With this Cesare refused to comply, and, as a result, he was detained by the captain of the navy, in obedience to the instructions from Julius.

At the same time the Pope broke the last link of the treaty with Cesare by appointing a new Governor of Romagna in the person of Giovanni Sacchi, Bishop of Ragusa.

He commanded the latter to take possession of the Romagna in the name of the Church, and he issued another brief--the third within three weeks--demanding the State's obedience to the new governor.
On November 26, Remolino, who had been at Ostia with Cesar; came to Rome, and, throwing himself at the feet of the Pontiff, begged for mercy for his lord, whom he now accounted lost.

He promised Julius that Cesare should give him the countersigns of the strongholds, together with security for their surrender.

This being all that the Pope could desire, he issued orders that Cesare be brought back to Rome, and in Consistory advised the Sacred College--by way, no doubt, of exculpating himself to men who knew that he was refusing to pay the price at which he had bought the Papacy--that the Venetians in the Romagna were not moving against the Church, but against Cesare himself--wherefore he had demanded of Cesare the surrender of the towns he held, that thus there might be an end to the war.
It was specious--which is the best that can be said for it.
As for putting an end to the war, the papal brief was far indeed from achieving any such thing, as was instantly plain from the reception it met with in the Romagna, which persisted in its loyalty to Cesare in despite of the very Pope himself.
