Emboldened by his success, he attacked Uthman ibn Naissa's Aquitanian ally Duke Odo, who had just encountered Charles Martel's devastating offensive on Bourges and northern Aquitaine (731). Still managing to recruit the necessary number of soldiers, the independent Odo confronted al-Ghafiqi's forces that had broken north by the western Pyrenees, but could not hold back the Arab commander's thrust against Bordeaux. The Aquitanian leader was beaten at the Battle of the River Garonne in 732. The Umayyad force then moved north to invade Poitou in order to plunder the Basilica of Saint-Martin-de-Tours.
