In 1946, in response to the refusal to allow 100,000 European Jews who had survived the Holocaust to enter Palestine, David Ben-Gurion ordered Jews in the region to rise up against the British authorities. The rebels' first operation was the "Night of the Bridges" - formally Operation Markolet.
At the time, British Foreign Secretary Ernest Bevin said that a whole division was required in Palestine to ensure the security of the resettling immigrants, something that would cause the outbreak of anti-Semitic sentiment and something apparently too costly for the post-war period.
The leaders of the Jewish communities then decided to prove to London that the policy of prohibiting entry would be much more harmful. Eleven bridges connecting Palestine to other states were to be blown up.
The bombing of the bridges was proposed by the Jewish military specialist Ygal Allon and planned by operational officer Dov Cesis. One of Israel's legendary founding fathers, David Ben-Gurion, was a supporter of the operation.
Nine bridges were completely blown up, and one was badly damaged. On the eleventh bridge, a bullet hit an explosive device during a clash with a police patrol, and some 14 demolition men were killed.
Operation Markolet triggered a large-scale police operation against Jewish settlers and accelerated the withdrawal of British troops from Palestine.
