The League found they must no longer delay rendering him efficient assistance, and ordered the duke of Calabria to march to Ferrara with his forces and those of the pope, the Florentine troops also moving in the same direction. In order to direct the operations of the war with greater efficiency, the League assembled a diet at Cremona, which was attended by the pope's legate, the Count Girolamo, the duke of Calabria, the Signor Lodovico Sforza, and Lorenzo de' Medici, with many other Italian princes; and when the measures to be adopted were fully discussed, having decided that the best way of relieving Ferrara would be to effect a division of the enemy's forces, the League desired Lodovico to attack the Venetians on the side of Milan, but this he declined, for fear of bringing a war upon the duke's territories, which it would be difficult to quell. It was therefore resolved to proceed with the united forces of the League to Ferrara, and having assembled four thousand cavalry and eight thousand infantry, they went in pursuit of the Venetians, whose force amounted to two thousand two hundred men at arms, and six thousand foot. They first attacked the Venetian flotilla, then lying upon the river Po, which they routed with the loss of above two hundred vessels, and took prisoner Antonio Justiniano, the purveyor of the fleet. The Venetians, finding all Italy united against them, endeavored to support their reputation by engaging in their service the duke of Lorraine, who joined them with two hundred men at arms: and having suffered so great a destruction of their fleet, they sent him, with part of their army, to keep their enemies at bay, and Roberto da San Severino to cross the Adda with the remainder, and proceed to Milan, where they were to raise the cry of "The duke and the Lady Bona," his mother; hoping by this means to give a new aspect to affairs there, believing that Lodovico and his government were generally unpopular. This attack at first created great consternation, and roused the citizens in arms;but eventually produced consequences unfavorable to the designs of the Venetians; for Lodovico was now desirous to undertake what he had refused to do at the entreaty of his allies. Leaving the marquis of Ferrara to the defense of his own territories, he, with four thousand horse and two thousand foot, and joined by the duke of Calabria with twelve thousand horse and five thousand foot, entered the territory of Bergamo, then Brescia, next that of Verona, and, in defiance of the Venetians, plundered the whole country; for it was with the greatest difficulty that Roberto and his forces could save the cities themselves. In the meantime, the marquis of Ferrara had recovered a great part of his territories; for the duke of Lorraine, by whom he was attacked, having only at his command two thousand horse and one thousand foot, could not withstand him. Hence, during the whole of 1483, the affairs of the League were prosperous.
The winter having passed quietly over, the armies again took the field. To produce the greater impression upon the enemy, the League united their whole force, and would easily have deprived the Venetians of all they possessed in Lombardy, if the war had been conducted in the same manner as during the preceding year; for by the departure of the duke of Lorraine, whose term of service had expired, they were reduced to six thousand horse and five thousand foot, while the allies had thirteen thousand horse and five thousand foot at their disposal.
But, as is often the case where several of equal authority are joined in command, their want of unity decided the victory to their enemies.
Federigo, marquis of Mantua, whose influence kept the duke of Calabria and Lodovico Sforza within bounds, being dead, differences arose between them which soon became jealousies. Giovan Galeazzo, duke of Milan, was now of an age to take the government on himself, and had married the daughter of the duke of Calabria, who wished his son-in-law to exercise the government and not Lodovico; the latter, being aware of the duke's design, studied to prevent him from effecting it.
The position of Lodovico being known to the Venetians, they thought they could make it available for their own interests; and hoped, as they had often before done, to recover in peace all they had lost by war; and having secretly entered into treaty with Lodovico, the terms were concluded in August, 1484. When this became known to the rest of the allies, they were greatly dissatisfied, principally because they found that the places won from the Venetians were to be restored; that they were allowed to keep Rovigo and the Polesine, which they had taken from the marquis of Ferrara, and besides this retain all the pre-eminence and authority over Ferrara itself which they had formerly possessed. Thus it was evident to everyone, they had been engaged in a war which had cost vast sums of money, during the progress of which they had acquired honor, and which was concluded with disgrace; for the places wrested from the enemy were restored without themselves recovering those they had lost. They were, however, compelled to ratify the treaty, on account of the unsatisfactory state of their finances, and because the faults and ambition of others had rendered them unwilling to put their fortunes to further proof.
