Seán McGarry, a 20th-century Irish nationalist and politician, dies suddenly on December 9, 1958, of a heart attack at his son’s home at 44 Richmond Avenue, Monkstown, County Dublin. A longtime senior member of the Irish Republican Brotherhood (IRB), he serves as its president from May 1917 until May 1918 when he is one of a number of nationalist leaders arrested for his alleged involvement in the so-called German Plot.
McGarry is born at 17 Pembroke Cottages, Dundrum, Dublin, on August 2, 1886. An active member of the Irish Republican Brotherhood, he is a close friend of Bulmer Hobson and is frequently arrested or imprisoned by British authorities for his activities with the IRB during the early 1900s. He participates in the 1916 Easter Rising as an aide-de-camp to Tom Clarke and is sentenced to eight years penal servitude for his role in the failed rebellion.
McGarry is sent to Frongoch internment camp in Wales but is eventually released. He assists Michael Collins in his efforts to reorganise the Irish Republican Brotherhood and, at the Volunteer Executive Meeting held in late 1917, he is elected General Secretary of the Irish Volunteers.
On the night of May 17, 1918, McGarry is arrested, along with seventy-three other Irish nationalist leaders, and deported to England, where they are held in custody without charge. The day following their arrest, he and the others are charged with conspiring “to enter into, and have entered into, treasonable communication with the German enemy.” In his absence, Harry Boland is selected for the Supreme Council and becomes his successor as president of the IRB.
McGarry is only imprisoned a short time when he takes part in the famous escape from Lincoln Jail with Seán Milroy and Éamon de Valera on February 3, 1919. He and Milroy manage to smuggle out a postcard, a comical sketch of McGarry to his wife, allowing a copy of the key to their cell to be made. They are later assisted by Harry Boland and Michael Collins who await them outside the prison.
A month later, McGarry gives a dramatic speech at a Sinn Féin concert held at the Mansion House, Dublin, before going into hiding.
Throughout the Irish War of Independence, McGarry serves as a commander and is eventually elected to Second Dáil in the 1921 Irish elections as a Sinn Féin Teachta Dála (TD) representing Dublin Mid. He, like the majority of those in the Irish Republican Brotherhood, supports the Anglo-Irish Treaty and is involved in debates against de Valera during the controversy, most especially discussing the status of Sinn Féin as a political entity.
McGarry is re-elected as a Pro-Treaty Sinn Féin TD in the 1922 Irish general election, siding with the Free State government during the Irish Civil War. Liam Lynch and other members of the anti-Treaty Irish Republican Army plan the assassination of McGarry among other TDs supporting the Public Safety Bill. As one anti-Treaty volunteer tells Ernie O’Malley, “Seán McGarry was often drunk in Amiens Street and the boys wanted to shoot him and the Staters there, but I wouldn’t let them.”
On December 10, 1922, shortly before the first meeting of the Free State parliament, a fire is deliberately set by irregulars (anti-Treatyites) at McGarry’s family home. His seven-year-old son, Emmet, is badly burned and dies as a result. McGarry is one of four targeted by anti-Treatyites during the December Free State executions. De Valera publicly denounces the attack.
McGarry is re-elected as a Cumann na nGaedheal TD in the 1923 Irish general election for Dublin North. Dissatisfied and disillusioned with Cumann na nGeadhael, he resigns from the party after the Irish Army Mutiny and joins Joseph McGrath‘s National Party. He resigns his seat in October 1924.
After retiring from politics, McGarry works for the Irish Hospitals Trust, writes articles for newspapers and journals, and engages in broadcasting. After residing from the mid-1920s at several addresses in Dún Laoghaire, from 1938 he lives at 25 Booterstown Avenue, Blackrock, Dublin. With his wife Tomasina he has two sons and one daughter. He dies suddenly on December 9, 1958, of a heart attack in his son’s home at 44 Richmond Avenue, Monkstown, County Dublin.
