Operation Vulture was the name of the proposed U.S. operation that would rescue French forces at the Battle of Dien Bien Phu in 1954 via B-29 raids based in the Philippines. The French garrison had been surrounded by the Viet Minh during the First Indochina War. When the British government refused to give its support, the plan was cancelled and as a result the French Army organised Operation Condor, an attempt to weaken the Viet Minh artillery's assaults against the besieged French Union garrison.
