William the Conqueror's invasion in 1066 was not the only attack on England that year. On September 25, 1066, less than three weeks before William defeated King Harold II Godwinson at the battle of Hastings, that same Harold had been victorious over his other opponent of 1066, King Haraldr Hardradi of Norway, at the battle of Stamford Bridge. It was an impressive victory, driving an invading army of Norwegians from the earldom of Northumbria; but it was to cost Harold dear. In telling the story of this neglected battle, Kelly DeVries traces the rise and fall of a family of English warlords, the Godwins, as well as that of the equally impressive Norwegian warlord Hardradi.
