At the other end of Glyndyfrdwy, passing that pretty, tree-shaded anglers’ house, the “Berwyn Arms,” the hills recede and the valley opens out. The Mail at one time changed here. In those days it was called the “New Inn.” Just before the scenery becomes comparatively homely, two strikingly prominent hills or tumuli, at a short distance from one another, are seen overhanging the Dee. The second of them, standing isolated and crowned with a spindly group of fir trees, is known as “Owain Glyndwr’s Mount,” and there are those among the great Owain’s worshippers who still affect to see the foundations of his house in the rolling meadow beneath. Owain Glyndwr is one of the greatest and latest of Welsh national heroes, and the valley of the Dee is especially linked with his memory. It could scarce be otherwise, for his name of Glyndwr was a territorial one, and derived from his ancestral estate situated here at Glyndyfrdwy and for some miles along the Dee between Berwyn and Corwen. [Illustration: OWAIN GLYNDWR’S MOUNT.] It was in the year 1400 that Owain rose in rebellion and set all Wales aflame against the English. He was no hot-headed patriot, rising for the mere idea of throwing off a foreign yoke, but a man who had suffered wrongs and sought redress in vain. Lord Grey of Ruthin, one of the powerful Lords Marchers, had seized a portion of his land, held it by force of arms, despite the decision of the Courts in London, and represented the injured man to be a rebel who refused the feudal duty of sending help to aid the King against his opening campaign against the Scots. Hitherto he had been no rebel, but a loyal supporter of the English rule, at that time long established firmly in Wales. Not only so, but he had moved in the Court circles of that day, and was not only an educated gentleman, but a personage of wealth, consequence, and influence in his own country, and precisely one to be well treated by politic rulers. Glyndwr was driven into rebellion, if ever man was. He was no youth, but a man of forty-two years of age when matters came to this crisis. He was also one of skill and resource, and, before the provocative Grey could do much, had burnt his town and castle of Ruthin, and, turning towards England, advanced with fire and sword up to the very walls of Shrewsbury. Fortune smiled from that time, first upon one and then upon the other side. English expeditionary forces under the young Prince of Wales drove Glyndwr back, and burnt his ancestral halls at Sycherth and Glyndyfrdwy, and yet when stress of weather warned the English to retreat, Glyndwr, unconquered, was snarling at their heels. Later, he himself assumed the title of Prince of Wales, and in royal manner entered into a tripartite alliance with Hotspur and Mortimer to dethrone Henry IV. and divide England and Wales between them. And had the Battle of Shrewsbury been decided the other way there can be little doubt of their success.
