An appeal to the Pope failed. Although Julius III. was Sienese on his mother’s side, he coldly recommended an unconditional surrender to the Caesarian Majesty. Once more the city was solemnly offered up to the Madonna; there were wild, useless appeals to Venice and the Duke of Ferrara to interpose. Then, no help being forthcoming from heaven or earth, the starving Sienese capitulated to the Emperor through the Duke of Florence, in April 1555. On April 21st the French marched out of the Porta Romana, Montluc receiving a well-deserved ovation from the enemy. With them went a number of Florentine exiles and others, “exiles and rebels to the State of the Emperor, the King of England (who was King Philip) and the Duke of Florence”; for Montluc had insisted upon a clause in their favour being inserted into the capitulation, and the Marchese di Marignano himself had no desire of glutting the Medicean headsman with more blood. With them went a number of Sienese headed by Mario Bandini (the last Captain of the People in free Siena), Fabio Spannocchi, who was one of the Priors, and Giulio Vieri, one of the three Gonfalonieri. These were about 800 in all, men, women and children; the old women and some of the children went on carriage mules, which Marignano had provided at Montluc’s request, the rest tramping wearily on foot. The Spaniards had some pity, and succoured them with food on the way. “I had seen a sad parting,” writes Montluc, “at the turning out the useless mouths; but I saw as sad a one at the separation of those who went out with us and those who remained behind. In my life I never saw so sad a farewell; so that although our soldiers had in their own persons suffered to the last extremes, yet did they infinitely regret this woful parting, and that they had not the power to defend the liberty of these people, and I more than all the rest, who could not without tears behold this misery and desolation of a people, who had manifested themselves so devout for the conservation of their liberty and honour.”
Then, suddenly, all the bells of the churches and towers began to ring. The imperialists—Spaniards, Italians, Germans—marched in by the same gate. They entered quietly and in an orderly fashion, but made a great shouting and uproar when they reached the Campo. Surrounded by a splendidly equipped guard of German halberdiers, the Marchese di Marignano rode to the Duomo and had the Mass of the Holy Spirit solemnly sung. But the choristers broke down in sobs and tears, and the lamentations of the people drowned the music. Vast supplies of provisions, brought from Florence, appeared in the Campo; white bread and wine, grain, fresh and salt meat, and eggs. The starving Sienese, rushing to buy, instantly swept the piazza clear of these provisions, like the advent of a sudden whirlwind.
For some while the ultimate fate of the once mighty Republic hung in doubt. Cosimo had conquered as the lieutenant of the Emperor, and the latter first invested his own son, Philip II. of Spain, with Siena and its dominion as a vacant fief of the Empire. Philip ruled it for two years by means of the tyrannical Cardinal of Burgos, who, in defiance of the articles of the capitulation, began to build a fortress and filled the prisons with suspected persons. There was even some talk of ceding the Sienese State to Pope Paul IV., that he might invest his nephews, the Caraffa, with it. But at length Cosimo de’ Medici had his will, and in July 1557, he obtained from Philip the investiture of Siena, its city and dominion, to be held as a fief from the King of Spain. But the Spanish monarch reserved to himself the seaboard of the late Republic—including Talamone, Orbetello, Port’ Ercole and Porto Santo Stefano—which henceforth, until the eighteenth century, formed what were known as the Spanish Praesidia.[130]
But Montalcino still held out under French protection. Mario Bandini had carried off the public seals; and, although he sent these back after he had copied them, the Sienese in Montalcino, declaring that ubi cives, ibi patria, still represented the old Republic of Siena, coined money, and for some time kept a large portion of the Sienese State in obedience to them and France. Mario Bandini died there in 1558; that other hero of the last days of the Republic, Enea Piccolomini, had died a month before the capitulation of Siena itself. At length, the treaty of Câteau Cambresis, which decided the fate of Italy, decided the destinies of Montalcino as well. The heroic little Republic sent two ambassadors to Cambresis, Bernardino Buoninsegni and Annibale Buonsignori, pleading either for liberty or for the rule of France. That failing, they capitulated in August 1559, to Spain and Cosimo upon honourable terms, and the Republic of Siena was a thing of the past.
In 1561 Cosimo, Duke of Florence and Siena (he did not become Grand Duke until 1570), made his triumphant entry into Siena. Henceforth he ruled the city by means of a lieutenant-general and a Balìa appointed by himself; the other forms of republican government were preserved, as the Duke was anxious to attract back to Siena those whom Spanish brutality had driven away, but with hardly the shadow of any political authority. The great grand-ducal citadel of Santa Barbara, now that most pleasant of lounging-places at sunset, tells its own story.
