The Munster-Meath army defeated the Leinster-Dublin army. Later historians have also seen the battle as decisive. The sources point to high mortality on both sides. According to the Annals of Innisfallen, which represents a Munster perspective, "formna Gall herend" ('the best part of the foreigners of Ireland') fell therein. The more partisan Cogad Gáedel re Gallaib indulges in hyperbole, claiming that "since the Battle of Mag Rath to that time there had not taken place a greater slaughter". The fallen included Harald son of Amlaib (a brother of Sitriuc Silkbeard) and "other nobles of the foreigners", amongst whom was one Cuilén son of Eitigén, who apparently belonged to the Gailenga; he may have been a brother of Ruadacán son of Eitegén, king of Airther Gaileng, who died in 953.
