyphers the Japanese Naval General Cypher, the Flag Officer code and the "tasogare" or basic naval reporting code used to report the sailings of individual ships. Colonel Valentine Burkhart found when he arrived in 1936 that the bureau was involved in “turf wars”, although they eventually accepted that they had no control over the use of intelligence reports. So by 1936 the two most senior naval officers were barely on speaking terms. Shaw had been dealing direct with GC&CS and the C-in-C Far East in Shanghai, but found that Waller expected that everything should go through him, and paid little regard to keeping sources secret. The FECB was headed by the Chief of Intelligence Staff (COIS) Captain John Waller, later by Captain F. The codebreaking or Y section had Japanese, Chinese and Russian interpreters, under RN Paymaster Arthur (Harry) Shaw, with Dick Thatcher and Neil Barnham. The intercept site was on Stonecutters Island, four miles across the harbour, and manned by a dozen RAF and RN ratings (plus later four Army signallers). The FECB was located in an office block in the Naval dockyard, with an armed guard at the door (which negated any attempt at secrecy).
