There is much more context about the Ottoman Empire, corsairs, and siege warfare in general than actual information about the Great Siege itself in The Great Siege of Malta, but it turns out that I am much more interested in the wider historical picture than the difficult-to-follow machinations of specific battles, so I didn't mind. I did go in hoping for information about life on Malta for the Maltese in this period, but unfortunately the aristocratic Knights of St John didn't much care about the locals and only seem to record their existence when it’s related to crime and/or prostitutes, so you have to make to with glimpses and extrapolation.
Overall, interesting but not fascinating, and seemed to give a balanced view of both sides of the conflict.
