1144 he advanced into Rouen, the capital of the duchy, concluding his campaign. Louis VII recognised him as Duke of Normandy shortly after. By this point in the war, Stephen was depending increasingly on his immediate royal household, such as William of Ypres and others, and lacked the support of the major barons who might have been able to provide him with significant additional forces; after the events of 1141, Stephen made little use of his network of earls. After 1143 the war ground on, but progressing slightly better for Stephen. Miles of Gloucester, one of the most talented Angevin commanders, had died whilst hunting over the previous Christmas, relieving some of the pressure in the west. Geoffrey de Mandeville's rebellion continued until September 1144, when he died during an attack on Burwell. The war in the west progressed better in 1145, with the King recapturing Faringdon Castle in Oxfordshire. In the north, Stephen came to a fresh agreement with Ranulf of Chester, but then in 1146 repeated the ruse he had played on Geoffrey de Mandeville in 1143, first inviting Ranulf to court, before arresting him and threatening to execute him unless he handed over a number of castles, including Lincoln and Coventry. As with Geoffrey, the moment Ranulf was released he immediately rebelled, but the situation was a stalemate: Stephen had few forces in the north with which to prosecute a fresh campaign, whilst Ranulf lacked the castles to support an attack on Stephen. By this point, however, Stephen's practice of inviting barons to court and arresting them had brought him into some disrepute and increasing distrust. Final phases of the war (1147–1152) England had suffered extensively from the war by 1147, leading later Victorian historians to call the period of conflict "the Anarchy". The contemporary Anglo-Saxon Chronicle recorded how "there was nothing but disturbance and wickedness and robbery". Certainly in many parts of the country, such as Wiltshire, Berkshire, the Thames Valley and East Anglia, the fighting and raiding had caused serious devastation. Numerous "adulterine", or unauthorised, castles had been built as bases for local lords—the chronicler Robert of Torigny complained that as many as 1,115 such castles had been built during the conflict, although this was probably an exaggeration as elsewhere he suggested an alternative figure of 126. The previously centralised royal coinage system was fragmented, with Stephen, the Empress and local lords all minting their
