Новгородская первая летопись
On July 24, 1343, the Oeselians arose yet again, killing all the Germans on the island, drowning all the clerics, and besieging the Livonian Order's castle at Pöide. After the garrison surrendered the Oeselians massacred the defenders and destroyed the castle. In February 1344 led a campaign over the frozen sea to Saaremaa. The Oeselians' stronghold was conquered and their leader Vesse was hanged. In the early spring of 1345, the next campaign of the Livonian Order ended with a treaty mentioned in the Chronicle of Hermann von Wartberge and the Novgorod First Chronicle.
