On November 4, 1112, an advantage fell to Henry which may have gone far to secure him the remarkable terms of peace with which the war was closed. He arrested Robert of Bellême, his constant enemy and the enemy of all good men, "incomparable in all forms of evil since the beginning of Christian days." He had come to meet the king at Bonneville, to bring a message from Louis, thinking that Henry would be obliged to respect his character as an envoy. Probably the king took the ground that by his conduct Robert had forfeited all rights, and was to be treated practically as a common outlaw. At any rate, he ordered his arrest and trial. On three specific counts--that he had acted unjustly toward his lord, that summoned three times to appear in court for trial he had not come, and that as the king's viscount he had failed to render account of the revenues he had collected--he was condemned and sentenced to imprisonment. On Henry's return to England he was carried over and kept in Wareham castle, where he was still alive in 1130. The Norman historian Orderic records that this action of Henry's met with universal approval and was greeted with general rejoicing. During Lent of the next year, 1113, Henry made formal peace with both his enemies, the king of France and the Count of Anjou. The peace with the latter was first concluded. It was very possibly Fulk's refusal to recognize Henry's overlordship of Maine that occasioned the war. To this he now assented. He did homage for the county, and received investiture of it from the hand of the king. He also promised the hand of his daughter Matilda to Henry's son William. Henry, on his side, restored to favour the Norman allies of Fulk. A few days later a treaty was made at Gisors, with the king of France. Louis formally conceded to Henry the overlordship of Bellême, which had not before depended upon the duchy of Normandy, and that of Maine, and Britanny. In the case of Maine and of Britanny this was the recognition of long-standing claims and of accomplished facts, for Count Alan Fergant of Britanny, as well as Fulk of Anjou, had already become the vassal of Henry, and had obtained the hand of a natural daughter of the king for his son Conan, who in this year became count. But the important lordship of Bellême was a new cession. It was not yet in Henry's hands, nor had it been reckoned as a part of Normandy, though the lords of Bellême had been also Norman barons. Concessions such as these, forming with Normandy the area of many a kingdom, were made by a king like Louis VI, only under the compulsion of necessity. They mark the triumph of Henry's skill, of his vigorous determination, and of his ready disregard of the legal rights of others, if they would not conform to his ideas of proper conduct or fit into his system of government. The occupation of Bellême required a campaign. William Talvas, the son of Robert, while himself going to defend his
