The fall of Saigon: How the Vietnam War came to a dramatic end

The Vietnam War was one of the Cold War’s most drawn-out conflicts – but even its end was traumatic, as communist forces raided the city of Saigon in 1975.

For the United States, starting a war is one thing. When that same war starts looking like an unmitigated disaster, getting out of it in a face-saving way is something else entirely. Today, the best-known example of an infamous overseas military campaign remains the Vietnam War.

The Vietnam War waged for more than a decade between communist North Vietnam and US ally South Vietnam. The former eventually captured the latter’s capital, Saigon in April 1975 – setting the stage for the two disparate Vietnamese states to unify under communist rule.

As the North Vietnamese army closed in, US personnel and South Vietnamese citizens were hurriedly evacuated in their thousands by helicopter. We at Sky HISTORY are always gripped by video footage of Saigon’s fall, so what makes it one of the Cold War’s most climactic moments?

How did the Vietnam War begin?

The Southeast Asian country of Vietnam gained independence from the French at the 1954 Geneva Conference, but was partitioned into two separate states. The communist revolutionary Hồ Chí Minh was at the helm of North Vietnam (officially named the Democratic Republic of Vietnam) until his death in 1969.

In sharp contrast to this socialist state was its southern neighbour the Republic of Vietnam, colloquially referred to as South Vietnam. The anti-communist United States financially supported South Vietnam as a bulwark against North Vietnam, which was closely aligned with the Soviet Union and China.

These were far from the only powerful allies North Vietnam had by its side. A united front organisation called the Viet Cong lay lurking on South Vietnamese territory, eager to seize it for the North. They would team up with North Vietnam’s national military force, the People’s Army of Vietnam, in pursuit of this goal.

The White House feared that such a takeover of Vietnam would have a domino effect bringing yet more Asian countries into the communist orbit. Hence, the US increasingly sent troops of its own to South Vietnam to counter those units fighting for the North.

Optimism turns into despair

The United States escalated its military involvement in Vietnam in 1964. US fighter pilots bombed North Vietnam heavily in the 1960s, and the administration of then-US President Lyndon B Johnson spoke of promising progress.

However, unvarnished press reports coming out of war-ravaged Vietnam told the American public a very different story. Especially distressing was news of the Tet Offensive, where South Vietnamese targets suffered surprise attacks in 1968.

Over time, the White House’s claims of imminent victory started to look increasingly hollow. Observers on US soil clamoured for peace, and in 1968, Richard Nixon won the US presidential election on a platform of ending the war.

The ‘peace’ that never was

After taking office in January 1969, Nixon pursued a policy of ‘Vietnamisation’. The idea was that the US would significantly reduce its military presence in South Vietnam as native soldiers took up more of the slack. Peace accords were even signed in 1973.

In practice, terms of the peace agreement were quickly violated by both halves of Vietnam. North Vietnam tested US resolve by launching major offensives. By early 1975, communist forces were snapping up land deep into South Vietnamese territory – and Saigon was in their sights.

Saigon surrenders

Many in Saigon feared that if they remained in Vietnam for much longer, they would be subjected to bloody reprisals by the communists.

Despite at first hoping that the advancing North Vietnamese could still be held off, Graham Martin – the US ambassador to South Vietnam – eventually relented. Operation Frequent Wind evacuated more than 7,000 people from Saigon across 29th and 30th April 1975, with helicopters airlifting these passengers to American ships.

On 30th April, a North Vietnamese tank smashed through the gates of the South Vietnamese Presidential Palace. The Saigon administration formally surrendered, and the Vietnam War was over.

The aftermath and legacy of Saigon’s fall

Today, Saigon is officially Ho Chi Minh City, having been renamed by the victorious communists. Nonetheless, it continues to be casually referred to by its former, historical name.

The fall of Saigon has left an indelible imprint on public memory. While Vietnam itself now celebrates 30th April as ‘Reunification Day’, South Vietnamese émigrés have remembered it as ‘Black April’ and the ‘National Day of Shame’.
