## What happened

France fortified the remote valley of Dien Bien Phu to lure the Viet Minh into a set-piece battle. Instead, General Vo Nguyen Giap's forces hauled dismantled artillery over the mountains by hand and bicycle — a documented feat — and ringed the basin.

From March 13, 1954, the strongpoints were crushed one by one and the airstrip lifeline was cut. The garrison surrendered on May 7, 1954; common accounts put the prisoners at over 11,000.

## Background

The battle came after eight years of the First Indochina War. The Geneva conference on Indochina opened the very next day, May 8.

## Consequences

France quit Indochina. The Geneva Accords of July 1954 divided Vietnam at the 17th parallel pending elections that never came — the seed of the next war. The battle became a worldwide symbol of decolonization.
