Jean was born as the illegitimate son of Louis I, Duke of Orleans, gaining the nickname 'Bastard of Orleans.' His birth circumstances would shape his lifelong quest for legitimacy and honor.

Louis I, Duke of Orleans, was assassinated by the Burgundian faction under John the Fearless. This event sparked the civil war between Armagnacs and Burgundians that would define Dunois's early life.

Dunois entered military service during France's darkest hour. The Treaty of Troyes had disinherited the Dauphin, and English forces controlled most of northern France.

Dunois was appointed captain of the formidable fortress of Château-Gaillard on the Seine, demonstrating early trust in his military abilities.

Charles VII created Dunois Count of Dunois, formally recognizing his noble status and consolidating his position among the French nobility despite his illegitimate birth.

Dunois met Joan of Arc at Blois, beginning one of history's most legendary military partnerships. Initially skeptical, he quickly recognized her extraordinary abilities and divine mission.

Dunois and Joan of Arc led the successful relief of Orleans, breaking the English siege. This victory marked the turning point of the Hundred Years' War and the beginning of French recovery.

Dunois fought alongside Joan in the Loire Campaign, winning decisive victories at Jargeau, Meung, and Beaugency, clearing the path to Reims for Charles VII's coronation.

After Joan of Arc's capture at Compiègne, Dunois continued the fight, maintaining French military momentum and proving that the revival was more than one person's doing.

The Treaty of Arras reconciled France and Burgundy, ending the civil war that had plagued France for decades. Dunois had worked toward this diplomatic triumph alongside the military one.

Dunois helped suppress the Praguerie, a rebellion of nobles including the Dauphin against Charles VII. His loyalty to the crown further cemented his position as the king's most trusted commander.

Charles VII appointed Dunois Lieutenant-General of Normandy, tasking him with leading the reconquest of this crucial province from English control.

Dunois achieved a decisive victory at the Battle of Formigny, destroying the main English army in Normandy. This triumph effectively ended English rule in the province.

Dunois commanded the conquest of Guyenne, liberating Bordeaux and the southwest from three centuries of English rule. Only Calais remained in English hands.

Dunois died at his castle of L'Haÿ-les-Roses, honored as one of France's greatest military commanders. The 'Bastard of Orleans' had become the hero of French reconquest.
