When Kveld-Ulf heard of his son's death, his grief was so great that he had to go to bed. But when he heard that it was the king who had slain him, and that he had fallen prone at his slayer's feet, he got up and was well content. For when a dying man fell on his face, it was a sign that he would be avenged. In the meanwhile, being far from powerful enough to attack Harold openly, the old man gathered all his family and his goods and set out for Iceland; but lingered long along the coast of Norway, in the hope of finding some one of Harold's race upon whom he could wreak vengeance. In this he was successful. The two sons of Guttorm, Harold's uncle and former guardian, were sailing northward with two of the king's men. These Bald Grim and Kveld-Ulf attacked, killed the king's cousins, and captured the ship. Then, wild with exultation, Bald Grim mounted the prow and sang: Now is the Hersir's vengeance On the king fulfilled. Wolf and eagle tread on Yngling's children. Seaward swept flew Halvard's Lacerated corpse, And the eagle's beak Tears Snarfare's wounds. From that time forth, there was a blood-feud between the Yngling race and Kveld-Ulf's descendants, and the famous saga of Egil, Bald Grim's son, tells of a long chain of bloody deeds which all had their origin in the king's treachery to Thorolf. Kveld-Ulf and Bald Grim were not the only chieftains who sought refuge abroad from Harold's oppression. After the battle of Hafrs-Fjord, when the king proceeded with uncompromising rigor to enforce the feudal system, several thousand men, many of whom belonged to the noblest families of the land, crossed the sea, and found new homes in the Orkneys and the Hebrides, whence again many found their way to Iceland. A great number also sailed direct for the latter country, and the so-called Landnama book (the Domesday Book of Iceland) has preserved the names, and, at times, bits of the history of the most important original settlers. Much as we may sympathize with the indomitable spirit which made these men sacrifice home and country for a principle, there is also another view of the case which has to be considered. Harold the Fairhaired was founding a state, which would support a higher civilization than could possibly be developed among a loose agglomeration of semi-hostile tribes. The idea of a national unity, which was the inspiration of his work, required the enforcement of an organic system which to the independent chieftains must have appeared extremely oppressive. The payment of taxes, which to the citizen of the modern state is not apt to appear humiliating, seemed to the Norse chieftains unworthy of a freeman. When Harold commanded them to refrain from robbing and plundering expeditions within the confines of his kingdom, they felt outraged, and could see no reason why they should submit to such unwarrantable curtailment of time-honored privileges.
