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.
By mid-July 1922, the Free State has re-taken counties Limerick and Waterford, but the IRA still controls counties Cork and Kerry, as well as much of the west under Liam Lynch’s command. A purely land-based advance into these areas risks long, attritional battles. Dalton’s plan is to create a second front by landing troops along the County Kerry and County Cork coasts, isolating republican strongholds like Tralee.
The SS Lady Wicklow carries 450 soldiers of the Dublin Guardbrigade under Paddy Daly, along with a field gun and an armoured car nicknamed the Ex-Mutineer. The Dublin Guards are considered the most disciplined and politically reliable unit in the Army, and Daly is one of Michael Collins’ trusted lieutenants. The landing is intended to secure Fenit as a base for an amphibious assault on Tralee, a key republican stronghold.
The surprise attack catches the IRA forces off guard, taking their left flank in the rear. The Free State quickly advances, and by the following days, much of County Kerry is freed from republican control. The operation is part of a broader offensive that culminates in the capture of Tralee on August 2, one of the bloodiest single days of combat for the National Army.
While the initial landings are successful, the IRA mounts counterattacks over August and September, regaining some ground. However, the Free State’s superior resources, better equipment, and lack of popular support for the republicans allows them to consolidate control in County Kerry over time. The Fenit landing is a turning point, shifting the momentum in favour of the Free State and contributing to the eventual republican defeat in the Irish Civil War.
In summary, the August 2, 1922, naval landing at Fenit is a bold, surprise amphibious operation that disrupts republican defenses, opens County Kerry to Free State advance, and alters the course of the Irish 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 Citizen Army also becomes involved in the battle, supporting the anti-Treaty IRA in the O’Connell Street area. The fighting begins with an assault by Provisional Government forces on the Four Courts building and ends in a decisive victory for the Provisional Government.
On April 14, 1922, about 200 Anti-Treaty IRA militants, with Rory O’Connor as their spokesman, occupy the Four Courts in Dublin, resulting in a tense stand-off. They want to spark a new armed confrontation with the British, which they hope will bring down the Anglo-Irish Treaty, unite the two factions of the IRA against their former common enemy and restart the fight to create an all-Ireland Irish Republic. At the time the British Army still has thousands of soldiers concentrated in Dublin, awaiting evacuation.
Winston Churchill and the British cabinet have been applying pressure on the Provisional Government to dislodge the rebels in the Four Courts, as they consider their presence a violation of the Treaty. Such pressure falls heaviest on Michael Collins, President of the Provisional Government Cabinet and effective head of the regular National Army. Collins, a chief IRA strategist during the War of Independence from Britain, has resisted giving open battle to the anti-Treaty militants since they occupied Four Courts in April. His colleagues in the Provisional Government Cabinet, including Arthur Griffith, agree that Collins must mount decisive military action against them.
In June 1922 the Provisional Government engages in intense negotiations with the British Cabinet over a draft Constitution that seeks to avert the impending civil war. They particularly seek to remove the requirement of an oath to the British Crown by all members of the Dublin government, a key point of contention with anti-Treaty partisans. However, the conservative British Cabinet refuses to cooperate. The pro-treaty element of Sinn Féin wins the elections on June 16.
Following the assassination of Sir Henry Wilson in London on June 22, 1922, and the arrest by Four Courts troops of National Army Deputy Chief of Staff Gen. J. J. “Ginger” O’Connell, British pressure on the Provisional Government intensifies. The British now threaten to invade and re-occupy all of Ireland. On June 27 the Provisional Government Cabinet agrees on an ultimatum to the Four Courts garrison to evacuate or face immediate military action.
Churchill offers a loan of British artillery for use by the National Army, along with 200 shells from their store of 10,000 at Kilmainham, three miles away. It is possible that some British special troops are also covertly loaned. Two 18-pounder field guns are placed on Bridge Street and Winetavern Street, across the River Liffey from the Four Courts complex. After an ultimatum is delivered to the anti-Treaty garrison in the early hours of June 28, the National Army commences the bombardment of Four Courts.
No authoritative record exists regarding the order to commence bombardment. Historians tend to attribute the order to Collins, but some biographers dispute this. Anti-Treaty survivors allege that they are preparing for an 8:00 a.m. evacuation when the bombardment begins at 4:00 a.m.
Inside the building are 12 members of the Irish Republican Army Executive, including Chief of StaffJoe McKelvey, Director of Engineering Rory O’Connor, Quartermaster General Liam Mellows and Director of Operations Ernie O’Malley. The garrison consists of roughly 180 men drawn from the 1st and 2nd Battalions of the IRA’s 1st Dublin Brigade, commanded by Commandant Paddy O’Brien, armed for the most part only with small arms apart from one captured armoured car, which they name “The Mutineer.” The members of the IRA Army Executive are the political leaders of the garrison but serve as common soldiers under the command of O’Brien. The Anti-Treaty side fortifies the Four Courts to some extent, planting mines around the complex and barricading the doors and windows, but their leadership orders them not to fire first, in order to retain the moral high ground, and so the Free State troops are allowed to surround the Four Courts.
After the first day’s bombardment proves ineffective, the British give the Free State two more 18-pounder cannon and proffer 60-pounder howitzers along with an offer to bomb the Four Courts from the air. Collins turns down the latter two offers because of the risk of causing heavy civilian casualties. On June 29, Free State troops storm the eastern wing of the Four Courts, losing three killed and 14 wounded and taking 33 prisoners. The republicans’ armoured car is disabled and abandoned by its crew. Early the next day O’Brien is injured by shrapnel and O’Malley takes over military command in the Four Courts. By this time the shelling has caused the Four Courts to catch fire. In addition, orders arrive from Oscar Traynor, the anti-treaty IRA commander in Dublin, for the Four Courts garrison to surrender, as he cannot reach their position to help them. O’Malley rules this order invalid, as the Four Courts is a GHQ operation. However, in view of the rapidly deteriorating situation, at 3:30 p.m. on June 30, O’Malley surrenders the Four Courts to Brigadier GeneralPaddy Daly of the Free State’s Dublin Guard unit. Three of the republican garrison die in the siege.
Several hours before the surrender, the Public Record Office of Ireland (PRO) block located in the western block of the Four Courts, which is used as an ammunition store by the Four Courts garrison, is the centre of a huge explosion, destroying Irish state records going back to the Anglo-Norman conquest. Forty advancing Free State troops are badly injured. Assigning blame for the explosion remains controversial. It is alleged by the National Army Headquarters that the Anti-treaty forces deliberately booby-trapped the PRO to kill advancing Free State troops. Tim Healy, a government supporter, later claims that the explosion is the result of land mines laid before the surrender, which explode after the surrender. However, a study of the battle concludes that the explosion is caused by fires ignited by the shelling of the Four Courts, which eventually reach two truckloads of gelignite in the munitions factory. A towering mushroom cloud rises 200 feet over the Four Courts.
At this stage in the battle troops on each side still have a sense of kinship with the other, as most of them had fought together in the Irish Republican Army during the Irish War of Independence. By appealing to friends on the Free State side, several anti-Treaty leaders among the Four Courts garrison, notably Ernie O’Malley and Seán Lemass, escape from captivity to continue the fight.
Despite the Free State force’s success in taking the Four Courts, fighting continues in Dublin until July 5. On June 29 anti-Treaty IRA units from the Dublin Brigade led by Oscar Traynor have occupied O’Connell Street, part of Parnell Square, York Street and some of other locations to try to distract Free State attention from their attack on the Four Courts. Not all the IRA units in the capital are prepared to fight against the new Irish government, however, and their numbers are probably about 500 throughout the city. Their numbers are supplemented by about 150 Citizen Army men and women who bring with them arms and ammunition dumped since the insurrection of Easter 1916.
The republicans occupy the northeastern part of O’Connell Street, with their strong point at “the block,” a group of buildings that the Anti-Treatyites had connected by tunneling through the walls. They had also taken over the adjoining Gresham, Crown, Granville and Hammam hotels. Their only position on the western side of the street is in the YMCA building. Additionally, they have an outpost south of the River Liffey at the Swan Pub on Aungier Street. Oscar Traynor apparently hopes to receive reinforcements from the rest of the country, but only Anti-Treaty units in Belfast and Tipperary reply and both of them arrive too late to take part in the fighting.
The Provisional Government troops, commanded by General Tom Ennis, start by clearing out the outlying anti-treaty garrisons, which is accomplished by July 1. They then draw a tighter cordon around O’Connell Street. Artillery is used to drive the Anti-Treaty fighters out of positions on Parnell Street and Gardiner Street, which gives the Free State troops a clear field of fire down O’Connell Street.
The republican outpost in the YMCA is eliminated when Free State troops tunnel underneath it and detonate a bomb. Traynor’s men in “the block” hold out until artillery is brought up, under the cover of armored cars, to bombard them at point-blank range. Incendiary bombs are also planted in the buildings. Traynor and most of his force make their escape when the buildings they are occupying catch fire. They mingle with civilian crowds and make their way to Blessington.
Left behind is Republican leader Cathal Brugha and a rear guard of 15 men, who stay behind in the Hammam Hotel after Traynor, and most other IRA men have left. At 5:00 p.m. on July 5, when the fires make the hotel untenable, Brugha orderes his men to surrender. He, however, stays behind, only to emerge from the building alone, armed with a revolver. He is shot in the thigh by Free State troops and dies later from blood loss. There are some further sporadic incidents of fighting around the city as Free State troops disperse anti-treaty IRA groups.
Cathal Brugha is the last casualty in the Battle of Dublin, which costs the lives of at least 80 people (15 anti-Treaty IRA Volunteers, 29 National Army soldiers, one British Royal Air Force serviceman and 35 civilians) and over 280 wounded. In addition, the Free State takes over 450 Republican prisoners. The high civilian casualties are doubtless the result of the use of heavy weapons, especially artillery, in a densely populated urban area.
When the fighting in Dublin dies down, the Free State government is left firmly in control of the Irish capital and the anti-treaty forces disperse around the country. Roundups after the fighting result in more Republican prisoners and the death of prominent anti-Treaty activist Harry Boland who is shot dead in Skerries, Dublin, on July 31.
Oscar Traynor, Ernie O’Malley and the other anti-Treaty fighters who escape the fighting in Dublin regroup in Blessington, around 30 km southwest of the city. An anti-Treaty IRA force from County Tipperary had arrived there but too late to participate in the Dublin fighting. Instead, this force heads south and takes a string of towns, including Enniscorthy and Carlow, but quickly abandons them when faced with superior Free State forces. Most of the Republicans then retreat further south to the so-called Munster Republic, territory southwest of a line running from Limerick to Waterford. This in turn is taken by the Free State in an offensive from July to August 1922.
Four of the Republican leaders captured in the Four Courts, Rory O’Connor, Liam Mellows, Joe McKelvey and Richard Barrett, are later executed by the government in reprisal for the Anti-Treaty side’s killing of TDSeán Hales. The street where Cathal Brugha is killed is later renamed Cathal Brugha Street in his honour.
