however the following year toirdhealbhach was decisively defeated by o conchobair and his vassals at feara ceall in the sliabh bloom; o brian had been en route to meath to fight o ruairc but had been intercepted by o conchobair. o brian was forced to return home, ""without prey, without hostage, without peace, without truce."" this brought o brian and o conchobhair into open war; o brian struck within the same year with "an army into connacht; and they carried off ua ceallaigh, i.e. tadhg, son of conchobhar, lord of ui-maine, and slew ruaidhri ua flaithbheartaigh". the death of ua flaithbheartaigh indicates that an attempt may have been made on gallimhe, but o brian would have to wait a full four years before he reached this objective.
