My Grandmother's brother Richard Klein was captured and sent with two German soldiers to a very distant and isolated farm in Siberia. They were going to freeze to death when Richard argued that if the helped the Russian peasants to improve their farm then maybe they would get better accommodation. This worked and they moved into a space in a barn they had worked before the winter set in.
They survived the war but did not get help to get home when they eventually were told the war was over. He arrived back home in a terible state and his own mother refused him entry believing he was a tramp or vagabond. He tried again and the old woman who had been hsi nurse recognised him and brought him round to the back of the house, where she cleaned him up, dressed him and presented him to his mother. He was broken and never did another days work in his life. His brother Percy (Berthold) Klein looked after him for the rest of his life moving with them to New York in 1938. He is on the 1940's census.
