Meanwhile, news of Henry's death had reached Stephen of Blois, conveniently placed in Boulogne, and he left for England, accompanied by his military household. Robert of Gloucester had garrisoned the ports of Dover and Canterbury and some accounts suggest that they refused Stephen access when he first arrived. Nonetheless Stephen reached the edge of London by 8 December and over the next week he began to seize power in England. The crowds in London proclaimed Stephen the new monarch, believing that he would grant the city new rights and privileges in return, and his brother, Henry of Blois, the bishop of Winchester, delivered the support of the Church to Stephen. Stephen had sworn to support Matilda in 1127, but Henry convincingly argued that the late King had been wrong to insist that his court take the oath, and suggested that the King had changed his mind on his deathbed. Stephen's coronation was held a week later at Westminster Abbey on 26 December.
