With the help of military units from the Kingdom of Poland, the forces of Grand Duke Sigismund Kęstutaitis soundly defeated Švitrigaila and his Livonian allies.

Švitrigaila lost most of his supporters and withdrew to southern Grand Duchy; he was slowly pushed out and eventually made peace.

It came into use as a name for the town of Pabaiskas which grew around the Church of the Holy Trinity built at the site in 1436–40 by Sigismund Kęstutaitis.

The Lithuanian nobles elected Švitrigaila, Jogaila's brother and Vytautas' cousin, as the new Grand Duke without first consulting with Poland.

Švitrigaila escaped, established himself in Polotsk, and rallied his supporters from Slavic lands of the Grand Duchy against Sigismund.

[6] In 1433, together with the Livonian knights, Švitrigaila raided Lida, Kreva, Eišiškės and devastated the surrounding areas near Vilnius, Trakai, and Kaunas.

After two days, Švitrigaila and Livonian Grand Master Franco Kerskorff decided to change their position and move north towards Vilkmergė.

Švitrigaila's army was split in half; the first to fall was the flag of Livonian marshal Werner von Nesselrode.

[8] Many others, including Duke Yaroslav, son of Lengvenis, and imperial envoy Sigismund de Rota, were killed.

[2] That provision was meant particularly against Sigismund, Holy Roman Emperor, and his attempts in playing Poland and Teutonic Order against each other.

[1] Švitrigaila escaped and continued to resist, but he was losing his power in the eastern provinces of the Grand Duchy of Lithuania.

In 1437, he proposed a compromise to continue to rule Kiev and Volhynia, territories that still remained loyal to him, until his death, when they would pass to the King of Poland.
