Vietnam War
Vietnam War, (1954–75), a protracted conflict that pitted the communist government of North Vietnam and its allies in South Vietnam, known as the Viet Cong, against the government of South Vietnam and its principal ally, the United States. Called the “American War” in Vietnam (or, in full, the “War Against the Americans to Save the Nation”), the war was also part of a larger regional conflict (see Indochina wars) and a manifestation of the Cold War between the United States and the Soviet Union and their respective allies.
At the heart of the conflict was the desire of North Vietnam, which had defeated the French colonial administration of Vietnam in 1954, to unify the entire country under a single communist regime modeled after those of the Soviet Union and China. The South Vietnamese government, on the other hand, fought to preserve a Vietnam more closely aligned with the West. U.S. military advisers, present in small numbers throughout the 1950s, were introduced on a large scale beginning in 1961, and active combat units were introduced in 1965. By 1969 more than 500,000 U.S. military personnel were stationed in Vietnam. Meanwhile, the Soviet Union and China poured weapons, supplies, and advisers into the North, which in turn provided support, political direction, and regular combat troops for the campaign in the South. The costs and casualties of the growing war proved too much for the United States to bear, and U.S. combat units were withdrawn by 1973. In 1975 South Vietnam fell to a full-scale invasion by the North.
The human costs of the long conflict were harsh for all involved. Not until 1995 did Vietnam release its official estimate of war dead: as many as 2 million civilians on both sides and some 1.1 million North Vietnamese and Viet Cong fighters. The U.S. military has estimated that between 200,000 and 250,000 South Vietnamese soldiers died in the war. In 1982 the Vietnam Veterans Memorial was dedicated in Washington, D.C., inscribed with the names of 57,939 members of U.S. armed forces who had died or were missing as a result of the war. Over the following years, additions to the list have brought the total past 58,200. (At least 100 names on the memorial are those of servicemen who were actually Canadian citizens.) Among other countries that fought for South Vietnam on a smaller scale, South Korea suffered more than 4,000 dead, Thailand about 350, Australia more than 500, and New Zealand some three dozen.
Vietnam emerged from the war as a potent military power within Southeast Asia, but its agriculture, business, and industry were disrupted, large parts of its countryside were scarred by bombs and defoliation and laced with land mines, and its cities and towns were heavily damaged. A mass exodus in 1975 of people loyal to the South Vietnamese cause was followed by another wave in 1978 of “boat people,” refugees fleeing the economic restructuring imposed by the communist regime. Meanwhile, the United States, its military demoralized and its civilian electorate deeply divided, began a process of coming to terms with defeat in what had been its longest and most controversial war. The two countries finally resumed formal diplomatic relations in 1995.

French Rule Ended, Vietnam Divided
The Vietnam War had its origins in the broader Indochina wars of the 1940s and ’50s, when nationalist groups such as Ho Chi Minh’s Viet Minh, inspired by Chinese and Soviet communism, fought the colonial rule first of Japan and then of France. The French Indochina War broke out in 1946 and went on for eight years, with France’s war effort largely funded and supplied by the United States. Finally, with their shattering defeat by the Viet Minh at the Battle of Dien Bien Phu in May 1954, the French came to the end of their rule in Indochina. The battle prodded negotiators at the Geneva Conference to produce the final Geneva Accords in July 1954. The accords established the 17th parallel (latitude 17° N) as a temporary demarcation line separating the military forces of the French and the Viet Minh. North of the line was the Democratic Republic of Vietnam, or North Vietnam, which had waged a successful eight-year struggle against the French. The North was under the full control of the Worker’s Party, or Vietnamese Communist Party, led by Ho Chi Minh; its capital was Hanoi. In the South the French transferred most of their authority to the State of Vietnam, which had its capital at Saigon and was nominally under the authority of the former Vietnamese emperor, Bao Dai. Within 300 days of the signing of the accords, a demilitarized zone, or DMZ, was to be created by mutual withdrawal of forces north and south of the 17th parallel, and the transfer of any civilians who wished to leave either side was to be completed. Nationwide elections to decide the future of Vietnam, North and South, were to be held in 1956.
Accepting the de facto partition of Vietnam as unavoidable but still pledging to halt the spread of communism in Asia, U.S. Pres. Dwight D. Eisenhower began a crash program of assistance to the State of Vietnam—or South Vietnam, as it was invariably called. The Saigon Military Mission, a covert operation to conduct psychological warfare and paramilitary activities in South Vietnam, was launched on June 1, 1954, under the command of U.S. Air Force Col. Edward Lansdale. At the same time, Viet Minh leaders, confidently expecting political disarray and unrest in the South, retained many of their political operatives and propagandists below the 17th parallel even as they withdrew their military forces to the North. Ngo Dinh Diem, the newly installed premier of South Vietnam, thus faced opposition not only from the communist regime in the North but also from the Viet Minh’s stay-behind political agents, armed religious sects in the South, and even subversive elements in his own army. Yet Diem had the full support of U.S. military advisers, who trained and reequipped his army along American lines and foiled coup plots by dissident officers. Operatives of the U.S. Central Intelligence Agency (CIA) bought off or intimidated Diem’s domestic opposition, and U.S. aid agencies helped him to keep his economy afloat and to resettle some 900,000 refugees who had fled the communist North.
By late 1955 Diem had consolidated his power in the South, defeating the remaining sect forces and arresting communist operatives who had surfaced in considerable numbers to prepare for the anticipated elections. Publicly opposed to the elections, Diem called for a referendum only in the South, and in October 1955 he declared himself president of the Republic of Vietnam. The North, not ready to start a new war and unable to induce its Chinese or Russian allies to act, could do little.
The Diem Regime And The Viet Cong
Leaders in the U.S. capital, Washington, D.C., were surprised and delighted by Diem’s success. American military and economic aid continued to pour into South Vietnam while American military and police advisers helped train and equip Diem’s army and security forces. Beneath the outward success of the Diem regime, however, lay fatal problems. Diem was a poor administrator who refused to delegate authority, and he was pathologically suspicious of anyone who was not a member of his family. His brother and close confidant, Ngo Dinh Nhu, controlled an extensive system of extortion, payoffs, and influence peddling through a secret network called the Can Lao, which had clandestine members in all government bureaus and military units as well as schools, newspapers, and businesses. In the countryside, ambitious programs of social and economic reform had been allowed to languish while many local officials and police engaged in extortion, bribery, and theft of government property. That many of these officials were, like Diem himself, northerners and Roman Catholics further alienated them from the local people.
Diem’s unexpected offensive against communist political organizers and propagandists in the countryside in 1955 had resulted in the arrest of thousands and in the temporary disorganization of the communists’ infrastructure. By 1957, however, the communists, now called the Viet Cong (VC), had begun a program of terrorism and assassination against government officials and functionaries. The Viet Cong’s ranks were soon swelled by many noncommunist Vietnamese who had been alienated by the corruption and intimidation of local officials. Beginning in the spring of 1959, armed bands of Viet Cong were occasionally engaging units of the South Vietnamese army in regular firefights. By that time the Central Committee of the Vietnamese Communist Party, meeting in Hanoi, had endorsed a resolution calling for the use of armed force to overthrow the Diem government. Southerners specially trained in the North as insurgents were infiltrated back into the South along with arms and equipment. A new war had begun.
Despite its American training and weapons, the Army of the Republic of Vietnam, usually called the ARVN, was in many ways ill-adapted to meet the insurgency of the Viet Cong. Higher-ranking officers, appointed on the basis of their family connections and political reliability, were often apathetic, incompetent, or corrupt—and sometimes all three. The higher ranks of the army were also thoroughly penetrated by Viet Cong agents, who held positions varying from drivers, clerks, and radio operators to senior headquarters officers. With its heavy American-style equipment, the ARVN was principally a road-bound force not well configured to pursuing VC units in swamps or jungles. U.S. military advisers responsible for helping to develop and improve the force usually lacked knowledge of the Vietnamese language, and in any case they routinely spent less than 12 months in the country.
At the end of 1960 the communists in the South announced the formation of the National Liberation Front (NLF), which was designed to serve as the political arm of the Viet Cong and also as a broad-based organization for all those who desired an end to the Diem regime. The Front’s regular army, usually referred to as the “main force” by the Americans, was much smaller than Diem’s army, but it was only one component of the Viet Cong’s so-called People’s Liberation Armed Forces (PLAF). At the base of the PLAF were village guerrilla units, made up of part-time combatants who lived at home and worked at their regular occupations during the day. Their function was to persuade or intimidate their neighbours into supporting the NLF, to protect its political apparatus, and to harass the government, police, and security forces with booby traps, raids, kidnappings, and murders. The guerrilla forces also served as a recruiting agency and source of manpower for the other echelons of the PLAF. Above the guerrillas were the local or regional forces, full-time soldiers organized in platoon- or company-sized units who operated within the bounds of a province or region. As members of the guerrilla militia gained experience, they might be upgraded to the regional or main forces. These forces were better-equipped and acted as full-time soldiers. Based in remote jungles, swamps, or mountainous areas, they could operate throughout a province (in the case of regional forces) or even the country (in the case of the main force). When necessary, the full-time forces might also reinforce a guerrilla unit or several units for some special operation.
The U.S. Role Grows
To the new administration of U.S. Pres. John F. Kennedy, who took office in 1961, Vietnam represented both a challenge and an opportunity. The Viet Cong’s armed struggle against Diem seemed to be a prime example of the new Chinese and Soviet strategy of encouraging and aiding “wars of national liberation” in newly independent nations of Asia and Africa—in other words, helping communist-led insurgencies to subvert and overthrow the shaky new governments of emerging nations. Kennedy and some of his close advisers believed that Vietnam presented an opportunity to test the United States’ ability to conduct a “counterinsurgency” against communist subversion and guerrilla warfare. Kennedy accepted without serious question the so-called domino theory, which held that the fates of all Southeast Asian countries were closely linked and that a communist success in one must necessarily lead to the fatal weakening of the others. A successful effort in Vietnam—in Kennedy’s words, “the cornerstone of the free world in Southeast Asia”—would provide to both allies and adversaries evidence of U.S. determination to meet the challenge of communist expansion in the Third World.
Though never doubting Vietnam’s importance, the new president was obliged, during much of his first year in office, to deal with far more pressing issues—the construction of the Berlin Wall, conflicts between the Laotian government and the communist-led Pathet Lao, and the humiliating failure of the Bay of Pigs invasion of Cuba. Because of these other, more widely known crises, it seemed to some of Kennedy’s advisers all the more important to score some sort of success in Vietnam. Success seemed urgently needed as membership in the NLF continued to climb, military setbacks to the ARVN continued, and the rate of infiltration from the North increased. U.S. intelligence estimated that in 1960 about 4,000 communist cadres infiltrated from the North; by 1962 the total had risen to some 12,900. Most of these men were natives of South Vietnam who had been regrouped to the North after Geneva. More than half were Communist Party members. Hardened and experienced leaders, they provided a framework around which the PLAF could be organized. To arm and equip their growing forces in the South, Hanoi leaders sent crew-served weapons and ammunition in steel-hulled motor junks down the coast of Vietnam and also through Laos via a network of tracks known as the Ho Chi Minh Trail. Most of the firearms for PLAF soldiers actually came from the United States: large quantities of American rifles, carbines, machine guns, and mortars were captured from Saigon’s armed forces or simply sold to the Viet Cong by Diem’s corrupt officers and functionaries.
Many of the South’s problems could be attributed to the continuing incompetence, rigidity, and corruption of the Diem regime, but the South Vietnamese president had few American critics in Saigon or Washington. Instead, the U.S. administration made great efforts to reassure Diem of its support, dispatching Vice Pres. Lyndon B. Johnson to Saigon in May 1961 and boosting economic and military aid.
As the situation continued to deteriorate, Kennedy sent two key advisers, economist Walt W. Rostow and former army chief of staff Maxwell Taylor, to Vietnam in the fall of 1961 to assess conditions. The two concluded that the South Vietnamese government was losing the war with the Viet Cong and had neither the will nor the ability to turn the tide on its own. They recommended a greatly expanded program of military assistance, including such items as helicopters and armoured personnel carriers, and an ambitious plan to place American advisers and technical experts at all levels and in all agencies of the Vietnamese government and military. They also recommended the introduction of a limited number of U.S. combat troops, a measure the Joint Chiefs of Staff had been urging as well.
Well aware of the domestic political consequences of “losing” another country to the communists, Kennedy could see no viable exit from Vietnam, but he also was reluctant to commit combat troops to a war in Southeast Asia. Instead, the administration proceeded with vigour and enthusiasm to carry out the expansive program of aid and guidance proposed in the Rostow-Taylor report. A new four-star general’s position—commander, U.S. Military Assistance Command Vietnam (USMACV)—was established in Saigon to guide the military assistance effort. The number of U.S. military personnel in Vietnam, less than 800 throughout the 1950s, rose to about 9,000 by the middle of 1962.
The Conflict Deepens
Meanwhile, the Viet Cong learned to cope with the ARVN’s new array of American weapons. Helicopters proved vulnerable to small-arms fire, while armoured personnel carriers could be stopped or disoriented if their exposed drivers or machine gunners were hit. The communists’ survival of many military encounters was helped by the fact that the leadership of the South Vietnamese army was as incompetent, faction-ridden, and poorly trained as it had been in the 1950s. In January 1963 a Viet Cong battalion near the village of Ap Bac in the Mekong delta, south of Saigon, though surrounded and outnumbered by ARVN forces, successfully fought its way out of its encirclement, destroying five helicopters and killing about 80 South Vietnamese soldiers and three American advisers. By now some aggressive American newsmen were beginning to report on serious deficiencies in the U.S. advisory and support programs in Vietnam (see Sidebar: The Vietnam War and the Media), and some advisers at lower levels were beginning to agree with them, but there was also a large and powerful bureaucracy in Saigon that had a deep stake in ensuring that U.S. programs appeared successful. The USMACV commander Paul Harkins and U.S. Ambassador Frederick Nolting in particular continued to assure Washington that all was going well.
By the summer of 1963, however, there were growing doubts about the ability of the Diem government to prosecute the war. The behaviour of the Ngo family, always odd, had now become bizarre. Diem’s brother Nhu was known to smoke opium daily and was suspected by U.S. intelligence of secretly negotiating with the North. Nhu’s wife, known to the world as Madame Nhu, wielded enormous influence, which she used to promote Roman Catholic social causes and ridicule the country’s Buddhist majority. In May 1963 the Ngos became embroiled in a fatal quarrel with the Buddhist leadership. Strikes and demonstrations by Buddhists in Saigon and Hue were met with violence by the army and Nhu’s security forces and resulted in numerous arrests. The following month a Buddhist monk, Thich Quang Duc, publicly doused himself with gasoline and set himself ablaze as a protest against Diem’s repression. Sensational photographs of that event were on the front pages of major American newspapers the following morning.
By now many students and members of the professional classes in South Vietnamese cities had joined the Buddhists. After a series of brutal raids by government forces on Buddhist pagodas in August, a group of South Vietnamese generals secretly approached the U.S. government to determine how Washington might react to a coup to remove Diem. The U.S. reply was far from discouraging, but it was not until November, after further deterioration in Diem’s relations with Washington, that the generals felt ready to move. On November 1, ARVN units seized control of Saigon, disarmed Nhu’s security forces, and occupied the presidential palace. The American attitude was officially neutral, but the U.S. embassy maintained contact with the dissident generals while making no move to aid the Ngos, who were captured and murdered by the army.
Diem’s death was followed by Kennedy’s less than three weeks later. With respect to Vietnam, the assassinated president left his successor, Lyndon B. Johnson, a legacy of indecision, half-measures, and gradually increasing involvement. Kennedy had relished Cold War challenges; Johnson did not. A veteran politician and one of the ablest men ever to serve in the U.S. Senate, he had an ambitious domestic legislative agenda that he was determined to fight through Congress. Foreign policy crises would be at best a distraction and at worst a threat to his domestic reforms. Yet Johnson, like Kennedy, was also well aware of the high political costs of “losing” another country to communism. He shared the view of most of his advisers, many of them holdovers from the Kennedy administration, that Vietnam was also a key test of U.S. credibility and ability to keep its commitments to its allies. Consequently, Johnson was determined to do everything necessary to carry on the American commitment to South Vietnam. He replaced Harkins with Gen. William Westmoreland, a former superintendent of the U.S. Military Academy at West Point, and increased the number of U.S. military personnel still further—from 16,000 at the time of Kennedy’s death in November 1963 to 23,000 by the end of 1964.
The Gulf Of Tonkin
While Kennedy had at least the comforting illusion of progress in Vietnam (manufactured by Harkins and Diem), Johnson faced a starker picture of confusion, disunity, and muddle in Saigon and of a rapidly growing Viet Cong in the countryside. Those who had expected that the removal of the unpopular Ngos would lead to unity and a more vigorous prosecution of the war were swiftly disillusioned. A short-lived military junta was followed by a shaky dictatorship under Gen. Nguyen Khanh in January 1964.
In Hanoi, communist leaders, believing that victory was near, decided to make a major military commitment to winning the South. Troops and then entire units of the North Vietnamese Army (NVA) were sent south through Laos along the Ho Chi Minh Trail, which was by that time becoming a network of modern roads capable of handling truck traffic. Chinese communist leader Mao Zedong strongly supported the North Vietnamese offensive and promised to supply weapons and technical and logistical personnel. The Soviets, though now openly hostile to China, also decided to send aid to the North.
With the South Vietnamese government in disarray, striking a blow against the North seemed to the Americans to be the only option. U.S. advisers were already working with the South Vietnamese to carry out small maritime raids and parachute drops of agents, saboteurs, and commandos into North Vietnam. These achieved mixed success and in any case were too feeble to have any real impact. By the summer of 1964 the Pentagon had developed a plan for air strikes against selected targets in North Vietnam designed to inflict pain on the North and perhaps retard its support of the war in the South. To make clear the U.S. commitment to South Vietnam, some of Johnson’s advisers urged him to seek a congressional resolution granting him broad authority to take action to safeguard U.S. interests in Southeast Asia. Johnson, however, preferred to shelve the controversial issue of Vietnam until after the November election.
An unexpected development in August 1964 altered that timetable. On August 2 the destroyer USS Maddox was attacked by North Vietnamese torpedo boats while on electronic surveillance patrol in the Gulf of Tonkin. The preceding day, patrol boats of the South Vietnamese navy had carried out clandestine raids on the islands of Hon Me and Hon Nieu just off the coast of North Vietnam, and the North Vietnamese may have assumed that the Maddox was involved. In any case, the U.S. destroyer suffered no damage, and the North Vietnamese boats were driven off by gunfire from the Maddox and from aircraft based on a nearby carrier.
President Johnson reacted to news of the attack by announcing that the U.S. Navy would continue patrols in the gulf and by sending a second destroyer, the Turner Joy, to join the Maddox. On the night of August 4 the two ships reported a second attack by torpedo boats. Although the captain of the Maddox soon cautioned that evidence for the second incident was inconclusive, Johnson and his advisers chose to believe those who insisted that a second attack had indeed taken place. The president ordered retaliatory air strikes against North Vietnamese naval bases, and he requested congressional support for a broad resolution authorizing him to take whatever action he deemed necessary to deal with future threats to U.S. forces or U.S. allies in Southeast Asia. The measure, soon dubbed the Gulf of Tonkin Resolution, passed the Senate and House overwhelmingly on August 7. Few who voted for the resolution were aware of the doubts concerning the second attack, and even fewer knew of the connection between the North Vietnamese attacks and U.S.-sponsored raids in the North or that the Maddox was on an intelligence mission. Although what many came to see as Johnson’s deceptions would cause problems later, the immediate result of the president’s actions was to remove Vietnam as an issue from the election campaign. In November Johnson was reelected by a landslide.
The United States Enters The War
Between the Gulf of Tonkin Resolution and the U.S. presidential election in November 1964, the situation in Vietnam had changed for the worse. Beginning in September, the Khanh government was succeeded by a bewildering array of cliques and coalitions, some of which stayed in power less than a month. In the countryside even the best ARVN units seemed incapable of defeating the main forces of the Viet Cong. The communists were now deliberately targeting U.S. military personnel and bases, beginning with a mortar attack on the U.S. air base at Bien Hoa near Saigon in November.
Many of Johnson’s advisers now began to argue for some sort of retaliation against the North. Air attacks against North Vietnam, they argued, would boost the morale of the shaky South Vietnamese and reassure them of continuing American commitment. They would also make Hanoi “pay a price” for its war against Saigon, and they might actually reduce the ability of the North to supply men and matériel for the military effort in the South. Except for Undersecretary of State George Ball, all the president’s civilian aides and principal military advisers believed in the efficacy of a bombing campaign; they differed only as to how it should be conducted. The military favoured a short and sharp campaign intended to cripple the North’s war-making capabilities. On the other hand, National Security Adviser McGeorge Bundy and Assistant Secretary of Defense John McNaughton argued for a series of graduated air attacks that would become progressively more damaging until the North Vietnamese decided that the cost of waging war in the South was too high. Within the administration, both Ball and Vice Pres. Hubert H. Humphrey warned the president that a major bombing campaign would likely lead only to further American commitment and political problems at home. But Johnson was more concerned with the immediate need to take action in order to halt the slide in Saigon. In mid-February, without public announcement, the United States began a campaign of sustained air strikes against the North that were code-named Rolling Thunder.
The bombing campaign followed the graduated path outlined by Bundy but was steadily expanded to include more targets and more frequent attacks. It was closely directed from the White House in order to avoid provoking the Chinese or Soviets through such actions as attacking ports where Soviet ships might be docked or hitting targets near the Chinese border. Yet it was soon apparent that the bombing would have little direct impact on the struggle in South Vietnam, where the communists appeared to be gaining ground inexorably. By mid-March Westmoreland and the Joint Chiefs of Staff were advising the White House that the United States would have to commit its own troops for combat if it wished to forestall a communist victory. Unhappy memories of the Korean War, where U.S. troops had been bogged down in costly indecisive fighting for three years, had made Johnson and his predecessors reluctant to send soldiers to fight in Asia, but the choice now confronting the president appeared to be between committing troops or enduring outright defeat.
By June 1965 Westmoreland was predicting the likely collapse of the South Vietnamese army, and he recommended the rapid dispatch of U.S. troops to undertake offensive missions against the Viet Cong and North Vietnamese anywhere in South Vietnam. Secretary of Defense Robert S. McNamara, on a mission to Vietnam in early July, confirmed the need for additional forces. In late July Johnson took the final steps that would commit the United States to full-scale war in Vietnam: he authorized the dispatch of 100,000 troops immediately and an additional 100,000 in 1966. The president publicly announced his decisions at a news conference at the end of July. There was no declaration of war—not even an address to Congress—and no attempt to put the country on a war footing economically. The National Guard and military reserves were not called to active service, even though such a measure had long been part of the military’s mobilization plans.
Firepower Comes To Naught
Although Johnson and his advisers had painstakingly examined the question of committing military forces to Vietnam—how many should be sent and when—they had given little thought to the question of what the troops might do once they arrived. In contrast to the tightly controlled air war in the North, conduct of the ground war in the South was largely left to the leadership of General Westmoreland. Westmoreland commanded all U.S. operations in the South, but he was reluctant to press for a unified U.S. and South Vietnamese command despite the questionable capabilities of many South Vietnamese generals. Instead, the two allies depended on “coordination” and a continuation of the existing advisory relationship, with every South Vietnamese army unit larger than a company having its complement of U.S. advisers. At the top of the hierarchy, Westmoreland himself served as senior adviser to the chief of the Vietnamese Joint General Staff, Gen. Cao Van Vien. The chronic political instability in Saigon seemed finally to have abated with the installation in February 1965 of a government headed by the army general Nguyen Van Thieu as head of state and air force general Nguyen Cao Ky as prime minister. This arrangement, backed by most of the top military commanders, lasted until 1968, when Ky was eased out of power, leaving Thieu in sole control.
Whatever the status of the South Vietnamese forces, they were clearly relegated to a secondary role as U.S. troops and equipment poured into the country. To support these forces, the Americans constructed an enormous logistical infrastructure that included four new jet-capable air bases with 10,000-foot (3,000-metre) runways, six new deepwater ports, 75 tactical air bases, 26 hospitals, and more than 10,000,000 square feet (900,000 square metres) of warehousing. By the fall of 1965, U.S. Marines and soldiers had clashed with NVA and VC main-force troops in bloody battles on Cape Ba Lang An (also called the Batangan Peninsula), southeast of Da Nang, and in the Ia Drang valley in the central highlands. The U.S. forces employed their full panoply of firepower, including air strikes, artillery, armed helicopters, and even B-52 bombers, to inflict enormous losses on the enemy. Yet the communists believed they had more than held their own in these battles, and they were encouraged by the fact that they could easily reoccupy any areas they might have lost once the Americans pulled out.
Westmoreland’s basic assumption was that U.S. forces, with their enormous and superior firepower, could best be employed in fighting the enemy’s strongest units in the jungles and mountains, away from heavily populated areas. Behind this “shield” provided by the Americans, the South Vietnamese army and security forces could take on local Viet Cong elements and proceed with the job of reasserting government control in the countryside. Meanwhile, the regular forces of the Viet Cong and the NVA would continue to suffer enormous casualties at the hands of massive U.S. firepower. Eventually, went the argument, the communists would reach the point where they would no longer be able to replace their losses on the battlefield. Having been ground down on the battlefield, they would presumably agree to a favourable peace settlement.
That point seemed very distant to most Americans as the war continued into 1966 and 1967. Washington declared that the war was being won, but American casualties continued to mount, and much of what the public could see of the war on television appeared confusing if not futile. Because Westmoreland’s strategy was based on attrition, one of the ways to measure progress was to track the number of enemy killed. The resultant “body count,” which was supposed to be carried out by troops during or immediately after combat, soon became notorious for inaccuracy and for the tendency of U.S. commanders to exaggerate the figures. A Program for the Pacification and Long-Term Development of Vietnam (PROVN), a study commissioned by U.S. Army Chief of Staff Harold K. Johnson and published in 1966, raised serious questions about Westmoreland’s approach. It proposed that U.S. efforts should be concentrated on providing security and stability for the rural population in South Vietnam and suggested that attrition would not work as an effective counterinsurgency strategy. At the time of its publication, PROVN was largely dismissed by military commanders, and the continued emphasis on overwhelming firepower and “search-and-destroy” missions amounted to an almost wholesale rejection of its recommendations.
In the provinces just north and east of Saigon, some large-scale operations such as Cedar Falls and Junction City, involving up to a thousand U.S. troops supported by hundreds of sorties by helicopters and fighter-bombers, were mounted to destroy communist base areas and supplies. Though yielding large quantities of captured weapons and supplies, they were ultimately indecisive, because the U.S. forces would invariably withdraw when they had completed their sweeps and in due course the Viet Cong and NVA would return. In order to deny the NVA and Viet Cong the use of dense forest to conceal their movements and to hide their supply lines and bases, the U.S. Air Force sprayed millions of gallons of a herbicide called Agent Orange along the Vietnamese border with Laos and Cambodia, in areas northwest of Saigon, and along major waterways. Agent Orange was effective in killing vegetation—but only at the price of causing considerable ecological damage to Vietnam and of exposing thousands of people to potentially toxic chemicals that would later cause serious and sometimes fatal health problems.
Along the DMZ separating North and South Vietnam, the Americans established a string of fortified bases extending from just north of Quang Tri on the South China Sea westward to the Laotian border. These bases were part of a system that also included electronic warning devices, minefields, and infrared detectors designed to check infiltration or outright invasion from the North. The North Vietnamese, pleased to find that the strong-point obstacle system was within range of their artillery, carried out periodic attacks by fire and ground forces against U.S. outposts at Con Thien, Gio Linh, Camp Carroll, and Khe Sanh.
These larger engagements attracted most of the public’s attention, but they were not in fact typical of the war in South Vietnam. Most “battles” of the war were sharp, very brief engagements between units of fewer than 200 men. Many of these lasted only a few hours, often only a few minutes, but nevertheless could result in heavy casualties. Overall, communist casualties far outnumbered U.S. casualties, but the North Vietnamese never came close to depleting their manpower. In any case, the communists could, when necessary, ease the pressure on themselves by withdrawing their forces to sanctuaries in nearby Laos, Cambodia, and North Vietnam. Hanoi, not Washington, largely controlled the tempo of the ground war.
Like the ground war in the South, the air campaign against the North continued to grow in scope and destructiveness but remained indecisive. By the end of 1966, the United States had dropped more bombs on North Vietnam than it had dropped on Japan during World War II and more than it had dropped during the entire Korean War. Yet the bombing seemed to have little impact on the communists’ ability to carry on the war. North Vietnam was primarily an agricultural country with few industries to destroy. Many of the necessities of Hanoi’s war effort came directly from China and the Soviet Union, which competed with each other to demonstrate support for Ho Chi Minh’s “heroic” war against U.S. imperialism. The Soviets provided an estimated 1.8 billion rubles in military and economic aid and sent 3,000 military advisers and technicians along with sophisticated weapons to the North. China spent an estimated two billion dollars in assisting Hanoi; at the height of its effort, it had more than 300,000 engineering, medical, and anti-aircraft artillery troops in the Democratic Republic of Vietnam. Even when bombing knocked out more than 80 percent of the North’s petroleum-storage facilities during the summer of 1966, the CIA reported no discernible shortages of petroleum or disruption of transportation. While the air raids continued, North Vietnam progressively strengthened its air defenses with the help of the latest radars, anti-aircraft guns, missiles, and modern jet fighters supplied by the Soviets and Chinese. By the end of 1966 the United States had already lost almost 500 aircraft and hundreds of air crewmen killed or held as prisoners of war.
Tet Brings The War Home
In Hanoi the communist leadership was also becoming impatient with the progress of the war. Although pleased with their ability to hold their own against the more-numerous and better-armed Americans and their South Vietnamese allies, they were aware that the United States showed no sign of giving up its hopes of victory and indeed had continued to pour more troops into Vietnam. In the summer of 1967 the communists decided on a bold stroke that would cripple the Saigon government and destroy once and for all American expectations of success. Their plan was to launch simultaneous military attacks at cities, towns, and military installations, combined with popular uprisings throughout the country. The “general offensive/general uprising” was scheduled to occur during the Lunar New Year festival, or Tet, early in 1968.
To distract attention from their preparations and attract U.S. forces away from the large cities, the communists launched diversionary attacks in October 1967 against the important but isolated town of Dak To in the central highlands and against Loc Ninh on the route to Saigon. Finally, beginning in late January 1968, two North Vietnamese divisions began a prolonged offensive against the Marine base at Khe Sanh, in the northwest corner of South Vietnam near the Laotian border. Like other bases along the DMZ, Khe Sanh was within range of artillery in North Vietnam, and, beginning on January 21, the North Vietnamese unleashed a heavy barrage against it. News reports repeatedly drew comparisons between Khe Sanh and the siege of the French fortress at Dien Bien Phu. Both the president and General Westmoreland were convinced that Khe Sanh was the enemy’s main objective and that signs of a communist buildup in the urban areas were merely a diversion.
Exactly the opposite was the case. On January 31, while approximately 50,000 U.S. and South Vietnamese troops were occupied in defending or supporting Khe Sanh and other DMZ bases, the communists launched an offensive throughout South Vietnam. They attacked 36 of 44 provincial capitals, 64 district capitals, five of the six major cities, and more than two dozen airfields and bases. Westmoreland’s Saigon headquarters came under attack, and a VC squad even penetrated the compound of the U.S. embassy. In Hue, the former imperial Vietnamese capital, communist troops seized control of more than half the city and held it for nearly three weeks.
Although taken by surprise, U.S. and South Vietnamese forces struck back quickly against the often poorly coordinated attacks. With the exception of Hue, the communists were unable to hold any town or base for more than a day or two, and their forces suffered extremely heavy casualties. South Vietnamese soldiers, often defending their homes and families, fought surprisingly well, and nowhere did the population rise up to support the Viet Cong. Indeed, so destructive were some communist attacks that many in the local population, while still disliking the Saigon government, became far less supportive of the Viet Cong.
U.S. and South Vietnamese troops may have recovered quickly, but that was not true of Americans at home. The Tet Offensive sent shock waves throughout the United States, startling those who had believed the White House’s claims that victory was near and convincing those with doubts that the situation was even worse than they had imagined. Television coverage of the destructive fighting in Saigon and Hue was extensive and graphic and left many with the impression that the United States and its ally were in desperate straits. Many in Washington still expected a major battle at Khe Sanh or further large communist attacks elsewhere.
As criticism of Johnson’s leadership by political leaders and the media mounted, the public was shocked to read in a New York Times headline story on March 10 that General Westmoreland had requested 206,000 additional troops for Vietnam. This news was widely interpreted as confirmation that the U.S. situation in Vietnam must be dire indeed. In fact, Westmoreland, assessing the Tet attacks as a serious defeat for the communists, wanted the additional troops to deliver a knockout blow against the weakened enemy. He had been encouraged to request the troops by the Joint Chiefs of Staff, who saw this as an opportunity finally to mobilize the reserves and reconstitute a strategic reserve for use in contingencies other than Vietnam. The president turned the request over to his new secretary of defense, Clark Clifford, who had replaced a disillusioned McNamara a few weeks before. Clifford soon decided not only that massive reinforcements were ill-advised but that the entire war effort had to be reassessed.
De-Escalation, Negotiation, And Vietnamization
With the aid of some of the president’s other advisers and elder statesmen from the Democratic Party, Clifford succeeded in persuading Johnson that the present number of U.S. troops in Vietnam (about 550,000) should constitute an upper limit and that Johnson, as chief executive, should make a dramatic gesture for peace. In a nationally televised speech on March 31, Johnson announced that he was “taking the first step to de-escalate the conflict” by halting the bombing of North Vietnam (except in the areas near the DMZ) and that the United States was prepared to send representatives to any forum to seek a negotiated end to the war. He followed this surprising declaration with news that he did not intend to seek reelection that year.
Three days later Hanoi announced that it was prepared to talk to the Americans. Discussions began in Paris on May 13 but led nowhere. Hanoi insisted that, before serious negotiations could begin, the United States would have to halt its bombing of the rest of Vietnam. Meanwhile, fighting continued at a high intensity. The communist high command determined to follow the Tet attacks with two more waves in May and August. At the same time, Westmoreland ordered his commanders to “keep maximum pressure” on the communist forces in the South, which he believed had been seriously weakened by their losses at Tet. The result was the fiercest fighting of the war. In the eight weeks following Johnson’s speech, 3,700 Americans were killed in Vietnam and 18,000 wounded. The communists were reported by Westmoreland’s headquarters as having lost about 43,000 killed. The ARVN’s losses were not recorded, but they were usually twice that of the Americans.
In October the Soviets secretly informed Washington that the North Vietnamese would be willing to halt their attacks across the DMZ and begin serious negotiation with the United States and South Vietnam if the United States halted all bombing of the North. Assured by his military advisers that such a halt would not adversely affect the military situation, Johnson announced the cessation of bombing on the last day of October. The bombing halt achieved no breakthrough but rather brought on a period of prolonged bickering between the United States and its South Vietnamese ally about the terms and procedures to govern the talks. By the time South Vietnam joined the talks, Richard M. Nixon had been elected president.
Nixon and his close adviser on foreign affairs, Henry A. Kissinger, recognized that the United States could not win a military victory in Vietnam but insisted that the war could be ended only by an “honourable” settlement that would afford South Vietnam a reasonable chance of survival. A hasty American withdrawal, they argued, would undermine U.S. credibility throughout the world. Although public opinion made it impossible to commit more troops, Nixon was still confident he could end the war with a favourable settlement. He planned to achieve this through bringing pressure to bear from the Soviets and China, both of whom were eager to improve their relations with the United States, and through the threat of massive force against North Vietnam. To signal to Hanoi that he could still inflict punishment by air, the president decided to act on the proposal of Gen. Creighton Abrams, who had succeeded Westmoreland in July 1968, that the United States bomb the secret communist base areas in Cambodia near the Vietnamese border.
When the communists launched another wave of attacks in South Vietnam in early 1969, Nixon secretly ordered the bombing to proceed. Cambodian premier Norodom Sihanouk, tired of his uninvited Vietnamese guests, had confidentially approved the attacks, and Hanoi was in no position to complain without revealing its own violation of Cambodia’s neutrality. Although elaborate measures had been taken in Washington and Saigon to ensure that the air attacks be kept completely secret, the story broke in The New York Times in May. Infuriated by this breach of security, Nixon began a series of measures to plug “leaks” of information; these became part of a system of illegal surveillance and burglary that eventually led to the Watergate scandal of 1972.
In view of the surprisingly good performance of the South Vietnamese army at Tet, and responding to growing pressure in the United States to begin a withdrawal of U.S. troops, the Nixon administration decided to accelerate a program to provide South Vietnam with the high-quality weapons and training that would enable them gradually to take over sole responsibility for fighting the ground war—a program labeled Vietnamization. In June 1969 Nixon announced the withdrawal of 25,000 U.S. troops from Vietnam. In September he announced further troop withdrawals, and by March 1970 he was announcing the phased withdrawal of 150,000 troops over the next year. Abrams protested that the still inexperienced and incompletely trained ARVN could hardly take over the job at such a rapid pace, but the withdrawals were enormously popular at home, and the White House soon found them politically indispensable.
Though popular at home, the withdrawals lowered the morale of the troops remaining in Vietnam by underlining the apparent pointlessness of the war. By 1970 signs of serious problems in morale and leadership were seemingly everywhere. These signs included increased drug abuse, more frequent and serious racial incidents, and even “fraggings,” the murder or deliberate maiming of commissioned and noncommissioned officers by their own troops with fragmentation weapons such as hand grenades. News of the My Lai Massacre, a mass murder by U.S. soldiers of several hundred civilians in Quang Ngai province in 1968, became public at the end of 1969, further undermining convictions about the righteousness of the U.S. military effort in Vietnam. From 1965 to 1973, more than 30,000 U.S. military personnel either in Vietnam or in service related to Vietnam received dishonourable discharges for desertion (though only a small number of desertions actually took place on the battlefield). Another 10,000 deserters were still at large when the United States withdrew from the war in 1973; most of these took advantage of clemency programs offered under Pres. Gerald R. Ford in 1974 and Pres. Jimmy Carter in 1977. Also during the period 1965–73, about half a million men became “draft dodgers,” illegally evading conscription into the armed forces or simply refusing to respond to their draft notices. More than 200,000 men were charged with draft evasion and more than 8,000 convicted. Of those convicted, most were either offered clemency by Ford or pardoned by Carter.
The United States Negotiates A Withdrawal
Nixon consequently refrained from striking North Vietnam, but he could not resist the opportunity to intervene in Cambodia, where a pro-Western government under Gen. Lon Nol had overthrown Sihanouk’s neutralist regime in March 1970. Since that time, the new regime had attempted to force the communists out of their border sanctuaries. The North Vietnamese easily fended off the attacks of the Cambodian army and began to arm and support the Cambodian communist movement, known as the Khmer Rouge. Eager to support Lon Nol and destroy the sanctuaries, Nixon authorized a large sweep into the border areas by a U.S. and South Vietnamese force of 20,000 men. The allies captured enormous quantities of supplies and equipment but failed to trap any large enemy forces. In the United States, news of the Cambodian incursion triggered widespread protest and demonstrations. These became even more intense after National Guard troops opened fire on a crowd of protesters at Kent State University in Ohio, killing four students and wounding several others, on May 4. At hundreds of campuses, students “went on strike.” Congress, meanwhile, repealed the Gulf of Tonkin Resolution.
By the summer of 1970 the White House was left with little more than Vietnamization and troop withdrawals as a way to end the war. Vietnamization appeared to be proceeding smoothly, and American counterinsurgency experts had moved swiftly after Tet to help the South Vietnamese government to develop programs to root out the Viet Cong’s underground government and establish control of the countryside. The Viet Cong, seriously weakened by losses in the 1968–69 offensives, now found themselves on the defensive in many areas. However, the limits of Vietnamization were soon demonstrated, when in March 1971 a large ARVN attack into Laos, code-named Lam Son 719 and designed to interdict the Ho Chi Minh Trail, ended in heavy casualties and a disorderly retreat.
In the United States, large-scale demonstrations were now less common, but disillusionment with the war was more widespread than ever. One poll claimed that 71 percent of Americans believed that the United States had “made a mistake” in sending troops to Vietnam and that 58 percent found the war “immoral.” Discontent was particularly directed toward the Selective Service System, which had long been seen as unfairly conscripting young men from racial minorities and poor backgrounds while allowing more-privileged men to defer conscription by enrolling in higher education. College deferments were limited in 1971, but by that time the military was calling up fewer conscripts each year. Nixon ended all draft calls in 1972, and in 1973 the draft was abolished in favour of an all-volunteer military.
Encouraged by their success in Laos, the Hanoi leadership launched an all-out invasion of the South on March 30, 1972, spearheaded by tanks and supported by artillery. South Vietnamese forces at first suffered staggering defeats, but Nixon, in an operation code-named Linebacker, unleashed U.S. air power against the North, mined Haiphong Harbour (the principal entry point for Soviet seaborne supplies), and ordered hundreds of U.S. aircraft into action against the invasion forces and their supply lines. By mid-June the communists’ Easter Offensive had ground to a halt.
With the failure of their offensive, Hanoi leaders were finally ready to compromise. The United States had indicated as early as 1971 that it would not insist on the withdrawal of North Vietnamese forces from the South. Now Hanoi signaled in return that it would not insist on replacing Thieu with a coalition government. On the basis of these two concessions, Kissinger and North Vietnamese emissary Le Duc Tho secretly hammered out a complicated peace accord in October 1972. The Saigon government, however, balked at a peace agreement negotiated without its participation or consent and demanded important changes in the treaty. In November (following Nixon’s reelection), Kissinger returned to Paris with some 69 suggested changes to the agreement designed to satisfy Thieu. The North Vietnamese responded with anger, then with proposed changes of their own. Nixon, exasperated with what he saw as the North’s intransigence and also anxious to persuade Thieu to cooperate, ordered B-52 bombers again to attack Hanoi. This so-called Christmas bombing was the most intense bombing campaign of the war.
After eight days the North Vietnamese agreed to return to Paris to sign an agreement essentially the same as that agreed upon in October. Thieu, reassured by a massive influx of U.S. military aid and by a combination of promises and threats from Nixon, reluctantly agreed to go along. On January 27, 1973, the Agreement on Ending the War and Restoring Peace in Viet-Nam was signed by representatives of the South Vietnamese communist forces, North Vietnam, South Vietnam, and the United States. A cease-fire would go into effect the following morning throughout North and South Vietnam, and within 60 days all U.S. forces would be withdrawn, all U.S. bases dismantled, and all prisoners of war (POWs) released. The issue of POWs would remain a controversial one for decades, despite the fact that there was no credible evidence to suggest that U.S. POWs had been kept secretly in Vietnam after the signing of the Paris accords (see Sidebar: Vietnam War POWs and MIAs). An international force would keep the peace, the South Vietnamese would have the right to determine their own future, and North Vietnamese troops could remain in the South but would not be reinforced. The 17th parallel would remain the dividing line until the country could be reunited by “peaceful means.”
The Fall Of South Vietnam
The following year saw a discernible pattern of hostilities: lower levels of combat and casualties but unimpeded warfare along the never-defined zones of control of the South Vietnamese government and the communists. Hundreds of Vietnamese continued to lose their lives each day after the fighting was supposed to have stopped. By the summer of 1974 Nixon had resigned in disgrace, Congress had cut military and economic aid to Vietnam by 30 percent, and the Lon Nol regime in Cambodia appeared close to defeat. Thieu’s government, corrupt and inefficient as ever, now faced enormous difficulties with inflation, unemployment, apathy, and an enormous desertion rate in the army. After an easy success at Phuoc Long, northeast of Saigon, in December 1974–January 1975, the Hanoi leaders believed that victory was near.
In early March
the North Vietnamese launched the first phase of what was expected to be a
two-year offensive to secure South Vietnam. As it happened, the South’s
government and army collapsed in less than two months. Thousands of ARVN troops
retreated in disorder, first from the central highlands and then from Hue and
Da Nang. Gerald R. Ford, who had succeeded Nixon as U.S. president, pleaded in
vain with Congress for additional military aid that might at least raise
Saigon’s morale. But members of Congress, like most of their constituents, were
ready to wash their hands of a long and futile war. On April 21 Thieu resigned
and flew to Taiwan. On April 30 what remained of the South Vietnamese
government surrendered unconditionally, and NVA tank columns occupied Saigon
without a struggle. The remaining Americans escaped in a series of frantic air-
and sealifts with Vietnamese friends and coworkers. A military government was
instituted, and on July 2, 1976, the country was officially united as the
Socialist Republic of Vietnam with its capital in Hanoi. Saigon was renamed Ho
Chi Minh City. The 30-year struggle for control over Vietnam was over.
