While digressing on this impressive lineage, the chronicler William of Apulia in his The Deeds of Robert Guiscard says that he "though now only a young man, already shows courage worthy of an adult."
He succeeded to his father's dominions at a very young age and immediately he and his family were thrown out of their city by the capricious Capuans.
The two Rogers came, the former in exchange for the city of Naples and the latter for Richard's recognition of Apulian suzerainty, in May 1098 and besieged Capua for forty days.
With the aid of Sicilian Saracens, the city fell and the prince was reinstated, Apulian suzerainty acknowledged, and the pope and the count withdrew to Salerno.
Though he had accepted doing homage to the Hauteville duke of Apulia, his successors did not and Capua returned to de facto independence under them.
