The Battle of Krbava (1943.), in which the Croatian army led by the ban Emerik Derenčin had suffered a crushing defeat by the Ottomans, has been preserved in older historical sources, such as in the report of the papal envoy Antonio Fabregues (1493.), in the Record of Father Martinec in Novljanski brevijar from 1493. or in the description written by the Bishop of Nin Juraj Divnić (1493). In addition to these inscriptions, an important source for better knowledge of the details of the Battle of Krbava is certainly the work Commentarii de temporibus suis by Ludovik Crijević Tuberon (1458 - 1527). The work contains information about significant participants in the battle and their fates, the location of the battle and the conflict between ban Derenčin and Croatian nobles regarding the location of the battle. In addition, Tuberon cites greed of Croatian nobles and a longing for fame by the ban as the main cause of defeat. After a brief overview of the socio-political circumstances of those years, this paper presents Tuberon's description of the Battle of Krbava, and emphasizes similarities and differences of Tuberon's description of the battle with those of Bishop Juraj Divnić or friar Ivan Tomašić.
