In order to cut short such discreditable scenes, the Duke, at a council of war, announced his resolution to attempt no offensive operations until his army should be recruited by fifteen thousand Swiss, some ten thousand other troops, and forty pieces of cannon, with ample funds for their pay; adding that, as S. Angelo was provisioned for three months, there would be sufficient time for raising these reinforcements. This opinion he embodied in a memorial, which he sent on the 30th from Isola, by the Bishop of Asti, to Francis I. It is preserved by Baldi, and in Sermonetta's Letters, and offers a verbose, laboured, and inconclusive defence of his drivelling tactics. The burden of it is the inferiority of the allied force to the enemy, the probable failure of aggressive movements, and an urgent appeal that the King should come in person, as the only means of giving unanimity to a council in which each desired to lead. Indeed, the whole proceedings of the army attest the mutual jealousies and disunion of its leaders, which form the best justification of the Duke's dilatory measures, amid difficulties which he had not energy or decision to overcome. The Pontiff, thus abandoned to his fate, learned by bitter experience, "With what a weight that robe of sovereignty Upon his shoulder rests, who from the mire Would guard it, that each other fardel seems But feathers in the balance." On the 18th he wrote to the Duke of Urbino, "amid these calamities and perils," begging a safe-conduct for a messenger as far as Siena, to induce Lannoy to repair to Rome, the envoy selected for this mission being Bernardo, father of Torquato Tasso. The Viceroy willingly responded to this summons, hoping to succeed Bourbon in command of the imperialists. But finding the Prince of Orange already chosen by the army to that post, he in disgust kept aloof from the capitulation, which was signed on the 5th of June, by the intervention of Gattinara. Its principal stipulations were these: 1. A safe-conduct to Naples for his Holiness, and such of the cardinals as chose to go, upon payment of 150,000 golden scudi, two thirds whereof within six days, the remainder on the expiry of twenty. 2. Security for the personal property within the castle, upon payment of as much more, for which hostages were to be given until it could be raised by a general impost or otherwise. 3. The removal of all censures from the Colonna, and their restoration to their estates and dignities. 4. The immediate surrender of S. Angelo, Civita Vecchia, Ostia, and Civita Castellana, with the further cession of Parma, Piacenza, and Modena to the Emperor, as an inducement for the army to evacuate Rome. This treaty was signed by nine cardinals, four bishops, and eighteen imperialist officers, and the castle was forthwith consigned to a guard of the invaders, in whose hands the Pontiff and his court remained virtually prisoners.[16] [Footnote 16: Vat.
