During the remainder of this reign the Gentile war resumed much of its old local and guerrilla character, the Provincial chiefs, and the Ard-Righ, occasionally employing bands of one nation of the invaders to combat the other, and even to suppress their native rivals. The only pitched battle of which we hear is that of "the Two Plains" (near Coolestown, King's County), in the second last year of Malachy (A.D. 859), in which his usual good fortune attended the king. The greater part of his reign was occupied, as always must be the case with the founder of a new line, in coercing into obedience his former peers. On this business he made two expeditions into Munster, and took hostages from all the tribes of the Eugenian race. With the same object he held a conference with all the chiefs of Ulster, Hugh of Aileach only being absent, at Armagh, in the fourth year of his reign, and a General _Feis_, or Assembly of all the Orders of Ireland, at Rathugh, in West-Meath, in his thirteenth year (A.D. 857). He found, notwithstanding his victories and his early popularity, that there are always those ready to turn from the setting to the rising sun, and towards the end of his reign he was obliged to defend his camp, near Armagh, by force, from a night assault of the discontented Prince of Aileach; who also ravaged his patrimony, almost at the moment he lay on his death-bed. Malachy I. departed this life on the 13th day of November, (A.D. 860), having reigned sixteen years. "Mournful is the news to the Gael!" exclaims the elegiac Bard! "Red wine is spilled into the valley! Erin's monarch has died!" And the lament contrasts his stately form as "he rode the white stallion," with the striking reverse when, "his only horse this day"—that is the bier on which his body was borne to the churchyard—"is drawn behind two oxen." The restless Prince of Aileach now succeeded as Hugh VII., and possessed the perilous honour he so much coveted for sixteen years, the same span that had been allotted to his predecessor. The beginning of this reign was remarkable for the novel design of the Danes, who marched out in great force, and set themselves busily to breaking open the ancient mounds in the cemetery of the Pagan kings, beside the Boyne, in hope of finding buried treasure. The three Earls, Olaf, Sitrick, and Ivar, are said to have been present, while their gold-hunters broke into in succession the mound-covered cave of the wife of Goban, at Drogheda, the cave of "the Shepherd of Elcmar," at Dowth, the cave of the field of Aldai, at New Grange, and the similar cave at Knowth. What they found in these huge cairns of the old _Tuatha_ is not related; but Roman coins of Valentinian and Theodosius, and torques and armlets of gold, have been discovered by accident within their precincts, and an enlightened modern curiosity has not explored them in vain, in the higher interests of history and science.
