April 27th 1916, Day 4 Of The Easter Rising
From early morning on Day 4 rebel positions like the South Dublin Union and the Marrowbone Lane Distillery, and the Four Courts come under heavy British attack.
Meanwhile the British continue to pound Sackville Street with artillery fire as they attempt to destroy the rebel HQ in the GPO, by evening the British take Capel Street and James Connolly is wounded on Middle Abbey Street and taken back to the GPO for treatment.
Cathal Brugha was wounded badly at the South Dublin Union garrison which was under the leadership of Éamonn Ceannt. The fighting in the hospital had come down to close-quarter combat between rebels and soldiers but was not taken as British soldiers are needed in the city centre.
British troops have now taken many of the main streets around Dublin it was now impossible for the insurgents to move arms, messages or people to or from the GPO headquarters to other rebel-held positions around the city.
By around 10 pm British soldiers also began invading the north inner city where the Volunteers under command of Tom Clarke’s brother-in-law Ned Daly had offered fierce resistance all week. The military effort involved efforts to occupy houses, leading to the shooting and killing of several uninvolved civilians in the North King Street area.
By the end of day four, with the continued bombardment from the British, rebels on O’Connell Bridge, south of the GPO on Sackville St, and those along Henry St., which runs just to the north of the building, begin to retreat to the rebel headquarters.
But things are becoming desperate in the GPO, because of the constant bombardment there are constant fires breaking out. Between the buildings around the GPO, the Irish Times Warehouse, and the Oil Works, Dublin glowed red with fire by the time night fell.
