First Indochina War

The De Lattre Line, named after General Jean de Lattre de Tassigny, was a line of concrete fortifications, obstacles, and weapons installations constructed by the French around the Red River Delta in northern Vietnam.

Jean Joseph Marie Gabriel de Lattre de Tassigny, GCB, MC was a French military commander in World War II and the First Indochina War. He was posthumously promoted to Marshal of France.

Fortification military constructions and buildings designed for defense in warfare and military bases

A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to solidify rule in a region during peacetime. The term is derived from the Latin fortis ("strong") and facere.

Red River Delta River delta in Vietnam

The Red River Delta is the flat low-lying plain formed by the Red River and its distributaries merging with the Thái Binh River in northern Vietnam. The delta has the smallest area but highest population and population density of all regions. The region measuring some 15,000 square km is well protected by a network of dikes. It is an agriculturally rich area and densely populated. Most of the land is devoted to rice cultivation.

The French established the fortification to guard the essential lines of communication between the cities of Hanoi and Haiphong and to provide security for the densely populated and economically important Delta area against attacks by both the Việt Minh and any potential invasion from Communist China.

Hanoi Municipality in Hà Nội, Vietnam

Hanoi is Vietnam's capital and second largest city by population. The city mostly lies on the right bank of the Red River. Hanoi is 1,720 km (1,070 mi) north of Ho Chi Minh City and 105 km (65 mi) west of Haiphong.

Haiphong Municipality in Vietnam

Haiphong is a major industrial city, the second largest city in the northern part of Vietnam, and third largest city overall in Vietnam. Hai Phong is also the center of technology, economy, culture, medicine, education, science and trade in the northern coast of Vietnam.

Việt Minh national independence coalition

Việt Minh was a national independence coalition formed at Pác Bó by Hồ Chí Minh on May 19, 1941. The Việt Nam Độc Lập Đồng Minh Hội had previously formed in Nanjing, China, at some point between August 1935 and early 1936 when Vietnamese Nationalist or other Vietnamese nationalist parties formed an anti-imperialist united front. This organization soon lapsed into inactivity, only to be revived by the Indochinese Communist Party (ICP) and Hồ Chí Minh in 1941. The Việt Minh established itself as the only organized anti-French and anti-Japanese resistance group. The Việt Minh initially formed to seek independence for Vietnam from the French Empire. The United States supported France. When the Japanese occupation began, the Việt Minh opposed Japan with support from the United States and the Republic of China. After World War II, the Việt Minh opposed the re-occupation of Vietnam by France and later opposed South Vietnam and the United States in the Vietnam War. The political leader and founder of Việt Minh was Hồ Chí Minh. The military leadership was under the command of Võ Nguyên Giáp. Other founders were Lê Duẩn and Phạm Văn Đồng.

The Line was to comprise 1200 separate concrete blockhouses able to withstand 155mm artillery grouped in 250 clusters of 3-6 blockhouses for mutual fire support over a span of 235 miles (378 km). Each blockhouse was to hold a minimum of 10 men. In addition a defensive redoubt was to be constructed around a 22 miles (35 km) radius from the port of Haiphong ensuring its safety from artillery attack. All these new defensive lines were to be connected by roads capable of bearing 30-ton tanks. Construction commenced in late 1950 and was largely complete by the end of 1951. [1] :116

While the De Lattre Line provided some degree of security and formed an anchor point for French mobile operations outside the Delta, it was far from impenetrable and entire Việt Minh combat units could be easily infiltrated through the gaps between strongpoints. [2]

Following the withdrawal of the French from northern Vietnam in October 1954 the De Lattre Line was abandoned. Today the deteriorating blockhouses are either unused or used by farmers.

Blockhouse small, isolated fort in the form of a single building

In military science, a blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It usually refers to an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force and cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt.

The Battle of Cao Bằng was an ongoing campaign in northern Indochina during the First Indochina War, between the French Far East Expeditionary Corps and the Việt Minh, which began in October 1947 and culminated on September 3, 1949. Since the start of the conflict, Việt Minh troops had ambushed French convoys along the Vietnam–China border from the Gulf of Tonkin on a 147-mile route to a French garrison at Cao Bằng, known as Route Colonial 4, or RC4. Repeated ambushes led to repeated French operations of increasing strength to reopen the road, including a costly mission by the Foreign Legion in February 1948. On July 25, 1948, the Cao Bằng encampment was itself attacked and held out for three days with two companies defending against two battalions of Việt Minh. A further 28 ambushes took place in 1948.

Battle of the Day River

The Battle of the Day River took place between late May and early June 1951, around the Day River Delta in the Gulf of Tonkin. Part of the First Indochina War, the battle was the first conventional campaign of Võ Nguyên Giáp, and saw his Việt Minh People's Army of Vietnam (VPA) forces tackle the Catholic-dominated region of the Delta in order to break its resistance to Việt Minh infiltration. On the back of two defeats at similar ventures through March and April that year, Giap led three divisions in a pattern of guerrilla and diversion attacks on Ninh Bình, Nam Định, Phủ Lý and Phat Diem beginning on May 28 which saw the destruction of commando François, a naval commando. The French army, under Jean de Lattre de Tassigny, who lost his son in the first day of the battle at Ninh Bình, mobilised three mobile groups and two paratrooper battalions as well as one dinassaut, and the ebb and flow of captured and retaken positions continued until Giap's supply lines were cut around June 6. His forces, moving in large numbers and during daylight, were vulnerable to French firepower and to French ground forces supported by friendly local militia. The Việt Minh army units were forced into withdrawing between June 10 and June 18, leaving 1,000 prisoners to the French and 9,000 casualties.

War in Vietnam (1945–46) Prelude to the Indochina Wars

The War in Vietnam, codenamed Operation Masterdom by the British, and also known as Nam Bộ kháng chiến by the Vietnamese, was a post–World War II armed conflict involving a largely British-Indian and French task force and Japanese troops from the Southern Expeditionary Army Group, versus the Vietnamese communist movement, the Viet Minh, for control of the country, after the unconditional Japanese surrender.

The Battle of Nghĩa Lộ, also called Ly Thuong Kiet Campaign by Việt Minh, was fought between the French army and the Việt Minh during the First Indochina War. Both general Giap and de Lattre waited eagerly for the battle due to the postponement that occurred when Giap's attack along the Day River were driven back in June 1951. Since Giap was the one controlling the tempo of this war for months, it took a huge turn during the pause after his defeat causing his military situation to become unstable. On 3 October, the Việt Minh 312th Division launched an attack on French forces in the town of Nghĩa Lộ and its vicinity which was led by the general Giap. This attack on Nghĩa Lộ occurred 95 miles west of Hanoi and only 65 miles past that of the western de Lattre Line. This village was the upmost importance to de Lattre because it served as the capital of the T'ai natives which had very strong ties with the French. The first attacked was carried out by two regiments of the 312th Division to the surrounding posts that acted as the main defense of the town in order to maintain military control. Since de Lattre was not present at the time, General Salan took the reigns of the situation and quickly reinforced the surrounding posts with paratroopers carried by parachutes to fortify defenses. This quick strategy by General Salan was looked upon the saving grace of this battle since it repelled a secondary attack by two regiments of the 312th Division that same night. Additional reinforcements occurred during the 4th of October along with air support which led to General Giap to call off his attack which they then fled across the Red River. A year later on 17 October, the Việt Minh launched another attack on Nghĩa Lộ and succeeded in driving out the remaining French from the area.

The Battle of Nghĩa Lộ was a battle of the First Indochina War. In the fall of 1952 the French army encountered its most serious crisis since the disasters near the Chinese border at Cao Bằng, Đông Khê and RC 4 occurred in 1949 and 1950. The Battle of Nghĩa Lộ was the opening salvo in a series of offenses and counter-offenses in late 1952 during the First Indochina War. It was part of a Việt Minh offensive in the T’ai region of Tonkin in the vicinity of the Black River. The French countered with Operation Lorraine to attack Việt Minh rear supply bases in an attempt to cut off the offensive. The Việt Minh did not cease or divert the offensive to protect its supply bases. The Việt Minh continued its offensive attack against Nà Sản where there was an outpost and a short airstrip, both guarded by the French army. This series of battles lasted for three months between October 1952 and December 1952. These actions and the Việt Minh successes set the stage for the subsequent Invasion of Laos in April 1953.
