When this son had grown up somewhat, his wit, despite his tender years, equalled the discernment of manhood.

For he took to loving his mother, since she had had converse with a noble bed, but cast off all respect for his father, because he had stooped to a union too lowly.
After this Ragnar prepared an expedition against the Hellespontines, and summoned an assembly of the Danes, promising that he would give the people most wholesome laws.

He had enacted before that each father of a household should offer for service that one among his sons whom he esteemed least; but now he enacted that each should arm the son who was stoutest of hand or of most approved loyalty.

Thereon, taking all the sons he had by Thora, in addition to Ubbe, he attacked, crushed in sundry campaigns, and subdued the Hellespont with its king Dia.

At last he involved the same king in disaster after disaster, and slew him.
Dia's sons, Dia and Daxo, who had before married the daughters of the Russian king, begged forces from their father-in-law, and rushed with most ardent courage to the work of avenging their father.
