Statue of Alfred the Great at Winchester
In 878 King Alfred of Wessex defeated a Viking army at the Battle of Edington. Guthrum, the Viking leader, retreated with the remnants of his army to their "stronghold", where Alfred besieged him. After fourteen days the Vikings "thoroughly terrified by hunger, cold and fear" sought peace and sent an emissary to Alfred.
Alfred accepted Guthrum's surrender. According to Asser, in his Life of Alfred, the Vikings gave Alfred peace hostages, and "swore in addition that they would leave his kingdom immediately, and Guthrum, their king, promised to accept Christianity and to receive baptism at King Alfred's hand; all of which he and his men fulfilled as they had promised."
Three weeks later Guthrum and thirty of his men came to Alfred at Aller, near Athelney, and there Guthrum was baptised, with Alfred accepting him as his adoptive son. Then, according to Asser:
- the unbinding of the chrisom on the eighth day took place at a royal estate called Wedmore.
As agreed Guthrum left Chippenham and moved to Cirencester. Following this Guthrum returned to East Anglia, where he ruled in what had been East Anglia, Essex and Eastern Mercia. Over time these lands became known as Danelaw. Eventually Wessex, under Alfred and his successors, conquered all of this land.
