To the left of the memorial are two men bent over under the weight of a heavy iron bar, and to the right are the burning Krupp factories with the letter K in a tri-lobe and a man lying down, evoking the tragedy.

Most of the prisoners at the Deckenschule camp in Essen (Germany) were Belgians, mainly French-speakers from the Arlon and Liège prisons. On 25 August 1944, the last convoy from the Deckenschule camp arrived from Arlon. It included around 40 hostages who were arrested on 15 August in the Saint-Hubert region (Arville, Lorcy, Hatrival and Smuid).

A few months later, on Monday 23 October 1944 at around 17:30, a bomb fell on the Krupp factories. Many prisoners were injured or killed as a result. Some died a few days later as a result of their injuries. The survivors of the bombing were sent to the Neerfeld camp. On Wednesday 11 April 1945, the camp was liberated by American forces.  

Following the conflict, Saint-Hubert was chosen as a place of remembrance for the victims of the camps due to its central position in the province of Luxembourg. On 9 February 1948, the bodies of 60 victims were repatriated to the town. A total of 26 bodies were identified. They were buried in their village or town cemeteries. The 34 unidentified bodies were buried in the main lawn of Saint-Hubert cemetery. Twelve years later, the remains were transferred one last time to the vault below the memorial.
