Battle of Dak To – The Most Brutal Combat of The Vietnam War

In the dense jungles of Vietnam, a harrowing battle unfolded, etching its name into the annals of history. The Battle of Dak To, considered one of the most brutal combats of the Vietnam War, saw relentless fighting and unimaginable courage. Taking place in the Central Highlands, this fierce encounter pitted U.S. and South Vietnamese forces against the North Vietnamese Army in a struggle that tested the limits of human endurance. But what drove these soldiers to push beyond their breaking points in such a merciless conflict? Stay with us as we delve into the full narrative of the Battle of Dak To.

The Deadly Battle of Hill 1338

In the early stages of the Vietnam War, the United States established CIDG camps along South Vietnam’s borders. These camps served a dual purpose: monitoring enemy forces such as the People’s Army of Vietnam, PAVN, and Viet Cong, while providing aid and training to the Montagnard villagers caught in the conflict’s crossfire. One notable camp near Dak To Village and airstrip became a focal point from 1965 onward, when it also became a base for the clandestine MACV-SOG group. Their mission: gathering intelligence on the Ho Chi Minh Trail in Laos.

However, by 1967, challenges emerged as the camp faced mortar attacks, prompting Colonel Jonathan Ladd’s astute leadership. He identified the source of the attacks, cautioning Major General William R. Peers against sending troops due to the imminent dangers. The rugged terrain around Dak To, marked by towering mountains and dense forest, made troop movement predominantly foot-based, with limited helicopter landing zones due to the harsh weather conditions fluctuating between scorching days and chilly nights.

In January of 1967, MG Peers stepped up to defend western Kontum Province, gearing up for what was ahead before the rainy season hit. Then, in May, Operation Francis Marion kicked off under his command. The 4th Infantry Division, alongside the 25th Infantry Division near Saigon, played a crucial role during these intense operations.

By mid-1967, the PAVN attacks in western Kontum Province were on the rise, indicating a shift in their strategy. Peers wasted no time implementing new tactics to ensure his units didn’t fall prey to isolation or get overwhelmed in the challenging terrain, which somewhat leveled the playing field in terms of firepower. One of his game-changing rules was keeping battalions together instead of splitting them into smaller groups for enemy searches. Even if smaller units had to venture out solo, they were never to stray more than 1 kilometer or 1 hour’s march apart, with immediate backup on standby if they made contact with the enemy. These strategic adjustments significantly contributed to reducing casualties for the 4th Infantry Division.

In response to escalating enemy activity, Peers urgently called for reinforcements. On June the 17th, Brigadier General John Deane swiftly dispatched two battalions from the 173rd Airborne Brigade to kick-start Operation Greeley in the Dak To region. Plunging into the dense, jungle-clad mountains, the 173rd, previously stationed near the Bien Hoa Airbase, had been combating primarily VC guerrillas. Despite Colonel William J. Livsey’s cautionary words regarding the formidable PAVN regulars in the highlands, the paratroopers pressed forward undeterred.

On June the 20th, Company C of the 2nd Battalion, 503rd Infantry Regiment, made a grim discovery, uncovering the remains of a missing CIDG unit on Hill 1338 south of Dak To. With Company A support, they ascended the hill and secured their position for the night. However, at 6:58 the following morning, Company A encountered a fierce ambush by the PAVN 6th Battalion, 24th Regiment, while advancing along a ridge. Despite orders for Company C to provide assistance, the challenging terrain and thick foliage impeded their rapid response.

During the intense battle, Company A faced challenges with artillery support being limited by poor visibility. The enemy, employing close-range tactics known as belt grabbing, made it difficult for U.S. forces to effectively use artillery and air strikes. Despite enduring continuous attacks throughout the day and night, Company A suffered significant losses, with 76 men killed and 23 wounded out of a total of 137. Surprisingly, the enemy’s casualties were much lower, with only 15 confirmed dead.

The aftermath of the battle was marked by discrepancies in casualty counts. While U.S. headquarters claimed high numbers of enemy casualties, the 173rd report presented a different figure. Company A soldiers, however, estimated a much lower enemy death toll. The heavy losses among American troops prompted discussions about accountability, with some advocating for disciplinary action. The commander and junior officers of Company C, known for their cautious approach during the engagement, were eventually reassigned to other units as part of the response to the situation.

The Battle of Kontum

Following the devastating loss of Company A, MACV swiftly responded by dispatching additional troops. On June the 23rd, the 1st Battalion from the 1st Air Cavalry Division arrived, reinforcing the efforts of the 173rd. The subsequent day saw the Army of the Republic of Vietnam 1st Airborne Task Force and the 3rd Brigade from the 1st Air Cavalry Division mobilized for a search-and-destroy mission in the north and northeast of Kontum.

Meanwhile, General Deane orchestrated troop movements west and southwest of Dak To, specifically targeting the 24th Regiment. Things escalated when the 4/503rd Airborne Infantry established a strategic base on Hill 664. Their encounter with enemy forces on July the 10th was intense, marked by heavy attacks. Remarkably, they stood their ground, and by morning, the PAVN forces retreated, leaving casualties on both sides.

The relentless pressure from PAVN on CIDG outposts necessitated the deployment of the ARVN 42nd Infantry Regiment. This culminated in a fierce battle near Dak Seang on August the 4th involving the ARVN Airborne. Notably, the 8th Airborne Battalion faced prolonged attacks and casualties before prevailing over the PAVN forces.

In mid-August, the situation shifted as enemy contacts dwindled, hinting at a possible retreat. Many ARVN and Airborne units headed back for some well-deserved rest. General Deane then handed over command to Brigadier General Leo H. Schweiter on August the 23rd. While some battalions were deployed to safeguard the rice harvest, others continued scouring the Toumorong Valley until wrapping up operations in October.

Around early October, American intelligence picked up on North Vietnamese movement from Pleiku to Kontum Province, significantly bolstering local troop numbers to almost a full division. Responding to this, the 4th Infantry began relocating battalions to Dak To for Operation MacArthur. By October the 29th, the 4/503rd Airborne Infantry rejoined the efforts, dispatched to Ben Het CIDG Camp to fortify the construction of Fire Support Base 12.

By November the 2nd, according to the official history of the North Vietnamese military, their actions were part of a strategy to ramp up activities, provide respite to local forces, and enhance their combat skills. An intriguing turn came on November the 3rd when Sergeant Vu Hong from the North Vietnamese 6th Regiment defected, sharing crucial insights with the South Vietnamese and American forces. He detailed the positions and plans of the North Vietnamese troops at Dak To and Ben Het, located about 18 km apart.

The North Vietnamese had concentrated around 6,000 troops there, predominantly from the 1st Division, the 66th Regiment poised for a southwest assault on Dak To, with the 32nd Regiment moving southward to block counterattacks against the 66th. Meanwhile, the 24th Regiment positioned itself northeast of Dak To to thwart potential reinforcements from that direction. The 174th Regiment, positioned to the northwest, stood prepared for potential combat engagements, supported by artillery from the 40th Artillery Regiment. Their objective was clear: seize control of Dak To and neutralize a sizable contingent of American forces.

These actions were part of a broader strategic initiative orchestrated by North Vietnamese leadership, particularly under General Nguyen Chi Thanh in Hanoi. Their strategic aim: to engage and decisively impact a significant U.S. presence, prompting further deployment of American troops to the Central Highlands. The North Vietnamese meticulously prepared for this campaign, fortifying their positions with robust defenses, including bunkers and trenches strategically positioned. Their meticulous planning involved extensive stockpiling of essential supplies and ammunition, ensuring that they were well equipped for prolonged combat engagements.

As the conflict unfolded, on the 4th and 5th, Schweiter received directives to relocate his brigade back to Dak To. Initially, the focus was on establishing a secure base and enhancing the safety of Ben Het. Subsequently, efforts were directed towards locating the headquarters of the 66th Regiment. Concurrently, reinforcements from the 4th Infantry Division, two battalions from the 1st Cavalry, and ARVN soldiers converged on the area. The village and airstrip evolved into a substantial base, facilitating coordination and support for a coalition of U.S. and ARVN troops as they braced themselves for a pivotal confrontation.

Split Decisions in the Face of Danger

In early November, the new operation kicked off with intense action. On November the 3rd, elements of the 4th Infantry encountered fortifying positions of the PAVN. The following day, the 173rd faced similar challenges. American and ARVN troops engaged in systematic combat across the rugged Highlands. They meticulously scoured the terrain on foot, discovering entrenched PAVN positions, deploying significant firepower, and launched assaults to dislodge the entrenched enemy. The PAVN fiercely resisted each encounter, inflicting casualties on American forces before retreating.

To bolster artillery support, the 4/503rd Airborne Infantry was tasked with securing Hill 823, located south of Ben Het, as Fire Support Base 15. Despite being under strength, 120 soldiers from Company B were airlifted in. Following air strikes and artillery bombardment, Company B landed without immediate opposition but soon encountered the PAVN presence. A fierce battle ensued throughout the night, culminating in the PAVN’s withdrawal, albeit with significant casualties. Tragically, nine soldiers from Company B perished and 28 were wounded.

The following day, Lieutenant Colonel David J. Schumacher’s 1/503rd assumed control from Company B. Despite cautionary advice, Schumacher divided his unit into two task forces. Task Force Black engaged the PAVN responsible for the earlier attack on Company B, resulting in an ambush and intense combat. Task Force Blue, along with Company C from the 4/503rd, rushed to support amidst heavy enemy fire but successfully navigated through. U.S. losses amounted to 20 killed, 154 wounded, and two missing.

During the aftermath, the leader of Task Force Black initially reported 80 PAVN casualties but revised the count to 175 after further assessment. Tensions arose between him and Schumacher regarding the recognition of a soldier’s heroic sacrifice, eventually leading to the soldier receiving the Medal of Honor. The PAVN claimed 32 casualties from the engagement.

At the same time, the PAVN attacked three companies of the 3/8th Infantry on Hill 724. They shelled and then charged, leaving 18 Americans dead and 118 wounded. The 4th Infantry said 92 PAVN died. An article said over 500 PAVN and 67 U.S. troops died.

On November the 12th, the PAVN attacked the Dak To Airfield with rockets. They destroyed planes and caused big explosions but could not take the airfield. The Allied forces’ quick response stopped the PAVN’s offensive and put them on the defensive. The PAVN started retreating, and the Americans and ARVN faced strong resistance.

To avoid another attack on their camp, the 3/12th Infantry was told to capture Hill 1338, which gave a clear view of Dak To just 6 km away. It took the Americans 2 days to climb the steep hill and enter a complex of bunkers connected by field telephones.

Meanwhile, after dealing with the enemy who attacked Task Force Black, three companies of the 1/503rd moved southwest to take over Hill 882. They were accompanied by around a dozen civilian journalists. On November the 15th, as the lead company reached the top of the hill, they found bunkers linked by phone wires. They were then attacked, and the rest of the Americans hurried to defend the hilltop. The enemy poured gunfire and launched attacks, resulting in casualties.

The U.S. commander asked for helicopters to evacuate the severely injured, but Colonel Schumacher insisted on evacuating the civilians first. By November the 19th, the U.S. battalion had seven dead and 34 wounded, while the enemy had 51 casualties.

At the same time, Company D, the 4/503rd, was clearing roads near Ben Het with CIDG Mike Force. During an artillery call, two rounds hit the company by mistake, killing six Americans and three CIDG members and injuring others.

The ARVN units were also active in the Dak To area. On November the 18th, on Hill 1416, they encountered the well-prepared PAVN 24th Regiment. The elite ARVN 3rd and 9th Airborne Battalions joined the fight, eventually taking the hill on November the 20th after tough battles that resulted in casualties on both sides.

U.S. intelligence reported that the new 174th PAVN Regiment had moved past Ben Het and occupied a hill near the border to cover the withdrawal of other PAVN units. BG Schweiter ordered his 2nd Battalion to take this hill after hearing about heavy resistance faced by a Special Forces Mobile Strike Force company in the area.

The Battle That Shook the 173rd Airborne Brigade

On the morning of November the 19th at 9:43, things were heating up as three groups of soldiers from the 2nd Battalion of the 503rd Parachute Infantry Regiment were gearing up for action on Hill 875. Picture this: soldiers from Company C and D leading the charge up the hill, while two groups from Company A formed a strategic advanced reserve formation that’s been a classic since World War I. Down at the base of the hill, the weapons platoon of Company A was busy prepping a landing zone, readying for what was about to unfold.

As they closed in within 300 m of the hill’s peak around 10:30, all hell broke loose. Machine guns rattled, rockets whizzed, and rifles crackled as the enemy, holed up in bunkers and trenches, unleashed a barrage of fire. Our American troops, determined to push forward, found themselves in a tight spot, pinned down by relentless small-arms fire and grenades. It was like something out of an action movie.

By 14:30, what started as a bold advance turned into a gritty retreat thanks to a well-planned ambush by the 2nd Battalion of the 174th Regiment. Amidst the chaos, Private First Class Carlos Lozada emerged as a hero, bravely defending his fellow soldiers’ retreat until his last breath. His actions didn’t go unnoticed, earning him the posthumous honor of the Medal of Honor.

Behind the scenes, efforts to resupply our troops with essentials like ammunition and water were in full swing, but the thick vegetation and ongoing skirmishes made it a Herculean task. Adding to the drama, attempts to airlift supplies were met with fierce resistance, with several helicopters meeting their fate in the line of duty.

On a tragic evening at 18:58, a heartbreaking incident unfolded as Marine Corps aircraft mistakenly dropped bombs on our battalion’s position. The aftermath was devastating, with numerous casualties, including brave soldiers and medics who were either injured or lost their lives.

The following day brought another daunting task as the 4th Battalion was called upon to relieve our comrades on Hill 875. The journey was perilous, marked by sniper fire and mortar attacks, prolonging our journey until nightfall when we finally reached our fellow troops.

The subsequent day was met with more challenges as both battalions launched a determined assault to capture the hill, facing relentless resistance and engaging in close combat. Despite enduring fierce air strikes and artillery bombardment, victory was hard-fought, with American forces seizing control of Hill 875 on November the 23rd, only to discover that the enemy had already retreated from their positions.

The toll of battle was heavy, marked by significant casualties and losses within the 173rd Airborne Brigade. However, amidst these adversities, the collective valor and resilience of our forces during these operations did not go unnoticed. It was through their unwavering dedication and combined efforts that the brigade was honored with the esteemed Presidential Unit Citation.

Assessing the Toll of Battle

In late November, the Vietnamese military moved back to their safe areas in Cambodia and Laos, unable to completely defeat a large American military group but causing significant losses to the U.S. Army near Dak To. 376 American soldiers were killed or presumed dead, and 1,441 were injured. Additionally, 73 soldiers from the South Vietnamese Army lost their lives.

The intensity of the battle was shown in the weapons used: 151,000 artillery rounds, 2,096 air missions, and 257 B-52 air strikes were recorded. The U.S. Army conducted 2,101 helicopter missions, losing 40 helicopters.

There were disagreements about enemy casualties, with claims that the numbers were exaggerated. One commander reported losing 78 men but finding only 10 enemy bodies, while official reports claimed 475 enemy casualties. There were also conflicting reports about casualties from different sources. General William C. Westmoreland mentioned 1,400 enemy casualties, while others estimated between 1,000 and 1,400. Some commanders criticized the high number of friendly losses compared to reported enemy casualties.

General Charles P. Stone, who took over after the battle, criticized previous strategies and questioned the importance of certain locations like Hill 875. The Military Assistance Command, Vietnam, MACV, reported that most Vietnamese regiments were severely damaged and couldn’t continue their attack. Only one regiment, the 24th, fought in the Tet Offensive in January of 1968.

Some American units, like the 173rd Airborne Brigade and parts of the 4th Infantry Division, suffered heavy losses. Westmoreland believed they had defeated the enemy and limited losses in other areas. However, events showed that the Vietnamese achieved their objectives. By January of 1968, many American battalions had to move from cities to border areas.

After fights in the Central Highlands, the 173rd Airborne Brigade had to relocate to Tuy Hoa. In 1968, they moved again to Cam Ranh. Some believe this mirrored the Vietnamese strategy before the Battle of Dien Bien Phu in 1953. General Giap discussed the strategy, but Americans found it difficult to comprehend why Hanoi would fight so fiercely unless something significant like Dien Bien Phu was planned. This became evident when PAVN forces surrounded a Marine outpost at Khe Sanh in Quang Tri Province, resembling the situation at Dien Bien Phu.
