Arrived on the coast they had determined to ravage, they soon found that in stormy weather they were in a more dangerous position than at sea. Hence they looked for a deep bay, or, better still, the mouth of a large river, and once on its placid bosom they felt themselves masters of the whole country. The terror of the people, the lack of organization for defence, so characteristic of Celtic or purely Germano-Franco society, the savage bravery and reckless impetuosity of the invaders themselves, increased their rashness, and urged them to enter fearlessly into the very heart of a country which lay prostrate with fear before them. All the cities on the river-banks were plundered as they passed, people of whatever age, sex, or condition, were murdered; the churches especially were despoiled of their riches, and the numerous and wealthy monasteries then existing were given to the flames, after the monks and all the inmates even to the schoolchildren, had been promiscuously slaughtered, if they had not escaped by flight. But, although all were slaughtered promiscuously, a special ferocity was always displayed by the barbarous conqueror toward the unarmed and defenceless ministers of religion. They took a particular delight in their case in adding insult to cruelty; and not without reason did the Church at that time consider as martyrs the priests and monks who were slain by the pagan Scandinavians. Their sanguinary and hideous idolatry showed its hatred of truth and holiness in always manifesting a peculiar atrocity when coming in contact with the Church of Christ and her ministers. And, our chief object in speaking of the stand made by the Irish against the pagan Danes is, to show how the clan-system became in truth the avenger of God's altars and the preserver of the sacred edifices and numerous temples with which, as we have seen, the Island of Saints was so profusely studded, from total annihilation. Knowing that, when their march of destruction had taken them a great distance from the mouth of the river, the inhabitants might rise in sheer despair and cut them off on their return, the Scandinavian pirates, to guard against such a contingency, looked for some island or projecting rock, difficult of access, which they fortified, and, placing there the plunder which loaded their boats, they left a portion of their forces to guard it, while the remainder continued their route of depredation. In Ireland they found spots admirably adapted for their purpose in the numerous loughs into which many of the rivers run.
