mean that it was Gediminas who was killed, but modern historians Edvardas Gudavičius and Alvydas Nikžentaitis argue that it was a son of Gediminas. After successfully withstanding the siege, Bayernburg was awarded weapons, food, flag and coat of arms by Duke Henry XIV. On 15 November 1337, Louis IV, Holy Roman Emperor, gifted to-be-conquered Lithuania to the Teutonic Order and named Bayernburg as the capital of the to-be-conquered land and future diocese. Duke Henry XIV, in turn, promised to built the cathedral. Since the pope decided diocesan affairs, the emperor reissued his privilege on 12 December emitting any references to the diocese. Second Bayernburg (1344–84) In 1344, after deliberations with his officers, Grand Master Ludolf König decided to abandon the first Bayernburg. The fortress was burned down and the second Bayernburg was built about one mile down the Neman River. The reasons for this relocation is not known. Perhaps the first fortress was too far into the Lithuanian frontier and was difficult to supply and maintain. The second Bayernburg stood on the Lithuanian frontier for a few decades and was a base for further Teutonic raids into Lithuania. For example, in 1369, Teutonic soldiers took a supply of food for their campaign to reinforce Gotteswerder. Repeating this information German historian Caspar Schütz made an error by claiming that the fortress, known as Beyery, was controlled by Kęstutis. This confused note led some Lithuanian researchers to look for a Lithuanian fortress, known as Bairiai. Algirdas Makarevičius "found" it near the Nevėžis River north of Raudondvaris. In 1381, Lithuanians commanded by Kaributas, brother of Grand Duke Jogaila, attacked Bayernburg when they learned that it was defended only by a handful of soldiers. The Teutons decided to defend the fortress. Seeing that they were unable to defend the outer bailey, they burned it down themselves. After six days, the Lithuanians retreated as Bayernburg was about to receive reinforcements from Ragnit. The fortress was captured and burned down in July 1384 by Vytautas when he reconciled with his cousin Jogaila at the conclusion of the Lithuanian Civil War (1381–84). Vytautas also burned down Georgenburg and New Marienburg. Third Bayernburg (1387–1403) The third Bayernburg was built in spring 1387 where Georgenburg stood. The new name did not gain popularity or acceptance and the fortress continued to be known as Georgenburg. This fortress was captured and burned down by Grand Duke Vytautas in April 1403 during
