The Danish king, Svein Tjuguskeg, was married, as before related, to Sigrid the Haughty. Sigrid was King Olaf Trygvason's greatest enemy; the cause of which, as before said, was that King Olaf had broken off with her, and had struck her in the face. She urged King Svein much to give battle to King Olaf Trygvason; saying that he had reason enough, as Olaf had married his sister Thyre without his leave, "and that your predecessors would not have submitted to." Such persuasions Sigrid had often in her mouth; and at last she brought it so far that Svein resolved firmly on doing so. Early in spring King Svein sent messengers eastward into Svithjod, to his son-in-law Olaf, the Swedish king, and to Earl Eirik; and informed them that King Olaf of Norway was levying men for an expedition, and intended in summer to go to Vindland. To this news the Danish king added an invitation to the Swedish king and Earl Eirik to meet King Svein with an army, so that all together they might make an attack; on King Olaf Trygvason. The Swedish king and Earl Eirik were ready enough for this, and immediately assembled a great fleet and an army through all Svithjod, with which they sailed southwards to Denmark, and arrived there after King Olaf Trygvason had sailed to the eastward. Haldor the Unchristian tells of this in his lay on Earl Eirik:-- "The king-subduer raised a host Of warriors on the Swedish coast. The brave went southwards to the fight, Who love the sword-storm's gleaming light; The brave, who fill the wild wolf's mouth, Followed bold Eirik to the south; The brave, who sport in blood--each one With the bold earl to sea is gone." The Swedish king and Earl Eirik sailed to meet the Danish king, and they had all, when together, an immense force. 109. EARL SIGVALDE'S TREACHEROUS PLANS.
