As I understand it strikebreakers come from Cornwall Wales and Ireland. The last group to be forgiven were the Cornish miners as they knew exactly what they were doing.The Irish strikebreakers were relatively quickly forgiven as they had little if any knowledge of the reasons for the need for miners. Indeed 150 years later Tyneside now has a thriving Irish community adding to the music and song of the North East.

Perhaps fuller details will be forthcoming.
