See it on the Battles & Wars map →What happened
After US troops left in 1973, fighting resumed. In March 1975 North Vietnam launched a major offensive and South Vietnam's army collapsed faster than either side expected. As forces closed on Saigon, the US ran Operation Frequent Wind, the largest helicopter evacuation in history, flying out about 7,000 Americans and South Vietnamese in roughly a day. On April 30 a tank crashed through the gates of the Presidential Palace and the South surrendered. Saigon was renamed Ho Chi Minh City.
Why it matters
It ended three decades of war in Vietnam, set off a refugee exodus of 'boat people', and became a lasting image of American defeat.
How we know
Photographs and film of the rooftop evacuations, US embassy cables, Vietnamese official accounts, and testimony of evacuees and soldiers.
Still debated
Whether more US aid in 1974–75 could have saved South Vietnam, and how many people died in 're-education camps' afterward, is debated.
Connections (2)
▸Tet Offensive began the US disengagement that preceded Fall of SaigonMostly agreed
The connection
Tet set off a chain: Johnson's de-escalation, Nixon's phased troop withdrawals, the 1973 Paris Peace Accords and the US exit. With US troops gone and Congress cutting aid, South Vietnam faced the North largely alone and collapsed in 1975.
When and how
From 1968 to 1975: peace talks in Paris from May 1968, accords signed January 27, 1973, and Saigon's fall on April 30, 1975.
How sure are we?
Each decision in the sequence is well documented, but tying Tet directly to a fall seven years later involves judgment, hence 'mostly agreed'.
Debates and open questions
Whether South Vietnam could have survived with continued US air power and aid, as Nixon had privately promised, is debated.
▸Fall of Saigon ended Vietnam WarWell documented
The connection
The capture of Saigon and South Vietnam's surrender on April 30, 1975 ended the war. Vietnam was formally reunified as the Socialist Republic of Vietnam in July 1976. Communist movements also took power in neighboring Cambodia and Laos in 1975.
When and how
Saigon, April 30, 1975; South Vietnamese President Duong Van Minh surrendered at the Presidential Palace (Independence Palace), now called Reunification Palace.
How we know
The surrender is recorded in film, photographs and official accounts from all sides.
Debates and open questions
For Cambodia and Laos, fighting and suffering continued long after 1975, so where 'the war' ends depends on whose story is told.
