search-and-destory operation The major battle of the operation occurred on 11 April when Company C, 2d Battalion, 16th Infantry fought the VC force. The U.S. killed a few of the VC and then followed the retreating soldiers. However, the VC were falling back on their battalion base. The VC attacked with mortar, automatic weapons and human-wave assaults. Company C had to be evacuated by helicopter. Company B reached the battle area before dawn, but there were no other major contacts. During this operation, Allied forces penetrated VC jungle, but the area was still controlled by the Communists. Gen. Johnson, the Army Chief of Staff, realized that more high casualty battles like Operation ABILENE would result in a loss of the American public's support.

to push VC away from a major rice producing area near Sai Gon; search-and-destroy In December of 1966, the US troops occasionally made contact with the VC near Duc Hoa. In 1967 the Division moved to along Highway 1. CEDAR FALLS was taking place at the same time and part of the division temporarily served there. In Late February the divison saw the heaviest action. The 4th Battalion, 9th Infantry and the 3d Squadron, 4th Cavalry engaged in a fight northeast of Cu Chi. After CEDAR FALLS ended, the action shifted to around Duc Hoa. During the time that the 25th Division was carrying out ALA MOANA, elements of the division pariticpated in JUNCTION CITY. Most of the division was assigned to clearing operations during ALA MOANA. However, little contact was made. After the operation concluded, the 25th Division focused on pacification in Hau Nghia Province.

to keep pressure on PAVN units and base camps in the A Shua Valley; to disrupt and destroy PAVN units to prevent attacks on the coastal provinces (included battle of Ap Bia Mountain or "Hamburger Hill"); a sweep and clear operation During the operation, most units encountered some resistance from the PAVN. However, the 3d/187th engaged in the most heavy fighting as they approached Ap Bia Mountain (Hill 937). Here the PAVN uncharacteristically decided to stand against U.S. frontal attacks. The 3d/187th assaulted the hill for three days before they were reinforced. Then two other 101st Airborne Division battalions and a battalion from the 3d ARVN Regiment joined the original battalion to fight against the 7th and 8th Battalions of the 29th PAVN Regiment in the major battle of APACHE SNOW. It became one of the bloodiest battles in the war. A two battalion assault nearly took the hill on 18 May when weather forced them back. Finally on the 20 May, the PAVN were forced out of A Shau and into Laos. However, they soon returned after the Allied forces withdrew. This caused more controversy in the U.S. concerning the lives spent to take the territory when it was only abandoned for the Communists to reoccupy. Eventually this led to limitations on U.S. military operations. Vietnam: Order Of Battle, by Selby L.

31 B-52s lost



USAF B-52 bombing missions to support ground tactical operations and to interdict enemy supply lines in Vietnam, Laos, and Cambodia and later to strike at targets in North Vietnam These operations were most often used in close air support (CAS) bombing raids of enemy base camps, troop concentrations, or supply lines. They were usually carried out at high altitudes and often called "aerial excavations" by the ground forces. Most of the sorties were carried out in South Vietnam, though a few were flown near the DMZ. The first ARC LIGHT raid occured on 28 June 1965, and though the media questioned its effectiveness, Gen. Westmoreland continued to support the program. Most missions during 1965 were saturation attacks, with a few tactical support missions. Eventually the need to deliver bigger payloads led to increasing the amount of bombs the B-52D could carry in the "Big Belly" program. In April of 1966, the bombers raided outside South Vietnam for the first time when bombing Laos to stop PAVN inflitrations in the Mu Gia Pass and later the Ho Chi Minh Trail. In 1968, the B-52s supported the U.S. Marines at Khe Sanh and attacked other targets including the A Shau Valley, the Kontum-Dak To border area, and the PAVN/VC infiltration area in War Zone C. Strikes continued throughout 1969. Vietnamizationn began to reduce ARC LIGHT raids during 1970, though missions continued to be flown in Laos and Cambodia. In April 1970, the B-52s flew in COMMANDO HUNT III. In response to the PAVN's Easter Offensive, the bombers participated in raids on Ha Noi and Hai Phong. LINEBACKER I and LINEBACKER II were composed of ARC LIGHT missions. Even though Ha Noi agreed to return to negotiations on 30 December 1972, the bombings continued until 15 August 1973 due to cease-fire violations. At the end of ARC LIGHT, 55 percent of the sorties were flown in South Vietnam. The USAF lost 31 B-52s, 18 to enemy fire and due 13 to operations problems.

part of the larger TOAN THANG III Operation beginning on 17 February 1969; to enact the Vietnamization program with securing the local hamlets from VC and PAVN inrfiltration and control, while supporting the ARVN units that were to manage the area. The operation targeted the 7th PAVN Division. Major contact developed on 30 March as the 1st Squadron, 4th Cavalry followed a platoon-sized PAVN force north until the U.S. men came under fire in an ambush. The cavalry-men positioned their armored personnel carriers (APCs) so that all the automatic weapons could be fired at the attackers. The Charlie Troop began to move south. Then Bravo Troop moved in to continue the attack. The PAVN suffered heavily. This operation was followed on 10 April by ATLAS POWER.

A search-and-destroy operation meant to combat test the 196th Light Infantry Brigade against "light" guerrilla opposition This operation began as a single battalion air assault leading to a search-and-destroy mission. By the time it ended in November, it had expanded into the largest U.S. Joint operation of the war at that time. During Phase I, there was relatively little contact with the VC as the 196th Infantry Brigade conducted operations in the area. In late October / early November(?) the 196th Brigade and the 1st Battalion, 27th Infantry encountered the 9th VC Division. During Phase II, the 27th Infantry and the 9th VC Division's Regiments fought a major three day battle. More contacts with the VC expanded the operation and command eventually passed from the 1st Infantry Division to II Field Force, the U.S. headquaters near Saigon. During Phase III, the 1st Infantry Division took over the fight. Soon afterwards, the 3d Brigade, 1st Division moved into Suoi Da and the 1st Battalion, 28th Infantry moved to a landing zone to the north. The 2d Battalion, 28th Infantry had cleared the area and both battalions were in position by nightfall. On 8 November, reconnaissance-by-fire began under the 1st Battalion's command. The VC began to use intense fire and the VC began to assault the perimeter. 1st Battalion artillery fire and air strikes defeated the VC. The operation included many other battles between the Allied forces and the Communists, but the battle on the 8th was probably the most significant. At its conclusion, a large base camp was discovered which housed one of the largest weapons caches found up to that time. Operation ATTLEBORO illustrated that, due to better maneuverability and firepower, the Allies had an advantage in stand-up fights. This would be tested again in later operations.

Barrel Roll Laos northern Laos; stretching from Vientiane at the Thailand border north to the strategic Plain of Jars and then northeast to the Pathet Lao capital fo Sam Neua bordering Nnorth Vietnam 6/9/1964 4/17/1973 USAF: Hmong and irregular units; Royal Lao Air Force (RLAF); Royal Lao Army (RLA) PAVN; Pathet Lao






to support ground forces of the Royal Laotian Government (RLG) and the CIA-trained Hmong irregular forces of Gen. Vang Pao This operation originated in response to the failure of the 1962 Geneva Accords which would have set Laos as an independent and neutral state. In response to the Pathet Lao/PAVN offensive in the Plain of Jars, Johnson approved this air operation beginning in 1964. The attacks began on 9 June 1964. Throughout the operation, the U.S. ambassador in Vientiane controlled the air operations, mainly by validating targets. The operation attempted to support the RLG forces and the Royal Lao Air Force (RLAF). Headquarters 2d Air Division/ Thirteenth Air Force at Udorn, Thailand actually ran BARREL ROLL. Later this unit was designated Seventh Air Force / Thirteenth Air Force. Operations centers were set up in each military region. The American forward air controllers (FACs) not only supported the Royal Lao air and ground units, but also the Hmong units. All of this was risky because Laos and the United States were pretending to follow the Geneva Accords and not place belligerent forces in Laos. Because of Laos' weather, the campaign took on a regular pattern. The PAVN operated as the regular forces while the Loatian were often guerilla units and sometimes poor fighters. The Hmong, who fought for the Allies, used the monsoon season to take the offensive while the PAVN/Pathet Lao forces used the dry season for counterattacks. Though the RLG forces were usually outnumbered and outgunned, they had significant U.S. and RLAF air power support. With this support, they were able to hold their own and even launch successful offensives. In August 1966, the Hmong pushed in close to North Vietnam, but a 1967 counterattack by the Pathet Lao and PAVN overran several key Royal Lao and Hmong positions. The U.S. used its air power to give the Hmong and the RLG the advantage again during the 1967 monsoon season. Then in the 1967-1968 dry season, the PAVN attacked with Soviet supplies. They captured LS85 which had a tactical navigation system defended by the U.S. Seven U.S. airmen were killed. Even though during the 1968-1969 season the Communists were better equipped, the RLG forces enjoyed some of their greatest victories. Aircraft was diverted from ROLLING THUNDER to support the RLG. By September, the RLG forces had taken land all the way to the Plain of Jars as well as supplies and ammunition. The Communist counteroffensive at the end of 1969 and the beginning of 1970 resulted in all the RLG gains being lost. B-52 strike were called to save the situation. 1971 resulted in another Communist success, followed by more victories by the determined Hmong forces. Cease-fire negotiations began on 10 November 1972. The Communists used this time to take more Hmong outposts. On 21 February 1973 the U.S. signed a cease-fire. Though they continued to fly B-52 sorties, these were futile gestures due to cease-fire violations. The last sortie was flown on 17 April 1973. Though the number of sorties and performance of the forces were impressive, all this was futile in the end.

This was the third MACV Cambodian assault The U.S. 4th Infantry Division did not particpate in this operation for long because it had recently been relocated to the area and had no forward installations and limited logistical support. When the 3d Battalion, 506th Infantry attempted to land , they encountered heavy fire and the insertions were aborted. The next day, the 3/506th and 1st Battalion, 14th Infantry were under heavy fire on the ground. The 2d Battalion, 8th Infantry joined them on the 6th of May. Since the battalions were taking heavy casualties, the U.S. commander decided to turn the operation over to the ARVN. The U.S. withdrew and continued to support the ARVN 22d and 23d Divisions, 2d Ranger Group, and 2d Armored Brigade by air and artillery from inside south Vietnam. Later, captured documents revealed that the PAVN forces had been ordered to avoid direct contact. The Encyclopedia Of The Vietnam War: A Political, Social & Military History, edited by Spencer C.

to support the pacification of the peninsula by clearing out VC forces and converting the Communist stronghold into an area of government control In this operation, the U.S. forces helped to round up VC forces. They relocated civilians to tents where they were screened for VC cadres, and then returned home. CORDS and the government approved these actions because the civilians would be returned to their homes in about a month. When the operation began, the USMC battalions landed on the peninsula while Task Force Cooksey from the 23d Division blocked the southern boundary. During the time of the operation, Army engineers destroyed more than 13,000 yards of underground passages and hiding places along with all the houses in the area of operation. The 23d Division claimed it identified 256 memebers of the Viet Cong Infastructure, though some reports place the number as low as 50. The civilians were not allowed to rebuild on their original home sites, but were moved to new settlements south of the peninsula. It was not untl 1971 when security improved enough to allow the refugees to return home. This operation mainly succeeded in alienating the people. There were no lasting military gains. The area remained insecure and the VC continued to assert a major influence on the people. This operation was later followed by NANTUCKET BEACH.

ruse designed to engage North Vietnamese MiG-21s Before April 1967, Washington would not allow the Air Force to bomb DRV airfields and destroy the enemy's aircraft while it was grounded. Operation BOLO became a plan to lure the MiG-21s into the air where they could be defeated. F-4s imitated the formations of slower F-105s to convince the DRV that the USAF planes were on a normal strike mission. The MiG-21s that were sent up found the quicker F-4s ready to fight. Originally the mission included 14 flights of USAF fighters: 28 Phantoms from the 8th TFW and 28 from the 366th TFW. Due to weather, the 366th was not able to reach the area. Only three flights actually fought. The dogfight lasted 15 minutes, and the DRV lost seven MiG-21s. The USAF aircraft returned to base safely. This was the largest single aerial dogfight of the Vietnam War. The Encyclopedia Of The Vietnam War: A Political, Social & Military History, edited by Spencer C.

To defend the Con Thien combat base; search and destroy operation This operation followed Operation CIMARRON and was succeded by Operation HICKORY II. Con Thien, because of its position, was widely considered to be the most important natural observation post along the DMZ. Prior to BUFFALO, PAVN troops were positioning across the DMZ to invade Quang Tri Province. On 2 July Companies A and B of the 1/9 came under fire from PAVN battalions in positions designated for regrouping and employment of heavy artillery. Company C was deployed to Company B's area and tanks from Company D were sent. Company D secured the LZ aand evacuated casualties. Later, the 3/9 was sent in to assist the 1/9. There was constant heavy artillery fire and mortar. On 3 July BLT 1/3 joined the battle, as did BLT 2/3 on the next day. The plan was to drive north in an attempt to push th PAVN out of the Lang Son area. Both battalions were under heavy artillery fire. Throughout the night of the 6th, PAVn continued to pressure the Marines. On the 7th Company A pulled back to the battalion perimeter. That afternoon the Marines began to counter the attack with supporting arms, attack aircraft, flare ships, naval gunfire, and artillery. By the 8th the Marines had repelled the Communits and PAVN had withdrawn across the Ben Hai River. The last major conflicts of the operation also occurred on the 8th when Companies F and G fell under fire. The operation had held Con Thien and reaffirmed Marine docterine of coordinating ground and air commands, but PAVN had also increased their use of accurate long range artillery and SAMs. Vietnam: Order Of Battle, by Shelby L.

relieve pressure on the National Khmer Armed Forces, destroy Communist sanctuaries, capture the headquarters of the Central Office for South Vietnam, demonstrate Vietnamization, buy time for U.S. troops withdrawal, & break the bargaining stalemate Excursions into Cambodia began in April when RVN forces initiated raids against Communist bases in Parrot's Beak. There were 13 major combat operations in Cambodia during the following months, two of which included U.S. ground units. The other operations were accompanied by U.S. advisors and supported by U.S. air assets. In all, this was the largest series of Allied operations since JUNCTION CITY. There were three groups of operations: TOAN THANG (Total Victory) with ARVN III Corps and U.S. II Field Force; CUU LONG (Mekong) with ARVN IV Coprs; and BINH TAY (Tame the West) with ARVN II Corps and U.S. I Field Force. The ARVN units would reach deeper than 60 kilometers into Cambodia, while the U.S. forces would not push farther than 30 kilometers inside the borders. TOAN THANG 42 was an entirely ARVN operation meant to clear Communist base areas in the Parrot's Beak. During some phases of the operation, the ARVN and National Khmer Armed Forces (FANK) worked together. Eventually they had thwarted the Communist plans to overthrow the Lon Nol regime and captured or killed 3,588. During TOAN THANG 43-46, joint U.S.-ARVN operations worked to clear communist sanctuaries in the Fishhook area. The mission largely became one of search-and-destory when it became obvious that the PAVN would avoid open-battlefield confrontations. The 1st Cavalry stumbled across many supplies during this time, and this part of the Cambodian incursion accounted for 3,190 Communist troops killed or captured. Increased Communist activity forced TOAN THANG 46 to end by 20 June. The ARVN operation CUU LONG I began on 9 May to open the Mekong River. ARVN divisions cleared the banks of the river and repatriated nearly 20,000 Vietnamese in refugee camps. In CUU LONG II, ARVN IV Corps and FANK forces worked together to recapture Takeo and clear Routes 2 and 3. Finally in CUU LONG III, ARVN IV Corps again joined FANK forces to reestablish control over towns and evacuate more ethnic Vietnamese. About this same time, the Allies began to attack bases in Cambodia facing II Corps. These operations were designated BINH TAY I-IV and included ARVN 22d and 23d Infantry divisions, the 2d Ranger Group, the 2d Armor Brigade, and two U.S. 4th Infantry Division brigades. However U.S. participation was brief. The 4th Division ws overextended, and upon attempting to insert into Cambodia, they suffered significant casualties and several downed helicopters. By 16 May, all 4th Division troops had left Cambodia and turned the operation over to the ARVN. In BINH TAY II, ARVN units uncovered more supplies and weapons and in BINH TAY III they searched for Enemy Base Area 740. In BINH TAY IV, ARVN troops pushed back to a FANK garrisonn at Labang Siek and evacuated its 7,000 Khmer soldiers and dependents across the border into Pleiku Province. By 27 June, all II Corps ARVN troops had left. U.S. ground troops left Cambodia by 30 June, but ARVN units continued to operate up to 60 kilometers inside Cambodia all the way into 1971. Throughout the invasion, there were 2,328 Communist soldiers who rallied or were captured. Though the Cambodian incursion captured ten times the supplies captured in Vietnam the previous year, temporarily reduced pressure on Lon Nol, lessened dangers to withdrawing U.S. troops, and displayed ARVN improvement, it was not as succesful as believed. It became obvious that the ARVN depended on U.S. air support and had numerous problems on the tactical and organizational level. This appeared again during the operations in Laos in 1971. The Communists quickly returned to eastern Cambodia and seized more towns in southern Laos while expanding the Ho Chi Minh Trail. As the U.S. continued to withdraw, the ARVN had to deploy troops in III Corps and reduce their strength in the north. The Communist threat grew. Meanwhile in the U.S., the anitwar movement gained a new rallying point. In the end, the Cambodian Invasion turned the war into one for all of Indo-China, which ARVN and FANK troops could not defend on their own. Vietnam: Order Of Battle, by Shelby L.

To interdict VC control of the transportation and communications network in the area; search and destroy operation to seal off the Iron Triangle and crush everything within it The II Field Force (IIFFV) chose a "hammer-and-anvil" attack to be used on the target, with the anvil along the Saigon River at the southwestern boundary of the Iron Triangle and the hammer to swing through the triangle. The local residents were evacuated and the area was cleared of vegetation. The plan was only known to a few IIFFV personel and ARVN was not brieffed until two days beforehand. During Phase I, from 5-8 January, the anvil was positioned with the ARVN VNN forces, the 25th Infantry Division, and the 199th Light Infantry Brigade setting up south of the Saigon River. On 9 January, Phase II began with the hammer movement of the 11th Armored Cavalry and the 173d Airborne Brigade and the airmobile assaults of the 3d Brigade, 1st Infantry Division. With two U.S. and one ARVN infantry divisions, this was the largest operation to date. The 1st Battalion, 26th Infantry attacked Ben Suc, the VC headquarters in the secret base area, and three surrounding villages. The battalion was airlifted into the Ben Suc and by midmorning had secured the village. Meanwhile the forces involved in the hammer conducted search-and-destroy methods, searching by day and amsbushing by night. The VC avoided defensive positions as they tried to slip away from the Iron Triangle area. As the operation ended, the 1st Squadron, 4th Cavalry protected the engineer forces still clearing the area until 26 January. CEDAR FALLS provided lessons concerning the infantry and engineers working together to uncover the VC as well as refined the systems for clearing VC tunnel systems and preparing helicopter landings. VC documents revealed much to the Allies about their enemies and the VC were siginificantly setback in the area, though far from destroyed. There were 280 VC POWs.
