Tanguy du Chastel

Tanneguy III du Chastel (or Tanguy du Châtel) (1369–1449) was a French military leader of the Hundred Years' War.

In 1415, he was provost of Paris, charged with keeping order in the city. During the civil war between the Armagnacs and Burgundians, he was one of the leaders of the Armagnac faction under Bernard VII, Count of Armagnac, constable of France. He opposed the partisans of the duke of Burgundy in their attempts to capture Paris. Alain de Coëtivy, bishop of Avignon, was a nephew of his.

He was a favourite of Charles the Dauphin (later Charles VII) whom he saved by taking him out of Paris to Melun at the time of the invasion of Paris by the Burgundians led by Jean de Villiers de l'Isle-Adam during the night of 28-29 May 1418. With Jean Louvet, another of Charles VII's favourites, he was one of the main instigators of the assassination of John the Fearless by some Armagnac men-at-arms during his meeting with Charles on the bridge at Montereau on 10 September 1419.

From 1425, his influence waned as Arthur de Richemont's waxed. Also, in 1429, he used all his effort to convince the Dauphin to receive and welcome Joan of Arc - in effect, several of Charles VII's counsellors supported the principle of a rapprochement with Burgundy in order to present a united front against England, which could not have been achieved without du Chastel's efforts.
