Notes

Prologue

1 Helen Kenny, Chooks at Chermside (A CB Mystery); Chermside & District Historical Society, Chooks and Tags.

2 Earlier histories of the code-breaking effort in the Pacific gave the credit to breaking JN-25 entirely to the United States Naval units at Hawaii and the Philippines, but it is now clear that the original break came from John Tiltman, and was delivered by Malcolm Barnett. Michael Smith makes this case in The Emperor’s Codes.

Chapter 1: The fires of a distant war

1 Spain and Portugal were also ruled by fascist governments, but they did not join the Axis alliance and remained neutral until the end of the war. Thanks to Peter Donovan for suggesting that I clarify this point.

Chapter 2: Tropical sickness

1 The Far East Combined Bureau, like the Middle East Combined Bureau, was controlled by the Government Code and Cypher School (GCCS), which for most of the war was based at Bletchley Park, England. The GCCS is often informally referred to as ‘Bletchley Park’.

2 Nave’s involvement in more traditional espionage activities including human intelligence in Hong Kong is clear from his memoirs, which are in the Australian War Memorial.

6 Nave left Singapore in February 1940, according to Peter Donovan and John Mack, Code Breaking in the Pacific, p. 72; see also David Jenkins, ‘Our War of Words’, Sydney Morning Herald, 18 September 1992.

Chapter 5: A wireless unit in Greece

1 Geoffrey Ballard, On Ultra Active Service: The Story of Australia’s Signals Intelligence Operations During World War II, p. 3.

2 Geoffrey Ballard, in On Ultra Active Service, refers to this as the British Air Ministry W/T Section in Heliopolis; Peter Donovan informs me that it was also the headquarters for Combined Bureau Middle East (CBME). The CBME would have been responsible for the training that Ballard and Inglis received.

2 Miriam Perlberg, Intelligence Lessons Learned from the Battle of Crete, 1941, Naval War College, Newport, RI. On page 4, Perlberg describes the dire situation that Freyberg found himself in, which I have described. Geoffrey Ballard, On Ultra Active Service had published his book in 1991, the year before Perlberg’s article, but the role of Australian signals on Crete, as elsewhere, was not well known among historians at the time.

Chapter 7: Mrs Mac and her girls in green

1 Newman’s visit occurred in late January 1941; the exact date is unknown. I’ve added some colour to this section by briefly describing the weather, based on Bureau of Meteorology historical data. There was only one day of heavy rainfall, 26 January, a Sunday. As Mrs Mac’s school did not run on Sundays, Newman did not visit in the rain. Late January was otherwise mild and sunny.

12 The seven RAAF personnel were Clarrie Hermes, S. ‘Snow’ Bradshaw, G. ‘Taffie’ Davis, Ted Cook, Alf Towers, B. ‘Bing’ Crosby, and J. Wilson. The Army personnel were Robert ‘Bob’ McGhie and one other individual, whose name has not been located. Snow Bradshaw was the NCO in charge of the unit when they went to Darwin. They would go to receivers installed at nearby Mont Park, tune it to the Japanese Navy HQ frequency and ‘pip’ it through to Victoria barracks, where the others could practise their interception skills. (Clarrie Hermes, ‘First and Last but Not Oldest’; and Jack Bleakley, The Eavesdroppers, p. 7).

9 There was also a third kind of code — Romaji codes — that spelled out words using Japanese representations of English letters. But Romaji codes were not used as a complete code system; they were typically incorporated into other codes and ciphers to represent placenames.

Chapter 17: Morse and Kana code

1 Bob Hartley, The History of the Australian Special Wireless Group, 1939 to 1947, p. 180.

2 Having the numbering of Army wireless sections start at 51 lessened confusion with other units, including the Four Special Wireless Section and the RAAF’s ‘wireless units’, which were numbered consecutively from 1 onwards.

7 The exact number of characters in the Kana code is difficult to ascertain. A copy of Keith Falconer’s Kana Code sheet, created in WWII, has 75 characters plus ten ‘short symbols’ for Universal Morse code numbers, making 85 characters. Geoffrey Ballard, On Ultra Active Service included two images of the Kana code; one has 69 characters and one has 72. The reason for the variations is not clear at present.

19 By coincidence, one of Bletchley Park’s celebrated code-breakers was also named William Clarke and also went by the nickname ‘Nobby’, a situation caused in part by the fact that, in those days, ‘Nobby’ was the default nickname for a man with the surname ‘Clarke’.

To add to the confusion, there was another William Clarke in Central Bureau, Squadron Leader W. J. Clarke, known as Bill. Bill Clarke established the Signals for Number 4 Fighter Sector in Port Moresby, and was commanding officer of signals at Milne Bay during the battle of Milne Bay, and received an MBE for his efforts. Bill Clarke’s obituary can be found in Central Bureau Newsletter, 2006, June, p. 7.

Stan Clark, in his Oral History, says that the Tulagi landings, in particular, being completely free of bloodshed were what earned him the MBE on the recommendation of Admiral Halsey — although, as Halsey took command in October, the most likely scenario is that either Vandergrift or Turner, or both, told Halsey about the high-quality intelligence they had been receiving.

7 Although it was not of interest to the traffic analysts, another feature of the preamble was of great interest to the code-breakers — the indicators. This was a key that gave the recipient specific information about how to unlock the message using the codebooks supplied. Once the operator had used a codebook to encode the message before sending, there would often be a second level of obfuscation using an additive book. The indicators told the recipient which section of the additive book, down to the page number, row and, column that the message had been encrypted with.

Although it is not certain, the person who processed the message at Townsville was probably Alan Marsland. See Helen Kenny, Vale Alan Marsland.

5 NAA: B5436, Central Bureau Technical Records — Part A Organisation, p. 10. Section 4, ‘Intelligence Production in the Field,’ states that field sections could bypass Central Bureau and pass important messages directly to the top of command. In addition, 1 Wireless Unit had a close working relationship with the United States Army signals corps stationed there, so that there was a direct channel to the American chain of command.

2 Sharon Maneki, The Quiet Heroes of the Southwest Pacific Theater, p. 29; Hyperwar, The Official History of the US Navy in World War II, Chapter VI, 1944. There has been some confusion about the identity of this ship, due to misspellings in various sources. The Central Bureau Technical Records misspell the name of the ship as the ‘Yoshino Maru’, which is the name of a different ship that was sunk near the Philippines later in the year. Sharon Maneki’s book, The Quiet Heroes of the Southwest Pacific Theater, also misspells it, using different spellings at different places in the book.
