Members of the Boys were slave labourers in the Natzweiler-Struthof concentration camp.
Natzweiler-Struthof concentration camp was operated by Nazi Germany. The camp had 64 subcamps.
The Boys were teenage and child-Holocaust survivors, who were brought to the UK after the war for rest and rehabilitation.
The camp was located in the Vosges mountains in Alsace in France. Alsace was annexed by Germany in 1940.
History
The camp had a number of functions as a labour camp, transit camp and place of execution. Few Jewish prisoners were held in the main camp and it is believed that the Boys spent time as slave labourers in its subcamps.
The Boys were brought to the Natzwiler-Struthof complex as slave labourers in 1944-45 and were transited to subcamps of the main camp.
