Grangegorman Lives: Patrick O'Daly

05 April 2024

The next addition to our Grangegorman Lives series is Patrick O'Daly, soldier and counter-intelligence officer.

Patrick O’Daly (1888 - 1957) was a soldier and counter-intelligence officer who helped to further the republican cause in Ireland. Originally trained as a carpenter, O’Daly quickly became involved in the Irish republican political movement, swearing into the Irish Republican Brotherhood at 19 years old. Following his participation in the Easter Rising, O’Daly was sent to the Richmond hospital for treatment and promptly arrested in his bed. He was then extradited to a Welsh prison, before being released under the terms of the general amnesty agreement in December of the same year. O’Daly would continue his participation in the Irish Republican Brotherhood, commanding the Guard’s 1st Company through Dublin to accept the hand-over of Beggars Bush barracks from British troops on February 1st, 1922. O’Daly resigned his commission with the Irish Republican Brotherhood in 1924, returning to life as a civilian.
