Irish campaign controversy
The extent of Cromwell's brutality in Ireland has been strongly debated. Some historians argue that Cromwell never accepted responsibility for the killing of civilians in Ireland, claiming that he had acted harshly but only against those "in arms". Other historians cite Cromwell's contemporary reports to London, including that of 27 September 1649, in which he lists the slaying of 3,000 military personnel, followed by the phrase "and many inhabitants". In September 1649, he justified his sacking of Drogheda as revenge for the massacres of Protestant settlers in Ulster in 1641, calling the massacre "the righteous judgement of God on these barbarous wretches, who have imbrued their hands with so much innocent blood". But the rebels had not held Drogheda in 1641; many of its garrison were in fact English royalists. On the other hand, the worst atrocities committed in Ireland, such as mass evictions, killings and deportation of over 50,000 men, women and children as prisoners of war and indentured servants to Bermuda and Barbados, were carried out under the command of other generals after Cromwell had left for England. Some point to his actions on entering Ireland. Cromwell demanded that no supplies be seized from civilian inhabitants and that everything be fairly purchased; "I do hereby warn ... all Officers, Soldiers and others under my command not to do any wrong or violence toward Country People or any persons whatsoever, unless they be actually in arms or office with the enemy ... as they shall answer to the contrary at their utmost peril."
The massacres at Drogheda and Wexford were in some ways typical of the day, especially in the context of the recently ended Thirty Years' War, although there are few comparable incidents during the Civil Wars in England or Scotland, which were fought mainly between Protestant adversaries, albeit of differing denominations. One possible comparison is Cromwell's Siege of Basing House in 1645—the seat of the prominent Catholic the Marquess of Winchester—which resulted in about 100 of the garrison of 400 being killed after being refused quarter. Contemporaries also reported civilian casualties, six Catholic priests and a woman. The scale of the deaths at Basing House was much smaller. Cromwell himself said of the slaughter at Drogheda in his first letter back to the Council of State: "I believe we put to the sword the whole number of the defendants. I do not think thirty of the whole number escaped with their lives." Cromwell's orders—"in the heat of the action, I forbade them to spare any that were in arms in the town"—followed a request for surrender at the start of the siege, which was refused. The military protocol of the day was that a town or garrison that rejected the chance to surrender was not entitled to quarter. The refusal of the garrison at Drogheda to do this, even after the walls had been breached, was to Cromwell justification for the massacre. Where Cromwell negotiated the surrender of fortified towns, as at Carlow, New Ross, and Clonmel, some historians argue that he respected the terms of surrender and protected the townspeople's lives and property. At Wexford, he again began negotiations for surrender. The captain of Wexford Castle surrendered during the negotiations and, in the confusion, some of Cromwell's troops began indiscriminate killing and looting.
Although Cromwell's time spent on campaign in Ireland was limited and he did not take on executive powers until 1653, he is often the central focus of wider debates about whether, as historians such as Mark Levene and John Morrill suggest, the Commonwealth conducted a deliberate programme of ethnic cleansing in Ireland. Faced with the prospect of an Irish alliance with Charles II, Cromwell carried out a series of massacres to subdue the Irish. Then, once Cromwell had returned to England, the English Commissary, General Henry Ireton, Cromwell's son-in-law and key adviser, adopted a deliberate policy of crop burning and starvation. Total excess deaths for the entire period of the Wars of the Three Kingdoms in Ireland was estimated by William Petty, the 17th-century economist, to be 600,000 out of a total Irish population of 1,400,000 in 1641.
The sieges of Drogheda and Wexford have been prominently mentioned in histories and literature up to the present day. James Joyce, for example, mentioned Drogheda in his novel Ulysses: "What about sanctimonious Cromwell and his ironsides that put the women and children of Drogheda to the sword with the Bible text 'God is love' pasted round the mouth of his cannon?" Similarly, Winston Churchill (writing in 1957) described Cromwell's impact on Anglo-Irish relations:
[U]pon all of these Cromwell's record was a lasting bane. By an uncompleted process of terror, by an iniquitous land settlement, by the virtual proscription of the Catholic religion, by the bloody deeds already described, he cut new gulfs between the nations and the creeds. 'Hell or Connaught' were the terms he thrust upon the native inhabitants, and they for their part, across three hundred years, have used as their keenest expression of hatred 'The Curse of Cromwell on you.' ... Upon all of us there still lies 'the curse of Cromwell'.
A key surviving statement of Cromwell's views on the conquest of Ireland is his Declaration of the lord lieutenant of Ireland for the undeceiving of deluded and seduced people of January 1650. In this he was scathing about Catholicism, saying, "I shall not, where I have the power... suffer the exercise of the Mass." But he also wrote: "as for the people, what thoughts they have in the matter of religion in their own breasts I cannot reach; but I shall think it my duty, if they walk honestly and peaceably, not to cause them in the least to suffer for the same." Private soldiers who surrendered their arms "and shall live peaceably and honestly at their several homes, they shall be permitted so to do".
In 1965 the Irish minister for lands stated that his policies were necessary to "undo the work of Cromwell". In 1997, Irish Taoiseach Bertie Ahern later said, he voiced "forthright" views to British Foreign Secretary Robin Cook when his delegation saw a portrait of Cromwell in a room in the Foreign Office.
Multiple Irish folk songs mention Cromwell in a negative light. A few examples of songs mentioning Cromwell include The Men Behind the Wire which has lyrics about Cromwell harming England's global reputation and A Final Toast for Oliver Cromwell by Ye Banished Privateers which is a modern take on Cromwell's legacy. The song Young Ned Of The Hill by The Pogues which includes a direct curse onto Cromwell has the lyrics:
A curse upon you Oliver Cromwell. You who raped our Motherland. I hope you're rotting down in hell, For the horrors that you sent. To our misfortunate forefathers, Whom you robbed of their birthright. To hell or Connaught, May you burn in hell tonight.
