"The evidence which is wanting with regard to Arthur's battle on the Camel comes to light on the Firth of Forth. There is reason to suppose that tradition did not err in the fatal association of Arthur and Mordred, though the place of the last scene was not Cornwall but Scotland. The name Camlan which has been freely given by later writers to the supposed battle on the Camel, is not to be found there, nor, so far as I can ascertain, in Cornwall. "Skene and Stuart Glennie maintain with much converging evidence that Camlan is Camelon on the river Carron in the valley of the Forth, where it is said are the remains of a Roman town. Here, according to Scotch tradition Arthur and Mordred met. We have evidence which appears to be sufficient that Mordred was King of the Picts, or, as he is sometimes termed, King of Scotland, and the head of a confederacy of Picts, Scots and Saxons, or, as some authorities have it of Picts, Scots and renegade Britons. With this composite army he gave battle to Arthur and his faithful British force, in which the latter were defeated and Arthur slain. "It is worth noting as in favour of the Scottish location of the battle that Geoffrey [of Monmouth] who places it on the Camel states Mordred's force to have consisted of Picts and Scots. It is surely improbable that Arthur could have been confronted in Cornwall by a great army of these northern savages.... It may be added that an earthwork with double lines of circumvallation in the neighbouring valley of the Tay now known as Barry Hill, is designated by tradition as Mordred's castle."
