Members of the Boys were held in Nazi labour and concentration camps and used as slave labourers.
From 1933-1945 Nazi Germany operated over 1,000 concentration camps and subcamps in its own territory and across German occupied Europe. Among them was the Hanover-Ahlem subcamp of the Neuengamme concentration camp.
As the camps were evacuated thousands of people, among them members of the Boys, endured horrific evacuations from the camps on foot, in freight wagons and open top trains, as well as perilous journeys across the Baltic Sea.
The Boys were teenage and child-Holocaust survivors, who were brought to the UK after the war for rest and rehabilitation.
On 6 April 1945, those prisoners who were still able to walk left the concentration camp on foot. Six-hundred men set off in the direction of Bergen-Belsen. It is not known how many prisoners were murdered by SS men along the way. They arrived in Bergen-Belsen on 8 April 1945.
