October – The Frankish army crosses the Vienne River and establishes a camp at or around the partially abandoned Roman mansion or agricultural settlement, now known as 'Vieux-Poitiers' (near Châtellerault), perhaps using the Roman theatre with its substantial towers as a fortification. Charles Martel forms a defensive position across the Roman road, and fends off Muslim skirmishes during the 'seven days' stand-off, probably involving scouts, and perhaps raiders from both armies.
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, with both commanders being killed at the mouth of the River Bierre (northwest of Marseille). 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.
