McMahon killings

In July 1921, a truce was agreed between representatives of the Irish Republic and the British Government, ending the Irish War of Independence in most of Ireland. The Anglo-Irish Treaty had been signed in December 1921, which copper-fastened the Partition of Ireland: most of Ireland became the Irish Free State, while Northern Ireland remained part of the United Kingdom. Violence continued in Northern Ireland after the truce. In the first half of 1922, in the words of historian Robert Lynch, the Irish Republican Army (IRA), "would make one final attempt to undermine the ever hardening reality of partition by launching an all out offensive on the recently established province of Northern Ireland".[1]

To counter the IRA, the new unionist Government of Northern Ireland established the Ulster Special Constabulary (USC), a quasi-military reserve police force to the Royal Irish Constabulary, which was first deployed in February 1921. The USC had a mutually hostile relationship with both pro-Treaty nationalists and anti-Treaty republicans in the area which became Northern Ireland. Lynch writes of the USC: "some were polite and courteous, others merely arrogant and destructive whilst a small anonymous minority set out to kill".[2]

The McMahon killings are believed to have been a reprisal for the IRA's killing of two USC policemen in Belfast.[3] On 23 March 1922, USC officers Thomas Cunningham and William Cairnside were patrolling Great Victoria Street in the city centre when they were approached by a group of IRA members and shot dead. Two Catholics, Peter Murphy (61) and Sarah McShane (15), were later shot dead in a suspected reprisal attack several hours later in the Catholic Short Strand area by unidentified gunmen.[4]

The McMahon family had no connection to any paramilitary violence. Owen McMahon was a supporter and personal friend of Joe Devlin, the Irish Parliamentary Party (IPP) Member of Parliament, an Irish nationalist who rejected republican violence.[5] McMahon was a prosperous businessman, who owned several pubs in Belfast (one of which was The Capstan Bar on Ann Street) and had at one time been chairman of the Northern Vintners' Association. His home at Kinnaird Terrace, off the Antrim Road in north-central Belfast, near the New Lodge area, was described as a "sprawling Victorian mansion".[6]

At about 1:00 am on 24 March 1922, two men wearing police uniforms seized a sledgehammer from a Corporation workman, who was guarding a building site at Carlisle Circus. A curfew was in place at the time, due to the daily violence in the city.[7] At nearby Clifton Avenue they met three other men and the party of five proceeded to the home of Owen McMahon. Eight males and three women were in the house that night. The males were Owen, his six sons, and Edward McKinney. McKinney was from Desertegney near Buncrana, County Donegal, across the border in the Irish Free State. He worked for the McMahons as a barman. The women were Owen's wife Eliza, her daughter and her niece.[7] At about 1:20 am, the gang used the sledgehammer to break down the door of the McMahon household.[8]

Owen's wife, Eliza, said that four of the men wore police caps and carried revolvers while another wore civilian clothes.[8] John McMahon, one of Owen's sons, said "Four of the five men were dressed in the uniform of the RIC but, from their appearance, I know they are Specials, not regular RIC". All of the men had hidden their faces. The four men in police uniform rushed up the stairs and herded the males into the dining room.[7] The women were taken into another room. Eliza "got down on her knees and pleaded for mercy, but was struck on the side of the head and fell to the floor". When Owen asked why his family was being singled-out, one of the gunmen said it was because he was "a respected papist".[7] The gunmen said "you boys say your prayers", before opening fire. The shooting continued for five minutes; five of the men were killed outright and two were wounded, one fatally.[9]

Owen McMahon (50), Gerard McMahon (15), Frank McMahon (24), Patrick McMahon (22) and Edward McKinney (25) were killed outright while Bernard McMahon (26) died later. The youngest McMahon son, 12-year-old Michael, survived the attack by hiding behind furniture and pretending to be hit. John McMahon (30) survived despite serious gunshot wounds. Eliza McMahon raised the alarm by opening the drawing room window and shouting "Murder! Murder!" A matron at an adjoining nursing home was alerted and phoned the police and an ambulance.[10]

It has been alleged that a group of policemen operating out of Brown Square barracks in the Shankill Road area were behind the killings, but this has never been proved according to The Daily Telegraph.[8] Historian Tim Pat Coogan believes the police were responsible.[11] An inquiry was carried out by the Department of Defence of the Irish Free State, but not by the Northern Irish authorities. A 1924 Free State report alleged that twelve policemen, whom the report identified by name, had carried out the McMahon murders, as well as several other attacks on Catholics.[12]

The killings caused outrage among Belfast's Catholic population and over 10,000 people attended the funerals of those killed. The funerals of Owen, Gerard, Frank and Patrick were held on Sunday 26 March.[7] The British Army lined the route of the funeral procession – from north Belfast to Milltown Cemetery – anticipating it would be attacked.[7] Edward McKinney was buried on the same day, Sunday, 26 March, in Cockhill Cemetery just outside Buncrana.

At the funeral Mass for the victims at St Patrick's Church, Rev Bernard Laverty told the congregation that even the Black and Tans "had not been guilty of anything approaching this [crime] in its unspeakable barbarity". The McMahons had been "done to death merely because they were Catholics", but he told the mourners to practise "patience and forbearance" and not to seek revenge. Irish Nationalist Party MP Joe Devlin told the British Parliament, "If Catholics have no revolvers to protect themselves they are murdered. If they have revolvers they are flogged and sentenced to death".[13]

David Lloyd George and Winston Churchill, worried that the violence would collapse of the new Northern Ireland administration, organised a meeting in London between Irish republican leader Michael Collins and Sir James Craig, Prime Minister of Northern Ireland, both to try to stop the IRA violence which Collins had been tacitly encouraging and supporting, and to pressure Craig to provide more protection for Catholics. Craig denied the nationalist assertion that the McMahon killings were part of an anti-Catholic pogrom on behalf of state forces, telling the Parliament of Northern Ireland that, "no such thing has ever been the policy of Protestants here ... The Ulster men are up against, not Catholics but ... up against rebels, that they are up against murder, Bolshevism and up against those enemies not only of Ulster but of the [British] Empire".[14]

The killings were part of a series of reprisals on Catholics for IRA attacks in Belfast and elsewhere. The following week saw an incident known as the "Arnon Street killings", in which five Catholics were killed by uniformed police in revenge for the killing of a policeman on the Old Lodge Road. In total, 452 people would be killed in Belfast in the conflict between June 1920 and July 1922 – 267 Catholics and 185 Protestants.[15][16]

No one was ever prosecuted for the killings but DI John William Nixon was forced to step down from the Royal Ulster Constabulary (RUC), albeit on full pension, in 1924 after being heard giving (in breach of police regulations) a political speech to an Orange Order meeting saying that, "not an inch of Ulster should be yielded" to the Free State.[5]
