When I was at Rheindahlen in the mid 80s we had our war headquarters in the caves at Maastricht. I went down there for the farewell do for the major who had commanded the signal group for 3 years. I asked him if he felt he'd achieved much during his time there. He said "You see that wall there, It's as if it's made of rubber and I've been pressing my shoulder against it for 3 years and I was halfway in and I've just stepped away and it's sprung back out" He was a great bloke and very switched on. Depressing.
