s 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 The B-52s were then withdrawn from operations in the north and when they returned in June, their missions would be limited to South Vietnam.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 the first time in over three years. Air Force and Navy commanders and pilots were relieved that Nixon (unlike President Johnson) left the operational planning to local commanders and loosened the targeting restrictions that had hampered Operation Rolling Thunder. Between 1 May and 30 June B-52s, fighter-bombers, and gunships had flown 18,000 sorties against formidable anti-aircraft defenses with the loss of 29 aircraft.

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.

As a result of this meeting and the fall of Quảng Trị City Nixon was prepared to up the ante, stating that "the bastards have never been bombed like they're going to be bombed this time".

city. PAVN forces entered the city on the same day as the meeting between Kissinger and Le Duc Tho. The PAVN offensive had become 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 the President, who approved it on 8 May.Tilford, p. 233.
Shortly after his inauguration, Nixon had ordered the preparation of a contingency plan, one that would hopefully bring the Vietnam War to an end.Morocco, p. 130.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 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''.

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 the killing is to take the weapons of war out of the hands of the international outlaws of North Vietnam.".Morocco, p. 131. 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.

Going north
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 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 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 the first day of the operation, 120 by the Air Force and 294 by the Navy and they encountered the heaviest single day of air-to-air combat during the Vietnam War, with 11 VPAF MiGs (four

).
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 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 the bombing campaign was reflected by the sharp increase in the number of strike and support sorties flown in Southeast Asia as a whole: from 4,237 for all services, including the RVNAF, during the month preceding the invasion, to 27,745 flown in support of ARVN forces from the beginning of April to the end of June (20,506 of them flown by the Air Force).Head, p. 66. B-52s provided an additional 1,000 sorties during 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 the campaign. Navy pilots, employing a mutually supporting "loose deuce" tactical formation and many with

training, enjoyed a kill ratio of 6:1 in their favor in May and June, such that after that the VPAF rarely engaged them thereafter. In contrast, the USAF experienced a 1:1 kill ratio through the first two months of the campaign, as seven of its eventual 24 ''Linebacker'' air-to-air losses occurred without any corresponding VPAF loss in 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 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 4:1 kill ratio.
''Linebacker'' saw several other "firsts". On the opening day of the operation, USN Lieutenant Duke Cunningham and his radar intercept officer, Lieutenant (j.g.) William P.

Paris Peace Talks and conclusion
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 the ouster of South Vietnamese President

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 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 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 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 the beginning of ''Freedom Train'' in April to the end of June 1972 the United States lost 52 aircraft over North Vietnam: 17 to missiles; 11 to anti-aircraft weapons; three to small arms fire; 14 to MiGs; and seven to unknown causes. 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 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 the campaign had been successful in its interdiction effort. USAF General Robert N. Ginsburgh, of the

, summed up the attitudes of U.S. commanders by remarking that ''Linebacker'' had "a greater impact in its first four months of operation than ''Rolling Thunder'' had in three and one-half years." Although Kissinger may have announced that peace was at hand, it was not going to come easily. American bombers would once again return to the skies of North Vietnam in 1972 during
