What this dot point is asking

VCAA expects you to explain why the war in Vietnam from the French defeat at Dien Bien Phu (1954) to the fall of Saigon (1975) became the most consequential American Cold War defeat. Strong responses pair the Cold War framing (containment, the domino theory) with the Vietnamese reality (a 30-year national liberation struggle led by the Vietnamese Communist Party), and cite at least one historian.

The answer

From the First Indochina War to Geneva (1945 to 1954)

Ho Chi Minh proclaimed Vietnamese independence in Hanoi on 2 September 1945 after the Japanese surrender, quoting the American Declaration of Independence. France returned to reassert its colony. The First Indochina War (December 1946 to July 1954) pitted the French Expeditionary Corps and a Vietnamese national government under former emperor Bao Dai against Ho's Viet Minh.

The decisive battle was Dien Bien Phu (13 March to 7 May 1954). Around 14,000 French troops under General Christian de Castries were besieged in a remote valley by Viet Minh forces under General Vo Nguyen Giap. The French surrendered on 7 May 1954, the day before the Geneva Conference opened.

The Geneva Accords (21 July 1954) temporarily divided Vietnam at the 17th parallel pending nationwide elections in July 1956. The Viet Minh withdrew to the north, the French and their allies to the south. Laos and Cambodia became independent neutral states.

The Republic of Vietnam under Diem (1954 to 1963)

The US backed Ngo Dinh Diem as Prime Minister of the State of Vietnam (later President of the Republic of Vietnam from 26 October 1955). Diem rigged a referendum to depose Bao Dai (98.2 per cent for Diem) and refused to hold the 1956 reunification elections, which the State Department believed Ho Chi Minh would win comfortably.

Diem's Catholic and Confucian-elitist government alienated the Buddhist majority and the peasantry. The Strategic Hamlet Program (1962) tried to separate peasants from the National Liberation Front (NLF, or "Viet Cong"), founded in Hanoi-directed organisation form on 20 December 1960. The Buddhist Crisis (May to November 1963) saw the self-immolation of monk Thich Quang Duc in Saigon on 11 June 1963 (the photograph by Malcolm Browne became iconic).

The Kennedy administration acquiesced in the coup of 1 November 1963 led by South Vietnamese generals. Diem and his brother Ngo Dinh Nhu were murdered the next day. Kennedy was assassinated three weeks later (22 November 1963). Lyndon Johnson inherited the war.

American escalation under Johnson (1964 to 1968)

The Gulf of Tonkin Incident (2 and 4 August 1964) saw the destroyer USS Maddox engage North Vietnamese torpedo boats; the second incident probably did not occur. The Gulf of Tonkin Resolution (7 August 1964) was passed by Congress 416 to 0 in the House and 88 to 2 in the Senate, authorising Johnson to use "all necessary measures" to repel attacks against US forces.

Operation Rolling Thunder began on 2 March 1965 (sustained bombing of North Vietnam). US Marines landed at Da Nang on 8 March 1965, the first overt American combat troops. By the end of 1965 there were around 184,000 US troops in Vietnam; the peak was around 543,000 in April 1969.

US strategy combined air bombardment (Rolling Thunder dropped around 864,000 tons of bombs on North Vietnam by November 1968) with "search and destroy" sweeps in the South under General William Westmoreland (Commander, US Military Assistance Command Vietnam, 1964 to 1968). The strategy was measured by "body count" rather than territory; corruption of the metric was endemic.

The Ho Chi Minh Trail through Laos and Cambodia, by which the Democratic Republic of Vietnam supplied PAVN and NLF forces in the South, was bombed continuously but never closed. The US dropped more bombs on Laos (around 2 million tons) than on any country in history.

The Tet Offensive (January to February 1968)

On 30 to 31 January 1968 (Tet, Vietnamese lunar new year), around 80,000 PAVN and NLF troops attacked more than 100 cities and towns across South Vietnam, including 36 of 44 provincial capitals. NLF commandos briefly entered the grounds of the US embassy in Saigon. The imperial city of Hue was held for 26 days (and the Hue Massacre saw around 2,800 residents killed by the NLF before recapture).

Tactically Tet was a defeat for the communists: around 45,000 PAVN and NLF troops were killed and the indigenous southern NLF infrastructure was largely destroyed. Politically Tet was an American disaster. It demonstrated that no part of South Vietnam was secure; it contradicted Westmoreland's confident "progress" briefings (November 1967).

CBS anchor Walter Cronkite, after a reporting trip to Vietnam, broadcast on 27 February 1968 that the war was "mired in stalemate." On 31 March 1968 Johnson announced a partial bombing halt, that he would seek peace talks, and that he would not run for re-election. Peace talks began in Paris on 13 May 1968.

Vietnamisation under Nixon (1969 to 1973)

Richard Nixon was inaugurated on 20 January 1969. His national security adviser Henry Kissinger ran negotiations with Hanoi's Le Duc Tho. "Vietnamisation" combined gradual American troop withdrawal with expanded South Vietnamese forces, intensified bombing of North Vietnam, and expanded operations against communist sanctuaries in Cambodia and Laos.

US ground troops fell from around 543,000 (April 1969) to around 156,000 (end of 1971) to around 24,000 (end of 1972). The secret bombing of Cambodia began in March 1969 (Operation Menu). The Cambodian Incursion (29 April to 22 July 1970) triggered the largest anti-war protests in American history; the Kent State shootings (4 May 1970) killed four students.

The Pentagon Papers (Daniel Ellsberg's leak to The New York Times, 13 June 1971) revealed decades of deception about the war's prospects. The My Lai massacre (16 March 1968, exposed in November 1969) further eroded support: around 504 unarmed Vietnamese civilians were killed; Lieutenant William Calley was convicted of 22 murders (March 1971) and served three years under house arrest.

The Easter Offensive (30 March to October 1972) saw PAVN forces invade South Vietnam in conventional formations; American airpower (Operation Linebacker) and South Vietnamese resistance contained the offensive. Linebacker II (the "Christmas Bombing" of Hanoi and Haiphong, 18 to 29 December 1972) brought Hanoi back to the table.

The Paris Peace Accords and the fall of Saigon (1973 to 1975)

The Paris Peace Accords were signed on 27 January 1973 by the US, the Republic of Vietnam, the Democratic Republic of Vietnam and the Provisional Revolutionary Government of South Vietnam (the NLF's political wing). The Accords provided for a ceasefire, a US withdrawal within 60 days, the return of American prisoners of war, and the political reunification of Vietnam through negotiation.

The Accords were a face-saving formula that allowed the US to disengage. PAVN forces in South Vietnam (around 150,000) were not required to withdraw. Nixon resigned over Watergate on 9 August 1974. President Gerald Ford requested 722 million dollars in supplemental aid for South Vietnam in early 1975; Congress refused.

PAVN launched its final offensive in March 1975. The South Vietnamese army collapsed faster than either side expected. Saigon fell on 30 April 1975. The last Americans were evacuated from the US embassy roof by helicopter (Operation Frequent Wind). The North and South were formally reunified as the Socialist Republic of Vietnam on 2 July 1976.

The war killed an estimated 1.1 million PAVN and NLF combatants, around 250,000 South Vietnamese soldiers, around 2 million Vietnamese civilians, around 58,200 Americans, and around 521 Australians (Australia committed up to 8,300 troops between 1962 and 1972).

Consequences

Indochina. Cambodia fell to the Khmer Rouge under Pol Pot on 17 April 1975; the subsequent genocide killed around 1.7 to 2 million people. Laos fell to the Pathet Lao in August 1975. Vietnam invaded Cambodia in December 1978 to topple the Khmer Rouge, fighting a 10-year war.

The United States. The War Powers Resolution (passed over Nixon's veto on 7 November 1973) limited presidential war-making to 60 days without Congressional approval. Conscription ended in January 1973. The "Vietnam Syndrome" constrained American military intervention until at least the 1991 Gulf War.

The Cold War. The Soviet Union and China both supported Hanoi but did not extract a strategic prize commensurate with the American defeat. The Sino-Soviet split (open from 1969) and Nixon's opening to China (Beijing visit, February 1972) showed that Vietnam was a regional defeat within a more complicated global game.

Historiography

Fredrik Logevall (Embers of War, 2012; Choosing War, 1999) emphasises American decisions were never inevitable. The US could have stayed out at multiple junctures (1945, 1954, 1961, 1965). Logevall won the Pulitzer Prize for Embers of War.

Lien-Hang Nguyen (Hanoi's War, 2012) uses Vietnamese sources to show the politics inside the Democratic Republic of Vietnam, including the dominance of Le Duan over Ho Chi Minh in the 1960s.

Marilyn Young (The Vietnam Wars 1945 to 1990, 1991) reframes the conflict as a Vietnamese war for independence into which the US intruded.

Mark Atwood Lawrence (The Vietnam War, 2008) is a standard short synthesis.

Common exam traps

Treating Vietnam as a single American war. The First Indochina War (1946 to 1954) was a French colonial war. The Second Indochina War (1955 to 1975) is the "Vietnam War" in American usage. The Vietnamese refer to the "American War" to distinguish it from earlier struggles.

Calling Tet a US victory. Tactically yes; strategically and politically a US defeat. Both can be true and the question matters.

Confusing the NLF with the PAVN. The National Liberation Front (Viet Cong) was the southern insurgent organisation founded in 1960. The People's Army of Vietnam (PAVN) was the regular North Vietnamese army. After Tet 1968, PAVN regulars increasingly dominated the conflict.

Saying America was defeated militarily. No major American military force was defeated in the field. The Paris Accords (January 1973) ended American combat. The collapse of the South in 1975 was a defeat of the Republic of Vietnam Armed Forces, after US Congress had cut aid.

In one sentence

The Vietnam War (1954 to 1975) escalated from the French defeat at Dien Bien Phu through American escalation under Johnson (Gulf of Tonkin Resolution, August 1964; up to 543,000 troops by April 1969) into the Tet Offensive of 30 January 1968 that broke American public support, Vietnamisation under Nixon, the Paris Peace Accords of 27 January 1973, and the fall of Saigon on 30 April 1975, killing around 3 million Vietnamese and 58,200 Americans and ending in a clear American Cold War defeat.

Practice VCAA10 marksEvaluate the reasons for American failure in the Vietnam War (1965 to 1975).
Show worked answer →

A 10-mark "evaluate" needs a thesis, multiple causes, and a named historian.

Thesis. The US failed in Vietnam for political, military and strategic reasons. The Saigon government lacked legitimacy; the war could not be won short of invading the North; American public support collapsed after Tet 1968.

Legitimacy. Ngo Dinh Diem and his successors never built popular legitimacy. Diem was Catholic in a Buddhist country; the Strategic Hamlet Program (1962) alienated peasants. The Buddhist Crisis (1963) ended in the US-approved coup that killed Diem (2 November 1963).

Strategic constraints. Johnson refused a ground invasion of the North (risking Chinese intervention). The Ho Chi Minh Trail could not be sealed by air. Operation Rolling Thunder (1965 to 1968) dropped more bombs than the US dropped in WWII without breaking Hanoi.

Tet (30 January 1968). Around 80,000 NLF and PAVN troops attacked over 100 cities. Tactically a communist defeat; politically a US disaster. Walter Cronkite declared the war stalemated; Johnson declined to run on 31 March 1968.

Domestic collapse. The Pentagon march (October 1967), Kent State (4 May 1970), the Pentagon Papers (June 1971), the War Powers Resolution (1973).

Vietnamisation. Nixon cut US troops from around 543,000 (1969) to zero (March 1973). The Paris Peace Accords (27 January 1973) ended American combat; Saigon fell on 30 April 1975.

Historiography. Fredrik Logevall (Embers of War, 2012) emphasises American choices were never inevitable. Lien-Hang Nguyen (Hanoi's War, 2012) uses Vietnamese sources for politics inside the North.

Conclusion. American failure was rooted in the unviability of the South Vietnamese state and the limits the Cold War placed on escalation.

Practice VCAA4 marksExplain the significance of the Tet Offensive (January 1968).
Show worked answer →

A 4-mark "explain the significance" needs the event and two consequences.

The event. On 30 to 31 January 1968 (Tet, the Vietnamese lunar new year), around 80,000 People's Army of Vietnam (PAVN) and National Liberation Front (NLF) troops attacked more than 100 cities and towns across South Vietnam, including Saigon (where they briefly entered the US embassy compound) and the imperial capital Hue (held for 26 days). The offensive was a tactical defeat: around 45,000 NLF and PAVN troops were killed and the southern infrastructure of the NLF was largely destroyed.

Significance. (1) Politically, it destroyed American public belief in the "light at the end of the tunnel" rhetoric of General William Westmoreland and the Johnson administration. Walter Cronkite's CBS broadcast on 27 February 1968 declared the war stalemated. President Johnson announced a bombing halt and declined to run for re-election on 31 March 1968. (2) Strategically, it forced the start of peace talks in Paris (May 1968) and the shift to Vietnamisation under Nixon from 1969.
