The Battle of Aura (Battle of Slieve-na-Aura), was fought in the middle of the sixteenth century between the MacDonnells, led by Sorley Boy MacDonnell, against the McQuillans and O'Neills, in which the MacQuillans and O'Neills were defeated. Translated, Slieve-an-Aura means Hill of Battle - the modern spelling is Slieveanorra.
