heard this they did the same thing and allied with Granmar's father-in-law Högne, the king of East Götaland, and his son Hildur. Ingjald invaded Södermanland with superior forces, and a battle commenced. After some ferocious fighting, the chiefs of Fjärdhundraland, West Götaland, Nerike and Attundaland began to flee from the battle in their ships. Ingjald was severely wounded and Svipdag the Blind and his sons Gautvid and Hylvid fell. Ingjald retreated and returned to Uppsala and realised that the forces he had gained from the conquered petty kingdoms were not faithful to him. After a long standstill, some friends of both sides wanted to bring about a reconciliation. Ingjald had a meeting with Granmar and Hjörvard and they decided to have peace for as long as the three men lived. The following spring, Granmar was travelling to Uppsala to confirm the peace between him and Ingjald, but he realised that Ingjald had not promised him a long life and so he returned. The next autumn, King Granmar and Hjörvard were at a feast in one of their farms on the island Selaön. During the night, they were surrounded by Ingjald and his men and the hall was set on fire burning everyone inside to death. Ingjald then installed chiefs to rule Södermanland. King Högne of East Götaland and his son Hildur often made raids into the Swedish provinces killing many of Ingjald's men. Högne defended his kingdom successfully until he died. King Hogne was reported to be killed with a son Bragi by Helgi the Ylfing from the legends of Helgi Hundingsbane and his daughter taken by Helgi as a wife. The sons of Granmer unnamed by Snorri were also killed by Helgi as Snorri relates he only had a daughter. This could be true if they were killed before Hildagun married Hjörvard the Ylfing. This suggests he was involved in a civil war with Hogne, Granmer, and Hjörvard, and him possibly being allied with Ingjald who was reported to kill Granmer and Hjörvard. Helgi was later killed by Dag another son of Hogne unnamed by Snorri. Dag could be Hildur as Bragi was killed by Helgi, this is unclear. More unclear is Hothbrod trying to marry Sigrun daughter of Hogne, as Granmer was married to Hilda daughter of Hogne. This would make Sigrun his aunt. More likely, Helgi killed Granmers sons as rivals to his own claim and possibly
