Battle of Durbe

The Livonian Order had been fighting the Samogitians since 1253, when Mindaugas was crowned as King of Lithuania and transferred parts of Samogitia to the order. The Samogitians did not recognize the transfer and fought for their independence. For the knights, Samogitia was a strategically important region as it physically separated their Prussian and Livonian branches. After the Samogitians killed 12 knights in the Battle of Memel, near the newly built Memel Castle (Klaipėda) in 1257, a two-year truce was concluded. When the attack failed, they built a fortress in nearby Dobele (Doblen) and Georgenburg (possibly present-day Jurbarkas) in Samogitia. The Semigallians attacked Dobele, but, due to poor siege tactics, suffered heavy casualties. The Samogitians did not attack Georgenburg directly but built a fortress nearby, cutting off the castle from its supplies and continuously harassing the garrison. ==Battle==

Livonian grand master Burkhard von Hornhausen organized a large army for a campaign against the Samogitians. 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. When the armies of the Prussian and Livonian orders and their allies met in Memel Castle, they planned to reinforce the besieged Georgenburg. When the battle started, local Curonians abandoned the knights because the knights did not agree to free any captured Curonians from the Samogitian camp. Peter von Dusburg even alleged that the Curonians attacked the knights from the rear. The Estonians and other local people soon fled the battle. After this loss the knights were surrounded and suffered heavy losses. Some 150 knights perished along with hundreds of secular knights and low-ranking soldiers. Though the battle is described in the Livonian Rhymed Chronicle in detail, no contemporary sources mention who was the leader of the Samogitians. Only Simon Grunau, in his chronicle written ca. 1517–1526, mentioned that it was Treniota. In 1982, historian Edvardas Gudavičius published a study arguing that Treniota was not a Samogitian and could not have commanded a Samogitian army. Inga Baranauskienė argued that the battle was led by Alminas, a Samogitian elder elected before 1256. ==Aftermath==

Numerous rebellions against the Teutonic Order across all Baltic lands followed, including the Great Prussian Uprising, which lasted from 1260 to 1274. Zemgale rebelled for 30 years while Courland surrendered in 1267. These battles undid some 20 years of Livonian conquest and it took some thirty years for the Livonian Order to restore its control. 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. Treniota organized military campaigns into Livonia and earned support from the Lithuanians. In 1263, Treniota assassinated Mindaugas and usurped the Lithuanian throne, and the nation reverted to paganism. Ensuing instability prevented the Grand Duchy of Lithuania from taking full advantage of the weakened orders, however, while the orders were occupied reconquering rebelling territories and did not pose a danger to Lithuania until 1280–1285. In this sense, the battle bought time for the new Lithuanian state to mature, strengthen, and expand before facing a full-scale crusade. ==References==
