Complete story — includes the ending
As the great army assembles, Bjorn and Ivar argue over its leadership. Harald spots Ellisif, the woman he fell in love with years ago, who he had wanted to impress by conquering Norway. But she has since married a Danish earl, of lower status than him. Ubbe and Margrethe are married, but Ubbe agrees to share her with Hvitserk. Helga wants to join the great army with Tanaruz, but Floki is not happy with her decision. Harald and Halfdan have Egil infiltrate Kattegat. Halfdan suggests Harald kill Ellisif to regain his honor, but Harald refuses because she is the only woman he loves. Earl Jorgensen volunteers to be sacrificed to assure victory in the coming war, while Bjorn and Astrid continue their affair. Aethelwulf confronts Ecbert about his affair with Judith and questions Ecbert's love for him and his ability as a king. Ecbert asks him to lead the defence against the Norse invaders. As the great army lands in Northumbria, King Aelle's much smaller army is overrun, Aelle is captured, and killed by the blood eagle.
