Touquet. William arrived soon afterward and ordered Guy to turn Harold over to him. Harold then apparently accompanied William to battle against William's enemy, Conan II, Duke of Brittany. While crossing into Brittany past the fortified abbey of Mont Saint-Michel, Harold is recorded as rescuing two of William's soldiers from quicksand. They pursued Conan from Dol-de-Bretagne to Rennes, and finally to Dinan, where he surrendered the fortress's keys at the point of a lance. William presented Harold with weapons and arms, knighting him. The Bayeux Tapestry, and other Norman sources, then record that Harold swore an oath on sacred relics to William to support his claim to the English throne. After Edward's death, the Normans were quick to point out that in accepting the crown of England, Harold had broken this alleged oath. The chronicler Orderic Vitalis wrote of Harold that he "was distinguished by his great size and strength of body, his polished manners, his firmness of mind and command of words, by a ready wit and a variety of excellent qualities. But what availed so many valuable gifts, when good faith, the foundation of all virtues, was wanting?" Due to a doubling of taxation by Tostig in 1065 that threatened to plunge England into civil war, Harold supported Northumbrian rebels against his brother, and replaced him with Morcar. This led to Harold's marriage alliance with the northern earls but fatally split his own family, driving Tostig into alliance with King Harald Hardrada ("Hard Ruler") of Norway. Reign At the end of 1065, King Edward the Confessor fell into a coma without clarifying his preference for the succession. He died on 5 January 1066, according to the Vita Ædwardi Regis, but not before briefly regaining consciousness and commending his widow and the kingdom to Harold's "protection". The intent of this charge remains ambiguous, as is the Bayeux Tapestry, which simply depicts Edward pointing at a man thought to represent Harold. When the Witan convened the next day they selected Harold to succeed, and his coronation followed on 6 January, most likely held in Westminster Abbey, though no evidence from the time survives to confirm this. Although later Norman sources point to the suddenness of this coronation, the reason may have been that all the nobles of the land were present at Westminster for the feast of Epiphany, and not because of any usurpation of the throne on Harold's part.
