The Pechenegs crossed the Gate of Meses and plundered the Nyírség region, reaching as far as the fortress at Bihar. After plundering much booty, they returned to Transylvania along the valley of the River Someș, planning to return to their homeland through the Borgó Pass (the Tihuța Pass, now in Romania). King Solomon and his cousins, Dukes Géza and Ladislaus, gathered their troops at the fortress of Doboka to give battle to the marauders near the confluence of the Rivers Beszterce and Sajó (now the Bistrița and the Șieu, respectively). A scout from Marosújvár (now Ocna Mureș in Romania) informed the Hungarian army of the movements of the enemy. In an attempt to avoid the battle, the Pechenegs fled to a hill where the Hungarians annihilated them. The hill was named for the Hungarians' battle cry - Kyrie eleis, according to Bóna. The alternative name of the battle (Battle of Cserhalom) derives from the misspelling of the name by Antonio Bonfini, who wrote of Cherhelem instead of Kyrie eleis.
