On Easter Monday April 24, 1916, Irish Volunteers, under the command of Eamonn Ceannt occupied a number of strategic positions in Dublin. One of these buildings was the South Dublin Union. This building was intended as a counterpart south of the river Liffey to the General Post Office on the north of the river. By 2:00 p.m on Easter Monday, that small force of Irish Volunteers was under attack from a large force of the British army. This was to be the beginning of an intense, unremitting guerilla battle that would last until the 30th of April 1916.
