A “national defense scheme” for the Jewish population in Palestine authored by Elimelech ‘Avner’ Zelikowitz, a member of the Haganah, the largest Zionist militia, in June 1937. The plan was prepared in response to a request by Haganah leadership, ahead of the possible termination of the Mandate for Palestine and outbreak of a Jewish-Arab civil war. The scheme detailed the military, financial and territorial outlines of the Jewish war effort, based on a phased advancement from north to south.
