My thanks to Joe Mooney of the East Wall History Group for sending on this excellent little 1916 story, which he notes comes from a magazine that was contained “Within material donated to the East Wall History Group by the family of Irish Volunteer Richard Roe (Jacobs Garrison 1916)”
Two soldiers were discovered hiding out in the runs of the Coliseum Theatre in Henry Street on 3 May 1916, confused as the whether or not the rebellion was exactly still underway. By 3 May the executions of the rebellions leadership figures were already underway.
The following account and images were published in a contemporary magazine.
