The Kfar Etzion massacre refers to a massacre of Jews that took place after a two-day battle in which Jewish Kibbutz residents and Haganah militia defended Kfar Etzion from a combined force of the Arab Legion and local Arab men on May 13, 1948, the day before the Israeli Declaration of Independence. Of the 127 Haganah fighters and Jewish kibbutzniks who died during the defence of the settlement, Martin Gilbert states that fifteen were killed on surrendering.
