556: Beran Byrg
The first record of a battle fought by Ceawlin is in 556, when he and his father, Cynric, fought the native Britons at "Beran byrg", or Bera's Stronghold. This now is identified as Barbury Castle, an Iron Age hill fort in Wiltshire, near Swindon. Cynric would have been king of Wessex at this time.
