Despite Mindaugas's conversion, the Teutonic Knights regularly made incursions in Lithuanian territory. After the Battle of Durbe in 1260, Treniota convinced Mindaugas to relapse from Christianity and attack the Teutonic Order, though the attack was ineffective and the Teutonic Knights were barely weakened.
