Came across an interesting reference from 1913 to a picket being placed by Larkin and ITGWU on Shelbourne Park when Shels were due to play Bohs.
Shelbourne were supported by south city dockers and Larkin claimed that some of the Bohs players were engaged in strike breaking. Bohs then were an amateur side and had students and I think Dublin based soldiers playing for them. Oliver St. John Gogarty played for Bohs for a while in the late 1890s.
I assume then that the 'scabs' involved were middle class 'volunteers' of the type which featured in British General Strike in 1926?
The picket itself attracted more than the match and there were attempts to stop Bohemians entering the ground. The DMP then baton charged the crowd and there were a number of serious injuries.
