Cold War Files: All Units: Events: Operation Frequent Wind Calls for Saigon Evacuation

NVA shell Tan Son Nhut air base in Saigon, killing two U.S. Marines at the compound gate. Conditions then deteriorate as South Vietnamese civilians loot the air base. President Ford now orders Operation Frequent Wind, the helicopter evacuation of 7000 Americans and South Vietnamese from Saigon, which begins with the radio broadcast of the song "White Christmas" as a pre-arraigned code signal.

At Tan Son Nhut, frantic civilians begin swarming the helicopters. The evacuation is then shifted to the walled-in American embassy, which is secured by U.S. Marines in full combat gear. But the scene there also deteriorates, as thousands of civilians attempt to get into the compound.

Three U.S. aircraft carriers stand by off the coast of Vietnam to handle incoming Americans and South Vietnamese refugees. Many South Vietnamese pilots also land on the carriers, flying American-made helicopters which are then pushed overboard to make room for more arrivals. Filmed footage of the $250,000 choppers being tossed into the sea becomes an enduring image of the war's end.
