Vietnam War

• 1. Introduction

  ›

  The Vietnam War began on the 1st of November 1955 and did not end until the 30th of April 1975 - nearly two decades of armed conflict across Vietnam, Laos, and Cambodia that would consume millions of lives and reshape the world order. At its heart, this was three wars at once: a civil war between two Vietnamese governments, a proxy battle between the United States and the Soviet Union, and one of the postcolonial struggles for national liberation that defined the mid-twentieth century.

  The price paid was staggering. Estimates of Vietnamese soldiers and civilians killed range from 970,000 to 3 million. Some 58,220 American service members died. Between 275,000 and 310,000 Cambodians perished, along with 20,000 to 62,000 Laotians. And when the fighting finally stopped, the dying did not. The Indochina refugee crisis that followed saw millions flee, with about 250,000 perishing at sea.

  How did a conflict rooted in anticolonial nationalism become a war that the United States poured more than half a million troops into? How did North Vietnam, outgunned and outspent, bring a superpower to its knees? And what did the war leave behind - in the soil, in the bodies of survivors, and in the fractured politics of a country whose leaders declared victory but could never fully explain what they had won?

• 2. Colonial Roots and the First War

  ›

  Vietnam had been under French control as part of French Indochina since the 1880s, and the resistance that eventually became the Vietnam War grew from seeds planted long before any American soldier set foot in Southeast Asia. Nguyen Sinh Cung established the Indochinese Communist Party in 1930, with the explicit aim of overthrowing French rule and establishing a communist state. He would later be known to the world as Ho Chi Minh.

  Japan's invasion of French Indochina in September 1940 reshuffled the deck. By 1941, Japan had gained full military access and established a dual colonial rule alongside a weakened Vichy French administration. Ho Chi Minh returned from exile to build the Viet Minh movement, which the US Office of Strategic Services equipped and trained as an intelligence asset against Japanese forces.

  When Japan surrendered, Ho moved quickly. The Viet Minh launched the August Revolution, seized weapons from the Japanese, and on the 2nd of September Ho declared the independence of the Democratic Republic of Vietnam. British forces, deployed to manage the Japanese surrender south of the 16th parallel, supported a French coup on September 23 that overthrew the DRV government in Saigon and reinstated French control.

  Full-scale war between the Viet Minh and France erupted in December 1946. By 1950, the Cold War had fully colonized the conflict: China became the first state to recognize Ho's government, the US recognized the French-backed State of Vietnam, and Washington began shouldering French war costs. By 1954, the US had spent one billion dollars supporting the French effort - 80 percent of the total war costs.

  The war ended at Dien Bien Phu in May 1954, where Viet Minh forces encircled the French garrison using heavy artillery and anti-aircraft batteries. France surrendered. The 1954 Geneva Conference that followed affirmed the independence of Vietnam but divided it at the 17th parallel - a temporary partition that both sides understood would set the terms for the next war.

• 3. Two Vietnams Take Shape

  ›

  The Geneva Accords of 1954 were supposed to produce a unified Vietnam through elections within two years. Instead, they produced two entrenched governments that would spend the next two decades fighting for survival. Neither the United States nor the State of Vietnam signed anything at the Geneva Conference.

  In the North, Ho Chi Minh's government carried out agrarian reforms that turned brutal. North Vietnamese witnesses suggested a ratio of one execution for every 160 village residents during land reform. Scholars settled on a figure of around 50,000 executions, though documents from Vietnamese and Hungarian archives suggest the true number, while significant, may have been lower than 14,000. In 1956, Hanoi admitted to "excesses" and restored much of the confiscated land to its original owners.

  In the South, Ngo Dinh Diem consolidated power through methods that were scarcely more democratic. In a referendum in October 1955, he rigged the vote, overseen by his brother Ngo Dinh Nhu, and was credited with 98 percent of the vote - including 133 percent in Saigon. His American advisors had quietly recommended a more modest margin of 60 to 70 percent. Diem declared South Vietnam the Republic of Vietnam and named himself president.

  During the 300 days following Geneva, up to one million Northerners moved South, including at least 500,000 Catholics, approximately 200,000 Buddhists, and tens of thousands from ethnic minority communities. Meanwhile, the Viet Minh left roughly 5,000 to 10,000 cadres in the South as the foundation for a future insurgency.

  President Eisenhower later speculated that up to 80 percent of Vietnamese voters would have supported Ho Chi Minh in a free 1954 election. In 1957, observers from India, Poland, and Canada representing the International Control Commission reported that fair elections were impossible - neither side had honored the armistice. The division that was meant to be temporary had calcified into two permanent states, each determined to eliminate the other.

• 4. The Insurgency Ignites

  ›

  In April 1957, communist insurgents launched an assassination campaign in South Vietnam. Douglas Pike estimated they carried out 2,000 abductions and 1,700 assassinations of officials, village chiefs, hospital workers, and teachers between 1957 and 1960. Violence between insurgents and government forces escalated from 180 clashes in January 1960 to 545 by September.

  In May 1958, North Vietnamese forces seized the transportation hub at Tchepone in southern Laos, establishing the Ho Chi Minh Trail - initially a six-month mountain trek - to move men and supplies south. Group 559 was set up to manage and expand the trail, and the first arms delivery to southern forces was completed in August 1959. About 500 regroupees were sent south during the trail's first year of operation.

  North Vietnam formally created the Viet Cong in December 1960, uniting all anti-government insurgents under a single front headquartered in Memot, Cambodia. By the end of 1964, VC ranks had grown from approximately 5,000 at the start of 1959 to about 100,000. From a strength of approximately 5,000 at the start of 1959 the Viet Cong's ranks grew to about 100,000 at the end of 1964 - a twenty-fold expansion over five years.

  Diem's response made things worse. His "Denounce the Communists" campaign, launched in July 1955, led to mass imprisonments. The North Vietnamese government claimed that by November 1957, over 65,000 had been imprisoned and 2,148 killed. By 1959-40,000 political prisoners were behind bars. His Strategic Hamlet Program from 1962, which forcibly relocated rural South Vietnamese into fortified villages to isolate them from the Viet Cong, generated deep resentment among the peasantry it was supposed to protect.

  Diem's political crisis came to a head in May 1963 when ARVN forces shot nine Buddhists protesting the ban on displaying the Buddhist flag. Mass protests erupted. In August, ARVN Special Forces raided pagodas across the country, killing hundreds. Washington's patience had run out. On the 2nd of November 1963, Diem was overthrown and executed along with his brother - and South Vietnam entered a period of political instability that would see one military government topple another in rapid succession.

• 5. America Goes to War

  ›

  On the 8th of March 1965, 3,500 US Marines waded ashore near Da Nang, marking the beginning of America's ground war. Their initial assignment was defensive: protect Da Nang Air Base. Within nine months, that first deployment had swelled to nearly 200,000. By 1966, the number had reached 184,000, and by 1969, 536,000.

  The Gulf of Tonkin incident had provided the political justification for this escalation. On the 2nd of August 1964, North Vietnamese torpedo boats fired on a US destroyer on an intelligence mission along North Vietnam's coast. A second attack was reported two days later. An NSA publication declassified in 2005 revealed there was no second attack. But it prompted Congress to pass the Gulf of Tonkin Resolution on the 7th of August, granting President Johnson authority to expand military action without a formal declaration of war.

  General William Westmoreland drove American strategy toward attrition - wearing down the enemy through search and destroy operations and measuring success by body count. Between 1965 and 1968, Operation Rolling Thunder deluged the North with a million tons of missiles, rockets, and bombs. The objective was to force North Vietnam to stop supporting the Viet Cong by threatening to destroy its air defenses and infrastructure. The bombing campaign lasted three years. North Vietnam did not stop.

  Between 1964 and 1973, the US also dropped two million tons of bombs on Laos alone - comparable to the 2.1 million tons it dropped across Europe and Asia during all of World War II - making Laos the most heavily bombed country in history. The Chief of Staff of the Air Force, Curtis LeMay, wrote that the US was going to "bomb them back into the Stone Age". The VC's supply lines kept flowing.

  By 1967, the war had generated 2 million internal refugees in South Vietnam. Operation Masher, the largest search and destroy operation to that point, evacuated and rendered homeless 125,000 people - and the PAVN/VC returned to the province just four months later. The VC and PAVN initiated 90 percent of large firefights, retaining strategic initiative despite the overwhelming US military presence.

• 6. Tet and the Turning Point

  ›

  In late 1967, PAVN forces drew American troops toward the Central Highlands through diversionary fighting at Dak To and the Marine base at Khe Sanh. Meanwhile, preparations were quietly underway for the most ambitious communist offensive of the war. In January 1968, over 85,000 VC and PAVN troops struck more than 100 cities simultaneously, attacking military installations, headquarters, and government buildings, including the US Embassy in Saigon.

  Peter Arnett reported an infantry commander's remark about the Battle of Ben Tre: "it became necessary to destroy the village in order to save it." The offensive constituted, in the assessment of American commanders themselves, an intelligence failure on the scale of Pearl Harbor. Most cities were recaptured within weeks, but Hue held out for 26 days. There, PAVN/VC forces executed approximately 2,800 unarmed civilians, ARVN prisoners, and foreigners they considered spies. American forces employed massive firepower in response, leaving 80 percent of the city in ruins.

  The Tet Offensive was a tactical defeat for North Vietnam - the general uprising Le Duan had expected never materialized, ARVN units did not defect in significant numbers, and communist losses across the offensive cycle reached 45,267 killed and 111,179 total casualties, mostly Viet Cong. But its political impact in the United States was decisive. Public approval of Johnson's handling of the war dropped from 48 percent to 36 percent. Endorsement for the war overall fell from 40 percent to 26 percent.

  In November 1967, Westmoreland had told the National Press Club that "the end comes into view." The public's shock at Tet was amplified by that assurance. In March 1968, Westmoreland was removed from command, succeeded by his deputy Creighton Abrams. On the 10th of May, peace talks between the US and North Vietnam opened in Paris. Johnson did not run for re-election. The Vietnam War had effectively ended his presidency.

• 7. Vietnamization and Collapse

  ›

  Richard Nixon won the 1968 presidential election claiming to have a secret plan to end the war. His approach, which he called Vietnamization, transferred combat responsibility to an expanded ARVN while withdrawing American troops. In 1970, Nixon announced the reduction of an additional 150,000 American troops, bringing numbers down to 265,500. By 1971, Australian and New Zealand forces had also left, and US troop strength stood at 196,700.

  American military morale collapsed in parallel with the troop withdrawals. Desertion rates quadrupled from 1966 levels. ROTC enrollment dropped from 191,749 in 1966 to 72,459 by 1971, and to a low of 33,220 by 1974. Drug usage spread: 30 percent of troops regularly used marijuana, and a House subcommittee found 10 percent used heroin. Approximately 900 fragging - the killing of a fellow officer, usually a superior - and suspected fragging incidents were investigated, most between 1969 and 1971.

  In 1972, North Vietnam launched a conventional invasion with 300,000 troops and hundreds of tanks in the Easter Offensive. The US provided critical air support through Operation Linebacker, halting the advance at heavy cost to both sides. Henry Kissinger reached a peace agreement with North Vietnam's Le Duc Tho in October 1972, but South Vietnam's President Thieu demanded changes. Nixon ordered Operation Linebacker II, a bombing of Hanoi and Haiphong in December, to force Hanoi back to the table. The Paris Peace Accords were signed on the 27th of January 1973. All US forces withdrew by March.

  The accords were violated almost immediately. South Vietnam's economy, dependent on US support, was badly damaged by the 1973 oil crisis. Congress cut financial aid from one billion dollars per year to 700 million. On the 10th of March 1975, General Van Tien Dung launched Campaign 275 into the Central Highlands. The ARVN collapsed. On the 30th of March, 100,000 leaderless ARVN troops surrendered as the PAVN marched through Da Nang. By the 27th of April, 100,000 PAVN troops encircled Saigon, which was defended by roughly 30,000 ARVN troops.

  Operation Frequent Wind, the largest helicopter evacuation in history, began lifting civilians and diplomatic personnel from Tan Son Nhut and the embassy compound. In the morning of the 30th of April, the last US Marines evacuated the embassy. PAVN tanks crashed through the gates of the Independence Palace, and President Duong Van Minh surrendered to Lieutenant Colonel Bui Van Tung, political commissar of the 203rd Tank Brigade. Minh was escorted to Radio Saigon to announce the surrender, and his statement went on air at 2:30 pm. North and South Vietnam were officially reunified in 1976.

• 8. Aftermath and Long Shadow

  ›

  The war's physical legacy was written into the land itself. Twenty percent of South Vietnam's jungle was sprayed with toxic herbicides, leading to significant health problems that persisted for generations. Between 1964 and 1973, Laos received two million tons of American bombs - a scale of destruction that made it, by that measure, the most heavily bombed country in history.

  The postwar political repression and flawed economic policies of the unified Vietnamese government drove the refugee crisis known as the Vietnamese boat people. Millions left Indochina; about 250,000 perished at sea. The Khmer Rouge, which had come to power in Cambodia partly through the disruptions caused by the war, carried out the Cambodian genocide. The Cambodian-Vietnamese War began in 1978, and China invaded Vietnam in response, with border conflicts lasting until 1991.

  Within the United States, the war produced what came to be called Vietnam syndrome - a deep aversion to overseas military involvement that shaped American foreign policy for years. Combined with the Watergate scandal, it contributed to a crisis of confidence that defined American public life throughout the 1970s. The Pentagon Papers, leaked to The New York Times in 1971, had already detailed the systematic deception of the public by successive administrations. The Supreme Court ruled their publication legal.

  In 1971, the revelation of the My Lai massacre - in which a US Army unit raped and killed more than 500 Vietnamese civilians in 1968 - had deepened public revulsion. The war's human toll included not only the dead but the survivors of torture, indiscriminate bombing, and the persecution of ethnic minorities documented on all sides. The Hue massacre, in which PAVN/VC forces executed approximately 2,800 unarmed civilians, stood as one atrocity among many in a conflict marked throughout by what the source describes as "large-scale massacres by both sides."

  Le Duc Tho, who had negotiated the Paris Peace Accords alongside Henry Kissinger, was awarded the Nobel Peace Prize for that agreement - a ceasefire that collapsed within two years of being signed.
