Northern campaign (Irish Republican Army)

The Northern campaign was a series of attacks by the Irish Republican Army (IRA) Northern Command between September 1942 and December 1944 against the security forces in Northern Ireland. The action taken by the Northern Ireland and the Republic of Ireland governments as a result of these attacks shattered the IRA and resulted in the former being free from IRA activity by the end of World War II.

This was the third republican campaign against British rule in Northern Ireland. The first took place during the Irish War of Independence, the second 1939–40, the fourth took place from 1956–1962, the fifth took place from 1969–1997 and sixth from 1997–present.

The campaign
The prime minister of the Irish Free State, Éamon de Valera, complained about the occupation of Irish soil with the arrival of American soldiers in Northern Ireland as part of the war effort against Nazi Germany. This influx of foreign soldiers encouraged the northern command of the IRA, under the auspices of newly appointed commander Hugh McAteer, to reorganise and on 25 March 1942 agree a new campaign against the British military and war effort in Northern Ireland.

Over the first few months of the campaign, a few attacks against the Royal Ulster Constabulary (RUC) in Strabane, Dungannon, and Belfast, resulted in the death of two RUC constables and the wounding of two others. Six IRA members, including Joe Cahill, were arrested during the Belfast incident and sentenced to death for the murder of one of the constables. A petition signed by around two hundred thousand people calling for mercy was gathered by those calling for a reprieve, and several days before the date of the executions, all but one was commuted. The sole IRA member executed was Tom Williams who was hanged at Crumlim Road gaol, Belfast, on 2 September 1942, resulting in the IRA intensifying their attacks.

After the bombing of Randalstown RUC station, and more gunfire attacks against the RUC in parts of West Belfast and across the border area between Northern Ireland and the Irish Free State, around 320 members and suspected members of the IRA, including Hugh McActeer, were arrested across Northern Ireland. One historian, Bowyer-Bell, reports a total of 60 armed attacks by the IRA in the three months up to December 1942, carried out by the remaining fifty to sixty IRA members still at large.

In the first few months of 1943, jail breaks at Crumlin Road and Derry gaols saw 23 IRA members, including McAteer, escape. This however failed to inspire a resumption of activity. Many of the escapees had crossed the border into County Donegal in the Free State and were subsequently recaptured by the Irish Army. The few others that escaped arrest sought refuge from pursuit rather than resuming their attacks.

IRA northern command units in south Londonderry and south Armagh were no longer able to function as required, and contact with units in Counties Cavan and Monaghan started to wane. Bowyer-Bell states of the late-1943 to mid-1943 period that the local commanding officers preferred to avoid arrest, and that anything associated with the IRA such as parades, training, and even meetings ended with fear of internment at Curragh.

By the end of World War II in 1945, the northern command of the IRA, largely as a result of the stern response from the Free State, had been reduced to a few wanted men with Northern Ireland entirely free from IRA activity. The Northern Ireland government couldn't publicly acknowledge the fact their neighbour had essentially defeated the IRA, and the Irish Minister of Justice, Gerald Boland, was heard to boast during the period that "the IRA was dead and he had killed it".

1942

 * Easter Sunday – a heavy gunfight in Belfast left a RUC constable dead, with six IRA members arrested in Cawnpore Street in response. In Dublin, Irish Special Branch attempted to arrest Lasarian Mangan and Brendan Behan. When Mangan seemed to hesitate in using his gun, Behan was heard to shout "Use it, use it. Give it to me and I will shoot the bastards.". Behan was later arrested in Dublin and received fourteen years in prison. The third incident in the time line involved Frank Morris, who began shooting when detained at a RUC border checkpoint in Strabane. He was captured 10 hours later that day, found hiding, immersed up to his neck in river water.
 * 20 April – A new IRA Army Council was elected in the wake of these incidents. At this time it is known that Eoin McNamee in his capacity as Adjutant General met with German agent Günther Schütz shortly before this.
 * 15 August – IRA Army Council meets to confirm the details of the Northern campaign and to draw up a Campaign Proclamation. By this stage the arms and munitions from the IRA's Western and Eastern Command areas had been assembled on the border ready for transport into Northern Ireland.
 * 30 August – IRA GHQ sends word to waiting units to begin the transfer of arms into Northern Ireland. That night three tons of material were transported over the border into Newry, County Down. Two lorries were used to transport the material through RUC checkpoints without incident.  The arms were then stored in a barn attached to McCafferty's farm outside Hannahstown, County Antrim.  The member overseeing the operation on the ground, Daragh O'Connor reported back to GHQ Belfast in person. His message was that the operation had been successful, and distribution of the material could now begin.  Unfortunately for the IRA, a member sent to help Daragh O'Connor to the farm by members of the RUC who proceeded to raid the building.  In the ensuing gun battle O'Connor was shot dead and 3 tons of arms seized.  This however, was not the only shipment of arms into Northern Ireland the IRA had made, and the others were to remain, as yet, undetected.
 * 1 September – The Army Council issued a General Army Order that in the event of the execution of Tommy Williams, all CO's were to take aggressive action.
 * 2 September – Tom Williams' execution at 8am, The first attack afterwards, scheduled was to take place against a British Army barracks in Crossmaglen, County Armagh. Twenty IRA members were led by Patrick Dermody in a commandeered lorry and accompanying car. According to IRA member Harry White, who wrote about the raid in his book of memoirs "Harry", they hoped to capture a British officer and hang him.
 * 3 September – The front of a police barracks in Randalstown, Co. Antrim, was demolished by a mine and a RUC sergeant was injured.

 * 5 September – Two RUC were killed in Clady, County Tyrone. While a failed attack in Belfast saw Gerry Adams Sr. wounded by the RUC.
 * 9 September – Sergeant Denis O'Brien, a serving Irish Special Branch officer and himself a former IRA member, was shot dead by 3 IRA members outside his home in Ballyboden, Rathfarnham, County Dublin. This action was directly against IRA Army Council orders which forbade any operations of a military nature in Éire.  Notice of a five thousand pound reward was issued for information leading to the apprehension of O'Brien's killers along with a list of men wanted in connection with the incident.  Michael Quill was later apprehended by the RUC and turned over to Irish Special Branch in connection with the incident. This led to his internment in January 1943.

Following the initial raid in September, the RUC and Irish Special Branch stepped up their efforts against the IRA. A series of arms finds and arrests were made.
 * 10 September – Belfast IRA lost two members when they were surrounded in a house and captured.

 * 12 October – McAteer and his Director of Intelligence, O'Reilly, were arrested in Northern Ireland by the RUC Criminal Investigation Department (CID). McAteer was later sentenced to 15 years imprisonment for treason, and his position taken over by Charlie Kerins, who was later relieved by Harry White in late October.
 * 19 October – Maurice O'Neill, was captured by Garda Síochána during a raid on a safe house in Holly Road, Donnycarney, County Dublin. A detective died during the raid. Harry White escaped and travelled to Belfast to take over as OC for Northern Command.  During his trial by Military Tribunal in Éire, O'Neill was represented by Seán MacBride.  MacBride failed however, to win O'Neill a reprieve and he was executed by the Irish Government on 12 November 1942.
