George Frederick Gilmore, a Protestant Irish republican and communist who becomes an Irish Republican Army leader during the 1920s and 1930s, dies in Howth, County Dublin, on June 29, 1985. During his period of influence, he attempts to shift the IRA to the political left, but alongside Peadar O’Donnell and Frank Ryan he is expelled for his efforts. After leaving the IRA, he attempts to unite Irish republicanism under the banner of the Republican Congress, but ideological debates split the group apart. Afterward, he removes himself from public life.
Born at Hillside Terrace in Howth, County Dublin, on May 5, 1898, Gilmore is the second son of Philip Gilmore, an accountant originally from County Antrim, and Fanny Angus. Despite his father primarily working for Unionist landlords, and being educated at home, George and his brothers Harry and Charlie all turn toward Irish republicanism. By 1916, Gilmore has become a member of Fianna Éireann, the Republican boy scouts, and later a member of the South County Dublin battalion of the Irish Volunteers.
Gilmore fights in the Irish Republican Army in the Irish War of Independence and in the Irish Civil War on the Anti-Treaty IRA side. During the civil war he is captured and imprisoned, but manages to escape custody in August 1923, the aftermath of which causes riots as the remaining prisoners are placed in solitary confinement.
Following the end of the civil war, Gilmore serves as the secretary of future Taoiseach Seán Lemass, as well alongside Frank Aiken. During the early 1920s, he, Lemass and Aiken regularly meet with the IRA army council to represent the emerging political leadership of Irish republicanism that coalesces as Fianna Fáil in 1926. The trio regularly sits opposite IRA leaders Frank Ryan, Peadar O’Donnell, and Seán Russell.
In October 1925, Gilmore and Lemass organise the escape of nineteen IRA prisoners from Mountjoy Prison in Dublin. As part of the jailbreak, Gilmore impersonates a member of Garda Síochána. None of the nineteen escapees are subsequently recaptured, and their escape serves as a major propaganda coup. However, the following month, Gilmore is involved in a riot that takes place on Armistice Day and he is subsequently arrested and sentenced to eighteen months in prison. He resists the entire duration; first resisting the arrest and then, once imprisoned, refusing to wear a prison uniform and going on hunger strike. Early in 1928, members of the IRA attack Mountjoy Prison where he is being held and shoot the warden after a story emerges that Gilmore had previously been the victim of a vicious beating by the guards. He is released in 1929 but re-arrested and re-imprisoned almost immediately, resulting in a retaliatory beating by the guards that leaves him unconscious.
Sometime between 1929 and 1930, Gilmore is sent by the IRA to Russia to receive military training and to seek aid.
Gilmore is arrested yet again upon his return to Ireland in April 1931, charged with having resisted arrest ten months previously. In October he tries to escape with the help of his brother Charlie and almost succeeds, using a plot involving mock pistols wrapped in silver to intimidate the guards. In the aftermath of the failed escape, his treatment in Arbour Hill Prison from 1931-32 is abysmal. He once again refuses to wear prison clothing because of his political status and remains naked in a windowless cell from October 1931 until February 1932. In June 1931, of a cache of weapons are discovered near his home at Killakee in the Dublin Mountains, which results in him and his brother Charlie being placed before a military tribunal which sentences him to five years in prison and Charlie to three (in 1932 Fianna Fail comes to power and the brothers are released). Neither recognises the authority of the court, with George stating, “I do not want anybody to think I excuse myself for such a charge as having arms, I am admittedly hostile to British imperialism and international capitalism.”
Gilmore’s fortunes are dramatically altered when Fianna Fáil emerges victorious in the 1932 Irish general election. In the aftermath, Frank Aiken, former Chief of Staff of the IRA and new Minister for Defence goes to see Gilmore on March 9 and on the next day all republican prisoners are released as part of a general amnesty. Thirty thousand supporters greet the prisoners at College Green, Dublin.
Finally out of long-term imprisonment, Gilmore is eager to resume working toward a socialist Ireland. He has supported Peadar O’Donnell’s shortlived socialist republican group Saor Éire from prison, but in the aftermath of its demise, he concludes that the group has spent too much time imagining what it might do if in government, and not enough time considering what the immediate aims of the IRA should be. With his close personal ties to their leadership, Gilmore has a positive view of Fianna Fáil, and at this point in time believes their goals differ little from his own and those of the IRA. Nevertheless, He encourages the IRA to not become too closely associated with Fianna Fáil, fearing the IRA will become a subservient body. He himself has ascended to the IRA’s army council upon his release, and in March 1932 is among representatives of the Army Council that liaises with Éamon de Valera about a possible partnership between the IRA and Fianna Fáil.
On August 14, 1932, Gilmore and fellow Irish republican T. J. Ryan are beaten badly, shot and wounded by plain-clothes members the Garda Síochána (Criminal Investigation Department) in Kilrush, County Clare. This incident is blamed on the police by an official Tribunal of Inquiry report one month later.
In March 1934, Gilmore, alongside Frank Ryan and Peadar O’Donnell, refuse to continue on as members of the IRA executive as part of a deepening rift over the direction of the IRA. Left-wing members of the IRA such as Gilmore, Ryan and O’Donnell insist that the IRA needs to tie their activity to social agitation in addition to their military aims, but this is a minority viewpoint, with the majority believing the IRA should have a “strictly military” outlook. The rift ultimately spirals into Gilmore, Ryan and O’Donnell being court-martialed and expelled in April.
In the aftermath, Gilmore works with Roddy Connolly, Nora Connolly O’Brien and Peadar O’Donnell to found the Republican Congress, a left-wing socialist Irish republican group. The group breaks up in 1935 over internal differences. Gilmore, Ryan and O’Donnell believe that the Republican Congress should be a united front, an alliance of all republican groups in Ireland. Roddy Connolly and other members of the Communist Party of Ireland believe that the Congress should be a vanguard party. A conference is held by the Republican Congress in Rathmines, Dublin, in September 1934 to vote on the issue. Before the vote is taken, Gilmore gives a speech in which he accuses Fianna Fáil of using republicanism as a means to promote Irish capitalism. When the votes are taken on whether the Republican Congress should be a united front or a vanguard party, Gilmore’s united front faction wins. However, supporters of the vanguard party concept such as Roddy Connolly immediately resign from the Congress in protest and walk out on the group. It proves to be a blow that the Congress never recovers from and the group is defunct by 1936. Gilmore makes a last-ditch effort to save the Congress by traveling to the United States to seek funds from Irish American groups but is not successful.
Upon the outbreak of the Spanish Civil War in July 1936, Gilmore and O’Donnell become supporters of the International Brigades. Both men travel to Spain personally, during which they are involved in a plane crash and Gilmore’s leg is broken.
Following the outbreak of World War II in September 1939, Gilmore writes an appeal pleading with the IRA to dump arms until the war in Europe is over and denounces them for flirting with fascism by seeking aid from Germany.
During the 1960s, when the republican movement once again moves to the left, Gilmore and O’Donnell are once again in demand as speakers and as writers in republican publications. In 1966, for the 50th anniversary of the Easter Rising, Gilmore releases a pamphlet entitled “Labour and the republican movement” in which he espouses the principles of James Connolly. Additionally, he appeals to young republicans not to repeat the mistake older republicans had made in being too rigid in their views and too short on policy.
Gilmore dies on June 29, 1985, at the age of 87, in a nursing home in Howth, County Dublin.
