Part II. History of Thomond
Chapter 12. History of Thomond before it was formed into an English county: From the earliest times, to the death of De Clare, and expulsion of the English in 1318.

Donogh O’Brien opposes him—Names of the adherents of Donogh; They meet and fight near Corcomroe Abbey; Donogh slain and his forces utterly defeated

To oppose these, Donogh, grandson of Brian Roe, summoned to his assistance his brother Brian Bane, his cousin-german, Murtagh garv, son of his uncle Donogh; Brian Bearra, Tiege Luimneigh, son of Brian Roe; the clan Mahon, the clan Teige (O’Brien), the inhabitants of Tuachadh-na-Faiseach (i.e., Ui Bloid); Loghlen, the O’Gradys, the clan Giolla Mochaine, the clan Flaherty O’Dea, the MacDonagans, the O’Shanahans, the O’Aherns, the O’Hogans, and the O’Kennedys. These being assembled, slept the first night at Cill-Litire-Maoel Odhrain. ^[47] Thence they proceeded to Loghraska, and there came in sight of a hag, whose hideousness is described by the Irish historian in terms of laughable exaggeration, and whom they found employed in washing the blood off a pile of limbs and carcasses of dead men. These, she said, were symbolical of the heads and limbs of Donogh himself and his followers, who were doomed to perish in the approaching combat. Nor was that combat long a-coming: Dermot leading his forces that same day from the abbey of Corcomroe, came in sight of his enemies, and gave them battle at Druim Lurgain. Before the fight began, he addressed his troops, and his exhortation was followed by another in verse, from his chief poet, it being the custom amongst the Irish that the bard should accompany and encourage his kinsfolk in battle. In the conflict that ensued Donogh was slain by the hand of O’Connor of Corcomroe, his party utterly defeated, and nearly the entire following of Brian Roe extirpated. The victors purchased their success dearly, no less than twenty-one principal men of the MacNamaras, four leaders of the O’Moloney’s, and two of the O’Hallorans having fallen. After the battle, the chiefs of either party were buried by Dermot, with all honours, in separate graves, in the neighbouring abbey. The victory thus gained, finally decided the right to the chieftaincy of Thomond, and placed it, indisputably, in the race of Turlogh. It moreover led to the annihilation of de Clare, and to the expulsion of the English from the country, for the final struggle took place not long afterwards.
