sentences:  There is reason to suspect that this account instead masks an historical incident in which the king fled from Kintyre to a Clann Domhnaill castle on Islay—perhaps Dunyvaig Castle—the next northern-most island.If the account of Rathlin given by the "Bruce" actually refers to Islay, it is still uncertain if Aonghus Óg played any part in the king's salvation.In any case, contemporary sources reveal that Dunaverty Castle succumbed to an English-backed siege in September.
