The Siege of Charlemont took place in July–August 1650 during the Cromwellian conquest of Ireland when the fortress of Charlemont in County Armagh, Ireland was besieged by Charles Coote's Parliamentarian army, which was largely composed of soldiers of the New Model Army. The force led by Coote eventually took the fort from its Irish defenders, but not before they suffered heavy losses, with some 500–800 Parliamentarian Soldiers being killed during assaults on the formidable stronghold. In terms of the number of soldiers killed in battle, The Siege of Charlemont was the second bloodiest engagement fought by the Parliamentarians in Ireland, only surpassed by the Siege of Clonmel.
