In Batavia, Governor General, Jan Coen, gave Pelsaert command of the rescue mission, which arrived at the islands two months after leaving Batavia, to find the survivors greatly diminished by mutiny, murder and general mayhem, a strange and terrible saga that has provided material for a number of historical accounts.
Cornelisz, left in charge of the survivors, planned to hijack the rescue vessel to seek another safe haven but needed to eliminate possible opponents. He started by sending a group of soldiers to nearby islands to search for water. 
With one group of rivals gone, Cornelisz and his allies set about killing anyone who threatened their ambitions, planning to reduce the population to around 45 to ensure that their supplies would last as long as possible. In the process at least 110 men, women, and children were murdered.
Pelsaert's return produced a brief struggle before the mutineers were captured, tried and executed. Of the 341 people aboard Batavia, only 68 made it to Java.
Containing material that has salvaged from the wreck, the Shipwreck Gallery is the sort of place you could comfortably lose a couple of hours exploring, but Madam wanted to catch The Roundhouse, the original jail for the Swan River Colony’s port, and Hughesy had ambitions of checking out the Maritime Museum, though that’s not quite the way things worked out.
The visit to The Roundhouse provided the odd interesting photo opportunity, and time was getting on. Doing the Museum thing takes a bit out of you, and by the time we'd reached the actual Maritime Museum, there wasn't much time left to check out the displays.
Madam wasn't over-keen, I was tired, and the $10 admission fee didn't seem to be a justifiable expenditure when there wasn’t anything among the exhibits the guy in the ticket booth rattled off that jumped out and demanded my immediate attention.
Having decided that was a non-goer, we were on our way to the nearest bus stop when the Fremantle CAT whizzed past, and were too tired to make the sprint to catch it when it pulled up about seventy metres away. There'd be another one in ten or fifteen minutes anyway.
