Cromwellian Conquest of Ireland - The Collapse of The Royalist Alliance

The Collapse of The Royalist Alliance

In May 1650, Charles II repudiated his father’s (Charles I's) alliance with the Irish Confederates in preference for an alliance with the Scottish Covenanters (see Treaty of Breda (1650)). This totally undermined Ormonde’s position as head of a Royalist coalition in Ireland. Cromwell published generous surrender terms for Protestant Royalists in Ireland and many of them either capitulated or went over to the Parliamentarian side.

This left in the field only the remaining Irish Catholic armies and a few diehard English Royalists. From this point onwards, many Irish Catholics, including their bishops and clergy, questioned why they should accept Ormonde's leadership when his master, the King, had repudiated his alliance with them. Cromwell left Ireland in May 1650 to fight the Third English Civil War against the new Scottish-Royalist alliance. He passed his command onto Henry Ireton.
