The Maze Prison escape, known to Irish republicans as the Great Escape, takes place on September 25, 1983 in County Antrim, Northern Ireland. HM Prison Maze, also known as Long Kesh, is a maximum security prison considered to be one of the most escape-proof prisons in Europe, and holds prisoners suspected of taking part in armed paramilitary campaigns during the Troubles. In the biggest prison escape in UK history, 38 Provisional Irish Republican Army (IRA) prisoners escaped from H-Block 7 (H7) of the prison. One prison officer dies of a heart attack during the escape and twenty others are injured, including two who are shot with guns that had been smuggled into the prison. The escape is a propaganda coup for the IRA, and a British government minister faces calls to resign. The official inquiry into the escape places most of the blame onto prison staff, who in turn blame the escape on political interference in the running of the prison.

IRA volunteers regard themselves as prisoners of war with a duty to escape. During the Troubles, Irish republican prisoners escape from custody en masse on several occasions between 1971 and 1981.

Prisoners had been planning the 1983 escape for several months. Bobby Storey and Gerry Kelly start working as orderlies in H7, which allows them to identify weaknesses in the security systems. Six handguns are also smuggled into the prison. Shortly after 2:30 PM on September 25, prisoners seize control of H7 by simultaneously taking the prison officers hostage at gunpoint in order to prevent them from triggering an alarm. One officer is stabbed with a craft knife, and another is knocked down by a blow to the back of the head. One officer who attempts to prevent the escape is shot in the head by Gerry Kelly, but survives. By 2:50 PM the prisoners are in control of H7 without an alarm being raised. A dozen prisoners also take uniforms from the officers, and the officers are forced to hand over their car keys and details of where their cars are, for possible later use during the escape. A rearguard is left behind to watch over hostages and keep the alarm from being raised until they believe the escapees are clear of the prison, at which time they return to their cells. At 3:25 PM, a lorry delivering food supplies arrives at the entrance to H7, whereupon Brendan McFarlane and other prisoners take the occupants hostage at gunpoint and move them inside H7. The lorry driver is told the lorry is being used in the escape, and he is instructed what route to take and how to react if challenged.

At 3:50 PM the prisoners leave H7, and the driver and a prison orderly are taken back to the lorry. Thirty-seven prisoners climb into the back of the lorry, while Gerry Kelly lay on the floor of the cab with a gun pointed at the driver, who is also told the cab has been booby trapped with a hand grenade. At nearly 4:00 PM the lorry drives toward the main gate of the prison, where the prisoners intend to take over the gatehouse. Ten prisoners dressed in guards’ uniforms and armed with guns and chisels dismount from the lorry and enter the gatehouse, where they take the officers hostage.

At 4:05 PM the officers begin to resist, and an officer presses an alarm button. When other staff respond via an intercom, a senior officer says while being held at gunpoint that the alarm had been triggered accidentally. By this time the prisoners are struggling to maintain control in the gatehouse due to the number of hostages. Officers arriving for work are entering the gatehouse from outside the prison, and each is ordered at gunpoint to join the other hostages. Officer James Ferris runs from the gatehouse toward the pedestrian gate attempting to raise the alarm, pursued by Dermot Finucane. Ferris had already been stabbed three times in the chest, and before he can raise the alarm he collapses.

Finucane continues to the pedestrian gate where he stabs the officer controlling the gate, and two officers who had just entered the prison. This incident is seen by a soldier on duty in a watchtower, who reports to the British Army operations room that he has seen prison officers fighting. The operations room telephones the prison’s Emergency Control Room (ECR), which replies that everything is all right and that an alarm had been accidentally triggered earlier.

At 4:12 PM the alarm is raised when an officer in the gatehouse pushes the prisoner holding him hostage out of the room and telephones the ECR. However, this is not done soon enough to prevent the escape. After several attempts the prisoners open the main gate, and are waiting for the prisoners still in the gatehouse to rejoin them in the lorry. At this time two prison officers block the exit with their cars, forcing the prisoners to abandon the lorry and make their way to the outer fence which is 25 yards away.

Four prisoners attack one of the officers and hijack his car, which they drive toward the external gate. They crash into another car near the gate and abandon the car. Two escape through the gate, one is captured exiting the car, and another is captured after being chased by a soldier. At the main gate, a prison officer is shot in the leg while chasing the only two prisoners who have not yet reached the outer fence. The prisoner who fires the shot is captured after being shot and wounded by a soldier in a watch tower, and the other prisoner is captured after falling. The other prisoners escape over the fence, and by 4:18 PM the main gate is closed and the prison secured, after 35 prisoners had breached the prison perimeter. The escape is the biggest in British history, and the biggest in Europe since World War II.

Outside the prison the IRA has planned a logistical support operation involving 100 armed members, but due to a miscalculation of five minutes, the prisoners find no transport waiting for them and are forced to flee across fields or hijack vehicles. The British Army and Royal Ulster Constabulary immediately activate a contingency plan and by 4:25 PM a cordon of vehicle checkpoints are in place around the prison, and others are later in place in strategic positions across Northern Ireland, resulting in the recapture of one prisoner at 11:00 PM. Twenty prison officers are injured during the escape, thirteen are kicked and beaten, four stabbed, and two shot. One prison officer, James Ferris, who had been stabbed, dies after suffering a heart attack during the escape.

The escape is a propaganda coup and morale boost for the IRA, with Irish republicans dubbing it the “Great Escape.” Leading unionist politician Ian Paisley calls on Nicholas Scott, the Parliamentary Under-Secretary of State for Northern Ireland, to resign. The British Prime Minister Margaret Thatcher makes a statement in Ottawa during a visit to Canada, saying “It is the gravest [breakout] in our present history, and there must be a very deep inquiry.” The day after the escape, Secretary of State for Northern Ireland James Prior announces an inquiry to be headed by Her Majesty’s Chief Inspector of Prisons, James Hennessy. The Hennessy Report is published on January 26, 1984 placing most of the blame for the escape on prison staff, and making a series of recommendations to improve security at the prison. The report also places blame with the designers of the prison, the Northern Ireland Office and successive prison governors who had failed to improve security. Prior announces that the prison’s governor has resigned, and that there will be no ministerial resignations as a result of the report’s findings. Four days after the Hennessy Report is published, the Minister for Prisons Nicholas Scott dismisses allegations from the Prison Governors Association and the Prison Officers Association that the escape is due to political interference in the running of the prison.

Fifteen escapees are captured on the day, including four who are discovered hiding underwater in a river near the prison using reeds to breathe. Four more escapees are captured over the next two days, including Hugh Corey and Patrick McIntyre who are captured following a two-hour siege at an isolated farmhouse. Out of the remaining 19 escapees, 18 end up in the republican stronghold of South Armagh where two members of the IRA’s South Armagh Brigade are in charge of transporting them to safehouses, and given the option of either returning to active service in the IRA’s armed campaign or a job and new identity in the United States.

On October 25, 1984, nineteen prisoners appear in court on charges relating to the death of prison officer James Ferris, sixteen charged with his murder. A pathologist determines that the stab wounds Ferris suffered would not have killed a healthy man. The judge acquits all sixteen as he cannot correlate the stabbing to the heart attack.
