Tradraige was granted to Robert de Musegros, and the castles of Ogormack (Clare) and Traddery (Bunratty) were built in 1249-1253.

Conor, however, by offer of yearly tribute, was confirmed in the rest of Thomond and the English were nearly completely expelled in 1257 by him and his son Tadhg.

[note 1] In the year 1267, accompanied by the O'Deas, the O'Hehirs, and other tribes of Uí Cormaic and Cineal Fermaic, Conor marched into Burren to enforce the submission of the inhabitants, and was opposed by Conor Carrach O'Loughlin, who had been informed by his scouts that the prince of Thomond had but a comparatively small force.

O'Loughlin, besides his own followers, was assisted by the sons of Domnall Connachtach O'Brien, uncle to Conor, the reigning prince, who had settled in the north-west of Thomond for some time past.

The armies met at the wood of Siudan, in the present parish of Drumcreehy, and a battle ensued, in which Conor lost his life.
