[4] In 1347, the Teutonic Knights saw an influx of crusaders from France and England, where a truce was made during the Hundred Years' War.

[1] Their expedition started in late January 1348, but due to bad weather, the bulk of the forces did not proceed further than Insterburg.

The Lithuanians, led by Kęstutis or Narimantas, also had short supplies and decided to attack by hurling arrows and spears injuring a great number.

[3] As a result of the defeat Lithuanians were weakened: the same year the Knights attacked and pillaged Šiauliai area without much of opposition and destroyed a castle in Veliuona.

[6] The Knights attributed the victory to the Virgin Mary and in her honor Grand Master Winrich von Kniprode established a Cistercian nunnery in Königsberg[2] and a Franciscan monastery in Wehlau.
