This isn't ancient history, but who cares? I love maritime archaeology and the story of the Batavia shipwreck, mutiny and massacre is dramatic and bloody.
"On the morning of the fourth of June 1629, the Batavia was wrecked on Morning Reef, on the Houtman Abrolhos (Lat. 28º 29.422S, Long. 113 º 47.603E), off the coast of Western Australia. She was the first of the Dutch ships lost off the west coast of Australia. The shipwreck was a prelude to an extraordinary tragedy." Source: Western Australian Museum.
I'm not even going to try to summarize what happened next, but this is one of the craziest and most brutal sea stories I've ever run across. Highly recommended.
