According to that traditional literature, Ragnar distinguished himself by many raids against Francia and Anglo-Saxon England during the 9th century.

In the early 18th century, a barrow on the island of Munsö was claimed by antiquarians to be Björn Järnsidas hög or Björn Ironside's barrow.
Helgi escaped from the battle with Sigurd Snake-in-the-Eye's banner, sword and shield. He went to Denmark and informed Sigurd's mother Aslaug of her loss.
