On the evening of the 27th of February, while the joy bells were ringing in the Milanese churches in honour of the French king's triumph, the duke sent for the Venetian ambassadors.
"I have had bad news," he said. "Naples is lost, and the French king has been joyfully welcomed by the people. I am ready to do whatever the Republic desires. But there is no time to waste; we must act at once."
All eyes now turned to Lodovico as the only man who could save Italy from the French invaders. The emperor and the Venetians had been urging him to declare war against France for the last eight weeks, and now Ferrante of Aragon, in his despair, appealed to him by the Sforza blood that flowed in both their veins to deliver him and his kingdom from the dominion of the foreigner. The duke himself could not feel safe as long as Louis of Orleans remained at Asti, and declared that he was ready to place himself at the head of a league for the defence of Italy. He wrote to congratulate Commines, the French ambassador at Venice, on his master's success, but the same day he sent the Bishop of Como and Francesco Bernardino Visconti to Venice, there to negotiate a new league between himself, the Signoria, the Pope, the King of the Romans, and the King and Queen of Spain. The presence of the German and Spanish ambassadors, as well as the arrival of the two new Milanese envoys, excited Commines' suspicions, while the long faces and terror-struck air of the Venetian senators, when the news from Naples arrived, reminded him of the Romans after the defeat of Cannæ. But so well was the secret kept that he knew nothing of the league until after it had been signed, late on the night of the 31st of March, in the bedchamber of the old Doge. Early the next morning he was summoned to the palace, and, in the presence of a hundred senators, solemnly informed of the new treaty.
"Magnificent ambassador," said the prince, "our friendship for your master makes it our duty to inform you of all that concerns the state. Know, then, that yesterday, in the name of the Holy Spirit, of the glorious Virgin Mary, and the blessed Evangelist Monsignore S. Marco, our patron, a league has been concluded for the protection of the Church and the defence of the Holy Roman Empire and your own states, between his Holiness the Pope, his Majesty the King of the Romans, the King and Queen of Spain, our Signoria, and the Duke of Milan. Tell this, we pray you, to your Most Christian Majesty." Before the prince had done speaking, Commines heard the bells of St. Mark's ringing to celebrate the new league, and, still dazed by the unexpected news, he stammered out, "What will happen to my king? Will he be able to return to France?"
"Certainly," replied the prince, "if he comes as a friend to the league."
Without another word, Commines left the palace, but as he went down the grand staircase, he asked the secretary who accompanied him to repeat the Doge's words, since he could hardly take them in. Then he told his gondoliers to row him back to his house, near S. Giorgio Maggiore, and on the way he met the ambassador of Naples, in a fine new robe, with a smiling face, as he well might have, "for this," adds Commines, "was great news for him." Marino Sanuto, who narrates the incident, was much struck by Commines' rage and dismay, and, like a true Venetian, remarks contemptuously, "He did not know how to dissimulate his feelings, as one should do in such a case." And, in the same spirit, he goes on to admire the presence of mind displayed by the Milanese ambassadors, who to all Commines' remonstrances replied courteously, that of course their duke had nothing to do with all this. "They acted," he adds, "as the wise act in the government of states. They persuade their enemies that they mean to do one thing, and then they do another."
At night all Venice was illuminated, and from his covered gondola the French ambassador saw the fireworks and the banquetings that were held at the palaces of the other envoys. He understood what it all meant, and trembled for his king's safety. But he lost no time, and sent warnings both to Orleans at Asti and to Charles at Naples, of the coming storm. A week or two later he left Venice, and went to meet Charles at Florence. On Palm Sunday, the 10th of April, the League was solemnly proclaimed on the Piazza of St. Mark, and all the ambassadors marched in procession round the square, while images of united Italy, and of all the kings and princes of the League, were carried about in triumph, and the golden rose was given by the Pope to the Venetian ambassador in Rome. "To-day," said the Duke of Milan, "will see the dawn of the peace and prosperity of Italy."
King Charles, meanwhile, unconscious of the dangers that threatened to impede his return home, was revelling in the delights of Naples, and holding jousts and banquets in the sunny gardens and fair palaces of that enchanted bay. "My brother," he wrote to the Duke of Bourbon, "this is the divinest land and the fairest city that I have ever seen. You would never believe what beautiful gardens I have here. So delicious are they, and so full of rare and lovely flowers and fruits, that nothing, by my faith, is wanting, except Adam and Eve, to make this place another Eden."
While the king and his nobles were eating off gold and silver plate and drinking out of jewelled goblets in King Alfonso's tapestried halls, the French soldiers were to be seen lying about in the streets, intoxicated with the strong and luscious wines of Southern Italy. The whole army was given over to luxury and vice, and the outrages which the troops committed soon made them hated by the fickle populace, who a few weeks before had welcomed them as deliverers from the tyrant's yoke. "From the moment of the king's arrival until his departure," writes Commines, "he thought of nothing but pleasure, and those about him only cared to seek their own profit. His youth may excuse him, but for his servants there could be no excuse." The news of the league between the powers came to startle Charles out of this fool's paradise. On the 8th of April, the Count of Caiazzo was suddenly recalled to Milan, and when Charles asked Lodovico to send him Messer Galeazzo instead, the duke replied curtly that he had need of him at home. By degrees the king began to realize the formidable combination which had arisen against him, and prepared to march northward with the bulk of his army, leaving the Duke of Montpensier with a few hundred French troops and some thousand Swiss mercenaries to defend his newly conquered kingdom. On the 20th of May, he finally left Naples, and on the 1st of June entered Rome by the Latin gate, two days after the Pope had fled to Orvieto. Almost at the same moment, King Ferrante returned to Calabria, and his subjects flocked to join the old banner of the house of Aragon.
Lodovico's first step was to send Galeazzo di Sanseverino with a body of newly raised troops against Asti, on the 19th of April, and to summon the Duke of Orleans to surrender the town and to drop the title of Duke of Milan. In this he was supported by the Emperor Maximilian, who sent an imperious order to Louis forbidding him to assume the title, on pain of forfeiting his fief of Asti. Orleans replied proudly that Asti formed part of his heritage, and that he was ready to defend it to the last drop of his blood against Signor Lodovico or any other foe. At the same time he sent an urgent appeal to the Duke of Bourbon for reinforcements, and prepared to act on the offensive.
