Tactics and Relative Strengths of the Two Sides (AQA A-Level History): Revision Notes
Tactics and Relative Strengths of the Two Sides
Context: Escalation and early combat
Following President Johnson's decision on 28 July 1965 to expand American military involvement, the USA deployed 75,000 ground troops to Vietnam. North Vietnamese leaders interpreted this escalation as confirmation that America intended more than just defending South Vietnam, strengthening their determination to continue fighting.
The first major engagement between American and North Vietnamese forces occurred in November 1965 at the Ia Drang Valley in the Central Highlands. This conventional battle resulted in approximately 300 American casualties and 2,000-3,000 North Vietnamese dead. Both sides claimed victory: the USA pointed to the high enemy casualty figures, whilst North Vietnam highlighted their ability to hold their position.
This battle proved decisive in shaping subsequent tactics, particularly for the North Vietnamese. General Vo Nguyen Giap, commanding North Vietnamese forces, recognised that conventional warfare against the superior American military would not succeed. He therefore developed an alternative strategy emphasising guerrilla warfare.
The scale of American military involvement
The expansion of American operations between 1965 and 1968 demonstrated the massive commitment of resources:
| Year | Bomb tonnage | Ground troops |
|---|---|---|
| 1965 | 63,000 tons | 184,310 |
| 1966 | 136,000 tons | 385,300 |
| 1967 | 226,000 tons | 485,600 |
| 1968 | - | 536,000 |
The dramatic increase in both aerial bombardment and troop numbers reflected America's commitment to military victory through overwhelming force. By 1968, bomb tonnage had increased by over 350% compared to 1965, whilst ground troops nearly tripled in the same period.
The USA's strengths
Economic and logistical superiority
American forces possessed enormous economic resources, which translated into military advantages. A substantial logistical operation ensured troops received modern equipment in plentiful supply. By 1967, approximately one million tons of supplies arrived in South Vietnam monthly. Infrastructure development included constructing airfields and helicopter landing pads throughout the country.
Helicopter warfare
The helicopter represented a transformative military tool in Vietnam. It enabled rapid troop deployment directly to combat zones without the danger of ambush. Helicopters also proved essential for evacuating wounded soldiers from battlefields. As an offensive weapon, helicopters provided mobile firepower. The emphasis on speed characterised American operations, with helicopters allowing forces to respond quickly to threats across difficult terrain.
Bombing campaigns
American bombing operations commenced with Operation Rolling Thunder. The B-52 bomber served as the primary aircraft for these missions. Bombing aimed to destroy North Vietnam's economy and weaken Vietcong and North Vietnamese Army forces operating in the South. However, this objective failed.
North Vietnam's predominantly agrarian economy possessed few industrial centres. The country lacked substantial military production facilities. The tonnage of explosives dropped on Vietnam during the war exceeded that used throughout the Second World War. The US 7th Fleet controlled waters around Vietnam, providing bases for air operations.
Despite this massive effort, North Vietnam's lost resources were quickly replaced through aid from China and the USSR.
Chemical warfare
To undermine Vietcong guerrilla operations, President Kennedy approved Operation Ranch Hand in early 1962. This involved spraying chemicals to defoliate jungles, removing the cover exploited by enemy forces.
Agent Orange was a chemical containing dioxin, a toxic defoliant which destroyed vegetation and caused severe health problems including birth deformities in children exposed to it.
Another chemical weapon was napalm, a gel which spread over wide areas upon landing and ignited. Many civilians suffered burns and death from this weapon.
Pineapple bombs (anti-personnel bombs) released thousands of small pellets in explosions. These weapons killed indiscriminately, with numerous civilian casualties.
The overall effect of chemical weapons was to alienate Vietnamese peasants whose crops and livelihoods were destroyed whilst guerrilla forces continued operating. This represented a fundamental failure in winning civilian support - the very goal necessary for victory in a guerrilla war.
Search and destroy operations
Search and destroy was a strategy designed to locate and eliminate enemy forces in jungle and rural areas. American forces arrived by helicopter and raided villages suspected of sheltering Vietcong. The extreme difficulty of identifying enemy fighters meant many innocent civilians were killed. Livestock and food sources were destroyed, along with villagers' homes.
The Central Contradiction
Such tactics completely undermined efforts to win support from rural peasants, pushing them towards supporting the Vietcong. A fundamental contradiction existed between using indiscriminate violence against civilians and attempting to win those same people's loyalty.
Attrition warfare
General William Westmoreland commanded US forces in Vietnam from 1964 until 1968. He failed to understand the tactics employed by North Vietnamese forces, placing excessive faith in American military superiority and commitment to deploying increasing numbers of ground troops to overwhelm the enemy.
The basic approach Westmoreland adopted was attrition: American forces would persistently attack the enemy until victory was achieved. Success in this ground war was not measured by territorial gains but by 'body count' (the number of enemy dead). This approach suggested apparent American strength, but the two main tactics explored above reveal a different reality.
The USA's weaknesses
By 1968, American strengths were far outweighed by weaknesses. The methods used by North Vietnamese forces exacerbated these problems.
Problems with the South Vietnamese Army
America's ally, the South Vietnamese Army, remained largely uncommitted to the struggle. The army frequently avoided combat and its troops lacked adequate training as soldiers. This placed greater burden on American forces.
Media coverage and domestic opposition
American forces were weakened by widespread television and press coverage of the war. Images of South Vietnamese peasants being brutalised intensified the growing anti-war movement in the USA.
The Impact of Martin Luther King's Opposition
Civil rights campaigners such as Martin Luther King reinforced this opposition. In a speech in April 1967, King argued the war was undermining Johnson's commitment to social reform and the 'Great Society'. Black Americans were immediate victims of the failure to maintain expensive domestic reform programmes. King also questioned whether the war benefited the civil rights of South Vietnamese people. His was an influential voice, particularly as many young Black Americans were drafted into the US Army in Vietnam.
Domestic opposition to the war developed multiple strands. Some opponents were pacifists, some isolationists, others challenged America's right to determine other states' fate. Collectively the opponents increasingly divided American society, which damaged Johnson's war effort.
North Vietnam's strengths
Determination and knowledge of terrain
The most effective asset of North Vietnamese forces was the determination and resolve of their troops and their tactical ingenuity in battle. Unlike American forces, they possessed intimate knowledge of the country and its people. North Vietnam also received logistical support from China and the USSR.
Peasant support and ideology
Northern forces consisted of the Vietcong and the regular North Vietnamese Army. The Vietcong strengthened its position by recruiting among disaffected, anti-American rural peasants in South Vietnam.
The Maoist Principles of the National Liberation Front
The guiding principles of the National Liberation Front (NLF) guerrilla forces were modelled on those established by Mao Zedong in China:
- Do not destroy land or crops
- Always keep your word
- Always show the peasants respect
- Always support the peasants
These methods won support, demonstrating how ideological commitment translated into practical rules of engagement.
However, the Vietcong were also prepared to use violence against any peasants who challenged them. An element of coercion through terror operated alongside the ideological appeal.
Guerrilla tactics
To compensate for their inability to engage in conventional warfare, North Vietnamese forces adopted sophisticated guerrilla tactics to undermine American forces' resolve and morale:
- Complex tunnel systems were constructed to hide Vietcong troops underground. These elaborate networks included firing posts, meeting rooms, sleeping chambers, storage areas for weapons and food, and blast deflection walls. Airtight trapdoors and stake traps protected tunnel entrances.
- Booby traps of various kinds were deployed in dense forests. Trip wires set off grenades and mines. Small groups of troops ambushed American forces in the jungles.
These tactics proved highly effective in offsetting American technological superiority. By forcing American troops into close-quarters combat in unfamiliar terrain, guerrilla warfare neutralised many of the USA's military advantages.
The Ho Chi Minh Trail
This primary supply route proved essential to the logistical tactics deployed by the North. It passed through Cambodia and Laos into South Vietnam, serving as an important supply line for both personnel and equipment. Although it was a regular target for American attacks, it was never fully disabled.
Support from the USSR and China
Northern forces were strengthened not merely by their ideological commitment and nationalism, but also through the support they received from the USSR and China.
Military Aid from Communist Powers
In December 1964, China agreed to provide military supplies to North Vietnam. Between 1964 and 1969, China's commitment to military aid expanded substantially. In 1964, China supplied over 80,000 guns; this steadily increased to approximately 140,000 by 1989. The USSR supplied surface-to-air missiles, MiG-21 jets and artillery systems.
North Vietnam's weaknesses
Economic dependency
There existed a degree of dependency upon both the USSR and China. The North's economy could not sustain a prolonged war, even one based on guerrilla tactics.
Limited guaranteed support
There was no guaranteed support among many South Vietnamese peasants. This became apparent when the planned uprising among such people during the Tet Offensive never materialised.
Key Points to Remember:
-
The Ia Drang Valley battle (November 1965) convinced North Vietnamese commanders that conventional warfare could not succeed against American military superiority, leading to emphasis on guerrilla tactics.
-
American strengths included economic resources, helicopter mobility, massive bombing campaigns, and chemical weapons, but these failed to achieve decisive victory and often alienated Vietnamese civilians.
-
American weaknesses centred on an uncommitted South Vietnamese ally, growing domestic opposition fuelled by media coverage, and the civil rights movement's criticism of the war.
-
North Vietnamese strengths lay in troop determination, knowledge of terrain, peasant support (built through Maoist principles), sophisticated guerrilla tactics including tunnel systems, the Ho Chi Minh Trail, and military aid from China and the USSR.
-
General Westmoreland's attrition strategy and 'search and destroy' operations measured success by body count rather than territorial gains, creating a fundamental contradiction between military violence and winning civilian support.
