Harold in Normandy

In 1064 Harold Godwinson met William, Duke of Normandy. Historical sources that have survived from this period give different reasons for this meeting. Some sources claim that strong winds forced the ship that Harold was on into a harbour controlled by Count Guy of Ponthieu. Harold was taken prisoner and then handed over to William.
However, Norman sources such as those written by William of Poitiers and William of Jumieges, claim that Harold Godwinson was sent to Normandy by Edward the Confessor to confirm that William was to become the next king of England. While there, Harold swore fealty to William and promised to be faithful to the future king.
