Imola taken, Caesar marched straight upon Forli.

There he met with a serious check; a check, moreover, which came from a woman.
Caterina Sforza, widow of Girolamo and mother of Ottaviano Riario, had retired to this town, and stirred up the courage of the garrison by putting herself, her goods and her person, under their protection.
Caesar saw that it was no longer a question of a sudden capture, but of a regular siege; so he began to make all his arrangements with a view to it, and placing a battery of cannon in front of the place where the walls seemed to him weakest, he ordered an uninterrupted fire, to be continued until the breach was practicable.
When he returned to the camp after giving this order, he found there Gian Borgia, who had gone to Rome from Ferrara and was unwilling to be so near Caesar without paying him a visit: he was received with effusion and apparently the greatest joy, and stayed three days; on the fourth day all the officers and members of the court were invited to a grand farewell supper, and Caesar bade farewell to his cousin, charging him with despatches for the pope, and lavishing upon him all the tokens of affection he had shown on his arrival.
Cardinal Gian Bargia posted off as soon as he left the supper-table, but on arriving at Urbino he was seized with such a sudden and strange indisposition that he was forced to stop; but after a few minutes, feeling rather better, he went an; scarcely, however, had he entered Rocca Cantrada when he again felt so extremely ill that he resolved to go no farther, and stayed a couple of days in the town.

Then, as he thought he was a little better again, and as he had heard the news of the taking of Forli and also that Caterina Sforza had been taken prisoner while she was making an attempt to retire into the castle, he resolved to go back to Caesar and congratulate him on his victory; but at Fassambrane he was forced to stop a third time, although he had given up his carriage for a litter.

This was his last halt: the same day he sought his bed, never to rise from it again; three days later he was dead.
His body was taken to Rome and buried without any ceremony in the church of Santa Maria del Populo, where lay awaiting him the corpse of his friend the Duke of Gandia; and there was now no more talk of the young cardinal, high as his rank had been, than if he had never existed.

Thus in gloom and silence passed away all those who were swept to destruction by the ambition of that terrible trio, Alexander, Lucrezia, and Caesar.
Almost at the same time Rome was terrified by another murder.
