One of George's schoolfriends has an Italian dad and they visit Italy several times a year. Last time they went I asked him to pick up these 2 books.
One on the battle of Anghiari by Massimo Predonzani who has written the recent Helion publications on the Italian Wars, and one about the Siege of Padua in 1509 called The Lion, the Eagle and the Cat (Venetian Lion, Imperial Eagle and the main defensive bastion of Padua was called The Bastion of the Cat).
Both in Italian which I can just about manage, using my O level Latin and Google translate. Full of fascinating details.
