Descended from the illustrious house of Avalos of Toledo, Pescara inherited all the pride and arrogance of his ancestors. Though still young, for at the period of which we treat he was only thirty-four, he had passed a long life in arms. He was taken prisoner by the French at the battle of Ravenna, and on his release returned to the army, and was again worsted at Vicenza, but covered himself with glory by driving Lautrec from Milan in 1521--only two years before our history. This achievement won him the greater renown, since the cautious Prospero Colonna declined to attempt the enterprise. In the succeeding campaign the valiant Spanish leader distinguished himself by several brilliant feats of arms. He succoured Pavia when besieged by the French--helped to win the battle of Bicocca--took Lodi and Pizzighettone--and compelled Lescun to surrender Cremona. He subsequently besieged and took Genoa, delivering the city to pillage. These exploits caused him to be regarded as one of the great captains of the age. Fearless, energetic, rash, Pescara derided danger, and would undertake any enterprise, however hazardous. His constant disagreements, however, with Colonna rendered his position in the confederate army unsupportable, and he resigned his command and withdrew to Naples, where he remained till Lannoy was called upon to fill Colonna's post. In obedience to the Emperor's orders, Pescara then returned to Milan to resume his command of the Spanish forces, his place having been temporarily filled by Captain Alarcon. The haughty marquis was perfectly content to serve under Lannoy; but when he heard of Bourbon's appointment as lieutenant-general of the confederate army, and representative of the Emperor, his jealousy was immediately excited. Another Spanish general of distinction, of whom we shall have occasion hereafter more fully to speak, was Don Antonio de Leyva. At this juncture he occupied Pavia with a force of six thousand infantry and a thousand horse, and had so strongly fortified the city that he conceived it impregnable. De Leyva had risen to his present eminence after a long and brilliant career. The command of the Italian division, which consisted of Lombards, Florentines, Romans, Modenese, Lucchese, and Neapolitan soldiers, was entrusted to Francisco Sforza, Duke of Milan. Associated with Sforza was the Duke of Urbino, general of the Venetian forces who had recently joined the confederates. IV. HOW THE DUKE DE BOURBON ENTERED MILAN.
