Coniston massacre
Brooks was killed on or about 7 August 1928, and his body was partly buried in a rabbit hole. No eyewitnesses to the actual murder were ever identified, and there are conflicting accounts of the discovery of the body and subsequent events.
Rory O'Connor (Irish republican)
On 8 December 1922, along with three other republicans Liam Mellows, Richard Barrett and Joe McKelvey captured with the fall of the Four Courts, Rory O'Connor was executed by firing squad in reprisal for the anti-treaty IRA's killing of Free State TD Sean Hales. The execution order was signed by Kevin O'Higgins. O'Connor had been best man at his wedding on 27 October 1921. The killing remains as a symbol of the bitterness and division of the IRA's Civil War. O'Connor, one of 77 republicans executed by the Cumann na nGaedheal government of the Irish Free State, is seen as a martyr by the Republican movement in Ireland.
