 After Docibilis I of Gaeta broke with the pope over the Saracens, with whom Docibilis was allied, John authorised Pandenulf to seize papal possessions governed by Naples.Pandenulf's troops reduced the Gaetans to control only of their own peninsula, but Docibils called in the Saracens of Agropoli and retook Fondi, ravaging the papal territory.Pandenulf was called back by events in Capua, however, and John was forced to make a treaty with Docibilis whereby the latter became a papal vassal.
