Likewise it is claimed that in 839 his son Furtun ibn Musa led a campaign that resulted in a rout of the "king of the Gallaecians", "Loderik" or "Luzriq"[1] and he leveled the defenses of Álava.
This led to a reprisal campaign under the leadership of the emir's son, Mutarrif, and general Abd al-Wahid ibn Yazid Iskandarani.
Musa submitted and in November led his troops to Seville, helping to defeat a large army of Viking raiders who had sacked the city.
