Nennius says:—"A.D. 452. Then it was that the magnanimous Arthur, with all the kings and military force of Britain, fought against the Saxons. And though there were many more noble than himself, yet he was twelve times chosen their commander, and was as often conqueror." He then informs us that the second, third, fourth, and fifth of these battles were fought on the banks of a "river by the Britons called Duglas, in the region Linuis." Some copies give "Dubglas," which has been identified with the little stream Dunglas, which formed the southern boundary of Lothian. The Rev. John Whitaker, however, contends that the Douglas, in Lancashire, is the stream referred to. He advances, amongst much conjectural matter, the following archæological and traditional details, in support of his position:—
"The name of the river concurs with the tradition, and three battles prove the notice true.[4] On the traditionary scene of this engagement remained till the year 1770 a considerable British barrow, popularly denominated Hasty Knoll. It was originally a vast collection of small stones taken from the bed of the Douglas, and great quantities had been successively carried away by the neighbouring inhabitants. Many fragments of iron had been also occasionally discovered in it, together with the remains of those military weapons which the Britons interred with their heroes at death. On finally levelling the barrow, there was found a cavity in the hungry gravel, immediately under the stones, about seven feet in length, the evident grave of the British officer, and all filled with the loose and blackish earth of his perished remains. At another place, near Wigan, was discovered about the year 1741 a large collection of horse and human bones, and an amazing quantity of horse-shoes, scattered over a large extent of ground—an evidence of some important battle upon the spot. The very appellation of Wigan is a standing memorial of more than one battle at that place.[5] According to tradition, the first battle fought near Blackrode was uncommonly bloody, and the Douglas was crimsoned with blood to Wigan. Tradition and remains concur to evince the fact that a second battle was fought near Wigan Lane, many years before the rencontre in the civil wars. … The defeated Saxons appear to have crossed the hill of Wigan, where another engagement or engagements ensued; and in forming the canal there about the year 1735, the workmen discovered evident indications of a considerable battle on the ground. All along the course of the channel, from the termination of the dock to the point at Poolbridge, from forty to fifty roods in length, and seven or eight yards in breadth, they found the ground everywhere containing the remains of men and horses. In making the excavations, a large old spur, carrying a stem four or five inches in length, and a rowel as large as a half-crown, was dug up; and five or six hundred weight of horse-shoes were collected. The point of land on the south side of the Douglas, which lies immediately fronting the scene of the last engagement, is now denominated the Parson's Meadow; and tradition very loudly reports a battle to have been fought in it."
The rev. historian of Manchester, referring to the statements in Nennius, thus sums up his argument:—
"These four battles were fought upon the river Douglas, and in the region Linuis. In this district was the whole course of the current from its source to the conclusion, and the words, 'Super flumen quod vocatur Duglas, quod est in Linuis,' shows the stream to have been less known than the region. This was therefore considerable; one of the cantreds or great divisions of the Sistuntian kingdom, and comprised, perhaps, the western half of South Lancashire. From its appellation of Linuis or the Lake, it seems to have assumed the denomination from the Mere of Marton," [Martin] "which was once the most considerable object in it."
The Rev. R. W. Morgan, in his "Cambrian History," locates the Arthurian victories as follows:—"1st, at Gloster; 2nd, at Wigan (The Combats), 10 miles from the Mersey. The battle lasted through the night. In A.D. 1780, on cutting through the tunnel, three cart loads of horse-shoes were found and removed; 3rd, at Blackrode; 4th, at Penrith, between the Loder and Elmot, on the spot still called King Arthur's Castle; 5th, on the Douglas, in Douglas Vale; 6th, at Lincoln; 7th, on the edge of the Forest of Celidon (Ettrick Forest) at Melrose; 8th, at Cær Gwynion; 9th, between Edinburgh and Leith; 10th, at Dumbarton; 11th, at Brixham, Torbay; 12th, at Mont Baden, above Bath."
Geoffrey of Monmouth refers but to one battle on the banks of the "Duglas." This he fixes at about the year 500. He tells us that "the Saxons had invited over their countrymen from Germany, and, under the command of Colgrin, were attempting to exterminate the whole British race. … Hereupon, assembling the youth under his command, he marched to" [towards] "York, of which when Colgrin had intelligence, he met him with a very great army, composed of Saxons, Scots, and Picts, by the river Duglas, where a battle happened, with the loss of the greater part of both armies. Notwithstanding, the victory fell to Arthur, who pursued Colgrin to York, and there besieged him."
Mr. Daniel H. Haigh, one of the latest advocates of the genuine historical veracity which underlies much of the Arthurian traditions, places, as we have previously observed, Arthur's coronation A.D. 467, or about 32 years earlier than the usually received date. He says—"The river Douglas, which falls into the estuary of the Ribble, is certainly that which is indicated here;" [the second, third, fourth, and fifth victories referred to by Nennius] "and although it was one of Arthur's tactics to
