My thanks to Doug Hurley for emailing me this and other poems of the late Aneurin Owen. 

 "CAMBRIAN : THE END" 

Their task was fraught with danger 
So resolutely met. 
With death a lurking stranger 
Their destiny was set. 

They fell on the way in quest for coal 
Which nature tried to keep. 
That mighty mine so powerful 
Its victims long asleep. 

Fearless, tough and friendly men. 
Their comradeship renowned. 
Right through that black iniquitous den, 
Their laughter did resound. 

Now mine itself entombed like they 
No more will maim or kill. 
The earth it's shroud, like them it lay 
So silent, cold and still. 

The valley such a finer place. 
Returned to former scene. 
If they but look with reverted face 
Would gaze on pastures green. 

 Written by Aneurin Owen of Clydach Vale.
