Key topic 1 · The struggle against France for independence, 1945–54

What a Grade 9 answer knows here. Ho Chi Minh's 1945 declaration of independence quotes the American Declaration of Independence, and the USA financed about 80% of the French war by 1954. The conflict's origin is a decolonisation war that the Cold War reclassified.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

2 September 1945 — Ho Chi Minh declares independence, quoting the American Declaration of Independence.: It records what the Vietminh expected of the United States in 1945, which is the baseline against which everything later is measured. (The origins of the First Indochina War and the aims of the Vietminh)
November–December 1946 — The French bombardment of Haiphong; fighting begins in Hanoi.: It dates the start of the First Indochina War and shows that negotiation had been attempted and had failed. (The origins of the First Indochina War and the aims of the Vietminh)
November 1953 — French forces occupy the valley of Dien Bien Phu to draw the Vietminh into battle.: It is the decision the whole strand turns on, and it rested on an assumption about artillery that proved false. (Giap's tactics and the French defeat at Dien Bien Phu)
March 1954 — Vietminh artillery opens fire and closes the airstrip within days.: It converts a base supplied by air into a besieged one, which is the moment the plan fails rather than the moment the garrison falls. (Giap's tactics and the French defeat at Dien Bien Phu)

The people to place

Ho Chi Minh — Led the Vietminh and declared Vietnamese independence in September 1945. (The origins of the First Indochina War and the aims of the Vietminh)
Vo Nguyen Giap — Vietminh military commander from 1944; directed the war against France and later against the United States. (The origins of the First Indochina War and the aims of the Vietminh)
Henri Navarre — French commander in Indochina; approved the plan to fortify the valley. (Giap's tactics and the French defeat at Dien Bien Phu)
Pierre Mendès France — Became French Prime Minister in June 1954 committed to settling the war within thirty days. (Giap's tactics and the French defeat at Dien Bien Phu)

What students say — and what is actually the case

“The Vietnam War began with American intervention in the 1960s.” — Fighting began in December 1946 against France, and the United States was meeting most of the cost of that war by 1954. American combat troops arrived in 1965, nineteen years after the war started. (The origins of the First Indochina War and the aims of the Vietminh)
“The Vietminh won at Dien Bien Phu by guerrilla tactics.” — It was a conventional siege with massed artillery, trench approaches and a fifty-six-day investment. Giap fought exactly the set-piece battle the French had wanted, and won it. (Giap's tactics and the French defeat at Dien Bien Phu)
