In 751, according to the "Chronicle of Moissac", Waiofar sacked the city of Narbonne ("Narbonam depraedat"), the centre of Islamic rule north of the Pyrenees, having been conquered by the Arabs in 720. The following year several other formerly Visigothic cities north of the Pyrenees, under a certain Count Ansemund, went over to the Franks. Between 752 and 759, Pepin's forces besieged Narbonne. For reasons unknown, Waiofar attacked Pepin's forces while they were camped by the city, "as his father had attacked Charles Martel" in the words of the "Annals of Aniane". Only the local sources, the "Chronicle of Moissac" and "Annals of Aniane", record this attack. Although the "Chronicle of Uzès" records that the Rouergue was conquered by Pepin in 754, during the siege of Narbonne, it is more likely that its conquest was effected with the assistance of the local Visigoths only after the fall of Narbonne (a Gothic city prior to the Arab conquest).
