Odo still found the opportunity to save his grip on Aquitaine by warning the rising Frankish commander Charles of the impending danger against the Frankish sacred city of Tours. Umayyad forces were defeated in the Battle of Poitiers in 732, considered by many the turning point of Muslim expansion in Gaul. With the death of Odo in 735 and after putting down the Aquitanian detachment attempt led by duke Hunald, Charles Martel went on to deal with Burgundy (734, 736) and the Mediterranean south of Gaul (736, 737).
