They were taken to the Niedersachswerfen SD headquarters, where Naegelé attempted to beat confessions out of the other prisoners.[6] Debeaumarché was sentenced to death on 11 November 1944, but the sentence was not carried out. Instead Debeaumarché was held in solitary confinement, accused of anti-Nazi plotting. In April 1945 he was moved to Bergen-Belsen, where he was liberated during the advance of Allied troops on 15 April 1945 and repatriated to France.[2] On 1 May 1945 he marched down the Champs-Élysées alongside fellow Buchenwald-captive Pierre Dejussieu-Pontcarral.[7]
