 However, historians have discredited the importance of this victory.Marios Costambeys, Matthew Innes and Simon MacLean all show that the Tertry victory did not establish solid authority over Neustria immediately, evidenced by the fact that Pippin immediately installed 'Norbert, one of his followers' (as written in the "LHF") and then his son Grimoald in 696 to ensure continued influence.Pippin II then became overall mayor of the royal palace under Theuderic II, becoming mayor of Austrasia, Neustria and Burgundy.
