William Des Roches - King Philip Triumphant

King Philip Triumphant

William's family had originated from the lesser aristocracy, knights from Chateau-du-Loir, a castle that was granted as a dowry property of King Richard's widow, Berengaria of Navarre. Guillaume arranged for the exchange of his lordship of Le Mans (split with the bishop and the hereditary Manceaux seneschals, the 'Mauchien' family) for Berengaria's castle which he then became lord of. The exchange was ratified by King Philip.

King Philip had conquered Normandy (receiving the surrender of Peter de Preaux at Rouen in April 1204. Philip had then marched through Anjou and entered Poitiers after the death of Duchess Eleanor on April 1. It was in Poitiers that Philip officially granted the hereditary seneschalship on to William. By a later charter (1206) William received custody of Angers, Loudun, Saumur, Brissac, Beaufort, and "all the land of Anjou" at the King's pleasure. The lasting settlement arranged in 1208 had King Philip retain authority in Touraine with the castles of Chinon, Bourgueil, Loudun, Saumur, and Langeais. William was granted custody of all of Anjou and Maine including the fortresses of Bauge and Chateauneuf-sur-Sarthe. In addition, William was granted the "third penny" of justice in Anjou and one mark of silver per fifty livres of demesnial revenue. He was also permitted to assign baillis to assist him, Hamelin de Roorta being the most prominent. Coincidentally, Aimery of Thouars was conferred the seneschalship of Poitou by King Philip to similar terms with exception to the added revenue. King John's senechal of Poitou for 1205 had been Savaric of Mauleon, who was limited to the Aunis coastline and later in the year the castle of Niort.

Des Roches and Dreux of Mello, constable of France conducted the attack in Touraine culminating with capture of John's last Angevin fortresses, Chinon and Loches. Hubert de Burgh, John's castellan of both locations was forced to surrender in June 1205.

In 1206, John restabilized his rule in Poitou, Guienne, and Gascony, driving Castilian forces from Bourg, Bayonne, and Dax. Leading barons of Poitou preferred the absentee rule of King John to the more autocratic rule of King Philip; the Thouars, Mauleon, Lusignan, Parthenay, and Sugeres families all allied with King John. William set out with a force of knights to defend the Roman road connecting Tours and Poitiers. Other than a brief occupation of Angers, John was unsuccessful in making further progress north of the Loire. John departed after signing a two-year truce with King Philip that recognized the status quo. As soon as the truce was up in 1208, William and Dreux de Mello (based at Loches) collected some 300 knights and launched numerous attacks on Thouars holdings in Poitou.
