St. Stephen's Green, Dublin

Commandant Michael Mallin and his second in command, Constance Markievicz, were assigned to St. Stephen’s Green, a rectangular park, approximately twenty acres in size located a mile south of the General Post Office and close to Jacob's biscuit factory.

Mallin proceeded to fortify his position, posting men in some of the houses overlooking St. Stephen's Green and setting men to work digging trenches to cover the entrances. It soon transpired that St. Stephen’s Green was a vulnerable position, as it was overlooked by the Shelbourne Hotel and some other tall buildings that had not been occupied by Mallin’s forces. The British directed machine gun fire from the Shelbourne Hotel onto the Green late on Easter Monday, as a result of which Mallin abandoned most of it on Tuesday.

The majority of the Irish Citizen Army forces then garrisoned the Royal College of Surgeons immediately to the west of St. Stephen's Green. As Brigadier-General Lowe concentrated on the G.P.O. and the Four Courts, the College of Surgeons garrison wasinvolved in little action until the order for surrender came the following Sunday, 30 April 1916.
