He was released for nine days in February 1942 and allowed to return to Luxembourg, an episode which he later wrote about in his memoirs of the camp and which was turned into a film.

He then became involved in helping Luxembourg families who had fled to France ahead of the German forces to return to their home country.

He believed that this was part of a scheme to persuade six Luxembourgish priests to publicly voice their support for the Nazi regime.

He was definitively released on 5 August 1942,[1] apparently due to the intervention by his brother with senior Nazi officials in Paris.

After the war, he served as the editor of the Luxemburger Wort, held senior positions in the Catholic Church in Luxembourg, and received many awards.
