Battle of Alclud Ford
The Battle of Alclud Ford was a battle between the post-Roman Celtic Britons of Rheged and the Anglo-Saxon Kingdom of Bernicia around c. 580CE. The fighting may have taken place at an unknown ford near Alt Clut, the original name for Dumbarton Rock, which may also be used for the entire ancient Kingdom of Strathclyde. The battle is recorded in two poems in the Book of Taliesin.
