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 Bunzlau concentration camp a subcamp of the Gross Rosen concentration camp.
As the camps were dissolved 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.
The camp was evacuated on 10/11 of February 1945.
After a few weeks of marching 541 prisoners arrived at the Mittelbau-Dora concentration camp, where their transport was refused on 15 March 1945.
The prisoners were loaded into open carriages, and taken to Bergen-Belsen and Buchenwald.
How many prisoners were alive by the time they reached Bergen-Belsen, and how many were liberated by the British Army is unknown.
