In November 1941, two ships crossed paths off the coast of Australia. One was the German raider HSK Kormoran. The other: an Australian warship called the HMAS Sydney. Guns were fired, the ships were damaged, and both sank to the bottom of the ocean.
The loss of the Sydney in World War II was a national tragedy for the Australians, particularly because none of the 645 men onboard survived. In the years that followed, there was intense interest in finding the wrecks, particularly the wreck of the Sydney. The idea was that doing this might give the families of the lost sailors some measure of peace, a sense of closure and certainty.
The problem was that the only witnesses to the battle and the sinking were about 300 German sailors who had abandoned their ship after it had been hit.
