By place

Europe

• Battle of Avignon: Frankish forces under Charles Martel, Merovingian Mayor of the Palace, retake Avignon from the Muslim forces, and destroy the Umayyad stronghold. Charles sends his brother Childebrand I, duke of Burgundy, to besiege the city. After his arrival, Charles leads the Frankish troops by using rope ladders and battering rams to attack the fortified walls, which are burned to the ground following its capture.<ref>Halsall, Guy (2003).

• Battle of Narbonne: Frankish forces under Charles Martel besiege Narbonne, occupied by a Umayyad garrison, but are unable to retake the fortress city. A Lombard army under King Liutprand crosses the Alps, to aid Charles in expelling the Muslims from Septimania. Meanwhile Maurontus, duke or count of Provence, raises a revolt from his unconquered city of Marseille, and threatens the rear of the Franks.<ref>Template:Cite book</ref>
• Battle of the River Berre: Frankish forces sent by Charles Martel intercept a large Muslim army sent from Al-Andalus, (modern Spain) sent by Uqba ibn al-Hajjaj to relieve the siege of Narbonne. Both sides suffer heavy losses at the battlefield near the mouth of the River Berre (a short distance south of Narbonne). Some of the Muslims rush back to their ships, and some penetrate through the Frankish forces and make it to the city, effectively saving it from the Franks.<ref name="Fouracre2000p97">Template:Cite book</ref>
