William expected to receive the submission of the surviving English leaders after his victory, but instead Edgar the Ætheling was proclaimed king by the Witenagemot, with the support of Earls Edwin and Morcar, Stigand, the Archbishop of Canterbury, and Ealdred, the Archbishop of York. William therefore advanced on London, marching around the coast of Kent. He defeated an English force that attacked him at Southwark but was unable to storm London Bridge, forcing him to reach the capital by a more circuitous route.
