Formation of An Garda Síochána in 1922

The Garda Síochána

Prior to the signing of the Anglo-Irish Treaty of December 1921, Ireland was policed by the Royal Irish Constabulary (RIC) and Dublin Metropolitan Police. Needless to say, due to their loyalty to the old British regime and their association with the Auxiliaries and Black and Tans, the RIC was totally unacceptable to the vast majority of Irish people it was, therefore, a necessity to form a new policing agency with which to replace it.

The Metropolitan Police in the meantime was to carry on as they were. The inaugural meeting of a committee responsible for the foundation of a new police force took place on January 1922 at the Gresham Hotel in Dublin. The chairman was Michael Staines a member of the supreme council of the Irish Republican Brotherhood and a veteran of the Easter Rising of 1916 in which he served as Quartermaster General in the GPO. He was also a member of Dáil Éireann.

The creation of the Civic Guards

By 21st February 1922, the committee issued instructions to the Volunteer Brigade commanders to begin recruiting suitable candidates for the new police force which was to be armed and known as the “Civic Guards”. These recruits were to be single men, at least 5’9” tall and able to pass examinations in arithmetic, reading, and spelling. The first Commissioner of the new force was Michael Staines.

Initially, the first recruits were trained at R.D.S. Ballsbridge but were soon to be relocated to Kildare Military Barracks. Here, on 15th May 1922, whilst Michael Staines was delivering his morning address, over 1,000 guards broke ranks and seized the armory. Staines and his senior officers had to flee the scene.

It took Michael Collins, as chairman of the Provisional Government seven weeks to bring about an end to the mutiny. It was said to have been caused by anti-treaty sympathizers amongst the recruits objecting to the use of ex-RIC members as instructors in the force. Staines handed in his resignation which was accepted in August. He was replaced by General Eoin O’Duffy.

It was not until the middle of September that members of the Garda Síochana were diffused to various locations throughout the country although Dublin Castle and Ship Street barracks had been occupied by August when the force was still known as the Civic Guards. It was at Ship Street that the force suffered its first fatality when 19 years old Guard Charles Eastwood was accidentally killed by a comrade. This accident led to the disarming of the uniformed members of the force and considering that the country was in the throes of a vicious civil war it was a very bold step and one which demonstrated the bravery of each individual guard.

In October 1922 the first fatality due to Civil War activities occurred when Garda Henry Phelan was shot dead in mistake for his brother who had been a member of the RIC. By December that year, the British had evacuated Phoenix Park Depot and nearby Marlborough barracks and The Garda Síochána moved in. Marlborough was renamed as McKee Barracks.

Criminal Investigation Department

The Criminal Investigation Department was formed on 22 August 1922, the same day that Michael Collins fell to a sniper’s bullet. The C.I.D was to be “distinct from existing police forces with separate headquarters under the direct control of the Minister for Home Affairs”. This department was formed from members of the Irish Republican Police and members of the National Army. It consisted of over 100 heavily armed men and three women who posed as typists but whose real job was to ferret out women engaged in anti-state activities.

The CID headquarters was at Oriel House on Westland Row in Dublin. The Irregulars were to target the CID several times over the next few months killing two men and wounding others.

By October 1923 the Free State was stable enough for the CID to be disbanded and its personnel transferred to the Dublin Metropolitan Police.
In 1925 the DMP was itself amalgamated with the Garda Síochána and in 1928 the first Garda Síochána Code was published and strictly enforced by formal and informal investigations by senior officers.
