Jan Žižka enters our historical awareness only at the beginning of the Hussite storms. But what did he do before that? Where did he gather his warrior experience? In 1410, one of the greatest battles of the Middle Ages took place - the Battle of Grunwald. Historians are not sure about the participation of the Hussite warlord, but they claim that he was certainly in Poland at that time, which is also supported by written evidence. However, it is not certain that he actually fought in it himself. However, there are written reports that he not only participated in the fight, but also intervened in it in a significant way. Although it is fiction, each chapter is accompanied by factual notes from which the author was based.
