 If these kings were Amlaíb and Ímar, this must have been their last raid on Irish soil, for within a year Ímar was dead.Ímar's death is recorded in the "Annals of Ulster" and the "Chronicon Scotorum" under the year 873.In the "Fragmentary Annals of Ireland", under the same year, it is reported that "the king of Lochlainn" died of a "sudden horrible disease".
