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.
"I believe your lordships have learned the rupture of the most serene and illustrious league, and how this came about, whereat I feel the utmost dissatisfaction and regret. Not that I have on my own part to lament any want of such exertion and action for its continuance and union as my duty demanded, but that fortune so willed it. Yet I entertain a hope and assurance that the peace of Italy will not thereby be compromised; indeed matters may, as often happens, turn out eventually better than they were at first." [May 8, 1470.]
"Mighty and potent Lords, dearest Fathers,
"Your lordships' letters by this courier have afforded me much pleasure, as they must ever in all circumstances do, but especially when it is in my power to perform something acceptable to your lordships, or to comply with any request of yours. I am well assured, as your lordships observe, that you are fully informed up to this time of the transactions among the Italian powers, and of the difficulties that have arisen; of these, therefore, I need say nothing. I do not understand that as yet matters have assumed a definite shape, or been finally decided upon; although it is quite possible that something has been concluded at Naples, where the ambassadors of all these states are assembled, but there has not yet been time for me to hear of it. Thus much I may, however, say to your lordships, that I hope things will at all events issue in a satisfactory peace, towards which these views of the Turk ought to incline every one, for all tempers, however rough or obdurate, ought at this juncture to yield and bend for the general advantage of the Christian religion. I am also able to assure your lordships that your republic and its honour and character must derive quite as much satisfaction, utility, and benefit from peace and tranquillity as any other community, seeing the affection generally entertained for it, especially by the serene King. I commend myself to your lordships. From Urbino, the 7th of July, 1470.
"Federigo Count of Montefeltro, Urbino, and Durante."[152]
The duplicity of Italian diplomacy has passed into a proverb, and by none was it more constantly practised than by the successors of St. Peter. The investiture of Roberto, although a specific stipulation of the new league, was constantly evaded by Paul, until, after months of procrastination, death released his Holiness from the engagement. His successor, Sixtus IV., was a friend of Federigo and of the Neapolitan Monarch, and through their mediation Malatesta obtained prompt performance of the obligation. Thus established in a seigneury, long the heritage of bastards, Roberto allied himself more intimately with the Count of Urbino, by espousing, on the 28th of March, 1472, his daughter Elisabetta (or Isabella, for the names were synonymous), then about nine years old; and thus were happily closed the long feuds of these rival races.[153]
