Federigo's commission being now effectually fulfilled, and having no warrant for pursuing the war into the papal territory, he retired to Urbino, leaving Roberto in the field to follow up the recent victory. Although blamed for wavering during the early part of the battle, in order to fall back upon Rimini had its fortune been adverse, the latter was not slow to profit by its results, and ere November he had re-established the Malatestan sovereignty over the whole fiefs of Rimini and Fano, as well as part of the vicariat of Sinigaglia. The first fruit of Federigo's triumph was a very flattering commission from the Duke of Milan as lieutenant-general of his state, accompanied with 10,000 golden ducats in payment of his claims upon Francesco Sforza. But ere long there broke out those jealousies which chronically afflicted all Italian confederacies. The contingents of Milan and Florence, arriving too late for the battle, shared neither its glory nor its spoils, which thus fell in a great measure to the Neapolitans, whose sovereign was already regarded with no friendly eye by the haughty Lombard Prince. The liberality of the latter to the Count of Urbino was but a covert bribe to alienate him from the league, and secure his undivided services, but it was unavailing against the prior and long-established claims of the house of Aragon. Thus thwarted, Galeazzo Maria withheld from Federigo his quota of the pay promised by the allies, namely 70,000 scudi in war, and half as much in peace, and refused to contribute with them to the expense of maintaining Roberto in Rimini. This ebullition of temper, dictated by no animosity against Federigo, occasioned a diet of the powers at Florence, which, however, failed to arrange their differences. Pietro de' Medici being dead, his influence had descended to his more talented son, who, finding that the wily Venetians were courting a separate treaty with Ferdinand, hastened to urge upon his allies the importance of sinking minor differences, and maintaining the league as the best guarantee for the repose of Italy. These representations had due weight. The confederacy was renewed, and a peace concluded in December with the Pope, provided to Roberto all the territory of which his father died possessed. The following letters of Federigo to the Signory of Siena testify his interest in these arrangements, the bearings of which on the policy of Italy and Europe have been ably stated by Sismondi in his eighty-first chapter.
