When they had arrived at Granmar's kingdom, the poem deals with a flyting between Helgi's half-brother Sinfjötli and Höðbrodd's brother Guðmundr.
It is retold in detail about the gathering of the forces and of how, in a great battle, Helgi and his brother Sinfjötli fight with Högne, his son Dag, Granmar and all of Granmar's sons Hothbrodd, Starkad and Gudmund.
