On three different occasions this bloody strife assumed a yet more serious and dangerous aspect. It was not a few boats only which came to the shores of the devoted island; but the main power of Scandinavia seemed to combine in order to crush all opposition at a single blow.
When the knowledge of the richness, fertility, and beauty of the island had fully spread throughout Denmark and Norway, a large fleet gathered in the harbors of the Baltic and put to sea. The famous Turgesius or Turgeis—Thorgyl in the Norse—was the leader. The Edda and Sagas of Norway and Denmark have been examined with a view to elucidate this passage in Irish history, but thus far fruitlessly. It is known, however, that many Sagas have been lost which might have contained an account of it. The Irish annals are too unanimous on the subject to leave any possibility of doubt with regard to it; and, whatever may be the opinion of learned men on the early events in the history of Erin, the story of the eighth, ninth, and tenth centuries rests entirely on historical ground, as surely as if the facts had happened a few hundred years ago.
Turgesius landed with his fleet on the northeast coast of the island, and straightway the scattered bands of Scandinavians already in the country acknowledged his leadership and flocked to his standard. McGeoghegan says that "he assumed in his own hands the sovereignty of all the foreigners that were then in Ireland."
From the north he marched southward; and, passing Armagh on his route, attacked and took it, and plundered its shrines, monasteries, and schools. There were then within its walls seven thousand students, according to an ancient roll which Keating says has been discovered at Oxford. These were slaughtered or dispersed, and the same fate attended the nine hundred monks residing in its monasteries.
Foraanan, the primate, fled; and the pagan sea-kong, entering the cathedral, seated himself on the primatial throne, and had himself proclaimed archbishop.—(O'Curry.) He had shortly before devastated Clonmacnoise and made his wife supreme head of that great ecclesiastical centre, celebrated for its many convents of holy women. The tendency to add insult to outrage, when the object of the outrage is the religion of Christ, is old in the blood of the northern barbarians; and Turgesius was merely setting the example, in his own rude and honest fashion, to the more polished but no less ridiculous assumption of ecclesiastical authority, which was to be witnessed in England, on the part of Henry VIII. and Elizabeth.
The power of the invader was so superior to whatever forces the neighboring Irish clans could muster, that no opposition was even attempted at first by the indignant witnesses of those sacrileges. It is even said that at the very time when the Northmen were pillaging and burning in the northeast of the island, the men of Munster were similarly employed in Bregia; and Conor, the reigning monarch of Ireland, instead of defending the invaded territories, was himself hard at work plundering Leinster to the banks of the river Liffey—(Haverty.) But, doubtless, none of those deluded Irish princes had yet heard of the pagan devastations and insults to their religion, and thus it was easy for the great sea-kong to strengthen and extend his power. For the attainment of his object he employed two powerful agents which would have effectually crushed Ireland forever, if the springs of vitality in the nation had not been more than usually expansive and strong.
The political ability of the Danes began to show itself in Ireland, as it did about the same period (830) in England, and later on in France. Turgesius saw that, in order to subdue the nation, it was necessary to establish military stations in the interior and fortify cities on the coast, where he could receive reinforcements from Scandinavia. These plans he was prompt to put into practice.
His military stations would have been too easily destroyed by the bravery of the Irish, strengthened by the elasticity of their clan-system, if they were, planted on land. He, therefore, set them in the interior lakes which are so numerous in the island, where his navy could repel all the attacks of the natives, unused as they were to naval conflicts. He stationed a part of his fleet on Lough Lee in the upper Shannon, another in Lough Neagh, south of Antrim, a third in Lough Lughmagh or Dundalk bay. These various military positions were strongholds which secured the supremacy of the Scandinavians in the north of the island for a long time. In the south, Turgesius relied on the various cities which his troops were successively to build or enlarge, namely, Dublin, Limerick, Galway, Cork, Waterford, and Wexford. This first Scandinavian ruler could begin that policy only by establishing his countrymen in Dublin, which they seized in 836.
Up to that time the Irish had scarcely any city worthy of the name. A patriarchal people, they followed the mode of life of the old Eastern patriarchs, who abhorred dwelling in large towns. Until the invasion of the Danes, the island was covered with farm-houses placed at some distance from each other. Here and there large duns or raths, as they were called, formed the dwellings of their chieftains, and became places of refuge for the clansmen in time of danger. Churches and monasteries arose in great numbers from the time of St. Patrick, which were first built in the woods, but soon grew into centres of population, corresponding in many respects to the idea of towns as generally understood.
The Northmen brought with them into Ireland the ideas of cities, commerce, and municipal life, hitherto unknown. The introduction of these supposed a total change necessary in the customs of the natives, and stringent regulations to which the people could not but be radically opposed. And strange was their manner of introduction by these northern hordes. Keating tells us how Turgesius understood them. They were far worse than the imaginary laws of the Athenians as recorded in the "Birds" of Aristophanes. No more stringent rules could be devised, whether for municipal, rural, or social regulations; and, as the Northmen are known to have been of a systematic mind, no stronger proof of this fact could be given.
