The Eoganacht King, Mael Muad, organised an anti-Dalcassian alliance that included at least one other Irish ruler in Munster, and Ivar, the ruler of Limerick.
At the Battle of Sulchoid a Dalcassian army led by Mathgamain and Boru decisively defeated the Hiberno-Norse army of Limerick and, following up their victory, looted and burned the city.
