Charles Martel - After Tours - Wars From 732-737

Wars From 732-737

Between his victory of 732 and 735, Charles reorganized the kingdom of Burgundy, replacing the counts and dukes with his loyal supporters, thus strengthening his hold on power. He was forced, by the ventures of Radbod, duke of the Frisians (719-734), son of the Duke Aldegisel who had accepted the missionaries Willibrord and Boniface, to invade independence-minded Frisia again in 734. In that year, he slew the duke, who had expelled the Christian missionaries, in the battle of the Boarn and so wholly subjugated the populace (he destroyed every pagan shrine) that the people were peaceful for twenty years after.

The dynamic changed in 735 because of the death of Odo the Great, who had been forced to acknowledge, albeit reservedly, the suzerainty of Charles in 719. Though Charles wished to unite the duchy directly to himself and went there to elicit the proper homage of the Aquitainians, the nobility proclaimed Odo's son, Hunald of Aquitaine, whose dukedom Charles recognised when the Umayyads invaded Provence the next year, and who equally was forced to acknowledge Charles as overlord as he had no hope of holding off the Muslims alone.

This naval Arab invasion was headed by Abdul Rahman's son. It landed in Narbonne in 736 and moved at once to reinforce Arles and move inland. Charles temporarily put the conflict with Hunold on hold, and descended on the Provençal strongholds of the Umayyads. In 736, he retook Montfrin and Avignon, and Arles and Aix-en-Provence with the help of Liutprand, King of the Lombards. Nîmes, Agde, and Béziers, held by Islam since 725, fell to him and their fortresses were destroyed.

He crushed one Umayyad army at Arles, as that force sallied out of the city, and then took the city itself by a direct and brutal frontal attack, and burned it to the ground to prevent its use again as a stronghold for Umayyad expansion. He then moved swiftly and defeated a mighty host outside of Narbonnea at the River Berre, but failed to take the city. Military historians believe he could have taken it, had he chosen to tie up all his resources to do so—but he believed his life was coming to a close, and he had much work to do to prepare for his sons to take control of the Frankish realm.

A direct frontal assault, such as took Arles, using rope ladders and rams, plus a few catapults, simply was not sufficient to take Narbonne without horrific loss of life for the Franks, troops Martel felt he could not lose. Nor could he spare years to starve the city into submission, years he needed to set up the administration of an empire his heirs would reign over. In addition, he faced strong opposition from regional lords such as the patrician Maurentius, from Marseille, who revolted against the Frankish leader. Moreover, the Aquitanian duke Hunald threatened his lines of communication with the north, so deciding him to withdraw from Septimania and destroy several strongholds (Béziers, Agde, etc.). He left Narbonne therefore, isolated and surrounded, and his son would return to conquer it for the Franks.

Notable about these campaigns was Charles' incorporation, for the first time, of heavy cavalry with stirrups to augment his phalanx. His ability to coordinate infantry and cavalry veterans was unequaled in that era and enabled him to face superior numbers of invaders, and to decisively defeat them again and again. Some historians believe the Battle against the main Muslim force at the River Berre, near Narbonne, in particular was as important a victory for Christian Europe as Tours.

Further, unlike his father at Tours, Rahman's son in 736-737 knew that the Franks were a real power, and that Martel personally was a force to be reckoned with. He had no intention of allowing Martel to catch him unaware and dictate the time and place of battle, as his father had. He concentrated instead on seizing a substantial portion of the coastal plains around Narbonne in 736 and heavily reinforced Arles as he advanced inland.

Abdul Rahman's son planned from there to move from city to city, fortifying as they went, and if Martel wished to stop them from making a permanent enclave for expansion of the Caliphate, he would have to come to them, in the open, where, he, unlike his father, would dictate the place of battle. All worked as he had planned, until Martel arrived, albeit more swiftly than the Moors believed he could call up his entire army. Unfortunately for Rahman's son, however, he had overestimated the time it would take Martel to develop heavy cavalry equal to that of the Muslims.

The Caliphate believed it would take a generation, but Martel managed it in five years. Prepared to face the Frankish phalanx, the Muslims were totally unprepared to face a mixed force of heavy cavalry and infantry in a phalanx. Thus, Charles again championed Christianity and halted Muslim expansion into Europe. These defeats, plus those at the hands of Leo in Anatolia, were the last great attempt at expansion by the Umayyad Caliphate before the destruction of the dynasty at the Battle of the Zab, and the rending of the Caliphate forever, especially the utter destruction of the Umayyad army at River Berre near Narbonne in 737.
