The death of the young William was a signal to set Henry's enemies in motion again. But they did not begin at once. Henry's position was still unweakened. Very likely his speedy marriage was a notice to the world that he did not propose to modify in the least his earlier plans. Probably also the absence of Fulk of Anjou, who had gone on a pilgrimage to Jerusalem soon after his treaty of 1119 with Henry, was a cause of delay, for the natural first move would be for him to demand a return of his daughter and her dowry. Fulk's stay was not long in the land of which he was in a few years to be king, and on his return he at once sent for his daughter, probably in 1121. She returned home, but as late as December, 1122, there was still trouble between him and Henry in regard to her dowry, which Henry no doubt was reluctant to surrender. About the same time, Henry's old enemy, Amaury of Montfort, disliking the strictness of Henry's rule and the frequency of his demands for money, began to work among the barons of Normandy and with his nephew, the Count of Anjou, in favour of William Clito. It was already clear that Henry's hope of another heir was likely to be disappointed, and Normandy would naturally be more easily attracted to the son of Robert than England The first step was one which did not violate any engagement with Henry, but which was, nevertheless, a decided recognition of the claims of his nephew, and an open attack on his plans. Fulk gave his second daughter, Sibyl, in marriage to William Clito, and with her the county of Maine, which had been a part of Matilda's dower on her marriage with Henry's son William. Under the circumstances, this was equivalent to an announcement that he expected William Clito to be the Duke of Normandy. Early in 1123, Henry sent over troops to Normandy, and in June of that year he crossed himself, to be on the spot if the revolt and war which were threatening should break out. In September the discontented barons agreed together to take arms. It is of interest that among these was Waleran of Meulan, the son of the king's faithful counsellor, Count Robert. Waleran had inherited his father's Norman possessions while his brother Robert had become Earl of Leicester in England.
