This personage was born in 1549, and was the eldest son of Jacques de Clermont d'Amboise, seigneur de Bussy et de Saxe-Fontaine, by his first wife, Catherine de Beauvais. He followed the career of arms, and in 1568 we hear of him as a commandant of a company. He was in Paris during the massacre of St. Bartholomew, and took advantage of it to settle a private feud. He had had a prolonged lawsuit with his cousin Antoine de Clermont, a prominent Huguenot, and follower of the King of Navarre. While his rival was fleeing for safety he had the misfortune to fall into the hands of Bussy, who dispatched him then and there. He afterwards distinguished himself in various operations against the Huguenots, and by his bravery and accomplishments won the favour of the Duke of Anjou, who, after the accession of Henry III in 1575, was heir to the throne. The Duke in this year appointed him his _couronell_, and henceforward he passed into his service. In 1576, as a reward for negotiating "_la paix de Monsieur_" with the Huguenots, the Duke received the territories of Anjou, Touraine, and Berry, and at once appointed Bussy governor of Anjou. In November the new governor arrived at Angers, the capital of the Duchy, and was welcomed by the citizens; but the disorders and exactions of his troops soon aroused the anger of the populace, and the King had to interfere in their behalf, though for a time Bussy set his injunctions at defiance. At last he retired from the city, and rejoined the Duke, in close intercourse with whom he remained during the following years, accompanying him finally on his unsuccessful expedition to the Low Countries in the summer of 1578. On Anjou's return to court in January, 1579, Bussy, who seems to have alienated his patron by his presumptuous behaviour, did not go with him, but took up his residence again in the territory of Anjou. He was less occupied, however, with his official duties than with his criminal passion for Françoise de Maridort, wife of the Comte de Monsoreau, who had been appointed _grand-veneur_ to the Duke. The favorite mansion of the Comte was at La Coutancière, and it was here that Bussy ardently pursued his intrigue with the Countess. But a jocular letter on the subject, which he sent to the Duke of Anjou, was shown, according to the historian, De Thou, by the Duke to the King, who, in his turn, passed it on to Montsoreau. The latter thereupon forced his wife to make a treacherous assignation with Bussy at the château on the night of the 18th of August, and on his appearance, with his companion in pleasure, Claude Colasseau, they were both assassinated by the retainers of the infuriated husband.
