On August 29, 1922, six Irish Free State soldiers are killed in three separate ambushes, reflecting the intense and deadly engagements of the early Irish Civil War period.
The Irish Civil War (June 1922 – May 1923) erupts following the signing of the Anglo-Irish Treaty in 1921, which creates the Irish Free State. Pro-Treaty forces, forming the National Army, clash with anti-Treaty Irish Republican Army (IRA) elements refusing to accept the Treaty. This conflict includes both conventional and guerrilla phases, with August 1922 marking the end of the conventional campaign as Free State forces advance to secure towns in the south and southwest.
On this day, six Free State soldiers are killed in three distinct ambushes. Two soldiers died in Tullamore, County Offaly, one in Macroom, County Cork, and two in an ambush and firefight between Killorglin and Tralee, County Kerry. In Tullamore, Lieutenant Matthew Cullen of the 3rd Southern Division is fatally shot near Bonaterrin Hill, while Lieutenant Leahy is seriously wounded in the same attack. These ambushes are carried out by anti-Treaty forces and demonstrate the difficulties the National Army faces while attempting to secure supply routes and rural areas, even after major towns have fallen under Free State control.
These casualties underscore the dangers posed by guerrilla tactics, including ambushes, during the Irish Civil War. Free State soldiers are often young and inexperienced, and many fatalities occur in such rural confrontations. Despite these losses, the Free State maintains strategic momentum, continuing the offensive that eventually consolidates the new government’s control.
Overall, the Irish Civil War results in roughly 1,426 deaths in the Free State counties, with the National Army sustaining substantial casualties in actions like these ambushes. The conflict’s fatal events, including Tullamore on August 29, illustrate both the human cost of the war and the localized intensity of battles beyond major urban centers.
In summary, August 29, 1922, represents a notable moment in Irish Civil War history, highlighting the lethal impact of ambushes on Free State forces and the challenges of combatting anti-Treaty operations in rural Ireland. These events contribute to the broader struggle to establish the Irish Free State’s authority.
By mid-August 1922, the Irish Free State, under Michael Collins, has launched a decisive offensive to re-take towns and strongholds in the south and west. The anti-Treaty IRA, led by figures such as Liam Lynch, has been holding areas like County Cork, County Limerick, and much of County Kerry, including Killarney, in defiance of the Anglo-Irish Treaty. The Free State’s campaign aims to consolidate control over the territory and end the conventional phase of the war.
The ambush at Glenflesk is one of several IRA actions in County Kerry during this period. It occurs as Free State forces advance in the west, seeking to secure supply lines and isolate remaining anti-Treaty strongholds. The Anti-Treaty IRA, using guerrilla tactics, targets convoys and patrols to disrupt Free State operations.
While the exact casualty figures for this specific engagement are not detailed in the available records, such ambushes are part of a wider pattern of republican resistance. In County Kerry alone, Free State forces suffer multiple engagements in August, including a sniper kill at Tralee and ambushes on supply columns.
The Glenflesk ambush reflects the shift from conventional warfare to mobile, hit-and-run tactics by the anti-Treaty IRA after the Free State’s conventional offensives begin. County Kerry remains a contested area, with Killarney and surrounding towns serving as republican bases. Ambushes like this one aim to delay Free State advances and protect supply routes. While the Free State’s overall campaign succeeds in capturing major towns by late August, such ambushes prolong the conflict and keep republican forces active until the “dump arms” order in 1923.
In summary, the Glenflesk ambush of August 27, 1922, is a localized but significant IRA resistance action in County Kerry, emblematic of the guerrilla warfare that follows the Free State’s conventional offensives and contributes to the prolonged nature of the Irish Civil War.

Humbert is the eldest of six children of Jean-Joseph Humbert, a farmer and trader, and Catherine (née Privat), who dies when he is three years old. From a modest rural background, he works briefly as a hatter and rabbit hunter before entering the military in July 1789 amid the early stages of the French Revolution.
In 1796, Humbert is assigned to prepare for an expedition to Ireland. In the ill-fated Expédition d’Irlande, his ship Droits de l’Homme is wrecked off the Bay of Audierne in January 1797, but he survives. In 1798, he leads about 1,000 French troops to Ireland, landing at Killala. His forces fight and win at Ballina and the Races of Castlebar, proclaiming a Republic of Connacht before being defeated and captured at the Battle of Ballinamuck. He is exchanged for British prisoners.
In 1810, Humbert emigrates to New Orleans, where he becomes acquainted with French pirate Jean Lafitte. He joins the Buenos Aires rebellion in 1814 before returning home. In 1815, he fights the British at the Battle of New Orleans in the War of 1812, earning thanks from General Andrew Jackson. He later lives as a schoolteacher in New Orleans until his death on January 3, 1823.
Humbert’s career spans revolutionary France, Napoleonic campaigns, and post-Napoleonic adventures, making him a notable figure in late 18th- and early 19th-century military history.
By mid-1922, the Irish Civil War begins after the Anglo-Irish Treaty splits the IRA into pro- and anti-Treaty factions. The 4th Northern Division, based in counties Armagh, Down, and Louth, is one of the most formidable Anti-Treaty units in the region. Frank Aiken, a veteran IRA commander, has rebuilt this division during the Truce period, using it for guerrilla operations and border raids.
The Free State Army, under the National Army, is consolidating control in southern and midland counties, while Anti-Treaty forces focus on border counties to prevent Free State expansion and to maintain resistance.
The August 16 assault on Dundalk is a border raid aimed at disrupting Free State supply lines and communications, isolating and weakening Free State positions in the Louth area and demonstrating Anti-Treaty strength to other IRA units and the wider population. They use two mines to breach the walls of the barracks and temporarily take over the town.
Seven Free State soldiers are killed and fifteen are wounded. Two republicans are killed, accidentally by one of their own mines, and thirty are wounded. About 240 republican prisoners are freed from the prison and 400 rifles are taken. Aiken, however, does not try to hold the town and, while in possession of it, calls for a truce in a meeting in the town square.
While the attack is significant in symbolic terms, it does not achieve a decisive strategic breakthrough. Free State forces are able to regroup and counterattack, and the operation highlights the challenges Anti-Treaty units face in sustaining large-scale offensives against a better-equipped and more mobile National Army.
The raid exemplifies the “war along the border” strategy, where Anti-Treaty forces target Free State-held border towns and infrastructure. Aiken’s leadership as commander of the 4th Northern Division underscores his reputation as a skilled guerrilla leader. The attack reflects the early Civil War pattern of small-scale, mobile raids by Anti-Treaty forces against Free State-held towns and garrisons.
In summary, the August 16, 1922, Dundalk attack is a notable Anti-Treaty IRA operation that showcases the 4th Northern Division’s capabilities but also the limitations of their conventional-style assaults against the Free State’s growing military presence.

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.
The 3rd Tipperary Brigade is one of the most active IRA units in mid-Munster, operating mainly in southern County Tipperary and parts of County Limerick. It is known for its mobility and effectiveness in ambush tactics. Dinny Lacey, as a senior commander, is instrumental in planning and executing these operations.
While the exact details of the July 31 operations are not fully documented in the provided sources, the date falls within a period of intense IRA activity in the region. In July 1920, the IRA has already conducted several notable actions in County Tipperary, including the Newtown Cross Ambush on July 2, 1920, in which Sergeant Robert Tobin is killed and Constable Brady is wounded, and the Dingle Ambush on July 13, 1920, in which two Royal Irish Constabulary (RIC) men are killed.
These earlier incidents show that IRA forces in southern County Tipperary are actively targeting RIC patrols and outposts, and the July 31 ambushes are likely part of a similar pattern of harassment and disruption.
Successful ambushes like these weaken British control in rural County Tipperary, disrupt police and military operations, demonstrate the IRA’s ability to strike quickly and effectively in difficult terrain and contribute to the overall IRA strategy of attrition and intimidation.
The brigade continues to operate under Lacey’s leadership until his death in 1923 during the Irish Civil War. His tactics in 1920 help establish the 3rd Tipperary Brigade as a key player in the IRA’s campaign in the south.
In summary, on July 31, 1920, Dinny Lacey’s IRA unit in southern County Tipperary executes two successful ambushes, continuing a series of targeted attacks that are central to the IRA’s guerrilla campaign against British forces in the region.
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.

Barry returns to Bandon in early 1919. He describes in his guerilla days in Ireland a Damascus-like conversion to Irish nationalism on hearing of the Easter Rising while with the Mesopotamian expeditionary force, but he is only accepted into the IRA with considerable caution. Initially tested in intelligence and training work, in mid-1920 he takes charge of the new brigade flying column, which is used both to train officers and to stage offensive actions.
Barry adapts his military experience successfully to the demands of guerrilla warfare, becoming the most famed of column leaders during the Irish War of Independence. In his memoirs, he pours scorn on the obsession of many with military titles and orthodox procedure, complaining of a “paper army.” He stresses the need for spontaneity, initiative, and knowledge of local conditions. “The reality,” he writes, “was a group of fellows, mostly in caps and not-too-expensive clothing, wondering how to tackle their job and where they would sleep that night or get their supper.” (The Reality of the Anglo–Irish War (1974)). He well realises that the war’s character does not permit any close control from the IRA’s GHQ in Dublin, hence increasing the importance of local leaders. His tactics put strong emphasis on speed of movement and on the need to attack the enemy at his weakest point. The column’s ambush successes are small in number but among the best-remembered of the war. He admits, however, that his own and his column’s lack of experience with mines frequently weakened their offensives.
The column’s first successful ambush is at Tooreen on October 22, 1920, followed on November 28 by the dramatic ambushing of a patrol of auxiliaries at Kilmichael while traveling from their Macroom base. A column of thirty-six men, divided into three sections, kill sixteen auxiliaries, with one captured and later shot, suffering two fatalities of their own. Controversy has raged since over whether a false surrender by the British force caused the brutality of some of the deaths. Together with the Bloody Sunday killings of a week earlier in Dublin, Kilmichael has a profound effect on the British military and political establishment, with the declaration in December of martial law for much of Munster and the implementation of wide-ranging internment, together with the authorisation of official reprisals.
After a short period in hospital with a heart condition, in early 1921 Barry leads unsuccessful attacks on Kilbrittain, Innishannon, Drimoleague, and Bandon barracks. The seizure of Burgatia House, outside Rosscarbery, in early February, and the successful resistance made there to British troops, wins much publicity but has little military significance. He is a leading figure in the brutal final stage of the war in the first six months of 1921, which sees widespread shooting of suspected spies and destruction of loyalist property. By March 1921, his flying column, with 104 men, is easily the largest in Ireland, and an explosives expert, Capt. McCarthy, has joined them.
The protracted engagement between Barry’s column and encircling British forces at Crossbarry on March 19, 1921, comes at a time when large-scale sweeps are making life increasingly difficult for the IRA. It consists of a daring and courageous breakout. Crossbarry is the largest action of the war, and Barry is to regard it as even more important than Kilmichael. Soon afterwards, Rosscarbery barracks is successfully attacked by a Barry-led party, representing one of the few successful such initiatives in 1921. Isolated triumphs, however, cannot hide the fact that pressure is increasing on the column, and he becomes increasingly critical of inactive regions. He is later to say that all County Kerry does during the war is to shoot one decent police inspector at Listowel Racecourse and a colleague of his. He is strongly critical also of the lack of assistance from GHQ and of the divisionalisation policy. He visits Dublin in May, travels around with Michael Collins, and is present when two American officers demonstrate the Thompson submachine gun. He is more aware than most of his 1st Southern Division colleagues of the scarcity of arms and ammunition at the war’s end.
During the truce, Barry becomes liaison officer for Munster, riling the British by insisting on his military rank, and criticising the IRA liaison men in Dublin for being overly deferential. He joins the overwhelming majority of the Cork IRA in opposing the Anglo–Irish Treaty but plays a characteristically maverick role throughout the treaty split. His independent attitude is heightened by his dislike of Liam Lynch, the republican IRA’s Chief of Staff, and his continuing respect for Michael Collins. He shows impatience at the long-drawn-out peace initiatives. In March 1922, therefore, he advocates armed confrontation with pro-treaty units over the occupation of barracks in Limerick, and on June 18 he submits a resolution, which only narrowly fails, at the army convention, giving British troops seventy-two hours to leave Dublin.
At the beginning of the Irish Civil War, Barry is arrested entering the Four Courts disguised as a woman. He escapes from an internment camp at Gormanston in early September 1922. For the rest of the war his actions mirror its confused nature. In late October 1922, he leads successful raids on the small towns of Ballineen and Enniskean, and later on Inchigeelagh and Ballyvourney. In December his column takes Carrick-on-Suir, demonstrating the weakness of the Free State army, but his talk of advancing on the Curragh and of large-scale actions does not materialise. There is no evidence that he is acting in accordance with any coordinated plan. By February 1923, he realises that the Republican IRA cause is hopeless and he is involved with Fr. Tom Duggan in efforts to get 1st Southern Division to declare a ceasefire. He journeys to Dublin to put pressure on the intransigent Lynch in this connection, telling Lynch, “I did more fighting in one week than you did in your whole life.”
Barry avoids capture in roundups after the war, remaining on the run until 1924. Unlike many republicans, he does not turn to constitutionalism, remaining strongly militaristic. He is always an unreconstructed republican, though by no means a naive one. In 1924 he becomes attached to Cleeves Milk Co., based in Limerick and Clonmel, and from 1927 to retirement in 1965 is general superintendent with the Cork harbour commissioners. He strongly advocates preserving the independence of the IRA army executive during the republican split of 1925–27. He is instrumental in continuing the drilling of IRA members and is a strong supporter of armed opposition to the Blueshirts.
During the 1930s Barry is arrested at various times for possession of arms and seditious utterances. He promotes an attack against a Freemasons’ meeting in Cork in 1936 and gives the orders for the killing on March 4 of that year of Vice-AdmiralHenry Boyle Somerville. He is opposed to the use by Frank Ryan of IRA volunteers to support the republican cause in the Spanish Civil War and to the proposals of Seán Russell for a bombing campaign in England. To maintain the link with traditional republicanism, he is elected IRA chief of staff in 1937. His plan, however, for the seizure of Armagh city, as part of a direct northern offensive, quickly collapses due to a leak of information, and he soon resigns his position. He forcefully attacks the bombing of English cities in 1938, regarding attacks on innocent civilians as immoral and counterproductive. He enlists in the National Army on July 12, 1940, only to be demobilised a month later. In 1946, he stands as an independent candidate in a by-election in the Cork Borough constituency, finishing at the bottom of the poll. He is more comfortable the following year touring the United States on an anti-partition platform.
In 1949 his Guerilla Days in Ireland is published. It proves a best-seller and has frequently been reprinted. It is well written in a forceful and direct style, one memoir needing no assistance from a ghost writer. Age does not mellow him: lawyers and bank managers are threatened by him over matters relating to his own column, and in 1974 he publishes a fierce pamphlet, angry at perceived slights in the Irish War of Independence memoir of Liam Deasy. He does strive to achieve a public reconciliation with Collins’s memory by unveiling the memorial to Collins at Sam’s Cross in 1966. On the outbreak of the Northern Ireland crisis in the late 1960s, he takes a militant line, castigating the argument that the Six Counties can be brought into the Republic by peaceful means, and asking when had peaceful means existed there. At the memorial meeting in Carrowkennedy, County Mayo, in 1971, he claims that there is a perfect right at the opportune time to take the Six Counties by force. He remains opposed to IRA bombing of civilian targets.
Barry dies in Cork on July 2, 1980. He is buried in St. Finbarr’s Cemetery, Cork. Early in the truce of 1921 he marries Leslie Price, one of the most active of Cumann na mBan members during and after the rising. They have no children.
While Barry always remains an influential figure in republican circles, he will be remembered best as the pioneer of guerrilla warfare, the hero of Kilmichael and Crossbarry. His military flair, individualism, and ruthlessness are well suited to the 1919–21 conflict. After that, his strained relations with colleagues and his lack of flexibility reduce his importance. While his life after the revolutionary era appears anti-climactic, he retains much of his charisma. In later years, he is ever willing to remind politicians and historians how far Ireland has retreated from republican ideals. He is often prickly and autocratic yet could be generous to old colleagues of either side of the treaty split. He is arguably the most intelligent but also the most intolerant of the revolutionary leaders.

Humbert crosses the River Shannon at Ballintra Bridge on September 7, destroying it behind them, and continues to Drumshanbo where they spend the night – halfway between his landing-point and Dublin. News reaches him of the defeat of the Westmeath and Longford rebels at Wilson’s Hospital School at Multyfarmham and Granard from the trickle of rebels who have survived the slaughter and reached his camp. With Cornwallis’ huge force blocking the road to Dublin, facing constant harassment of his rearguard and the pending arrival of General Gerard Lake‘s command, Humbert decides to make a stand the next day at the townland of Ballinamuck on the Longford/Leitrim county border.
Humbert faces over 12,000 Irishmen and English forces. General Lake is close behind with 14,000 men, and Cornwallis is on his right at Carrick-on-Shannon with 15,000. The battle begins with a short artillery duel followed by a dragoon charge on exposed Irish rebels. There is a brief struggle when French lines are breached which only ceases when Humbert signals his intention to surrender and his officers order their men to lay down their muskets. The battle lasts little more than an hour.
While the French surrender is being taken, the 1,000 or so Irish allies of the French under Colonel Bartholomew Teeling, an Irish officer in the French army, hold onto their arms without signaling the intention to surrender or being offered terms. An attack by infantry followed by a dragoon charge breaks and scatters the Irish who are pursued into a bog where they are either bayoneted or drowned.
A total of 96 French officers and 746 men are taken prisoner. British losses are initially reported as 3 killed and 16 wounded or missing, but the number of killed alone is later reported as twelve. Approximately 500 French and Irish lay dead on the field. Two hundred Irish prisoners are taken in the mopping-up operations, almost all of whom are later hanged, including Matthew Tone, brother of Wolfe Tone. The prisoners are moved to the Carrick-on-Shannon Gaol. The French are given prisoner or war status however the Irish are not and some are hanged and buried in St. Johnstown, today known as Ballinalee, where most are executed in a field that is known locally as Bully’s Acre.
Humbert and his men are transported by canal to Dublin and exchanged for British prisoners of war. Government forces subsequently slowly spread out into the rebel-held “Irish Republic,” engaging in numerous skirmishes with rebel holdouts. These sweeps reach their climax on September 23 when Killala is captured by government forces. During these sweeps, suspected rebels are frequently summarily executed while many houses thought to be housing rebels are burned. French prisoners of war are swiftly repatriated, while United Irishmen rebels are executed. Numerous rebels take to the countryside and continue guerrilla operations, which take government forces some months to suppress. The defeat at Ballinamuck leaves a strong imprint on Irish social memory and features strongly in local folklore. Numerous oral traditions are later collected about the battle, principally in the 1930’s by historian Richard Hayes and the Irish Folklore Commission.
