 If the account of the "Annals of the Four Masters" is to be believed, the Dubliners switched sides at this point, deserted the cause of Ua Conchobair, and further suffered an act of divine justice as their town went up in flames.On the other hand, the twelfth-century "Expugnatio Hibernica" specifies that, whilst negotiations were under way between the forces of Ua Conchobair and the coalition of Mac Murchada and Clare, an English force under the command of Miles de Cogan and Raymond le Gros successfully assaulted the town, and caused considerable carnage amongst the inhabitants.Although the "Annals of the Four Masters" specifies that the Dubliners were slaughtered in their fortress, after which the English carried off their cattle and goods, "Expugnatio Hibernica" instead states that the majority of the Dubliners escaped the massacre and retained most of their possessions.
