Description
This period was from April 1 -October 31, 1968.
On April 1, 1968 the United States suspended bombing in North Vietnam north of the 20th parallel to encourage North Vietnam to agree to peace negotiations which it did 2 days later. At that time, President Lyndon B. Johnson moved the bombing ban farther south to the 19th parallel. U.S. and North Vietnamese diplomats met in Vientiane, Laos on April 25 to choose a site for the peace talks and on May 3 they agreed to meet in Paris, France. Preliminary discussions between representatives of the United States and the Democratic Republic of Vietnam began in Paris on May 10. A month later on June 11. Gen. Creighton Abrams, USA became Commander of MACV. Then on August 1, Gen. George S. Brown replaced General Momyer as Commander. Seventh Air Force.
On July 14, 1968, the U.S. began another interdiction campaign between the 19th parallel and the DMZ. American pilots struck rail cars. watercraft. trucks. and storage areas. They also bombed roads leading to Mu Gia and Ban Karai Passes on the Laotian border to disrupt movement of North Vietnamese supplies and personnel into Laos destined for South Vietnam. Following the cessation of bombing north of the 19th parallel. North Vietnam began to rebuild its industry, transportation network, stores of war materiel, and air defenses. It also moved its MiGs most of which had been based in China. back into the country. Still. North Vietnamese pilots generally
avoided the panhandle south of the 19th parallel. Attempting to encourage progress in the Paris peace negotiations. President Johnson on October 31, 1968, ordered a halt to all bombing in North Vietnam. The conflict in Laos became more active in 1968 as the Communists increased their efforts during April to send supplies, equipment, and personnel down the Ho Chi Minh Trail before the impending monsoon wet season (mid-May to early October) made the roads impassable.
To counter this infiltration. between April 19 and June 10. B-52 crews. flying up to 30 sorties each day bombed truck parks and storage areas along the trail. The Seventh Air Force meantime used its tactical assets to hit small targets, such as trucks and other surface traffic on the move and to make follow-up raids on the B-52 targets along the Ho Chi Minh Trail. In northern Laos the USAF continued to provide close air support to Dorian troops battling the Pathet Lao and North Vietnamese forces. In May 1968 the enemy massed forces at Na Khang 150 miles northeast of Vientiane and 100 miles east of Luang Prabang. The USAF increased its close air support in the face of this threat and by the end of October, the Laotians had driven the Communist forces back to Samneua about 35 miles northeast of Na Khang.
In South Vietnam, during the summer of 1968. the USAF flew closeair support. interdiction and airlift missions in support of Allied forces, while the Communists launched another offensive. A typical Communist attack occurred on August 23 against Duc Lap, a border camp 3 miles east of Cambodia and 35 miles southwest of Ban Me Thuot. a town 160 miles northeast of Saigon. The next day the 483rd Tactical Airlift Wing‘s C-7s joined U.S. Army helicopters in resupplying and reinforcing Duc Lap. Heavy tactical air strikes drove the enemy from the camp's perimeter and suppressed enemy fire permitting aerial resupply. To help check similar attacks, USAF tactical aircraft and B-52s provided close air support while airlifters flew in or airdropped supplies to several other Army Special Forces camps. The Viet Cong and North Vietnamese were not nearly as well equipped as they had been during the Tet Offensive and by mid-September the Allies had blunted this offensive.
