Sandwich. He went very quickly about East Anglia into the Humber's mouth, and so upward along the Trent till he came to Gainsborough. Earl Uchtred and all Northumbria quickly bowed to him, as did all the people of the Kingdom of Lindsey, then the people of the Five Boroughs. He was given hostages from each shire. When he understood that all the people had submitted to him, he bade that his force should be provisioned and horsed; he went south with the main part of the invasion force, while some of the invasion force, as well as the hostages, were with his son Cnut. After he came over Watling Street, they went to Oxford, and the town-dwellers soon bowed to him, and gave hostages. From there they went to Winchester, and the people did the same, then eastward to London. But the Londoners put up a strong resistance, because King Æthelred and Thorkell the Tall, a Viking leader who had defected to Æthelred, personally held their ground against him in London itself. Sweyn then went west to Bath, where the western thanes submitted to him and gave hostages. The Londoners then followed suit, fearing Sweyn's revenge if they resisted any longer. King Æthelred sent his sons Edward and Alfred to Normandy, and himself spent Christmas on the Isle of Wight, and then followed them into exile. Based in Gainsborough, Lincolnshire, Sweyn began to organise his vast new kingdom, but he died there on 3 February 1014, having ruled England for only five weeks. Sweyn's cause of death is unknown. Some theorise that he was killed, whereas other sources say he died after falling off a horse. His embalmed body was returned to Denmark for burial in the church he had built. Tradition locates this church in Roskilde, but it is more plausible that it was actually located in Lund in Scania (now part of Sweden). Aftermath Sweyn's elder son, Harald II, succeeded him as King of Denmark, while his younger son, Cnut, was proclaimed King of England by the people of the Danelaw. However, the English nobility sent for Æthelred, who upon his return from exile in Normandy in the spring of 1014 managed to drive Cnut out of England. Cnut soon returned and became king of all England in 1016, following the deaths of Æthelred and his son Edmund Ironside; he succeeded his brother as King of Denmark in
