It is John of Hexham alone who mentions that the bishop himself had commenced operations by besieging the royal castle, which was held by a garrison of the Empress.[399] It was in this castle, says the Continuator, that she took up her quarters on her arrival.[400] She at once summoned the legate to her presence, but he, dreading that she would seize his person, returned a temporizing answer, and eventually rode forth from the city (it would seem, by the east gate) just as the Empress entered it in state.[401] Though the Continuator asserts that the Empress, on her arrival, found the city opposed to her, William of Malmesbury, whose sympathies were the same, asserts, on the contrary, that the citizens were for her.[402] Possibly, the former may only have meant that she had found the gates of the city closed against her by the legate. In any case, she now established herself, together with her followers, within the walls, and laid siege to the episcopal palace, which was defended by the legate's garrison.[403] The usual consequence followed. From the summit of the keep its reckless defenders rained down fire upon the town, and a monastery, a nunnery, more than forty (?) churches, and the greater part of the houses within the walls are said to have been reduced to ashes.[404] Meanwhile, the legate had summoned to his aid the Queen and all the royal party. His summons "was promptly obeyed;[405] even the Earl of Chester, "who," says Dr. Stubbs, "was uniformly opposed to Stephen, but who no doubt fought for himself far more than for the Empress,"[406] joined, on this occasion, the royal forces, perhaps to maintain the balance of power. But his assistance, naturally enough, was viewed with such deep suspicion that he soon went over to the Empress,[407] to whom, however, his tardy help was of little or no value.[408] From London the Queen received a well-armed contingent, nearly a thousand strong;[409] but Henry of Huntingdon appears to imply that their arrival, although it turned the scale, did not take place till late in the siege.[410]
