TheBattle of Ashmyany orAšmena (Lithuanian:Ašmenos mūšis) was fought on 8 December 1432 atAshmyany between the armies ofŠvitrigaila andSigismund Kęstutaitis, two pretenders to the throne of theGrand Duchy of Lithuania during theLithuanian Civil War (1432–1438).

Švitrigaila with several thousand troops (estimated to total about 40,000) marched out ofPolatsk, where he was staying, and tookMinsk,Kreva,Ashmyany, and was preparing to attackVilnius. Sigismund Kęstutaitis' Lithuanian andSamogitia army supported byMasurians fromDrahichyn (estimated to total about 20,000) attacked Švitrigaila's Lithuanian and Russian troops supported byTatars, led by KhanSayid Ahmad I. Švitrigaila'sLivonian Order allies did not arrive in time for the battle.

The battle lasted from morning until evening. At first, Sigismund's army was pushed by Švitrigaila's forces about 3 miles (4.8 km) towards Vilna, but Sigismund Kęstutaitis towards the evening beat and struck back at Švitrigailos forces. Both sides suffered heavy losses. According to the Polish chroniclerJan Długosz, about 10,000 of Švitrigaila's men were killed and 4,000 were captured. Švitrigaila escaped to Polatsk. The formervoivode of VilniusJonas Manvydas,Jurgis Lengvenaitis ruler ofMstsislaw, DukeJurgis Gedgaudas and other commanders of his army were taken into captivity.

Although Sigismund Kęstutaitis won the battle, his army was also weakened and so he could not pursue Švitrigaila and end the civil war. TheLithuanian Civil War (1431–1435) ended with the 1435Battle of Wilkomierz during which Švitrigaila's army was dealt a final defeat.^[1]
