Liam Lynch, Chief of Staff of the Irish Republican Army (IRA), is mortally wounded by Irish Free State troops in County Tipperary on April 10, 1923, as they try to avoid capture. He is transported to St. Joseph’s Hospital in Clonmel but dies there that night.

Lynch is born on November 9, 1893, in Barnagurraha, Anglesboro, County Limerick, the fifth child among six sons and a daughter of Jeremiah Lynch, farmer, and Mary Lynch (neé Kelly). The family is politically active. His father’s brother, John, had taken part in the Fenian Rising of 1867 and his mother had been joint secretary of the Ballylanders branch of the Ladies’ Land League.

Lynch attends Anglesboro national school (1898–1909). In 1910 he moves to Mitchelstown, County Cork, to take up a three-year apprenticeship in the hardware store of P. O’Neill on Baldwin Street. He remains there until the autumn of 1915. While in Mitchelstown he is a member of the Gaelic League and the Ancient Order of Hibernians. He also joins the Irish Volunteers. In 1914, when that organisation splits, he does not immediately join the militant rump. He then moves to Fermoy, County Cork, where he works in the store of Messrs J. Barry & Sons Ltd. His move coincides with a period of inactivity as neither Volunteer faction is very active nor is he known. Consequently, he does not take part in the 1916 Easter Rising, but it is a turning point for him. On May 2, 1916, he watches as the Kent family are led through Fermoy, having been captured by British soldiers. Richard Kent dies from a wound sustained that day and Thomas Kent is executed a week later. Lynch becomes a committed Volunteer at this point.

Once committed, Lynch’s enthusiasm and aptitude ensures that he quickly attains positions of responsibility. From early 1917 he is first lieutenant in the small Fermoy company. In September 1917, the Irish Volunteers in east Cork are reorganised. Nine local companies are formed into the Fermoy battalion and he is elected adjutant. In April 1918, at the height of the conscription crisis, he briefly quits his job to concentrate on organising the Volunteers. In May he is lucky to escape arrest during the sweep that accompanies the “German plot.” When the immediate danger ends he returns to Barry & Sons.

In January 1919, at the beginning of the Irish War of Independence, the Volunteer organisation in Cork undergoes a major restructuring. Three brigades are established, and Lynch becomes brigade commandant of Cork No. 2. In April he visits Irish Republican Army GHQ in Dublin to discuss plans and to seek arms. It is a frustrating experience as the GHQ has few guns and are cautious about action. Throughout the summer of 1919 he presses GHQ to authorise attacks on British targets as a method of acquiring arms and to prevent boredom and stagnation setting in among his men. Finally, GHQ sanctions attacks if the primary aim is the capture of arms. In response, on September 7, 1919, twenty-five men from the Fermoy company, led by Lynch, ambush fourteen British soldiers on their way to service in the Wesleyan church in Fermoy. Fifteen rifles are captured, one soldier killed, and three wounded. Lynch is shot in the shoulder, probably by one of his own men. As a result, he has to leave his job and hides out in Waterford for a time. A series of arrests follow, among those is Lynch’s close friend, Michael Fitzgerald, who dies on hunger strike in Cork County Gaol in 1920.

Lynch spends the early months of 1920 at GHQ in Dublin. During this time, he is offered the position of deputy chief of staff, but turns it down, preferring to return to Cork. Although not an articulate speaker, he impresses those he meets. His organisational talents, attention to detail, ability to inspire, and intolerance for those who waste meetings endlessly discussing side issues, are noted. He has a low tolerance for politicians and at all times considers the military wing of the movement to be of primary importance. He is engaged to Bridie Keyes, but marriage is postponed pending a final settlement of hostilities.

On June 26, 1920, Lynch, Seán Moylan, and two colleagues capture Major-General Cuthbert Lucas while he is fishing on the Munster Blackwater. He gives a false name when he is arrested on August 12, 1920, at City Hall, Cork, with Terence MacSwiney, Lord Mayor of Cork, and ten others. All but MacSwiney are released four days later. He then sets about organising a flying column within the brigade. Ernie O’Malley arrives from headquarters to train the men. This column achieves a major coup on September 28, 1920, when they briefly capture the British Army barracks at Mallow, leaving with a large booty of rifles, ammunition, and two machine guns. The British respond to this increase in activity and the war settles into a pattern of ambush and counter-ambush. The Mallow battalion suffers severe losses in February 1921 and Lynch himself narrowly escapes when four are killed during an encounter at Nadd in March 1921.

In early 1921 Lynch seeks to encourage greater cooperation between the various brigades in the south. Senior brigade officers meet on three occasions to discuss cooperation and a plan to import arms from Italy. The importation project fails, but the First Southern Division is formed on April 26, 1921, bringing eight brigades from Cork, Kerry, Waterford, and west Limerick together. He is elected divisional commandant, making him the most powerful officer outside GHQ. His influence is further increased by his appointment as Southern Divisional Centre and Supreme Council member of the clandestine Irish Republican Brotherhood (IRB) in March 1921.

Lynch is wary when the truce is called in July 1921. He works hard to maintain order in his division and to achieve a state of readiness in case the negotiations fail. For him the Anglo-Irish Treaty is a failure. When the Supreme Council of the IRB meets on December 10, 1921, he is the only voice against the agreement. He is among the officers who insist that an army convention should be called to discuss the treaty, effectively asserting that the army no longer accepts a position subordinate to the Dáil. The army, he believes, is the army of the Republic, and no civilian body can order it to abandon the Republic. The provisional government tries to ban this convention, but it goes ahead on March 26, 1922, and elects an army executive. Lynch is elected Chief of Staff. Between March and June, he works hard to prevent a civil war. He believes unity can be maintained, even under the Treaty, if a republican constitution can be enacted. He also cooperates with Michael Collins in promoting Irish Republican Army (IRA) activity in Ulster. In his adherence to the idea of a republic, the practicalities of politics have little impact on his consciousness and he is dismissive of the popular support for the Treaty. He is horrified at the thought of civil war but fails to see that his position is leading almost inexorably in that direction. Distrusted as too moderate by Liam Mellows and Rory O’Connor, he is locked out of the Four Courts for a time.

When the Four Courts are attacked, Lynch immediately leaves his headquarters at the Clarence Hotel to travel south. He is briefly detained, before reaching Kingsbridge Station, and has a meeting with Eoin O’Duffy. He is disgusted when Free State figures later claim that he was released, having promised not to take arms against the government. The most plausible explanation of the incident appears to be that O’Duffy interpreted Lynch’s comments, merely indicating disappointment that a war had started, as constituting a statement of intent not to involve himself.

Lynch’s initial actions seem designed to avoid full-scale conflict. He does not order an attack on Dublin, nor does he attempt to seize Limerick. He chooses a containment strategy, seeking to hold a line from Limerick to Waterford for the republican forces. This fails, as the government sends troops in from the rear by sea. The republicans have no urban base when Lynch abandons Fermoy on August 11, 1922. He continues to meet individuals who seek a way to end the war, but intransigence has set in and he insists that armed struggle will only end with a republic or absolute defeat. As early as August many republicans believe the war is lost and urge a reassessment of tactics, but Lynch rejects all such calls. Operating from secret headquarters in Santry, he orders the shooting of pro-Treaty politicians in retaliation for the execution of republican prisoners.

Under war conditions it is impossible for the army executive to meet regularly, and this leaves Lynch in almost complete control. As the pro-surrender lobby grows within the republican forces, he delays a meeting of the executive, claiming with some justification that it is too dangerous. He leaves Santry and attends a meeting of the Southern Division Council in the last days of February 1923. Sixteen of the eighteen officers there tell him that the military position is hopeless. This forces the calling of an executive meeting on March 6, 1923. No agreement is reached. He strongly favours fighting on, but a motion from Tom Barry, calling for an immediate end to hostilities, is barely rejected. Another meeting is arranged for April 10. On that morning a group, including Lynch and Frank Aiken, suddenly find themselves in danger of capture in a farmhouse on the slopes of the Knockmealdown Mountains in County Tipperary. They flee and are pursued. During the chase Lynch is shot in the abdomen. It seems clear that he is shot by the pursuing Free State soldiers, although Irish historian Meda Ryan has considered the theory that he may have been shot by one of his own in order to remove the major stumbling block to surrender. His colleagues are forced to abandon him, and he is captured. Initially the Free State troops believe they have caught Éamon de Valera. He is taken first to a public house in Newcastle, County Tipperary, and then to St. Joseph’s Hospital in Clonmel, but dies from his wound at 8:45 p.m. that evening. His last request is to be buried beside Michael Fitzgerald in Kilcrumper Cemetery, Fermoy, County Cork. On hearing of Lynch’s death, Ernie O’Malley writes, “You who were a living force are now a battle cry.” O’Malley is wrong, however, as the peace faction within republicanism is strengthened by his death and Aiken orders the suspension of activities on April 27.

In 1935, a massive memorial, consisting of a 60-foot-tall round tower, guarded by four bronze Irish Wolfhounds, is erected at Goatenbridge, County Tipperary, near the site of his capture. It is unveiled on April 7, 1935. Separate annual commemorations are held at Goatenbridge and Kilcrumper. Three biographies have been written and the Liam Lynch memorial pipe band is based in his native Anglesboro. The Lynch family possess a substantial collection of private correspondence.
