Battle of Durbe

Some 150 knights were killed, including Livonian master Burkhard von Hornhausen and Prussian land marshal Heinrich Botel.

[2] The knights attempted to strengthen their strategic position and attacked Tērvete (Terwerten) hoping to turn the Semigallian outpost into a Teutonic castle.

[6] When the attack failed, they built a fortress in nearby Dobele (Doblen) and Georgenburg (possibly present-day Jurbarkas) in Samogitia.

The Samogitians did not attack Georgenburg directly but built a fortress nearby, cutting off the castle from its supplies and continuously harassing the garrison.

On 25 January 1260, the knights obtained a papal bull from Pope Alexander IV, blessing the crusade, and concluded a peace treaty with Siemowit I of Masovia.

[9] When the armies of the Prussian and Livonian orders and their allies met in Memel Castle, they planned to reinforce the besieged Georgenburg.

[5] In the aftermath of the defeat, Duke Treniota is alleged to have convinced his uncle Mindaugas, King of Lithuania, to deny his Christianity and break the peace with the Teutonic Order.

[14] In this sense, the battle bought time for the new Lithuanian state to mature, strengthen, and expand before facing a full-scale crusade.
