Not long after the battle, in May 878, King Alfred left the Somerset marshes and defeated Guthrum's forces at the Battle of Edington. He then pursued the Danes to their stronghold at Chippenham and starved them into submission. One of the terms of the surrender was that Guthrum convert to Christianity. Three weeks later the Danish king and 29 of his chief men were baptised at Alfred's court at Aller, near Athelney, with Alfred receiving Guthrum as his spiritual son.
