Sample text

In 1935 the apartment of the Japanese naval attaché in Washington was burglarized, though nothing of value was found. Later, in May 1941, in one of the most brazen efforts, a team of navy and customs personnel boarded the Japanese merchant ship Nichi Shin Maru of the Pacific Whaling Steamship Company at Port Costa near San Francisco. They planted some drugs in the captain’s cabin and in the ensuing confusion confiscated his copy of the current merchant (Maru) code and several other documents dealing with communications.

It was not until around 1932 that the SIS began to attack foreign codes and ciphers. Even at that, the SIS was limited at what systems to try to solve, mainly diplomatic traffic. The major problem was that the Army still lacked a substantial intercept element to collect the messages. An early provisional unit at Fort Monmouth, New Jersey, began to monitor and copy some diplomatic and commercial messages in the mid-1930s, and these, by default, became the main target of SIS cryptanalysts. Early successes followed against Japanese manual systems like the early syllabary codes.

At the same time, independently of the Americans, the British and Dutch codebreakers in Singapore and Bandung were also exploiting the new manual system and its successors. By August 1941 the Gaimusho cryptographers were ready to activate the latest variant. Rowlett and his team were tipped to the new system by a message from Tokyo to Washington on 22 June 1941. 21 The first two messages in the new FUJI system were discovered to have been literally double superenciphered with the Purple machine.
