Mr. J. R. Green ("The Making of England") traces Ethelfrith's march through Lancashire to his victory at Bangor-Iscoed. He says--"Though the deep indent in the Yorkshire shire-line to the west proves how vigorously the Deirans had pushed up the river valleys into the moors, it shows that they had been arrested by the pass at the head of the Ribblesdale; while further to the south the Roman road that crossed the moors from York to Manchester was blocked by the unconquered fastnesses of Elmet, which reached away to the yet more difficult fastnesses of the Peak. But the line of defence was broken as the forces of Ethelfrith pushed over the moors along the Ribblesdale into our southern Lancashire. His march was upon Chester, the capital of Gwynedd, and probably the refuge place of Edwine."
The more northern portion of the county was not subdued till about half a century afterwards, when Cumberland and Westmoreland were absorbed into the Northumbrian kingdom by Ecfrith (670-685). Mr. J. R. Green, in the work referred to, says--"The Welsh states across the western moors had owned, at least from Oswald's time, the Northumbrian supremacy, but little actual advance had been made by the English in this quarter since the victory of Chester, and northward of the Ribble the land between the moors and the sea still formed a part of the British kingdom of Cumbria. It was from this tract, from what we now know as northern Lancashire and the Lake District, Ecgfrith's armies chased the Britons in the early years of his reign."
Some severe struggles must have taken place during this period; and, therefore, it is by no means improbable that a portion, at least, of the remains on the banks of the Douglas, referred to by the Rev. John Whitaker as evidence of Arthur's historical existence, may pertain to the struggles of the Brit-Welsh and their Angle or English conquerors of the seventh century. This confusion of names and dates is a common feature in the folk-lore of all nations and periods, but in none is it more strongly developed than in the Arthurian romances. The author of the metrical "Morte D'Arthur," after describing the victory of the hero over his rebellious nephew, Modred, at "Barren-down," near Canterbury, tells us that the barrows raised on the burial of the slain were still to be seen in his day. Barham Down is still covered with barrows, which recent examination has demonstrated to be the remains of a Saxon cemetery, and not a battle-field.
