I'm doing Facebook posts that follow my grandfathers path through Europe. My records show that shortly after he arrived in England, his unit went to an artillery range in Wales to calibrate their new 105mm howitzers.
I'm looking for any details about any artillery ranges in Wales. The first one I came up with was Castlemartin Training Area, but no real specifics about when units were there.
Any other known locations in Wales for Artillery practice?
