[A.D. 926-1022.] Many of the sea-coast towns were now in possession of the Danes. They had founded Limerick, and, indeed, Wexford and Waterford almost owe them the debt of parentage. Obviously, the ports were their grand securities--a ready refuge if driven by native valour to embark in their fleets; convenient head-quarters when marauding expeditions to England or Scotland were in preparation. But the Danes never obtained the same power in Ireland as in the sister country. The domestic dissensions of the men of Erinn, ruinous as they were to the nation, gave it at least the advantage of having a brave and resolute body of men always in arms, and ready to face the foe at a moment's notice, when no selfish policy interfered. In 937 Athelstane gained his famous victory over the Danes at Brunanbriegh in Northumberland, and came triumphantly to reclaim the dagger[208] which he had left at the shrine of St. John of Beverley. After his death, in 941, Amlaff returned to Northumberland, and once more restored the Danish sway. From this time, until the accession of the Danish King Canute, England was more or less under the dominion of these ruthless tyrants.[209]
