Thomas Hales, Irish Republican Army (IRA) volunteer and Fianna Fáil politician, is born in Knocknacurra House, Ballinadee, near Bandon, County Cork, on March 5, 1892.

Hales is born on a family farm owned by his father, Robert Hales, an activist in the Irish Land War and a reputed member of the Irish Republican Brotherhood (IRB) and his wife, Margaret (née Fitzgerald). He is the sixth of nine children (five sons and four daughters). He is educated at Ballinadee national school and Warner’s Lane school, Bandon. After leaving school he works at Harte’s timber yard, Bandon.

Hales joins and is involved with the Irish Volunteers movement from its inception in November 1913. Elected a delegate at the Volunteer national convention in the Abbey Theatre in 1915, he is among the majority who vote for the election of the national executive.

Hales is a part of a group of volunteers who are mobilised and plan to rise up in Cork during the 1916 Easter Rising. He sends a number of dispatches to Cork requesting further instructions. However, they receive last minute orders to stand down and there is no uprising in Cork to match that in Dublin. The Volunteers give up their arms and are later arrested.

By May 1916, Hales and his brothers, Seán, Bob, and William, are fighting with the IRA in west Cork during the Irish War of Independence. Terence MacSwiney is arrested in Hales’ home on May 3, 1916, and Hales himself escapes and goes on the run. He states that he was listed as “wanted” in the Hue and Cry police gazette.

In 1918, Hales takes part in a raid on a British gunboat and holds 25 armed Royal Irish Constabulary (RIC) members prisoner at Snugmore Castle. He takes part in a decoy in assisting his elder brother, Seán, to escape after his arrest in connection with the German Plot. He is elected Battalion Commandant of the 1st (Bandon) Battalion (1917–19), and Brigade Commandant of Cork 3rd Brigade, IRA, in January 1919.

In December 1919, Hales takes part in an ambush against the RIC at Kilbrittain and Bandon and is involved in the manufacture of gunpowder for IRA munitions. By this point he is the commander of the Third Cork Brigade of the IRA. In July 1920, he along with Harte is arrested by soldiers from the Essex Regiment.

The pair are taken to a nearby military barracks, where they are severely beaten while being interrogated by officers of the regiment. Hales has his fingernails pulled out, an event that later inspires a scene in the film The Wind That Shakes the Barley. However, neither Hales nor Harte give up any information and are eventually sent to a military hospital to recuperate. Hales is tried and is eventually sentenced to two years’ penal servitude, which he serves in Pentonville and Dartmoor prisons in England. He is commander of the Irish prisoners at Pentonville, but is released following a general amnesty after the Anglo-Irish Treaty in December 1921. According to Tom Barry, Harte suffers brain damage and goes insane before dying in Broadmoor Hospital.

A fifth Hales brother, Donal, settles in Genoa from 1913, and is appointed Irish Consular and Commercial Agent for Italy in February 1919. In this capacity he plays a leading propaganda role. Several letters from Michael Collins to Donal Hales still exist which are used by Hales to promote international awareness of the Irish conflict in Italian publications. Donal oversees a failed attempt to import a substantial number of Austrian weapons and ammunition captured from World War I, from Genoa in the spring of 1921, through the person of Gabriele D’Annunzio.

During the Irish Civil War, Tom and Seán Hales fight on opposite sides, with Hales fighting against the Anglo-Irish Treaty with the Anti-Treaty IRA while Seán joins the newly formed National Army of the Irish Free State. While the bothers end up on opposite sides of the war, they never openly criticise one another for their rival political stances.

Hales is elected to the anti-Treaty IRA executive in March 1922, but resigns in June over a proposal to prevent the Free State’s first general election in June 1922. He resumes his old rank during the Irish Civil War as commander of Cork 3 Brigade.

During the Irish Civil War in July 1922, Hales takes part in the raid and capture of Skibbereen Barracks and Ballineen by anti-Treaty forces. He is also involved in a skirmish with Free State troops at Newcestown. He is arrested in November 1922 and imprisoned first in Cork and then at the Curragh. He is released in December 1923, having taken part in a hunger strike for fourteen days. He mentions in his application for a military pension that he was a member of the Supreme Council of the IRB at this time.

In December 1922, Hales’s brother Seán is assassinated by the anti-Treaty IRA in Dublin, in reprisal for the Free State government’s execution of IRA prisoners. Hales later applies to the Irish government for a service pension under the Military Service Pensions Act, 1934 and is awarded nine years’ service in 1935 at Grade B for his service with the Irish Volunteers and the IRA between April 1, 1917, and September 30, 1923.

Hales is elected to Dáil Éireann as a Fianna Fáil Teachta Dála (TD) for the Cork West constituency at the 1933 Irish general election. He resigns from Fianna Fáil in June 1936 stating he cannot support their policy on interning IRA members. He fails to retain his seat as an independent candidate at the 1937 Irish general election. He also unsuccessfully contests the 1944 Irish general election as an independent candidate and the 1948 Irish general election as a candidate for Clann na Poblachta, receiving 2,287 votes (7.93%).

Hales makes his living as farmer. A member of the Mallow area board of the beet growers’ association from 1934 to 1942, he is also connected with other farming organisations. He marries Ann Lehane from Tirelton, Macroom, on April 30, 1927. They have five children, Seán, Robert, Thomas, Eileen, and Margaret.

Hales dies on April 29, 1966, at St. Finbarr’s Hospital, Cork, and is buried at St. Patrick’s Cemetery, Bandon.
