It was a glorious day on which François, after taking a tender farewell of Diane, set forth with his host from Aix—and it was a gallant sight to see the king, arrayed in his splendid armour, and mounted on his war-horse, issue from the gates accompanied by the flower of the French chivalry. Proceeding by forced marches along the valley of the Durance to Briançon, he crossed the Alps without difficulty by the Pass of Susa.
Enthusiastic was his delight at finding himself once more in Italy at the head of an army which he deemed irresistible. Without encountering any obstruction he pressed on to Vercelli, where he ascertained the movements of the enemy.
The Imperial army, it appeared, had been greatly reduced by the forced march from Marseilles, and had also sustained heavy losses of baggage and artillery. Two thousand men had been thrown into Alexandria. Lodi, Pizzighettone, and Como were also strongly garrisoned, but by far the most formidable preparations had been made at Pavia, the defence of which had been committed, as during Bonnivet's campaign in the previous year, to Antonio de Leyva. The garrison of Pavia was now augmented by five thousand German lanz-knechts under De Hohenzollern, five hundred Spanish soldiers, and three hundred lances.
Bourbon and Pescara, accompanied by Lannoy, had marched with the rest of the army to Milan, and thither François determined to follow them.
Two days after quitting Vercelli the king appeared before the city. His approach could not, of course, be concealed from the Imperialists, and a long counsel was held by Bourbon and the other chiefs as to the possibility or prudence of holding the place against him. It was decided that, considering the enfeebled condition of the troops and the infected state of the city, there was no alternative but to abandon it. Defence under such circumstances was, indeed, impossible, and had the Imperial generals attempted to sustain a siege, the whole army would probably have been destroyed by the pestilence.
Accompanied by Sforza, Pescara, and the others, Bourbon therefore quitted the city, and proceeded to Lodi. Just as the last of the Imperialists marched out of Milan by the Porta Romana, a detachment of the French army, under La Trémouille, entered the city by the Porta Vercellina.
The satisfaction which François would have felt at this easy conquest was marred by the dismal aspect of the plague-stricken city. Ghastly evidences of the presence of the Destroyer met his eye at every turn. The deserted streets, the closed houses, the mournful air of the populace—all conspired to cast a gloom over him.
Just then the pestilence was at its height. On the very day on which he entered Milan with his host, several hundreds of persons had died, and as many more were sick. The hospitals and lazar-houses were filled to overflowing, and the pits surcharged with dead. No remedies could be found to arrest the progress of the scourge. Almost all who were seized by it perished, and the city was more than half depopulated.
No wonder that François blamed himself for his rashness in exposing his army to so much peril. But he resolved that his stay in Milan should be brief—no longer than was absolutely necessary to resume his authority—and that all possible precautions should be taken against contagion. With this view he secluded himself within the ducal palace, and ordered the army to encamp without the walls.
