Sydney, Cipher and Search: Solving the Last Great Naval Mystery of the Second World War by Captain Peter Hore

Sydney, Cipher and Search: Solving the Last Great Naval Mystery of the Second World War, by Captain Peter Hore, (Naval Institute Press: 2009), 320 pages.

Captain Peter Hore has written, arguably, the definitive book on the “mystery” of the sinking of the Australian cruiser H.M.A.S. Sydney by the German raider Kormoran in November 1941 with the loss of all 645 hands. It has long been acknowledged that the Australian light cruiser H.M.A.S. Sydney was sunk by the German raider Kormoran off the coast of Western Australia. Survivors of the Kormoran (disabled in battle and subsequently scuttled) captured and interred in Australia reported individually to investigators that they engaged H.M.A.S. Sydney at a range of about half a mile, causing great destruction that eventually caused her to sink. The “mystery” referred to in the title is how the Kormoran, a converted freighter with guns and torpedo armaments equivalent to that of a cruiser, could cause the loss of the pride of the Australian navy with the loss of its entire crew. To his credit, Captain Hore presents all of the facts from primary sources, including some that he discovered, to explain what happened. Captain Hore's sources include re-constructed and newly translated (by the author) battle logs written in code in a German-English dictionary by the Kormoran’s captain; Australian, German and British naval archive material; the author's interviews of surviving Kormoran crew members in Germany and Chile; and photographic evidence of the wreck of H.M.A.S. Sydney, located for the first time in 2008.

Captain Hore’s book is neither emotional, nor accusatory; he neither evangelizes his reader to a particular explanation or theory, nor attributes either praise or blame to the crews of H.M.A.S. Sydney nor the Kormoran. Rather, he simply collects evidence from all sources to explain what happened and lets the facts speak for themselves. The facts are that H.M.A.S. Sydney failed to follow established naval wartime procedures for identifying suspicious freighters, and brought herself broadside to the Kormoran at a range of approximately half a mile. When H.M.A.S. Sydney (which was not at battle stations) challenged the Kormoran, the captain of the Kormoran removed her disguise, ran up her German flag and commenced firing on H.M.A.S. Sydney with all of her guns and torpedoes causing catastrophic damage that caused her loss, and the loss of all crew. H.M.A.S. Sydney’s counter fire disabled Kormoran, which her crew subsequently abandoned and scuttled. These facts were found to be consistent with photographs of the wreck of H.M.A.S. Sydney. Captain Hore’s book presents all of the known facts, which leaves this reader with the opinion that the Kormoran should be solemnly recognized as having achieved something quite extra-ordinary: this was a major success for the Kormoran – something never before achieved where a raider (a converted freighter with significant weaponry) sank a cruiser with the loss of all hands. Conversely, for H.M.A.S. Sydney, it was a complete and total disaster. What is not known, nor will ever likely to be known, is why H.M.A.S. Sydney’s captain disregarded established wartime naval procedures and placed his ship and the lives of all of the crew in such a vulnerable position.

Captain Hore has written a fine book that explains all of the facts on the loss of H.M.A.S. Sydney. The book reads like a novel: it is interesting and fast-paced mixing discovery, de-ciphering and code breaking, travel, and first person interviews on multiple continents. The final product is an excellent story accessible to both experienced armchair naval experts interested in relatively obscure naval battles, and civilians who simply enjoy a good story well written. At the same time, this book could rightly be considered the definitive or authoritative book on this subject, which in itself is quite an achievement.
