The behaviour of Louis at this juncture is contemptible beyond words, obeying as it does the maxim of that age, which had it that no inconvenient engagement should be observed if there was opportunity for breaking it.
Following this detestable maxim, Louis XII had actually gone the length of never paying to Charlotte d'Albret the dot of 100,000 livres Tournois, to which he had engaged himself by written contract.

When Cesare, in prison at Medina and in straits for money, had solicited payment through his brother-in-law of Navarre, his claim had been contemptuously disregarded.
But there was worse to follow.

Louis now answered Cesare's request for leave to come to France by a letter (quoted in full by M.Yriarte from the Archives des Basses Pyrenees) in which his Very Christian Majesty announces that the duchy of Valentinois and the County of Dyois have been restored to the crown of France, as also the lordship of Issoudun.
And then follows the pretext, of whose basely paltry quality you shall judge for yourselves.

It runs: "After the decease of the late Pope Alexander, when our people and our army were seeking the recovery of the kingdom of Naples, he [Cesare] went over to the side of our enemies, serving, favouring, and assisting them at arms and otherwise against ourselves and our said people and army, which resulted to us in great and irrecoverable loss." The climax is in the deliberate falsehood contained in the closing words.

Poor Cesare, who had served France at her call--in spite of what was rumoured of his intentions--as long as he had a man-at-arms to follow him, had gone to Naples only in the hour of his extreme need.
True, he had gone to offer himself to Spain as a condottiero when naught else was left to him; but he took no army with him--he went alone, a servant, not an ally, as that false letter pretends.
