Venice and in view of the circumstance that the republic had sent to Rome the arrears of tribute due from his fief, and anxious to conciliate the Pope, received and entertained Cesare very cordially.
At Forli the case of Imola was practically repeated. Notwithstanding that the inhabitants were under the immediate eye of the formidable countess, and although she sent her brother, Alessandro Sforza, to exhort the people and the Council to stand by her, the latter, weary as the rest of the oppressive tyranny of her family, dispatched their representatives to Cesare to offer him the town.
The Countess's valour was of the sort that waxes as the straits become more desperate. Since the town abandoned and betrayed her, she would depend upon her citadel, and by a stubborn resistance make Cesare pay as dearly as possible for the place. To the danger which she seems almost eager to incur for her own part, this strong-minded, comely matron will not subject the son she has kept beside her until now; and so she packs Ottaviano off to Florence and safety. That done, she gives her mutinous subjects a taste of her anger by attempting to seize half a dozen of the principal citizens of Forli. As it happened, not only did this intent miscarry, but it went near being the means of involving her in battle even before the duke's arrival; for the people, getting wind of the affair, took up arms to defend their threatened fellow-citizens.
She consoled herself, however, by seizing the persons of Nicolo Tornielli and Lodovico Ercolani, whom the Council had sent to inform her that their representatives had gone to Cesare with the offer of the town. Further, to vent her rage and signify her humour, she turned her cannon upon the Communal Palace and shattered the tower of it.
Meanwhile Cesare advanced. It was again Tiberti who now rode forward with his horse to demand the surrender of Forli. This was accorded as readily as had been that of Imola, whereupon Cesare came up to take possession in person; but, despite the cordial invitation of the councillors, he refused to enter the gates until he had signed the articles of capitulation.
On December 19, under a deluge of rain, Cesare, in full armour, the banner of the Church borne ahead of him, rode into Forli with his troops. He was housed in the palace of Count Luffo Nomaglie (one of the gentlemen whom Caterina had hoped to capture), and his men were quartered through the town. These foreign soldiers of his seem to have got a little out of hand here at Forli, and they committed a good many abuses, to the dismay and discomfort of the Citizens.
Sanuto comments upon this with satisfaction, accounting the city well served for having yielded herself up like a strumpet. It is a comment more picturesque than just, for obviously Forli did not surrender through pusillanimity, but to the end that it might be delivered from the detestable rule of the Riarii.
The city occupied, it now remained to reduce the fortress and bring its warrior-mistress to terms. Cesare set about this at once, nor allowed the Christmas festivities to interfere with his labours, but kept his men at work to bring the siege-guns into position. On Christmas Day the countess belatedly attempted a feeble ruse in the hope of intimidating them. She flew from her battlements a banner, bearing the device of the lion of St. Mark, thinking to trick Cesare into the belief that she had obtained the protection of Venice, or, perhaps, signifying thus that she threw herself into the arms of the republic, making surrender of her fiefs to the Venetians to the end that she might spite a force which she could not long withstand—as Giovanni Sforza had sought to do.
But Cesare, nowise disturbed by that banner, pursued his preparations, which included the mounting of seven cannons and ten falconets in the square before the Church of St. John the Baptist. When all was ready for the bombardment, he made an effort to cause her to realize the hopelessness of her resistance and the vain sacrifice of life it must entail. He may have been moved to this by the valour she displayed, or it may have been that he obeyed the instincts of generalship which made him ever miserly in the matter of the lives of his soldiers. Be that as it may, with intent to bring her to a reasonable view of the situation, he rode twice to the very edge of the ditch to parley with her; but all that came of his endeavours was that on the occasion of his second appeal to her, he had a narrow escape of falling a victim to her treachery, and so losing his life.
She came down from the ramparts, and, ordering the lowering of the bridge, invited him to meet her upon it that there they might confer more at their ease, having, meanwhile, instructed her castellan to raise the bridge again the moment the duke should set foot upon it. The castellan took her instructions too literally, for even as the duke did set one foot upon it there was a grind and clank of machinery, and the great structure swung up and clattered into place. The duke remained outside, saved by a too great eagerness on the part of those who worked the winches, for had they waited but a second longer they must have trapped him.
Cesare returned angry to Forli, and set a price upon Caterina's head—20,000 ducats if taken alive, 10,000 if dead; and on the morrow he opened fire. For a fortnight this was continued without visible result, and daily the countess was to be seen upon the walls with her castellan, directing the defences. But on January 12, Cesare's cannon having been concentrated upon one point, a breach was opened at last. Instantly the waiting citizens, who had been recruited for the purpose, made forward with their faggots, heaping them up in the moat until a passage was practicable. Over this went Cesare's soldiers to force an entrance.
A stubborn fight ensued within the ravelin, where the duke's men were held in check by the defenders, and not until some four hundred corpses choked that narrow space did the besieged give ground before them.
Like most of the Italian fortresses of the period, the castle of Forli consisted of a citadel within a citadel. In the heart of the main fabric—but cut off from it again by its own moat—arose the great tower known as the Maschio. This was ever the last retreat of the besieged when the fortress itself had been carried by assault, and, in the case of the Maschio of the Citadel of Forli, so stout was its construction that it was held to be practically invulnerable.
Had the countess's soldiers made their retreat in good order to this tower, where all the munitions and provisions were stored, Cesare would have found the siege but in the beginning; but in the confusion of that grim hour, besieged and besiegers, Borgian and Riarian, swept forward interlocked, a writhing, hacking, bleeding mob of men-at-arms. Thus they flung themselves in a body across the bridge that spanned the inner moat, and so into the Maschio, whilst the stream of Cesare's soldiers that poured uninterruptedly across in the immediate wake of that battling mass rendered it impossible for the defenders to take up the bridge.
Within the tower the carnage went on, and the duke's men hacked their way through what remained of the Forlivese until they had made themselves masters of that inner stronghold whither Caterina had sought her last refuge.
A Burgundian serving under the Bailie of Dijon was the first to come upon her in the room to which she had fled with a few attendants and a handful of men, amongst whom were Alessandro Sforza, Paolo Riario, and Scipione Riario—this last an illegitimate son of her first husband's, whom she had adopted. The Burgundian declared her his prisoner, and held her for the price that had been set upon her head until the arrival of Cesare, who entered the citadel with his officers a little while after the final assault had been delivered.
Cesare received and treated her with the greatest courtesy, and, seeing her for the moment destitute, he presented her with a purse containing two hundred ducats for her immediate needs. Under his escort she left the castle, and was conducted, with her few remaining servants, to the Nomaglie Palace to remain in the Duke's care, his prisoner. Her brother and the other members of her family found with her were similarly made prisoners.
After her departure the citadel was given over to pillage, and all hell must have raged in it if we may judge from an incident related by Bernardi in his chronicles. A young clerk, named Evangelista da Monsignane, being seized by a Burgundian soldier who asked him if he had any money, produced and surrendered a purse containing thirteen ducats, and so got out of the mercenaries' clutches, but only to fall into the hands of others, one of whom again declared him a prisoner. The poor youth, terrified at the violence about him, and eager to be gone from that shambles, cried out that, if they would let him go, he would pay them a ransom of a hundred ducats.
Thereupon "Surrender to me!" cried one of the soldiers, and, as the clerk was about to do so, another, equally greedy for the ransom, thrust himself forward. "No. Surrender to me, rather," demanded this one.
The first insisted that the youth was his prisoner, whereupon the second brandished his sword, threatening to kill Evangelista. The clerk, in a panic, flung himself into the arms of a monk who was with him, crying out for mercy, and there in the monk's arms he was brutally slain, "to put an end," said his murderer, "to the dispute."
Forlimpopoli surrendered a few days later to Yves d'Allegre, whom Cesare had sent thither, whilst in Forli, as soon as he had reduced the citadel, and before even attempting to repair the damage done, the duke set about establishing order and providing for the dispensation of justice, exerting to that end the rare administrative ability which not even his bitterest detractors have denied him.
He sent a castellan to Forlimpopoli and fetched from Imola a Podesta for Forli.
