While these events were proceeding in Tuscany the Count Sforza, having become leader of the Milanese forces, strenuously endeavored to secure the friendship of Francesco Piccinino, who was also in their service, that he might support him in his enterprises, or be less disposed to do him injury. He then took the field with his army, upon which the people of Pavia, conscious of their inability to resist him, and unwilling to obey the Milanese, offered to submit themselves to his authority, on condition that he should not subject them to the power of Milan. The count desired the possession of Pavia, and considered the circumstance a happy omen, as it would enable him to give a color to his designs. He was not restrained from treachery either by fear or shame; for great men consider failure disgraceful,--a fraudulent success the contrary. But he was apprehensive that his possession of the city would excite the animosity of the Milanese, and perhaps induce them to throw themselves under the power of the Venetians. If he refused to accept the offer, he would have occasion to fear the duke of Savoy, to whom many citizens were inclined to submit themselves; and either alternative would deprive him of the sovereignty of Lombardy. Concluding there was less danger in taking possession of the city than in allowing another to have it, he determined to accept the proposal of the people of Pavia, trusting he would be able to satisfy the Milanese, to whom he pointed out the danger they must have incurred had he not complied with it; for her citizens would have surrendered themselves to the Venetians or to the duke of Savoy; so that in either case they would have been deprived of the government, and therefore they ought to be more willing to have himself as their neighbor and friend, than a hostile power such as either of the others, and their enemy. The Milanese were upon this occasion greatly perplexed, imagining they had discovered the count's ambition, and the end he had in view; but they thought it desirable to conceal their fears, for they did not know, if the count were to desert them, to whom they could have recourse except the Venetians, whose pride and tyranny they naturally dreaded. They therefore resolved not to break with the count, but by his assistance remedy the evils with which they were threatened, hoping that when freed from them they might rescue themselves from him also; for at that time they were assailed not only by the Venetians but by the Genoese and the duke of Savoy, in the name of Charles of Orleans, the son of a sister of Filippo, but whom the count easily vanquished. Thus their only remaining enemies were the Venetians, who, with a powerful army, determined to occupy their territories, and had already taken possession of Lodi and Piacenza, before which latter place the count encamped; and, after a long siege, took and pillaged the city. Winter being set in, he led his forces into quarters, and then withdrew to Cremona, where, during the cold season, he remained in repose with his wife.
In the spring, the Venetian and Milanese armies again took the field.
It was the design of the Milanese, first to recover Lodi and then to come to terms with the Venetians; for the expenses of the war had become very great, and they were doubtful of their general's sincerity, so that they were anxious alike for the repose of peace, and for security against the count. They therefore resolved that the army should march to the siege of Carravaggio, hoping that Lodi would surrender, on that fortress being wrested from the enemy's hands. The count obeyed, though he would have preferred crossing the Adda and attacking the Brescian territory. Having encamped before Caravaggio, he so strongly entrenched himself, that if the enemy attempted to relieve the place, they would have to attack him at a great disadvantage. The Venetian army, led by Micheletto, approached within two bowshots of the enemy's camp, and many skirmishes ensued. The count continued to press the fortress, and reduced it to the very last extremity, which greatly distressed the Venetians, since they knew the loss of it would involve the total failure of their expedition. Very different views were entertained by their military officers respecting the best mode of relieving the place, but they saw no course open except to attack the enemy in his trenches, in spite of all obstacles.
The castle was, however, considered of such paramount importance, that the Venetian senate, though naturally timid, and averse to all hazardous undertakings, chose rather to risk everything than allow it to fall into the hands of the enemy.
