On 16 January 1948, a convoy of 38 men was sent by the Haganah to deliver supplies to the four blockaded kibbutzim of Gush Etzion, south of Jerusalem, following an Arab attack on January 14. The unit, named in Hebrew "Machleket HaHar" (lit. Mountain Platoon), set out on foot from Hartuv at 11 p.m. on January 15, commanded by Dani Mass. They took a detour around the Tegart fort-type Palestine Police station, to avoid detection by the British. Three were sent back because one man sprained an ankle, and two accompanied him. The remaining 35 were killed by Arab villagers and militiamen between the villages of Jaba' and Surif.
