Operation Camargue was one of the largest operations by the French Far East Expeditionary Corps and Vietnamese National Army in the First Indochina War. It took place from 28 July until 10 August 1953. French armored platoons, airborne units and troops delivered by landing craft to the coast of central Annam, modern-day Vietnam, attempted to sweep forces of the communist Viet Minh from the critical Route One.

The first landings took place in the early morning on 28 July, and reached the first objectives, an inland canal, without major incident. A secondary phase of mopping-up operations began in a "labyrinth of tiny villages" where French armored forces suffered a series of ambushes. Reinforced by paratroopers, the French and their Vietnamese allies tightened a net around the defending Viet Minh, but delays in the movement of French forces left gaps through which most of the Viet Minh guerillas, and many of the arms caches the operation was expected to seize, escaped. For the French, this validated the claim that it was impossible to operate tight ensnaring operations in Vietnam's jungle, due to the slow movement of their troops, and a foreknowledge by the enemy, which was difficult to prevent. From then on, the French focused on creating strong fortified positions, against which Viet Minh General Gip could pit his forces, culminating in Operation Castor and the Battle of Dien Bien Phu.With the French forces withdrawn from the operation by the late summer of 1953, Viet Minh Regiment 95 re-infiltrated Route One and resumed ambushes of French convoys, retrieving weapons caches missed by the French forces. Regiment 95 occupied the area for the remainder of the First Indochina War and were still operating there as late as 1962 against the South Vietnamese Army during the Second Indochina, or Vietnam War.



The First Indochina War (generally known as the Indochina War in France, and as the Anti-French Resistance War in Vietnam) began in French Indochina on December 19, 1946, and lasted until July 20, 1954. Fighting between French forces and their Việt Minh opponents in the south dated from September 1945. The conflict pitted a range of forces, including the French Union's French Far East Expeditionary Corps, led by the government of France and supported by the former emperor Bảo Đại's Vietnamese National Army against the People's Army of Vietnam and Việt Minh (part of the Communist Party), led by Võ Nguyên Giáp and Hồ Chí Minh. Most of the fighting took place in Tonkin in northern Vietnam, although the conflict engulfed the entire country and also extended into the neighboring French Indochina protectorates of Laos and Cambodia.

At the Potsdam Conference in July 1945, the Combined Chiefs of Staff decided that Indochina south of latitude 16° north was to be included in the Southeast Asia Command under British Admiral Mountbatten. The Japanese forces located south of that line surrendered to him and those to the north surrendered to Generalissimo Chiang Kai-shek. In September 1945, Chinese forces entered Tonkin, and a small British task force landed at city of Saigon (Cochinchina's capital). The Chinese accepted one Vietnamese government under Hồ Chí Minh, then in power in Hanoi (Tonkin's capital). The British refused to do likewise in Saigon, and deferred to the French there from the outset, against the ostensible support of the Việt Minh authorities by American OSS representatives. On V-J Day, September 2, Hồ Chí Minh had proclaimed in Hanoi the establishment of the Democratic Republic of Vietnam (DRV). The DRV ruled as the only civil government in all of Vietnam for a period of about 20 days, after the abdication of Emperor Bảo Đại, who had governed under the Japanese rule. On 23 September 1945, with the knowledge of the British commander in Saigon, French forces overthrew the local DRV government, and declared French authority restored in Cochinchina. Guerrilla warfare began around Saigon immediately, but the French gradually retook control of the South and North of Indochina. Hồ Chí Minh agreed to negotiate the future status of Vietnam, but the talks, held in France, failed to produce a solution. After over one year of latent conflict, all-out war broke out in December 1946 between French and Việt Minh forces as Hồ Chí Minh and his government went underground. The French tried to stabilize Indochina by reorganizing it as a Federation of Associated States. In 1949, they put former Emperor Bảo Đại back in power, as the ruler of a newly established State of Vietnam.

The first few years of the war involved a low-level rural insurgency against the French. In 1949 the conflict turned into a conventional war between two armies equipped with modern weapons supplied by the United States, China and the Soviet Union. French Union forces included colonial troops from their former empire - Moroccan, Algerian, and Tunisian Arabs/Berbers; Laotian, Cambodian and Vietnamese ethnic minorities; Black Africans - and French professional troops, European volunteers, and units of the Foreign Legion. The use of metropolitan recruits was forbidden by the government to prevent the war from becoming even more unpopular at home. It was called the "dirty war" (la sale guerre) by leftists in France.The strategy of pushing the Việt Minh into attacking well-defended bases in remote parts of the country at the end of their logistical trails was validated at the Battle of Nà Sản even though the base was relatively weak because of a lack of concrete and steel. French efforts were made more difficult due to the limited usefulness of armored tanks in a jungle environment, lack of strong air forces for air cover and carpet bombing, and use of foreign recruits from other French colonies (mainly from Algeria, Morocco and even Vietnam). Võ Nguyên Giáp, however, used efficient and novel tactics of direct fire artillery, convoy ambushes and massed anti-aircraft guns to impede land and air supply deliveries together with a strategy based on recruiting a sizable regular army facilitated by wide popular support, a guerrilla warfare doctrine and instruction developed in China, and the use of simple and reliable war material provided by the Soviet Union. This combination proved fatal for the bases' defenses, culminating in a decisive French defeat at the Battle of Dien Bien Phu.At the International Geneva Conference on July 21, 1954, the new socialist French government and the Việt Minh made an agreement which effectively gave the Việt Minh control of North Vietnam above the 17th parallel. The south continued under Bảo Đại. The agreement was denounced by the State of Vietnam and by the United States. A year later, Bảo Đại would be deposed by his prime minister, Ngô Đình Diệm, creating the Republic of Vietnam (South Vietnam). Soon an insurgency, backed by the north, developed against Diệm's government. The conflict gradually escalated into the Vietnam War (1955–1975).
