Arnaud Guillaume (also Arnault Guilhem), Seigneur de Barbazan, (1360 in Barbazan-Dessus, Hautes-Pyrénées, France – 1431, Vaudoncourt, Vosges, France) was a counsellor and butler to Charles VII of France and later a general during the Hundred Years' War who earned for himself the name of the Irreproachable Knight.
Duke René had support from his brother, the French king Charles VII, who sent an army of 4000 cavalry and 6000 infantry under the command of the old soldier Arnaud Guillaume de Barbazan.
John the Fearless was killed on the town's bridge in September, 1419 by Tanneguy du Chastel and the sire de Barbazan, during an interview with the dauphin (who became in 1422 Charles VII).
