Siege of Dien Bien Phu
Establishes a garrison in Dien Bien Phu to bring out the forces of General Giap
The Battle of Dien Bien Phu was the decisive confrontation of the First Indochina War. French forces established a fortified base in the remote valley, expecting to draw the Viet Minh into a battle in which French artillery and air power could dominate. Instead, General Vo Nguyen Giap's forces surrounded the position, brought heavy artillery into the surrounding heights and progressively reduced the French strongpoints.
The fall of the garrison in May 1954 transformed the diplomatic situation. The defeat accelerated negotiations at Geneva and marked the end of France's attempt to restore colonial control across Indochina.
