John III of Montfaucon

John III of Montfaucon (c. 1333–1372) was lord of Orbe and Échallens in the Vaud, son of Girard de Montfaucon and Jacquette of Grandson. In 1354 he sided with his uncle Henry, Count of Montbéliard, in a feud with Louis of Neuchâtel over Jeanne's inheritance; the war spread through the mountains of the Doubs until Philip of Burgundy stepped in.

In 1366 he followed Amadeus VI of Savoy on the expedition to rescue the Byzantine emperor John V Palaiologos. Six years later he rode with Amadeus again, to help Pope Gregory XI against the Visconti, and died at the Battle of Asti in September 1372.

His body was carried on a shield to the count's lodging, to the displeasure of all the lords. He left no legitimate heir, and his cousin Stephen inherited his lands.
