I`m interested where your info comes from,
As being a 3rd generation Collier,this History,part of ones Heritage has been handed down through the family,
But as an open minded person,after seeing your first reply,i googled up Tonypandy Riots,and clicked on the 2nd down,1910 Cambrian Combine strike,
And this corresponded to what my family have handed down
13 Miners were arrested in the riots,and while thier trial was going on,10,000 marched in support of thier fellow workers,although the streets were full of Police and Soldiers.
The town and area had been turned into a Military camp.
23rd November 1910,Miners were forced up on to the mountain at Penygraig at the point of Bayonets.
They were there for sure.
