The mission of the *Amicale des anciens déportés de Buchenwald*, established in July 1945, just three months after the camp's liberation, centered on three core principles: Union, Unity, and Usefulness. The organization aimed to foster solidarity (Union) among former deportees to uphold the ideals of the Resistance, promote effectiveness (Unity) through a unified front, and provide official recognition and assistance (Usefulness) to survivors and their families. Led by Colonel Manhès, with notable resistance figures like Marcel Paul, Maurice Jattefaux, Gaston Weill, and Jean de Rudder as vice-presidents, all members of the first leadership were active in the French Resistance and had been involved in the *Comité des Intérêts Français* (CIF) during their internment. Their mission was not only to support survivors but also to preserve the memory of the Resistance and honor the commitment made during their ordeal.
