The term Kinderlandverschickung (KLV) was first used in the late 19th century to describe the foster care relocation of sick and underprivileged children to the countryside. At the outbreak of WWII, although there were no large scale civilian evacuations as in Britain,
the National Socialist People’s Welfare (NSV) organized the relocation of mothers with very young children, with or without older siblings (and some pregnant women) to host families in safer areas. The relocation of children aged 10-14 years was the responsibility of the Hitler Youth.
Due to lost records, the total number of evacuations during the war is unknown but in 1943, a senior official in the Hitler Youth estimated about three million children and young people (including 1 million in KLV camps) had been evacuated.
My next door neighbor was about 9-10 when when the SS buses came to her city . Her family of 4 was taken to a farm in rural Bavaria and dumped off. She recalled the resentment her “hosts” had and the meager food they had to survive on.
