She was taken by Odda the Younger, another Wessex ealdorman, to the north. Staying with the Danes in the city over the winter, he again meets Ragnar, who saves him from death when Guthrum breaks the peace and murders the other Saxon hostages. Afterwards, he takes part in a siege against Guthrum, and is among a group of hostages exchanged when the Danes and Saxons make peace. He is not told that, by marrying her, he will also assume her family's very large debt to the Church. Seeking to take command of the fleet, Uhtred gains it on the condition that he marry the orphaned Wessex girl Mildrith. They part friends, swearing that one day they will band together to take revenge on Kjartan and rescue Thyra. After a battle with the Danes, he meets Ragnar the Younger, Earl Ragnar's eldest son, and tells him how his father died and that Thyra was kidnapped. There he learns to read and write, and sails with Alfred's fleet of 12 ships against the Danes. Uhtred hopes to escape Kjartan's assassins by spreading the rumour that he too died in the hall-burning. Ragnar remains inside, preferring to die on his terms rather than at Kjartan's hands. Uhtred enjoys life with the Danes, but flees after Kjartan and his men set fire to Ragnar's hall and kill everyone who tries to flee. He then escapes from Wessex and rejoins Ragnar. He is kidnapped by a priest, Beocca, an old family friend. Uhtred then goes viking across East Anglia, and participates in the conquests of Mercia and East Anglia, and the invasion of Wessex. He also crushes one of Sven's eyes with the hilt of his sword - adding darkly that he would have crushed both, had Sven stripped Thyra completely naked. Ragnar dismisses Kjartan from his service when Kjartan makes light of his son's behaviour. Uhtred, Rorik, and Thyra escape back to Ragnar's hall. Uhtred charges Sven from hiding, taking Sven's sword and attacking him with it. One day, Sven kidnaps Ragnar's daughter, Thyra, and removes part of her clothing in an effort to sexually assault her. Uhtred befriends Ragnar's youngest son, Rorik, and has many clashes with one boy in particular, Sven, son of Kjartan, one of Ragnar's shipmasters. Uhtred's uncle, Ælfric, takes Bebbanburg and usurps the title of ealdorman from Uhtred, the rightful heir. Ragnar, amused by the boy's bravery during the battle, keeps him as a thrall. Ealdorman Uhtred is killed during a disastrous attack on Danish-seized Eoferwic ( York) and his son is captured by Danish Jarl Ragnar the Fearless. Ealdorman Uhtred renames his next oldest son, Osbert, Uhtred.

Danes arrive on Bebbanburg's shores, and Ealdorman Uhtred's first son, also called Uhtred, is killed while scouting. Osbert is the second son of Ealdorman (Earl) Uhtred, Lord of Bebbanburg in Northumbria.
