From the position of the battle-field it has been made out to their own satisfaction by those who have studied it on the spot, that the Firbolgs must have taken up a fortified position upon the hill called Ben-levi; a good strategic position unquestionably, having behind it the whole of the Mayo mountains into which to retreat in case of defeat. The Danaans, on the other hand, advancing from the plains of Meath, took up their station upon the hill known as Knockmaa[1], standing by itself about five miles from the present town of Tuam, on the top of which stands a great cairn, believed to have been in existence even then--a legacy of some yet earlier and more primitive race which inhabited the country, and, therefore, possibly the oldest record of humanity to-day extant in Ireland. [1] Now Castle Hacket Hill. Three days the battle is said to have raged with varying fortunes, in the course of which the Danaan king Nuad lost his arm, a loss which was repaired, we are told, by the famous artificer Credue or Cerd, who made him a silver one, and as "Nuad of the Silver Hand" he figures conspicuously in early Irish history. In spite of this, and of the death of a number of their fighting-men, the stars fought for the Tuatha-da-Danaans, who were strong men and cunning, workers in metal, and great fighters, so that at last they utterly made an end of their antagonists, occupying the whole country, and holding it, say the annalists for a hundred and ninety and six years--building earth and stone forts, many of which exist to this day, but what their end was no man can tell you, save that they, too, were, in their turn, conquered by the Milesians or "Scoti," who next overran the country, giving to it their own name of Scotia, by which name it was known down to the end of the twelfth century, and driving the earlier settlers before them, who thereupon fled to the hills, and took refuge in the forests, whence they emerged, doubtless, with unpleasant effect upon their conquerors, as another defeated race did upon _their_ conquerors in later days.
