nes in the Irish Sea and Strangford Lough. p align="justify"> In 860 the Vikings of Waterford attacked the King of Israige but were slaughtered and attacks on the Vikings in Ireland increased. In 866 the settlement longphort was destroyed and the King of Northern UГ NГ©ill managed to rid the Vikings from Ulster. Connachtmen in 887 slaughtered the Vikings of Limerick and in 892 Wexford, Waterford and St Mullins Vikings were also slaughtered.the next ten years the Vikings focused their attacks elsewhere in Europe but with less opportunities they returned to Ireland in 914 as much larger force with Vikings of Britain joining their attacks in Viking ships.
