Gaucher V de Châtillon

Gaucher V de Châtillon (c. 1249–1329), count of Porcien, was named constable of Champagne by Philip III in 1284 and helped free Charles II of Naples from Aragonese captivity. In 1291 he drove the Count of Bar's army out of Champagne.

He fought in Flanders in 1302, surviving the defeat at Courtrai, after which Philip IV made him constable of France. In 1316 he backed Philip of Poitiers' regency and moved that women be barred from the crown. Still campaigning at eighty, he fought at Cassel in 1328 and died the next year.
