warriors were the dominant force. The víkingar were ‘the men from the fjords’. They came because their own territories were unsettled by the emergence of new and centralized kingdoms; these kingdoms in turn encouraged the formation of warrior bands ready to kill and pillage. The land of Denmark was also being threatened by Charlemagne, king of the Frankish Empire, further undermining the powers of the ruling elite. It takes only one moment of fear to launch a hundred ships. This was the period, too, when the design of the longboat was perfected. The wind was literally in the sails of the Norsemen. Another cause can be found for these bloody expeditions. The monasteries of Lindisfarne and Jarrow were not attacked at random; they were chosen as examples of revenge. The onslaught of the Christian Charlemagne on the ‘pagans’ of the north had led to the extirpation of their shrines and sanctuaries. The great king had cut down Jôrmunr, the holy tree of the Norse people. What better form of retaliation than to lay waste the foundations devoted to the Christian God? The Christian missionaries to Norway had in fact set out from Lindisfarne. So its destruction was nicely calculated. It was the beginning of what might be called an anti-Christian crusade. In the year the monastery burned, premonitions passed across the tremulous English sky. The Anglo-Saxon Chronicle records that in 793 ‘terrible omens appeared over the Northumbriansand miserably distressed the people: there were immense lightning flashes, and fiery dragons were seen flying in the sky’. Yet these early raids were really only a warning, a seismic shudder before the fire burst forth. The English people were becoming more nervous, and the archaeological evidence suggests that more of them chose the safety of the walled towns. The earliest monastic chronicle was written at this time, to be incorporated later into the first version of the Anglo-Saxon Chronicle . The hand of the monk may have been guided by a sense that the world was changing for the worse. In 830 the raids began once more. The forces of ‘heathen men’ had come for land and slaves and women. They fell upon the island of Sheppey, off the coast of North Kent, in 833. As its name implies, it was filled with sheep and good pasture. That was the prize. The Norsemen were well known for their skills in stock-breeding. Over the next thirty years a score of other attacks took place, from the men of Denmark in particular. Kent and East Anglia were an attractive target; the first sea battle in English history took place off Sandwich, in Kent, when the invaders were rebuffed. But the port at Southampton was ravaged by them. London and Rochester were attacked. The army of Northumberland was defeated in battle. The threat came from all sides. Some of the warriors were known as ‘wolf-coats’ from their mode of dress and from the howls they sent up in battle. They brandished long kite-like shields, and wielded ferocious battleaxes against their prey. Others were known as ‘berserks’ because they wore no armour and charged the enemy in the throes of blood frenzy. The sagas tell of one warrior known as ‘the children’s man’; unlike his companions, he refused to impale children on the tip of his lance. These men were the terror of England. The raids were simply the prelude to a true invasion. In 865 a great host of Danes descended upon East Anglia. This was the region their ancestors knew best and where many of them already lived. These men had not come to raid; they had come to settle. It is no coincidence that in this period there was a marked increase in the population of Scandinavia, where land was becoming more scarce. They came in their thousands, aboard hundreds of ships; eachship could carry no more than thirty men. They dwelled in East Anglia for twelve months, taking command of the local resources and in particular marshalling a regiment of good horses. They established fortresses, or
