Members of the Boys were slave labourers in the Allendorf labour camp, a subcamp of the Buchenwald concentration camp.
Buchenwald concentration camp was operated by Nazi Germany. The camp had 139 subcamps.
The Boys were teenage and child-Holocaust survivors, who were brought to the UK after the war for rest and rehabilitation.

Since 1940, a total of over 17,000 forced labourers were employed at the Allendorf industrial site. From August 1944, this included around 1,000 Jewish female slave labourers from Hungary and Slovakia who had to manufacture grenades in the factory of the Gesellschaft mbH zur Verwertungchemischer Produkte (Verwertchemie for short), a subsidiary of Dynamit AG.
The camp was abandoned on March 1945 and the detachment was evacuated.
From the files it is no longer possible to determine the destination of the evacuation march. The march first headed east, toward Ziegenhain, and then northeast, toward Fritzlar. Throughout the march, groups of prisoners ran off, as did guards. The whole detachment eventually dissolved.
Memorialisation
Today, the Stadtallendorf Documentation and Information Centre is located at the former site of the camp.
