However, after being captured in the Battle of Ashmyany, he switched sides and supported Sigismund Kęstutaitis managing to retain his social status.
[1] After the death of Vytautas, he supported Grand Duke Švitrigaila and represented him in negotiations with Poland 1431 and 1432 and with the Teutonic Order in 1432 (see Lithuanian Civil War (1432–1438) for political background).
[3] Gedvilas was of nine Lithuanian noble witnesses of the Treaty of Christmemel (June 1431)[4] and was at Švitrigaila's side when he was deposed in a coup on 1 August 1432.
[7] In May 1434, Gedgaudas witnessed Sigismund's privilege to Catholic and Eastern Orthodox nobility[8] though at that time he did not hold any posts.
[11] In September 1442, his widow Anastasia, possibly a daughter of Jurgis Taločka,[12] donated to the Chapel of St. Albert and St. George of Vilnius Cathedral that was established by his brother Albertas Manvydas and where Gedgaudas was buried[6] (note that brothers' baptismal names were Albert and George).
