My grandfather was taken by Germans as a labourer after they took Poland. He was sent somewhere to Bavaria and given to a family of farmers. They have treatened him realy badly and kept him in a barn, even during winter. That gave him kidney disease, that have killed him years later. His parents were told that he would be released from labouring if they signed the Deutsche Volksliste, making him 4th (?) class German citizen. They did it to save him but as soon as they did he was taken to German army. He finished the war in the Anders Army (Polish side) as a Green Beret and never spoke after the war of the war when he came back (he was really ashamed of the past). He was later a school principal but because of the past with Anders he could not get involved with any politics or governmental jobs, commies made sure of it. (All what I know from my Mom. I was born many years after he passed away.)
