This decision was not accepted by all family members. Carloman had consented to the temporary tenancy of his own share, which he intended to pass on to his son, Drogo, when the inheritance should be settled at someone's death. By the Pope's decision, in which Pepin had a hand, Drogo was to be disqualified as an heir in favour of his cousin Charles. He took up arms in opposition to the decision and was joined by Grifo, a half-brother of Pepin and Carloman, who had been given a share by Charles Martel, but was stripped of it and held under loose arrest by his half-brothers after an attempt to seize their shares by military action. Grifo perished in combat in the Battle of Saint-Jean-de-Maurienne while Drogo was hunted down and taken into custody.
