In Jewish underground circles, the plan was also variously called the "Plan for the North", "Masada on the Carmel", "Haifa-Tobruk", "Haifa-Masada-Musa-Dagh", or "Haifa Stronghold". The planners on the Palmach side were Yohanan Ratner and Yitzhak Sadeh. David Shaltiel (commander in Haifa at the time) and Yitzhak Gruenbaum were vocal supporters of a Masada-like stand, while Yigal Allon and others were skeptical of its usefulness. The evacuation of women and children to Cyprus was also considered.
