At least 300 nobles The Battle of Catraeth was fought around AD 600 between a force raised by the Gododdin, a Brythonic people of the Hen Ogledd or "Old North" of Britain, and the Angles of Bernicia and Deira.
In his Canu Aneirin Ifor Williams interpreted mynydawc mwynvawr in the text of Y Gododdin to refer to a person, Mynyddog Mwynfawr in modern Welsh.
He feasted them at Din Eidyn for a year, preparing for battle, then launched an attack on Catraeth, which Williams agrees with Thomas Stephens in identifying as Catterick in North Yorkshire, which was in Anglo-Saxon hands.
Rosemary Sutcliff's young adult novel The Shining Company (1990) tells the story of the Battle of Catraeth from the viewpoint of Prosper, shield-bearer to one of King Mynyddog's Gododdin warriors.
Richard J. Denning's 2010 novel, The Amber Treasure tells the story of the Battle of Catraeth from the point of view of a young Anglo Saxon youth, Cerdic.
