Battle of Castillon
In 1446, like his father before him, John became a Knight in the Order of the Garter. He was active in the defence and subsequent recovery of the city of Bordeaux. Then on 17 July 1453 he and John Talbot, 1st Earl of Shrewsbury, fought the French forces at the Battle of Castillon. Talbot and a son were killed and Jean de Foix was taken prisoner.
