Assandun (Danish Invasion).

The last of the five battles fought in 1016 between the English under Edmund Ironside and the Danish invaders under Knut. Owing to the treachery of Ædric, who crossed over with the Hereford men in the course of the battle, the English were defeated, and shortly afterwards Knut was proclaimed King of England.
