The Battle of London Bridge.
The Danish forces are stopped at the fortified London Bridge, guarded by Thorkell the Tall - a fearsome Dane who is supporting the English. Askeladd offers Thorfinn another duel if he can deliver Thorkell's head. Thorfinn attacks Thorkell, but the giant Viking is too experienced and Thorfinn has to retreat with his injuries. Arriving at an impasse, King Sweyn leaves his son, the Prince Canute to maintain the siege with Ragnar, while the rest of the army heads to Wessex.
