Du Guesclin
BERTRAND (dügā-klan), Constable of France; born about 1314. Mainly to him must be attributed the expulsion of the English from Normandy, Guienne, and Poitou.
He was captured by Chandos at the battle of Auray in 1364, and ransomed for 100,000 francs. While serving in Spain against Peter the Cruel he was made prisoner by the English Black Prince; but was soon liberated. For his services in Spain he was made Constable of Castile, Count of Trastamare, and Duke of Molinas; and in 1370 he was made Constable of France. He died in 1380.
