The death of Alan's ally did not deter Gallovidian interests in the Isles. In fact, it is apparent that Alan and members of the Clann Dubhghaill branch of Clann Somhairle upheld pressure upon Óláfr. Reports of open warfare in the Isles reached Hákon's royal court in the summer of 1229. The thirteenth-century "Hákonar saga Hákonarsonar" specifically singles out Alan as one of the principal perpetrators of unrest, describing him as "the greatest warrior", possessing a large force of men and ships with which he plundered throughout the Hebrides. Several members of Clann Somhairle are also associated with this unrest: Dubhghall mac Dubhghaill, Donnchadh mac Dubhghaill, and a certain Somhairle. Whilst these members of Clann Somhairle are depicted as being disloyal to Hákon, the saga contrasts them with Óláfr, who is said to have been a steadfast supporter of Hákon, and to have manfully held his kingdom against Alan.
