during the summer of 1132, conchobhair o brian of thomond (modern north munster) invaded hy-many where he ""plundered ... maenmhagh ... [and] carried off many cows."" this raid was purely of a plundering nature, yet apparently within a very short period of time, he followed it up with a full-scale assault on o conchobair's new naval base at dún béal gallimhe. the annals of the four masters noted that ""the castle of bun-gaillmhe was burned and demolished [by] a fleet of the men of munster."" the munstermen then followed this up with a devastating raid on both clan fergal and magh seola, for the same annals note that ""a great slaughter was made of the connachtmen by the men of munster, wherein conchobhar ua flaithbheartaigh, lord of west connacht"" was slain.
