The defeat, followed by the destruction of Veliuona and Pieštvė the following year, severely weakened Lithuanian defenses along the Neman River and opened central Lithuania to Teutonic attacks.
The Teutonic Order waged a decades-long crusade against the pagan Grand Duchy of Lithuania in attempts to conquer it and forcibly convert it to Christianity.
Lithuanian fortresses were wooden (Kolainiai, Veliuona, Pieštvė, Paštuva, Bisenė) until they began building stone and red brick Kaunas Castle near the confluence of the Neman and Neris Rivers.
[2] In 1361, the Order sent brother Henry of Schöningen on a reconnaissance mission to find out the size of the new castle so that an effective siege could be organized the next winter.
[3] To protect themselves from Lithuanian attack, the Teutons dug a canal connecting Neman and Neris, thus cutting off the castle from the mainland.
[3] Wigand of Marburg's Chronica nova Prutenica (New Prussian Chronicle) reports that the Teutonic army sang "Christ ist erstanden" after overcoming the pagan Lithuanian defenders.
[5] This severely weakened Lithuanian defenses along the Neman and started the most intense period of attacks towards central Lithuania, including Vilnius and Trakai.
