Jim Lynagh, member of the East Tyrone Brigade of the Provisional Irish Republican Army (IRA), one of twelve children, is born on the Tully Estate, a housing estate in the townland of Killygowan on the southern edge of Monaghan, County Monaghan, on April 13, 1956.

Lynagh joins the Provisional Irish Republican Army in the early 1970s. In December 1973 he is badly injured in a premature bomb explosion, arrested, and spends five years in the Maze Prison. While imprisoned, he studies and becomes a great admirer of Mao Zedong. After his release from prison in 1979 he is elected as a Sinn Féin councillor for Monaghan, and holds this position until he is killed.

After his release from prison Lynagh becomes active in the IRA again, active with the Provisional IRA East Tyrone Brigade. He quickly becomes a unit commander and gradually builds up his ruthless reputation. After a series of Ulster loyalist attacks against Irish nationalist politicians in late 1980 and early 1981, he is suspected of involvement in an attack on the Stronge estate near Middletown, County Armagh, where the IRA murdered the retired Ulster Unionist Party Stormont speaker, Sir Norman Stronge, and his son James, a Royal Ulster Constabulary (RUC) officer, before burning down their home, Tynan Abbey, and shooting their way out through a police cordon.

Lynagh is known as “The Executioner” by the Royal Ulster Constabulary. He is arrested and interrogated many times by the Garda Síochána in County Monaghan but is never charged. During this period he devises a Maoist military strategy, aimed at escalating the war against the British state in Northern Ireland. The plan envisages the destruction of police stations and British Army military bases in parts of Northern Ireland to create “liberated” areas that will be thereby rendered under the domination of the IRA. In 1984 he starts co-operating with Pádraig McKearney who shares his views. The strategy begins materialising with the destruction of an RUC police station in Ballygawley in December 1985 which kills two police officers, and in The Birches in August 1986.

Lynagh is killed by the British Army’s Special Air Service on May 8, 1987 during an attack on the isolated rural part-time police station at the small County Armagh village of Loughgall, the third such attack that he had taken part in. During the incident the IRA detonates a 200-lb. bomb, and attacks the station with automatic weapons, and in the process are ambushed by the British Army which is lying in wait for them, having been forewarned of the IRA operation. All eight of the IRA attacking force are killed in the exchange of fire, the British forces involved incurring no fatalities. The incident subsequently becomes known as the Loughgall ambush.

At the time of his death, Lynagh is living in a flat on Dublin Street in Monaghan. He is buried at St. Joseph’s Cemetery (Latlurcan Cemetery) in Monaghan. During his funeral, as his coffin is carried through the village of Emyvale, Irish Garda Síochána officers are attacked by the crowd of mourners after they pursue three gunmen who had fired a volley over his coffin.
