William was hot-tempered and haughty, but prudent and sensible. He convoked at Lillebonne a great assembly of men from every state of Normandy, the richest and most esteemed of their class. He unfolded his plans to them, and they retired to discuss them at their ease, out of the presence of the duke.

The excitement was great and the opinions various. William, son of Osbert, appeared in the midst of the groups. "Why do you discuss together?" he exclaimed. "He is your lord, and he has need of your services; your duty would be to make offers to him, and not to wait until he asks for anything. If you fail him, and he attains his object by the will of God, he will not forget it; show, therefore, that you love him and support him with a will." Low murmurs were heard; the opposition was beginning to burst forth. "No doubt he is our lord," they said; "but is it not enough for him that we should pay his taxes? We do not owe him any assistance for his foreign excursions; he has already oppressed us too much by his wars; if his new enterprise should fail, our country would be ruined." The offers accordingly were few, when Osbert's son was instructed to communicate them to William.

The assembly re-entered the room wherein the duke sat. The seneschal advanced. "Sire," he said, "I do not think that there are in the world men more zealous than these. You know how many burdens they have already borne for you? Well, they propose to add another, and to follow you to the other side of the sea as they do on this side. Push onward, then, and fear nothing; whoever has hitherto only supplied you with two good soldiers on horseback is willing to bear double the expense." The seneschal was interrupted by a hundred voices crying "We did not commission you to make such an answer as that. Let him remain in his own territory, and we will serve him as we should do; but we are not compelled to help him to conquer another people's country. Besides, if we were for once to do him this service, he would expect it as a right ever afterwards, and would thereby oppress our children; it shall not be." And the assembly dispersed in anger.

The duke sent for the noblemen, one after the other, as well as the abbots and the merchants: he showed his plans to them, asked for their support as a personal favor which should not compromise their liberty in any way in future, and by degrees he obtained what he wanted. The merchants promised vessels and armed warriors, the priests gave money, and the barons placed themselves and their vassals at his disposition. The preparations began forthwith in all the Norman towns; adventurers were everywhere crowding round William, "who slighted nobody," according to the chronicles, "and was always ready to oblige people as far as he was able." He promised lands, castles, women, plunder; he even sold an English bishopric to a certain Rémi, of Fécamp, for a ship and twenty warriors.

While the noise of hammers was resounding throughout all the shipyards of Normandy, the ice had thawed in the Baltic, and Harold Hardrada had set sail with his sea-serpents; he had been joined by Tostig, and had ascended the Humber and the Ouse, causing great destruction on his way. A certain number of Englishmen had rallied round the standard of Tostig. Edwin and Morcar marched to oppose the allies, but they were repulsed with loss. The citizens of York, fearing an assault, promised to surrender. The Norwegians were already celebrating the victory in their camp.

It was in the early morning, and Hardrada and Tostig, with a small body of troops, were advancing towards York to hold an interview with the chiefs of the town. Counting upon the terror which they inspired among the peaceful citizens, they were but half armed; Harold Hardrada had left his halbert in his tent, and wore a blue tunic embroidered with gold and a helmet ornamented with precious stones. Suddenly a cloud of dust, which was rising in the horizon, cleared away and revealed a forest of lances. It was King Harold whom the invaders believed to be in the South watching the movements of the Duke of Normandy, and who had come by forced marches to encounter them. The golden dragon of Wessex was displayed on his standard.

The position of the Norwegian, Hardrada, was critical, but his courage did not desert him. Planting in the ground his banner, the motto on which was "The despoiler of the world," he drew up around it all his forces at the foot of Stamford Bridge; he was riding backwards and forwards in front of his soldiers, when his horse stumbled and he fell. "A good omen!" he cried when he saw the faces of the pirates darken. His soldiers, resting their lances on the ground, with their points in the direction of the enemy, awaited the onslaught of the English. Hardrada was marching along the ranks, singing an improvised "skald." "Let us fight," he said, "let us march, although without any breast-plates beneath the edges of the blue steel; our helmets glisten in the sun; they are sufficient for brave warriors."

The English were contemplating these valiant preparations. A small band of men had detached themselves from the body of the army. "Where is Earl Tostig, son of Godwin?" asked one of the warriors clad in steel. "He is here!" cried Tostig himself, stepping out from the ranks. "Your brother salutes you," rejoined the Saxon; "he offers you peace, friendship, and your former honors." "This is a sensible offer," said Tostig, "and if my brother had made it a year ago he would have spared the lives of many brave men. And what does he offer to my noble ally, King Harold, son of Sigurd?" "Seven feet of English soil," haughtily replied the warrior, contemplating the Norwegian's huge person; "a little more, perhaps, for he is taller than most men." "Then," cried Tostig, "my brother. King Harold, may prepare for the fray. It shall not be said that the son of Godwin abandoned the son of Sigurd."
