I think that the sailors amongst us will find this thread interesting.

There has been a Naval mystery from WW II that has had the experts stumped since 1941.

HMAS Sydney was patrolling in the Indian Ocean off the coast of Western Australia and disappeared without trace. It was later learned that she had encountered the German raider HSK Kormoran, a converted cargo ship. A battle ensued that put both ships on the bottom.

To cut a long story short, the search for the Sydney bore fruit a couple of weeks ago. The following link shows pictures of the remains of both ships and also tells a bit of the history of the Sydney.
