Chilperic II
Following Chlothar's elevation, Chilperic and Ragamfred allied with Duke Odo of Aquitaine. In early 718, Charles led an army in Chlothar's name against the Neustrians and Aquitanians, whom he defeated at the Battle of Soissons, forcing Chilperic II to flee to Aquitaine and Duke Odo's protection. He then led the same army deep into Saxony, as far as the river Weser.
