Stephen responded quickly to the revolts and invasions, paying most attention to England rather than to Normandy. His wife Matilda was sent to Kent with ships and resources from Boulogne, with the task of retaking the key port of Dover, under Robert's control. A small number of Stephen's household knights were sent north to help the fight against the Scots, where David's forces were defeated later that year at the Battle of the Standard. Despite this victory, however, David still occupied most of the north. Stephen himself went west in an attempt to regain control of Gloucestershire, first striking north into the Welsh Marches, taking Hereford and Shrewsbury, before heading south to Bath. The town of Bristol itself proved too strong for him, and Stephen contented himself with raiding and pillaging the surrounding area. The rebels appear to have expected Robert to intervene with support, but he remained in Normandy throughout the year, trying to persuade the Empress Matilda to invade England herself. Dover finally surrendered to the Queen's forces later in the year.
