ABSTRACT Konstantin Mihailović, a Serb born in Novo Brdo, was taken by the Ottomans and became a janissary in Mehmet II’s army. After he returned to the Christian side, he penned a report on Ottoman governance, religion, military structures and tactics. It explained by organisational advantages, fairness to subjects of all faiths coupled with deceit vis-à-vis enemies, divisions within Christendom, and providential history’s retributive measures, why the ‘heathen’ had the upper hand. But the author, Konstantin, remained discreet. Autobiographical details on his years as a janissary are scarce. He had risen high in the Ottoman system. While conveying his expertise about the enemy to Christian courts was his key to a further career, he also had to conceal that he had been an important member of the janissary corps, and probably had converted to Islam. The first imperative, sharing expertise, complicated the second, self-silencing, and made it impossible to dissimulate fully.

叛变者之一：塞尔维亚卫兵康斯坦丁·米海洛维奇（KonstantinMihailović）和奥斯曼帝国征服巴尔干半岛

摘要康斯坦丁·米哈伊洛维奇（KonstantinMihailović）是诺沃·布多（Novo Brdo）出生的塞尔维亚人，被奥斯曼帝国所占领，并成为穆罕默德二世军队的门卫。回到基督教方面之后，他撰写了一份有关奥斯曼帝国的统治，宗教，军事结构和战术的报告。它以组织上的优势，对所有信仰主题的公平以及对敌人的欺骗，基督教世界内部的分裂以及天国历史的报应手段来解释，为什么“异教徒”占了上风。但是作者康斯坦丁仍然保持谨慎。关于他一周年的自传的详细资料很少。他在奥斯曼帝国的制度中地位很高。向基督教法庭传达有关敌人的专业知识是他进一步职业的关键，但他还不得不隐瞒自己曾经是看门军的重要成员，并且可能已经converted依了伊斯兰教。
