At the front of Brian's forces were the Dál gCais, led by Brian's son Murchad, Murchad's fifteen-year-old son Toirdelbach, Brian's brother Cudulligh, and Domnall mac Diarmata of Corcu Baiscind. Behind them were the other forces of Munster, commanded by Mothla mac Domnaill mic Fáeláin, King of the Déisi Muman, and Magnus mac Amchada, King of Uí Liatháin. Next came the Connachta, led by Mael Ruanaidh Ua hEidhin and Tadhg Ua Cellaigh. To one side of them were Brian's Viking allies; Fergal ua Ruairc, with the Uí Briúin and the Conmhaícne was placed on the left flank. After the Connachta came Máel Sechnaill and the men of Meath, but (the "Cogad" says) he had made an agreement with the men of Dublin that if he would not attack them, they would not attack him.
