They had now hard work to ward off the arrows that came whistling from the "Long Serpent," for at such close quarters Erik had been recognized, and more than one archer shot at him. The "Saga" tells how young Einar Tamberskelver, the best of the bowmen of Norway, so strong that he could send a blunt arrow through a bull's hide, had posted himself in the rigging of the "Long Serpent" and made the rebel Jarl his mark. His arrows rattled on the shields of Erik's guard. One of them grazed his helmet, whistled over the "Iron Beard's" deck and buried itself in her rudder-head. Crouching in the bow of the "Iron Beard" behind her armour plates was a Finnish archer, and the Finlanders were such good bowmen that men said sorcery aided their skill. Erik told him to shoot the man in the "Serpent's" rigging. The Finn, to show his marksmanship, aimed at Einar's bowstring and cut it with his arrow. The bow released from the string sprang open and broke with a loud report. "What is that sound?" asked Olaf. Einar sprang down from the rigging and answered, "It is the sound of the sceptre of Norway falling from your grasp." It was noticed that Olaf's hand was bleeding, "his gauntlet was full of blood," but he had given no sign when he was wounded. Arrows, javelins, and stones were falling in showers on the decks of the "Crane" and the "Serpents," for the Danes and Swedes worsted in the close fight had drawn off a little, and were helping Erik's attack by thus fighting at a safer distance. Erik now boarded the "Long Serpent" amidships, but was beaten back. He brought up more of his ships and gathered a larger boarding-party. The Danish and Swedish arrows had thinned the ranks of Ulf's men in the "Long Serpent's" bows. When Erik led a second storming-party on board, Danes and Swedes too came clambering over the bow, and the "Long Serpent" attacked on all sides was cleared to the poop. Here Olaf fought with Kolbiorn, Einar and the men of the Shield-burg around him. He was somewhat disabled by his wounded hand, but he still used his battle-axe with deadly effect. The attacking party were not quite sure which of the tall men in gilded armour was the King, but at such close quarters some of them soon recognized him, and Erik called to his men not to kill Olaf, but to make him prisoner. Olaf knew well that if his life was spared for a while it would be only to put him to death finally with the cruelty the heathen Vikings delighted in inflicting on their enemies. As his men fell round him and his party was driven further and further astern, he must have seen that, outnumbered as his men were, and with himself wounded, he would soon be overmastered and made prisoner. There was just one chance of escape for the best swimmer in Norway. Holding up his shield he stepped on the bulwark, threw the shield at his enemies, and dived overboard. Kolbiorn tried to dive with him, but was seized and dragged back to the ship. When Erik found he was not the King he spared his life.
