To the caprice of Louise of Savoy were due the disasters and defeats of the French army during the period of her power; by frequently displacing someone whose actions did not coincide with her plans, and elevating some favorite who had avowed his willingness to serve her, she kept military affairs in a state of confusion.
Many wanton acts are attributed to her: she appropriated forty thousand crowns allowed to Governor Lautrec of Milan for the payment of his soldiers, and caused the execution of Samblancay, superintendent of finances, who had been so unfortunate as to incur her displeasure. It was Charles of Bourbon, who, with Marshal Lautrec, investigated the episode of the forty thousand crowns and exposed the treachery and perfidy of the mother of his king.
Finding that Bourbon intended to persist in his resistance to her advances, Louise decided upon drastic measures of retaliation. With the assistance of her chancellor (and tool), Duprat, she succeeded in having withheld the salaries which were due to Bourbon because of the offices held by him. As he took no notice of these deprivations, she next proceeded to divest him of his estates by laying claim to them for herself; she then proposed to Bourbon that, by accepting her hand in marriage, he might settle the matter happily. The object of her numerous schemes not only rejected this offer with contempt, but added insult to injury by remarking: "I will never marry a woman devoid of modesty." At this rebuff, Louise was incensed beyond measure, and when Queen Claude suggested Bourbon's marriage to her sister, Mme. Renée de France (a union to which Charles would have consented gladly), the queen-mother managed to induce Francis I. to refuse his consent.
After the death of Anne of Beaujeu, mother-in-law of Charles of Bourbon, her estates were seized by the king and transferred to Louise while the claim was under consideration by Parliament. When the judges, after an examination of the records of the Bourbon estate, remonstrated with Chancellor Duprat against the illegal transfer, he had them put into prison. This rigorous act, which was by order of Louise, weakened the courage of the court; when the time arrived for a final decision, the judges declared themselves incompetent to decide, and in order to rid themselves of responsibility referred the matter to the king's council. This great lawsuit, which was continued for a long time, eventually forced Charles of Bourbon to flee from France. Having sworn allegiance to Charles V. of Spain and Henry VIII. of England against Francis I., he was made lieutenant-general of the imperial armies.
