Västergötland and Norway and marched his troops by land and sea to the plain of Brávellir beneath the forest of Kolmården, close to the Bråviken bay. There he was met by the multi-ethic army of Harald, and the colossal Battle of Brávellir followed. In the end Ring beat his uncle, who was bludgeoned to death in the desperate fighting, and became the ruler of Denmark as well. He put an jarl in charge of Skåne and made a shieldmaiden the ruler of the rest of Denmark (cf. Chronicon Lethrense, below). Sigurd Ring (as he is now called in the text) married Alfhild, the daughter of King Gandalf Alfgeirsson of Alfheim (modern Bohuslän) and their son was Ragnar Lodbrok. As Sigurd grew old, distant parts of his realm began to secede, and it is told how he lost territory in England due to old age. A certain Adalbrikt (Æthelberht) took possession of Northumbria and was succeeded by his sons Ama and Ælla. One day, Sigurd was in Västergötland and was visited by his in-laws, the sons of Gandalf. They asked him to join them in attacking king Eysteinn of Vestfold in Norway. In Vestfold, there were great blóts held at Skiringssal. Unfortunately, Sögubrot (meaning the "fragment") ends there. However, the Skjöldunga saga is believed to be the original story on which Sögubrot is based and it continues the story (see below). Olaf Tryggvason's saga According to the extended Saga of Olaf Tryggvason, Sigurd Ring, after having stabilized his Swedish-Danish realm, recalled the lands in England once ruled by Harald Wartooth and Ivar Vidfamne. This territory was now ruled by Ingjald (Ingild), a brother of King Peter of Wessex and a mighty ruler in his own right. Ring therefore summoned the leiðangr and sailed to the west, reaching Northumbria. As Ingjald learned about the invasion, he gathered an army. In the ensuing battle, Ingjald and his son Ubbe (Eoppa) fell with a large part of their army. Ring now subordinated Northumbria and made Olaf Kinriksson tributary king. He was a grandnephew of Moald Digra, the mother of Ivar Vidfamne. Ring sailed back to his Nordic kingdom and Olaf reigned for a long time. Then, however, Eava (Eafa), the son of Ubbe, claimed the kingdom. Olaf was defeated and fled to his suzerain in Svíþióð. As compensation, Ring installed Olaf as sub-king in Jutland. As such he served Ring and later Ragnar Lodbrok.
