The Brilliant General Who Betrayed His King to Command the Enemy's Army

History · Published 3 October 2026 Swipe more like this →

In short: Louis II de Bourbon, known as the Great Condé, was a military prodigy who secured France's greatest victory in a century at Rocroi. Yet, his limitless pride and arrogance led him to launch an open rebellion against his own crown, ultimately defecting to lead Spanish forces against his native country.

Born in 1621, the young duc d’Enghien received a rigorous education before proving his tactical genius at the Battle of Rocroi in 1643. This victory over the Spanish, achieved through his personal command, cemented his reputation as one of the era's greatest generals. Alongside the marshal de Turenne, he secured further triumphs at Freiburg, Mainz, and Nördlingen, establishing himself as a central figure in the House of Bourbon.

His meteoric rise, however, collided with the political instability of the Fronde, a series of aristocratic uprisings. Following his father's death in 1646, Condé inherited vast wealth and influence, which deeply unsettled Cardinal Mazarin. After a period of imprisonment, Condé’s resentment boiled over into open rebellion in 1651. He allied with Spain, the very nation he had previously defeated, and eventually became their generalissimo, leading troops against the French royal army until his defeat at the Battle of the Dunes in 1658.

Following the 1659 Peace of the Pyrenees, Condé was pardoned by Louis XIV. He returned to France, comporting himself as a loyal servant, though the king remained cautious, long denying him military command. Eventually restored to favor, he led successful campaigns in the Franche-Comté and the Netherlands in the 1670s. Despite his military brilliance, he remained a man of unrestrained temper and pride, spending his final years in quiet retirement at Chantilly, surrounded by artists and writers until his death in 1686.
