[Sidenote: Brian and the Danes, Gormflaith.] Having in vain sought a refuge with the northern Irish, Sitric was forced to submit to Brian, who reinstated him at Dublin as a tributary king. Sitric's mother, Gormflaith, or Kormlada, was sister to Maelmordha, King of Leinster, and her husband, King Olaf, having been dead many years, she was free to marry Brian, which she did soon after, while Brian's daughter married Sitric. Wielding thus the whole force of southern Ireland, Brian called upon Malachi to acknowledge his supremacy. The King of Ireland sought aid in vain from his kinsmen, the northern Hy Neill, whose king Aedh, or Hugh, sarcastically remarked that when his clan had held the chief kingship they had known how to defend their own. No help coming from Connaught either, Malachi was forced to submit to Brian's power, and though no formal cession took place the King of Ireland quietly subsided into King of Meath. [Sidenote: Brian, King of all Ireland, 1002.] Brian was henceforth reckoned as monarch of Ireland. He invaded Connaught with a flotilla on the Shannon and an army marching on land, and the chiefs of the western province were glad to give hostages. The Ulster potentates falling out among themselves, the north also was easily subdued, and Brian became the actual lord paramount of Ireland. After this he made a tour round the island, starting from the Shannon and marching through Roscommon and over the Curlew mountains into Sligo. Hugging the coast by Ballyshannon to Donegal, he crossed Barnesmore Gap into Tyrone, and then passing the Foyle, near Lifford, he went through Londonderry, Antrim, Down, and Louth, to the neighbourhood of Kells. In a previous expedition he had visited Armagh and laid twenty ounces of gold on the altar. A fleet, manned by the Danes of Dublin, Limerick, and Waterford, seems to have circumnavigated Ireland while he was making the circuit by land.
