(1) German term or phrase: Kinderlandverschickung 
A program the Nazis instituted during the war, to move children from 
big cities to the countryside in order to protect them from bombing 
raids and indoctrinate them more effectively. 
 
German Government evacuation scheme for children (Kinderlandverschickung) 
Explanation:
"Kinderlandverschickung" used to be a scheme on a great scale, which 
aimed to get children out of industrial/urban areas during the second 
World War. 
Children got allocated to families they didn't know at all and weren't 
necessarily related to, families that were living away from the usual 
target hot-spots and probably begrudged the fact that they had to look 
after another child during difficult times.
