Henry of Blois, the Bishop of Winchester, intervened in an attempt to produce a negotiated solution. Henry reached an agreement whereby after five weeks, the castle finally surrendered; the garrison were allowed to leave peacefully but the castle was handed over to the king. The deal struck by Miles and Henry appears to have left the surrounding estates in the hands of the Beauchamps, however, and in 1141 Miles returned and retook the castle itself, although no details are available as to how he achieved this.
