the only record of this argyllian campaign is preserved by "gesta annalia i", which notes that alexander's forces included gallovidians. both this source and the "orygynale cronykil of scotland" by andrew wyntoun, reveal that alexander's troops mounted a second and successful assault the following year, resulting in the region's submission. the target of alexander's animosity may have been ruaidrí mac ragnaill, lord of kintyre, who appears to have held kintyre and the outer islands of the clyde. it is uncertain if the latter had been aiding the meic uilleim, although his recorded involvement with thomas in 1212 against the cenél neógain suggests otherwise. if, on the other hand, ruaidrí had involved himself with diarmait, an opponent of henry's ally cathal crobderg ua conchobair, king of connacht, ruaidrí would have placed himself at odds with both english and scottish interests. whatever the case, following the second royal campaign into argyll, alexander soon consolidated his authority in the firth of clyde through the apparent expulsion of ruaidrí, the construction of a royal castle at tarbert, the erection of a royal burgh at dumbarton in 1222, and the eventual endowment of cowal to the family of the royal steward.
