 Following the 17 September 1948 assassination of Count Folke Bernadotte, it was over 20 hours before he imposed a curfew over Jewish Jerusalem and began arresting members of Lehi, the underground organisation believed to be responsible.One reason for this delay was the need to bring loyal troops from Tel Aviv into the city.On 20 October 1948, Dayan commanded the 800-strong Etzioni Brigade during the ill-fated "Operation Yeqev", in which the objectives were to join the Harel Brigade in the capture of the mountain range overlooking Beit Jala.
