 In 1058, a fleet under Harald's son Magnus supported a large scale Welsh raid into England, although details are limited.This may have shown Harald that he could not simultaneously fight Denmark and England; this became crucial when Edward died in January 1066, and Harold Godwinson proclaimed king of England.Harold's brother Tostig Godwinson, formerly Earl of Northumbria, now appeared on the scene; hoping to regain his titles and lands, he reportedly approached both William and Sweyn Estridsson for their support.
