CIA activities in Vietnam were operations conducted by the Central Intelligence Agency in Vietnam from the 1950s to the late 1960s, before and during the Vietnam War. After the 1954 Geneva Conference, North Vietnam was controlled by communist forces under Ho Chi Minh's leadership. South Vietnam, with the assistance of the U.S., was anti-communist under Ngo Dinh Diem's leadership. The economic and military aid supplied by the U.S. to South Vietnam continued until the 1974. The CIA participated in both the political and military aspect of the wars in Indochina.[1] The CIA provided suggestions for political platforms, supported candidates, used agency resources to refute electoral fraud charges, manipulated the certification of election results by the South Vietnamese National Assembly, and instituted the Phoenix Program. It worked particularly closely with the ethnic minority Montagnards, Hmong, and Khmer.[2] There are 174 National Intelligence Estimates dealing with Vietnam, issued by the CIA after coordination with the U.S. intelligence community.[3]
Through 1954, Vietnam was part of French Indochina, along with Laos and Cambodia. During the war, the Imperial Japanese Army occupied Vietnam and remained there until 1945, when the Axis powers were defeated. The Japanese were removed from Vietnam with the help of revolutionary leader Ho Chi Minh and his Viet Minh forces.[4] Following the war, France began to reoccupy the Indochina region and reassert its former dominance. Much of this can be traced back to a desire to restore French glory and national pride after the humiliation the nation suffered during the course of World War II. The French also wished to reclaim the Indochina region to regain control over the vast rubber plantations across the country.
The people of Vietnam were completely against the return of the French. The Vietnamese experienced a lot of abuses by the French during their colonization in the mid 19th century. The people of North Vietnam rallied around their recently returned revolutionary leader Ho Chi Minh and looked to him to gain at long last, their independence.[5]
The French spent nine years (1946–54) attempting to regain control of Vietnam. France did not realize that the current Vietnamese were much stronger than those that they were familiar with. They greatly underestimated the strength and capability of the Communist Vietnamese force. The Viet Minh, or Viet Cong as they came to be called, were not going to let the French take control of their region without a fight. The men of the Viet Cong were communists and did not want to surrender their beliefs to the French. Together with the North Vietnamese army, they would defend their land. The Viet Minh used military and political tactics to expel the French from their lands. North Vietnamese troops were prepared to fight the French to the bitter end in order to ensure victory and their freedom. The loss of thousands of French men made it easy for North Vietnam and the Viet Cong to win the war. France lost a lot of their supporters of the war after many of their men were killed. It was also beneficial to the North Vietnamese efforts when they began to receive outside assistance. The Soviet Union sent military hardware that they used in combat against the French. After suffering a major defeat at Dien Bien Phu on May 7, 1954, France lost control of Viet Nam above latitude 17 degrees north; this came to be the Democratic Republic of Viet Nam. Soviet- and Chinese-made weapons and captured American ones given to the North Vietnamese army by China played a key role in the defeat of France.
The CIA held classified documents which detail the threat of the Viet Cong or the Vietnamese Communists against the French. The CIA feared the loss of control of Vietnam. They wished for the French to remain in power. The six-page document from 1950, explains the position of the Central Intelligence Agency on Indochina. While the Viet Cong was trying to expel France from power in Vietnam, there was also a fear that there would be an intervention from the Chinese Communists. Regardless of this, the CIA knew that losing Vietnam to Communism would place the rest of Southeast Asia at risk.[6]
Even before the CIA was formed, teams from the OSS, including one under Major Archimedes Patti, was in French Indochina, assessing the situation, and discussing alternatives with parties on all sides, including Ho Chi Minh.
CIA officers moved to French Indochina in 1950 as a part of the legation of the United States in the city of Saigon. After their arrival, CIA involvement expanded to a new large base in Hanoi. The CIA's activities in Vietnam did not grow any further due to the French discouraging CIA activity (the French were still clinging to the idea that they could one day still dominate Vietnam and the U.S. was against this course of action).[7]
CIA involvement in Vietnam was discouraged by the French because it was found that the CIA would often bypass them to open channels to Vietnamese nationalists. CIA activity expanded when the Indochina region became three separate states and grew exponentially during the French War in 1953 to 1954 when France was essentially forced to accept American assistance with unconventional warfare activities.
Despite this resilience by the French, CIA intelligence perceived a deteriorating situation in Vietnam. A 1950 CIA intelligence report noted that the threat of Communism in Indochina was rising as rebel attacks on French outposts continued and highlighted the weaknesses of the French. An intelligence report on Indochinese military developments revealed how vulnerable the French military was, due to the fall of the French border holding at Dong Khe, as well as some attacks they had suffered in Tonkin. The report doubted France's ability to hold Indochina much longer if the Viet Minh continued to attack.[8] The authors of the report feared that, "if these attacks [were to] develop into a coordinated, a large-scale Viet Minh offensive, an action which [might] soon be within Viet Minh capabilities, French maintenance of control over Indochina – by means of their own forces alone – [would] be seriously threatened." This document also noted French hesitancy to bolster the Viet Minh, "apparently fearing that such a step would weaken their ability to contain Vietnamese nationalism."[8]
U.S. intelligence community notes how cautious the French were in arming a Vietnamese army. The report further claimed that "French reluctance to expand or strengthen the Vietnamese National Army is indicated by insistence on allocation and distribution of US military aid under French control, failure to make plans for necessary financing, inability of French officials to agree on a course of action or policy, and refusal to expand the local militia." Additionally, the French officially refused to accept help from the U.S. in the form of training Vietnamese troops by US military instructors. There is a suggestion at the end of the report that the French would need to accept American aid to train the Vietnamese army and to supply them, if they wanted to change their policy of arming the Vietnamese.[8]
During 1953–1954, the involvement of the CIA increased when the French finally accepted U.S. assistance with the unconventional (guerrilla) warfare tactics they faced, as the French were facing large and costly losses at the hands of what would become the Viet Cong and the North Vietnamese forces.[9] The primary aid initially offered by the U.S. was military aid in supplying military hardware and training of the Vietnamese army; the scope of U.S. aid to the French was greatly expanded during and after the Eisenhower administration. Without aid from the United States, there would be little practical effect from this ostensible change in French policy.[10]
There was a reestablishment of a covert action section in Saigon Station. There was also unilateral covert action which was suspended in 1953 under State Department pressure. This was due to the French exposing paramilitary operations against the Vietminh in Ha Noi that the agency did not previously clear with them.[11]
The CIA's mission in Saigon was to directly assess the nationalist politicians.[12] The primary cause and motivation behind the intervention of the U.S. and CIA through 1954 was to gather intelligence and provide interpretations of the events that occurred in Indochina through an American perspective. Outside of North Vietnam, the agency's broad span of activities reached into almost every aspect of the Indochina war. The agency conducted several paramilitary programs and conducted a full-scale war in Laos and South Vietnam.
Following the French defeat at Dien Bien Phu in May 1954, the United States anticipated the expansion of Communism in Vietnam and Southeast Asia as a whole, if they should sit aloof and keep to the French resilience of not needing their support.[13] The CIA became convinced that without any action the southern part of Vietnam would fall to the communist control just as the North had been captured by the communist forces. The CIA without the approval of the State, supported Diem to step up a strong foothold in the Vietnamese region in the same year. The CIA's support for Diem could be traced to 1952, through an established relationship with his brother, Ngo Dinh Nhu.[14] The move by the CIA was purposely aimed to wean the southern part from the Communist-controlled north through the 17th parallel. In order to prevent the North Communist military from gaining control over the entire Vietnamese region, the CIA and Diem's Special Forces established the rural self-defense units to mark the beginning of American counterinsurgency efforts in Vietnam. For the immediate nine years, the CIA will continue to work closely with Ngo Dinh Nhu to aid Diem in establishing national political institutions in South Vietnam.[15]
In 1954, the CIA would remain consistent in its activities in Vietnam. The CIA's expansion included various stations throughout Vietnam and Laos. A station was also located in Cambodia, but relations with that country were broken off in 1963 and reinstated only during the 1970s. The CIA stations, though initially used solely for gathering intelligence and providing interpretations of events in Indochina, came to gain as much importance as the U.S. embassy in its scale of political relations with the South Vietnamese government due to its broad range of activities. The CIA stations in Vietnam were also responsible for conducting a full-scale war in Laos at that time in addition to South Vietnam paramilitary operations.
In 1961, the U.S. government entrusted the CIA with irregular operations in Laos with the intent of negotiated settlement. In Vietnam, U.S. Army Special Forces teams were engaged in tribal programs similar to the one with Vang Pao. However, the CIA was in operation control because any deployment of Vietnam-based units to or across the Laotian border would be clandestine. The CIA was instructed by Washington to make decisions and which indigenous elements would participate.[16]
Another key event that occurred in 1954 was the creation of the Geneva Accords. Signed by France, Great Britain, the Soviet Union, China, and three Associated States of Indochina including Ho Chi Minh's Democratic Republic of Vietnam, the Accords addressed the issue of what to do with Vietnam since the Viet Minh had ended colonial rule in the north. Although the United States had agreed to respect the Accords, it would not sign them because the U.S. government disagreed with the provision that split Vietnam at the 17th parallel.[17] These Accords would come to play a major role in the United States' decision to interfere with the situation in Vietnam. The U.S. government had provided the French with logistical support in their mission to defeat the Viet Minh. It was only a matter of time, however, before the French needed military support as well. Essentially, the Geneva Accords forced the United States to decide if it was willing to provide such assistance. As historian Thomas L. Ahern Jr stated, "In the end, the importance of halting Communism overshadowed the risks, and the United States embarked on its 21-year effort to create in South Vietnam a permanent barrier to Communist expansion in Southeast Asia."
The new CIA team in Saigon was the Saigon Military Mission, headed by United States Air Force Colonel Edward Lansdale, who arrived on June 1, 1954. His diplomatic cover title was Assistant Air Attaché. The broad mission for the team was to undertake paramilitary operations against the enemy and to train the ARVN in the arts of psychological warfare, just like Lansdale had done in an earlier conflict in the Philippines. Although Lansdale worked for the OSS briefly in World War II, he was never a CIA employee.[11]
Working in close cooperation with the U.S. Information Agency, a new psychological warfare campaign was devised for the Vietnamese Army and for the government in Hanoi. Shortly after, a refresher course in combat psy-war was constructed.
One example of psychological warfare dealt directly with misinformation. Lansdale would later recall the event in his memoirs: "The first idea was used just before the French quit the city of Hanoi and turned over control to the Viet Minh. At the time, the Communist apparatus inside the city was busy with secret plans to ready the population to welcome the entry of Viet Minh troops. I suggested that my nationalist friends issue a fake Community manifesto, ordering everyone in the city except essential hospital employees to be out on the streets not just for a few hours of welcome but for a week-long celebration. In actuality this would mean a seven-day work stoppage. Transportation, electric power, and communication services would be suspended. The simple enlargement of plans already afoot should give the communists an unexpectedly vexing problem as they started their rule."[18] The celebration did not last a week. The Communists thought that this manifesto was French counterpropaganda and attempted to order everyone back to work, which took three days.[18]
The second SMM member, Major Lucien Conein, arrived on July 1. A paramilitary specialist, well known to the French for his help with French-operated maquis in Tonkin against the Japanese in 1945, he was the one American guerrilla fighter who had not been a member of the Patti Mission. In August, he went to Hanoi with the assignment of developing a paramilitary organization in the north.... A second paramilitary team for the south was formed, with Army Lieutenant Edward Williams doing double duty as the only experienced counter-espionage officer, working with revolutionary political groups.[17]
Working with available data, the CIA produced a National Intelligence Estimate in August 1954. It began by stating that the Communist signing of the Geneva agreements had legitimized them, and they would need to immediately move to control the North while planning for long-term control of the country. It went on to say that the Viet Minh "will probably emphasize social and economic reforms and the participation of all political, economic, and religious groups in state activity."
This National Intelligence Estimate went on to suggest that while the Diem government was in official control of the South, it remained unpopular because of a disconnect of the government from the people. Certain pro-French elements may have been planning to overthrow it. CIA experts also noted that Diem would have political issues on top of already sinking popularity. Viet Minh elements would remain in the South and create an underground resistance force, discredit the government, and undermine French-Vietnamese relations.[19]
On October 26, 1954, Lansdale lured two key personnel in a planned coup against South Vietnamese President Ngo Dinh Diem out of the country. Lansdale invited Hinh and staff to visit the Philippines.
U.S. personnel dealing with the Government of Vietnam had difficulties understanding Vietnamese politics. This can be attributed to the fact that the CIA did not make a concerted effort to gain a better understanding of the history and culture of Vietnam. The CIA instead focused on the military forces occupying the territory instead of the political and economic forces that motivated them.[20] The diplomats were not getting clear information in 1954 and early 1955, but the CIA station "had ... no mandate or mission to perform systematic intelligence and espionage in friendly countries, and so lacks the resources to gather and evaluate the large amounts of information required on political forces, corruption, connections, and so on."
In Thomas Ahern's monograph, he stops short of saying that the agency was an actor in the coup that overthrew South Vietnamese leader Ngo Dinh Diem. Within the monograph it is noted that on the morning of the coup the U.S. Military Command in Vietnam (MACV) advised the CIA that Saigon was quiet, and that the CIA should stop reporting a coup was imminent or in progress. The CIA also reportedly recognized that Diem would have political issues as early as August 1954. It is reported that policy surrounding Diem was set with this in mind. Relations with Diem's brother, Ngo Dinh Nhu, began as early as 1952, also signaling that the CIA predicted issues with Diem. Despite having the benefit of expert warnings, it is clear that the CIA acted beyond the scope of its experts.
By 31 January 1955, a paramilitary group had cached its supplies in Haiphong, having had them shipped by Civil Air Transport, a CIA proprietary airline belonging to the Directorate of Support.
Ngo Dinh Diem and Ngo Dinh Nhu had been exploited by the help of CIA advisors to help defeat one of the challenges to the new Prime Minister's authority.
Lansdale and the South Vietnamese leader Ngo Dinh Diem had been working together; however, they did not agree on the government system they wanted in South Vietnam. In August 1955, Lansdale brought Juan Orendain, a Filipino constitutional scholar, to Saigon in order to sway Diem in a direction similar to the American system. Lansdale was hoping he could have the same effect on Diem as he had previously when working with Magsaysay in the Philippines. Part of this meant proposing a legislature and a judicial system to signal that Diem was open to checks and balances and was not trying to be beyond reproach in his position. By April 1956 Diem had considered and rejected the model proposed by Orendain and was more concerned about the broad authority he needed that very moment. All the while Lansdale had little to no real oversight from the rest of the CIA as these actions were taking place. Though he took advantage of this autonomy to improvise, it also meant he had little to no backup to enforce or further persuade Diem into a governmental separation of powers.
During one encounter in early 1955, Diem rejected US ambassadorial representative J. Lawton Collins's nominee for commander of the Army of Republic of Vietnam. Collins wanted competence, whereas Diem preferred someone loyal.
On April 27, 1955, the Battle of Saigon had begun. The private crime syndicate Binh Xuyen and the Vietnamese National Army would wage conflict for around a month in Cholon. The Binh Xuyen had been influential (as a powerful Saigon gang) in post-colonial Vietnam, and had even stolen arms and fought the French, however they were defeated quickly.[21] Diem had issued the Binh Xuyen an ultimatum to come under control or be eliminated. The damage caused by the fighting resulted in around a thousand casualties, and tens of thousands more homeless.
In January 1956 Diem promulgated Ordinance 6, which authorized detention and reeducation for anyone considered a danger to the state. This led to a problem of overcrowding as there were already 20,000 alleged communists that had been placed in detention camps since 1954, according to Diem's Information Ministry.[22] Lansdale claimed that there were 7,000 political detainees in Saigon's Chi Hoa prison alone.
Operation Brotherhood, created by Ramon Magsaysay in the Philippines, had its first medical team beginning in late 1954. By 1955, it had more than 100 doctors and nurses at 10 medical center locations in South Vietnam to treat refugees and to train Vietnamese medical personnel. The second pacification operation was launched late April 1955 in the southern Dinh Dinh and northern Phu Yen portion of Central Vietnam.[11]
North Vietnamese troops needed a way to link themselves with their allies in Southern Vietnam. The Viet Cong and North Vietnamese soldiers were able to supply troops and military operations through secret tunnels and the Ho Chi Minh trail. The Ho Chi Minh trail was an interlocking trail system that was created through the borders of Laos and Cambodia that reach from North Vietnam to South Vietnam. During the construction of this trail, native guides had to be used to guide the North Vietnamese troops through the wild countryside. Campsites that were built along the side of the trail grew into way points for troops to gather and rest. The trail stretched 800 miles and could take up to three months to travel by foot.[23] Laos had been demilitarized during the 1960s. The North Vietnamese however did not respect the Laos treaty with the U.S., Instead, the North Vietnamese disregarded the peace treaty and begun their construction of the trail to aid their southern Vietnamese allies. Pictures revealing the trail's construction were taken by Vietnamese journalists. However, some of the greatest dangers were not the humans following the trail but rather the mother nature one would encounter along the way. Guides were needed for groups to navigate the dangerous trail. Snakes and spiders would flood the clothing of travelers along with dangerous terrain. For these reasons, travelers needed to practice great precaution along the way. The trail quickly became one of the secret forces of the war. Once United States officials gathered intelligence about the trail, they quickly installed motion sensors across the trail to catch insurgents. The complexity of the trail grew further during the 1960s.
Detecting Viet Cong movements on the Ho Chi Minh trail was exceedingly difficult. The trail was a complex collection of interconnecting footpaths. The flexibility afforded by its complexity meant multiple routes could be traversed from north to south. As such, it was easy to shift to a different route if the security of one area was compromised. Furthermore, the length of the trail and the small number of persons using it on any given segment, coupled with its flexible nature made detection all but impossible.[24]
In attempts to combat troop and supply movement along the trail, the CIA and U.S. military set up heat and movement sensors along the trail to track enemy movement. U.S. forces also attempted to use air dropped listening devices to track enemy troops and pinpoint Viet Cong movements.
1959 also saw the arrival of William Colby in the region, and it became increasingly noticeable throughout 1959 that Diem was becoming paranoid regarding security issues and the military. This time saw a constant back and forth between Diem and Nhu over control of the military in the region. The year 1959 saw Diem's authority quickly being lessened, as Tran Quoc Bhu had insisted upon it.
The CIA had very few contacts in the Viet Cong ranks or North Vietnam at the time. Many of the contacts that they had were double agents run by the Viet Cong. Much of the intelligence gathered regarding North Vietnam was unreliable.[25] U.S. and South Vietnamese military personnel believed that the bulk of North Vietnamese supplies were being shipped over the Ho Chi Minh trail, however, more than 80 percent of Northern supplies were sent by sea.
U.S. Special Forces also began to train some Laotian soldiers in unconventional warfare techniques as early as the fall of 1959 under the code name Erawan.[26] This was because after President Kennedy took power who refused to send more American soldiers to battle in Southeast Asia. Instead, he called upon the CIA to use its "tribal forces" in Laos and to "make every possible effort to launch guerrilla operations in North Vietnam with its Asian recruits." Hence, under this code name, General Vang Pao, who served the royal Lao family was recruited. He then recruited and trained his Hmong soldiers to ally with the CIA and fight against the communist North.
In April 1961, Lansdale, who had been designated the Operations Officer for an interagency Task Force in charge of political, military, economic, psychological, and covert character, was to go to Vietnam. Changes of policy in Washington however, transferred these responsibilities to the military and diplomats, and Lansdale was no longer involved with Vietnam.
On May 11, 1961, President Kennedy gave the authorization to begin "a program for covert actions to be carried out by the Central Intelligence Agency which would precede and remain in force after any commitment of U.S. forces to South Vietnam."[22] Kennedy was giving the CIA the job of preparing for the eventual landing of U.S. troops. Later that year, in October 1961 the Director of Central Intelligence Allen Dulles approved a massive counterinsurgency program with the goal of launching a "village defense program in the lightly populated but strategically important Central Highlands."[22] The involvement of the CIA rose substantially when they were given the task of supporting "irregular formations" that did not fall under other agencies' jurisdictions, which include civil wars, guerrilla wars, and rebellions.[22] They were given this job because of an interagency task force recommendation in January 1962. Later that year in May 1962, Defense Secretary McNamara promised the Far East Division chief Desmond FitzGerald "a blank check...in terms of men, money, and material."[22] This illustrates the important mission given to the CIA by the Department of Defense and the White House.
CIA begins to sponsor and train the Civilian Irregular Defense Groups (CIDG) in the South-Central Highlands. These were local defense operations with a mobile support component, "Mike Force", made up primarily of Nung mercenaries. Most CIDG units eventually became Vietnamese Rangers. These forces were intended to help combat the guerrilla tactics of the Vietcong.The CIDG grew out of a Military Operations Section (MOS) program led by Gilbert Layton. Layton's priority was strengthening the intelligence network in the country, specifically in the border regions with Cambodia and Laos.[22] Layton sought to find locals that could gather intelligence on Viet Cong installations in the area.[22] He proposed a program "designed to recruit as many as 1,000 tribesmen to operate in the guerrilla-infested high plateau areas bordering on northern Cambodia and South Laos."[22] His proposal for a crop station and seed distribution was approved but it suffered many delays and problems.[22] CIA Deputy Chief William Colby expanded the intelligence gathering operation into a defense building operation known as the "Montagnard defense program."[22]
In 1961, the CIA also strengthened contact with then-captain in the Royal Laotian Armed Forces, Vang Pao.[27] Pao was a member of the nomadic Hmong tribe, a southeast Asian ethnic minority dwelling primarily in the mountains of Laos, Thailand, and Vietnam, and the CIA quickly realized the potential use of the Hmong as guerrilla fighters against Laotian as well as North Vietnamese communist forces. First donations of food, blankets, and then by January 24, 1961, 300 Hmong received weapons to Vang Pao's troops, the CIA sent men to train Hmong fighters in guerrilla tactics, eventually engaging soon-to-be-General Pao's approximately 10,000 men.[28] These Hmong forces would prove valuable to the CIA's tactics for the remainder of the war, despite insecurities on both sides as to the allegiance of the other. It was during 1961 that Vang Pao expressed concerns as to the dedication of the CIA in aiding and remaining supportive of the Hmong after their use in the Vietnam War.[29]
Laos, in 1961, was more important than even the incoming president knew. Kennedy had organized a meeting with Eisenhower, who was on his way out of the Oval Office, to discuss the strategic importance of Laos. They discussed "keeping the 'cork in the bottle'...to prevent communist dominion over most of the Far East."[30] Eisenhower saw Laos as so important, that he was worried about all of Thailand, Cambodia, and South Vietnam falling to communism if Laos went that way. The president was concerned that the Royal Laotian Army (RLA) was impotent and mutinous and did not want to rely on them. He was so concerned, that in this meeting, he said he would "as a last desperate hope...intervene unilaterally," if it were up to him. The interventions, as mentioned in the paragraph above, ended up being the arming and training of paramilitary forces. While preventing a communist Laos remained the objective of the CIA for the next 14 years, the focus of their paramilitary operations changed over time. Until 1964, the Hmong fighters in Laos focused on trying to fight back North Vietnamese fighters and on preventing further encroachment. They were highly important, because the U.S. hadn't begun putting troops on the ground in any great numbers, yet. After that, in 1965, the report describes the Hmong activities in Laos as "flitt[ing] over mountain trails or mov[ing] by air to occupy key high ground and to harass Hanoi's tanks and artillery," meaning that U.S. troops took on a frontline role and asked the paramilitary forces to operate in more difficult terrain and in less standard ways.
The Buon Enao Project
Buon Enao was a Rhadé village that was the location of a CIA experimental program designed to strengthen defenses against the Viet Cong. The CIA brought several proposals to the village elders, and almost all were met with protest or skepticism. After satisfying all of their concerns, the Americans were able to build a perimeter border fence as well as dispensary. They also armed the villages and trained them how to shoot. They were named the CIDG so that they did not give the appearance of a "covert offensive military unity." Buon Enao was the "first CIDG Area Development Center, which controlled social and economic development services as well as the village defense system in the surrounding area."
Tony Poe was recruited into the CIA after he graduated from San Jose State University and finished his training in 1953. Poe worked with the Hmong starting in March 1961. He was then transferred to Long Tieng. In Long Tieng Poe ran field missions with the Hmong partisans.[31] After he took an enemy round in the stomach in January 1965, and one-too-many confrontations with Vang Pao, Poshepny was transferred up-country, to the land of Yao tribesmen. The tribesmen thought of him as "a drinker and an authoritarian commander and a mercurial leader, who could threaten and bribe to get his way" He died on June 27, 2003.
In February 1962, two disgruntled South Vietnamese air force pilots bombed the presidential palace in hopes of killing Diem and forcing a new leadership, but their plan failed as he was in a different part of the palace when the attack happened. Diem reassigned military officers to improve his security, however, he still did not undertake political reforms.[32] It was also agreed upon in 1962 to grow the Laotian irregulars despite potential diplomatic consequences.[33]
In the Spring of 1962, the CIA became interested hitting at North Vietnam's navy; the agency called it Operation VULCAN. In order to fulfill this operation, the CIA hired "18 South Vietnamese who had been trained in underwater demolition" to target the port of Quảng Khê, which "was home to several of the DRV's Swatow-class gunboats". The CIA was able to get The USS Catfish to do reconnaissance, and intelligence collection. the World War Two era submarine confirmed that the Swatows were indeed at Quang Khe. Aerial Reconnaissance confirmed three Swatows each having "frogmen" attached to their demolition.[34] In June 1962, the demolition crew, called the "frogmen", were carried by the Nautilus III within swimming distance of the North Vietnamese port, at which point the divers swam to the various military ships in the port and attached their bombs. However, "how many of them detonated remained unclear, for one of them went off prematurely, with the swimmer already spotted and trying to escape". One Frogman is believed to have been caught in the explosion of one gunboat and died.[35]
