William II went to war again against le Petit Charlemagne in an effort to check his expansion in the pays de Vaud. Although no contemporary source describes the course of the war, it is evident that William was defeated. He lost the fortress of Les Clées, which commanded the pass into Burgundy, and that of Bourg-du-Four in the centre of Geneva. He was also forced to accept the arbitration of Peter's brother, Philip, Archbishop of Lyon, who in turn imposed a "Carthagenian settlement" on 28 June: the count was forced to cede to Peter a large gagerie as security against the payment of an indemnity set at 10,000 marks, which was half of the indemnity ordered in 1237. The gagerie comprised the castles of Geneva, Les Clées, Charousse, Ballaison, Rue; the homages of the Count of Gruyére and of the lords of Langin, Oron and Vufflens; and all the jurisdictions William possessed in the Pays de Vaud, the Chablais and in Faucigny, between the Arve and the Dranse and between the Cluse de Gex and the Pont de Bargen. By this concession the once powerful county of Geneva was reduced to little more than the Genevois. The archbishop further intervened in the dispute between William and Peter over Arlod, deciding that it should remain in Peter's possession until an inquiry could determine if it pertained to the sire of Gex or to the prior of Nantua, who happened at that time to be Boniface, brother of Peter and Philip. William II died at Domène in November 1252 and was succeeded by his eldest son, Rudolf, while his younger son, Henry, received the fortresses of Vuache and Ternier. Besides his sons Rudolf, Amadeus and Henry, William II had four others. One Savoyard Renaissance historian described William II as “quarrelsome”. Notes Bibliography Eugene L. Cox.
