In 1287, around 1400 Semigallians attacked a crusader stronghold in Ikšķile and plundered nearby lands. As they returned to Semigallia they were caught by the Order's forces, and the great battle began near the Garoza river (Battle of Garoza). The crusader forces were besieged and badly defeated. More than 40 knights were killed, including the master of the Livonian Order Willekin von Endorp, and an unknown number of crusader allies. It was the last Semigallian victory over the growing forces of the Livonian Order.
