Čeněk von Wartenberg

From Wikipedia:

Čeněk of Wartenberg (Czech: Čeněk z Vartemberka; German: Vinzenz von Wartenberg; c. 1379 – 17 September 1425)[1] was a commander of the Royalist Bohemian forces at the start of the Hussite Wars.[2] Up until the first half of 1420 he was a commander of the Utraquist League, a moderate fraction of the Hussite movement. As a result of severe atrocities committed by Taborites,[3] members of the more radical part of this movement, he returned to the royalist/Catholic side.
