During World War i two camps for Muslim prisoners of war were
established in Wünsdorf and Zossen about 50km south of Berlin: the
Halbmondlager and the Weinberglager. In the Halbmondlager a mosque
was built and a cemetery for the prisoners was located in the nearby
village of Zehrensdorf. (Fig. 8.1) These efforts were not an end in itself,
but were part of the Jihad concept of the German Intelligence Office for
the East (NfO = Nachrichtenstelle für den Orient). This project intended to
persuade Muslim prisoners of war to change sides and join the Ottoman–
German Alliance against the British and French Entente.
