James Butler, 1st Duke of Ormonde
After Charles I was executed in 1649, he stated Ireland's support for Charles II. Ormonde was put in command of the Irish Confederates' armies and also the English Royalist troops who had come to Ireland. Almost all of Ireland was under his control before August 1649. Yet Ormonde was not able to stop the conquest of Ireland by Oliver Cromwell in 1649-50.
