In a little celebration for good medical news, I bought two more medieval warfare/history books, this time with emphasis on religious war:
Victory in the East is the definitive military history of the First (and only really succesful) Middle East crusade, while Warrior of God is one of the few things in English about genius Hussite general Jan Zizka, who was so successful in battle larger Catholic armies avoided battle with the Hussites. And he was completely blind in several military campaigns!
May dig into these in my last vacation.
