Operation Frequent Wind Evacuates Saigon
With North Vietnamese forces closing in on the South Vietnamese capital in late April 1975, U.S. Ambassador Graham Martin ordered the final helicopter evacuation of American personnel and at-risk Vietnamese allies. On April 29, after shelling damaged runways at Tan Son Nhut, Armed Forces Radio played “White Christmas” as the coded signal to begin Operation Frequent Wind. Marines secured landing zones at the U.S. embassy and DAO compound while CH-53 and CH-46 helicopters ferried evacuees to Seventh Fleet ships offshore in the largest such operation in history. Over the next day, more than 7,000 people, including thousands of Vietnamese, were lifted out before the city fell.
