Stephen responded by seizing his personal wealth, which caused some discontent amongst the senior clergy. Henry wanted to succeed to the post, but Stephen instead supported Theobald of Bec, who was eventually appointed. The papacy named Henry papal legate, possibly as consolation for not receiving Canterbury. Stephen's first few years as king can be interpreted in different ways. He stabilised the northern border with Scotland, contained Geoffrey's attacks on Normandy, was at peace with Louis VI, enjoyed good relations with the church and had the broad support of his barons. There were significant underlying problems, nonetheless. The north of England was now controlled by David and Prince Henry, Stephen had abandoned Wales, the fighting in Normandy had considerably destabilised the duchy, and an increasing number of barons felt that Stephen had given them neither the lands nor the titles they felt they deserved or were owed. Stephen was also rapidly running out of money: Henry's considerable treasury had been emptied by 1138 due to the costs of running Stephen's more lavish court and the need to raise and maintain his mercenary armies fighting in England and Normandy. Defending the kingdom (1138–1139) Stephen was attacked on several fronts during 1138. First, Robert, Earl of Gloucester, rebelled against the King, starting the descent into civil war in England. An illegitimate son of Henry I and the half-brother of the Empress Matilda, Robert was one of the most powerful Anglo-Norman barons, controlling estates in Normandy. He was known for his qualities as a statesman, his military experience, and leadership ability. Robert had tried to convince Theobald to take the throne in 1135; he did not attend Stephen's first court in 1136 and it took several summonses to convince him to attend court at Oxford later that year. In 1138, Robert renounced his fealty to Stephen and declared his support for Matilda, triggering a major regional rebellion in Kent and across the south-west of England, although Robert himself remained in Normandy. In France, Geoffrey of Anjou took advantage of the situation by re-invading Normandy. David of Scotland also invaded the north of England once again, announcing that he was supporting the claim of his niece the Empress Matilda to the throne, pushing south into Yorkshire. Anglo-Norman warfare during the reign of Stephen was characterised by attritional military campaigns, in which commanders tried to seize key enemy castles in order to allow them to take
