Andhun was an Ealdorman of Sussex under King Æðelwealh, who was slain by the Wessex prince Cædwalla, who invaded and ravaged Sussex.[1] Berhthun and Andhun succeeded in driving Caedwalla from the Kingdom.[2]
In 686, the South Saxons attacked Hlothhere, King of Kent, in support of his nephew Eadric, but soon after Berhthun was killed and the kingdom subjugated for a time by Caedwalla, who had now become King of Wessex.[3]
