Delaware / Lam Son 216
Operation
Dates: 4/18/1968 - 5/17/1968
Combat Tactical Zone: I
Tactical Area of Operation: Quang Tri and Thua Thien Provinces - A Shau Valley

The original plan called for the 1st Cavalry Division and ARVN 3d Regiment to assault into the valley while the 1st Brigade, 101st Airborne and ARVN Ariborne Division blocked the routes of escape. The 1st Squadron, 9th Cavalry conducted air reconnaissance throughout the area and found anti-aircraft supplies. Even after these areas were attacked, the PAVN still brought down 23 helicopters. Fighting began on 19 April when the 5/7th and 1/7th landed on the peaks on the northern end of the valley. The PAVN tested the U.S. defenses that night. Weather became so bad that the 1/7th had to seek lower elevation to be resupplied. The 1st Brigade, 1st Cavalry Division began assautling the A Luoi airstrip, and the battle soon turned into an airhead. The 1st Brigade turned to the south and west, where they discovered a PAVN storage area. This area, nicknamed the "Punchbowl", was secured by May 3. Earlier, the ARVN 3d Regiment pushed south along the Rao Lao River where they found a large supply cache. To the east, the 101st Airborne and ARVN Airborne troops also found large caches. Meanwhile, the PAVN fired artillery and rockets from Laos. DELAWARE-LAM SON 216 was a success in capturing supplies, however PAVN troops returned after only a few weeks.

Operation
Combat Tactical Zone: I
Tactical Area of Operation: Gulf Of Tonkin; Coast of the DRV

This operation was originally supposed to last four months, but was extended for an additional year. The first mission was canceled because of weather, and then the Maddox was sent to the Tonkin Gulf. On 31 July 1964, two OPLAN 34A teams attacked the islands of Hon Me and Hon Ngu. Though the Maddox monitored this activity from a five mile distance, the ship was still attacked on 2 August by North Vietnamese patrol boats. The Vietnamese were driven back by aircraft from the carrier Ticonderoga. The Constellation and C. Turner Joy were called in as reenforcements. On 4 August, a second attack on the Maddox and the C. Turner Joy caused Johnson to suspend both DeSoto and OPLAN 34A. Congress passed the Gulf Of Tonkin Resolution and American involvement in the war grew.

Operation
Dates: 1/22/1969 - 3/18/1969
Combat Tactical Zone: I
Tactical Area of Operation: Quang Tri Province and Thua Thien Provinces - A Shau Valley toward Da Krong Valley

At the opening of the operation the 9th Regiment was sent into the Da Krong Valley, where they were completely dependent on helicopters for logistical support. This was often difficult because it was monsoon season. They developed fire support bases (FSBs) Shiloh, Razor, and Riley. As they pushed forward, the regiment opened more FSBs. Phase I of DEWEY CANYON focused on getting the forces established in the area. During Phase II, the troops cleared the area around the FSBs and prepared for Phase III. The 2/9th and 3/9th were ordered to extend their perimeters north of the Da Krong River, however because of the weather and limited supplies, they were later ordered to pull back in. This, along with the continued bad weather, allowed the Communist forces to prepare for an attack. Phase III began February 11 as the battalions moved away from the starting point at Phase Line Red and fought PAVN units as they advanced. From the 16-23 February, the Marines continued to push south and established new FSBs while collecting large quantities of arms and ordinance. Though the Marines were successful, PAVN fire made it difficult to resupply and evacuate troops. After 1 March, the weather created problems again. The only helicopters equipped to fly in the weather were Marine helicopters. However, they still managed to carry out missions within three hours from the demand. When the 1/9th pulled out on 18 March, the operation concluded as one of the most successful high-mobility regimental-size action of the war.

Dewey Canyon II (In support of LAM SON 719)
Operation
Dates: 1/30/1971 - 3/6/1971
Combat Tactical Zone: I
Tactical Area of Operation: Quang Tri Province, Khe Sanh and the A Shau Valley

This operation was in support of LAM SON 719. Because the U.S. was not allowed to enter Laos with the ARVN during LAM SON 719, they conducted airmobile and aviation operations as well as tactical air and B-52 bomber support. At the beginning of operation DEWEY CANYON II, the 1st Brigade, 5th Infantry traveled down Route 9 to Khe Sanh. The road was secure 5 February. At the same time, the 101st Airborne feinted into A Shau Valley to distract the PAVN. Once the attack into Laos commenced, U.S. helicopters of the 2/17th Cavalry attacked weapons sites and troops columns and secured landing sites. Also, the U.S. provided logistical support and aritillery fire from Khe Sanh and the surrounding areas in South Vietnam. The U.S. helicopters even inserted ARVN divisions into Laos. Weather and antiaircraft fire hindered U.S. aid. Technically, DEWEY CANYON II concluded 7 February. However, U.S. involvement continued until the ARVN troops withdrew from Laos.

Combat Tactical Zone: I
Tactical Area of Operation: Quang Ngai Province; beginning at Duc Pho

This was an unsuccessful operation meant to trap the Communists in the Quang Ngai Province. The basic plan was to use a pincer movement to crush the Communists. The Mairnes landed northeast of Duc Pho. The buildup was slow to decieve the enemy into thinking that they would only strike against the coastal areas. However, as the operation developed the Marines encountered problems. The weather inhibited the B-52 raids and rain and the jungle slowed Marine progress on land. On the other side of the pincer movement, the 1st Cavalry made heavy contact with the PAVN. When the forces prepared to squeeze the pincer closed, the PAVN and VC forces escaped. The operation ended with most of the enemy casualties occuring during the first week. The delays DOUBLE EAGLE had experienced allowed the PVAN and VC to have time to escape. They were much quicker than the linear movements of the allied forces.

Tactical Area of Operation: Phnom Penh

This plan first developed when Khmer Rouge units closed in on Phnom Penh and it seemed imminent that Cambodia would fall in 1973. On August 15, 1973 the Cambodian Army stopped the attack. The Khmer Rouge began to take the towns and EAGLE PULL was only used to evacuate Americans and a few others. However, in April of 1975 the Khmer Rouge focused on Phnom Penh again. An area was designated Landing Zone Hotel by the Marine element sent in to prepare the city for evactuation. The operation began at 0850 on 12 April when a four-man Air Force team landed. It guided in a Ch-53 with the first element of the Marine security force. The Marine and Air Force helicopters evacuated 276 people: 82 Americans, 159 Cambodians, and 35 foreign nationals. The people were taken to U.S. Navy carriers in the Gulf of Thailand. By 1000 everyone had been evacuated with no casualties. Cambodia fell April 17, 1975.

Eastertide (Easter Offensive): An Loc
Operation
Dates: 4/2/1972 - 7/11/1972
Combat Tactical Zone: III
Tactical Area of Operation: An Loc

The attack directed at An Loc began on April 2 when the PAVN feinted along the Cambodian border with the 24th Regiment. This regiment was comprised of VC divisions which were now mostly manned by PAVN regulars. On April 6, the 5th VC Division overran Loc Ninh. Only a few of the defenders from TF 52 survived to escape. The 5th VC Division continued to press on and overran the airfield at Quan Loi. Since the 7th VC Division had cut the supply route south, An Loc could only be resupplied by airdrop and helicopter.The 9th VC Division was supposed to take An Loc, but they delayed for a week after the 5th attacked because they were waiting for supplies. This saved An Loc. The 21st ARVN Division and the 1st Airborne Brigade were sent in to reinforce the 5th ARVN Division in defending the city. The 21st ARVN Division attacked the 7th VC Division and the 1st Airborne Brigade took "Windy Hill". The 9th VC Division finally attacked on 19th and managed to sieze part of An Loc before they stalled on 23 April. Later in May, the 5th VC Division continued the attack, but failed to take the city because of the ARVN Divisions and U.S. air support. The U.S. strikes were planned by military advisor Maj. General Hollingsworth. The PAVN continued to try to take the city, but the ARVN managed to clear the city of PAVN. The siege ended on July 11. This was the conclusion of the Easter Offensive. The PAVN had been turned back while taking more than 100,000 casualties and losing much equipment. The PAVN commander Gen. Giap was taken from power and replaced with Gen. Dung. The PAVN did gain half of the northern provinces of Quang Tri , Thua Thien, Quang Nam and Quang Tin. However, they failed to take An Loc as their capital. Meanwhile the Allies were encouraged in the success of Vietnamization, even though it was obvious that ARVN forces depended heavily on U.S. advisors and airpower.

Eastertide (Easter Offensive): Kontum
Operation
Dates: 4/12/1972 - 7/14/1972
Combat Tactical Zone: II
Tactical Area of Operation: Kontum

This second prong of the Eastertide Offensive was meant to divide South Vietnam in two by cutting across the Central Highlands. This was much the same plan as in the battle of Ia Drang, except the PAVN nearly succeeded this time. The assault began on the 12th of April, and by the 15th the bases of Dak To and Tan Canh were surrounded and the outposts to the west of Kontum were overrun. On the 23 April, an attack on Tan Canh overran the base. The base at Dak To also fell as the 47th Regiment fled. The Airborne Division had been withdrawn to reinforce I Corps, leaving Kontum defenseless. Meanwhile, the PAVN had cut Highway 1, the main north-south supply route. The PAVN only had to capture Kontum in order to divide South Vietnam. President Thieu fired II Corps commander, Lt. Gen. Dzu, and replaced him with Maj. Gen. Toan. Colonel Ba, who commanded the 23d ARVN Division, was brought in to be in charge of the battle. He brought in his own three regiments and reorganized the defenses in Kontum. They turned back the PAVN attack on May 14 and continued to hold back the communists during the attacks over the next two weeks. U.S. supported ARVN actions with air strikes and antitank helicopters. On May 28, a counterattack cleared the city. Col. Ba was promoted to general by President Thieu on May 30. Though they had already halted the attempt to cut South Vietnam in two at Kontum, the ARVN continued to fight and recaptured the coastal towns in July. This ended the Easter Offensive in central Vietnam.

Eastertide (Easter Offensive): Quang Tri
Operation
Dates: 3/30/1972 - 9/16/1972
Combat Tactical Zone: I
Tactical Area of Operation: Quang Tri Province

There were several reasons why Giap launched Eastertide when he did: almost all the U.S. ground froces were withdrawn, after the rout in Laos it was assumed the South Vietnamese would crumble under a PAVN attack, and a defeat at this time would humiliate Nixon and possibly force him from office. On March 30 the PAVN, with a definate advantage, attacked the newly formed 3d ARVN Division. The PAVN front consisted of the 304th and 308th Divisions with the 325th, 320th, 312th, and 324B in reserve. The 3d ARVN Division was driven back and its 56th Regiment surrendered. Eventually the Division was forced into the city of Quang Tri. On 1 May Quang Tri was abandoned and the 3d ARVN Division ceased to exist. President Thieu fired the I Corps commander and sent Gen. Truong, the best general in South Vietnam, to Hue. He used the Marine Division to defend the north and northwest and sent the 1st ARVN Division to defend the west. Then on June 28, Truong, along with reinforcements from the Airborne Division, set out to retake Quang Tri Province. The ARVN were assisted by senior U.S. adviser in I Corps Maj. Gen. Koresen. The U.S. also provided massive firepower, including bomber strikes and naval gunfire. The counterattack routed six PAVN divisions and retook Quang Tri City on September 16. By the end of October I Corps had been stabilized and one prong of the Easter offensive had been halted.
