In 716, the Battle of Amblève, between Charles Martel with the Austrasians on one side and the joined forces of the Frisians and Neustrians under Ragenfrid and Chilperic II on the other side, was the first victory for Charles Martel.
In 718, Chilperic, in response, allied with Odo the Great, the duke of Aquitaine who had made himself independent during the contests in 715, but he was again defeated by Charles, at Soissons.
According to Gregory of Tours (538–594), in 493 Gundobad slew his brother Chilperic II and exiled his daughter Clotilde, who was married to the Merovingian Clovis, King of the Franks, who had just conquered northern Gaul.
