In 1068, the invaders broke into Transylvania through the passes of the Carpathian Mountains. Archaeological finds suggest that they destroyed at least three fortresses made of earth and timber, including the ones at Doboka (now Dăbâca in Romania) and Sajósárvár (present-day Șirioara). They also made a plundering raid in the Nyírség region, to the west of Transylvania. After taking much booty, they planned to leave Hungary, but the Hungarians ambushed and annihilated them at a hill near Doboka. According to a popular legend, a Cuman warrior tried to escape from the battlefield, taking a Hungarian girl, but Duke Ladislaus defeated and killed him in single combat.
