The marriage, arranged on condition that the pope should pay 200,000 ducats dowry to the bride, and should make her brother cardinal, was celebrated on the 10th of May; and on the Whitsunday following the Duke of Valentois received the order of St.Michael, an order founded by Louis XI, and esteemed at this period as the highest in the gift of the kings of France.

The news of this marriage, which made an alliance with Louis XII certain, was received with great joy by the pope, who at once gave orders far bonfires and illuminations all over the town.
Louis XII was not only grateful to the pope for dissolving his marriage with Jeanne of France and authorizing his union with Anne of Brittany, but he considered it indispensable to his designs in Italy to have the pope as his ally.

So he promised the Duke of Valentinois to put three hundred lances at his disposal, as soon as he had made an entry into Milan, to be used to further his own private interests, and against whomsoever he pleased except only the allies of France.

The conquest of Milan should be undertaken so soon as Louis felt assured of the support of the Venetians, or at least of their neutrality, and he had sent them ambassadors authorised to promise in his name the restoration of Cremona and Ghiera d'Adda when he had completed the conquest of Lombardy..
