Just a bit more info, I've just taken part, as a member of the community choir, in the reenactment of the Mold Riots of 1869.
A neighbouring pit to the Tryddyn Vale Colliery, Leeswood Green Colliery had a new manager brought in from County Durham by the (English) mine owner along with a handful of English colliers from Lancashire. One of his first acts was to forbid the existing men from speaking their native tongue, Welsh, in the mine. Next he cut their pay which sparked much unrest such that they raided his house, put him on a train back to England and emptied his house of his goods.
The Police arrested the ringleaders and they were tried in Mold and given heavy sentences. As they were being escorted to the train, the riot broke out and the Chester Militia were mobilised. It ended up with shots being fired and 4 people were killed - colliers wives...
It was a dark day in our town's history and the reenactment play has really gripped the town with it being a sell out for 6 / 7 weeks beforehand.
The message at the end was as true back in 1869 as it is today - Wales is a welcoming nation but respect our language and traditions, learn from us and together we can have a bright future...
