Jean III de Grailly (aka. John De Grailly, died 7 September 1376), Captal de Buch, , was a Gascon nobleman and a military leader in the Hundred Years' War, who was praised by the chronicler Jean Froissart as an ideal of chivalry. Biography He was the son of Jean II de Grailly, Captal de Buch, Vicomte de Benauges, and of Blanch de Foix, a cousin of the counts of Foix. Attached to the English side in the conflict, he was made Count of Bigorre by Edward III of England, and was also a founder and the fourth Knight of the Garter in 1348. He played a decisive role as a cavalry leader under Edward, the Black Prince in the Battle of Poitiers (1356), with de Buch leading a flanking move against the French that resulted in the capture of the king of France (John II), as well as many of his nobles. John was taken to London by the Black Prince and held to ransom. In 1364, he commanded the forces of Charles II of Navarre in Normandy, where he was defeated and captured by Bertrand du Guesclin at Cocherel. After his release the following year, he defected to the French side and was made lord of Nemours by Charles V of France. However, he soon re-established his loyalty to the English, and in 1367 he went to Spain with the Black Prince, fighting at the Battle of Nájera. Here he again faced Bertrand du Guesclin, but this time it was du Guesclin who was captured, and the Captal was put in charge of the prisoner. He was rewarded for his service by being made the Constable of Aquitaine in 1371. Again fighting for the English, he commanded an English relief force when the French attacked La Rochelle in 1372. While attempting to lift the siege of Soubise, his force was surprised by a French force led by Owain Lawgoch, a Welsh soldier of fortune in the French service. The Captal and Sir Thomas Percy, seneschal of Poitou, were captured. The Captal spent the remainder of his life as a prisoner at the Temple in Paris, because Charles V believed him too dangerous to ransom back to the English. Froissart gives an account of the Captal de Buch's chivalry and courage at the time of the peasant uprising in 1358 called the Jacquerie (see link). Jean de Grailly was a
