After the
German invasion of Poland he tried, with help from the
British embassy to escape on a ship to
Sweden. However, he was arrested by the
Germans and imprisoned in
Berlin. Later, he was transferred to the
Warsaw Ghetto. In the ghetto, Orzech worked for the charitable organization
Joint. He also worked on the production of
underground newspapers, including the Bundist
Der Verker. In April 1942, the Germans began mass executions in the ghetto, supposedly as a way of combating underground literature. Orzech was summoned by
Judenrat president
Adam Czerniaków and asked that the Bund cease circulating its illegal newspapers. Orzech also wrote bulletins and proclamations to the residents of the ghetto not to trust the Germans and not to volunteer for supposed "labor in Germany" from the
Umschlagplatz (which was in fact a collection point for deportation to the
Treblinka extermination camp) He, along with
Leon Feiner, wrote the telegram which informed the Bundist member of the
Polish government in Exile,
Szmul Zygielbojm, about the outbreak of the
Warsaw Ghetto Uprising. ==Death==
