Laos | The Secret War

After a six month delay and lots of preparations, my friend, Al Willner, and I were set to leave on our next adventure. This time the theme of our trips would be the CIA Secret War in Laos and the Vietnam War (or American War as it is called in Vietnam).

Coming along with us for the Laos portion and to Hanoi would be my daughter, Nabra. She had just had a very successful opening of her play "Memory Lane is a Desert Road" - I plan to do a blog on that experience as she put me down as co-playwright and it was a pretty intense and nerve wracking adventure of its own. on it's own.

We all met up in Los Angeles and flew to Vientiane arriving late at night on the second day of Bee Ma Lao (the Lao New Year).

As we proceeded into town, our hotel had cautioned us that it may take some time because of the New Year celebrations. The weather was warm and humid and all seemed pretty quiet until we entered the city. The taxi driver rolled up the windows and soon we were stuck in heavy traffic as we passed by bars and night clubs - pulsating with techno tunes and drenched people with water hoses and white face paint.

Day One | Vientiane

We met up for breakfast with my sister Juliet who had been on a tour through Cambodia and Vietnam. She had already been in Laos for a few days and had toured Luang Prabang and Vang Vieng and loved it.

Though Al had try to make arrangements for our trips in advance, visiting remote CIA Secret War sites had proved challenging. Initially we had planned to visit the huge CIA airfield at Long Tieng, but the adventure tour outfit Tiger Trails could not guarantee the road there would be passable. So after some research, Al had come up with an alternative site - the battle at Lima Site 85 in the remote northeastern mountains only a few miles from Vietnam.

After breakfast we headed out towards the Laos Tourist Information Center in hopes of arranging transportation and accommodations for our stay in Sam Nuea the next day. It was hot and humid and the streets were deserted after late night partying. Most everything was closed and so was the tourist office. So we would now just need to wing it when we arrived in Sam Nuea.

It took some time and negotiating as there were few people or vehicles in the streets, but we arranged for an all day tuk-tuk tour with driver, Phocon.

First stop was the eclectic Buddha Park some 22 kilometers away. As we were probably the only tourists making this trip in an open vehicle, we were the frequent target of Lao New Year celebrants who had not only water hoses in hand, but had also set up inflated baby pools along side the road and with large containers would throw water - sometime colored - at us. It was actually a lot of fun and was a nice way to cool down.

The park was created by priest-shaman Luang Pu Bunleua in 1958. The reinforced concrete statues and structures integrates elements of Hinduism and Buddhism with Bunleua own spiritual concepts. In 1975, he fled across the border to Thailand fearing repercussions from the communist Pathet Lao that took over the country. He created another similar park a few kilometers away on the other-side of the border. The Laotian government now runs the Buddha Park as a tourist attraction and public park.

With most sites being closed because of the holiday, we still tried to see if the Kaysone Memorial where the CIA ran their Secret War for 11 years and where the leader of the Communist Lao People's Revolutionary Party and former Laotian President Kaysone Phomvihane lived from 1975 until his death in 1992. Though the gates were open and we could see it through the trees, the Laotian guard would not let us onto the grounds.

After meeting some French travelers who highly recommended the Vientiane Art Museum (it was open), we decided to check it out. Though it was an art museum practically the only art work other than some immense paintings were hundreds of very impressive wood sculptures.

For dinner, we decided to check out restaurants along the Mekong River and had to run the gauntlet of water ready celebrants and were soon soaking wet. On the way back I used other pedestrians as blocks and successfully evaded most of the water bandits though I did get hit a few times.

Day Two | Sam Nuea

The Lani's House by the Ponds manager had managed to get us hotel rooms in Sam Nuea, but we still hadn't worked out transportation for either of our visits in the area as well as to Vietnam. We had checked on flights from Sam Nuea to pretty much anywhere and all were booked up for the next week, so we would definitely need to go overland from Laos to Hanoi.

After a pretty dramatic flight into the cloud covered mountainous region we arrived at the airport which has been newly built and is about 30 kms north of Sam Nuea. After a slow bus ride we arrived in town and checked into our unmarked hotel (it is listed as Ban Tai Hotel on Google Maps. But there was no sign outside indicating the hotel's name). Al had read that it is the hotel used by Communist party dignitaries who visit Sam Nuea. On the second day, a Chinese delegation was there accompanied by attractive Laotian women hosts in matching outfits.

At the Tourist Information Office (fortunately open), Nour Amr who spoke excellent English made a call and arranged for transportation with an English speaking driver to take us to Lima Site 85.

For the rest of the day, we explored the small town of Sam Nuea and visited the market.

Tomorrow we would head to Phou Pha Thi, a sacred mountain top where the United States Air Force set up a radar installation site manned by deep cover US Air Force personnel called Lima Site 85 to guide American bombing missions into North Vietnam and Laos during the Secret War.

Day Three | Lima Site 85

We had an early breakfast at 7am and got on the road with our driver, Meexay for the 67 km drive to Phou Pha Thi. Very scenic drive through river valleys and up mountain ridges and past villages. Meexay who is Hmong told me all about his people and family. Though only 34 years old he has six kids, and is quite the entrepeneur with a car rental and money exchange business.

After a two hour drive, we arrived at the base of the mountain. We registered at the military outpost, paid our 50,000 kip per person fee (about 2 1/2 dollars), and consulted with the local Lao Army representative. We had packed lunches and water for the ascent to the top of the 5,800 foot mountain. Though relatively high, there was no wind at the base of the mountain as we started what would turn out to be an 860 ft elevation gain for the little over a mile hike to the summit. Fortunately, a stairway had replaced the old ladder system and though hot and humid, we made good time to the top of the plateau area. Nabra who was concerned about a high-ish altitude hike scrambled up like a mountain goat.

The hike up to Lima Site 85 |

As we made our way up to the battle site we passed numerous bomb craters and even spied some spent shells next to the trail. Laos, though not at war with the United States, was used by the North Vietnamese to transport soldiers and equipment along the Ho Chi Minh Trail into South Vietnam.

In an attempt to stop and impede the flow of weapons and soldiers, US Air Force and Navy air missions carried out an immense bombing campaign called Operation Barrel Roll in the Kingdom of Laos from 5 March 1964 to 29 March 1973.

More than 580,000 bombing sorties dropped an estimated 2.5 million tons of ordinance including 270 million cluster submunitions. More bombs were dropped over Laos than all the bombs dropped during WWII combined. Laos is the most heavily bombed country in the world and continues to suffer between 50-100 casualties yearly (many of them children who mistake them for toys) from the nearly 80 million unexploded bomblets. There have been over 50,000 civilians casualties since the war with 20,000 occurring since 1973 (the end of the bombings).

It is estimated that one bombing mission was carried out every 8 minutes, 24 hours a day, for nine years over Laos.

A brief background of the site and battle |

Lima Site 85 was one of the most critical U.S. installations in the Secret War—its radar systems perched on Phou Pha Thi guided bombing missions deep into North Vietnam. Operated under deep cover by U.S. Air Force personnel and defended by Hmong and Thai allies, the site became a prime target for North Vietnamese forces. In March 1968, after days of buildup and delayed evacuation, the mountain was overrun by a a sapper unit in a brutal assault. Most of the American personnel were killed or went missing - while others were saved in a dramatic Air America helicopter rescue - making it the largest single ground loss of Air Force members during the Vietnam War and a stark reminder of the war’s hidden costs.

The story of Lima Site 85 is involved. As the Vietnam War expanded with the introduction of US ground troops to support the South Vietnamese government against the Viet Cong (National Liberation Army) insurgency in 1965, the North Vietnamese increased their supply and infiltration into South Vietnam via the Ho Chi Minh Trail.

The US military needed to stop that infiltration that went through Laos as well as Cambodia. With the cooperation of the Royal Lao government, supposedly a neutral country which was fighting an insurgency civil war with the North Vietnamese-supported Communist Pathet Lao forces, the CIA financed and armed the Lao tribal Hmong Clandestine Army. Along with numerous Lima Sites which usually consisted of an airfield or landing zone, the CIA supplied and advised the pro-Laotian government forces.

In order to more accurately guide American bombers on their missions in North Vietnam and along the Ho Chi Minh Trail, the CIA set up the radar and navigational base Lima Site 85 on the tallest mountain closest to North Vietnam - only 15 miles away - in 1966. It was situated in the heart of communist contested Laos and only 40 miles away from the Pathet Lao headquarters at Sam Nuea - later moved to the Vieng Xay cave complex.

In 1967 with the introduction of the all-weather AN/TSQ-81 radar bombing control system, Lima Site 85 guidance accuracy increased dramatically allowing bombing missions during inclement weather and particularly during overcast and and rainy monsoon season. The system also helped decrease the number of American aircraft shot down over North Vietnam.

Though supposedly secret, the operation was well known to the North Vietnamese and knowing its importance, the Peoples Army of North Vietnam (PAVN) set in motion an elaborate plan to neutralize the base. They started to build a road south from Dien Bien Phu (the site of the French colonial army defeat in 1954) while the Pathet Lao moved towards it from their base at Sam Nuea. As an estimated 3,000 North Vietnamese soldiers closed in, an elite commando platoon from the PAVN 41st Special Forces Battalion had trained for nine months in mountain assault warfare.

The outpost was guarded by about 1,000 Hmong Army soldiers and 300 CIA-paid Thai Border Patrol soldiers. It was supplied by Air America helicopters and planes who also provided surveillance to initially un-armed American civilian Air Force technicians. As the North Vietnamese closed in on the outpost, bombing missions were redirected in an attempt to stop their advance. The important Royal Lao Army base of Nam Bac north of LS 85 was overran in January 1968.

In a unique encounter on 12 January 1968, the Vietnam People's Air Force, in one of their few operations, attempted to blow up the site with an aerial attack involving several Soviet-made Antonov An-2 biplanes that were armed with rockets and hand dropped mortars. As they made their strafing runs and dropped their bombs one aircraft was damaged by ground fire and crashed. Meanwhile, CIA officers and US controllers were able to call in an Air America Huey that pursued the remaining Antonov into North Vietnam and with a CIA operative using an AK-47 was able to shoot down the plane.

As the situation became more precarious when North Vietnamese forces were able to get within artillery range and shell the position, US Ambassador to Laos William Sullivan who was also in charge of the CIA Secret War operation prepared for the evacuation of the Americans and their Hmong and Thai allies.

Meanwhile in South Vietnam, the Tet Offensive which had started on 30 January 1968 was still in progress with the seige of Khe Sanh continuing and other engagement throughout the south. Orders were given, possibly even from the White House according to some sources, to hold out at Lima Site 85 and keep the substantial enemies forces at bay for as long as possible.

With the likelihood of outpost being overrun as North Vietnamese and Pathet Lao forces closed in, Ambassador Sullivan finally ordered the evacuation of the site to begin at first light on 10 March 1968. In defiance of the Ambassador's orders not to arm the "civilians", Major Richard Secord, had earlier provided the 19 outpost personnel with M-16s and some grenades.

With regular North Vietnamese forces engaging the Hmong and Thai security forces protecting the outpost, the 33-man NVA Special Forces platoon divided into five cells climbed the cliffs -avoiding detection- and were in position to attack at 3am.

The resulting ambush of the attack left 11 Americans MIA or KIA and 42 Hmong and Thai soldiers dead.

As the battle between the NVA commandos and lightly armed US personnel raged, a CIA operative at the helicopter landing zone called in air support and evacuation helicopters and then rushed up to engage the attackers.

On a ledge below the cliff, CMSGT Etchberger held off sappers in a prolonged fight, eventually helping get surviving fellow airmen lifted onto an Air America helicopter hovering precariously over their position.

Etchberger was initially awarded the Air Force Cross, but in 2010 his award was upgrade to the Medal of Honor.

The Medal of Honor citation |

The President of the United States of America, authorized by Act of Congress, March 3, 1863, has awarded, in the name of The Congress, the Medal of Honor to Chief Master Sergeant Richard L. Etchberger, United States Air Force, for conspicuous gallantry and intrepidity at the risk of life above and beyond the call of duty.

Chief Master Sergeant Richard L. Etchberger distinguished himself by extraordinary heroism on March 11, 1968, in the country of Laos, while assigned a Ground Radar Superintendent, Detachment 1, 1043d Radar Evaluation Squadron. 

​On that day, Chief Etchberger and his team of technicians were manning a top-secret defensive position at Lima Site 85 when the base was overrun by an enemy ground force.  Receiving sustained and withering heavy artillery attacks directly upon his unit’s position, Chief Etchberger’s entire crew lay dead or severely wounded.  Despite having received little or no combat training, Chief Etchberger single-handedly held off the enemy with an M-16, while simultaneously directing air strikes into the area and calling for air rescue.  Because of his fierce defense and heroic and selfless actions, he was able to deny the enemy access to his position and save the lives of his remaining crew. With the arrival of the rescue aircraft, Chief Etchberger, without hesitation, repeatedly and deliberately risked his own life, exposing himself to heavy enemy fire in order to place three surviving wounded comrades into rescue slings hanging from the hovering helicopter waiting to airlift them to safety.  With his remaining crew safely aboard, Chief Etchberger finally climbed into an evacuation sling himself, only to be fatally wounded by enemy ground fire as he was being raised into the aircraft. 

​Chief Etchberger’s bravery and determination in the face of persistent enemy fire and overwhelming odds are in keeping with the highest standards of performance and traditions of military service.  Chief Etchberger’s gallantry, self-sacrifice, and profound concern for his fellow men at risk of his life, above and beyond the call of duty, reflect the highest credit upon himself and the United States Air Force. 

Of the 11 Americans killed, other than Chief Etchberger, only three other servicemen's remains have been found and identified. After visits by US Department of Defense Joint POW/MIA Accounting Agency in 2024, Sgt David S Price was the latest MIA to have had remains recovered.

Exploring the remote site with it's exposed steep drop offs and exposed terrain, it gives you a clear sense of just how vulnerable the defenders were. There’s not much left—some battle effects, rusted metal, and stark terrain—but being there gives you a sense of the battle in a way no written account can.

For more information on the Battle of Lima Site 85, you can visit the following sites: https://en.wikipedia.org/wiki/Battle_of_Lima_Site_85 and https://www.limasite85.com/

We headed down the mountain, stopping at the landing zone where we found the artillery gun that had been knocked out commission by the North Vietnamese.

On the way back, smoke from slash and burn agriculture obscured the mountains and strong winds brought short downpours of rain. We briefly stopped at a Buddha Cave shrine as dark clouds and an impending storm darkened the sky after an impactful and unforgettable day.

We ended the day with an excellent pizza at Pizza Aloha. We were the only diners at the one table outdoor eatery as a gentle rain fell and thunder rumbled in the distance.

Day Four | Pathet Lao and the Vieng Xay cave complex

We were up early and on the road to Vieng Xay, a natural karst and cavern geological formation, where the Communist insurgency army Pathet Lao had moved their headquarters to shelter against American bombing raids in 1964.

Initially the non-communist revolutionary movement was formed in 1945 and in 1950 Prince Souphanouvong of the Royal Lao family, who had lived in Vietnam and met Ho Chi Minh, became it's leader. The renamed Pathet Lao joined with the Viet Minh to fight against the French colonialist rulers in the First Indochina War. In 1953 the now communist revolutionary force was joined by Viet Minh insurgents and invaded Laos and established a base of operation in Vieng Xay with close collaboration with the Viet Minh.

In 1954 after a number of French colonial Army defeats in Vietnam by the Viet Minh, most notably at Dien Bien Phu, the Geneva Conference divided French Indochina into four countries, Democratic Republic of Vietnam and State of Vietnam, Cambodia and Laos. All foreign forces were to be withdrawn, but the North Vietnamese forces remained along the border regions of Laos and continued to coordinate the Pathet Lao Civil War in Laos.

In 1961 with the United States becoming increasingly involved with military and political support for the South Vietnamese government and fear of the spread of communism, the US backed the Kingdom of Laos. It started to supply weapons and training to the Royal Lao Army as well as the CIA recruited Hmong clandestine guerrilla army led by Major General Vang Pao.

We arrived at the Vieng Xay ticket office by 8:30am and needed to wait awhile until a guide could be found. You are only able to visit the cave complex site with a guide and there are only two times for tours. With audio tour headsets and following our guide Goa who led us to the sites on his vespa, we started a fascinating tour of the area. There are over 400 caverns and caves that were used by the Pathet Lao and with the local population the caves housed up to 20,000 people.
