In the summer of 1430, 10,000 Hussites from Moravia invaded Hungary under Velek Koudelník of Březnice. The Hussites in Pozsony County looted and set on fire 100 villages. Against Koudelník stood an army under Sigismund, and Stibor of Stiboricz. The army included Hungarian and Transylvanian soldiers and Serbs. Another army under Jan Mátik of Tolovec was composed of Royalists. Mátik was jealous of Stiboricz, because of the trust placed in Stiboricz by Sigismund. At the front of the army, Stiboricz and the Hungarian-Serbian forces charged the Hussites, but Mátik and the Royalists deliberately hung back. The Royalists army belatedly arrived; the plan of campaign was a concentrated charge against the Hussite war-wagons. Koudelník was killed in the battle, and Sigismund's army was forced to flee
