Setting the scene
Saigon fell on April 30, 1975, when North Vietnamese tanks crashed through the gates of the Presidential Palace, ending the Vietnam War and reunifying Vietnam under communist rule. The fall came two years after the Paris Peace Accords and the withdrawal of U.S. troops. In March 1975, North Vietnam launched a major offensive, and South Vietnamese forces collapsed rapidly.
What happened
The U.S. conducted Operation Frequent Wind, the largest helicopter evacuation in history, airlifting 7,000 Americans and South Vietnamese from Saigon. Iconic images showed helicopters on rooftops and desperate Vietnamese trying to board. The last Americans left from the U.S. Embassy at 7:53 a.m. on April 30. North Vietnamese Colonel Bùi Tín accepted the surrender of South Vietnam's government.
Why it still matters
Saigon was renamed Ho Chi Minh City. The fall ended a 20-year American effort that cost 58,000 American and 2-3 million Vietnamese lives. It was a humiliating defeat that created the 'Vietnam syndrome'—American reluctance to intervene abroad. Over 1 million South Vietnamese fled as boat people in subsequent years. April 30 is celebrated in Vietnam as Liberation Day and mourned by Vietnamese Americans as Black April. The fall demonstrated the limits of American power and the strength of nationalist movements.
Background
