This treaty was signed at the Vatican on the 23rd, between Borgia and Bentivogli, to guarantee the States of both.
The King of France, the Signory of Florence, and the Duke of Ferrara guaranteed the alliance.
Inter alia, it was agreed between them that Bologna should supply Cesare with 100 lances and 200 light horse for one or two enterprises within the year, and that the condotta of 100 lances which Cesare held from Bologna by the last treaty should be renewed.

The terms of the treaty were to be kept utterly secret for the next three months, so that the affairs of Urbino and Camerino should not be prejudiced by their publication.
The result was instantaneous.

On November 27 Paolo Orsini was back at Imola with the other treaty, which bore now the signatures of all the confederates.

Vitelli, finding himself isolated, had swallowed his chagrin in the matter of Florence, and his scruples in the matter of Urbino, abandoning the unfortunate Guidobaldo to his fate.

This came swiftly.
