In spite of the truce he had but lately concluded with Charles the Rash, the prudent Louis did not cease to keep an attentive watch upon him, and to reap advantage, against him, from the leisure secured to the King of France by his peace with the King of England and the Duke of Brittany. A late occurrence had still further strengthened his position: his brother Charles, who became Duke of Guienne, in 1469, after the treaty of Peronne, had died on the 24th of May, 1472. There were sinister rumors abroad touching his death. Louis was suspected, and even accused to the Duke of Brittany, an intimate friend of the deceased prince, of having poisoned his brother. He caused an inquiry to be instituted into the matter; but the inquiry itself was accused of being incomplete and inconclusive. “King Louis did not, possibly, cause his brother’s death,” says M. de Barante, “but nobody thought him incapable of it.” The will which Prince Charles had dictated a little before his death increased the horror inspired by such a suspicion. He manifested in it a feeling of affection and confidence towards the king his brother; he requested him to treat his servants kindly; “and if in any way,” he added, “we have ever offended our right dread and right well-beloved brother, we do beg him to be pleased to forgive us; since, for our part, if ever in any matter he hath offended us, we do affectionately pray the Divine Majesty to forgive him, and with good courage and good will do we on our part forgive him.” The Duke of Guienne at the same time appointed the king executor of his will. If we acknowledge, however, that Louis was not incapable of such a crime, it must be admitted that there is no trust-worthy proof of his guilt. At any rate his brother’s death had important results for him. Not only did it set him free from all fresh embarrassment in that direction, but it also restored to him the beautiful province of Guienne, and many a royal client. He treated the friends of Prince Charles, whether they had or had not been heretofore his own, with marked attention. He re-established at Bordeaux the parliament he had removed to Poitiers; he pardoned the towns of Pdzenas and Montignac for some late seditions; and, lastly, he took advantage of this incident to pacify and satisfy this portion of the kingdom. Of the great feudal chieftains who, in 1464, had formed against him the League of the common weal, the Duke of Burgundy was the only one left on the scene, and in a condition to put him in peril.
