Using psychology to find the wreck of the Sydney

The HMAS Sydney was a cruiser with an impressive battle record in World War II. But in November 1941 a German raider fired on the Sydney off the coast of Western Australia in the open ocean. She returned fire and both ships sank to the bottom. Three hundred Germans survived and were picked up by the Australian military. They were interrogated afterwards to try and pinpoint exactly where the ships went down. But no one beleived them until now.
