After the events of Easter Sunday, 1916, the nationalist leaders that supported an independent Irish Republic were all quickly court-martialed, then brutally shot (executed) at Dublin's Kilmainham Gaol (prison) by the British.
Within that prison (marked by a cross) stood the Irish heros, Eamonn Ceannt, Tom Clarke, Cornelius Colbert, James Connolly, Edward Daly, Sean Mac Diarmada, Sean J. Heuston, Michael Mallin, Major John McBride, Thomas McDonough, Michael O'Hanrahan, Patrick Pearse, William Pearse and Joseph Plunkett. All were marched (blindfolded) into this prison courtyard, then executed at point-blank range by British solders. James Connolly was so badly injured in previous fighting that he could not stand, so he was placed in a chair, and then shot. Thomas Kent was later shot in Cork, Ireland, and Roger Casemen was hanged in London, England.
Despite its military failure - mainly because of the overpowering force of British troops in Dublin - this event, this 'Easter Rising" is rightfully judged as the most significant inspiration in the eventual creation of the Irish Republic. If you ever travel to Dublin, Ireland, don't miss touring Kilmainham Gaol. And when you stand in the central courtyard and see this cross (there are two) you can't help but feel proud of the men that died here, and it's a moment that will stay in your mind for a very long time.
