When Ambrosius Aurelianus and Uther Pendragon killed Vortigen and stole his throne, Merlin appeared to change his allegiance and support Ambrosius until his death, and then Uther when he succeeded him.
It supposedly was the site of a battle between certain Vitalinus, possibly Vortigern, and Aurelius Ambrosius.
