Over the seas in Normandy, William had heard in simple but sufficient language of all that had taken place at Westminster in those first days of the year 1066. A messenger, who had come on an English ship, brought the news, "King Edward has ended his days, and Earl Harold is raised to the kindom."
William's wrath was intense. "Oft times he laced, and as oft unlaced his mantle; he spake to no man, and no man dared speak to him." The crown of England he declared was his and his alone, promised to him by Edward years before, when he went on a visit to the English court, and Harold, shipwrecked on the coast of Normandy, had sworn to support his claim. At once he sent a message, or probably several messengers to Harold, demanding from him the crown. The Englishman's answer was given with no uncertain sound. Had William really been chosen king by Edward and the Witan, he would have supported him, but things were all changed now, and he, Harold, could not give up a crown set on his head by the will of the nation, except at the nation's will. William then decided on an appeal to force. His people, bold and adventurous, rallied to his side, and set about preparing a fleet in which to cross the seas, and his chief counsellor, the Abbot Lanfranc, obtained for him from Rome the sanction and blessing of the Church on his undertaking, representing that it would be for the spiritual welfare of England. For even in those early days England had shown an independence and a restiveness under Roman control which could not be allowed to continue unrebuked.
William was indeed a formidable foe, and he was not the worst or only foe, for Harold was suddenly called on to face his own brother, Tostig, who had turned against him, demanding half the kingdom, and who to enforce this claim had enlisted on his side Harald Hardrada, the warrior king of Norway, whose fame as a fighter was known from Iceland to Africa. With an army, these two landed in the North and moved on to York, fighting their way victoriously. But from London Harold was marching at the head of his house-carls, drawing into his train ready volunteers. As they came along the Roman road with a speed almost incredible, their hearts beating high at the thought of an encounter with traitors and a foreign foe, they told one another how King Edward had appeared to Harold on the night before their start, bidding him be strong and very courageous, for the victory would be surely his. On the 25th of September the armies faced each other, and there came a messenger from the enemy's camp offering terms. Harold's answer was characteristic. To his brother he promised peace and forgiveness, "for he is an Englishman. But to Harald Hardrada, who is a foreigner and an enemy, I will give him six feet of English ground; or, as I hear he is taller than most men, I will give him seven feet. But this is all the English ground he will get from me."
