Liam Deasy

Deasy was born in Kilmacsimon, Bandon in County Cork on 6 May 1896, and educated in the local school at Ballinadee.[1] He was the third son of William and Mary Deasy.[1]

In the War of Independence (1919–21, he was the Adjutant of the 3rd Cork Brigade (West Cork).[2]

He served under Tom Barry in one of the unit's best known action, the Crossbarry Ambush in March 1921. His younger brother, Pat, died in action at the Kilmichael Ambush in November 1920, an engagement which Liam Deasy himself was not present at.

He also took part in the Tooreen ambush.

He opposed the Anglo-Irish Treaty which ended the war. In the months that followed he, along with others like Éamon de Valera and Liam Lynch, tried to persuade Michael Collins to renegotiate aspects of the treaty, especially to remove an oath to the British king from the constitution of the new Irish Free State. When fighting broke out in Dublin in June 1922, between pro and anti-Treaty forces, Deasy sided with the Anti-Treaty IRA in the ensuing Irish Civil War. However, he was reluctant to fight his former comrades and voiced the opinion that the fighting should have ended with the Free State seizure of the Four Courts.

In late July, he commanded 1,500 anti-treaty fighters who held a line around Kilmallock south of Limerick city against about 2,000 Free State troops under Eoin O'Duffy. Deasy's men were the most experienced IRA fighters of the 1919-21 war and held their position until 8 August, when they were outflanked by seaborne landings on the southern coast. Deasy's men then dispersed. He went on the run in the south-east of the country.

In August 1922, he was in command of a band of republican guerrillas in west Cork, when they heard that Free State leader Michael Collins was in the area. Deasy had his men prepare an ambush for Collins' convoy at Béal na Bláth, should it return by the same route it had taken earlier.

Deasy and most of his men did not take part in the ambush as they had retired to a nearby pub, assuming that they had missed Collins. However, Collins arrived as the last of Deasy's men were clearing the mine and barricade that had been erected on the road at Béal na Bláth. Collins was killed in the ensuing firefight. Deasy later wrote in his memoirs that he profoundly regretted the death of his former commander. It is not clear that he gave orders otherwise to take on prisoners as the main intention of the ambush.

Deasy took no further part in politics following the end of the civil war. In 1924, he set up a business making weatherproof textiles.[1]On 24 November 1927, Deasy married Margaret Mary O'Donoghue; the two would have 3 daughters together.[1]

During The Emergency, Deasy served in the Irish Army from 1940 to 1945, reaching the rank of commandant.[1] Deasy would later write two memoirs about his experiences during the revolutionary period: Toward Ireland Free and Brother against Brother, the latter being published after his death.[1]

He died at St. Anne's Hospital in Dublin on 20 August 1974.[1]
