Battle of Aizkraukle

The Battle of Aizkraukle or Ascheraden was a battle fought on March 5, 1279 between the Grand Duchy of Lithuania, led by Traidenis, and the Livonian branch of the Teutonic Order near Aizkraukle (German: Ascheraden) in present-day Latvia. The Order suffered a great defeat: 71 knights, including the Grand Master Ernst von Rassburg, and Eilart Hoberg, leader of the knights from Danish Estonia, were killed. It was the second-largest defeat of the Order in the 13th century. After this battle Duke Nameisis of the Semigallians recognized Traidenis as his suzerain.
