Channel, he was able to move his whole expedition to the mouth of the Somme, a necessary preliminary to attempting to cross the Channel. So large a fleet, consisting no doubt to a great extent of open boats, could not possibly have ventured to make the passage from the original point of assembly, which was doubtless selected as being more central to Normandy generally. Not for two or three weeks more did the necessary south wind blow. On September 27 the wind was at last favourable: next day William landed at Pevensey, and on the 29th occupied Hastings, where he formed a fortified camp to protect his ships. Nothing could have been more opportune for his interests: he had been unable to move while the English fleet was at sea, nor until Harold, far away in the north, had been weakened by the slaughter among his housecarls at Stamford Bridge. It was not the Norman's policy to plunge into a hostile country. Harold must needs come to meet him, and the nearer he could bring on a battle to his fleet, and therefore to his means of escape in case of defeat, the better for him. Accordingly he remained at Hastings, ravaging the country far and wide, partly for subsistence, partly to compel Harold to approach him.

A Sussex thegn soon brought the news to Harold: he had ridden the whole distance to York in three days, and found the king, so the story is told, at the banquet held in honour of his recent victory. Harold returned to London at once with his housecarls, summoning in all haste the forces of the south and east of England, which responded heartily to the call, the men of Kent and of London foremost. As soon as an adequate number was assembled, he marched straight to meet the invader. The king's exact movements cannot be traced, but the speed with which the whole was accomplished was extraordinary. In sixteen days at the latest from the time of William's landing, Harold and his army were close to him. In that time the news had been conveyed to York, the king's army had marched the whole way back, and men had been sent for and gathered from every shire from the Wash to the Exe. While in London, say the chroniclers, Harold was urged to let his brother Gyrth lead the army against the Norman, on the ground that, while he could not deny his promise to William, and there was a widespread fear of the wrath of the saints at his breaking the oath sworn on their relics, all this applied only to Harold personally. The king might stay in London, organise further levies, and by wasting the country render the advance of the invaders impossible: all would not be lost even if Gyrth were defeated. Harold rejected the well-meant advice; he would ask no one to run a risk he was not prepared to share, he would never harm those who were entrusted to his care. The decision was wise as well as chivalrous, in his peculiar position: his standing aloof would only have strengthened the superstitious awe which the maledictions of the Church on his perjury aroused, and given excuse for other defections than those for which Edwin and Morcar were responsible. Under ordinary circumstances a king's or a commander-in-chief's obvious duty is not to risk his own life. In Harold's case every consideration dictated his being personally foremost in the fight. It would have been well for England had he acted on the advice in a reversed sense, and left Gyrth behind in his stead. While Harold lived Gyrth was only of minor importance; when Harold had fallen, the cause of England might still have been sustained successfully by his brother.
