The Saracens crossed the mountains to claim Ardo's Septimania, only to encounter the Basque dynasty of Aquitaine, always the allies of the Goths. Odo the Great of Aquitaine was at first victorious at the Battle of Toulouse in 721. Saracen troops gradually massed in Septimania and in 732 an army under Emir Abdul Rahman Al Ghafiqi advanced into Vasconia, and Odo was defeated at the Battle of the River Garonne. They took Bordeaux and were advancing towards Tours when Odo, powerless to stop them, appealed to his arch-enemy, Charles Martel, mayor of the Franks. In one of the first of the lightning marches for which the Carolingian kings became famous, Charles and his army appeared in the path of the Saracens between Tours and Poitiers, and in the Battle of Tours decisively defeated and killed al-Ghafiqi. The Moors returned twice more, each time suffering defeat at Charles' hands—at the River Berre near Narbonne in 737 and in the Dauphiné in 740. Odo's price for salvation from the Saracens was incorporation into the Frankish kingdom, a decision that was repugnant to him and also to his heirs.
