Dien Bien Phu
13 Mar–7 May 1954 — Giap’s peasant army hauls artillery up jungle mountains and destroys a French fortress of 15,000. A European empire is beaten in open battle; Geneva partitions Vietnam within weeks.
THE MOMENT IN CONTEXT
Start at Dien Bien Phu, 1954 — the marker in the far northwest — where Giap’s army, hauling dismantled artillery up jungle mountains by hand, destroys a French fortress and with it French Indochina. Geneva splits Vietnam at the 17th parallel “pending elections” that Saigon and Washington, certain Ho Chi Minh would win them, never allow. The domino theory takes over from there: if Vietnam falls, runs the logic Eisenhower states and Kennedy and Johnson inherit, all Southeast Asia follows. So American commitment ratchets — advisers under Kennedy, then after the murky Tonkin Gulf incident of August 1964, an open-ended air war (the arrow from the sea) and half a million troops by 1968, fighting an enemy supplied down the Ho Chi Minh Trail through Laos and Cambodia — the long arrow your map shows threading the border.
From Chapter 7 — Vietnam of The Cold War, 1945–1991 (AUG 1968).
