|Battle of Beran Byrig|
|Part of the Anglo-Saxon settlement of Britain|
|Commanders and leaders|
At the Battle of Beran Byrig or Beranburh the West Saxons are said to have defeated the Britons at Barbury Castle Hill Fort near Swindon in the year 556.
The Anglo-Saxon Chronicle entry for the year states: Her Cynric 7 Ceawlin fuhton wiþ Brettas æt Beranbyrg (This year Cynric and Ceawlin fought with the Britons at Beranbury).
Control of Barbury Castle is likely to have been important as it lies on The Ridgeway, a strategic communication route.
