In March 1944 Joseph was living in Debrecen and, as an apprentice in a printing house, he produced forged documents and distributed them to the members of youth movements as well as to refugees from Slovakia. In April 1944 Joseph was mobilized into a forced labor unit in Cegléd but in September he escaped with seventeen of his friends and arrived in Budapest where he joined the underground activities. Joseph went to the “Glass House” and from there he distributed forged documents all around the city. He was arrested and interrogated but managed to get released thanks to a Swiss “Schutzpass” (a Protection Document).
