following his expulsion, ragnall appears to have gone into exile at alan's court in galloway. in 1228, whilst amlaíb dub and his chieftains were absent in hebrides, the chronicle records the invasion of mann by ragnall, alan, and thomas. the attack appears to have resulted in the complete devastation of the southern half of the island, since the chronicle declares that it was almost reduced to a desert. the chronicle's report that alan installed bailiffs on mann, with instructions to collect tribute from the island and send it back to galloway, may reveal the price that ragnall had to pay for alan's support in the affair. suffering serious setbacks at the hands of his enemies, amlaíb dub reached out for english assistance against ragnall, as evidenced from correspondence dating to the same year, between henry and amlaíb dub, in which the latter alluded to aggression dealt from alan. gallovidian successes were short-lived, however, as once alan left mann for home, amlaíb dub and his forces arrived on the scene, and routed the remaining gallovidians.
