Strategic Narrative Overview

The Teutonic Order besieged Kaunas Castle for approximately one month. Despite its newly constructed defenses, the castle fell to the attackers. The Lithuanian commander Vaidotas, a son of the prominent duke Kęstutis, along with 36 others were taken captive. The Teutonic Knights then destroyed the castle, eliminating it as a defensive asset on the Neman River line.

01 / The Origins

In the mid-14th century, the Teutonic Order conducted sustained military pressure against the Grand Duchy of Lithuania along the Neman River frontier. Lithuania constructed Kaunas Castle as its first brick fortification to resist these incursions. The Teutonic Knights, seeking to eliminate Lithuanian defensive positions and expand their reach into the region, laid siege to the newly built castle in spring 1362.

03 / The Outcome

Following the fall of Kaunas Castle, the Teutonic Order pressed its advantage the following year by destroying the Lithuanian fortifications at Veliuona and Pieštvė. These successive losses severely weakened Lithuanian defensive capacity along the Neman River, leaving central Lithuania exposed to continued Teutonic raids and military incursions for years afterward.
