How South Vietnamese Fighters Beat Back A Communist Offensive in the Vietnam War’s Longest Battle

Near enemy sanctuaries north of the Demilitarized Zone and in neighboring Laos, Quang Tri province was a continuing battleground. North Vietnam’s Communist Celebration Politburo members known as it the “blazing entrance.” Immediately the previous citadel fortress in Quang Tri metropolis, the capital of South Vietnam’s northernmost province, is a memorial park devoted to the North Vietnamese Military’s 1975 victory over the so-called “Saigon regime and its imperialist allies.”

The city and citadel have been restored within the early Eighties when Communist Celebration Secretary Le Duan designated Quang Tri a “valiant revolutionary metropolis.” It’s a standard attraction for varsity kids, getting older NVA veterans and international vacationers. Tour guides extol the heroism of the citadel’s communist defenders throughout the 1972 Spring-Summer season Offensive and decry the tonnage of American bombs dropped, calling it “wanton desecration.”

They don’t inform vacationers that the NVA overran the citadel on Might 1, 1972, and South Vietnam’s marines efficiently recaptured it 5 months later.

The assault to oust the NVA from Quang Tri metropolis was the longest single battle of the Vietnam Conflict—lasting 81 days, June 28-Sept. 16, 1972.

The opening salvo of North Vietnam’s offensive occurred on March 30, the Thursday earlier than Easter. Generally known as the Easter Offensive, it was the most important offensive of the warfare. The communists attacked with typical giant military models aiming for a decisive victory, eschewing the guerrilla and small-unit fighters beforehand used to attract out the battle and put on down the Individuals till they uninterested in the warfare and left. The protracted battle technique was discarded in favor of a “go-for-broke” gamble to decisively defeat the Military of the Republic of Vietnam and topple President Nguyen Van Thieu’s authorities.

The Communists’ “Go For Broke” Land Seize

NVA forces stormed throughout the DMZ and out of Laos alongside Freeway 9, heading for the previous imperial capital of Hue, the cultural hub of South Vietnam—the primary of three assaults in numerous areas of the nation. At daybreak on April 3, the NVA attacked firebases within the Central Highlands, a precursor to hanging Kontum metropolis with the last word objective of severing the nation at its midsection. Farther south 4 days later, within the space round Saigon, the NVA overran Loc Ninh, a well-defended outpost on the Cambodian border, and encircled An Loc, solely 60 miles from the capital.

The northern NVA juggernaut, 30,000-40,000 troops from three battle-toughened divisions (the 304th, 308th and 325C), accompanied by 200 tanks and air protection batteries, struck a thinly stretched brigade of the Vietnamese marine corps and the ARVN third Division. The commander of South Vietnam’s forces within the northern provinces, Lt. Gen. Hoang Xuan Lam, head of the military’s Da Nang-based I Corps, disregarded intelligence studies indicating that enemy had massed giant formations throughout the DMZ and directed a rotation of troops between two third Division firebases on March 29. His ill-timed order added to the turmoil when the NVA attacked the following day.

The South Vietnamese marines and the third Division manned positions simply south of the DMZ and within the western foothills. All have been underneath heavy assault on Easter Sunday, April 2, when a catastrophe occurred. ARVN Lt. Col. Pham Van Dinh, commander of the third Division’s 56th Regiment, surrendered his total unit and Camp Carroll, a former U.S. Marine Corps firebase. Dinh made no try to destroy giant ammunition shares or disable greater than 20 artillery items, together with 4 175 mm weapons.

Two U.S. Military regimental advisers, Lt. Col. Invoice Camper and Maj. Joe Brown, despatched a terse radio message stating they have been leaving. For safety causes they didn’t say the 56th Regiment was surrendering en masse. A just lately arrived lieutenant colonel, removed from the motion, despatched a frantic order: “Keep at your put up!”

He didn’t perceive that the judgment of advisers on the bottom was to be accepted with out query. Camper and Brown disregarded the command, prevented seize and escaped aboard a U.S. Military CH-47 Chinook transport helicopter piloted by Capt. Harry Thain, who obtained a Silver Star for the daring rescue.

The lack of Camp Carroll precipitated a basic withdrawal to positions close to the city of Dong Ha. South Vietnamese delaying actions offered some respite, and U.S. airstrikes slowed the invaders. Nonetheless, makes an attempt to ascertain a cohesive protection have been annoyed by I Corps commander Lam’s flurry of conflicting and uncoordinated orders. On April 28, Dong Ha fell. Three days later Quang Tri metropolis was deserted by disheartened, retreating troops.

Freeway 1 main out of city was plagued by the flotsam of warfare as troopers and civilian refugees fled south.

Panic ensued when the NVA fired on the columns. Wounded have been left the place they fell. Automobiles of each sort have been deserted. The leaderless rabble, a mixture of troopers and civilians, streamed into Hue and created chaos with drunken rampages and looting. The South Vietnamese marines retained their self-discipline and blocked the NVA advance with a steadfast defensive position alongside the My Chanh River, 15 miles from Hue.

The early communist successes strengthened the optimism of Politburo warfare hawks and marginalized members who had recommended warning. Le Duan, chief of the militant faction, was adamant that the political local weather in the US would stop a robust response from President Richard Nixon as a result of 1972 was a presidential election yr and the American public was seen as warfare weary. That was a gross misreading of the U.S. president.

At this level within the warfare, nevertheless, the choices for a robust U.S. response have been restricted. On April 30, 1972, there have been 68,100 American troops in Vietnam, down from a excessive of 543,100 in April 1969. That yr the Nixon administration initiated a Vietnamization program, which regularly withdrew U.S. troops whereas shifting floor fight obligations to the South Vietnamese. Solely two U.S. fight brigades remained, one in northern South Vietnam and one within the Saigon area, though their primary mission was defending U.S. air bases and logistical amenities.

Nixon dominated out reintroducing floor troops however retaliated with air energy. He dispatched further plane to Southeast Asia, resumed bombing “up north” and ordered the mining of North Vietnam’s seaports. Finally, 206 B-52 bombers and greater than 800 jet fighters, U.S. Air Drive and carrier-based plane, have been accessible for the combat. But in early Might, South Vietnam was in grave peril.

South Vietnamese Forces Rebound

The lack of Quang Tri and rioting in Hue satisfied Thieu that Lam needed to go. The president changed him with Lt. Gen. Ngo Quang Truong, commander of the Mekong Delta forces and regarded the nation’s greatest soldier. Truong and trusted assistants arrived at I Corps in lower than 24 hours.

He set about restoring order, enhancing defenses and planning a counterattack.

The brand new commander set the tone when he moved the I Corps primary command from Da Nang to Hue’s citadel, which had been a small ahead command put up manned by only a few officers and U.S. advisers. Lam visited the put up however all the time returned to his Da Nang headquarters for a day tennis match and dinner at residence. Officers assigned to the First Regional Help Command, the I Corps advisory crew, known as Lam “the absentee warlord.”

The My Chanh River line wanted reinforcement. Truong appealed to Thieu for added troops. On Might 8, the 2nd Airborne Brigade arrived and strengthened the marine line. Two weeks later, the third Airborne Brigade and the division headquarters have been flown to Hue. One of the best models—the Marine Division, the Airborne Division and the ARVN 1st Division—have been now underneath Truong’s command.

A stabilized entrance allowed the overall to turn out to be extra aggressive. Brigade 369 of the South Vietnamese marines initiated a two-battalion airmobile assault within the NVA rear simply south of Quang Tri metropolis. Two days later, on Might 15, the ARVN 1st Division retook the previous U.S. firebase Bastogne, strengthening the western strategy into Hue. South Vietnamese troops continued to battle their adversary, and American advisers used U.S. airstrikes with devastating effectiveness.

The I Corps counteroffensive to push the enemy again throughout the DMZ, code named Lam Son 72, went by way of a number of iterations. Thieu directed Truong to recapture Quang Tri metropolis, the one provincial capital in enemy fingers, earlier than advancing farther north. The city had no strategic worth, and Truong wished to bypass it, destroy NVA models and retake misplaced terrain, however the president’s order condemned the airborne and marine divisions to a bloody city brawl.

Elaborate deception measures have been employed to confuse the enemy concerning the time and placement of the assault. A parachute drop and an amphibious touchdown within the enemy rear have been two ruses that have been “leaked.” The deceptions, nevertheless, weren’t significantly efficient as a result of the NVA headquarters within the area obtained detailed details about the offensive from a spy on the I Corps employees.

A “Bloody Combat”

Lam Son 72 kicked off on June 28 when marines and paratroopers made an evening assault throughout the My Chanh River. Regardless that the plan had been compromised, they confronted restricted resistance. Inspired, senior ARVN officers anticipated to safe Quang Tri metropolis in 9 days. The projection was wildly off the mark.

The advancing troops have been aided by B-52 strikes, large air assist, U.S. naval gunfire and an airmobile assault by two battalions of South Vietnamese paratroopers and two battalions of Vietnamese marines, who landed behind the primary line of resistance. Even so, the Airborne Division took every week to achieve the outskirts of town. The measured tempo gave the enemy time to fortify the citadel. In-built 1824, the fort’s 4 sides measured 1,640 ft in size and have been all protected by a large moat. The thick brick partitions have been practically 30 ft excessive with a tower at every nook of the sq..

The Airborne Division commander, Lt. Gen. Du Quoc Dong, ordered the 2nd Brigade, consisting of three battalions of two,000-plus paratroopers, to take the city. Col. Tran Quoc Lich assured the overall that his brigade would do it rapidly and stocked bottles of classic champagne in anticipation of a victory celebration. Regardless of these assurances, Lich insisted on a cautious advance.

Maj. Le Van Me, an awfully succesful officer who commanded the brigade’s lead unit, the eleventh Airborne Battalion, knew Lich’s warning had value his battalion the initiative. Me’s U.S. adviser, Capt. Gail “Woody” Furrow, advised one other adviser: “We had ’em on the run! We must always bypass that city [Quang Tri] and head to the DMZ.”

The NVA commander within the area, Lt. Gen. Tran Van Quang, knew Thieu would do no matter it took to recuperate the provincial capital. To make sure a bloody combat, he shifted a number of infantry regiments into the citadel and used one other to assemble fortifications inside within the metropolis. Mortars and artillery tubes, significantly Soviet-made 130 mm area weapons, have been repositioned to offer most fireplace assist. The 130 mm weapons despatched 70-pound projectiles about 17 miles, effectively past the vary of the 105 mm and 155 mm howitzers on the South Vietnamese facet. NVA artillery and mortars inflicted the majority of the South Vietnamese casualties.

The 2nd Airborne Brigade assault commenced on July 10. Two battalions, the sixth and the eleventh, attacked from the south, whereas the fifth Airborne Battalion made the primary thrust from the northeast. The fifth and sixth Airborne battalions, which had arrived on June 25, have been understrength from combating in An Loc from April by way of mid-June. Capt. Earl Isabell, an adviser with the fifth Battalion, later stated: “We have been designated the primary assault however weren’t given further troops. We wanted a number of extra firms. New recruits had simply arrived however have been barely skilled. Plus, skilled leaders misplaced in An Loc had not been changed.”

“We have been at a hell of a drawback.”

The sixth and eleventh Airborne battalions gained footholds within the outskirts of town, however the NVA fought from home to deal with, giving floor solely grudgingly. Progress was measured in yards and buildings seized. The Marine division’s 1st Battalion launched an airmobile assault a couple of mile northeast of Quang Tri metropolis the morning of July 11 to cease visitors on Route 560, the communist defenders’ primary provide line, paralleling the Thach Han River. The battalion was transported by 34 U.S. Marine Corps helicopters and escorted by six U.S. Military Cobra assault helicopters.

The operation was supported by naval gunfire and B-52 strikes however nonetheless confronted heavy opposition. A hail of small-arms fireplace and SA-7 surface-to-air missiles greeted the helicopters. One CH-53 Sea Stallion and two CH-46 Sea Knight helicopters carrying South Vietnamese marines have been shot down. One chopper inadvertently landed close to a well-camouflaged NVA T-54 tank. A Cobra armed with anti-tank missiles knocked out the tank.

Maj. Nguyen Dang Hoa, commander of the first Battalion, and his adviser, U.S. Marine Capt. Lawrence Livingston, led assaults on July 11 that destroyed NVA fortifications blocking the advance. Livingston was awarded the Navy Cross for his gallantry. The battle continued for 3 days. By July 14, Route 560 was closed to enemy visitors. The NVA needed to discover an alternate solution to resupply its troops in Quang Tri.

The fifth Airborne Battalion made the primary assault on the night time of July 11. Preparatory artillery fireplace and 18 U.S. Air Drive sorties softened the citadel’s fortifications. However, the NVA defenders stopped the fifth Battalion in need of the citadel wall. Pleasant losses have been 25 useless and greater than 100 wounded.

A ban on U.S. airstrikes throughout the metropolis was instituted on July 15 as a result of Thieu wished Quang Tri recaptured with out American help. He was perturbed by studies that U.S. air energy had saved the day at An Loc and Kontum. Over Truong’s objections, an imaginary circle was drawn across the metropolis. U.S. airstrikes have been prohibited inside that space.

Like “Berlin in 1945”

The NVA, not content material to stay on the defensive, staged assaults to disrupt the efforts of ARVN models to coordinate their operations. It attacked the fifth Battalion on July 15 and nearly overran the command put up. For an unexplained purpose the assault was halted when success was throughout the NVA’s grasp. Two days later, the same assault struck the sixth Battalion, leading to hand-to-hand fight earlier than the North Vietnamese withdrew.

ARVN paratroopers pressed ahead, however features have been restricted and casualties mounted. The communists spared no sources to assist their protection as a result of holding Quang Tri was Hanoi’s prime precedence. Though Route 560 was blocked, ferries on the Thach Han River shuttled males, provides and alternative gear to the citadel, guaranteeing that the NVA maintained its numerical benefit. In the meantime, the Saigon authorities, scraping the underside of the personnel barrel, struggled to maintain up with requests for replacements.

The 2nd Airborne Brigade commander was directed to launch one other assault. This time the fifth Battalion was strengthened with two further firms from the elite 81st Airborne Ranger Battalion and a tank platoon. Earlier than the night time assault on July 23, a U.S. Air Drive F-4 Phantom was permitted to drop a 2,000-pound laser-guided bomb on the citadel’s northeast rampart, permitting the fifth Battalion to surge into the fortress. When daylight got here, the U.S. air restriction was once more imposed, and the South Vietnamese air power was known as upon to assist broaden the penetration. One airplane by accident dropped three 500-pound bombs amid the paratroopers, killing 45 and significantly wounding 100. The fifth Battalion was compelled to withdraw, ending the assault.

The 2-week combat annihilated the 2nd Airborne Brigade. The fifth Battalion was the toughest hit. The 600-man unit suffered 98 killed and 400 wounded. The opposite two battalions have been in no higher form. 4 of six American advisers have been wounded and hospitalized.

The Vietnamese Marine Division relieved the Airborne Division on July 27. One U.S. Marine adviser was startled by what he noticed at Quang Tri.

“The as soon as affluent metropolis resembled Berlin in 1945. Artillery and bomb craters have been all over the place. Most buildings have been fully destroyed. Solely the shells of sturdy buildings have been nonetheless upright.”

Most marines believed they’d rapidly prevail the place the paratroopers had failed. Their optimism was quickly dashed when the preliminary assault floundered after working up towards an entrenched, numerically superior power. U.S. Marine Maj. Richard Rothwell, an adviser with the Vietnamese Marine fifth Battalion, blamed a part of the issue on the Airborne Division’s failure to safe the marines’ left flank. A number of previous forts west of Freeway 1 have been manned by the NVA and stated to be firing on the advancing marine models. Earlier, Me, the eleventh Airborne Battalion commander, had acknowledged that the forts have been too distant to hinder an advance alongside the axis utilized by the marines.

Regardless, the I Corps employees did not assign accountability for the forts and set up precise boundaries between the 2 divisions. These have been main oversights in typical warfare’s customary working procedures, a results of years of small-unit operations and the corps employees not often working in a tactical atmosphere.

An assault on Aug. 3 additionally slowed down. Thieu was compelled to elevate restrictions on U.S. airstrikes inside Quang Tri, however that call made little distinction because the battle developed into duels that pitted South Vietnamese artillery and U.S. airstrikes towards NVA artillery. The Marine Division merely didn’t have adequate forces to beat the enemy. Brig. Gen. Bui The Lan, the division commander, wanted help.

All through August house-to-house combating and continuous artillery barrages brought about extra South Vietnamese losses. Since March 30, the 15,000-strong Marine Division had suffered 1,358 males killed and 5,500 wounded. Combating took the same toll on their U.S. advisers. In early July, the Marine Advisory Unit needed to make an pressing request for 9 officers to interchange casualties.

Lan’s repeated pleas for extra troops have been answered on Sept. 8, when the three battalions of the first Ranger Group relieved Marine Brigade 147 north of town, liberating extra battalions for the assault. Lan now had six battalions, 4 within the south and two within the north, to decide to the duty. He drew a boundary by way of the center of the citadel, putting Brigade 147 within the north and Brigade 258 within the south. The sixth Battalion was directed to assault from the southeast.

To attract the enemy’s consideration away from Quang Tri, the U.S. seventh fleet organized a pretend amphibious touchdown. The ninth Marine Amphibious Brigade went by way of all of the motions, together with false radio visitors, reconnaissance of touchdown seashores and embarking 400 ARVN rangers aboard U.S. touchdown craft. On Sept. 9, naval gunfire, tactical air sorties and a B-52 bomb strike pummeled the seashore due east of Quang Tri metropolis. When the bombing stopped, NVA troops moved out of their bunkers to confront the touchdown forces. They have been caught in a barrage of naval gunfire and sustained heavy losses. Amphibious automobiles and U.S. Marine helicopters approached the shoreline however turned again in need of the seashore.

A Laborious-Earned Victory

Whereas the ninth Marine Amphibious Brigade held the enemy’s consideration, the assault on the citadel started. The NVA had responded to the seventh Fleet menace by repositioning a few of its artillery, which diminished its fireplace on the attacking brigades. The South Vietnamese marines nonetheless confronted a troublesome combat. Rubble created by the bombardment made glorious defensive positions, and a labyrinth of NVA tunnels withstood a few of the fireplace.

On the night time of Sept. 9, Lt. Col. Do Huu Tung, commander of the sixth Battalion, despatched a reconnaissance patrol into the citadel. The patrol reported scanty opposition, and Tung launched an assault the next night. By first mild on Sept. 11, an organization lodgment was established contained in the southeast nook of the fortress. Tung rushed extra marines in. In the meantime, the first and 2nd battalions fought their solution to the Thach Han River, closing it off for enemy use. The NVA counterattacked, however the marines held on to their hard-earned features.

To the north, the third and seventh battalions cleared the world of communist forces. On the morning of Sept. 15, the third Battalion compelled its method into the citadel. The NVA started a large artillery bombardment to maintain the third Battalion and sixth Battalion aside, however the two models linked up by late afternoon.

On Sept. 16, at 12:45 p.m., the South Vietnamese flag was raised over the west gate of the citadel, signifying the tip of 138 days of NVA occupation.

The occasion was huge information worldwide, though some American newspapers, citing the casualties and the battered panorama, known as it a Pyrrhic victory. An intercepted communist dispatch blamed the NVA loss on American bombing: “The U.S. had schemed to degree this space and switch Quang Tri City right into a land of loss of life with no place for revolutionary forces.”

In South Vietnam, the restoration of the final provincial capital in enemy fingers was trigger for nice rejoicing. On Sept. 20, Thieu visited the Marine Division to congratulate the commander, officers and males. Promotions and decorations have been liberally awarded. U.S. Military Maj. Gen. Howard Cooksey, commander of the First Regional Help Command, advisable your complete Marine Division for the U.S. Presidential Unit Quotation. There isn’t a proof that the award was formally introduced.

Minor assaults to get rid of small pockets of resistance continued, however the battle traces between the 2 armies stabilized. An airborne adviser noticed: “They have been like two fighters within the 14th or fifteenth spherical. They might hardly do something however maintain on to one another.”

The South Vietnamese pleasure in rebuffing the most important offensive of the warfare was diluted by the phrases of the Paris Peace Accords, which have been signed on Jan. 27, 1973. The settlement allowed greater than 100,000 NVA troops to stay inside South Vietnam’s borders, putting the nation in an untenable place. The Thach Han River, 13 miles south of the DMZ border established by the 1954 Geneva Accords, grew to become the brand new boundary between the 2 Vietnams.

The truce gave the North Vietnamese time to reconstitute their battered military. A hostile U.S. Congress added to South Vietnam’s drawback by lowering army support, and Nixon, battered by the Watergate scandal, resigned in shame in August 1974. In early 1975, North Vietnam resumed its army marketing campaign to overcome the South. The previous revolutionaries in Hanoi have been certain the US wouldn’t intervene. This time they have been proper.

On March 19, 1975, the NVA overwhelmed the ARVN line alongside the Thach Han River. The defenders fell again, and the enemy instantly occupied Quang Tri metropolis, setting off a sequence response that swept up cities throughout South Vietnam. On April 30, 1975, NVA tanks crashed by way of the gates of Saigon’s presidential palace. The Republic of Vietnam ceased to exist.
