The crusade was called because the Pope believed that the Hussite armies would be easily defeated after the death of Jan Žižka.
Medieval chronicles states that Hussites had 24,000 soldiers and at least 500 war wagons, while the crusaders had 36,000 men.
The Hussite cavalry inside the Wagenburg had left and attacked the knights trying to breach the wagon chains from the rear.
The knights were then surrounded and fell under a huge barrage of artillery, crossbow, and handgun fire.
The actual battle was brief, and for that reason, it is possible that no more than 4,000 soldiers were lost on the crusader side.
