Grimoald, Childebert and Ansegisel (who had married the daughter of Pepin of Landen) were finally seized and turned over to the king of Neustria, Clovis II, who had them killed. There are two differing accounts of his death, however. Either Clovis and his mayor of the palace, Erchinoald, captured and executed him in 657 or Chlothar III annexed Austrasia in 661, deposing the young usurper and executing them both the next year.
