In 865 AD a huge Viking army appeared out of the mists of the North Sea from Scandinavia and landed on the East Anglian coast. Their objective was nothing less than the total conquest of Anglo-Saxon England and the whole of the British Isles. Numbering some 10,000 to 15,000 men the "Great Heathen Army" was the largest invasion force since Roman Legions had landed on the shores of Britannia back in 43 AD. During a 14 year reign of terror they left a brutal trail of destruction in their wake. At its head the army was led by the vengeful sons of the Viking adventurer, Ragnar Lodbrok "Hairy breeches". The mastermind behind the invasion became one of the most feared and cruel warlords of the Viking age, Ivar "the Boneless". His shadow cast a dark cloud over the British Isles that ultimately led to the unification and creation of the nation state of England.
