Have these people read - War Underground by Barrie or Hill 62 ?
There is one major difference between mining in say a coal mie or any other mine, and those dug on the western front, in that in addition to all the dangers you know that someone is tunnelling towards you and all they want to do is kill you. I suppose there has to be something in the knowledge that the very next step might be you last !
Inspite of any report, I would agree that the tunnelling companies on the western front, were a brave lot and should be remembered as such.
How many on here would like to change places with them ?
If it can't be grown it has to be mined.
