[1][2][3] The battle, which took place at the mouth of the River Berre (now in the Département of Aude), was a significant victory for Charles Martel in the military campaigns of 736–737.
The Frankish Christian army intercepted a sizeable group of Arab-Berber Muslim troops sent from Islamic Iberia and led by Uqba ibn al-Hajjaj along the banks of the River Berre, whose purpose was to relieve the Umayyad garrison during the siege of Narbonne.
[1][2][3] After their resounding victory,[1][2][3] the Frankish Christian army pursued the fleeing Arab-Berber Muslim troops into the nearby sea-lagoons, "taking much booty and many prisoners".
[6] A second Frankish expedition was led later in 739 to expel the inconvenient count Maurontius, who couldn't expect this time Andalusian relief, from Marseille and regain control of Provence.
According to Paul the Deacon's historical treatise Historia Langobardorum (787–796), the Arab Muslims retreated when they learned that Charles Martel had formed an alliance with the Lombards, leaving the Umayyad forces stationed in the area and Maurontius himself too weak to meet in open battle.
