A great battle ensued which Agne won and many Finns were killed together with Frosti. Agne then subdued all of Finland with his army, and captured not only great booty but also Frosti's daughter Skjalf and her kinsman Logi.
Agne returned to Sweden and they arrived at Stocksund (Stockholm) where they put up their tent on the side of the river where it is flat. Agne had a torc which had belonged to Agne's great-great-great-grandfather Visbur. Agne married Skjalf who became pregnant with two sons, Erik and Alrik.
Skjalf asked Agne to honour her dead father Frosti with a great feast, which he granted. He invited a great many guests, who gladly arrived to the now even more famous Swedish king. They had a drinking competition in which Agne became very drunk. Skjalf saw her opportunity and asked Agne to take care of Visbur's torc which was around his neck. Agne bound it fast around his neck before he went to sleep.
The king's tent was next to the woods and was under the branches of a tall tree for shade. When Agne was fast asleep, Skjalf took a rope which she attached to the torc. Then she had her men remove the tent, and she threw the rope over a bough. Then she told her men to pull the rope and they hanged Agne avenging Skjalf's father. Skjalf and her men ran to the ships and escaped to Finland, leaving her sons behind.
Ynglingatal then gives Alrekr and Eiríkr as Agne's successors.
The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:
Qui [Dagr] genuit Alrik; hunc frater suus Erikr freno percussit ad mortem. Alricr autem genuit Hogna; istum uxor sua juxta locum Agnafit, qui nunc Stokholmr dicitur, propriis manibus interfecit suspendendo ad arborem cum catena aurea. Cujus filius Ingialdr [...]
This man [Dag] engendered Alrek, who was beaten to death with a bridle by his brother, Eirik. Alrek was father to Agne, whose wife dispatched him with her own hands by hanging him on a tree with a golden chain near a place called Agnafit. His son, Ingjald, [...]
Agne is incorrectly called Hogne. Unlike Ynglingatal, Historia Norwegiæ does not give Dagr as Agne's predecessor, but Alrekr. Instead Alrekr is Agne's predecessor and Agne is succeeded by Yngvi (incorrectly called Ingialdr). The even earlier source Íslendingabók cites the line of descent in Ynglingatal and it gives the same line of succession as Historia Norwegiæ: xii Alrekr. xiii Agni. xiiii Yngvi.
