His brother said that "it would be the most noble marriage in the Northlands to have the daughter of the king at Uppsala for wife" and "many have little courage in a big body and it is a shame that you who are a man durst not speak to womenfolk".
When Hrólfr proposed, she rushed up, grabbed her weapons and ordered his men to "fetch and bind the fool who offended king Þórbergr".
Hrólfr put on his helmet and asked his housecarls to leave and then he manfully slew no less than twelve of Þorbjörg's champions before he had to flee the overwhelming foe.
After a Viking campaign in the West to both Scotland and Brittany, Hrólfr steered his fleet of six ships and a selected crew northwards and did not stop until he reached Uppsala.
After a hard fight Þorbjörg was captured and eventually she fell in love with Hrólf son of Gautrek and agreed to marry him, at which point she gave up her weapons to her father King Eirík and took up embroidery.
