Perhaps taking advantage of this strife, the King of Munster, Cathal mac Finguine, invaded the midlands in 733. Cathal encamped at Tailtiu, where the Uí Néill high kings traditionally held their main óenach. He was attacked there by Domnall and driven off although he later defeated the minor Uí Néill kindred of Clann Cholmáin Bicc led by Fallomon mac Con Congalt at the Hill of Ward, the site of another major Uí Néill óenach.
