This Saturday marks the centenary of Bloody Sunday, 21 November, 1920. Early on that morning, IRA members shot and killed 12 men believed to be British Army intelligence officers and two auxiliary policemen in locations throughout Dublin. British forces retaliated later that day by firing into a crowd attending a Gaelic football match in Croke Park, killing 14 civilians. A new display will be unveiled in Kilmainham Gaol Museum this Saturday focusing on the final act of that bloody day: the killing of Dick McKee, Peadar Clancy and Conor Clune in Dublin Castle whilst in British custody. The new display in Kilmainham Gaol Museum features artefacts associated with the three men, including several directly connected with the story of their deaths.
