Ulster Special Constabulary

The Ulster Special Constabulary (USC; commonly called the "B-Specials" or "B Men") was a quasi-military reserve special constable police force in what would later become Northern Ireland. It was set up in October 1920, shortly before the partition of Ireland. The USC was an armed corps, organised partially on military lines and called out in times of emergency, such as war or insurgency. It performed this role most notably in the early 1920s during the Irish War of Independence and the 1956–1962 IRA Border Campaign.

During its existence, 95 USC members were killed in the line of duty. Most of these (72) were killed in conflict with the IRA in 1921 and 1922. Another 8 died during the Second World War, in air raids or IRA attacks. Of the remainder, most died in accidents but two former officers were killed during the Troubles in the 1980s.

The force was almost exclusively Ulster Protestant and as a result was viewed with great mistrust by Catholics. It carried out several revenge killings and reprisals against Catholic civilians in the 1920–22 conflict. Unionists generally supported the USC as contributing to the defence of Northern Ireland from subversion and outside aggression.

The Special Constabulary was disbanded in May 1970, after the Hunt Report, which advised re-shaping Northern Ireland's security forces to attract more Catholic recruits and demilitarising the police. Its functions and membership were largely taken over by the Ulster Defence Regiment and the Royal Ulster Constabulary.

The Ulster Special Constabulary was formed against the background of conflict over Irish independence and the partition of Ireland.

The 1919–21 Irish War of Independence, saw the Irish Republican Army (IRA) launch a guerrilla campaign in pursuit of Irish independence. Unionists in Ireland's northeast were vehemently against this campaign and against Irish independence. However, once it became apparent that the British government was committed to implementing Dominion Status for all of Ireland outside Ulster in response to Sinn Féin's demands, which were far more radical than those of the defunct Irish Parliamentary Party, Unionists in most of the province of Ulster directed their energies into the partition of Ireland by the creation of Northern Ireland as an autonomous region in the United Kingdom. The new region would consist of two thirds of Ulster, the six counties that Unionists could control. The other three counties (Donegal, Monaghan, and Cavan) had disproportionately Catholic and nationalist majorities and would become part of the Irish Free State. Partition was enacted by the British Parliament in the Government of Ireland Act 1920.

Two main factors were behind the formation of the Ulster Special Constabulary. One was the desire of Unionists, led by Sir James Craig (then a junior minister in the British Government, and later the Prime Minister of Northern Ireland), that the apparatus of government and security should be placed in their hands long before Northern Ireland was formally established.

A second reason was that violence in the north was increasing after the summer of 1920. The IRA began extending attacks to the Royal Irish Constabulary (RIC), RIC barracks, and revenue offices in Northern Ireland. There had been serious rioting between Catholics and Protestants in Derry in May and June and in Belfast in July, which had left up to 40 people dead.
