Bolesław Krzywousty's group of warriors - a wooden settlement surrounded by an earthen embankment with a wooden palisade. It is located on an island in the middle of the river. The defenders and inhabitants of the town are fighting on the rampart. They throw boulders and pour boiling water on the attacking warriors. The warriors climb the embankment using ladders. They are trying to break down the castle gate with a battering ram made of a log.
