 The late twelfth-century "Chronica naierensis" dates the encounter to 1070.Either in or as a result of the battle, Ramiro I of Aragon, one of the protagonists, died.Ramiro's first attempt to take Graus, the northernmost Muslim outpost in the valley of the Cinca, took place in 1055, probably in response to the defeat of García Sánchez III of Navarre at Atapuerca the year before (1054), which placed Ferdinand I of León and Castile in a commanding position against Ramiro's western border and the Muslim Taifa of Zaragoza to his south.
