If the attack was indeed a case of retaliation it may not have been due to Rǫgnvaldr's own involvement with enemies of the English Crown. The fleeing Briouzes were also accompanied by Hugh himself, but unlike them he managed to elude capture, and was temporarily harboured in Scotland by Ailín II, Earl of Lennox. The Lacys' previous connections with Dublin and Ulster suggest that Hugh may have had supporters on Mann. In fact, his stay-over in Rǫgnvaldr's absence may have been enabled due to the fraternal discord between Rǫgnvaldr and Óláfr. A correlation between the Lacys and the struggle between Óláfr and Rǫgnvaldr may be exemplified by a 1217 royal order directed at Hugh's half-brother, William Gorm de Lacy, commanding him to restore Carlingford Castle, and repay the damages which he had caused in capturing it. The fact that Rǫgnvaldr received restoration of his nearby knight's fee in 1219 could indicate that these lands had also been overrun and seized by the Lacys.
