[Sidenote: Battle of Ardderyd.] These dissensions now broke into open rupture, and a great battle is recorded to have taken place between them in the year 573, which was to decide who was to have the mastery. It was termed the battle of Ardderyd, and the scene of it was at Arthuret, situated on a raised platform on the west side of the river Esk, about eight miles north of Carlisle. This name is simply the modern form of the word Ardderyd. Two small hills here are called the Arthuret knowes, and the top of the highest, which overhangs the river, is fortified by an earthen rampart. About four miles north of this is a stream which flows into the Esk, and bears the name of Carwhinelow, in which the name of Gwendolew can be easily recognised; and near the junction of the Esk and the Liddel, at no great distance from it, is the magnificent hill-fort called the Moat of Liddel. Here this great battle was fought, the centre of a group of Welsh traditions.[176] It resulted in the victory of the Christian party and the establishment of Rhydderch as the king of the Cumbrian Britons. We find him mentioned in Adamnan’s Life of Saint Columba as reigning at Alclyde or Dumbarton, and from the seat of his capital his kingdom came to be called Strathclyde. Adamnan tells us that Rodercus, son of Tothail, who reigned at the Rock of Cluaithe (Petra Cloithe, Alclyde, or Dumbarton), being on friendly terms with St. Columba, sent him a message to ask him whether he would be killed by his enemies or not, and the saint replied that he would never be delivered into the hands of his enemies, but die at home on his own pillow; which prophecy, adds Adamnan, regarding King Roderic, was fully accomplished, for, according to his word, he died quietly in his own house.[177] Adamnan was born only twenty-one years after the death of Rhydderch. The next brother who reigned over Bernicia was Freodulf, for six years, but no war is recorded in his reign; but that of his successor Theodoric, who reigned from 580 to 587, introduces us to a new champion for the Britons, Urbgen, the City-born—the Urien of the Bards—who, with his sons, is said to have fought stoutly against him; and it is added that sometimes the enemy and sometimes the natives prevailed. This Theodoric is the Flamddwyn or Flame-bearer of the Bards.[178] He was succeeded by the last of the brothers who reigned, Aethelric, who, after a short reign of two years, was followed in 594 by his son Ethelfred Flesaurs, of whom Bede tells us that he was a most powerful king and covetous of glory, who more than all the chiefs of the Angles ravaged the nation of the Britons. For no one among the tribunes, no one among the kings, after exterminating or subjugating the natives, caused a greater extent of their territory to become either tributary to the nation of the Angles or to be colonised by them.[179]
