Patrick O'Donnell (Invincible)
Patrick O'Donnell (1835 – 17 December 1883) was an Irish republican executed for the murder of James Carey, whose testimony for the prosecution led to the executions of five men adjudged responsible for the Phoenix Park Murders.
The Phoenix Park murders and Carey's death
On 6 May 1882, the most senior Irish civil servant, the Permanent Undersecretary, Thomas Henry Burke and the newly appointed Chief Secretary for Ireland, Lord Frederick Cavendish – who was also the nephew of Prime Minister William Ewart Gladstone – were murdered as they walked through Phoenix Park in Dublin by a man who stabbed them both with hospital scalpels.
The Irish National Invincibles
A number of secret organisations were plotting acts of terror from parts of the US and the UK. Among these was the Irish Republican Brotherhood, founded in the United States on 17 March (St. Patrick's Day), 1858, and widely known as the Fenians. The group perpetrated a number of attacks throughout the UK, targeting prisons and arsenals. Their expressed goal was full independence for Ireland and the creation of an Irish Republic. A splinter group, the Invincibles, plotted to assassinate Thomas Burke, a Catholic helping to administer British rule from Dublin Castle. The new Chief Secretary of Ireland, Lord Cavendish, was not an intended victim but happened to be out walking with Burke at the time of the attack.
