 The "Chronicle of Alfonso III" records that Musa directed his forces against the "Franks and Gauls", killing many and razing many places.The Gascon presence at Albelda in 851 may be explained as an attempted reprisal for an attack by Musa north of the Pyrenees, since at that time Musa was allied with the Kingdom of Pamplona, Gascony's southern neighbour.In 851, the year after he succeeded to the throne, Ordoño I of Asturias suppressed a revolt of his Basque subjects.
