1948: While attempting to reach Mount Scopus on April 13, a convoy of Hadassah and Hebrew University doctors, nurses and other personnel are ambushed. Besieged and under fire for hours, in the end 78 people are killed, among them HMO Director Dr. Haim Yassky. Unable to guarantee the safety of its patients or staff, Hadassah evacuates all its facilities on Mount Scopus, relocating all departments to five makeshift hospitals in temporary quarters around Jerusalem. Hadassah's access to Mount Scopus is lost for the next 19 years.
