The Anglo-Saxon Chronicle records a battle fought in the year 715 at Woden's Burg, the neolithic long barrow now known as Adam's Grave, near Marlborough, Wiltshire.
The entry states: "Her Ine 7 Ceolred fuhton æt Woddes beorge."
(There Ine and Ceolred fought at Woden's hill.)
[1] The Anglo-Saxon Chronicle also records an earlier battle on the same site.
The area was of strategic importance since it lay near the intersection of the ancient Ridgeway with Wansdyke.
