The Squad, originally nicknamed the Twelve Apostles, an Irish Republican Army (IRA) unit founded by Michael Collins to counter British intelligence efforts during the Irish War of Independence, is officially established on September 19, 1919, at 46 Rutland Square although by this time it has already been in operation for two months and has already carried out two killings.

On April 10, 1919, the First Dáil announces a policy of ostracism of Royal Irish Constabulary men. At the time Sinn Féin official policy is against acts of violence. Boycotting, persuasion, and mild intimidation succeed against many officers. However, others escalate their activities against republicans and in March 1920 Collins asks Dick McKee to select a small group to form an assassination unit.

When the squad is formed, it comes directly under the control of the Director of Intelligence or his deputy and under no other authority. The Squad is commanded by Mick McDonnell.

The original ‘Twelve Apostles’ are Mick McDonnell, Tom Keogh, Jimmy Slattery, Paddy Daly, Joe Leonard, Ben Barrett, Vincent Byrne, Sean Doyle, Paddy Griffin, Eddie Byrne, Mick Reilly, and Jimmy Conroy. After some time, the Squad is strengthened with the addition of Ben Byrne, Frank Bolster, Mick Keogh, Mick Kennedy, Bill Stapleton, and Sam Robinson. They are employed full-time and receive a weekly wage.

Sometimes the squad is strengthened as occasion demands by members of the Intelligence staff, the Active Service Unit, munition workers, and members of the Dublin Brigade.

On July 30, 1919, the first assassination authorised by Michael Collins is carried out when Detective Sergeant “the Dog” Smith is shot near Drumcondra, Dublin. The Squad continues targeting plainclothes police, members of the G Division of the Dublin Metropolitan Police, and occasionally, problematic civil servants. Organisationally it operates as a subsection of Collins’ Intelligence Headquarters. Two of the executions by The Squad are the killing on January 21, 1920, of RIC Inspector William Redmond of the DMP “G” Division and on March 2, 1920, of British double agent John Charles Byrnes.

One of the Apostles’ particular targets is the Cairo Gang, a deep-cover British intelligence group, so called since it has either been largely assembled from intelligence officers serving in Cairo or from the Dublin restaurant called The Cairo, which the gang frequents. Sir Henry Wilson brings in the Cairo Gang in mid-1920, explicitly to deal with Michael Collins and his organization. Given carte blanche in its operations by Wilson, the Cairo Gang adopts the strategy of assassinating members of Sinn Féin unconnected with the military struggle, assuming that this would cause the IRA to respond and bring its leaders into the open.

The most well-known operation executed by the Apostles occurs on Bloody Sunday, November 21, 1920, when British MI5 officers, linked to the Cairo Gang and significantly involved in spying, are shot at various locations in Dublin. Fourteen are killed and six are wounded. In addition to the Twelve Apostles, a larger number of IRA personnel are involved in this operation. The only IRA man captured during the operation is Frank Teeling. In response to the killings, the Black and Tans retaliate by shooting up a Gaelic football match between Dublin and Tipperary at Croke Park, killing fourteen civilians including one of the players, Michael Hogan, and wounding sixty-eight. The Hogan stand at Croke Park is named after him.

In May 1921, after the IRA’s Dublin Brigade takes heavy casualties during the burning of the Custom House, the Squad and the Brigade’s Active Service Unit are combined into the Dublin Guard, under the direction of Paddy Daly. Under the influence of Daly and Michael Collins, most of the Guard takes the Free State side and joins the Irish Army in the Irish Civil War of 1922-23. During this conflict some of them are attached to the Criminal Investigation Department and are accused of multiple assassinations of Anti-Treaty fighters.
