The pope now found himself in very great straits; for the city of Rome was disturbed by factions and the country covered with enemies. But acting with courage and resolution, he appointed Roberto da Rimino to take the command of his forces; and having sent for him to Rome, where his troops were assembled, told him how great would be the honor, if he could deliver the church from the king's forces, and the troubles in which it was involved; how greatly indebted, not only himself, but all his successors would be, and, that not mankind merely, but God himself would be under obligations to him. The magnificent Roberto, having considered the forces and preparations already made, advised the pope to raise as numerous a body of infantry as possible, which was done without delay. The duke of Calabria was at hand, and constantly harassed the country up to the very gates of Rome, which so roused the indignation of the citizens, that many offered their assistance to Roberto, and all were thankfully received. The duke, hearing of these preparations, withdrew a short distance from the city, that in the belief of finding him gone, the magnificent Roberto would not pursue him, and also in expectation of his brother Federigo, whom their father had sent to him with additional forces. But Roberto, finding himself nearly equal to the duke in cavalry, and superior in infantry, marched boldly out of Rome and took a position within two miles of the enemy. The duke, seeing his adversaries close upon him, found he must either fight or disgracefully retire. To avoid a retreat unbecoming a king's son, he resolved to face the enemy; and a battle ensued which continued from morning till midday. In this engagement, greater valor was exhibited on both sides than had been shown in any other during the last fifty years, upward of a thousand dead being left upon the field. The troops of the church were at length victorious, for her numerous infantry so annoyed the ducal cavalry, that they were compelled to retreat, and Alfonso himself would have fallen into the hands of the enemy, had he not been rescued by a body of Turks, who remained at Otranto, and were at that time in his service. The lord of Rimino, after this victory, returned triumphantly to Rome, but did not long enjoy the fruit of his valor; for having, during the heat of the engagement, taken a copious draught of water, he was seized with a flux, of which he very shortly afterward died.
The pope caused his funeral to be conducted with great pomp, and in a few days, sent the Count Girolamo toward Citta di Castello to restore it to Lorenzo, and also endeavor to gain Rimino, which being by Roberto's death left to the care of his widow and a son who was quite a boy, his holiness thought might be easily won; and this certainly would have been the case, if the lady had not been defended by the Florentines, who opposed him so effectually, as to prevent his success against both Castello and Rimino.
While these things were in progress at Rome and in Romagna, the Venetians took possession of Figaruolo and crossed the Po with their forces. The camp of the duke of Milan and the marquis was in disorder;for the count of Urbino having fallen ill, was carried to Bologna for his recovery, but died. Thus the marquis's affairs were unfortunately situated, while those of the Venetians gave them increasing hopes of occupying Ferrara. The Florentines and the king of Naples used their utmost endeavors to gain the pope to their views; and not having succeeded by force, they threatened him with the council, which had already been summoned by the emperor to assemble at Basle; and by means of the imperial ambassadors, and the co-operation of the leading cardinals, who were desirous of peace, the pope was compelled to turn his attention toward effecting the pacification of Italy. With this view, at the instigation of his fears, and with the conviction that the aggrandizement of the Venetians would be the ruin of the church and of Italy, he endeavored to make peace with the League, and sent his nuncios to Naples, where a treaty was concluded for five years, between the pope, the king, the duke of Milan, and the Florentines, with an opening for the Venetians to join them if they thought proper.
When this was accomplished, the pope intimated to the Venetians, that they must desist from war against Ferrara. They refused to comply, and made preparations to prosecute their design with greater vigor than they had hitherto done; and having routed the forces of the duke and the marquis at Argenta, they approached Ferrara so closely as to pitch their tents in the marquis's park.
