My paternal grandfather and Great grandfather served in the war. Great grandfather a lower officer with the Brittisch forces in WWI serving at Ypres. Grandfather Serving in the Belgium army.
Grandfather was lucky, in truth the only thing Belgian forces could hope to do was bravely fight and die to gain some time for the allies, he was a mortar gunner so when his brigade was completly overrun by Blitzkrieg they surrendered and he survived. Apparently back then the Gerry's didn't have time to take in POW's when busy performing their blitz, so uppon surrendering my Grandfather was told that he had to wait a few more hours until the troops handling the POW's (i gather the millitary police) arrived. BEcause he knew that surrendering to the Germans woul give hima one way ticket to a German labour camp he rather choose to sneak away in between and hide under the barn of my great grandfather at my grandmothers side. Grandpa and Grandma met there and Grandma had to bring food everyday and after the war the married.
Maternal Grandfather was the mayor of a city in Flanders. When the Germans came they installed a German favourite afcourse. He was a caring and a pragmatic man, he had been very succesfull in bussiness and so it allowed him to help a lot of people during the war which only made him more popular afterwards.
Because business had to keep on during the war, and because the Germans had introduced their own money into Belgium, at the end of the war my Grandfather had the issue that practicly all his wealth was now in reichsmarks. As to save the bussiness he had to whitewash that money at a 50% return rate trough the catholic church.
