The Battle of Hamburger Hill was one of the fiercest battles of the Vietnam War.

The battle took place on Dong Ap Bia (Ap Bia Mountain) in the rugged, jungle-shrouded mountains along the Laotian border of South Vietnam. Rising from the floor of the western Ashau Valley, Ap Bia Mountain is a looming, solitary massif, unconnected to the ridges of the surrounding Annamite range. It dominates the northern valley, towering some 937 meters above sea level. Snaking down from its highest peak are a series of ridges and fingers, one of the largest extending southeast to a height of 900 meters, another reaching south to a 916-meter peak. The entire mountain is a rugged, uninviting wilderness blanketed in double- and triple-canopy jungle, dense thickets of bamboo, and waist-high elephant grass. Local Montagnard tribesmen called Ap Bia "the mountain of the crouching beast." Lieutenant Colonel Weldon Honeycutt, commander of the 3d Battalion, 187th Infantry (the "Rakkasans"), called it "Hill 937." The soldiers who fought there dubbed it "Hamburger Hill".

The battle

The fight on Hamburger Hill occurred during Operation Apache Snow, the second part of a three-phased campaign intended to destroy PAVN bases in the treacherous Ashau Valley. This campaign was the latest in a long series of attempts to neutralize the Ashau, which proved a persistent thorn in the side of the previous Military Assistance Command, Vietnam (MACV) commander, General William C. Westmoreland. Each effort met with results ranging in degree from ineffectual to disastrous. Lieutenant General Richard Stilwell, commander of XXIV Corps, resolved to succeed with his operation, however, and amassed almost two divisions of infantry and a daunting array of air power to ensure victory.

Leading the attack were five infantry battalions under Major General Melvin Zais, commander of the 101st Airborne (Airmobile) Division. Three units were American (the 1/506th, 2/501st, and 3/187th Infantry), and two came from the 1st Army of the Republic of Vietnam (ARVN) Division (the 2/1st and 4/1st ARVN). Colonel Joseph Conmy, commander of the 3d Brigade of the 101st Airborne, controlled the main effort. He characterized the operation as a reconnaissance in force (YUF). His plan called for each of the five battalions to "combat assault" into the valley by helicopter on 10 May 1969 and to comb its assigned sector for Vietnamese troops and supplies. If a battalion made heavy contact with the PAVN, Conmy would reinforce it with one of the other units. In theory, the Americans, utilizing helicopters, could reposition their forces quickly enough to keep the Vietnamese from massing on any one unit while an American force discovering an PAVN unit would fix it while the reinforcing battalion flew in to cut off the Vietcong's retreat and destroy it.

The American and South Vietnamese units participating in Apache Snow knew, based on existing intelligence and previous experiences in the Ashau, that they were in for a tough fight. Beyond that, however, they had little evidence as to the Vietcong's actual strength and dispositions. Masters of camouflage, the PAVN completely concealed their bases from aerial surveillance. When the PAVN moved, they did so at night along trails covered by triple-canopy jungle, again confounding observation from above. They effected their command and control mainly by runner and wire, leaving no electronic signature for the Americans to monitor or trace. Technology, therefore, provided scant assistance to the American battalion commander trying to "see the Vietnamese" during Apache Snow. He had to generate his own tactical intelligence. Patrols, captured equipment, installations, documents, and occasionally prisoners provided combat commanders with the raw data from which to draw their assessment of the Vietnamese order of battle and dispositions. Gathering this information took time and it took days to ascertain intelligence about the Vietcong's strength and dispositions.

At first, the battle went well for the American side. The American and South Vietnamese units experienced only light Vietnamese contact on the first day. However documents captured by Lieutenant Colonel Honeycutt's 3/187th Infantry indicated that the entire 29th PAVN Regiment, nicknamed the "Pride of Ho Chi Minh," was somewhere in the Ashau Valley. Past experience indicated the Vietnamese would resist violently for a short time and then withdraw as the Americans brought overwhelming firepower to bear against them. This was a familiar pattern in many of the larger encounters with the PAVN and in the previous Ashau battles. The big battles, such as Dak To and Ia Drang, where the Vietnamese offered prolonged, determined resistance, were rare. Considering this, Honeycutt anticipated his battalion would be able to handle whatever he found on Hill 937. As insurance, he prudently requested and received the brigade's reserve, his own Bravo Company. He intended to find the PAVN force located in his part of the valley and engage it before it could escape into Laos.

On 11 May, Honeycutt dispersed his Rakkasans and scoured the vicinity to the north and northwest of Ap Bia Mountain. His men swept west toward the nearby Laotian border and south up the north slope of the mountain itself. When Bravo Company made heavy contact with some PAVN late in the day, Honeycutt responded quickly by directing Cobra helicopter gunships, known as aerial rocket artillery (ARA), to support a hasty assault. Unfortunately, in the heavy jungle, the Cobras mistook the battalion command post for an PAVN unit and attacked and killed two Americans and wounded thirty-five, including Honeycutt himself. The friendly fire incident temporarily eliminated all battalion command and control of the battle and forced 3/187th to withdraw into night defensive positions. Bravo Company was separated from its objective, the summit of Dong Ap Bia, by less than 1,000 meters. The incident confirmed what Honeycutt already suspected, that there was a Vietnamese force on the mountain, However, the contact was serious enough for him to adjust his estimate of the Vietcong's strength from "a few trail watchers" to a reinforced platoon or even a company. The Rakkasans could still deal with a force that size, but they would have to concentrate to do so.

For the next three days, Honeycutt fought the mountain and the PAVN to bring his scattered companies together for a coordinated battalion attack. Despite the fact that, since the initial assault, no company was more than about 1,500 meters from the crest of the mountain, it took two days to consolidate the battalion for a three-company assault. Time and again, the American infantrymen found themselves hampered as much by the topography as by the North Vietnamese and Vietcong forces. The rugged terrain slowed dismounted movement to a crawl. Between 12 and 14 May, for example, Delta Company was virtually immobilized when it went down a steep ravine and was caught there by the Vietcong. In one grueling five-hour period, the company labored to advance a total of only 500 meters. The steep, mud-covered slopes, more than the Vietcong, kept this company from fulfilling Honeycutt's intent. In the end, the troops had to abandon their attack and withdraw the way they had come.

These three days were a period of intensely unpleasant "discovery learning" for Honeycutt and his men. Map reconnaissance and helicopter overflights did not indicate that his initial scheme of maneuver was impractical. It took Delta Company's three-day ordeal to do so. Though Honeycutt had a long and distinguished record as a combat commander in both Vietnam and Korea, he underestimated Ap Bia Mountain and the NVA facing him. Although his estimate of the Vietnamese strength was incorrect, his miscalculation was not immediately apparent to him or to any of the American leadership. It took three days of assaults by Bravo and Charlie Companies, each bloodily repulsed, before the situation became clearer. The Vietnamese were stronger than anticipated, much stronger than company strength, and they grew more powerful every night as they received reinforcements from Laos. The NVA commander's demonstrated tenacity and willingness to replace heavy losses indicated he intended to put up a stiff fight for Hill 937.

By 13 May, it had become clear to the brigade commander, Conmy, that Ap Bia Mountain contained more NVA than the 3/187th Infantry could handle alone. At midday, he decided to send 1/506th Infantry (the Currahees) north from their RIF area of operations to assist Honeycutt. This action conformed to the American tactic of maneuvering an uncommitted battalion to support a battalion in heavy contact. Hoping to cut off Vietnamese reinforcements to Dong Ap Bia, Conmy ordered the 1/506th Infantry to attack north, cross-country, to hit the NVA facing Honeycutt from the rear. Starting from positions that were only about 4,000 meters from Hill 937, Conmy could have reasonably expected the Currahees to be ready to provide support to 3/187th Infantry no later than the morning of 15 May. Yet it took 1/506th Infantry five and a half days, until 19 May, to reach Honeycutt. By the standards of dismounted movement routinely practiced by today's light infantry at the Joint Readiness Training Center (JRTC), 1/506th Infantry's pace was glacial. In one forty-hour period over 13-14 May, the battalion was able to cover only 1,500 of the 4,000 meters separating it from its objective on Ap Bia Mountain. Rough terrain and the ever-present Vietnamese snipers made the difference. Conmy and the 1/506th Infantry, like Honeycutt, learned the hard way that Ap Bia Mountain and the Vietnamese on it defied previous experience.

Treacherous terrain and well organized forces of Vietcong and Norther Vietnamese soldiers that knew how to exploit it continually threw off the tempo of American tactical operations at Hamburger Hill. Both airborne infantry battalions were "ground-bound" in the jungle, maneuvering at the pace of their foot soldiers. Not even the helicopter, the transcendent theme of American technological superiority in this war, offered much hope of speeding up maneuver. Steep gradients and dense vegetation provided few natural landing zones in the vicinity of the mountain. The rugged terrain also masked the NVA positions, making it nearly impossible to suppress Vietnamese anti-air units. Throughout the battle, unseen NVA soldiers maneuvered in the jungle around the American landing zones and shot down or damaged numerous helicopters with small arms fire and even rocket-propelled grenades. In fact, the dense terrain covered the movement of Vietnamese forces so completely that it created the effect of a nonlinear battlefield. The NVA continuously slipped behind the American lines, hitting logistical support landing zones (LZs) and command posts (CPs) no fewer than four times. This problem caused each company and battalion commander to leave a substantial portion of his force in the rear to cover his LZ and CP and ensure the flow of supplies, the evacuation of casualties, and uninterrupted command and control. In addition to securing their LZs, attacking companies had to provide for 360-degree security as they maneuvered, since the terrain prevented them from mutually supporting each other until the final assaults on the mountain. Even so, time and again, NVA platoon- and company-size elements struck maneuvering American forces from the flanks and rear as the Rakkasans and Currahees directed their attention toward the mountain top.

The effectiveness of U.S. maneuver forces was further constrained by the narrow trails along which the Americans advanced through heavy vegetation. For much of the battle, each of the attacking American companies assaulted on a squad or platoon front. Thus, at the point of attack, American squads and. platoons frequently faced NVA platoons and companies. To overcome this firepower disparity, the American infantrymen traditionally responded with artillery and close air support. With most small arms engagements on Hamburger Hill limited to tens of meters, however, American indirect fire support was severely restricted. Often, the Vietnamese were too close and the situation too fluid for units in contact to get timely, accurate supporting fires. In close combat, American infantrymen had to succeed with their own direct fire or, as frequently happened on Ap Bia, pull back and await artillery, close air support, and ARA. Even then, there was no guarantee that the artillery and close air would do the job. The dense jungle and wild, irregular contours of Ap Bia served to dampen the effects of American fire support, NVA bunkers were well sited to take advantage of these, contours and the jungle cover. Furthermore, bunkers were well built, with substantial overhead cover that withstood days of pounding. Over time, U.S. bombs and napalm stripped away the foliage and exposed the NVA's bunkers. But they were so numerous and so well constructed that they could not be destroyed by indirect firepower alone. Napalm and infantry recoilless rifle fire proved to be the weapons of choice for busting the bunkers.

Under these fluid conditions, battle command was decidedly decentralized. Though Honeycutt constantly prodded his company commanders to push on, he could to do little to direct their tactics as they fought through the jungle. Only in the closing days of the battle, when his companies maneuvered in close proximity over the barren mountain top, was he able to coordinate mutual support among his subordinates. Fire support for units in contact with the Vietnamese was also decentralized. Artillery, ARA, and close air support (with airborne forward air controller [FAC] assistance) were responsive to units down to platoon level. Yet in the evolving, often confusing, maneuver battle, it was inevitable that command and control of supporting fires suffered. Fighting on Ap Bia Mountain produced no fewer than five incidents of air-to-ground fratricide over a ten-day period. Pilots (and sometimes the FACs) were unable to distinguish friend from foe in the intense and confusing fighting around the mountain. In at least one incident, the pilots themselves became lost and attacked more than a kilometer off their intended target.

On 14 and 15 May, Honeycutt launched two coordinated battalion attacks against Ap Bia Mountain. Each day, he expected support from 1/506th Infantry, and when it failed to appear, he attacked alone. Honeycutt rightly believed that each day he left the North Vietnamese undisturbed on the mountain gave them more time to improve their defenses. Nevertheless, both attacks failed. Although Honeycutt's Bravo Company attacked to within 150 meters of the summit, Vietnamese fire, steep terrain, and rain combined to force the Rakkasans back down the slope. On 16 May, 1/506th Infantry attacked north toward Dong Ap Bia but was stopped after seizing Hill 916-still some 2,000 meters from its objective. With the two battalions so far out of supporting distance, the brigade commander ordered Honeycutt to wait for 1/506th Infantry.

Associated Press correspondent Jay Sharbutt learned of the ongoing battle at Ap Bia, travelled to the area and interviewed Zais. More reporters followed him to cover the battle.

The next day, 17 May, 1/506th Infantry attacked again but made little progress. Although the Currahees were still almost 1,500 meters from the top of Ap Bia Mountain, the brigade commander ordered a coordinated two-battalion assault for 18 May. With 1/506th Infantry attacking from the south and 3/187th Infantry attacking from the north, he hoped the Vietnamese would not be able to concentrate against either battalion. Fighting to within seventy-five meters of the summit, Delta Company, 3/187th Infantry, almost realized Conmy's wish. Unfortunately, with every officer in the company killed or wounded and over 50 percent casualties, the battle degenerated into an uncontrollable brawl, with NVA and GIs exchanging small arms and grenade fire within twenty meters of each other. Honeycutt committed three companies into the fray, coordinating their movements from a light observation helicopter. As they prepared for the final assault, however, a roaring thunderstorm washed over the battlefield, reduced visibility to nothing, and caused all firing to stop. Unable to advance in the torrential rains on a battlefield tamed into a quagmire, the Rakkasans reluctantly withdrew down the mountain again. The 1/506th Infantry met with heavy opposition for the first time in the battle, but its three converging companies managed nonetheless to get to about 1,200 meters of the top of Dong Ap Bia.

In view of the heavy casualties already sustained in the battle, Zais seriously considered stopping the attack on Dong Ap Bia. Although he was under great pressure from the unwanted attention of the press, he decided to continue the fight. Both his corps commander Lieutenant General Stilwell and the MACV commander, General Creighton Abrams, backed him. He decided to commit three fresh battalions- the 2/50 1st Infantry, 2/3d Infantry (1st ARVN Division), and 2/506th Infantry. The 3/187th Infantry's casualties to this point were staggering. Not counting replacements, Alpha and Bravo Companies had lost 50 percent of their original strength, while Charlie and Delta Companies had lost 80 percent. Furthermore, two of the four original company commanders were casualties, as well as eight of twelve platoon leaders. Considering these crippling losses, Zais initially decided to relieve the 3/187th Infantry with the 2/506th Infantry. Honeycutt, however, demanded that Zais allow the Rakkasans to take the mountain, and the division commander relented.

The Americans launched the final attack on Dong Ap Bia on the morning of 20 May 1969. The Rakkasans had been reinforced with a company from 2/506th. Infantry, and the division had airmobiled two additional battalions onto the battlefield. Ten days after the battle had begun, the 101st Airborne Division finally brought overwhelming combat power to bear against the NVA. The attack began with two hours of close air support and ninety minutes of artillery prep fires. Four battalions attacked simultaneously, and within two hours, 3/187th Infantry became the first battalion to reach the top of Ap Bia, Some of the Vietnamese chose to flee, but many fought in their bunkers to the end. The 3/187th Infantry finally secured Hill 937 about 1700 on 20 May.

Results and analysis

The ten day Battle of Hamburger Hill had cost 70 American dead and 372 wounded. To take the position, the Americans eventually committed five infantry battalions, about 1,800 men, and ten artillery batteries. In addition, the U.S. Air Force flew 272 attack sorties and expended more than 1 million pounds (450 t) of bombs and 152,000 pounds (69 t) of napalm.21 This massed firepower took a devastating toll on the NVA. The 7th and 8th Battalions of the 29th NVA Regiment were virtually wiped out. Over 630 dead NVA were discovered on and around the battlefield and many more undoubtedly covered the trails and draws leading back into Laos. Yet the repercussions of the battle were more political than military. Questions raised by the press concerning the necessity of the battle stirred controversy for weeks after the fighting stopped. These issues flared up again when the 101st Airborne quietly abandoned the hill to the Vietnamese in June. Eventually, the investigation into the Battle of Hamburger Hill reached Congress and led to a reappraisal of American strategy in Vietnam. And then the Hamburgers attacked. Those darn McDonaldites.
