After a force of 60,000 Viet Minh with heavy artillery had surrounded 16,000 French troops, news of Dien Bien Phu's impending fall reaches Washington.
French General Henri Navarre had positioned his forces 200 miles behind enemy lines in a remote area adjacent to the Laotian border. He hoped to draw the communists into a set-piece battle in which he supposed superior French firepower would prevail. He underestimated the enemy. Viet Minh General Vo Nguyen Giap entrenched artillery in the surrounding mountains and massed five divisions around the French positions. The battle, which far exceeded the size and scope of anything to date in the war between the French and the Viet Minh, began with a massive Viet Minh artillery barrage and was followed by an infantry assault.
Secretary of State John Foster Dulles and other members of the Eisenhower administration were stunned at the turn of events and discussions were held to decide on a course of action. Chairman of the Joint Chiefs of Staff Admiral Arthur Radford proposed the use of nuclear strikes against the Viet Minh. Other options included massive conventional air strikes, paratrooper drops, and the mining of Haiphong Harbor. In the end, President Eisenhower decided that the situation was too far gone and ordered no action to be taken to aid the French.
Fierce fighting continued at Dien Bien Phu until May 7, 1954, when the Viet Minh overran the last French positions. The shock at the fall of Dien Bien Phu led France, already plagued by public opposition to the war, to agree to grant independence to Vietnam at the Geneva Conference in 1954.
