[1] It is essentially an adaptation of the German Hildebrandslied, but it has assimilated matter from the Tyrfing Cycle.
This Alf took Hildebrand's mother Hild captive and gave her to the champion Aki with whom she had the son Asmund.
The princess promised to marry Asmund, if he avenged her father and killed Hildebrand.
They fought well for a long time, until Hildebrand was severely wounded and his sword broke.
In Gesta Danorum 7:IX.2-X.1, Saxo Grammaticus tells an essentially identical saga, but all the names are different, with the figure corresponding to Hildebrand called Hildiger.
