Cause

During the Anglo-Norman invasion of Ireland, Earl Richard 'Strongbow' de Clare led an expedition into Munster with the aim of plundering the province. High King Ruaidrí Ua Conchobair marched to defend Munster, prompting the Anglo-Normans to call on the Ostmen of Dublin for additional support before converging near Thurles.

Event

An alliance of Irish forces including the Dalcassians under Donnell O'Brien, contingents from West Connaught and Sil-Murray, and troops loyal to the High King met the Anglo-Norman army near Thurles. A pitched battle was fought in which the Irish decisively defeated the English, reportedly killing 1,700 of their number.

Consequence

Strongbow and the surviving Anglo-Norman forces retreated in defeat to Waterford, temporarily checking English expansion into Munster. Donnell O'Brien returned home in triumph, and the battle stands as one of the more notable Irish military successes during the broader Anglo-Norman conquest of Ireland.
