Kevin Gerard Barry
Executed Irish Republican Army volunteer
Died: 1 November 1920 aged 18 Mountjoy Jail, Dublin, Ireland
Cause of death: Execution by hanging
Kevin Gerard Barry (20 January 1902 – 1 November 1920) was an Irish Republican Army (IRA) soldier and medical student who was executed by the British Government during the Irish War of Independence. He was sentenced to death for his part in an attack upon a British Army supply lorry which resulted in the deaths of three British soldiers.
His execution inflamed nationalist public opinion in Ireland, largely because of his age. The timing of the execution, only seven days after the death by hunger strike of Terence MacSwiney, the republican Lord Mayor of Cork, brought public opinion to a fever-pitch. His pending death sentence attracted international attention, and attempts were made by U.S. and Vatican officials to secure a reprieve. His execution and MacSwiney's death precipitated an escalation in violence as the Irish War of Independence entered its bloodiest phase, and Barry became an Irish republican martyr.
