This is a letter from James Connolly (1868-1916), socialist and revolutionary, to Éamonn Ceannt (1881-1916), Irish-Irelander and revolutionary. This letter was written at 7.30am to summon Ceannt to a meeting of the leaders of the Rising on Easter Sunday morning 1916. Connolly writes that both he and Thomas MacDonagh (1878-1916). another of the leaders of the Rising, felt it was necessary to hold a meeting. It was at that meeting that, owing to a number of set-backs, it was decided to postpone the Rising until the following day. Connolly was an active trade union and socialist organiser and commandant of the Irish Citizen Army. In 1916 he joined the military committee (later Military Council) of the Irish Republican Brotherhood and became intimately involved in the planning and execution of the Easter Rising. He was a signatory of the Proclamation of the Irish Republic and commander in chief of the rebel forces in Dublin during the Rising. He was executed on 12 May. Ceannt was an active cultural nationalist and separatist and was a member of the Gaelic League, the Irish Volunteers (where he was director of communications and commandant of the 4th Dublin battalion) and the Irish Republican Brotherhood. Ceannt was a signatory of the Proclamation of the Irish Republic and during the Easter Rising Ceannt commanded the garrison of rebels in the South Dublin Union. He was executed on 8 May 1916.
