The Great Captain now returned to Naples, into which city he made an entry scarcely less splendid than that into Rome; and he received at the hands of Frederic more substantial honors than those of a golden rose, in the shape of the dukedom of Santangelo, with a fief of two towns and seven dependent villages in the Abruzzo. From Naples the new duke sailed for Sicily, which was then in a state of open insurrection, in consequence of the oppressive rule of Giovanni di Nuccia, the Neapolitan viceroy. By the intervention of Gonsalvo, the inhabitants were satisfied to return to their allegiance; and order was restored without the shedding of a single drop of blood. After some further services to the state, and to the cause of peace, services both diplomatic and military, in Naples, in Sicily and in Calabria, adding in every case to his reputation as a soldier and a statesman, and above all as a great Castilian gentleman, Gonsalvo returned to his native Spain, where he was received with the applause and respect that is not always granted to great men by their own sovereigns, or even by their own countrymen. His last service to King Frederic and his people, ere he quitted the country, was no less honorable than wise. Frederic was engaged in the siege of the last city in the kingdom of Naples that refused to recognize the dominion of Aragon, the ancient and noble city of Diano, whose inhabitants, vassals of that Prince of Salerno who was attached to the Angevin cause, refused to listen to the terms which were proposed. Gonsalvo took charge of the operations; and the citizens, convinced of the hopelessness of holding out any longer against so vigorous a commander, surrendered a few days afterward at discretion. Gonsalvo, whether touched at their bravery and their forlorn condition, or merely being adverse from severity for which he saw no reason, obtained from the king favorable terms for the garrison.
