Jacques de Chabannes

The elder brother of Antoine de Chabannes, he is most notable for his significant role at the Battle of Castillon in 1453.

In 1440 he participated in the feudal revolt against Charles VII known as the Praguerie and subsequently lost his post as Seneschal of Toulouse, which he had been given in 1438, but was back in royal favor by the mid-1440s.

In 1451 the king awarded him the lordship of Curton and its dependencies, southwest of Bordeaux, which he had confiscated from Louis II de Beaumont-Bressuire.

On 17 July 1453 he was instrumental in the decisive French victory at the Battle of Castillon, which effectively marked the end of the Hundred Years' War.

His younger brother Antoine de Chabannes, who in the meantime had become one of France's prominent military leaders, inherited the command of his company of soldiers.
