see Stephen in Bristol and consult about their moral dilemma: should they abandon their oaths of fealty to the King? Stephen agreed that, given the situation, he was prepared to release his subjects from their oath of fealty to him, and the clergy gathered again in Winchester after Easter to declare the Empress "Lady of England and Normandy" as a precursor to her coronation. When Matilda advanced to London in an effort to stage her coronation in June, though, she faced an uprising by the local citizens in support of Stephen that forced her to flee to Oxford, uncrowned. Once news of Stephen's capture reached him, Geoffrey of Anjou invaded Normandy again and, in the absence of Waleran of Beaumont, who was still fighting in England, Geoffrey took all the duchy south of the river Seine and east of the river Risle. No help was forthcoming from Stephen's brother Theobald this time either, who appears to have been preoccupied with his own problems with France—the new French king, Louis VII, had rejected his father's regional alliance, improving relations with Anjou and taking a more bellicose line with Theobald, which would result in war the following year. Geoffrey's success in Normandy and Stephen's weakness in England began to influence the loyalty of many Anglo-Norman barons, who feared losing their lands in England to Robert and the Empress, and their possessions in Normandy to Geoffrey. Many started to leave Stephen's faction. His friend and advisor Waleran was one of those who decided to defect in mid-1141, crossing into Normandy to secure his ancestral possessions by allying himself with the Angevins, and bringing Worcestershire into the Empress's camp. Waleran's twin brother, Robert of Leicester, effectively withdrew from fighting in the conflict at the same time. Other supporters of the Empress were restored in their former strongholds, such as Bishop Nigel of Ely, or received new earldoms in the west of England. The royal control over the minting of coins broke down, leading to coins being struck by local barons and bishops across the country. Stephen's wife Matilda played a critical part in keeping the King's cause alive during his captivity. Queen Matilda gathered Stephen's remaining lieutenants around her and the royal family in the south-east, advancing into London when the population rejected the Empress. Stephen's long-standing commander William of Ypres remained with the Queen in London; William Martel, the royal steward, commanded operations
