On 21 November 1974, bombs exploded in two pubs in Birmingham, England, killing 21 people and injuring 182 others.
The Provisional IRA never officially admitted responsibility for the bombings, although a former senior officer of the organisation confessed to their involvement in 2014. In 2017, one of the alleged perpetrators, Michael Hayes, also claimed that the intention of the bombings had not been to harm civilians, and that their deaths had been caused by an unintentional delay in delivering an advance telephone warning to security services.
Six Irishmen were arrested within hours of the blasts and, in 1975, sentenced to life imprisonment for the bombings. The men—who became known as the Birmingham Six—maintained their innocence and insisted police had coerced them into signing false confessions through severe physical and psychological abuse. After 16 years in prison, and a lengthy campaign, their convictions were declared unsafe and unsatisfactory, and quashed by the Court of Appeal in 1991. The episode is seen as one of the worst miscarriages of justice in British legal history.
The Birmingham pub bombings were one of the deadliest acts of the Troubles and the deadliest act of terrorism to occur in England between the Second World War and the 2005 London bombings.
In 1973, the Provisional IRA extended its campaign to England, attacking military and symbolically important targets to both increase pressure on the British government, via popular British opinion, to withdraw from Northern Ireland, and to maintain morale amongst their supporters. By 1974, mainland Britain saw an average of one attack—successful or otherwise—every three days. These attacks included five explosions which had occurred in Birmingham on 14 July, one of which had occurred at the Rotunda. Prior to any attack upon civilian targets, a code of conduct was followed in which the attacker or attackers would send an anonymous telephone warning to police, with the caller reciting a confidential code word known only to the Provisional IRA and to police, to indicate the authenticity of the threat.
On 14 November, James McDade, a 28-year-old UK-based member of the Provisional IRA, was killed in a premature explosion as he attempted to plant a bomb at a telephone exchange and postal sorting office in Coventry. Another man, Raymond McLaughlin, was arrested near the scene; he was charged with unlawfully killing McDade and causing an explosion. The republican movement in England had planned to bury McDade in Birmingham, with a paramilitary guard of honour. These plans were altered after the British Home Secretary vowed that such a funeral, and any associated sympathy marches, would be prevented. Councils in the West Midlands chose to ban any processions linked to the death of McDade under the Public Order Act 1936.
McDade's body was driven to Birmingham Airport and flown to Ireland on the afternoon of 21 November 1974. Initially, his body had been scheduled to be flown to Belfast Airport; however, upon learning that staff at the airport had refused to handle the coffin, McDade's body was instead flown to Dublin. All police leave was cancelled on this date, with an extra 1,300 officers drafted into Birmingham to quell any unrest as the hearse carrying McDade's coffin was driven to the airport. McDade's body was buried in Milltown Cemetery in Belfast on 23 November. According to a senior Provisional IRA figure, tensions within the Birmingham IRA unit were "running high" over the disrupted funeral arrangements for James McDade.
On the early evening of 21 November, at least three bombs connected to timing devices were planted inside two public houses and outside a bank located in and around central Birmingham. It is unknown precisely when these bombs were planted; if official IRA protocol of preceding attacks upon non-military installations with a 30-minute advance warning to security services was followed, and subsequent eyewitness accounts are accurate, the bombs would have been planted at these locations after 19:30 and before 19:47.
According to testimony delivered at the 1975 trial of the Birmingham Six, the bomb planted inside the Mulberry Bush was concealed inside either a duffel bag or briefcase, whereas the bomb planted inside the Tavern in the Town was concealed inside a briefcase or duffel bag (possibly concealed within a large, sealed plastic bag) and Christmas cracker boxes. The remnants of two alarm clocks recovered from the site of each explosion leaves the possibility that two bombs had been planted at each public house; the explosion crater at each location indicates that if two bombs had been planted at each public house, they would each have been placed in the same location and likely the same container.
Reportedly, those who planted these bombs then walked to a preselected phone box to telephone the advance warning to security services; however, the phone box had been vandalised, forcing the caller to find an alternative phone box and thus shortening the amount of time police had to clear the locations.
At 20:11, an unknown man with a distinct Irish accent telephoned the Birmingham Post newspaper stating "There is a bomb planted in the Rotunda and there is a bomb in New Street at the tax office. This is Double X", before terminating the call. ("Double X" was an IRA code word given to authenticate any warning call.) A similar warning was also sent to the Birmingham Evening Mail newspaper, with the anonymous caller(s) again giving the code word, but again failing to name the public houses in which the bombs had been planted.
The Rotunda is a 25-storey office block, built in the 1960s, that housed the Mulberry Bush pub on its lower two floors. Within minutes of the warning, police arrived and began checking the upper floors of the Rotunda, but they did not have sufficient time to clear the crowded pub at street level. At 20:17, six minutes after the first telephone warning had been delivered to the Birmingham Post, the bomb—which had been concealed inside either a duffel bag or briefcase located close to the rear entrance to the premises—exploded, devastating the pub. The explosion blew a 40-inch (100 cm) crater in the concrete floor, collapsing part of the roof and trapping many casualties beneath girders and concrete blocks. Many buildings near the Rotunda were also damaged, and pedestrians in the street were struck by flying glass from shattered windows. Several of the victims died at the scene, including two youths who had been walking past the premises at the moment of the explosion.
Ten people were killed in this explosion and dozens were injured, including many who lost limbs. Several casualties had been impaled by sections of wooden furniture; others had their clothes burned from their bodies. A paramedic called to the scene of this explosion later described the carnage as being reminiscent of a slaughterhouse; one fireman said that, upon seeing a writhing, "screaming torso", he had begged police to allow a television crew inside the premises to film the dead and dying at the scene, in the hope the IRA would see the consequences of their actions; however, the police refused this request, fearing the reprisals would be extreme.
One of those injured was 21-year-old Maureen Carlin, who had such extensive shrapnel wounds to her stomach and bowel she told her fiancé, Ian Lord (himself badly wounded in the explosion): "If I die, just remember I love you". Carlin was given the last rites, with surgeons initially doubtful she would live, although she recovered from her injuries.
The Tavern in the Town was a basement pub on New Street located a short distance from the Rotunda and directly beneath the New Street Tax Office. Patrons there had heard the explosion at the Mulberry Bush, but did not believe that the sound (described by one survivor as a "muffled thump") was an explosion.
Police had begun attempting to clear the Tavern in the Town when, at 20:27, a second bomb exploded there. The blast was so powerful that several victims were blown through a brick wall. Their remains were wedged between the rubble and live underground electric cables that supplied the city centre. One of the first police officers on the scene later testified that the scene which greeted his eyes was "absolutely dreadful", with several of the dead stacked upon one another, others strewn about the ruined pub, and several screaming survivors staggering aimlessly amongst the debris, rubble, and severed limbs. A survivor said the sound of the explosion was replaced by a "deafening silence" and the smell of burnt flesh.
