In plain words
The USA had bombers, helicopters and the richest army in history. Its enemy had sandals, bicycles and tunnels. The war showed that firepower cannot win when you cannot find the enemy, and cannot tell him from the people you came to protect.
9 things to know
- The Viet Cong fought a guerrilla war. They avoided big battles, and attacked by ambush and with booby traps, then disappeared.
- They wore no uniforms, and could not be told apart from ordinary villagers. They hid in a vast network of tunnels.
- They relied on the support of the peasants for food, shelter and information. Supplies and soldiers came from the North along the Ho Chi Minh Trail, a web of jungle paths through neighbouring countries.
- They were determined to fight for as long as it took, whatever their losses.
- American tactics. Bombing: from 1965 the USA bombed North Vietnam and the supply routes heavily. It damaged the North, but did not stop the flow of supplies.
- Search and destroy: troops were flown by helicopter to villages to find and kill Viet Cong. Villages were often burned, and civilians were killed.
- Chemical weapons: Agent Orange was sprayed to strip the leaves from the jungle. Napalm, a burning jelly, was dropped on suspected enemy positions, and it burned civilians too.
- These tactics killed many civilians and turned the peasants against the Americans. In 1968 American soldiers killed several hundred unarmed villagers at My Lai.
- In January 1968 the communists launched the Tet Offensive, attacking more than a hundred towns and cities at once. They were beaten back with heavy losses. But Americans had been told that the war was nearly won, and Tet showed that it was not.
Worked example
Explain why American tactics failed to defeat the Viet Cong. This is a 6-mark question.
- The enemy could not be found: guerrillas with no uniforms hid among villagers and in tunnels, so search and destroy killed many civilians and few fighters.
- Bombing did not work: the North had little industry to destroy, and supplies kept coming down the Ho Chi Minh Trail.
- The tactics lost the people: burned villages, napalm and Agent Orange drove the peasants to support the Viet Cong.
Tips and tricks
- Match each side's tactics to its strengths. The USA had technology and firepower. The Viet Cong had local support, patience and knowledge of the land.
- Tet was a military defeat for the communists and a political victory. That contrast is the point to make.
