Thus was the army saved from destruction by the coolness and decision of its leader, and the companies of San Marco and Verona, purged from the imputation of perfidy, were from that day embodied in a single battalion. Having so happily scotched the vipers that endangered his safety, the Duke of Urbino made his descent upon Perugia. After a short siege, during which he extended his forays as far as Spoleto and Orvieto, spreading alarm to the gates of Rome, that city capitulated on the 26th of May, receiving Carlo Baglioni as its master, and paying a ransom of 10,000 scudi, which Vermiglioli, the biographer of Gian Paolo, alleges the latter, with the bad faith usual in that age, to have shared, although the money had been raised from his own adherents. The same authority now estimates the Duke's army at twelve thousand men, with which it was his intention to make a diversion into the Florentine territory. But hearing that the Legate had taken the field, he hurried back across the Apennines, though too late to save Fossombrone and La Pergola. His wish of engaging the enemy having been foiled by their retreat into Pesaro, he had recourse to his former tactics of removing the seat of war from his own state, and turned his arms against the more wealthy towns of the Marca. Many of these, including Fabriano, Ancona, and Recanati, compounded for exemption from military violence, by paying seven or eight thousand ducats each. Corinaldo was saved by a well-timed sally, but Jesi, contrary to the wish of Francesco Maria, was sacked by his Spaniards, to whom his orderly and methodical way of laying the country under contributions, and pillaging only the refractory, was far from acceptable.
