The Battle of Krücken was a medieval battle fought in 1249 during the Prussian Crusades between the Teutonic Knights and Prussians, one of the Baltic tribes. In terms of knights killed, it was the fourth largest defeat of the Teutonic Knights in the 13th century.Marshal Heinrich Botel gathered men from Kulm, Elbing, and Balga for an expeditionary attack deeper into Prussia. They traveled into the lands of Natangians and pillaged the region. On their way back they were in turn attacked by an army of Natangians. The Knights retreated to the nearby village of Krücken south of Kreuzburg (now Kamenka south of Slavskoye), where Prussians hesitated to attack. The Prussian army was growing as fresh troops arrived from more distant territories, and the Knights did not have enough supplies to withstand a siege. Therefore, the Teutonic Knights bargained for surrender: the marshal and three other knights were to remain as hostages while the others were to lay down their weapons. The Natangians broke the agreement and massacred 54 knights and a number of their followers. Some knights were executed in religious ceremonies or tortured to death. The severed head of Johann, vice-komtur of Balga, was mockingly displayed on a spear.
