The real story behind the best-known—and least-understood—battle in British history.   If ever there was a year of destiny for the British Isles, 1066 must have a strong claim. King Harold faced invasion not just from William and the Normans across the English Channel, but from King Harald Hardrada of Norway.   Before he fought the Normans at Hastings in October, he had fought at York and neighboring Stamford Bridge in September. It was a year of dramatic changes of fortune, heroic marches, assaults by land and sea. This concise history, with maps included, tells the full story.
