Ferchar-fada, or the _tall_, apparently of the race of Lorn, and either the son or grandson of Ferchar, who died in 637, seized the reins of government upon the death of Maolduin. On the death of Ferchar, in 702, the sceptre passed again to the Fergusian race in the person of Eocha’-rineval, remarkable for his Roman nose, the son of Domangart. The reign of this prince was short and unfortunate. His sceptre was seized by Ainbhcealach, the son of Ferchar-fada, who succeeded Eocha’ in 705. He was of an excellent disposition, but after reigning one year, was dethroned by his brother, Selvach, and obliged, in 706, to take refuge in Ireland. Selvach attacked the Britons of Strathcluyd, and gained two successive victories over them, the one at Longecoleth in 710, and the other at the rock of Mionuirc in 716. At the end of twelve years, Ainbhcealach returned from Ireland, to regain a sceptre which his brother had by his cruelties shown himself unworthy to wield, but he perished in the battle of Finglein, perhaps Glen Fyne at the head of Loch Fyne, in 719. Selvach met a more formidable rival in Duncha-beg, who was descended from Fergus, by the line of Congal; he assumed the government of Cantyre and Argail, and confined Selvach to his family settlement of Lorn. These two princes appear to have been fairly matched in disposition and valour, and both exerted themselves for the destruction of one another, thus bringing many miseries upon their tribes. In an attempt which they made to invade the territories of each other in 719 by means of currachs, a naval combat ensued off Airdeanesbi, (probably Ardaness on the coast of Argyle,) in which Selvach was overcome by Duncha; but Selvach was not subdued. The death of Duncha in 721 put an end to his designs; but Eocha’ III., the son of Eocha’-rineval, the successor of Duncha, being as bent on the overthrow of Selvach as his predecessor, continued the war. The rival chiefs met at Irroisfoichne in 727, where a battle was fought, which produced nothing but irritation and distress. This lamentable state of things was put an end to by the death of Selvach in 729. This event enabled Eocha to assume the government of Lorn, and thus the Dalriadan kingdom which had been alternately ruled by chiefs of the houses of Fergus and Lorn became again united under Eocha. He died in 733, after a reign of thirteen years, during nine of which he ruled over Cantyre and Argyle, and four over all the Dalriadic tribes.
