Vinh Loc Island
154-466: A cease-fire being brokered by President Lyndon Johnson. This action violated the Logan Act , banning private citizens from intruding into official government negotiations with a foreign nation, and thus constituted treason. While the discussion following splits into military and political/civil strategies, that is a Western perspective. North Vietnamese forces took a more grand strategic view than did
231-779: A centre of gravity built around gradual and small-scale erosion of US capabilities, closing the enormous technological disadvantage with surprise attacks and strategies, while building and consolidating political control over the rural areas of South Vietnam. See the protracted warfare model . Despite differences in were both sides believe their centres of gravity were, the NVA and Viet Cong would retain strategic initiative throughout this period, choosing when and were to attack, and being capable of controlling their losses quite widely. They were estimated to have initiated 90% of all contacts and engagement firefights, in which 46% of all engagements were NVA/VC ambushes against US forces. A different study by
308-507: A conventional, combined-arms conquest against the Army of the Republic of Vietnam , and taking and holding land permanently. Military developments in this period should be considered in several broad phases that do not fit neatly into a single year: Some fundamental decisions about U.S. strategy, which would last for the next several years, took place in 1965. Essentially, there were three alternatives: Even with these three approaches, there
385-549: A figurehead. COL Bùi Tín led a reconnaissance mission of specialists reporting directly to the Politburo, who said, in a 1981 interview with Stanley Karnow, that he saw the only choice was escalation including the use of conventional troops, capitalizing on the unrest and inefficiency from the series of coups in the South. The Politburo ordered infrastructure improvements to start in 1964. In February and March 1964, confirming
462-465: A graduated scale of intensity, ranging from reconnaissance, threats, cross-border operations, and limited strikes on logistical targets supporting DRV operations against South Vietnam and Laos, to strikes (if necessary) on a growing number of DRV military and economic targets. In the absence of all-out strikes by the DRV or Communist China, the measures foreseen would not include attacks on population centers or
539-604: A guerilla in Asia during the Second World War, was forced out of office on 24 February. MG Jack Singlaub, to become the third commander of SOG, argued that special operators needed to form their own identity; while today's United States Special Operations Command has components from all the services, there is a regional Special Operations Component, alongside Army, Navy, Air Force, and Marine Components, in every geographic Unified Combatant Command . Today, officers from
616-534: A land war in Asia, and that the U.S. was too concerned with Chinese intervention to use airpower outside South Vietnam. Once the elections were over, North Vietnam developed a new plan to move from the Ho Chi Minh trail in Cambodia, in central Vietnam (i.e., ARVN II Corps Tactical Zone ), with a goal of driving through to the seacoast over Highway 19 , splitting South Vietnam in half. For this large operation,
693-555: A matter of establishing a viable, sustainable political structure for South Vietnam, rather than radically improving the short-term security situation. It saw the Minh-Tho government as enjoying an initial period of popular support as it removed some of the most disliked aspects of the Diem government. During this time, the increase in VC attacks was largely coincidental; they were resulting from
770-560: A maximum effort of American power could salvage the situation. Two days later, the Minh Tho government was overthrown. Col. Don Si Nguyen brought in battalions of engineers to improve the Trail, principally in Laos, with up-to-date Soviet and Chinese construction equipment, with a goal, over several years, of building a supply route that could pass 10 to 20,000 soldiers per month. At this time,
847-789: A mid-1950s combination of anti-communist Western states and such states in Southeast Asia. The United Kingdom, France and the United States, the latter of which joined after the U.S. Senate ratified the treaty by an 82–1 vote, represented the strongest Western powers. Canada also considered joining, but decided against it in order to concentrate on its NATO responsibilities with its limited defense capabilities. Average of contributions to civil and military budgets between 1958 and 1973: Secretaries-General of SEATO: After its creation, SEATO quickly became insignificant militarily, as most of its member nations contributed very little to

#1732786822964924-406: A not too long a period of time...There is no contradiction in the concept of a protracted war and the concept of taking opportunities to gain victories in a short time." Protracted war theory, however, does not urge rapid conclusion. Palmer suggests that there might be at least two reasons beyond a simple speedup: They may also have believed the long-trumpeted U.S. maxim of never getting involved in
1001-483: A policy commitment to safeguard the South Vietnamese regime directly. The American military forces and other anti-communist SEATO countries increased their support, sending large scale combat forces into South Vietnam; at its height in 1969, slightly more than 400,000 American troops were deployed. The People's Army of Vietnam and the allied Viet Cong fought back, keeping to countryside strongholds while
1078-573: A political dau tranh argument: the U.S. was faced with two unacceptable alternatives: invading the North or continue a stalemate. Invasion of "a member country of the Socialist camp" would enlarge the war, which Giap said would cause the "U. S. imperialists...incalculable serious consequences." As for reinforcements, "Even if they increase their troops by another 50,000, 100,000 or more, they cannot extricate themselves from their comprehensive stalemate in
1155-605: A report on 2 January 1964, for the first operational phase to begin on 1 February. INR determined that the North Vietnamese had, in December, adopted a more aggressive stance toward the South, which was in keeping with Chinese policy. This tended to be confirmed with more military action and less desire to negotiate in February and March 1964 Duiker saw the political dynamics putting Lê Duẩn in charge and Ho becoming
1232-516: Is a coastal estuary island, 25 miles (40 km) long and a maximum of 3 miles (4.8 km) wide, located 15 miles (24 km) east of Huế. During the Battle of Huế in February 1968, South Vietnamese Regional Forces and Popular Forces responsible for the security of the island had been removed to support the battle, allowing the Viet Cong (VC) to establish control of the area. On 9 July 1968
1309-539: Is considered to be the primary force behind the creation of SEATO, which expanded the concept of anti-communist collective defense to Southeast Asia. Then-Vice President Richard Nixon advocated an Asian equivalent of the North Atlantic Treaty Organization ( NATO ) upon returning from his Asia trip of late 1953, and NATO was the model for the new organization, with the military forces of each member intended to be coordinated to provide for
1386-504: The 2nd Battalion, 7th Marines began a one-week sweep of the island but were unable to locate the VC. On 4 September three Regional Force Companies conducting a sweep operation were engaged by the VC and were only able to break contact with helicopter gunship support. It was estimated that at least two VC Companies and possibly a Battalion were located on the island. On 9 September one of the Regional Force companies withdrew from
1463-715: The British Parliament , at one point interrupting a parliamentary debate between Foreign Secretary Anthony Eden and Leader of the Opposition Clement Attlee to excoriate them both for considering the idea. Prince Norodom Sihanouk of Cambodia reported that Foster Dulles went to great efforts to convince him to join SEATO; however, he refused because "I considered SEATO an aggressive military alliance directed against neighbors whose ideology I did not share but with whom Cambodia had no quarrel". In
1540-557: The NATO alliance, SEATO had no joint commands with standing forces. In addition, SEATO's response protocol in the event of communism presenting a "common danger" to the member states was vague and ineffective, though membership in the SEATO alliance did provide a rationale for a large-scale U.S. military intervention in the region during the Vietnam War (1955–1975). Despite its name, SEATO mostly included countries located outside of
1617-818: The Royal Australian Air Force deployed CAC Sabres of its No. 79 Squadron to Ubon Royal Thai Air Force Base , Thailand. The Sabres began to play a role in the Vietnam War in 1965, when their air defence responsibilities expanded to include protection of USAF aircraft using Ubon as a base for strikes against North Vietnam. In addition to joint military training, SEATO member states worked on improving mutual social and economic issues. Such activities were overseen by SEATO's Committee of Information, Culture, Education, and Labor Activities, and proved to be some of SEATO's greatest successes. In 1959, SEATO's first Secretary General, Pote Sarasin, created

#17327868229641694-1006: The SEATO Graduate School of Engineering (currently the Asian Institute of Technology ) in Thailand to train engineers. SEATO also sponsored the creation of the Teacher Development Center in Bangkok, as well as the Thai Military Technical Training School, which offered technical programs for supervisors and workmen. SEATO's Skilled Labor Project (SLP) created artisan training facilities, especially in Thailand, where ninety-one training workshops were established. SEATO also provided research funding and grants in agriculture and medical fields. In 1959, SEATO set up
1771-583: The Tet Mau Than or Tong Kong Kich/Tong Kong Ngia (TCK/TCN, General Offensive-General Uprising ) One of the great remaining questions is if this was a larger plan into which the Battle of Khe Sanh and Tet Offensive were to fit. If there was a larger plan, to what extent were North Vietnamese actions in the period of this article a part of it? Douglas Pike believed the TCK/TCN was to have three main parts: Pike used Dien Bien Phu as an analogy for
1848-1189: The United States . The Philippines and Thailand were the only Southeast Asian countries that actually participated in the organization. They shared close ties with the United States, particularly the Philippines , and they faced incipient communist insurgencies against their own governments. Thailand became a member upon the discovery of the newly founded "Thai Autonomous Region" in Yunnan (the Xishuangbanna Dai Autonomous Prefecture in South West China ) – apparently feeling threatened by potential Maoist subversion on its land. Other regional countries like Burma and Indonesia were far more mindful of domestic internal stability rather than any communist threat, and thus rejected joining it. Malaya (independence in 1957; including Singapore between 1963 and 1965) also chose not to participate formally, though it

Joint warfare in South Vietnam, 1963%E2%80%931969 Anti-Communist forces: Communist forces: United States : 409,111 (1969) During the Cold War in the 1960s, the United States and South Vietnam began a period of gradual escalation and direct intervention referred to as the " Americanization " of joint warfare in South Vietnam during
2002-482: The Vietnam War . At the start of the decade, United States aid to South Vietnam consisted largely of supplies with approximately 900 military observers and trainers. After the assassination of both Ngo Dinh Diem and John F. Kennedy close to the end of 1963 and Gulf of Tonkin incident in 1964 and amid continuing political instability in the South, the Lyndon Johnson Administration made
2079-533: The armed struggle ( dau trinh ) theory espoused by Võ Nguyên Giáp but opposed by the politically oriented Trường Chinh . Pike said he could almost hear Trường Chinh saying, "You see, it's what I mean. You're not going to win militarily on the ground in the South. You've just proven what we've said; the way to win is in Washington." Alternatively, Giáp, in September 1967, had written what might well have been
2156-521: The center of gravity of the opposition. Lyndon Johnson and Robert McNamara , in selecting a strategy in 1965, had assumed the enemy forces were assumed that much as the defeat of the Axis military had won the Second World War, the Communist military was the center of gravity of the opposition, rather than the political opposition or the security of the populace. In contrast, the North Vietnamese took
2233-400: The 1st Cav, so BG Man revised a plan to bring to try to fight the helicopter-mobile forces on terms favorable to the North Vietnamese. They fully expected to incur heavy casualties, but it would be worth it if they could learn to counter the new U.S. techniques, inflict significant casualties on the U.S. Army, and, if very lucky, still cut II CTZ in half. That planned movement was very similar to
2310-790: The Cholera Research Laboratory in Bangkok, later establishing a second Cholera Research Laboratory in Dacca , East Pakistan . The Dacca (now Dhaka) laboratory soon became the world's leading cholera research facility and was later renamed the International Centre for Diarrhoeal Disease Research, Bangladesh . SEATO was also interested in literature, and a SEATO Literature Award was created and given to writers from member states. Though Secretary of State John Foster Dulles considered SEATO an essential element in U.S. foreign policy in Asia, historians have considered
2387-456: The December decision, there was more emphasis on military action and less attention to negotiation. As opposed to many analysts who believed the North was simply unaware of McNamara's "signaling"; INR thought that the North was concerned of undefined U.S. action on the North and sought Chinese support. If INR's analysis is correct, the very signals mentioned in the March 1965 McNaughton memo, which

2464-596: The Manila Pact a failure, and the pact is rarely mentioned in history books. In The Geneva Conference of 1954 on Indochina , Sir James Cable , a British diplomat and naval strategist, cabled the Foreign Office and described SEATO as "a fig leaf for the nakedness of American policy", citing the Manila Pact as a "zoo of paper tigers ". As early as the 1950s Aneurin Bevan unsuccessfully tried to block SEATO in
2541-518: The Maoist doctrine of Protracted War, which itself assumed it would attrit the counterinsurgents . An alternative view, considering overall security as the center of gravity, was shared by the Marine leadership and some other U.S. government centers of opinion, including Central Intelligence Agency , Agency for International Development , and United States Army Special Forces . Roughly until mid-1965,
2618-559: The PAVN created its first division headquarters, under then-brigadier general Chu Huy Man . This goal at first seemed straightforward, but was reevaluated when major U.S. ground units entered the area, first the United States Marine Corps at Da Nang , and then the 1st Cavalry Division (Airmobile) , the "First Cav". In particular, the PAVN were not sure of the best tactics to use against the air assault capability of
2695-571: The PAVN to retreat onto very reasonable paths to break away from the Americans – but different Americans had silently set ambushes, earlier, across those escape routes. By late 1966, however, North Vietnam began a buildup in the northwest area of the theater, in Laos, the southernmost part of the DRV, the DMZ, and in the northern part of the RVN. It is known that the North Vietnamese planned something called
2772-558: The Republic of [South] Vietnam by destroying the VC—his forces, organization, terrorists, agents, and propagandists—while at the same time reestablishing the government apparatus, strengthening GVN military forces, rebuilding the administrative machinery, and re-instituting the services of the Government. During this process security must be provided to all of the people on a progressive basis. Westmoreland complained that, "we are not engaging
2849-457: The SVN-US strategy still focused around pacification in South Vietnam , but it was increasingly irrelevant in the face of larger and larger VC conventional attacks. Military Assistance Command, Vietnam began to refer to the "two wars", one against conventional forces, and the other of pacification . The former was the priority for U.S. forces, as of 1965, assuming the South Vietnamese had to take
2926-463: The South. The U.S. would avoid further Geneva talks until it was established that they would not improve the Communist position. It was estimated that while there would be a strong diplomatic and propaganda response, the DRV and its allies would "refrain from dramatic new attacks, and refrain from raising the level of insurrection for the moment." The U.S/RVN and North Vietnam had strategic goals, with very different, and often inaccurate, definitions of
3003-483: The U.S. and South Vietnam with a protracted warfare model , in their concept of dau tranh , or "struggle", where the goal coupling military and political initiatives alongside each-other; there are both military and organisational measures that support the political goal. Following the Tet Offensive and with US Withdrawal, once the United States was no longer likely to intervene, the North Vietnamese changed to
3080-479: The U.S. had little intelligence collection capability to detect the start of this project. Specifically, MACV-SOG , under Russell, was prohibited from any operations in Laos, although SOG was eventually authorized to make cross-border operations. Before the operations scheduled by the Krulak committee could be attempted, there had to be an organization to carry them out. An obscure group called MACV-SOG appeared on
3157-617: The VC having reached a level of offensive capability rather than capitalizing on the overthrow of Diem. During this period, INR observed, in a 23 December paper, the U.S. needed to reexamine its strategy focused on the Strategic Hamlet Program, since it was getting much more accurate – if pessimistic – from the new government than it had from Diem. Secretary McNamara, however, testified to the House Armed Service Committee, on 27 December, that only

3234-470: The VC with sufficient frequency or effectiveness to win the war in Vietnam." He said that American troops had shown themselves to be superb soldiers, adept at carrying out attacks against base areas and mounting sustained operations in populated areas. Yet, the operational initiative— decisions to engage and disengage—continued to be with the enemy. In December 1963, the Politburo apparently decided that it
3311-465: The alliance. While SEATO military forces held joint military training, they were never deployed because of internal disagreements. SEATO was unable to intervene in conflicts in Laos because France and the United Kingdom rejected the use of military action. As a result, the U.S. provided unilateral support for Laos after 1962. Though sought by the U.S., involvement of SEATO in the Vietnam War
3388-399: The anti-communist allied forces tended to control the cities. The most notable conflict of this era was the 1968 Tet Offensive , a widespread campaign by the communist forces to attack across all of South Vietnam; while the offensive was largely repelled, it was a strategic success in seeding doubt as to the long-term viability of the South Vietnamese state. This phase of the war lasted until
3465-580: The collective defense of the member states. The organization, headquartered in Bangkok , was created in 1955 at the first meeting of the Council of Ministers set up by the treaty. This was contrary to Dulles's preference to call the organization "ManPac" (Manila Pact) to avoid public identification of the pact with NATO. Organizationally, SEATO was headed by the Secretary General, whose office
3542-488: The department of defence breaks down the types of engagements from a periodic study here. William Westmoreland , and to a lesser extent Maxwell Taylor , rejected, if they seriously considered, the protracted war doctrine stated by Mao and restated by the DRV leadership, mirror-imaging that they would be reasonable by American standards, and see that they could not prevail against steady escalation. They proposed to defeat an enemy, through attrition of his forces, who guided by
3619-403: The early 1970s, the question of dissolving the organization arose. Pakistan withdrew in 1973, after East Pakistan seceded and became Bangladesh on 16 December 1971. South Vietnam was defeated in war and annexed by North Vietnam and France withdrew financial support in 1975, and the SEATO council agreed to the phasing-out of the organization. After a final exercise on 20 February 1976,
3696-432: The election of Richard Nixon and the change of U.S. policy to Vietnamization , or ending the direct involvement and phased withdrawal of U.S. combat troops and giving the main combat role back to the South Vietnamese military. One of the main problems that the joint forces faced was continuing weakness in the South Vietnamese government, along with a perceived lack of stature among the generals who rose up to lead it after
3773-688: The incident, and at least some North Vietnamese naval patrols were deployed against these. Possible consequences of such actions, although not explicitly addressing the OPPLAN34A operations, were assessed by the United States Intelligence Community in late May, on the assumption The actions to be taken, primarily air and naval, with the GVN (US-assisted) operations against the DRV and Communist-held Laos, and might subsequently include overt US military actions. They would be on

Everyone encountered in the operation was interrogated by Republic of Vietnam National Police , VC suspects were removed to intelligence centers, while those cleared were escorted to safe areas. Operation Vinh Loc officially concluded on 20 September, VC losses were 154 killed, 370 captured and 56 Chieu Hoi . Allied losses were two killed.

On 10 September Company D, 1st Battalion, 501st Infantry Regiment moved to the northern end of the island, the 2nd and 3rd Battalions of the ARVN 54th Regiment moved to the east of Phu Thu District opposite the island and the 3rd Troop, 7th ARVN Cavalry moved its M113 APCs to Tân Mỹ Base .

Arguably, however, there were three wars: There were, however, changes in the overall situation from early 1964 to the winter of 1965–1966, from 1966 to late 1967, and from late 1968 until the U.S. policy changes with the Nixon Administration. Nixon's papers show that in 1968, as a presidential candidate, he ordered Anna Chennault, his liaison to the South Vietnam government, to persuade them to refuse
4081-540: The lingering threat coming from communist North Vietnam and the possibility of the domino theory with Indochina turning into a communist frontier, SEATO got these countries under its protection – an act that would be considered to be one of the main justifications for the U.S. involvement in the Vietnam War . Cambodia, however rejected the protection in 1956. The majority of SEATO members were not located in Southeast Asia . To Australia and New Zealand, SEATO
4158-650: The next two days, the ARVN would succeed with Operation Thang Lang-Hai Yen 79 on the Dinh Tuong–Kien Phuong Sector border, killing 99 VC, followed the next day by an attack on a training camp in Quảng Ngãi, killing 50. These successes, however, must be balanced by the Buddhist crisis and the increased instability of Diem. After Diem's fall in November 1963 , INR saw the priority during this period as more

In reality, it was the Special Operations Group, with CIA agent programs for the North gradually moving under MACV control – although SOG almost always had a CIA officer in its third-ranking position, the second-in-command being an Air Force officer. The U.S. had a shortage of covert operators with Asian experience in general. Ironically, Assistant Secretary of State Roger Hilsman , who had been
4312-438: The original government of Diem was deposed. Coups in 1963 , January 1964 , September 1964 , December 1964 , and 1965 all shook faith in the government and reduced the trust of civilians. According to General Trần Văn Trà , the [North Vietnamese] Party concluded, the "United States was forced to introduce its own troops because it was losing the war. It had lost the political game in Vietnam." Robert McNamara suggests that
4389-483: The overthrow of Dương Văn Minh by Nguyễn Khánh , in January 1964, reflected differing U.S. and Vietnamese priorities. And since we still did not recognize the North Vietnamese and Vietcong and North Vietnamese as nationalist in nature, we never realized that encouraging public identification between Khanh and the U.S. may have only reinforced in the minds of many Vietnamese that his government drew its support not from
4466-520: The people, but from the United States. The situation in South Vietnam continued to deteriorate with corruption rife throughout the Diem government and the ARVN unable to effectively combat the Viet Cong. In 1961, the newly elected Kennedy Administration promised more aid and additional money, weapons, and supplies were sent with little effect. Some policy-makers in Washington began to believe that Diem

Trà's analysis (see above) was that while the concept of the General Offensive-General Uprising was drawn up by the Politburo in 1965, the orders to implement it did not reach the operational headquarters until late October 1967. Pike described it as consistent with

SEATO The Southeast Asia Treaty Organization ( SEATO ) was an international organization for collective defense in Southeast Asia created by the Southeast Asia Collective Defense Treaty signed in September 1954 in Manila , Philippines.

#17327868229644774-422: The special operations community have risen to four-star rank, including Chairman of the Joint Chiefs of Staff , but special operators were regarded as outcasts, unlikely to rise high in rank, during the Vietnam War. To understand factors that contributed to the heightened readiness in the Gulf, it must be understood that MACV-SOG OPPLAN 34A naval operations had been striking the coast in the days immediately before

The resulting campaign is called the Battle of Ia Drang , with a followup at the Battle of Bong Son , but Ia Drang actually had three major phases: In the larger Battle of Bong Son approximately a month later, which extended into 1966, 1st Cav drew their own lessons from what they believed the PAVN developed as countertactics to air assault , and used obvious helicopters to cause

Losing elite troops during the Tet Offensive never let them develop the "second wave" or "third phase" "We don't ever know what the second wave was; we have never been able to find out because probably only a couple of dozen people knew it." The description of the three fighting methods is consistent with the work of Nguyễn Chí Thanh , who commanded forces in

Further assumptions is that the U.S. would inform the DRV, China, and the Soviet Union that these attacks were of limited purpose, but show serious intent by additional measures including sending a new 5,000 troops and air elements to Thailand; deploying strong air, naval, and ground strike forces to the Western Pacific and South China Sea; and providing substantial reinforcement to

For example, on 23 March 1964, ARVN forces in Operation Phuong Hoang 13-14/10, Dien Phong Sector, raids a VC battalion in a fortified village, killing 126. On 13 April, however, the VC overran Kien Long (near U Minh Forest ), killing 300 ARVN and 200 civilians. On 25 April, GEN Westmoreland was named to replace GEN Harkins; an ARVN ambush near Plei Ta Nag killed 84 VC. Ambassador Lodge resigned on 23 June, with General Taylor named to replace him. In
5159-517: Was also in Bangkok. A total of eight members joined the organization in its lifetime. Primarily created to block further communist gains in Southeast Asia, SEATO is generally considered a failure, as internal conflict and dispute hindered general use of the SEATO military; however, SEATO-funded cultural and educational programs left longstanding effects in Southeast Asia. SEATO was dissolved on 30 June 1977, after many of its members lost interest and withdrew. The Southeast Asia Collective Defense Treaty
5236-447: Was created in 1957 at a meeting in Canberra , with a council of representatives from member states and an international staff. Also present were committees for economics, security, and information. SEATO's first Secretary General was Pote Sarasin , a Thai diplomat and politician who had served as Thailand's ambassador to the U.S. between 1952 and 1957, and as Prime Minister of Thailand from September 1957 to 1 January 1958. Unlike
5313-427: Was denied because of lack of British and French cooperation. Both the United States and Australia cited the alliance as justification for involvement in Vietnam. U.S. membership in SEATO provided the United States with a rationale for a large-scale U.S. military intervention in Southeast Asia. Other countries, such as the UK and key states in Asia, accepted the rationale. In 1962, as part of its commitment to SEATO,

There were five broad categories, to be planned in three periods of 4 months each, over a year: Lyndon Johnson agreed with the idea, but was cautious. He created an interdepartmental review committee, under Major General Victor Krulak , on 21 December, to select the least risky operations on 21 December, which delivered
5467-442: Was incapable of defeating the communists, and some even feared that he might make a deal with Ho Chi Minh. Discussions then began in Washington regarding the need to force a regime change in Saigon . This was accomplished on 2 November 1963, when the CIA allegedly aided a group of ARVN officers to overthrow Diem. To help deal with the post-coup chaos, Kennedy increased the number of US advisors in South Vietnam to 16,000. OPPLAN 34A
5544-545: Was kept updated with key developments due to its close relationship with the United Kingdom. The states newly formed from French Indochina ( North Vietnam , South Vietnam , Cambodia and Laos ) were prevented from taking part in any international military alliance as a result of the Geneva Agreements signed 20 July of the same year concluding the end of the First Indochina War . However, with
