After 734 Charles Martel advanced against the nobles in Burgundy and placed the region of Marseilles under the authority of his counts. [...] Charles marched afterwards to Narbonne and besieged it. Then an army of Saracens came to relieve Narbonne. Charles marched against them and defeated them along the banks of the Berre. Charles still devastated the area around Nîmes, Agde, and Béziers, but an uprising in Saxony caused him to make an expedition to hold onto that land. [...] Charles Martel had subjected the whole of Gallia, again by battles, and had to besiege Avignon and Narbonne there. He did not have the time to conquer Septimania.
It would be quite anachronistic that the Provençal aristocracy would or those whose primary interests lay in the south would welcome the extension into their region of the authority of the eastern Frankish Mayors of the Palace, or that a sense of Christian solidarity should mean more than the dictates of realpolitik. For that matter it was not with any sense of obligation to free formerly Christian lands from Islamic rule that Charles Martel launched a raid into western Provence in 737. He took Avignon, but clearly did not retain it, and advanced to besiege Narbonne, the centre of Arab control in the March. The Frankish chronicles record his victory over a relieving force sent by the governor ʿUqba, but their uniform silence makes it clear that despite this he failed to take the city itself.
