866 – 911
From the first clashes in 866 to the final fighting in 911, find the full chronology of this conflict below, with the forces engaged, commanders and consequences for France in each battle.
Era : Early Middle Ages
- 866 Battle of Brissarthe Victory
On July 2, 866, Robert the Strong, Count of Tours and Marquis of Neustria, engaged a coalition of Vikings and Bretons in the region of Brissarthe, north of Angers. The invaders, who regularly ravaged the Loire Valley, had established themselves in a fortified camp after an incursion. Robert gathers his forces and attacks by surprise. The fight was fierce: the Franks managed to repel the attackers and inflict heavy losses on the Vikings. However, Robert was mortally wounded during the confrontation, which gave the battle a tragic significance despite its favorable outcome for the Franks. The victory prevents further immediate incursions into Anjou and strengthens the military reputation of the Robertian line.
- 881 Battle of Saucourt-en-Vimeu Victory
On August 3, 881, Kings Louis III and Carloman II, young Carolingian heirs, gathered a Frankish army to confront a powerful Viking band which was devastating Picardy. The invaders, made up of roving Danish contingents, had carried out a series of murderous raids in the Somme valley. The confrontation, fought near Saucourt-en-Vimeu, took the form of an extremely bloody pitched battle. The Frankish troops, disciplined and coordinated, managed to overwhelm the enemy after violent exchanges. Contemporary sources, notably the heroic poem *Ludwigslied*, perhaps exaggerate the figures, but mention the death of several thousand Vikings on the battlefield. This victory is considered one of the greatest Carolingian military successes against the Scandinavian invaders.
- 911 Siege of Chartres Victory
In 911, Chartres, a fortified city in the kingdom of West Francia, was besieged by Rollo's Viking forces. After several days of siege, the defenders led by Robert I – Duke of the Franks and brother of the late King Eudes – organized a decisive exit. The simultaneous arrival of the royal army of Charles the Simple took the besiegers from behind. The Vikings, surprised and surrounded, suffered heavy losses and abandoned the siege. This Frankish victory puts an end to the series of Viking raids on the Loire and begins the lasting pacification of the north of the kingdom.
