Irish National Invincibles

The Irish National Invincibles, usually known as the Invincibles, were a splinter group of the Irish Republican Brotherhood. This group of assassins were active in Dublin between late 1881 and 1883, with an intent to kill the authorities in Dublin Castle.

After numerous attempts on his life, Chief Secretary for Ireland William Edward "Buckshot" Forster resigned in protest of the Kilmainham Treaty. The Invincibles settled on a plan to kill the Permanent Under Secretary Thomas Henry Burke at the Irish Office. The newly installed Chief Secretary for Ireland, Lord Frederick Cavendish, was walking with Burke on the day of his arrival in Ireland when the assassins struck, in Phoenix Park, Dublin, at 17:30 Saturday, 6 May 1882.

The first assassination in the park was committed by Joe Brady, who attacked Burke with a 12-inch knife, followed in short order by Tim Kelly, who knifed Cavendish. Both men used surgical knives. The British press expressed outrage and demanded that the "Phoenix Park Murderers" be brought to justice.

A large number of suspects were arrested. By playing off one suspect against another, Superintendent Mallon of "G" Division of the Dublin Metropolitan Police got several of them to reveal what they knew. The Invincibles' leader, James Carey, and Michael Kavanagh agreed to testify against the others. Joe Brady, Michael Fagan, Thomas Caffrey, Dan Curley and Tim Kelly were hanged by William Marwood in Kilmainham Gaol in Dublin between 14 May and 4 June 1883. Others were sentenced to long prison terms.
