A man called Thrand Gialdkere was the steersman of King Inge's ship. It was come so far, that Inge's men were rowing in small boats between the ships after those who were swimming in the water, and killed those they could get hold of. Sigurd Slembe threw himself overboard after his ship had lost her crew, stripped off his armour under the water, and then swam with his shield over him.
Some men from Thrand's vessel took prisoner a man who was swimming, and were about to kill him; but he begged his life, and offered to tell them where Sigurd Slembe was, and they agreed to it.
Shields and spears, dead men, weapons, and clothes, were floating all around on the sea about the ships,
"Ye can see,"
"a red shield floating on the water; he is under it."
They rowed to it immediately, took him, and brought him on board of Thrand's ship. Thrand then sent a message to Thjostolf, Ottar, and Amunde. Sigurd Slembe had a tinder box on him; and the tinder was in a walnut-shell, around which there was wax. This is related, because it seems an ingenious way of preserving it from ever getting wet.
He swam with a shield over him, because nobody could know one shield from another where so many were floating about; and they would never have hit upon him, if they had not been told where he was. When Thrand came to the land with Sigurd, and it was told to the troops that he was taken, the army set up a shout of joy.
When Sigurd heard it he said,
"Many a bad man will rejoice over my head this day."
Then Thjostolf Alason went to where Sigurd was sitting, struck from his head a silk hat with silver fringes, and said.
"Why wert thou so impudent, thou son of a slave! to dare to call thyself King Magnus Barefoot's son?"
"Presume not to compare my father to a slave; for thy father was of little worth compared to mine."
Hal, a son of the doctor Thorgeir Steinson, King Inge's court- man, was present at this circumstance, and told it to Eirik Odson, who afterwards wrote these relations in a book, which he called "Hryggjarstykke". In this book is told all concerning Harald Gille and his sons, and Magnus the Blind, and Sigurd Slembidjakn, until their deaths.
Eirik was a sensible man, who was long in Norway about that time. Some of his narratives he wrote down from Hakon Mage's account; some were from lendermen of Harald's sons, who along with his sons were in all this feud, and in all the councils. Eirik names, moreover, several men of understanding and veracity, who told him these accounts, and were so near that they saw or heard all that happened. Something he wrote from what he himself had heard or seen.
