Desmond Capture

Abstract
In 1370, Brian Sreamhach Ó Briain defeated and captured Gerald FitzGerald, earl of Desmond, near Monasternenagh, then pressured Limerick, which was burned and briefly placed under Mac Conmara control. King’s lieutenant William of Windsor secured Desmond’s release, recovered the city and agreed reparations of cattle and timber. His government, hampered by inadequate funds, also faced fighting in Wicklow. Elsewhere, Niall Mór Ó Néill consolidated Tyrone through hostages, land grants, marriage and victory over Brian Mór Mac Mathghamhna. Captures, succession disputes and raids in Breifne and Leinster further demonstrated that Irish power rested on local alliances, coercion, resources and negotiated settlements.
