During the Irish Confederate Wars, like most Irish Catholics, he sided with Confederate Ireland. His services to the Catholic Confederation were highly valued by the Supreme Council. The bishop would treat the wounded and support Confederate soldiers throughout the conflict. O'Brien was against a peace treaty that did not guarantee Catholic freedom of worship in Ireland and in 1648 signed the declaration against the Confederate's truce with the Earl of Inchiquin who had committed atrocities such as the Sack of Cashel against Catholic clergy and civilians, and the declaration against the Protestant royalist leader the Duke of Ormonde in 1650 who, due to his failure to resist the Cromwellian conquest of Ireland was not deemed fit to command Catholic troops. He was one of the prelates, who, in August 1650 offered the Protectorate of Ireland to Charles IV, Duke of Lorraine.[6][7]
In 1651 Limerick was besieged and O'Brien urged a resistance that infuriated the Ormondists and Parliamentarians. Following surrender, he was found ministering to the wounded and ill inside a temporary plague hospital. As previously decided by the besieging army, O'Brien was denied quarter and protection. Along with Alderman Thomas Stritch and English Royalist officer Colonel Fennell, Bishop O'Brien was tried by a drumhead court martial and sentenced to death by New Model Army General Henry Ireton.[4][8] On 30 October 1651, Bishop O'Brien was first hanged at Gallows Green and then posthumously beheaded.[9] His severed head was afterwards displayed spiked upon the river gate of the city.[10]
Legacy
Henry Ireton fell ill of the plague that was raging through the city, and died on 26 November. His loss reportedly "struck a great sadness into Cromwell" and he was considered a great loss to the Commonwealth of England. There are various anecdotes about his demise from Irish ecclesiastical and English Royalist sources, by whom Ireton's death has been depicted as divine retribution for the hanging of Bishop O'Brien, who prior to his death had called upon Ireton to answer at God's judgment seat for the New Model Army's massacres. For example, the Hibernica Dominicana claims that on his death bed, Ireton was "privately muttering to himself, 'I never gave the aid of my counsel towards the murder of that bishop; never, never; it was the council of war did it... I wish I had never seen this popish bishop'."[11] In contrast, the memoirs of English Cavalier officer Philip Warwick allege that, in his delirious state, Ireton's last words were, "Blood! blood! I must have more blood!"[12]
In a ruling that was far less popular among his own staff officers, Ireton had similarly sentenced the former Governor of Limerick, Hugh Dubh O'Neill to death by hanging as well; New Model Army General Edmund Ludlow immediately countermanded the order following Ireton's death.[13]
According to historian D.P. Conyngham, "It is impossible to estimate the number of Catholics slain the ten years from 1642 to 1652. Three Bishops and more than 300 priests were put to death for their faith. Thousands of men, women, and children were sold as slaves for the West Indies; Sir W. Petty mentions that 6,000 boys and women were thus sold. A letter written in 1656, quoted by Lingard, puts the number at 60,000; as late as 1666 there were 12,000 Irish slaves scattered among the West Indian islands. Forty thousand Irish fled to the Continent, and 20,000 took shelter in the Hebrides or other Scottish islands. In 1641, the population of Ireland was 1,466,000, of whom 1,240,000 were Catholics. In 1659 the population was reduced to 500,091, so that very nearly 1,000,000 must have perished or been driven into exile in the space of eighteen years. In comparison with the population of both periods, this was even worse than the famine extermination of our own days."[14]
After the successful fight that was eventually spearheaded by Daniel O'Connell for Catholic Emancipation between 1780 and 1829, interest revived as the Catholic Church in Ireland was rebuilding after three hundred years of being strictly illegal and underground. As a result, a series of re-publications of primary sources relating to the period of the persecutions and meticulous comparisons against archival Government documents in London and Dublin from the same period were made by Daniel F. Moran and other historians.
The first Apostolic Process under Canon Law began in Dublin in 1904, after which a positio was submitted to the Holy See.
In the 12 February 1915 Apostolic decree In Hibernia, heroum nutrice, Pope Benedict XV formally authorized the formal introduction of additional Causes for Roman Catholic Sainthood.[16]
During a further Apostolic Process held at Dublin between 1917 and 1930 and against the backdrop of the Irish War of Independence and Civil War, the evidence surrounding 260 alleged cases of Roman Catholic martyrdom were further investigated, after which the findings were again submitted to the Holy See.[17]
On 27 September 1992, O'Brien and sixteen other Irish Catholic Martyrs were beatified by Pope John Paul II. June 20th, the anniversary of the 1584 execution of Elizabethan era martyr Dermot O'Hurley, was assigned as the feast day of all 17.[18] A large backlighted portrait of him is on display in St. Michael's Church, Cappamore, County Limerick, which depicts him during The Siege of Limerick.
