MIRABELLO.

On quitting Lodi, the Imperial army consisted of upwards of twenty-one thousand men, more than half of whom had been raised by Bourbon, The lanz-knechts were commanded by Von Frundsberg, the reiters by Marx Sittich d'Ems, and the Burgundian light horse by the Comte de Salms.

Pescara's chief reliance was upon a corps of Basque arquebussiers, whom he had trained to rush upon the enemy, discharge their pieces, and retreat with extraordinary rapidity. These Basques formed a corps fifteen hundred strong, and were all unerring marksmen. Moreover, they were armed with short sharp swords, which they could fix on the top of their arquebusses, and use with terrible effect against cavalry.

During its march the army extended for nearly three leagues. The vanguard was commanded by Pescara, with whom were the best of the Spanish cavalry, and the before-mentioned Basque arquebussiers. Then came the Marquis del Vasto with his battalion, and after him Lannoy with the Neapolitan soldiers. Then came five hundred light horse under Castrioto, then the lanz-knechts under Von Frundsberg, and lastly the reiters and Burgundian cavalry. The rear-guard was commanded by Bourbon. The whole of the army was in excellent condition, and though the men were unpaid, they were content with the promises of plunder held out to them by their leaders. Under such circumstances, however, it was incumbent that a battle should take place with as little delay as possible, and on this point both Bourbon and Pescara were agreed.

Instead of marching direct upon Pavia, the Imperial generals proceeded towards Milan, as if designing to attack that city, hoping by the device to draw François from his intrenched camp, but the king was either too well informed of their design or too wary, for he would not quit his position.

Finding he did not move, they altered their course and gradually approached Pavia, and as they drew near to the French camp frequent skirmishes took place between troops of cavalry on either side, in which, owing to the address and daring of Pescara and Del Vasto, the advantage generally remained with the Imperialists.

By the king's command Bonnivet had been despatched with four hundred light horse to watch the movements of the enemy, and while thus employed in the neighbourhood of Belgiojoso, he was surprised by Pescara, and after a sharp skirmish compelled to retreat.

On learning that the enemy were now close at hand, the king quitted his quarters at San Lanfranco, and removed to the neighbourhood of the Certosa, a magnificent convent situated at the northern extremity of the park of Mirabello.

By this time the whole of the Imperial army had come up, and was encamped upon a plain, between two canals, on the east of Pavia, about a league from the walls of the city, and about half a league from the advanced guard of the French army. The hostile camps were separated by the Vernacula, a small but deep river, with steep banks. The spot chosen for their camp by the Imperialists was protected by a rising ground from the French artillery, while the Vernacula served them as a trench.

After carefully studying the position of the French army, Pescara became convinced that it would be impossible to force them in their intrenchments, and as all attempts to draw them forth had proved ineffectual, some new expedient must be adopted. At last he hit upon a plan, which he proposed to Bourbon.

“Since all other means have failed,” he said, “I propose to proceed in this manner. The attack must be made to-night. My design is to make a breach in the walls of the park of Mirabello sufficiently large to allow the passage of our whole army. This can be readily accomplished in a few hours, and without artillery, if we are undiscovered. The walls can be battered down by rams and other engines, and while the operations are going on, false attacks must be made at two or three different points of the French camp, so as to distract their attention. Once within the park, we shall have nothing between us and the king, whose quarters are now near the Certosa. If we cannot compel him to give us battle, we can at least succour Pavia.”

“I like the plan, and doubt not it will succeed,” remarked Bourbon. “But De Leyva must be informed of it, that he may hold himself in readiness to sally forth with the garrison.”

“I will engage to take a message to him,” said Pomperant, who was standing by.

“Tell him go make ready to-night,” said Pescara; “and when he hears cannon fired in the park to come forth with his men.”

“It shall be done,” replied Pomperant. “It is well you have resolved to execute your plan without delay, for Pavia is reduced almost to the last extremity.”

About an hour before midnight Pescara put his battalion in motion, and after making a wide circuit, so as to avoid the French pickets, he approached the farther side of the park of Mirabello. Del Vasto followed. Next came Castrioto, with his squadron of five hundred light horse. Then came Lannoy, with his Neapolitan soldiers. Then the Burgundian cavalry under the Comte de Salms; and lastly Bourbon, Von Frundsberg, and Marx Sittich d'Ems, with the German lanz-knechts and reiters. The night was so dark, and the movement so noiselessly executed, that no suspicion was entertained by the French.

As the mighty host thus silently collected upon a plain on the north side of the park, they were concealed from the French sentinels by a thick intervening wood. From this plain the dark outline of Pavia, with its numerous lofty towers, its Duomo and castle, could be discerned, and the sounds that disturbed the silence of the night proclaimed that the garrison were astir.

No sooner did Pescara reach that portion of the walls which he had selected for his purpose, than a large body of pioneers set to work to batter them down with rams, huge beams of wood, and other engines. But the walls had been very solidly built by Gian Galeazzo Visconti, and offered a more obstinate resistance than had been expected. Dawn was at hand before a sufficiently large breach could be made.

While this operation was proceeding, two false attacks, as preconcerted, had been made upon the French camp, accompanied by a constant discharge of artillery; but in spite of this precaution the plan was discovered, and communicated to François.

As soon as the breach was practicable, the Marquis del Vasto, in obedience to Pescara's injunctions, dashed into the park with his battalion, and hastened to the Castle of Mirabello, which he attacked and took without difficulty, dispersing the troops by whom it was garrisoned.

So far success had crowned the attempt. But a sudden check was now experienced.
