1965 in the Vietnam War

1 January

The South Vietnamese security forces, including the Army of the Republic of Vietnam (ARVN), Regional and Popular Forces, Montagnard irregulars and National Police totaled 567,246 personnel.[1]^:20 23,310 U.S. military personnel were in South Vietnam.[2]

The number of VC guerrillas and PAVN regulars in South Vietnam was a matter of much debate. One U.S. government estimate was that the VC consisted of 40,000 full-time fighters and 80,000 to 100,000 part-time guerrillas.[1]^:19 The Department of Defense's fact book estimated that the VC numbered less than 200,000 plus 39,175 political cadre.[3]^:34 These numbers presumably included thousands of PAVN soldiers and cadre infiltrated during the previous five years. The first PAVN units dispatched to South Vietnam, consisting of three regiments (about 5,000 men), had arrived in South Vietnam in late 1964.[4]^:200 A junior-level Central Intelligence Agency (CIA) analyst, Samuel A. Adams, had just begun work estimating VC numbers; he would later conclude that MACV underestimated VC strength by about one-half.[1]^:20[3]^:84

Both North Vietnam and the United States would rapidly increase the number of their troops in South Vietnam during 1965.

The Battle of Binh Gia concluded as the PAVN/VC withdrew from the battlefield. In six days of fighting, the VC 9th Division had killed 201 South Vietnamese soldiers from the Airborne Division, Marine Division and Rangers and five American advisers.[5]^:302–3

3 January

Senator Mike Mansfield, considered the U.S. Congress's most knowledgeable person about Vietnam, appeared on television and said that neutralization of South Vietnam through an agreement reached by negotiations between the U.S. and the communist powers might be the best solution to the war. Mansfield was one of several senators who had doubts about the course of U.S. policy in South Vietnam.[5]^:305–6

6 January

The Armed Forces Council made a show of officially renouncing all their power to Prime Minister Tran Van Huong, who was asked to organize elections.[6]^:350 They also agreed to appoint a civilian body and release those arrested in the December coup.[7]^:297

The U.S. Ambassador to South Vietnam General Maxwell Taylor summed up the situation in a telegram to the U.S. government in Washington. "We are faced here with a seriously deteriorating situation characterized by continued political turmoil, irresponsibility and division within the armed forces, lethargy in the pacification program, some anti-US feeling which could grow, signs of mounting terrorism by VC directly at US personnel and deepening discouragement and loss of morale throughout SVN. Unless these conditions are somehow changed and trends reversed, we are likely soon to face a number of unpleasant developments ranging from anti-American demonstrations, further civil disorders, and even political assassinations to the ultimate installation of a hostile govt which will ask us to leave while it seeks accommodation with the National Liberation Front and Hanoi."

Taylor opposed the introduction of U.S. ground units to help fight the VC (as proposed in frustration by President Johnson a few days earlier), endorsing instead a U.S. policy of graduated air attacks against the Ho Chi Minh trail, the supply line for the PAVN/VC itself.[8]

9 January

Huong and the South Vietnamese military again reiterated their commitment to civilian rule through an elected legislature and a new constitution, and that "all genuine patriots" would be "earnestly assembled" to collaborate in making a plan to defeat the communists.[7]^:297 Khánh and Taylor were both signatories to this announcement.[9]^:122

20 January

While Buddhist protests against the government and the United States intensified, including the burning of a United States Information Service library, Ambassador Taylor met with a Buddhist leader. He said the Buddhists wanted peace and told Taylor that the leaders of South Vietnam were only interested in the benefits they could derive personally from American aid and would otherwise capitulate to the VC. The Buddhists had been protesting against the government of South Vietnam for the previous two years.[5]^:212

26 January

In a speech, former Vice President Richard Nixon argued the U.S. military effort should be escalated to destroy communist supply lines and staging areas in Laos and North Vietnam. He said the U.S. must "either get out, surrender on the installment plan through neutralization, or... find a way to win."[10]

27 January

Amidst continuing political chaos in South Vietnam, General Nguyễn Khánh and the Armed Forces Council overthrew the civilian government of Trần Văn Hương in a bloodless coup, replacing Houng with civilian Nguyễn Xuân Oánh. Khánh, who had been Prime Minister during most of 1964, had been hovering in the background for some time, so the coup d'état was not a great surprise. Ambassador Taylor cabled Washington that Khánh had an alliance with the Buddhist Institute headed by Thích Trí Quang. Taylor said, "The most sinister aspect of this affair is the obvious danger that the Buddhist victory may be an important step toward the formation of a government which will eventually lead the country into negotiations with Hanoi and the National Liberation Front [VC]."[5]^:316

In response to the coup, National Security Council director McGeorge Bundy and Secretary of Defense Robert McNamara wrote a memo to President Johnson. They gave the President two options: use American military power to defeat the insurgency, or negotiate thus attempting to "salvage what little can be preserved." McBundy and McNamara favored the first option; Secretary of State Dean Rusk disagreed. Johnson accepted the military option and sent a telegram to Ambassador Taylor in Saigon saying "the U.S. will spare no effort and no sacrifice in doing its full part to turn back the Communists in Vietnam." President Johnson had crossed the Rubicon.[5]^:317–9

27 January - 4 February

In Laos two coups took place. On 27 January General Phoumi Nosavan once again attempted to seize control of the government but was opposed by forces loyal to General Kouprasith Abhay. On 29 January Colonel Bounleut Saycocie independently mounted his own coup, but after a short term takeover of Vientiane's radio station and infrastructure his forces returned to Government control and were then used by Kouprasith to suppress Phoumi's coup.[11]^:123–5

7 February

A destroyed helicopter at Camp Holloway

The VC attacked Camp Holloway near Pleiku killing eight Americans, wounding 128, destroying 10 U.S. aircraft and damaging a further 15. McGeorge Bundy (visiting South Vietnam) and General Westmoreland visited Pleiku that day. Bundy strongly recommended a reprisal attack against North Vietnam.[12]^:215 Bundy reported to Johnson "The situation in Vietnam is deteriorating and without new U.S. action defeat appears inevitable--probably not in a matter of weeks or perhaps even months, but within the next year or so.... There is still time to turn it around, but not much."[13]^:14

In retaliation, President Johnson ordered Operation Flaming Dart: 49 retaliatory sorties by American and Republic of Vietnam Air Force (RVNAF) planes targeted PAVN bases near Đồng Hới; a second wave targeted VC logistics and communications near the Vietnamese Demilitarized Zone (DMZ). Among the pilots was Air Marshal Kỳ. Poor weather limited the damage caused by the strikes. One plane and its pilot were lost.[14]^:58[12]^:218–9

The Premier of the Soviet Union, Alexei Kosygin, was visiting Hanoi during the bombing. The Soviets were furious that an American attack was carried out while Kosygin was present and motivated to provide additional assistance to North Vietnam.[15]

Bundy sent a memorandum to President Johnson advocating "a new US action" without which "defeat seems inevitable." McBundy said that "any negotiated US withdrawal today would mean surrender on the installment plan."[16]

8 February

HAWK missiles overlooking Da Nang Air Base

The USMC 1st LAAM Battalion based on Okinawa arrived at Da Nang Air Base and by 9 April its HAWK SAMs were operational at the base.[17]^:4–5

9 February

As bombing of North Vietnam continued, the People's Republic of China issued a statement that "We warn U.S. imperialism: You are overreaching yourselves in trying to extend the war with your small forces in Indochina, Southeast Asia, and the Far East. To be frank, we are waiting for you in battle array."[18] On the same day, U.S. National Security Adviser McGeorge Bundy told Senator Mike Mansfield that the Johnson administration "was willing to run the risk of a war with China" if an invasion of North Vietnam was deemed necessary.[19]

The U.S. Embassy in Moscow was attacked by a mob of about 3,000 Asian and Russian students who were protesting against the American bombing of North Vietnam. Two reporters, Adam Clymer of the Baltimore Sun and Bernard Ullman of the Agence-France news agency, were injured, and more than 200 windows in the building were shattered before Moscow police intervened.[20]

The first twenty of 1,819 wives and children of South Vietnam-based American civilian and military personnel departed that nation, by order of President Johnson.[21] The rest, including the dependents of Ambassador Taylor and General Westmoreland, departed over the next 15 days.

10 February

VC sappers blew up a hotel used as an enlisted men's barracks in Qui Nhơn, killing 23 U.S. soldiers, two VC sappers and seven civilians.[22]

11 February

In response to the Qui Nhơn attack President Johnson ordered Operation Flaming Dart II: 155 sorties and air strikes by U.S. and RVNAF aircraft.[14]^:58–9

In Hanoi, Soviet Premier Kosygin announced the Soviet Union had agreed to assist North Vietnam to defend itself from air attacks, by providing surface-to-air missiles (SAMs), jet fighter planes, technical support and advisers.[23]

On his way back to Moscow from Hanoi, Kosygin stopped in Beijing for the second time in less than a month, and met with Mao Zedong, with a suggestion that the two nations help the United States to "find a way out of Vietnam" that would end the continuing war there; Mao's response was a warning that the Soviets should not use Vietnam as a bargaining issue in negotiations with the U.S., and refused to agree.[24]

13 February

President Johnson approved Operation Rolling Thunder, the Joint Chiefs of Staff plan for the sustained bombing of North Vietnam. Over an eight-week period, U.S. warplanes planned to bomb fixed targets and interdict military traffic along roads in southern North Vietnam. Johnson did not immediately launch Rolling Thunder.[5]^:333–4

16 February

Weapons and munitions captured at Vung Ro Bay

In the Vung Ro Bay Incident, an American pilot spotted a 100-ton North Vietnamese naval trawler unloading munitions on a beach at a remote bay on the coast of central South Vietnam. RVNAF aircraft sank the ship and the defenders and crew were later killed or captured after a firefight with South Vietnamese naval commandos. The incident spurred further United States Navy involvement in the Vietnam War.

The Armed Forces Council of South Vietnam appointed medical doctor Phan Huy Quát as Prime Minister.[6]^:363

Radio Moscow, the official English-language broadcasting station of the Soviet Union, warned that American bombing raids on North Vietnam could lead to a world war. "The flames of war starting in one place could easily spread to neighboring countries and, in the final count, embrace the whole world", the broadcast noted, and admonished that "responsibility for the dire consequences of such a policy rests with America."[25]

17 February

On the United States Senate floor, Senator Frank Church said "The Saigon government is losing its war, not for lack of equipment, but for lack of internal cohesion" and the best solution would be the negotiation of a neutral South Vietnam. Church's speech was supported by several other prominent Democratic Party Senators, including George McGovern. Church's call for a neutral South Vietnam echoed similar statements by French President Charles de Gaulle, the Pope and the Secretary General of the United Nations. Former President Eisenhower and several Republicans supported Johnson's policy. Eisenhower advised Johnson not to negotiate from weakness.[5]^:333–50

18 February

Influential columnist Walter Lippman in The Washington Post said escalation of the war would be a disaster. "For this country to involve itself in such a war in Asia would be an act of supreme folly."[5]^:351–2

19 February

Colonel Phạm Ngọc Thảo and General Lam Van Phat mounted a coup d'état to overthrow General Khánh, head of the Armed Forces Council. The coup failed but the instability forced Khanh from power. North Vietnam later revealed that Thao was a communist agent.[6]^:307[26]^:325 The coup collapsed when the U.S., in collaboration with Generals Nguyễn Chánh Thi and Cao Văn Viên, assembled units hostile to both Khanh and the current coup into a Capital Liberation Force.[27]^:302 Saigon was recaptured "without a shot" the next day by loyal troops and Khanh was restored to power[28]

21 February

The 15 generals comprising South Vietnam's High National Council — Nguyễn Văn Thiệu, Nguyen Van Cao and Nguyễn Cao Kỳ — voted to remove General Khánh from leadership as Prime Minister, and replaced him with a caretaker civilian premier, Trần Văn Hương.[29]

22 February

General Westmoreland requested that two battalions of United States Marines be assigned to protect Da Nang Air Base from the increasing threat of attacks by the VC.[17]^:7

25 February

General Khánh departed South Vietnam. He was persuaded to leave by his fellow generals and by Colonel Wilson of MACV. Air Marshall Kỳ became the de facto leader of South Vietnam.[6]^:364[5]^:362

26 February

The initial South Korean forces arrive in South Vietnam

The first South Korean troops arrived in South Vietnam in a brigade group known as Dove Force. These included engineers, a medical unit, military police, a navy LST, liaison staff, and other support personnel. Dove Force was deployed to Biên Hòa and helped build schools, roads and bridges. Medical teams are reported to have treated over 30,000 South Vietnamese civilians. The civilian operations in the early southern part of the campaign are reported to have had some success.[30][31]^:122–4

27 February

The U.S. Department of State issued a white paper to the press, Aggression From the North: The Record of North Viet-Nam's Campaign to Conquer South Viet-Nam, as a part of the U.S. government's effort to justify the escalation of the role of the U.S. in the war.[32] As a CIA employee and National Security Council staffmember would note later, the paper "proved to be a dismal disappointment... the only hard information we had about North Vietnamese participation and supplies and so forth came from information that was much too highly classified to include, and the only information that was of sufficiently low classification was pretty thin gruel."[33]^:127

28 February

The U.S. and South Vietnam announced that sustained bombing of North Vietnam would begin during the coming week. As a result of the announcement, North Vietnam's leaders ordered the evacuation of children and elderly residents from Hanoi and other major cities.[34]

1 March

Ambassador Taylor met with generals Thiệu and Trần Văn Minh in Saigon to request permission for the assignment of the Marines to Da Nang Air Base. The generals raised no objections, but asked that the Marines arrive "in the most inconspicuous way feasible."[17]^:9

2 March

Operation Rolling Thunder was launched. One hundred and four U.S. fighter-bombers and 19 RVNAF aircraft hit targets in the largest U.S. bombing raid to date against North Vietnam. Five U.S. planes and one RVNAF plane were shot down. The operation was meant to last eight weeks, but instead lasted more than three years.[35]^:408[12]^:234

Previously, North Vietnam and its allies China and the Soviet Union had indicated a willingness for negotiations leading to the neutralization of South Vietnam and the withdrawal of the U.S. The bombing resulted in a hardened and less flexible communist position. North Vietnam shut down channels it had with Canada and France for exploring negotiations.[5]^:366–7

4 March

An angry mob assembled outside the U.S. Embassy in Moscow to protest the bombing of North Vietnam, before finally being driven away by police on horseback and soldiers.[36] The next day, the Soviet Union formally apologized to the U.S. government and began replacement of 310 broken windows in the embassy building and the removal of stains from more than 200 inkpots that had been shattered against the walls.[37]

6 March

McGeorge Bundy wrote a memo to President Johnson saying: "Last night, Bob McNamara said for the first time what many others have thought for a long time - that the Pentagon and the military have been going at this thing the wrong way round from the very beginning: they have been concentrating on military results against guerrillas in the field, when they should have been concentrating on intense police control from the individual villager on up."[38]^:413–4

8 March

9th Marine Expeditionary Brigade comes ashore at Da Nang

1,400 Marines of the U.S. 9th Marine Expeditionary Brigade began to land on beaches near Da Nang. The arrival of the Marines heralded the direct involvement of American combat units in the war. The Marines had the responsibility of guarding the Da Nang Air Base but were ordered to "not, repeat not, engage in day-to-day actions against the Viet Cong." By the end of March the Marines at Da Nang numbered almost 5,000[17]^:11–6 Although there were 23,000 American military personnel in South Vietnam already, the deployment represented "the first body of Americans to go to the embattled southeast Asian nation as a fighting military unit."[39]

10 March

In Washington, Assistant Secretary of Defense John McNaughton sent a memo to National Security Adviser McGeorge Bundy outlining the U.S. objectives in South Vietnam in percentage terms: "70% - to avoid a humiliating US defeat...; 20% - to keep SVN [South Vietnam]...territory from Chinese hands; 10% - to permit the people of SVN to enjoy a better, freer way of life.[12]^:236–7

The first drawings were held under Australia's new birthday lottery system of conscription. At the Department of Labor and National Service in Melbourne, Representative Dan Mackinnon drew marbles from a barrel as part of the "birthday ballot" until there were sufficient eligible men to meet the quota of 4,200 draftees. The results were kept secret, with a policy that "Although pressmen will be able to watch and photograph the drawing of the first marble they will not be allowed to see or photograph the number on it." Young men whose birthdays were selected were "balloted out" and would be notified within four weeks.[40]

An SP-5B Marlin conducts a Market Time patrol

Operation Market Time, a U.S. Navy operation began off of the coast of North and South Vietnam with patrols along the coast and out to 150 miles (240 km) offshore, in order to disrupt North Vietnam's supply lines to the PAVN/VC in the south.[41]

12 March

Vice President of the United States Hubert Humphrey had dinner with the Ambassador of the Soviet Union Anatoly Dobrynin in Washington. Dobrynin asked why the U.S. bombed North Vietnam while the USSR Premier Kosygin was visiting Hanoi. Dobrynin advised that the USSR was now committed to the support of North Vietnam, saying "We can't be a leader and stand by and ignore the bombing of the North Vietnamese."[42]

16 March

82-year old Alice Herz stood at the corner of Grand River Avenue and Oakman Boulevard in Detroit, doused herself with two cans of flammable cleaning fluid, then set herself ablaze in protest against the war.[43] She left a note that said, "I choose the illuminating death of a Buddhist to protest against a great country trying to wipe out a small country for no reason." Two bystanders smothered the flames, but she died of her burns 10 days later.[44]

17 March

The CIA and Defense Intelligence Agency issued an estimate of military strength in South Vietnam. The armed forces of South Vietnam numbered 567,000, of which 245,000 belonged to the ARVN and the remainder to the Regional and Popular Force militia. The VC was estimated to number between 50,000 and 60,000 regulars and 100,000 militia.[45]^:143

20 March

After hearing from General Harold K. Johnson, the U.S. Army Chief of Staff, that it would take five years of fighting and 500,000 American troops to win the war, the Joint Chiefs of Staff recommended to Secretary McNamara to change the American mission from being "not simply to withstand the Viet Cong... but to gain effective operational superiority and assume the offensive", and that two additional divisions of combat troops be transferred to South Vietnam for that purpose. "To turn the tide of war," the memo said, "requires an objective of destroying the Viet Cong, not merely to keep pace with them, or slow their rate of advance."[33]^:174–5

22 March

Quoting Associated Press (AP) photographer Horst Faas and unidentified sources, AP reporter Peter Arnett broke the story that U.S. and South Vietnamese forces were using gas warfare in combat. Though he emphasized that these were "non-lethal" gases dispensed by helicopters and bombers, Arnett wrote that "one gas reportedly causes extreme nausea and vomiting, another loosens the bowels".[46] Hours after the story was revealed, a spokesman for the U.S. Department of Defense confirmed for afternoon papers that the story of the use of gas, but said that it was only being used by "South Vietnam's armed forces".[47] Two days later, U.S. Secretary of State Rusk would hold a press conference to respond to the controversy, saying "We are not embarking upon gas warfare in Vietnam. There has been no policy decision to engage in gas warfare in Vietnam. We are not talking about agents or weapons that are associated with gas warfare... We are not talking about gas that is prohibited by the Geneva Convention of 1925."[48]

24–25 March

The first Teach-in to protest the war was held at the University of Michigan, 3,500 people attended.[49][50]

25 March

China announced that it was ready to "send its personnel to fight together with the Vietnamese people to annihilate the American aggressors."[51]

26 March

General Westmoreland, said in a report to Washington that the South Vietnamese armed forces had "begun to show evidence of fragmentation and there is no longer an effective chain of command."[52]

29 March

In the face of disagreement among U.S. military leaders about where and how many U.S. combat troops should be stationed in Vietnam, Secretary McNamara, General Westmoreland, Ambassador Taylor and the Joint Chiefs met in Washington. The Chiefs and Westmoreland wanted two U.S. combat divisions sent to Vietnam along with one combat division from the Republic of Korea. Taylor disagreed. McNamara didn't take a position. In meetings the next day, President Johnson agreed only to the assignment of two additional U.S. combat battalions to South Vietnam, but he approved an expansion and extension of the bombing of North Vietnam under Operation Rolling Thunder.[45]^:145–6

After a three-year testing period that had started with the beginning of Operation Ranch Hand on 29 December 1961, the United States moved into the second phase of the operation with the heavy use of defoliants and herbicides in combat zones. Initially, four tactical herbicides, codenamed Purple, Pink, Green and Blue, were used, with Purple, a combination of 2,4-Dichlorophenoxyacetic acid (2,4-D) and 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) being the used the most.[53]

The Soviet Union and the People's Republic of China signed an agreement allowing Soviet trains to travel through China to deliver economic and military aid to North Vietnam. However Mao Zedong rejected a request by Soviet leader Leonid Brezhnev to allow Soviets overflights through an air corridor for shipments.[55]

The RAND Corporation publishes its first report on the war: Viet Cong Motivation and Morale in 1964 A Preliminary Report based on interviews with 145 VC POWs defectors and suspects between July and December 1964.[56]

In North Vietnam President Ho Chi Minh decreed a new military service law. Enlistments were extended indefinitely for soldiers, previously discharged soldiers were recalled, and an increased number of young people were inducted into military service. During 1965, North Vietnam expanded the size of its army by 290,000 personnel and its self-defense militia from 1.4 million to 2.0 million.[57]^:164

1 April

President Johnson authorized a change in the U.S. Marines' mission in South Vietnam, a month after the first units had been sent to protect installations at Da Nang from attack. For the first time, American ground troops were scheduled to move into the surrounding area and to engage PAVN/VC forces in combat.[58]

3 April

The first jet-to-jet combat of the war took place when four U.S. Navy F-8E Crusaders from the USS Hancock were engaged by eight Vietnam People's Air Force (VPAF) MiG-17 fighters from the 921st Sao Do Regiment. One of the F-8Es was set on fire by cannons fired from a MiG-17 but was able to land safely at Da Nang.[59] The VPAF claim to have shot down two F-8Es.[57]^:166 In future years, 3 April would be a Vietnamese public holiday commemorated as "Air Force Day."[60]

Operation Steel Tiger was a covert United States Air Force (USAF) 2nd Air Division, later Seventh Air Force and U.S. Navy Task Force 77 aerial interdiction effort targeted against the Ho Chi Minh Trail in southeastern Laos.[61]^:53

4 April

The USAF conducted its first airstrike on the Thanh Hóa Bridge, the raid failed to down the bridge and it would resist further attacks until finally being downed on 13 May 1972. Two USAF F-105 Thunderchief strike aircraft were shot down and both their pilots killed, the first aircraft lost in air-to-air combat by either side during the war.[62] A USAF F-100 Super Sabre fighter escorting the strike aircraft scored the first probable USAF kill of the war shooting down a VPAF MiG-17.[63]

5 April

A North Vietnamese SA-2 site

A U.S. Navy RF-8 Crusader reconnaissance aircraft photographed an SA-2 Guideline surface-to-air missile (SAM) site under construction in North Vietnam for the first time. The discovery, 15 miles (24 km) southeast of Hanoi, "sent shivers down the spines of task force commanders and line aviators alike", a historian would note later, but official permission to attack a site so close to the capital would not be given "until the Navy and Air Force lost a few jets to the SA-2s".[64]

7 April

President Johnson made a major televised speech at Johns Hopkins University. Johnson described the war as an attack by North Vietnam on South Vietnam. He proposed "unconditional discussions" to exchange views with interested parties in search of a peaceful solution, but offered no concessions. Johnson also proposed a massive program to develop the Mekong River basin which could include North Vietnam among the recipients of the Tennessee Valley Authority-type project. Ho Chi Minh responded that the United States must withdraw from South Vietnam as a condition for a peace agreement.[38]^:423–6 The Johns Hopkins speech marked a change in American policy. Formerly, over a period of several years of escalating warfare in South Vietnam, the U.S. had refused to consider talking to the VC and North Vietnamese until the U.S. and South Vietnam had gained a military advantage.[38]^:421

Elements of the VC 2nd Regiment attacked the positions of the 2nd Vietnamese Marine Battalion at midnight. The Marines repulsed 10 attacks and the VC withdrew at dawn leaving 59 dead, 10 wounded and 71 weapons. Intelligence revealed that a further 70 VC dead and over 200 wounded were removed from the battlefield; VNMC losses were four killed.[17]^:206

8 April

North Vietnamese Prime Minister Phạm Văn Đồng responded to President Johnson's proposal for peace negotiations by announcing North Vietnam's Four Points peace formula: withdrawal of all U.S. forces from South Vietnam, neutralization of both Vietnams pending reunification, adoption of the program of the National Liberation Front [VC] for internal affairs, and reunification without foreign interference.[65]^:25

A mutiny by 20 young officers ousted Admiral Chung Tấn Cang as commander of the Republic of Vietnam Navy in an action "that evidently had the government's blessing". The military junta governing South Vietnam did not order a response, and one U.S. official commented that Cang, an associate of recently ousted President Nguyen Khanh, "has been a thorn in our side", because of his lack of cooperation in moving military supplies.[66]

Two U.S. Navy F-4B Phantom fighters flew into Chinese airspace and were tracked by radar flying over the Yulin Naval Base on Hainan Island, but departed before the Chinese military could respond to an alert.[67]

9 April

At a CINCPAC meeting in Hawaii, the planners recommended the deployment of two brigades to South Vietnam. One would be stationed at Biên Hòa near Saigon to protect Bien Hoa Air Base; the other would go to Nha Trang to prepare for the introduction of a full division of U.S. troops. Ambassador Taylor had not been present at the meeting and he protested that "Recent actions relating to the introduction of U.S. ground forces have tended to create an eagerness in some quarters to deploy forces into SVN which I find difficult to understand." Taylor opposed the introduction of American ground troops for offensive operations, believing they should be restricted to coastal "enclaves." General Westmoreland disagreed, believing that enclaves were "an inglorious, static use of U.S. forces....that would leave the decision of when and where to strike to the enemy."[45]^:140–9

Two groups of four U.S. Navy F-4Bs, flew over Hainan Island. This time, a squadron of four Jian-5 jet fighters from the People's Liberation Army Air Force (PLAAF) intercepted them, with instructions not to fire unless fired upon. The American pilots stated that they had believed that they were outside China's airspace and in an area 36 miles (58 km) southwest of Hainan, while China accused the U.S. of trying to provoke a war.[67]

14 April

The U.S. and South Vietnam began "Operation Fact Sheet", a psychological warfare aerial mission, dropping over two million notices on those cities in North Vietnam with military facilities. The paper leaflets carried different types of messages written in the Vietnamese language. Some of them warned civilians to stay away from the areas that were to be bombed, and others suggested that civilians "could end the bombings by turning against their government", or advocated the benefits of moving to South Vietnam. During April, May and June, nearly 25 million papers were dropped. "The leaflets had no effect on North Vietnamese strategy", an author would note later, "but they did result in a few civilians moving away from military facilities."[68]

16 April

Life magazine publishes as its cover story the photo-essay "One ride with Yankee Papa 13" by Larry Burrows documenting a helicopter mission on 31 March.[69]

17 April

In Washington, D.C. about 20,000 people gathered to protest the war organized by the Students for a Democratic Society (SDS). This was the first large protest against the war in the United States.[70] At the same time, a counter-protest of about 100 people took place across the street, and a group of students representing the University of Wisconsin presented National Security Adviser McGeorge Bundy with a petition of support for the war, signed by 6,000 faculty and students.[71]

China rescinded the order to the PLAAF to not attack American war planes violating Chinese air space. Over the next three years, 12 American war planes and several reconnaissance planes were shot down over China.[72]

20 April

At a meeting of American military and political leaders in Honolulu, Ambassador Taylor successfully proposed that the U.S. adopt what he called the "enclave strategy" in its conduct of the war. Defense Secretary McNamara and Assistant Secretary John McNaughton, CIA analyst William Bundy, General Westmoreland, U.S. Navy Admiral U. S. Grant Sharp Jr. and the Joint Chiefs of Staff Chairman, General Earle Wheeler concurred in the proposal, which was adopted by President Johnson. Taylor's idea was to limit U.S. ground operations to within a 50 miles (80 km) radius of important areas in important coastal areas, and with the ARVN to conduct counter-insurgency operations in the surrounding territory. The strategy would prove unsuccessful, leading to Taylor's resignation and a switch to a "search and destroy" operation in June.[73] In a memo to the President the next day, McNamara described the military consensus that "it would take more than six months, perhaps a year or two to...break the will of the DRV/VC [PAVN/VC] by denying them victory." On this date the U.S. had 33,000 U.S. military personnel in Vietnam and another 20,000 scheduled to be there.[74]^:212

22 April

Defense Secretary McNamara told reporters that he would not rule out the use of nuclear weapons in the war, as part of a press conference given under the condition that the reporters not attribute his remarks to him, nor quote him verbatim. Tom Wicker of The New York Times took notes and paraphrased the statement, in which McNamara said "We are not following a strategy that recognizes any sanctuary or any weapons restriction. But we would use nuclear weapons only after fully applying non-nuclear arsenal. In other words, if 100 planes couldn't take out a target... we would try 200 planes, and so on. But 'inhibitions' on using nuclear weapons are not overwhelming." Wicker's report noted that "High officials" in the Johnson administration "emphasize that it is 'inconceivable' that nuclear weapons would be used in the present circumstances of the war. They do not rule out the possibility that circumstances might arise in which nuclear weapons have to be used."[75] Nikolai T. Fedorenko, the Soviet Ambassador to the United Nations, sharply criticized McNamara and the U.S. in a speech the day after the report, commenting that "See the statement made today by Mr. McNamara... The United States is not averse to utilizing — this time perhaps as tactical weapons - nuclear warheads against the people of an Asian country as they have done once before, covering themselves with indelible shame for centuries to come. Mr. McNamara clearly reserved the right to unleash nuclear war in Vietnam."[76]

"While Berkeley police photographers snapped their photos," an Associated Press report noted, "the students squatted in a huddle like a football team and placed their burning cards in a small pile." Although future draft-card burnings would be made in opposition to the war, the initial protest was against the U.S. intervention in the Dominican Civil War.[87]

President Johnson convened his advisers in a meeting of the 15 member National Security Council at the White House, prior to making a decision about the direction that the United States should take in fighting the war. During the morning session, George Ball, the United States Under Secretary of State strongly argued against the recommendation by Secretary of Defense McNamara to increase the number of American troops in South Vietnam. According to minutes of that day's meeting that would be released years later, Ball urged that the U.S. should "cut its losses" and allow the South Vietnamese government to "do what seems natural to it, let it fall apart" and, with the rest of the advisers against him, closed with the prophetic statement that South Vietnam would ultimately lose to the VC guerrillas, regardless of McNamara's plans to commit 175,000 additional troops, that the U.S. would not get out with a victory, and that "we'll double our bet and get lost in the rice paddies."[117] In the course of the discussion, General Wallace M. Greene, Jr. estimated that winning the war would take 5 years and 500,000 American soldiers. He said that he believed the American people would back such a commitment. Johnson was skeptical that Americans would support such a large commitment and opted instead for a gradual buildup of American forces and escalation of the war as recommended by General Westmoreland.[118]
