The Secret Code-Breakers of Central Bureau: how Australia’s signals-intelligence network helped win the Pacific War Reviews

    There are few resources on General MacArthur 's Central Bureau, let alone from the Australian perspective.

    David Duffy fills this niche well

    He has several wonderful moments in the narrative dealing with the Australian women as Morse code operators including one between the Australian military chiefs and the Prime Minister calling them out on their sexism over theirs antics in trying to avoid using them.

    The Australian role in the breaking the coded message leading to the shoot down of Adm. Yamamoto is also detailed including the fact the Central Bureau provided a complete decoded version of the message in a lessor air to ground code message that was used to by U.S. Navy code breakers to crack the version in the stronger JN-25 Japanese Naval code.

    All in all it rates a strong five stars.

    This was a fascinating story of signals intelligence officers from Australia and USA mainly in Melbourne and Brisbane and Irian Jaya and Philippines and Japan. I enjoyed the code-breaking techniques and decrypting of Kana Morse Code to interpret Japanese military messages that caused World War II to end sooner. This is a remarkable and well kept secret story. I am glad I read it. It inspired me. It has a very extensive bibliography and both name and subject index so well written and researched.

    This book is an awesome read. I’d recommend it even to those who wouldn’t normally read non-fiction. At first, I feared that it would be rather dry, but it is told in such a way that it is enthralling. This part of Australia’s history should be taught in schools. I was fascinated, in fact, shocked, at the scale of the role Australian code breakers played in WWII. I had no idea how close Australia came to having a war on the continent. And no idea that female codebreakers played such a role. Thei

    This book is an awesome read. I’d recommend it even to those who wouldn’t normally read non-fiction. At first, I feared that it would be rather dry, but it is told in such a way that it is enthralling. This part of Australia’s history should be taught in schools. I was fascinated, in fact, shocked, at the scale of the role Australian code breakers played in WWII. I had no idea how close Australia came to having a war on the continent. And no idea that female codebreakers played such a role. Their treatment was sexist and appalling and they deserve far more recognition than they have received. In fact, I’d like to see a movie made about them. I was not, however, shock at the first-class political bullshit that went on. It is disgraceful that those operatives were denied medals when they were identified as deserving them due to politics. Those involved should hang their heads in shame. I very good book.

    This book reveals in detail the amazing people made up of mathematicians, code-breakers and radio experts who intercepted the Japanese Imperial Armed Forces attack plans making it possible for American and Australian Armed Forces to thwart many of these planned operations. General Douglas MacArthur was so impressed with their work that the men of Central Bureau accompanied him on his counter-attack in the Pacific.

    This book reveals in detail the amazing people made up of mathematicians, code-breakers and radio experts who intercepted the Japanese Imperial Armed Forces attack plans making it possible for American and Australian Armed Forces to thwart many of these planned operations. General Douglas MacArthur was so impressed with their work that the men of Central Bureau accompanied him on his counter-attack in the Pacific.

    The Kana code was the Japanese version of Morse from the Japanese orthographic Katakana, 75 separate characters. Learning the actual Katakana symbols was not possible due to the urgency of time and lack of language skills of the Australians. Those training to learn the dit dit dot of Morse had to learn extra symbols via the Latin alphabet that would cover for the extra Japanese symbols.

    All those involved were sworn to secrecy and many died without revealing anything to anyone. Sadly the Australian Government made the Australian Code Breakers wait until 2011 for acknowledgement of their service and even then it came from Britain. The US army wanted to award 3 men with the Medal of Freedom with a Bronze Palm for their services in WW2 however the Australian bureaucrats could not agree to the awarding of medals by a foreign power.

    Another obstacle during this time was the shortage of labour. Women were recruited for the first time into the Armed Forces with great awkwardness due to the lack of female facilities etc. In typical male prejudice attitude of the times females were not allowed to be posted overseas.
