However, the Viking warriors in the Seine continued their raids during the following years and even plundered Paris again in 861. In his despair Charles the Bald tried to use another Viking chief, Veland, whose men operated in the Somme region, to attack the Seine Vikings at Oissel. However, this scheme backfired since the two Viking armies made a deal and united their forces. The Norsemen were encamped by the lower Seine in 861–862, but then split again. Veland agreed to become a Christian and joined royal service, while the Seine Vikings went to sea. Some of them joined the fighting between the ruler of Bretagne and some Frankish counts.

Ragnar's sons Eric and Agnar then sailed into Lake Mälaren and sent a message to the Swedish King Eysteinn, a vassal of Ragnar, that they wanted him to submit to Ragnar's sons. Moreover, Eric said that he wanted Eysteinn's daughter Borghild as wife. Eysteinn said that he first wanted to consult the Swedish chieftains. The chieftains said no to the offer, and ordered an attack on the rebellious sons. A battle ensued and Eric and Agnar were overwhelmed by the Swedish forces, whereupon Agnar died and Eric was taken prisoner. Eysteinn offered Eric as much of Uppsala öd as he wanted, and Borghild, in wergild for Agnar. Eric proclaimed that after such a defeat he wanted nothing but to choose the day of his own death. Eric asked to be impaled on spears that raised him above the dead and his wish was granted. In

According to the saga, their father Ragnar was captured and killed by King Ælla in England after a foolhardy invasion attempt. Björn and his brothers, seeking revenge, attacked Ælla but were beaten back. As Ivar realised that the English king could not be defeated right away, he sought reconciliation. He only asked for as much land as he could cover with an ox's hide and swore never to wage war against Ælla. Then Ivar cut the ox's hide into such fine strands that he could envelop a large fortress (in an older saga it was York and according to a younger saga it was London) which he could take as his own. Ivar made himself popular in England and asked his brothers to attack again. During the battle Ivar sided with his brothers and so did many of the English chieftains with their people, in loyalty to Ivar. Ælla was taken captive and in revenge they carved the blood eagle on him. Later Björn and his brothers pillaged in England,

, Sörle. He therefore invaded the Swedish lands in company with his sons Björn, Fridleif and Radbard. Before battle had broken out, the opposing sides agreed to settle the matter through a combat. Ragnar and his three sons met the renowned champion Starkad and his seven sons in the sight of the two armies. "Björn, having inflicted great slaughter on the foe without hurt to himself, gained from the strength of his sides, which were like iron, a perpetual name .e., Ironside. Ragnar and his sons slew their eight opponents, after which their troops fell on Sörle and his army and annihilated them. Ragnar then "presented Björn with the lordship of Sweden for his conspicuous bravery and service." Later on, another son of Ragnar, Ubbe, colluded with his maternal grandfather Esbjörn and conspired against Ragnar. Esbjörn sent envoys to Björn in Sweden to drum up support for a rebellion, but Björn refused to listen. Instead, he hanged the envoys while their party were slaughtered by the Swedes. Shortly afterwards Esbjörn was slain in a sea battle, and Ubbe was captured after a heroic resistance. In due time Ragnar appointed Björn regent of Norway, while Sweden was handed over to another son, Eric Weatherhat. After the death of Ragnar, Björn and his brothers attacked Ella in England with 400 ships and killed him. He then went back to his Swedish kingdom, but intervened in Denmark when the Danes rose against the rule of Ragnar's sons. With a fleet of 1,700 ships, he and his brothers crushed the insurgents at Slesvig. This is the last we hear about Björn Ironside in the ''Gesta Danorum''. The '' Hervarar saga'' from the 13th century tells that Eysteinn Beli was killed by Björn and his brothers as told in ''Ragnar Lodbrok's saga'', and they conquered all of Sweden.

Ubbe is sometimes labeled the "Frisian Jarl" and the invaders are occasionally called Scaldingi (men from Schelde).
