A leader during the Confederate Ireland wars, Feiritéar was wounded during an attack by Oliver Cromwell's Roundheads on the Feiritéar stronghold of Tralee Castle in 1641. The Clan forces held the castle until the fall of Ross Castle in Killarney to the Cromwellians in June 1653. Granted safe passage by Cromwellian commander Brigadier Nelson, Feiritéar travelled to arrange surrender terms. Instead, he was seized at Castlemaine and hanged alongside others, including his brother-in-law, the Dominican priest Tadhg Ó Muircheartaigh, on Cnocán na gCaorach in Killarney on 15 October 1653.
