DUNOIS, JEAN, COUNT OF (1403-1468), commonly called the "Bastard of Orleans," a celebrated French commander, was the natural son of the duke of Orleans (brother of Charles VI.) and Mariette d'Enghien, Madame de Canry. His earliest feat of arms was the surprise and rout in 1427 of the English, who were besieg ing Montargis—the first successful blow against the English power in France following a long series of French defeats. In 1423 he defended Orleans with the greatest spirit, and enabled the place to hold out until the arrival of Joan of Arc, when he shared with her the honour of defeating the enemy there in 1429. He then accom panied Joan to Reims and shared in the victory of Patay. After her death he raised the siege of Chartres and of Lagny (1432) and engaged in a series of successful campaigns which ended in his tri umphal entry into Paris (April 13, 1436). He gradually drove the English northward; in 1450 he reconquered northern France, and in 1451 attacked the English in Guienne, taking among other towns Bordeaux and Bayonne. In 1465 he joined the league of revolted princes, but, assuming the function of negotiator, he was after a time reinstated in his offices. He died on Nov. 24, 1468.
