In 1942 the threat of a German invasion from the South increased with the Afrika Korps advance into Egypt. Yishuv leaders discussed plans to defend against genocide of the Jewish population by the German army and by local Nazi supporters which was expected in the event of British retreat from Palestine. The Hagana's "Plan of the North" included use of Palestine Final Fortress structures. The Yishuv also called their plan "Masada on the Carmel" and "Haifa-Masada-Musa Dagh". Although the Yishuv had cause for worry during the 200 days of dread, no further actions were taken by the British nor by the Yishuv to prepare against possible invasion by the Axis powers. In late 1942 the threat of invasion from the south was lifted following the Allied victory in the Second Battle of El Alamein and the subsequent German retreat westwards across North Africa.
