The Chronicle of The Kings of Norway
Part 20 - Death Of Frirek Keina And Bjarne
Erling Skakke made ready to sail in spring as soon as he could get his ships afloat for ice, and sailed from Konungahella; for he heard that those who had formerly been Markus's friends were marauding in the north of Viken. Erling sent out spies to learn their doings, searched for them, and found them lying in a harbour.
Onund Simonson and Ornolf Skorpa escaped, but Frirek Keina and Bjarne the Bad were taken, and many of their followers were killed. Erling had Frirek bound to an anchor and thrown overboard; and for that deed Erling was much detested in the Throndhjem country, for the most powerful men there were relatives of Frirek. Erling ordered Bjarne the Bad to be hanged; and he uttered, according to his custom, many dreadful imprecations during his execution.
Thorbjorn Skakkaskald tells of this business: —
"East of the Fjord beyond the land,
Unnoticed by the pirate band,
Erling stole on them ere they knew,
And seized and killed all Keina's crew.
Keina, fast to an anchor bound,
Was thrown into the deep-blue Sound;
And Bjarne swung high on gallows-tree,
A sight all good men loved to see."
Onund and Ornolf, with the band that had escaped, fled to Denmark; but were sometimes in Gautland, or in Viken.
