Brunanburh fought in Scotland rather than England

The Scottish newspaper The Herald reports that the tenth-century Battle of Brunanburh was fought in Scotland rather than in England.

The battle which historians regard as England's greatest may have been fought on Scottish soil, it is claimed.
The location of the tenth-century battle of Brunanburh has long been considered one of history's greatest unsolved mysteries.
It was there that Athelstan, grandson of Alfred the Great, destroyed the combined armies of the Scottish king, Causantin mac Aeda, Owain, king of Strathclyde, and the Viking king of Dublin, Anlaf Guthfrithson, to confirm his supremacy over the land.
However, research shows that the site of the bloody battle of Brunanburh was in Dumfriesshire and not in England, as most accounts of the battle have proposed.
