while fortune, would esteem him more than if he were in adversity; that the duke was induced to promise him his daughter by the fear he entertained of him; that what necessity occasions to be promised, it also causes to be performed; and it was therefore desirable to keep the duke in that necessity, which could be done without supporting the power of the Venetians.  Therefore he might perceive, that if the Venetians were compelled to abandon their inland territories, he would not only lose the advantages derivable from them, but also those to be obtained from such as feared them; and that if he considered well the powers of Italy, he would see that some were poor, and others hostile; that the Florentines alone were not, as he had often said, sufficient for his support; so that on every account it was best to keep the Venetians powerful by land.  These arguments, conjoined with the hatred which the count had conceived against Filippo, by supposing himself duped with regard to the promised alliance, induced him to consent to a new treaty; but still he would not consent to cross the Po.  The agreement was concluded in February, 1438; the Venetians agreeing to pay two-thirds of the expense of the war, the Florentines one-third, and each engaging to defend the states which the count possessed in La Marca.  Nor were these the only forces of the league, for the lord of Faenza, the sons of Pandolfo Malatesti da Rimino and Pietro Giampagolo Orsini also joined them.  They endeavored, by very liberal offers, to gain over the marquis of Mantua, but could not prevail against the friendship and stipend of the duke; and the lord of Faenza, after having entered into compact with the league, being tempted by more advantageous terms, went over to him.  This made them despair of being able to effect an early settlement of the troubles of Romagna.

The affairs of Lombardy were in this condition:  Brescia was so closely besieged by the duke’s forces, that constant apprehensions were entertained of her being compelled by famine to a surrender; while Verona was so pressed, that a similar fate was expected to await her, and if one of these cities were lost, all the other preparations for the war might be considered useless, and the expenses already incurred as completely wasted.  For this there was no remedy, but to send the count into Lombardy; and to this measure three obstacles presented themselves.  The first was, to induce him to cross the Po, and prosecute the war in whatever locality might be found most advisable; the second, that the count being at a distance, the Florentines would be left almost at the mercy of the duke, who, issuing from any of his fortresses, might with part of his troops keep the count at bay, and with the rest introduce into Tuscany the Florentine exiles, whom the existing government already dreaded; the third was, to determine what route the count should take to arrive safely in the Paduan territory, and join the Venetian forces.  Of these three difficulties,
