(1585–1655), Confederate Catholic general of Leinster. An expert at siege warfare, he took Birr (1643), Ballinakill (1643), Duncannon (1645), Roscommon (1646), and Carlow (1648), and made honourable defences of Waterford (1650) and Galway (1652), but lost disastrously in the field at New Ross (1642) and Dungan's Hill (1648). Quarrels with Castlehaven and Owen Roe O'Neill aborted important campaigns. Excommunicated by Rinuccini, he found the royalists, who made him Viscount Tara, more amenable allies.
