Looks like a good read there
I've had a copy of this since the 1970s don't know where I got it from.

My now departed elderly German neighbour reminisced a few times of his service in the artillery, training with 105mm guns , doing the ranging and so on. He ended up in Italy where he was captured. He said he set fire to the ammo dump he and his mate was guarding as the Allies approached , in that case being Free French troops. He said the Allies plastered a nearby hill with a massive barrage but there was nothing there of any military significance ! He said his unit had forgotten about himself and his mate , they were just left to fend for themselves. He said driving trucks was particularly dangerous in daytime because of Allied fighter Bomber threats. He begged his sergeant to be sent to Nth Africa .. anywhere but the Russian front.
