November 25, 1940- The SS Patria, with 1,900 desperate immigrants aboard, blew up and sank in Haifa port. 267 refugees were killed. The explosion was the work of the Jewish underground army, the Hagana, who had meant only to damage the ship to prevent its sailing but had miscalculated the amount of explosives needed to disable the ship. Many say that this was no miscalculation and was deliberate murder of Jews by Jews, in an attempt to influence British immigration policy to Palestine.
