HMAS Sydney was the pride of the fleet during the Second World War. A light cruiser and one of Australia's main combat vessels.

On the 19th November 1941, off the coast of Western Australia, The Sydney engaged in a fierce and bloody battle with the German raider Kormoran.

Following this action, The Sydney failed to return to port.

An extensive search and rescue carried out, but the warship had disappeared with all 645 men on board. Whilst the battle lasted little more than an hour, this single ship engagement remains Australia's greatest naval disaster.

More Australian servicemen died in the battle between the German raider Kormoran and the light cruiser HMAS Sydney than perished in the Vietnam War.

It was not until 2008 that the wreck was discovered. The passage of time between the sinking and the discovery led to numerous mystery and conspiracy theories, all of which started replacing the truth. Now, with an explanation of how those on board lived, fought, and died, this book tells the full story.
