Abd al-Karim carried out a scorched earth campaign of aggression against the lands of Álava whilst his brother, Abd al-Malik directed his forces into the heart of the Asturian Kingdom without encountering significant resistance aside from the town of Oviedo. He destroyed much of the countryside, including churches built by Fruela I of Asturias. The battle resulted in an Asturian victory and the majority of the invading Muslim army was wiped out. Abd al-Malik was killed in the action.
