Resumen:
The article discusses the Battle of Chester fought in Northumbria, England between the English forces of Northumbria led by King Æthelfrith against the Britons of Wales dated alternately to 613 or 615. It considers the battle's conflicted historiography in accounts written by historians including Geoffrey of Monmouth, Charles Edwards, and Theophilus Evans.
