But the Irish did not always fly in dismay, as was the case in England and France. A force was generally mustered in the neighborhood to meet and repel the attack, and in numerous instances the marauders were driven back with slaughter to their ships.
For the clans rallied to the defence of the Church. Though the chieftains and their clansmen might seem to have failed fully to imbibe the spirit of religion, though in their insane feuds they often turned a deaf ear to the remonstrances and reproaches of the bishops and monks, nevertheless Christianity reigned supreme in their inmost hearts. And when they beheld pagans landed on their shores, to insult their faith and destroy the monuments of their religion, to shed the blood of holy men, of consecrated virgins, and of innocent children, they turned that bravery which they had so often used against themselves and for the satisfaction of worthless contentions into a new and a more fitting channel—the defence of their altars and the punishment of sacrilegious outrage.
The clan system was the very best adapted for this kind of warfare, so long as no large fleets came, and the pirates were too few in number and too sagacious in mind to think of venturing far inland. When but a small number of boats arrived, the invaders found in the neighborhood a clan ready to receive them. The clansmen speedily assembled, and, falling on the plundering crews, showed them how different were the free men of a Celtic coast, who were inspired by a genuine love for their faith, from the degenerate sons of the Gallo-Romans.
So the annals of the country tell us that the "foreigners" were destroyed in 812 by the men of Umhall in Mayo; by Corrach, lord of Killarney, in the same year; by the men of Ulidia and by Carbry with the men of Hy-Kinsella in 827; by the clansmen of Hy- Figeinte, near Limerick, in 834, and many more.
But the hydra had a thousand heads, and new expeditions were continually arriving. In the words of Mr. Worsaae, a Danish writer of this century:
"From time immemorial Ireland was celebrated in the Scandinavian north, for its charming situation, its mild climate, and its fertility and beauty. The Kongspell—mirror of Kings—which was compiled in Norway about the year 1200, says that Ireland is almost the best of the lands we are acquainted with although no vines grow there. The Scandinavian Vikings and emigrants, who often contented themselves with such poor countries as Greenland and the islands in the north Atlantic, must, therefore, have especially turned their attention to the 'Emerald Isle,' particularly as it bordered closely upon their colonies in England and Scotland. But to make conquests in Ireland, and to acquire by the sword alone permanent settlements there, was no easy task…. When we consider that neither the Romans nor the Anglo-Saxons ever obtained a footing in that country, although they had conquered England, the adjacent isle, and when we further reflect upon the immense power exerted by the English in later times in order to subdue the Celtic population of the island, we cannot help being surprised at the very considerable Scandinavian settlements which, as early as the ninth century, were formed in that country."
These are the words of a Dane. We shall see what the "very considerable Scandinavian settlements" amounted to; the quotation is worthy of note, as presenting in a few words the motives of those who at any time invaded Ireland, and the stubborn resistance which they met.
The Irish were not dismayed by the constant arrivals of those northern hordes. They met them one after another without considering their complexity and connection. They only saw a troop of fierce barbarians landed on their shores, chiefly intent upon plundering and burning the churches and holy houses which they had erected; they saw their island, hitherto protected by the ocean from foreign attack, and resting in the enjoyment of a constant round of Christian festivals and joyful feasts, now desecrated by the presence and the fury of ferocious pagans; they armed for the defence of all that is dear to man; and though, perhaps, at first beaten and driven back, they mustered in force at a distance to fall on the victors with a swoop of noble birds who fly to the defence of their young.
This kind of contest continued for two hundred years, with the exception of the periods of larger invasions, when a single clan no longer sufficed to avenge the cause of God and humanity, and the Ard-Righ was compelled to throw himself on the scene at the head of the whole collective force of the nation in order to oppose the vast fleets and large armies of the Danes.
The country suffered undoubtedly; the cattle were slain; the fields devastated; the churches and houses burned; the poets silenced or woke their song only to notes of woe; the harpers taught the national instrument the music of sadness; the numerous schools were scattered, though never destroyed; as centuries later, under the Saxon, the people took their books or writing materials to their miserable cottages or hid them in the mountain fastnesses, and thus, for the first time in their history, the hedge school succeeded those of the large monasteries. So the nation continued to live on, the energetic fire which burned in the hearts of the people could not be quenched. They rose and rose again, and often took a noble revenge, never disheartened by the most utter disaster.
