The Palmach (Hebrew: פלמ"ח, acronym for Plugot Maḥatz (Hebrew: פלוגות מחץ), lit. "strike forces") was the elite fighting force of the Haganah, the underground army of the Yishuv (Jewish community) during the period of the British Mandate for Palestine. The Palmach was established on 15 May 1941. By the outbreak of the Israeli War for Independence in 1948 it consisted of over 2,000 men and women in three fighting brigades and auxiliary aerial, naval and intelligence units.
