He himself tells us that his two ambitions were to become "honnĂŞte homme" and to distinguish himself in arms, but luck was against him.
In 1641 he was sent to the Bastille by Richelieu for some months as a punishment for neglect of his duties in his pursuit of gallantry.
In 1643 he married a cousin, Gabrielle de Toulongeon, and for a short time he left the army.
He fought with some distinction both in the civil war and on foreign service and, buying the commission of mestre de camp in 1655, he went on to serve under Turenne in Flanders.
He served there in several campaigns and distinguished himself at the Battle of the Dunes (1658) and elsewhere; but he did not get on well with his general, and his quarrelsome disposition, his overweening vanity and his habit of composing libellous chansons made him eventually the enemy of most persons of position both in the army and at court.
In the year 1659 he fell into disgrace for having taken part in an orgy at Roissy near Paris during Holy Week, which caused great scandal.
Bussy was ordered to retire to his estates at Château de Bussy-Rabutin, and beguiled his enforced leisure by composing his famous Histoire amoureuse des Gaules (written in 1660) for the amusement of his sick mistress, Madame de Montglas.
This book, a series of portraits and accounts of the intrigues of the chief ladies of the court, witty enough, but still more ill-natured, circulated freely in manuscript and had numerous spurious sequels.
Although Bussy denied the charges, blaming Madame de la Baume (Catherine de Bonne, comtesse de Tallard, died 1692), a former intimate of his, it was said that he had not spared the reputations of members of the royal family, including Madame and the Queen Mother.
In a letter of apology and explanation to the king Bussy claimed that a false friend who had asked to borrow it briefly (Madame de la Baume) had copied it and altered it without his knowledge.
The king, angry at the report, was momentarily appeased when Bussy showed him the original manuscript to disprove the scandal, but a closed-door meeting (most likely with Madame de la Baume) sealed Bussy's fate.He was sent to the Bastille on 17 April 1665, where he remained for more than a year, and he was only liberated on condition of retiring to his estates, where he lived in exile for seventeen years.
Bussy felt the disgrace keenly, but the enforced close of his military career was still more bitter.
The literary and historical student, therefore, owes Bussy some thanks.
Bussy wrote other things, of which the most important, his Genealogy of the Rabutin Family, remained in manuscript till 1867, while his Considerations sur la guerre was first published in Dresden in 1746.
He also wrote a series of biographies for the use of his children, in which his own life serves a moral purpose.
