 Faced with Arab terror and British opposition, they devised a plan for a fortified settlement that could resist attack from its first night of existence.On 10 December 1936, Tel Amal was established as the first tower and stockade settlement (and the first kibbutz) in the Beit She'an Valley, and the second in all of Mandate Palestine after Kfar Hittim.During the next three years of troubles from the 1936–39 Arab revolt, some 52 such settlements were built overnight.
