When I first started this thread I did not know where PG70 was but now, thanks very largely to the efforts of contributors on Rootschat, I not only know where it is but have been there and photographed it.
However, although I had many reasons to believe that my father had been in PG70 I struggled to find the last piece of evidence that would clinch it. That was until last week.
My father's sister, aged 99, died and amongst her personal papers we came across a picture of my father and, written on the back, his address in Italy.......P.G. 70, 2nd compound together with other postal details. So, there is now no real doubt where he was.
It's good to have brought the quest to a successful conclusion. I now need to discover a plan of the camp and see if I can discover where Compound 2 was
