By mid-1922, the Anti-Treaty IRA is in retreat after the Anglo-Irish Treaty has split the IRA into pro- and anti-Treaty factions. Lynch, a staunch opponent of the Treaty, had been appointed Chief of Staff in April 1922 to unify the Anti-Treaty leadership. Fermoy, a key County Cork town, has been a republican stronghold since the Irish War of Independence, but by August 1922, it is under increasing pressure from Free State troops.
Fermoy’s surrender is not a single battle but a series of engagements and encirclements. Free State forces have been systematically dismantling republican positions in County Cork, and Fermoy’s defenses are proving unsustainable. Lynch, recognizing the strategic and tactical inevitability of defeat, orders the withdrawal of IRA forces from the town. This move effectively ends the IRA’s presence in Cork city and its surrounding areas.
Fermoy’s fall is a strategic loss as it removes the last major republican-held town in County Cork, cutting off supply lines and communication with other Anti-Treaty strongholds. The abandonment underscores the crumbling of the Anti-Treaty position and the Free State’s consolidation of control over the south. It also results in a leadership shift as Lynch’s decision reflects his pragmatic approach — while ideologically opposed to the Treaty, he seeks to avoid further bloodshed and preserve the IRA’s remaining forces.
Following Fermoy’s fall, Lynch continues to command the Anti-Treaty IRA from the south, but without a major base. His leadership soon faces further challenges, culminating in his death on April 10, 1923, during a pursuit by Free State troops in the Knockmealdown Mountains.
In short, the abandonment of Fermoy on August 11, 1922, is both a military and symbolic end to the Anti-Treaty IRA’s last stronghold in County Cork, accelerating the end of the Irish Civil War.
The killing is widely seen as a political act, with Dunne and O’Sullivan claiming to have acted in defence of Irish nationalist principles, blaming Wilson for the “Orange Terror” and the deployment of the Ulster Special Constabulary (USC). Some historians suggest the assassination may have been intended to pressure Michael Collins to attack the Four Courts garrison, though no conclusive evidence of orders was ever established.
After the shooting, Dunne escapes but O’Sullivan is captured by a hostile crowd. Dunne attempts to rescue him but is himself arrested after wounding two police officers and a passerby. Both are tried quickly, found guilty after just three minutes of deliberation, and sentenced to death by Justice Montague Shearman.
Despite petitions from 45,000 people and appeals from figures like George Bernard Shaw, both men are executed on August 10, 1922, and buried within the prison grounds.
The executions are a major political flashpoint. It is only after the abolition of hanging that the law is changed and Joseph’s brother, with the assistance of the Irish National Graves Association, is able to arrange for the bodies of the two men to be repatriated to Ireland.
Dunne’s trial speech, reprinted in the Irish Independent, remains a notable piece of republican political rhetoric, framing the act as a necessary stand for Irish rights.

On the morning of August 8, 1922, the National Army of the Irish Free State launches a decisive seaborne assault on Cork, County Cork, the Free State’s second largest city, which is held by anti-Treaty Irish Republican Army (IRA) forces. The operation begins at Passage West, a ferry port and fishing village on the estuary of the River Lee, where the steamshipArvonia docks. The anti-Treaty IRA garrison in Cobh across the bay opens fire with three machine guns, but the National Army troops on deck respond with silence, surprising the sentry who had fired a warning shot.
Over 200 pro-Treaty soldiers disembark, quickly securing the town. The Arvonia is unloaded with 450 troops, an 18-pounder field gun, and several armoured cars. Simultaneously, landings are made at Youghal in east County Cork and Union Hall near Skibbereen in west County Cork, disgorging another 350 troops. This is part of Michael Collins’s plan to seize Cork and end the Irish Civil War swiftly.
Cork is a flashpoint of the Treaty split. While the majority of IRA fighters in the county oppose the Anglo-Irish Treaty, the majority of civilians support it. There are also strong neutral tendencies and peace calls within Cork’s civil and military communities. The Free State’s move aims to break the “Munster Republic” stronghold and force a rapid political settlement.
The landing marks the start of the Battle for Cork, which intensifies over the next days. National Army forces advance toward Cork city, encountering fierce resistance from anti-Treaty IRA positions in areas like Rochestown, Oldcourt Wood, and Garryduff. The fighting is brutal, with estimates of up to 20 fatalities and many wounded. The conflict also produces poignant moments, such as the death of Free State soldier Flood, shot by a former Irish War of Independence comrade, Frank O’Donoghue.
The August 8 landings are the decisive military stroke of the Irish Civil War. They re-take Cork for the Irish Free State, dismantle the Munster Republic, and end the conventional phase of the conflict, paving the way for a prolonged guerrilla war until the anti-Treaty side’s defeat. The event remains a key moment in Irish revolutionary history, remembered for its scale, the use of armoured units, and the deep divisions it exposes in Cork.
Free State Army officers, acting on intelligence that a meeting is in progress at Hudson’s home, leave Portobello Barracks (now Cathal Brugha Barracks) in two cars. As they approach, a Fianna Éireann member on sentry duty blows his whistle, alerting the occupants. The group scatters through the back garden, and Hudson is injured, dropping his weapon. A Free State Army officer approaches him at point‑blank range and shoots him.
At the time of his death, Hudson reportedly has his hands up, and he makes a deathbed declaration to that effect. An automatic pistol is found with him, but it is loaded with the wrong calibre ammunition, suggesting he could not have fired it.
Hudson’s killing occurs during a period of intense guerrilla warfare in south County Dublin. The area had seen earlier clashes between pro‑ and anti‑Treaty forces, and by August 1922, anti‑Treaty IRA columns are active in Dún Laoghaire and surrounding towns. His death is part of a broader campaign by Irish Free State forces to suppress anti‑Treaty resistance in the region.
Hudson’s case is remembered as one of the more controversial incidents of the Irish Civil War, reflecting the brutality and political divisions of the conflict. His father, Joseph Hudson Snr, was also an IRA volunteer.
In the early morning of August 5, 1922, during the Irish Civil War, around 200 anti-Treaty Irish Republican Army (IRA) volunteers are mobilised around Dublin. Their mission is to isolate the city by destroying all bridges and road crossings leading into it, cutting off Free State forces and supplies.
The anti-Treaty IRA, opposed to the Anglo-Irish Treaty and the newly established Irish Free State, aim to dismantle the stone bridges over Dublin’s rivers and canal, lay explosives on road and railway bridges, dig trenches in roads to block movement and scout the surrounding countryside for Free State troops.
They are organised in groups of 5–40, some armed with handguns and grenades, others with explosives and tools like spades and picks. Parties are sighted in the hills south of the city (from Kilakee to Roundwood) and across villages north of Dublin (from Raheny to Blanchardstown).
The Free State’s intelligence service intercepts the plan when Liam Clarke, a captured anti-Treaty officer, reveals the details to Free State Intelligence officers. This intelligence allows the Free State to anticipate and counter the operation.
On August 6, Free State forces move quickly to intercept the IRA. They capture 31 anti-Treaty irregulars at Glencullen Bridge (pictured) and later take 104 fighters in County Dublin, including officer Pat Sweeney. These actions cripple the remnants of the anti-Treaty IRA in Dublin and prevent the city from being isolated.
The “Bridges Job” is a major anti-Treaty attempt to cut off Dublin during the Irish Civil War. Its failure marks a turning point, as Free State forces can now move freely into the city, accelerating the end of the conventional phase of the conflict.
On the morning of August 3, his body is discovered in a field at Maher’s farm, close to Jamestown Road in Finglas. He had been shot dead. The exact details of his capture and killing are later ordered to be destroyed in 1932 by the Pro-Treaty government.
McEntee is buried in the Republican Plot at Glasnevin Cemetery, Dublin. A National Graves Association memorial plaque is placed there around 1932 and is maintained by the Fianna Sluagh in Finglas during the 1950s–60s. In 2023, his family and community commemorate the centenary of his death, remembering him as a skilled carpenter, devoted father, and soldier of the Irish Citizen Army.
In summary, Henry McEntee’s abduction and murder in August 1923 are part of the violent post-war repression of anti-Treaty IRA members, and his case remains a poignant example of the personal toll of Ireland’s Civil War.
At the start of the Irish Civil War in June 1922, the Free State controls only Dublin. Anti‑Treaty forces, forming the so‑called Munster Republic, hold Cork, Limerick, and Waterford, along with much of the west. Waterford’s republican garrison has fortified the city, dismantled the drawbridge’s control equipment, and isolated the port by removing wireless and other communications.
On July 16, republican forces learn that Free State troops ae moving toward Waterford. They raise the drawbridge early and move vessels from the Kilkenny side to the Waterford side. On July 18, Prout’s column is spotted from Sallypark Hill, prompting republican machine gun and rifle fire. A Free State volunteer, Costeloe, is wounded and later dies.
From July 19, sniping continues across the River Suir. On July 19, the Free State brings the 18‑pounder artillery into position overlooking the city, bombarding republican positions. The republicans hold key buildings such as the Adelphia Hotel, Country Club, and Reginald’s Tower.
By July 21, Free State forces cross the River Suir downstream at Gyles Quay, enter the city, and drive out republican troops from their positions. The drawbridge on Redmond Bridge is lowered by hand, and republican reinforcements from Cork and Tipperary either withdraw or do not engage. The Free State takes Waterford on July 21, 1922, ending the republican hold on the city.
Two anti‑Treaty volunteers, Maurice McGrath and John “Bonny” Boyle, are killed. Two Free State soldiers, Sergeant James Howlett and Michael Costelloe, are killed. At least six civilians are killed, including Joseph Dwan, William Long, and a 10‑year‑old girl. Many civilians are wounded.
The fall of Waterford marks a key Free State victory in the conventional phase of the Irish Civil War, contributing to the re‑capture of major southern cities and paving the way for the later guerrilla phase.

The Irish Civil War (June 1922–May 1923) pits pro-Treaty Free State forces against anti-Treaty IRA units who oppose the Treaty’s terms. Aiken is a key republican commander, and Dundalk is a stronghold for his forces. By mid-July 1922, Free State troops have taken several towns, and Dundalk is next in line for reoccupation.
General Hogan’s forces enter Dundalk, engaging republican snipers and irregulars. The attack targets the Gaol, where Aiken and many of his men are held. The Free State troops overpower the defenders, leading to Aiken’s arrest and the capture of a significant portion of the Fourth Northern Division.
Aiken and about 104 other prisoners escape on July 27, 1922, through a narrow gap in the jail wall, later dubbed the “Hole in the Wall.” This escape is a major republican success, temporarily reoccupying Dundalk. However, Free State forces retake the town on August 14, 1922, and the jail remains under military control until 1924.
The capture is significant as it marks a turning point in the Free State’s campaign in County Louth, weakening republican resistance in the area. Aiken’s arrest underscores the Free State’s determination to dismantle anti-Treaty leadership. The events in Dundalk become a symbol of republican resilience, as the escape through the “Hole in the Wall” is widely reported and commemorated.
In summary, the July 16, 1922, capture of Frank Aiken in Dundalk is a decisive Free State action in the Irish Civil War, leading to a notable republican escape and a prolonged military standoff in the town.

Wexford had been relatively quiet during the Irish War of Independence, but the Treaty split in 1921 creates deep divisions. The South Wexford Brigade under Thomas O’Sullivan is overwhelmingly anti-Treaty, while the North Wexford Brigade under Joseph Cummins is nominally pro-Treaty but contains a significant anti-Treaty minority. This division means that when the Irish Civil War breaks out on June 28, 1922, Wexford becomes one of the most violent counties, with Republican forces rapidly moving to secure strategic towns.
On July 4, anti-Treaty IRA units, including Tipperary volunteers and escaped Four Courts fighters, move into Enniscorthy, take over key positions and force the surrender of Free State troops. In the opening fighting, three combatants are killed — two IRA and one National Army — marking the first major Republican gains in the county. James Roche, an IRA member, is fatally wounded in an accident outside Newtownbarry (now Bunclody) on the same day, one of several accidental deaths among IRA personnel in Wexford during the Irish Civil War.
The capture of Enniscorthy is part of a broader Republican offensive in County Wexford in early July 1922. However, the balance of power shifts quickly. By July 6, a large relief force of government troops sets out from Dublin to retake the town. This marks the beginning of a protracted and bloody campaign in County Wexford, which sees the county become one of the most violent in the Irish Civil War.
In summary, the capture of Enniscorthy on July 4, 1922, is a significant Republican victory in County Wexford, driven by the Treaty split and reinforced by external IRA units. It reflects the rapid escalation of violence in the county and sets the stage for a prolonged and destructive phase of the Irish Civil War in County Wexford.

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 TaoiseachSeán 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.
