Cnut the great leading an army
Totally unexpected Sweyn Forkbeard became very ill(He was probably suffering from a hereditary heart disease) and on the 3. February he died in his headquarter at Gainsborough. With his neglected wife Gunhild, he had 2 sons. The oldest son, Harald 2 was crowned king of Denmark, Harald 2 had been the ruler of Denmark while Sweyn Forkbeard was in England. The youngest, 17 year old Cnut the great was given the royal scepter and took command of the viking army in England.

When the Anglo-Saxons heard that the feared Sweyn Forkbeard was dead, they called Ethelred the unready home to England from his refuge in Normandy and his son Edmund Ironside now led an army prepared to fight the Danish again. Cnut the great had to leave England fast, but before he sailed back to Denmark, he cut of nose,ears and hands of Sweyn Forkbeards hostages in Sandwich. He swore that he would return to England again. Thorkil the tall broke with king Ethelred the unready and sailed to Denmark where he joined Cnut the great.
