I wondered whether you had read The Great Siege, Matla 1565 by Ernie Bradford. Having been beaten in Rhodes the Knights of St John base themselves in Malta. Which is then attacked in 1565 by the Sultan of Turkey with 40,000 men against six hundred Knights of St John and 9,000 men from Malta. It's a compelling read and a storyline crying out for further development. Mark French
I have the book, and have read it at least twice, and you're right - it's a magnificent tale and it is calling out for a novel - so who knows? I've had it in mind for years, but that doesn't mean I'll ever do it, alas.
