Battle of Dien Bien Phu
Decisive Viet Minh victory that ended French rule in Indochina.
The Battle of Điện Biên Phủ was a decisive engagement of the First Indochina War, fought between the French Union and the communist Viet Minh from 13 March to 7 May 1954. The Viet Minh, under General Võ Nguyên Giáp, besieged and overran a heavily fortified French camp in northwest Tonkin, leading to the surrender of the garrison. The defeat shocked France and precipitated the 1954 Geneva Accords, which temporarily divided Vietnam at the 17th parallel.

Background
By 1953, France had struggled to suppress the Viet Minh insurrection under a succession of commanders. During the 1952–1953 campaign, the Viet Minh overran large areas of Laos, advancing as far as Luang Prabang and the Plain of Jars, but withdrew when their supply lines became overextended. The French strengthened defenses in the Hanoi delta and established fortified towns such as Lai Châu, Nà Sản, and the Plain of Jars. In May 1953, Premier René Mayer appointed Henri Navarre to command French Union forces, ordering him to create conditions for an honorable political solution. According to military scholar Phillip Davidson, Navarre found no long-range plan, only reactive operations, and was shocked by the complacent attitude of his predecessor Raoul Salan and his staff, who were focused on leaving Indochina with their reputations intact rather than addressing the problems facing their successors.
Prelude
In June 1953, Major General René Cogny proposed using Điện Biên Phủ, which had a Japanese-built airstrip, as a mooring point. Cogny envisioned a lightly defended base for raids, but Navarre interpreted this as a heavily fortified hedgehog position. Navarre selected the site for the operation despite protests from every major subordinate officer, including Colonel Jean-Louis Nicot, Cogny, and Generals Jean Gilles and Jean Dechaux. Cogny warned of a risk similar to the earlier disaster at Nà Sản. Navarre rejected the criticisms and ordered the operation to begin on 20 November 1953. He had been assured by intelligence that a strong enemy force was unlikely to be involved. Navarre had considered other approaches to defending Laos—mobile warfare, a static defense line, or supplying Laotian provincial capitals by air—but deemed them unworkable. The French National Defense Committee agreed that Navarre was not responsible for defending Laos, but its decision, dated 13 November, was not delivered until 4 December, after the operation had begun.
Battle
The Viet Minh assault began on 13 March 1954 with an attack on the northeastern outpost Béatrice, held by the 3rd Battalion, 13th Foreign Legion Demi-Brigade. Viet Minh artillery, including 105 mm howitzers, 120 mm mortars, and 75 mm mountain guns, bombarded the position. A shell hit the French command post at 18:30, killing battalion commander Major Paul Pégot and most of his staff; Lieutenant Colonel Jules Gaucher, commander of the central subsector, was also killed. The Viet Minh 312th Division, with its 141st and 209th Infantry Regiments and sappers, then assaulted Béatrice, which comprised three strong points. Beatrice-3 was quickly overrun by the 209th Regiment's 130th Battalion. Beatrice-1 was mostly taken by the 141st Regiment's 428th Battalion, though defenders held out in a corner until 22:30. Roughly 350 French legionnaires were killed, wounded, or captured; about 100 escaped. The French estimated Viet Minh losses at 600 dead and 1,200 wounded, while the Viet Minh reported 193 killed and 137 wounded. The victory galvanized Viet Minh morale.
Aftermath
The destruction of the garrison cost France roughly one-tenth of its total manpower in Indochina and weakened its position and prestige, with psychological repercussions in the armed forces and political structure. Negotiations over Indochina's future had begun in April. On the morning of the surrender, Henri Navarre took a salute at a Victory in Europe Day parade in Hanoi and broadcast that Upper Laos had been saved, the Delta protected, and the garrison had fought to the bitter end; he blamed the defeat on Chinese communist supplies. Within weeks, Viet Minh units withdrew from virtually all of Laos. News of the fall reached France around 16:45, announced by Prime Minister Joseph Laniel. The Archbishop of Paris ordered a mass, radio performances were replaced by solemn music, and theatres and restaurants closed. Public opinion was shocked that a guerrilla army had defeated a major European power. Laniel resigned in June, replaced by Pierre Mendès France. A general lull followed across Indochina. In mid-June, the French high command ordered isolated positions abandoned. Groupement Mobile No. 100, including the elite UN Bataillon de Corée, was ordered to fall back from An Khe to Pleiku but was ambushed at the Battle of Mang Yang Pass, suffering heavy losses by 29 June.
