 Charles Martel replied to the embassy and acknowledged the gifts, but was unwilling to offer aid against the Lombards, who were helping him against the Saracens.Accordingly, the successor of Gregory III, Pope Zachary, changed the policy that had been previously followed toward the Lombards.He formed an alliance with Liutprand against Transamund, and in 741 received in return the four castles as the result of a personal visit to the camp of the king at Terni.
