Background and detail
Strategic Context. During the summer of 1647, Murrough O'Brien ravaged Confederate territory in Munster. The Irish Munster army was weakened by political infighting between officers supporting and rejecting a deal with English Royalists, rendering them incapable of effectively stopping O'Brien's experienced forces.
The Engagement. The battle at Knocknanauss was characterized as an uncoordinated rout of the Irish forces. Alasdair MacColla commanded the right wing under the overall command of Viscount Taaffe. The engagement resulted in a crushing defeat for the Confederates, with approximately 3,000 Confederates and up to 1,000 Parliamentarians killed.
Consequences. The defeat at Knocknanauss, combined with the earlier loss at Dungans Hill, led to the collapse of the Confederate Catholic cause. This forced the Confederates to negotiate a deal with the English Royalists. Alasdair MacColla died in the battle.
