Absolutely,the risk taken,I think we all know about the Gestapo!
Whilst in Normandy last year I met a Belgian guy whose grandfather and
father helped to save a large no of Allied airmen. They were taken by the
Gestapo,his father escaped, but grandfather was never heard of again.
He showed me certificates signed by Eisenhower and Tedder commemerating their actions,after the war his father re-started the family
haulage business with surplus GMC'S,Diamond T's etc, he even had a
White halftrack.
