The most well-known operation executed by the Apostles occurred on what became known as Bloody Sunday, November 21, 1920, when British MI5 officers, linked to the Cairo Gang and significantly involved in spying, were shot at various locations in Dublin (14 were killed, six were wounded). In addition to the "Twelve Apostles", a larger number of IRA personnel were involved in this operation. The only IRA man captured during the operation was Frank Teeling. In response to the killings, the Black and Tans retaliated by shooting up a Gaelic football match between Dublin and Tipperary at Croke Park, the proceeds from which were for the Irish Republican Prisoners Fund, killing fourteen civilians including one of the players, Michael Hogan, and wounding sixty-eight. The Hogan stand at Croke Park is named after him.
