The Secret Code Breakers of Central Bureau by David Dufty AA
Synopsis /
A groundbreaking work of Australian military history, The Code-Breakers of Central Bureau tells the story of the country’s significant code-breaking and signals-intelligence achievements during the Second World War. It reveals how Australians built a large and sophisticated intelligence network from scratch, how Australian code-breakers cracked Japanese army and air force codes, and how the code-breakers played a vital role in the battles of Midway, Milne Bay, the Coral Sea, Hollandia, and Leyte.
The book also reveals Australian involvement in the shooting down of Admiral Yamamoto near Bougainville in 1943, and how on 14 August 1945, following Japan’s offer of surrender, an Australian intelligence officer established the Allies’ first direct radio contact with Japan since the war had begun.
This is a rich historical account of a secret and little-understood side of the war, interwoven with lively personalities and personal stories. It is the story of Australia’s version of Bletchley Park, of talented and dedicated individuals who significantly influenced the course of the Pacific War.
My Thoughts /
This book tells the story of the emergence of signals intelligence in Australia during the Second World War, and of the men and women who worked for Central Bureau and other signals organisations based in Australia. The activities of those people remained secret for decades and were never recognised by the Australian government.
The Beginning.
The Second World War was a ‘global war’ that lasted from 1939 to 1945. It included all the great powers – forming two opposing military alliances – the Allies and the Axis – and directly involved more than 100 Million personnel from more than 30 countries. World War II was the deadliest conflict in human history, resulting in 70 to 85 million fatalities, with more civilians than military personnel killed. Tens of millions of people died due to genocides (including the Holocaust), premeditated death from starvation, massacres, and disease.
World War II is generally considered to have begun on 1 September 1939, with the invasion of Poland by Germany, under the leadership of Adolf Hitler and his Nazi Party (he invaded Poland with 1.5 Million troops). Hitler’s invasion of Poland in September 1939 drove Great Britain and France to declare war on Germany two days later.
The Book.
This is an intriguing, detailed look at the breaking of coded messages by the Australians and allies across World War 2. I found it to be a well thought out narrative into the expertise in the art of code breaking and admiration for the type of people recruited. A fascinating story of the Pacific War and finally, how the role of the code breaker expanded from the beginning of WW2.
Central Bureau. The Central Bureau was the (deliberately anonymous-sounding) name given to a large part of Australia’s WW2 code-breaking apparatus: yet as the war dragged on, the politicking and turf wars caused an enormous amount of fragmentation. Japanese Navy codes, Army codes, Water Transport codes, ground-to-air codes, sea-to-air codes: all of these were tackled and defeated. Yet even though the theoretical structure and nature of some of these codes were worked out early on, the codes themselves and the additive tables used to scramble them were subject to change. So the practical cryptologic work never ended until right up to the end of the War.
As the codebreaking process became more mechanised, and the volume of intercepts grew, many more staff were recruited from a wider range of sources. A significant proportion of these were recruited from the Women’s Services; the WRNS, the ATS and the WAAF. By 1945, 75% of the staff of Bletchley Park were women, and of these six out of ten were in uniform. The remainder were recruited through the Civil Service. As a consequence civilians and uniformed personnel worked alongside each other in most sections. 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.
Although quite dry for the most part, boredom is avoided by the often unusual or thought-provoking language; or, at the slight attempts at humour throughout. If you enjoy reading factual accounts or, love reading about history in general, you would find this book really enjoyable – so please add it to your TBR and let me know what you think.
Favourite Quotes.
1. What he did not grasp was that ‘solving’ a code and ‘breaking’ a code are two different things. The Allies had solved it, meaning that they knew how it worked – it used five numbers, an additive book that was applied in a certain way, and an indicator system. But they had not broken the code. Breaking a code involves learning enough code words and indicators so that any given message can be read.
2. Rudy Fabian had no desire to get involved in what he saw as ‘secret inks and all that crap’.
3. Lieutenant Alistair Wallace Sandford – None of his equipment was uniform. He deplored regimentation. He said he didn’t see why individuality should be suppressed, and made to conform to a common, very common, pattern. In short, he was somewhat out of place as an officer in the war-toughened Australian Signal Section. But as events were to prove, he was completely fearless and so in the end we accepted him as a brother in arms.
