Oliver Cromwell failed to siege Waterford!
Cromwell stated after he had failed to siege Waterford that: 'it being so terrible a day I ever marched in my life'.
Another siege by Henry Ireton left its mark!
A cannonball launched by Henry Ireton’s ships in the second siege of Waterford is still embedded in Reginald’s Tower!
In 1641, the Irish Rebellion started. There was conflict inside Waterford between Old English Catholic families and the newly settled Protestants about whether or not to join the rebellion. Most Protestants were deported after a struggle with their belongings and homes being seized.
Waterford was besieged by Oliver Cromwell, he was forced to concede and left Ireland soon after. Waterford was the only city he personally failed to take during his campaign in Ireland.
The city was besieged again, this time by Henry Ireton, Cromwell's son-in-law. The city soon surrendered to avoid its citizens being slaughtered.
