According to Ulrich Nieß, the destruction of the town was part of the order's policy of securing its lands from potential inner rivals. Nieß says that the destruction of the city walls was in line with the order's contemporary policy of not allowing their own foundations to be substantially fortified either, and that the refusal of the town to obey to the order's demand to level their walls led to a "policy of hardness" being implemented on the townspeople, who had to evacuate their houses which afterward were burned down. Nieß says that the procurator of the order had himself reported these proceedings to the pope, claiming the burghers evacuated and burned their houses voluntarily (which Nieß strongly denies). Nieß is also pointing out that in the subsequent capture of Tczew (Dirschau) by the order, the townspeople similarly had to sign an agreement to evacuate their homes, though this was not put into effect.
