“At last all Olaf’s ships had been cleared except the Long Serpent, which carried all the men who were able to fight. Eirik Jarl then attacked the Serpent with five large ships. He laid the Járnbardi alongside the Serpent, and then ensued the fiercest fight and the most terrible hand-to-hand struggle that could be....
“Eirik Jarl was in the foreroom of his ship, where a shieldburgh was drawn up. There was both hand-to-hand fight and spear-throwing and every kind of weapon was thrown, and whatever could be seized by the hand. Some shot with bows or with their hands, and such a shower of weapons was poured upon the Serpent that the men could hardly protect themselves against it. Then spears and arrows flew thickly, for on all sides of the Serpent lay warships. King Olaf’s men now became so furious that they jumped upon the gunwales in order to reach their foes with their swords and kill them, but many did not lay their ships so close to the Serpent as to get into the hand-to-hand fight, most of them thought it hard to deal with Olaf’s champions.
“The Northmen thought of nothing but continually going forward to slay their foes, and many went straight overboard; for out of eagerness and daring they forgot that they were not fighting on dry ground, and many sank down with their weapons between the ships....
“King Olaf Tryggvason stood on the lypting of the Serpent, and chiefly used during the day his bow and javelins; and always two javelins at a time. It was agreed by all, both friends and foes, who were present, and those who have heard these tidings told with the greatest truth, that they have known no man fight more valiantly than King Olaf Tryggvason. King Olaf surpassed most other kings, in that he made himself so easily known in the battle that men knew no example of any king having shown himself so openly to his foes, especially as he had to fight against such an overwhelming force. The king showed the bravery of his mind, and the pride of his heart, so that all men might see that he shunned no danger. The better he was seen and the greater lack of fear he showed in the battle, the greater fear and terror he inspired.
“King Olaf saw that his men on the fore part of the ship frequently raised their swords to strike, and that the swords cut badly. He cried out: ‘Why do you raise your swords so slowly? I see they do not bite?’ A man replied: ‘Our swords are both dull and broken, lord.’ The king then went down from the lypting into the foreroom and unlocked the high-seat chest, and took therefrom many bright and sharp swords, which he gave to his men. As he put down his right hand they saw that blood flowed out of the sleeve of the coat-of-mail, but no one knew where he was wounded.
“Hard and bloody was the defence of the foreroom men and the stem-defenders, for in both those places the gunwale was highest and the men picked. When the fall of men began on the Serpent, it was first amidships, mostly from wounds and exhaustion, and men say that if these brave men could have kept up their defence the Serpent would never have been won.
“When only a few were left on the Serpent around the mast amidships, Eirik Jarl boarded it with fourteen men. Then came against him the king’s brother-in-law, Hyrning, with his followers, and between them ensued a hard struggle, for Hyrning fought very boldly. It thus ended that Eirik Jarl retreated on to the Bardi; but of those who had followed him, some fell, and some were wounded; and Hyrning (Thor image) and Eirik Jarl became much renowned from this fight....
“Eirik Jarl took off the Bardi the dead and wounded, and in their stead brought fresh and rested men, whom he selected from among Swedes and Danes. It is also said by some that the Jarl had promised to let himself be baptized if he won the Serpent; and it is a proof of their statement that he threw away Thor and put up in his place a crucifix in the stem of the Bardi. When he had prepared his men, he said to a wise and powerful chief who was present, Thorkel the high, brother of Sigvaldi Jarl: ‘Often have I been in battles, and never have I before found men equally brave and so skilled in fighting as those on the Serpent, nor have I seen a ship so hard to win. Now as thou art one of the wisest of men, give me the best advice thou knowest how the Serpent may be won.’ Thorkel replied: ‘I cannot give thee sure advice thereon, but I can say what seems to me best to do. Thou must take large timbers, and let them fall from thy ship upon the gunwale of the Serpent, so that it will lean over; you will then find it easier to board the Serpent, if its gunwale is no higher than those of the other ships. I can give thee no other advice, if this will not do.’ The Jarl carried out what Thorkel had told him....
“When Eirik Jarl was ready he attacked the Serpent a second time, and all the Danish and Swedish host again made an onset on King Olaf Tryggvason; the Swedes placed their prows close to the Serpent, but the greatest part of the host was within shooting distance of the Northmen, and shot at them incessantly. The Jarl again laid the Bardi side by side with the Serpent, and made a very sharp onslaught with fresh men; neither did he spare himself in the battle, nor those of his men who were left.
“King Olaf and his men defended themselves with the utmost bravery and manliness, so that there was little increase in the fall of men on the Serpent while they were fresh; they slew many of their foes, both on the Járnbardi and on other ships which lay near the Serpent. As the fight still went against Eirik Jarl, he hoisted large timbers on the Bardi, which fell on the Serpent. It is believed that the Serpent would not have been won but for this, which had been advised by Thorkel the high.
