John died in October 1216, and was succeeded by his young son, Henry III. On one hand, the English summons of Rǫgnvaldr, dated 16 January 1218, in which he was ordered to amend certain "excesses" committed upon Henry III's men in Ireland and England, could be evidence that Islesmen took advantage of the somewhat fractured English realm by plundering the coasts of England and Ireland. If this was indeed the case, there is no further evidence of any such depredations. On the other hand, the "excesses" could specifically relate to an instance reported by the "Annals of Loch Cé", in which Irish herring-fishermen are stated to have committed violence on Mann, and were slain as a consequence of their actions. Later in May, the English Crown commanded that Rǫgnvaldr was to be given safe passage to England in order account for the misconduct of his men.
