 The "Orkneyinga Saga" fails to mention a campaign in the Irish Sea by Magnus Haraldsson in 1058, (which is the first such event attested in contemporary sources in the British Isles).Woolf (2007) suggests that Torfinn's death provoked Magnus's expedition, and that this was the occasion on which Paul and Erlend Thorfinnsson submitted to Harald.Whatever the timing, on the death of their father the brothers became joint earls although Paul, who was the elder of the two, was "very much the one in charge".
