began to bellow, the enemies began to fight between themselves. When Ragnar Lodbrok was visiting Eysteinn at Uppsala, Eysteinn suggested that Ragnar marry Ingeborg and have her as wife instead of the pauper Aslaug (Kraka). Ragnar consequently betrothed himself to Ingeborg. Eventually, Aslaug found out from three small birds, and told Ragnar that she was no pauper. She was the daughter of Sigurd and Brynhild. As Ragnar understood that Kraka was of better descent than that of Ingeborg, he decided not to go back to Sweden and wed Eysteinn's daughter. Eysteinn was upset with Ragnar's change of plans and declared that their friendship was no more. This was interesting news to Ragnar's sons Eric and Agnar who decided to go to Sweden and pillage, as their father would not mind anymore.

Sigurd's foster-father assembled five longships for him. Hvitserk and Björn Ironside mustered fourteen, while Aslaug and Ivar the Boneless marshalled ten ships each. Ivar would not allow his mother Aslaug to go by sea, but she could join the army of riders that would go across land. She accepted and changed her name to Randalin. When the armies met in battle, Ivar told everyone to make such a din that the bellowing from Sibilja could not be heard. This was of no use, however, and so Ivar shot
