Long the underdogs, they emerged in a bright sunset of Gaelic culture, as protectors of a dying culture, and their mountain fastness of Glenmalure became a refuge of the persecuted, a last bastion of Gealdom.
Feach Mac Hugh O’Byrne was a player in the international politics, a national hero, and the greatest hero, and the greatest military genius of the Gaelic military resistance. (Rothwell-Byrne:2012)
