This attack sparked a ten-day battle that drew in elements of the U.S. 1st Infantry Division and the ARVN 18th Division and left 800 PAVN troops dead at its conclusion. The most severe of what came to be known as "the Border Battles" erupted during October and November around Dak To , another border outpost in Kon Tum Province . The clashes there between
375-567: A U.S. bombing raid on COSVN after having been evacuated from Cambodia. After cementing their position during the Party crackdown, the militants sped up planning for a major conventional offensive to break the military deadlock. They concluded that the Saigon government and the U.S. presence were so unpopular with the population of the South that a broad-based attack would spark a spontaneous uprising of
500-449: A compromise: The CIA would drop its insistence on including the irregulars in the final tally of forces and add a prose addendum to the estimate that would explain the agency's position. George Allen, Carver's deputy, laid responsibility for the agency's capitulation at the feet of Richard Helms , the director of the CIA. He believed that "it was a political problem ... [Helms] didn't want
625-615: A conventional conflict might draw China in, as had happened in the Korean War . They also resisted the idea of negotiating with the allies. Moscow, on the other hand, advocated negotiations, but simultaneously armed Hanoi's forces to conduct a conventional war on the Soviet model. North Vietnamese foreign policy therefore consisted of maintaining a critical balance between war policy, internal and external policies, domestic adversaries, and foreign allies with "self-serving agendas." To "break
750-609: A countrywide assault on the cities, conducted primarily by VC forces. Concurrently, a propaganda offensive to induce ARVN troops to desert and the South Vietnamese population to rise up against the government would be launched. If outright victory was not achieved, the battle might still lead to the creation of a coalition government and the withdrawal of the Americans. If the general offensive failed to achieve these purposes, follow-up operations would be conducted to wear down
875-406: A dawning realization that if current trends continued, Hanoi would eventually lack the resources necessary to affect the military situation in the South. As a result, there were more strident calls by the moderates for negotiations and a revision of strategy. They felt that a return to guerrilla tactics was more appropriate since the U.S. could not be defeated conventionally. They also complained that
1000-668: A major North Vietnamese military buildup. In addition to captured documents (a copy of Resolution 13 , for example, was captured by early October), observations of enemy logistical operations were also quite clear: in October, the number of trucks observed heading south through Laos on the Hồ Chí Minh Trail jumped from the previous monthly average of 480 to 1,116. By November this total reached 3,823 and, in December, 6,315. On 20 December, Westmoreland cabled Washington that he expected
1125-493: A massive conventional military operation that was being conducted on three fronts simultaneously, involving the equivalent of 15 divisions and 600 tanks. As the North Vietnamese continued to gain ground in three of South Vietnam's four military regions, the U.S. Joint Chiefs of Staff updated their contingency plans (drawn up before the bombing halt of 1968) for the resumption of bombing in the north and recommended it to
1250-733: A mining operation since 1965. On 5 May, Nixon ordered the Joint Chiefs to prepare to execute the aerial mining portion of the Duck Hook plan within three days under the operational title Pocket Money . At precisely 09:00 (local time) on 9 May, six US Navy A-7 Corsair IIs and three A-6 Intruders from the USS Coral Sea flew into Haiphong harbor and dropped thirty-six 1,000-pound (450 kg) Mark-52 and Mark-55 naval mines into its waters. They were protected from attacks by Vietnam People's Air Force (VPAF) MiG fighter aircraft by
1375-551: A month over two rail lines and eight major roads that linked it with North Vietnam. On 10 May Operation Linebacker began with mass bombing operations against North Vietnam by tactical fighter aircraft of the Seventh Air Force and Task Force 77. Their targets included the railroad switching yards at Yên Viên and the Paul Doumer Bridge, on the northern outskirts of Hanoi. A total of 414 sorties were flown on

#17327795918011500-496: A more comprehensive bombing campaign which would include strikes against both Hanoi and Haiphong. The following day 18 B-52s struck Thanh Hóa 's Bai Thuong Air Base . Three more days followed before another strike, this time by another 18 bombers in a pre-dawn attack against an oil tank farm outside Haiphong. They were followed by more than 100 tactical aircraft attacking targets around Hanoi and Haiphong during daylight. Between 6 and 15 April, U.S. aircraft also struck and destroyed
1625-423: A preliminary phase, during which diversionary attacks would be launched in the border areas of South Vietnam to draw American attention and forces away from the cities. The general offensive and uprising would then commence with simultaneous actions on major allied bases and most urban areas, and with particular emphasis on the cities of Saigon and Huế. Concurrently, a substantial threat would have to be made against
1750-419: A protracted war of attrition". In May, MACV attempted to obtain a compromise from the CIA by maintaining that VC militias did not constitute a fighting force but were essentially low-level fifth columnists used for information collection. With the groups deadlocked, George Carver, CIA Special Assistant for Vietnam Affairs, represented the CIA in the last stage of the negotiations. In September, Carver devised
1875-674: A rapid build-up of airpower. The USAF deployed 176 F-4s and 12 F-105 Thunderchiefs from bases in the Republic of Korea and the U.S. to Thailand between 1 April and 11 May in Operation Constant Guard. Strategic Air Command (SAC) dispatched 124 B-52s from the U.S. to Guam bringing the total B-52 strength available for operations to 209. The USN cut short its port period for the carriers USS Kitty Hawk and USS Constellation and ordered USS Midway , USS America and USS Saratoga to augment
2000-611: A series of coups had characterized the preceding years. Protests, campaigning and the atmosphere of elections were interpreted by the Politburo of the Communist Party of Vietnam and Lê Duẩn as signs that the population would embrace a 'general uprising' against the government of South Vietnam. The Politburo sought to exploit perceived instability and maintain political weakness in South Vietnam. During late 1967,
2125-638: A total of 76 aircraft, stationed in South Vietnam. Another 114 fighter-bombers were located at bases in Thailand . 83 B-52s were stationed at U-Tapao RTAFB , Thailand and at Andersen Air Force Base , Guam . The U.S. Navy (USN)'s Task Force 77 (stationed in the Gulf of Tonkin ), had four aircraft carriers assigned to it, but only two were available at any one time to conduct operations. Their air wings had approximately 140 aircraft. American and Republic of Vietnam Air Force (RVNAF) aircraft had been supporting
2250-510: A twelve-day period between 24 June and 5 July. USAF pilots were hampered by use of the outdated "fluid four" tactical formations (a four-plane, two element formation in which only the leader did the shooting and in which the outside wingmen were vulnerable) dictated by service doctrine. Also contributing to the parity was a lack of air combat training against dissimilar aircraft, a deficient early warning system, and ECM pod formations that mandated strict adherence to formation flying. During August
2375-529: A very public debate over military strategy took place in print and via radio between Thanh and his rival for military power, Giáp. Giáp had advocated a defensive, primarily guerrilla strategy against the U.S. and South Vietnam. Thanh's position was that Giáp and his adherents were centered on their experiences during the First Indochina War and that they were too "conservative and captive to old methods and past experience... mechanically repeating
2500-448: A winter-spring offensive during 1968 had begun in early 1967 and continued until early the following year. According to American sources, there has been an extreme reluctance among Vietnamese historians to discuss the decision-making process that led to the general offensive and uprising , even decades after the event. In official Vietnamese literature, the decision to launch the Tet offensive
2625-415: Is at hand." This once again placed Hanoi and Haiphong off-limits, and halted Linebacker operations. Air Force historian Earl Tilford has written that Linebacker was "a watershed in aerial warfare...it was the first modern aerial campaign in which precision guided munitions changed the way in which air power was used." It succeeded, where Rolling Thunder had failed, he claimed, for three reasons: Nixon

The purpose of the wide-scale offensive by the Hanoi Politburo was to trigger political instability in a belief that mass armed assault on urban centers would trigger defections and rebellions . The offensive was launched prematurely in
2875-407: The 1967 South Vietnamese presidential election , looked increasingly stable. Rivalries between South Vietnam's generals were becoming less chaotic, and Thiệu and Kỳ formed a joint ticket for the election. Despite efforts by North Vietnam to disrupt elections, higher than usual turnouts saw a political turning point towards a more democratic structure and ushered in a period of political stability after
3000-521: The Demilitarized Zone (DMZ). The intense shelling (100–150 rounds per day) prompted Westmoreland to launch Operation Neutralize , an intense aerial bombardment campaign of 4,000 sorties into and just north of the DMZ. On 27 October, an ARVN battalion at Sông Bé , the capital of Phước Long Province , came under attack by an entire PAVN regiment. Two days later, another PAVN regiment attacked

Begun 19 May 1964 as medium and low level U.S. Navy photo reconnaissance missions over the Plain of Jars , it was soon ramped up to "armed reconnaissance" covered by U.S. Air Force F-100 Super Sabre fighter escorts from Tan Son Nhut . The classified operation was dubbed Yankee Team on 25 May 1964. Notice of their non-emergency sorties was forwarded from CINCPAC to Washington 36 hours in advance for possible cancellation. A command post
3250-736: The Paul Doumer and Thanh Hóa bridges and the Yên Viên railway marshalling yard . This marked the introduction of laser-guided bombs against strategic targets in North Vietnam. Both bridges had previously been attacked unsuccessfully with conventional bombs and even missiles. The B-52s were then withdrawn from operations in the north and when they returned in June, their missions would be limited to South Vietnam. By mid-month, nearly all of North Vietnam had been cleared for bombing raids for

This group was led by Communist Party First Secretary Lê Duẩn and Lê Đức Thọ (no relation). From the early to mid-1960s, the militants had dictated the direction of the war in South Vietnam. General Nguyễn Chí Thanh , the head of Central Office for South Vietnam (COSVN), headquarters for

Concessions had been made to the center group, however, by agreeing that negotiations were possible, but the document essentially centered on the creation of "a spontaneous uprising in order to win a decisive victory in the shortest time possible." Contrary to Western belief, Giáp did not plan or command
3625-503: The American operation, they were not willing to jeopardize their thawing relationship with the U.S. and Hanoi's requests for support and aid from its socialist allies met with only cool responses. Operation Linebacker, the code name for the new interdiction campaign, would have four objectives: to isolate North Vietnam from its sources of supply by destroying railroad bridges and rolling stock in and around Hanoi and north-eastwards toward
3750-526: The American public still disapproved of the President's handling of the war. The American public, "more confused than convinced, more doubtful than despairing ... adopted a 'wait and see' attitude." During a discussion with an interviewer from Time magazine, Westmoreland dared the communists to launch an attack: "I hope they try something because we are looking for a fight." Planning in Hanoi for

There was a discrepancy, however, between the order of battle estimates of the MACV and the Central Intelligence Agency (CIA) concerning the strength of VC guerrilla forces within South Vietnam. In September, members of the MACV intelligence services and the CIA met to prepare a Special National Intelligence Estimate that would be used by the administration to gauge U.S. success in

4000-644: The Chinese frontier; the targeting of primary storage areas and marshalling yards; to destroy storage and transshipment points and to eliminate (or at least damage) the North's air defense system. With nearly 85 percent of North Vietnam's imports (which arrived by sea) blocked by Pocket Money , the administration and the Pentagon believed that this would cut its final lines of communication with its socialist allies. China alone shipped an average of 22,000 tons of supplies
4125-456: The Communist Party militants. For the moderates and centrists, it offered the prospect of negotiations and a possible end to the American bombing of the North. Only in the eyes of the militants, therefore, did the offensive become a "go for broke" effort. Others in the Politburo were willing to settle for a much less ambitious "victory". The PAVN official history states that the objectives of

Leading up to the Tet Offensive were years of marked political instability and a series of coups after the 1963 South Vietnamese coup . In 1966,
4375-409: The North Vietnamese had done was carry out the first stage of their plan: to fix the attention of the U.S. command on the borders and draw the bulk of U.S. forces away from the heavily populated coastal lowlands and cities. Westmoreland was more concerned with the situation at Khe Sanh, where, on 21 January 1968, a force estimated at 20,000–40,000 PAVN troops had besieged the U.S. Marine garrison. MACV
4500-531: The PAVN/VC "to undertake an intensified countrywide effort, perhaps a maximum effort, over a relatively short period of time." Despite all the warning signs, however, the allies were still surprised by the scale and scope of the offensive. According to ARVN Colonel Hoang Ngoc Lung the answer lay with the allied intelligence methodology itself, which tended to estimate the enemy's probable course of action based upon their capabilities, not their intentions. Since, in
4625-520: The President, who approved it on 8 May. Shortly after his inauguration, Nixon had ordered the preparation of a contingency plan, one that would hopefully bring the Vietnam War to an end. Operation Duck Hook was to include an invasion of the North and included a proposal to mine its major harbors. The plan had been shelved at the time as too extreme but it had not been forgotten. The USN had also been updating its own contingency plans for just such
4750-402: The South, was another prominent militant. The followers of the Chinese line centered their strategy against the U.S. and its allies on large-scale, main force actions rather than the protracted guerrilla war espoused by Mao Zedong . By 1966–1967, however, after suffering massive casualties, stalemate on the battlefield, and destruction of the northern economy by U.S. aerial bombing , there was
4875-496: The Soviet and Chinese reaction to the escalation. Hours before Nixon's speech announcing the mining, Kissinger had delivered a letter to Soviet ambassador Anatoly Dobrynin which outlined the U.S. plan, but which also made clear Nixon's willingness to proceed with the summit. The next day, Nixon shook the hand of Soviet Foreign Trade Minister Nikolai Patolichev at the White House . Although Moscow and Beijing publicly denounced

Shortly before the 1968 United States presidential election , Republican candidate and former vice president Richard Nixon encouraged South Vietnamese President Nguyễn Văn Thiệu to become publicly uncooperative in the negotiations, casting doubt on Johnson's ability to bring peace. The term "Tet offensive" usually refers to

5250-491: The Thiệu government in the southern press. Launching such an offensive would also finally put an end to what had been described as "dovish calls for talks, criticism of military strategy, Chinese diatribes of Soviet perfidy, and Soviet pressure to negotiate—all of which needed to be silenced." In October, the Politburo decided on the Tet holiday as the launch date and met again in December to reaffirm its decision and formalize it at
5375-457: The U.S. Khe Sanh Combat Base . The Khe Sanh actions would draw PAVN forces away from the offensive into the cities, but Giáp considered them necessary to protect his supply lines and divert American attention. Attacks on other U.S. forces were of secondary, or even tertiary importance, since Giáp considered his main objective to be weakening or destroying the South Vietnamese military and government through popular revolt. The offensive, therefore,
5500-617: The U.S. command in Saigon was perplexed by a series of actions initiated by the PAVN/VC in the border regions. On 24 April a U.S. Marine Corps patrol prematurely triggered a PAVN offensive aimed at taking Khe Sanh Combat Base, the western anchor of the Marines' defensive positions in Quảng Trị Province . For 49 days during early September and lasting into October, the PAVN began shelling the U.S. Marine outpost of Con Thien , just south of
5625-593: The U.S. perspective was summed up by an MACV intelligence analyst: "If we'd gotten the whole battle plan, it wouldn't have been believed. It wouldn't have been credible to us." The Tet offensive would later be used in a textbook at West Point as an example of "an allied intelligence failure to rank with Pearl Harbor in 1941 or the Ardennes offensive in 1944."

To pave the way and to confuse the allies as to its intentions, Hanoi launched a diplomatic offensive. Foreign Minister Trinh announced on 30 December that Hanoi would rather than could open negotiations if the U.S. unconditionally ended Operation Rolling Thunder ,
5875-581: The VC. General Bruce Palmer Jr. , one of Westmoreland's three Field Force commanders, claimed that "the Viet Cong has been defeated" and that "He can't get food and he can't recruit. He has been forced to change his strategy from trying to control the people on the coast to try to survive in the mountains." Westmoreland was even more emphatic in his assertions. At an address at the National Press Club on 21 November, he reported that, as of

Every statistical indicator of progress, from "kill ratios" and "body counts" to village pacification,

During the second half of 1967 the administration had become alarmed by criticism, both inside and outside the government, and by reports of declining public support for its Vietnam policies. According to public opinion polls, the percentage of Americans who believed that the U.S. had made a mistake by sending troops to Vietnam had risen from 25 percent in 1965 to 45 percent by December 1967. This trend
6250-402: The allied estimation, the communists hardly had the capability to launch such an ambitious enterprise: "There was little possibility that the enemy could initiate a general offensive, regardless of his intentions." The answer could also be partially explained by the lack of coordination and cooperation between competing intelligence branches, both South Vietnamese and American. The situation from
6375-484: The allied intelligence collection apparatus in Saigon. During the late summer and fall of 1967 both South Vietnamese and U.S. intelligence agencies collected clues that indicated a significant shift in communist strategic planning. By mid-December, mounting evidence convinced many in Washington and Saigon that something big was underway. During the last three months of the year intelligence agencies had observed signs of

Around the American combat base at Khe Sanh , fighting continued for two more months. The offensive

On 5 April, a PAVN force of 20,000 crossed the border from their sanctuaries in Cambodia in another three-division, combined arms force to attack Bình Long Province , north of Saigon . They quickly seized the town of Lộc Ninh and then surrounded the town of An Lộc , cutting

During the same time period, the RVNAF lost ten aircraft. 63 VPAF aircraft were destroyed during the same time period. North Vietnam claimed that it had shot down 651 aircraft and sunk or set on fire 80 U.S. warships during
7000-676: The bombing campaign against North Vietnam. This announcement provoked a flurry of diplomatic activity (which amounted to nothing) during the last weeks of the year. South Vietnamese and U.S. military intelligence estimated that PAVN/VC forces in South Vietnam during January 1968 totaled 323,000 men, including 130,000 PAVN regulars, 160,000 VC and members of the infrastructure, and 33,000 service and support troops. They were organized into nine divisions composed of 35 infantry and 20 artillery or anti-aircraft artillery regiments, which were, in turn, composed of 230 infantry and six sapper battalions. Signs of impending communist action were noticed among

The first mass B-52 raid directed against the north was conducted on 10 April when 12 B-52s, supported by 53 attack aircraft, struck petroleum storage facilities around Vinh . By 12 April, Nixon had informed Kissinger that he had decided on
9250-559: The following month. Thanh was then ordered to the capital to explain his concept in person to the Military Central Commission. At a meeting in July, Thanh briefed the plan to the Politburo. On the evening of 6 July, after receiving permission to begin preparations for the offensive, Thanh attended a party and died of a heart attack after drinking too much. An alternative account is that Thanh died of injuries sustained in
9375-652: The formalization of the Strategic Arms Limitation Treaty ( SALT I ) with the Soviet Union , that was due to be signed in May. Another stumbling block to the plan was Abrams' desire to utilize the available bombers (with their all-weather capability) to support the ARVN defense. Nixon and Kissinger considered a plan offered by the Joint Chiefs of Staff to be both unimaginative and lacking in aggression. On 4 April, Nixon authorized
9500-592: The four northern provinces of South Vietnam and dropped 40,000 tons of ordnance in the Battle of An Lộc. Between March and May, B-52 sortie rates had climbed from 700 to 2,200 per month and they had dropped 57,000 tons of bombs in Quảng Trị Province alone. During Freedom Train and Linebacker proper, B-52s had dropped 150,237 tons of bombs on the North while Air Force and Navy tactical aircraft had flown 1,216 sorties and dropped another 5,000 tons of ordnance. From
9625-571: The four regiments of the PAVN 1st Division , the U.S. 4th Infantry Division , the 173rd Airborne Brigade and ARVN infantry and Airborne elements, lasted for 22 days. By the time the fighting was over, between 1,200 and 1,600 PAVN and 262 U.S. troops had been killed. MACV intelligence was confused by the possible motives of the North Vietnamese in prompting such large-scale actions in remote regions where U.S. artillery and aerial firepower could be applied indiscriminately, which meant that tactically and strategically, these operations made no sense. What
9750-426: The four torpedo boats were sunk. It was one of the few ship-to-ship naval battles of the war. The stalled offensive in the South and the devastation in North Vietnam had helped to convince Hanoi to return to the bargaining table by early August. The meetings produced new concessions from Hanoi which promised to end the deadlock that had plagued negotiations since their inception in 1968. Gone were Hanoi's demands for
9875-579: The geographic reference point "Y", pronounced "Yankee" in the NATO phonetic alphabet . In turn the term Point Yankee derived from the launch point for "Yankee Team" aerial reconnaissance missions over Laos conducted in 1964. The first ship operations at Point Yankee took place in April 1964. Starting 13 April 1966 Yankee Station was moved further toward the Gulf of Tonkin at 17° 30' N and 108° 30' E, about 190 km due east of Đồng Hới . Early missions were flown in
10000-414: The guided-missile cruisers Chicago and Long Beach , with several destroyers including the guided-missile destroyer USS Berkeley launching Operation Custom Tailor and by supporting flights of F-4 Phantoms. The reason for the precise timing of the strike became apparent when Nixon simultaneously delivered a televised speech explaining the escalation to the American people: "The only way to stop
10125-400: The heavy cruiser USS Newport News , the guided missile cruiser USS Providence , and the destroyers USS Robison and USS Rowan conducted a brief night raid against the North Vietnamese forces protecting the port of Haiphong. After the bombardment, the ships were threatened by four Soviet-built torpedo boats. Joined by two aircraft from the USS Coral Sea , three of
10250-706: The introduction of real-time early warning systems, increased aircrew combat experience and degraded VPAF ground control interception capabilities reversed the trend to a more favorable, with 4:1 kill ratio were claimed. During the operation, each side would ultimately claim favourable kill ratios. A total of 201 air battles took place between American and Vietnamese planes in 1972 sorties. The VPAF lost 47 MiGs (including 26 MiG-21s, 5 MiG-19s and 16 MiG-17s ) and they claimed 90 U.S. aircraft were shot down, including 74 F-4 fighters and two RF-4C (MiG-21s shot down 67 enemy aircraft, MiG-17s shot down 11 and MiG-19s shot down 12 enemy aircraft Linebacker saw several other "firsts". On
10375-470: The killing is to take the weapons of war out of the hands of the international outlaws of North Vietnam.". The mines were activated five days after their delivery to allow any vessels then in port to escape without damage. Over the next three days other US carrier-based aircraft laid 11,000 more mines into North Vietnam's secondary harbors, blockading all maritime commerce for the country. Before and during Pocket Money , Nixon and Kissinger had worried about
10500-534: The leadership in South Vietnam, represented by the Head of State Nguyễn Văn Thiệu and Prime Minister Nguyễn Cao Kỳ were persuaded to commit to democratic reforms in an effort to stabilize the political situation at a conference in Honolulu . Prior to 1967, the South Vietnamese constituent assembly was in the process of drafting a new constitution and eventual elections. The political situation in South Vietnam, after
10625-409: The line" (in combat) and statistical summaries were based on days on the line. Yankee Station was initially located at 16° 00′ N, 110° 00′ E, however with a massive increase in operations over North Vietnam in 1966 the station was moved about 145 miles (230 km) northwest to 17° 30′ N, 108° 30′ E, placing it about 90 miles (145 km) from the North Vietnamese shore. The name derived from it being
10750-574: The loss of 29 aircraft. The U.S. also now began what North Vietnamese historians have described as "using devious political and diplomatic schemes...to cut back the amount of aid being supplied to us by socialist nations". On 20 April Kissinger met secretly with Brezhnev in Moscow. Unwilling to jeopardize the normalisation of relations with the West and wary of Washington's growing relationship with Beijing , Brezhnev agreed to apply pressure to Hanoi to end
10875-477: The offensive and negotiate seriously. Brezhnev then arranged for another secret meeting between Kissinger and Hanoi's lead negotiator Le Duc Tho , to be held on 2 May in Paris. On the day, the two men met for a session that Kissinger later described as "brutal and insulting." The North Vietnamese, sensing victory, were in no mood to make concessions. As a result of this meeting and the fall of Quảng Trị City Nixon
11000-501: The offensive himself. Thanh's original plan was elaborated on by a party committee headed by Thanh's deputy, Phạm Hùng , and then modified by Giáp. The Defense Minister may have been convinced to toe the line by the arrest and imprisonment of most of the members of his staff during the Revisionist Anti-Communist Party Affair. Although Giáp went to work "reluctantly, under duress", he may have found
11125-537: The offensive was lackadaisical and confused. The Pentagon was not unduly alarmed and the U.S. Ambassador to South Vietnam and Commander, U.S. Military Assistance Command, Vietnam , General Creighton W. Abrams , were both out of the country. President Richard Nixon 's first response was to consider a three-day attack by Boeing B-52 Stratofortress heavy bombers on Hanoi and the port city of Haiphong . His National Security Advisor , Dr. Henry Kissinger , convinced Nixon to reconsider, since he did not want to jeopardize
11250-737: The opening day of the operation, USN Lieutenant Duke Cunningham and his radar intercept officer, Lieutenant (j.g.) William P. Driscoll became the first U.S. air aces of the Vietnam War when they shot down their fifth MiG. On 28 August, the USAF gained its first ace when Captain Richard S. Ritchie downed his fifth enemy aircraft. Twelve days later, Captain Charles B. DeBellevue (who had been Ritchie's backseater during four of his five victories) downed two more MiGs, bringing his total to six. On 13 October another weapons officer, Captain Jeffrey S. Feinstein ,
11375-422: The operation. Linebacker had played a crucial role in blunting the northern offensive by drying up its vital sources of supply. PAVN had evolved into a conventional military force, and such a force depended upon a complex logistical system, which made it vulnerable to aerial attack. By September, imports into North Vietnam were estimated at 35 to 50 percent below what they had been in May, bolstering claims that
11500-511: The ouster of South Vietnamese President Nguyễn Văn Thiệu and his replacement by a coalition government in which the Viet Cong would participate. The U.S. on its part agreed to a cease fire in place which conceded that PAVN soldiers could remain in South Vietnam after a peace agreement. The diplomatic impasse was broken and Nixon ordered a halt to all bombing above the 20th parallel on 23 October and on 26 October Kissinger announced that "peace
11625-517: The past." The arguments over domestic and military strategy also carried a foreign policy element, as North Vietnam, like South Vietnam, was largely dependent on outside military and economic aid. The vast majority of North Vietnam's military equipment was provided by either the Soviet Union or China. Beijing advocated that North Vietnam conduct a protracted war on the Maoist model, fearing that
11750-560: The policy of rejecting negotiations was in error. The Americans could only be worn down in a war of wills during a period of "fighting while talking". During 1967 things had become so bad on the battlefield that Lê Duẩn ordered Thanh to incorporate aspects of protracted guerrilla warfare into his strategy. During the same period, a counter-attack was launched by a new, third grouping (the centrists) led by President Hồ Chí Minh , Lê Đức Thọ, and Foreign Minister Nguyễn Duy Trinh , who called for negotiations. From October 1966 through April 1967,
11875-599: The population, which, if the offensive was successful, would enable the North Vietnamese to sweep to a quick, decisive victory. Their basis for this conclusion included: a belief that the South Vietnamese military was no longer combat-effective; the results of the 1967 presidential election (in which the Thiệu/Kỳ ticket had only received 24 percent of the popular vote); the Buddhist crises of 1963 and 1966 ; well-publicized anti-war demonstrations in Saigon; and continuous criticism of
12000-480: The position of the militants as Hanoi's strategy: the rejection of negotiations, the abandonment of protracted warfare, and the focus on the offensive in the towns and cities of South Vietnam. More arrests followed in November and December. The operational plan for the general offensive and uprising had its origin as the "COSVN proposal" at Thanh's southern headquarters in April 1967 and had then been relayed to Hanoi
12125-401: The possible perceptions of the American public to such an increased estimate since communist troop strength was routinely provided to reporters during press briefings. According to MACV's chief of intelligence, General Joseph A. McChristian , the new figures "would create a political bombshell", since they were positive proof that the North Vietnamese "had the capability and the will to continue
12250-550: The question whether the U.S. strategy of attrition was working in South Vietnam weighed heavily on the minds of the American public and the administration of President Lyndon B. Johnson . General William C. Westmoreland , the commander of the Military Assistance Command, Vietnam (MACV), believed that if a "crossover point" could be reached by which the number of communist troops killed or captured during military operations exceeded those recruited or replaced,
12375-526: The road to the capital. On 12 April, the PAVN struck again, this time moving in from eastern Laos and seizing a series of border outposts around Đắk Tô in Kon Tum Province in the Central Highlands . The PAVN then proceeded east toward the provincial capital of Kon Tum . Hanoi had initiated the offensive to coincide with the winter monsoon, when continuous rain and low cloud cover made air support difficult. The initial U.S. response to
12500-512: The same period. The North was feeling the pressure, admitting in the official PAVN history that "between May and June only 30 percent of supplies called for in our plan actually reached the front-line units." In total, 41,653 Linebacker missions dropped 155,548 tons of bombs. In addition to interdicting the road and rail system of North Vietnam, Linebacker also systematically attacked its air defense system. The VPAF, with approximately 200 interceptors, strongly contested these attacks throughout
12625-474: The six autonomous cities, 72 of 245 district towns and the southern capital. The offensive was the largest military operation conducted by either side up to that point in the war. Hanoi had launched the offensive in the belief that it would trigger a popular uprising leading to the collapse of the South Vietnamese government. Although the initial attacks stunned the allies, causing them to lose control of several cities temporarily, they quickly regrouped, repelled
12750-410: The task easier due to the fact that he was faced with a fait accompli . Since the Politburo had already approved the offensive, all he had to do was make it work. He combined guerrilla operations into what was basically a conventional military offensive and shifted the burden of sparking the popular uprising to the VC. If it worked, all would be well and good. If it failed, it would be a failure only for
12875-475: The time of the invasion fewer than 10,000 U.S. combat troops remained in South Vietnam, and most of them were scheduled to leave within the next six months. The number of combat aircraft stationed in Southeast Asia was less than half that of its peak strength in 1968–1969. At the beginning of 1972, the U.S. Air Force (USAF) had only three squadrons of McDonnell Douglas F-4 Phantom II fighter-bombers and one squadron of Cessna A-37 Dragonfly light attack aircraft,
13000-592: The two periods of sustained air operations against North Vietnam (March 2, 1965, to October 31, 1968, and March 30, 1972, to December 29, 1972) there were normally three carriers on the line, each conducting air operations for twelve hours, then off for twelve hours. One of the carriers would operate in Vietnam territorial waters from noon to midnight, another from midnight to noon, and one during daylight hours, which gave 24-hour coverage plus additional effort during daylight hours, when sorties were most effective. However at
13125-399: The war to admit that the current war strategy required reevaluation. The offensive had a strong effect on the U.S. government and shocked the American public, which had been led to believe by its political and military leaders that the North Vietnamese were being defeated and incapable of launching such an ambitious military operation. American public support for the war declined as a result of
13250-521: The will of their domestic opponents and reaffirm their autonomy vis-à-vis their foreign allies", hundreds of pro-Soviet, party moderates, military officers, and intelligentsia were arrested on 27 July 1967, during what came to be called the Revisionist Anti-Party Affair . All of the arrests were based on the individual's stance on the Politburo's choice of tactics and strategy for the proposed general offensive. This move cemented
13375-689: Was a major escalation and one of the largest military campaigns of the Vietnam War . The Viet Cong (VC) and North Vietnamese People's Army of Vietnam (PAVN) launched a surprise attack on 30 January 1968 against the forces of the South Vietnamese Army of the Republic of Vietnam (ARVN), the United States Armed Forces and their allies . It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. The name
13500-429: Was a military defeat for North Vietnam, as neither uprisings nor ARVN unit defections occurred in South Vietnam. However, this offensive had far-reaching consequences for its effect on the views of the Vietnam War by the American public and the world broadly. General Westmoreland reported that defeating the PAVN/VC would require 200,000 more American soldiers and activation of the reserves, prompting even loyal supporters of
13625-1103: Was a single carrier point for conducting strikes within South Vietnam from May 15, 1965, to August 3, 1966. Tet Offensive In Phase One: [REDACTED] South Vietnam: 4,954 killed 15,917 wounded 926 missing [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] Others: 4,124 killed 19,295 wounded 604 missing Total casualties in Phase One : 45,820 casualties: In Phase One: RVN/U.S. claimed: One PAVN source (Saigon only): Phase One, Phase Two and Phase Three : Trần Văn Trà reports (Phase One and Two): 75,000+ killed and wounded PAVN source (total for 3 phases): 111,179 casualties: American intervention 1965 1966 1967 Tet Offensive and aftermath Vietnamization 1969–1971 1972 Post- Paris Peace Accords (1973–1974) Spring 1975 Air operations Naval operations Lists of allied operations The Tet Offensive
13750-537: Was aimed at influencing the South Vietnamese public, not that of the U.S. There is conflicting evidence as to whether, or to what extent, the offensive was intended to influence either the March primaries or the November presidential election in the U.S. According to General Trần Văn Trà , the new military head of COSVN, the offensive was to have three distinct phases: Phase I, scheduled to begin on 30 January, would be
13875-403: Was an immediate impact on the battlefield in South Vietnam. Shelling by PAVN artillery dropped off by one-half between 9 May and 1 June. This slowdown was not due to an immediate shortage of artillery shells, but rather to a desire to conserve ammunition. U.S. intelligence analysts believed that PAVN had enough stockpiled supplies to sustain their campaigns throughout the autumn. The intensity of
14000-455: Was billed as a "high-level policy review". Upon their arrival, the two men bolstered the administration's claims of success. From Saigon, pacification chief Robert Komer asserted that the CORDS pacification program in the countryside was succeeding, and that sixty-eight percent of the South Vietnamese population was under the control of Saigon while only seventeen percent was under the control of
14125-609: Was convinced that the PAVN planned to stage an attack and overrun the base as a prelude to an all-out effort to seize the two northernmost provinces of South Vietnam. To deter any such possibility, he deployed 250,000 men, including half of MACV's U.S. maneuver battalions, to I Corps. Operation Linebacker American intervention 1965 1966 1967 Tet Offensive and aftermath Vietnamization 1969–1971 1972 Post- Paris Peace Accords (1973–1974) Spring 1975 Air operations Naval operations Lists of allied operations Operation Linebacker
14250-460: Was credited with his fifth MiG, making him the final Air Force ace. Although Linebacker was largely carried out by air, naval forces were also deployed to provide counter-battery fire against enemy targets along the coast and other important logistical areas and in support of ground troops. One such operation was Operation Lion's Den, or "The Battle of Haiphong Harbor". On 27 August 1972, Vice Admiral James L. Holloway III took with him his ship,
14375-401: Was decisive in his actions and gave the military greater latitude in targeting; American airpower was forcefully and appropriately used; and the immense difference in the technology utilized made Linebacker the first bombing campaign in a "new era" of aerial warfare. During and immediately following the PAVN offensive, U.S. Air Force, Navy and Marine Corps aviators had flown 18,000 sorties in
14500-488: Was fed to the press and to the Congress . "We are beginning to win this struggle", asserted Vice President Hubert H. Humphrey on NBC 's Today show in mid-November. "We are on the offensive. The territory is being gained. We are making steady progress." At the end of November, the campaign reached its climax when Johnson summoned Westmoreland and the new U.S. Ambassador, Ellsworth Bunker , to Washington, D.C., for what
14625-520: Was flown by aces Duke Cunningham and William P. Driscoll ). By the end of the month, American aircraft had destroyed 13 bridges along the rail lines running from Hanoi to the Chinese border. Another four were destroyed between the capital and Haiphong, including the notorious Thanh Hóa Bridge. Several more bridges were brought down along the rail line leading to the south toward the DMZ. Targets were then switched to petroleum and oil storage and transportation networks and North Vietnamese airfields. There
14750-435: Was fueled not by a belief that the struggle was not worthwhile, but by mounting casualty figures, rising taxes, and the feeling that there was no end to the war in sight. A poll taken in November indicated that 55 percent wanted a tougher war policy, exemplified by the public belief that "it was an error for us to have gotten involved in Vietnam in the first place. But now that we're there, let's win – or get out." This prompted
14875-401: Was not going to come easily. American bombers would once again return to the skies of North Vietnam in 1972 during Operation Linebacker II before the American commitment to the Vietnam War came to an end. (Air-to-air losses only, claimed by the U.S) According to the VPAF, they lost 47 MiGs in aircombat (including 26 MiG-21s, 5 MiG-19s and 16 MiG-17s) Between 10 May and 23 October 1972,
15000-460: Was prepared to up the ante, stating that "the bastards have never been bombed like they're going to be bombed this time". On 27 April, ARVN defenses in Quảng Trị Province began to collapse. Due to conflicting orders from their high command, ARVN units joined an exodus of refugees heading southwards, abandoning Quảng Trị city. PAVN forces entered the city on the same day as the meeting between Kissinger and Le Duc Tho. The PAVN offensive had become
15125-463: Was set up in 2nd Air Division headquarters. A U.S. Air Force liaison officer was posted to USS Kitty Hawk to coordinate the naval aviators with Air Force operations; in turn, a party of five naval personnel were detailed to the command post. Committed to a mission in which half the planes drew ground fire, and lacking a formal combat search and rescue backup, the mission suffered its first loss on 6 June 1964 when Lieutenant Charles F. Klusman
15250-483: Was shot down while flying at 1,200 feet. Air America attempted rescue without success. Flak suppression protocols had not yet been figured out; use of napalm , the most successful counter to anti-aircraft batteries, was banned by the American ambassador to Laos, Leonard Unger . A second plane went down during the would-be CSAR. After settling into secretive run air strikes against communist infiltrators into Laos, Yankee Team morphed into Operation Barrel Roll . During
15375-708: Was the codename of a U.S. Seventh Air Force and U.S. Navy Task Force 77 air interdiction campaign conducted against North Vietnam from 9 May to 23 October 1972, during the Vietnam War . Its purpose was to halt or slow the transportation of supplies and materials for the Nguyen Hue Offensive (known in the West as the Easter Offensive ), an invasion of the South Vietnam by the North Vietnamese People's Army of Vietnam (PAVN) that had been launched on 30 March. Linebacker
15500-509: Was the first continuous bombing effort conducted against North Vietnam since the end of Operation Rolling Thunder in November 1968. At midday on 30 March 1972, 30,000 PAVN troops, supported by regiments of tanks and artillery, rolled southward across the Demilitarized Zone (DMZ) that separated the two Vietnams. This three-division force caught the Army of the Republic of Vietnam (ARVN) and their American allies unprepared. The PAVN force struck
15625-562: Was usually presented as the result of a perceived U.S. failure to win the war quickly, the failure of the American bombing campaign against North Vietnam, and the anti-war sentiment that pervaded the population of the U.S. The decision to launch the general offensive, however, was much more complicated. The decision signaled the end of a bitter, decade-long debate within the North Vietnamese Government between first two, and then three factions. The moderates believed that
