If we must go so far north, I would rather feel inclined to place it at Wood Castle, near Lochmaben, in Dumfriesshire, where there is a circular enclosure identical in plan and dimensions with King Arthur's Round Table at Penrith.[162] Strategically, it is a much more likely spot than the exposed east coast of Northumberland; but, except the plan of Wood Castle, I know of no authority for placing this battle-field in Annandale. There is no indication where the second, third, or fourth battles were fought; but for the fifth we have this important designation that it was fought "super aliud flumen quod vocatur Duglas vel Dubglas quod est in regione Linuis," or in another MS. Linnuis. A marginal note suggests Lindesay, in Lincolnshire, but for no other reason apparently than from the first three letters being the same in both. There is a River Duglas flowing past Wigan, in Lancashire, which Whittaker, in his 'History of Manchester,' boldly adopts as the place indicated, and others have been inclined to accept his determination. After going carefully over the ground, I confess no spot appears to me more unlikely for a great battle than the banks of this river, nor does any local evidence of their having been so now remain. One cannot but feel that if Arthur ever allowed himself to be pushed into such a corner, with nothing but the sea behind him to retreat upon, he certainly was not the general that made so successful a stand against the Saxons. I am much more inclined to believe that Linnuis is only a barbarous latinization of Linn, which in Gaelic and Irish means sea or lake. In Welsh it is Lyn, and in Anglo-Saxon Lin, and if this is so, "In regione Linnuis" may mean "In the Lake Country." The name of the river does not appear to me at all an insuperable difficulty. All the rivers about Penrith, the Lowther, the Eamount, and the Eden, have names that were certainly given to them by the Saxons, but they must have had Celtic names before they came; and Dubh as an adjective is dark or black, and Glas, green or grey, is used as a substantive to denote the sea, in Irish. Such an epithet would apply admirably to the Lowther; and if it could be identified with the river mentioned by Nennius, our difficulties would be at an end. These speculations, however, must of course be taken for what they are worth. There is, so far as known, no authority for the name Duglas or Dubhglas being applied to the Lowther or Eden. The sixth battle was on a river called Bassas. It has been suggested that this means the Bass Rock in the Frith of Forth; but it need hardly be objected that a rock is not a river, and there is an extreme improbability that Arthur ever saw the Lothians. In Derbyshire there is a Bas Lowe[163] in a neighbourhood where, as we shall presently see, there is reason to believe Arthur fought one or more of his battles, but I am not aware of any river so called in that neighbourhood.
