The Yehiam convoy attack occurred on March 27, 1948, during the 1947–48 Civil War in Mandatory Palestine.
A Haganah convoy had been sent from Haifa to reinforce and re-supply the kibbutz of Yehiam which was under attack by Arab forces.
Ben Ami Pachter (born 1919) planned to lead a convoy on 21 March 1948, from Kiryat Haim near Haifa because supplies were short and the defenders of Kibbutz Yehiam were running out of ammunition.
The 1947 United Nations Partition Plan for Palestine put Yehi'am within the limits of the Arab state rather than the Jewish one.
It is stated that in this action a column of six Jewish lorries were ambushed by 250 Arabs who were armed with rifles, two inch mortars, and light machine guns.
