The far hill in the picture is Lose Hill, which is not too far from Win Hill (you can see the shoulder on the extreme right skyline). This was postulated by W J Andrew about a century ago as having some connection with the Battle of Brunanburgh, the location of which is still uncertain. Various theories put this on the Wirral, around the Humber or anywhere in between. Truth is, nobody knows. The location of the Battle of Brunanburgh is one of history's holy grails given its significance.
However, Andrew's theory could have some merit, as the old Roman road to the north passed close to this point, up from Buxton to Batham Gate and Edale, and we can make a reasonable assumption that the size of both English and Viking armies required the use of existing roads. And it's about a day's quick march to the sea in either direction which would tie in with the Sagas.
