1956 On 12 December, the campaign was launched with simultaneous attacks by around 150 IRA members on targets on the Border in the early hours. A
BBC relay transmitter was bombed in Derry, a courthouse was burned in
Magherafelt by a unit led by an 18-year-old
Seamus Costello, as was a
B-Specials post near
Newry and a half-built Army barracks at
Enniskillen was blown up. A raid on Gough barracks in Armagh was beaten off after a brief exchange of fire. The IRA issued a statement announcing the start of the campaign, "Spearheaded by Ireland's freedom fighters, our people have carried the fight to the enemy...Out of this national liberation struggle a new Ireland will emerge, upright and free. In that new Ireland, we shall build a country fit for all our people to live in. That then is our aim: an independent, united, democratic Irish Republic. For this we shall fight until the invader is driven from our soil and victory is ours". Despite formal condemnation of the IRA by the
Roman Catholic hierarchy, many units were given absolution before going out on operation. On 14 December: an IRA column under
Seán Garland detonated four bombs (one of which blew in the front wall) outside
Lisnaskea RUC station before raking it with gunfire. Further attacks on
Derrylin and
Roslea RUC barracks on the same day were beaten off. On 21 December: In response to the statement the government of Northern Ireland under
Basil Brooke used the
Special Powers Act to intern several hundred republican suspects without trial. Over 100 men were arrested on 12 January 1957. This, in time, severely limited the IRA's capacity to build up units within Northern Ireland. On the evening of December 30, the
Teeling Column under Noel Kavanagh attacked the Derrylin RUC barracks again, killing RUC constable John Scally, the first fatality of the campaign. Others involved in that attack included two prominent IRA men, Charlie Murphy and
Ruairí Ó Brádaigh.
1957 The year 1957 was the most active year of the IRA's campaign, with 341 incidents recorded. The most dramatic attack of the whole campaign took place on 1 January: 14 IRA volunteers, including Séan Garland, Alan O Brien, Paddy O'Regan and
Dáithí Ó Conaill planned an attack on a joint RUC/B Specials barracks in Brookeborough, County Fermanagh, though they attacked the wrong building. During the attack a number of volunteers were injured including Séan Garland.
Fergal O'Hanlon and
Seán South died of their wounds as they were making their escape. The remainder of the group were pursued back over the border by 400 RUC,
B Specials and British soldiers. The funerals of South and O'Hanlon in the Republic produced a strong emotional reaction among the general public there. The two men are still considered martyrs in Irish Republican circles. Up to 50,000 people attended their funerals. Shortly afterwards, the Republic's government, led by John Costello of Fine Gael, feared that the IRA's action would drag it into a diplomatic confrontation with Britain. It used the Offences Against the State Act to arrest most of the IRA's leadership, including its chief of staff, Seán Cronin. The republican
Clann na Poblachta party, led by former IRA Chief of Staff
Seán MacBride, withdrew its support for the government in protest over this policy. In the ensuing Irish general election, 1957, Sinn Féin won four seats and polled 65,640 votes (c. 5% of those cast), while Clann na Poblachta's vote dropped sharply. However, Clann na Poblachta were very weak originally in the constituencies where Sinn Féin fielded candidates. The new government, of Fianna Fáil, led by Éamon de Valera proved even more hostile to the IRA than its predecessor. In July 1957, after the killing of an RUC man, de Valera introduced wholesale internment without trial for IRA suspects. The use of internment on both sides of the Irish border made it impossible for the IRA, most of whose leadership was imprisoned, to maintain the momentum of their campaign. On 11 November: The IRA suffered its worst loss of life in the period when four of its members died preparing a bomb in a farm house at
Edentubber,
County Louth, which exploded prematurely. The civilian owner of the house was also killed. It is believed they were going to attack an empty customs post and electricity pylons in Northern Ireland. They would later be referred to by republicans as the "
Edentubber Martyrs".
1958 – 1960 By 1958, the campaign's initial impetus had largely dissipated. Certain IRA activities produced public hostility and by 1958, there were already many within the IRA in favour of calling the campaign off. The Cork IRA, for instance, had effectively withdrawn. Following their release, some of the interned leaders met Sean Cronin in a farmhouse in
County Laois and were persuaded to continue the campaign "to keep the flame alive". In 1960, the number of incidents fell to just 26. Moreover, many of these actions consisted of minor acts of sabotage, for example the cratering of roads.
Wallace Clark recalled that by this stage the campaign resembled a '
phoney war' at times, as 'casualties remained providentially light' and normal life carried on 'almost uninterrupted'. In the summer of 1958, two IRA men were killed in separate gun battles with the RUC on the border in County Fermanagh, Aloysius Hand in July and James Crossan in August. On July 15-17, 1958 explosions were carried out along the length of the border from counties
Down to
Londonderry resulting in the destruction of the largest border customs post at
Killean, County Armagh on the main Dundalk-Belfast road. The period after the summer of 1958 saw a steep drop in the intensity of the IRA campaign. That the IRA's campaign had run its course by 1960 is testified by the fact that the Republic of Ireland's government closed the
Curragh Camp, which housed internees in the South, on 15 March 1959 (judging them to be no further threat). The Northern Irish government followed suit on 25 April 1961.
1961 In November 1961, an RUC officer, William Hunter, was killed in a gun battle with the IRA in south
County Armagh. This was the final fatality of the conflict. Minister for Justice,
Charles Haughey reactivated the
Special Criminal Court, which handed down long prison sentences to convicted IRA men. ==End of the campaign==
