The Battle of Lak Sao, fought between November 1963 and January 1964, was a major engagement of the Laotian Civil War. In November 1963, General Phoumi Nosavan, who held the reins of military power in the Kingdom of Laos, launched a military offensive against North Vietnamese invaders that cut across the northern panhandle of the nation. Although unsupported in this proxy action by his backers in the U.S. Embassy, he went ahead with his plan to push northwards from Nhommarath, then veer eastwards to the Vietnamese border. Phoumi's Central Intelligence Agency (CIA) advisors warned him that the North Vietnamese would retaliate, but he disregarded them.

The Royal Lao Army (RLA) reluctantly carried out its mission until it met with stiff resistance. At that point, they tended to flee rather than fight. As fighting occurred throughout December 1963, two elite RLA units, the 11th and 55th Parachute Battalions, were rendered ineffective by the communists, and by a faulty parachute drop. A battalion of volunteers was also dispersed by the People's Army of Vietnam (PAVN). The Royal Lao Armed Forces (FAR) ended the operation in early 1964, having lost control of the Nakay Plateau to the communists. This, following the Battle of Luang Namtha, resulted in two disastrous defeats in just two years for the Royal Lao Government (RLG).

Background

The Kingdom of Laos emerged from the First Indochina War independent of the French, but in a state of chaos. Even as the French pulled out of Laos, the Americans took up their advisory role to the Royal Lao Government through such agencies as the Programs Evaluation Office (PEO). Meanwhile, North Vietnamese communists and Lao communists were active in Laos, sowing discontent against the government. The government itself was in turmoil, as various Laotian military leaders and politicians scrambled for positions of power. The American government became convinced that Laos could not be allowed to fall under communist control, lest other countries in Southeast Asia follow suit. [1]

On 14 December 1960, General Phoumi Nosavan won control of the Kingdom of Laos in the Battle of Vientiane. [2] Although he was backed by American covert operations, he did not want to await for a political solution to the political turmoil in Laos. In a move to assert control over Laotian territory, he authorized military operations in northwestern Laos near the Chinese, Burmese, and Vietnamese borders. In doing so, he hoped to force a military solution upon the unsettled political situation in Laos. [3] However, his northwestern forces spectacularly lost the Battle of Luang Namtha, and he was forced to join a coalition government. [3] In July 1962, the International Agreement on the Neutrality of Laos was signed, pledging that all foreign troops would exit Laos. The North Vietnamese government would not honor the treaty, however; they withdrew only a token contingent, leaving most of their invading troops inside Laos. [4] In its aftermath, Phoumi would make another attempt at asserting RLG control in a communist-controlled area of Laos, at Lak Sao. [5]

The battle

In November 1963, the Royal Lao Army and the Forces Armées Neutralistes or FAN (Neutralist Armed Forces) decided to cooperate on a joint operation to cut across the upper Laotian panhandle, thus severing the attacking forces of the People's Army of Vietnam (PAVN) in two. The planned starting point was Nhommarath, where a joint RLA/FAN task force was assembled. After advancing northward up Route 8 to Lak Sao, the RLA/FAN forces would turn northeast towards the Nape Pass, an entry point to the Democratic Republic of Vietnam. [5]

Although Phoumi and the RLG were heavily dependent on American military and logistical support, he did not pay heed to the American embassy's disapproval. The Americans judged the operation to be conducted too close to the Vietnamese border, and thus inviting retaliation from the PAVN. Nevertheless, the Laotians decided to go ahead anyway; General Sang Kittirath was placed in charge of the RLA/FAN task force. He committed the Neutralist Bataillon Infanterie 8 (Infantry Battalion 8), 5 Bataillon Parachutistes (5th Paratroop Battalion), and a Neutralist light tank company of PT-76s to the assault. By the end of November, the Royalist task force had occupied Lak Sao. At about the same time, Bataillon Regional 350 (Regional Battalion 350) occupied a westerly flanking position at Khamkeut. [5]

The thrust from Lak Sao moved toward Nape Pass as planned in early December, rolling down a road freshly improved by the North Vietnamese, and brushed off a blocking attempt by a company of Pathet Lao guerrillas. This was a prelude to an aggressive resistance that began on 15 December, as the North Vietnamese committed a minimum of three battalions to confront the Laotian thrust. While sending one column down Route 8 to hit the Laotian task-force head-on, the North Vietnamese also circled around southwards through the Mu Gia Pass to strike towards Nhommarat. On 16 December, the RLA rushed the paratroopers of 11 Bataillon Parachutistes (11th Paratroop Battalion) aboard Royal Lao Air Force C-47 transports and dropped them into Khamkheut. By 19 December, the sky soldiers had worked their way over to Lak Sao and begun pushing up Route 8. At a one-lane steel bridge, the paratroopers were bloodied by PAVN forces and retreated. They passed back through friendly forces still holding at Nak Sao, and returned to their Khamkeut drop zone. When Khamkeut came under mortar fire from the PAVN pursuers, 11 BP evaded an additional 6 kilometres (3.7 mi) west to the Nam Theun riverbank. [5]

The 55 Bataillon Parachutistes (55th Paratroop Battalion) was sent to the rescue. Its first attempt at a combat drop at Ban saw half of the battalion being blown off course over a ridge adjacent to the drop zone. After a second drop the following morning, the two paratroop battalions bypassed Khamkeut to relieve the garrison still holding their ground at Lak Sao. A confused withdrawal down Route 8 followed. Another reinforcing battalion, Bataillon Volontaires 34 (Volunteer Battalion 34) was also inserted into Khamkeut. [5]

In the early days of January 1964, the Pathet Lao guerrillas and PAVN soldiers chased BV 34 from the field. BI 8, 5 BP, and the tank company took to the woods; they eventually regrouped at Thakhek. The two paratroop battalions, 55 BP and 11 BP, managed to coalesce at Phon Tiou, some 60 kilometres (37 mi) northwest. By the end of the month, the Nakay Plateau area was now in communist hands. [5]

Consequences

The combat performance of the RLA seemed as poor as it was at the disastrous Battle of Luang Namtha the previous year. This was the second military defeat suffered by the Laotian general running Laos, Phoumi Nosavan. As a result of combat losses, BP 11 was shipped under Program 007 to be retrained by the Royal Thai Army at Lopburi, Thailand. [5] The Battle of Lak Sao also stripped the Royal Lao Army of a general reserve force. [6]

The Laotian Civil War was waged between the Communist Pathet Lao and the Royal Lao Government from 23 May 1959 to 2 December 1975. The Kingdom of Laos was a covert theater during the Vietnam War with both sides receiving heavy external support in a proxy war between the global Cold War superpowers. The fighting also involved the North Vietnamese, South Vietnamese, American and Thai armies, both directly and through irregular proxies. The war is known as the Secret War among the American CIA Special Activities Center, and Hmong and Mien veterans of the conflict.

The Programs Evaluation Office was a covert paramilitary mission to the Kingdom of Laos, established on 13 December 1955 by the United States Department of Defense. The 23 July 1962 International Agreement on the Neutrality of Laos would cause it to be shut down in September 1962. It would be succeeded by the Requirements Office.

The Battle of Nam Bac was one of the major engagements of the Laotian Civil War. Despite misgivings about their potential performance the Royal Lao Army moved in to occupy the Nam Bac Valley in August 1966; the position would block a traditional Vietnamese invasion route that led to the Lao royal capitol, Luang Prabang.

The Battle of Luang Namtha, fought between January 1962 and May 1963, was a series of clashes in the Laotian Civil War. It came about as a result of the turmoil following Laotian independence as a result of the First Indochina War with France. The Kingdom of Laos had foreign soldiers on its soil, and a political struggle in progress concerning those outside troops. Following a coup and counter-coup that left General Phoumi Nosavan in charge, the general decided on military action to settle the political issue of interlopers in Laos.

Operation Triangle was a military operation of the Laotian Civil War staged from 19—29 July 1964. Although planned by the General Staff of the Royal Lao Army, it was subject to American approval because the RLA depended on the Americans for finances, supplies, and munitions. Operation Triangle was an ambitious undertaking dependent on martial skills unfamiliar to the Lao. It not only called for coordination of infantry, artillery, and tactical air strikes among forces of three different nationalities; as a covert operation, it also had to have plausible deniability.

The Battle of Vientiane was the decisive action of the 1960 Laotian coups. Fought between 13 and 16 December 1960, the battle ended with General Phoumi Nosavan winning control of the Kingdom of Laos with the aid of the Royal Thai Government and the U.S. Central Intelligence Agency. Vientiane was left devastated by the fighting, with about 600 civilians dead, about the same number of homes destroyed, and 7,000 left homeless. The losing Forces Armées Neutralistes under Captain Kong Le retreated onto the strategic Plain of Jars, to begin an uneasy coexistence with the Pathet Lao and the invading People's Army of Vietnam.

The 1960 Laotian coups brought about a pivotal change of government in the Kingdom of Laos. General Phoumi Nosavan established himself as the strongman running Laos in a bloodless coup on 25 December 1959. He would be himself overthrown on 10 August 1960 by the young paratrooper captain who had backed him in the 1959 coup. When Captain Kong Le impressed the American officials underwriting Laos as a potential communist, they backed Phoumi's return to power in November and December 1960. In turn, the Soviets backed Kong Le as their proxy in this Cold War standoff. After the Battle of Vientiane ended in his defeat, Kong Le withdrew northward to the strategic Plain of Jars on 16 December 1960.

Forces Armées Neutralistes was an armed political movement of the Laotian Civil War.

The Patriotic Neutralists were an armed political movement of the Laotian Civil War. Founded in April 1963 by a schism within the Forces Armee Neutraliste (FAN) when the latter favored alliance with the Royal Lao Army, the Patriotic Neutralists allied themselves with the opposing Communist forces in the war. The most notable military action that involved them was a devastating air raid on 13 October 1969 that killed all its officers except commanding officer Colonel Deuane Sunnalath. Although it retained a nominally separate identity from the Pathet Lao, Patriotic Neutralist leaders Deuane Sunnalath and Khamouane Boupha would succeed to ministerial posts in the communist-dominated Provisional Government of National Union on 9 April 1974.

The 1964 Laotian coups were two attempted coup d'etats against the Royal Lao Government. The 18 April 1964 coup was notable for being committed by the policemen of the Directorate of National Coordination. Although successful, it was overturned five days later by U.S. Ambassador Leonard Unger. In its wake, Neutralist Prime Minister Souvanna Phouma forged a fragile coalition with the Pathet Lao communists. On 4 August 1964, Defense Minister Phoumi Nosavan attempted to take over Vientiane with a training battalion. This coup was quickly crushed by the local Royal Lao Army troops, as the police sat out the conflict.

General Sang Kittirath was a prominent military leader during the Laotian Civil War in the Kingdom of Laos. Between January 1955 and January 1965, he was successively the commander of Military Region 2 and head of the Ground Forces Command. His performance as commander of the losing side at the Battle of Lak Sao in early 1964, plus the loss of support from its political patron Major-General Phoumi Nosavan, led to Sang's resignation from command.

Major General Sourith Don Sasorith was a Royal Lao Government commanding officer during the Laotian Civil War. Appointed to command the Royal Lao Air Force on two occasions, he was also entrusted two other times with command of a Military Region. At the war's end in 1975, Sourith Don Sasorith was condemned to a communist re-education camp.

Kou Kiet was a major Laotian Civil War victory for the anti-communist troops of the Kingdom of Laos. Patterned after prior Operation Raindance, it depended upon extensive air strikes blasting communist units and clearing them from the path of the Royalist offensive. Powered by 150 daylight and 50 night sorties daily, with 50 to 80 day strikes directed by Raven Forward Air Controllers, Kou Kiet ran from 6 August to 30 September 1969. It was successful beyond expectations. After the Royal Lao Government troops achieved their objectives, General Vang Pao insisted on pushing forward while they had the initiative. As a result, the Royalists regained control of the entire Plain of Jars while also capturing a huge stock of munitions from the communist forces. Their triumph came at a huge cost. Even though the Royalists were successful, by battle's end their forces were exhausted and the pool of potential recruits were limited, while the Vietnamese could easily replace their personnel losses.

<span class="mw-page-title-main">Royal Lao Army Airborne</span> Military unit

The Royal Lao Army Airborne was composed of the élite paratrooper battalions of the Royal Lao Army (RLA), the land component of the Royal Lao Armed Forces, which operated during the First Indochina War and the Laotian Civil War from 1948 to 1975.

Operation Honorable Dragon was an offensive of the Second Indochina War. The Central Intelligence Agency, which equipped and trained the needed troops, aimed at disruption of the North Vietnamese communist supply line, the Ho Chi Minh Trail. Launched by six battalions of Royal Lao Army military irregulars on 31 August 1970, the operation achieved only limited success. Although the planned objective was captured on 25 September, the offensive was plagued by desertions and combat refusals, including a battalion that ran from "ghosts". After the conquest of Pakse Site 26, troops of the People's Army of Vietnam (PAVN) harassed the Lao occupiers through mid-December 1970.

Operation Phiboonpol was a "short but very intense engagement" of the Laotian Civil War. Five Royal Lao Government battalions went on the offensive in Military Region 4 of the Kingdom of Laos to try to regain the Boloven Plateau, which overlooked the vital Ho Chi Minh Trail lying to its east. Stopped in its tracks by the People's Army of Vietnam, with its first use of tanks in southern Laos, the Royalists held firm while close air support inflicted heavy casualties on North Vietnamese attackers. A Thai mercenary company sent as a Royalist relief force was ambushed and wiped out. For weeks after the battle, vultures feasted on unburied corpses.

Operation Xieng Dong was a successful defensive strike by the Royal Lao Army (RLA) against an invasion by the People's Army of Vietnam (PAVN). In early February 1971, PAVN forces swept RLA defenders from a line of hilltop positions guarding the royal capital of Luang Prabang. The city's perceived invulnerability to attack was shattered. King Sisavang Vatthana refused to leave his capital. Other Military Regions of Laos hastily forwarded to Luang Prabang's Military Region 1 any troops that could be spared from the rest of the Laotian Civil War. On 7 April, the resulting patchwork force of RLA battalions, Forces Armee Neutraliste half regiment, and Central Intelligence Agency-backed Special Guerrilla Units managed a three-pronged offensive supported by tactical aviation that surrounded and defeated the invading PAVN 335th Independent Regiment, which had gotten within eight kilometers of Luang Prabang. By 5 June 1971, the 335th was in full retreat.

Operation Maharat was a military offensive of the Royal Lao Government aimed at Communist insurrectionists. At stake was the sole road junction in northern Laos well in the rear of Royalist troops fighting in Campaign Z. On 30 December 1971, the garrison of a Royal Lao Army artillery battery and two Forces Armées Neutralistes battalions was besieged by an attacking force of Pathet Lao and Patriotic Neutralists. On 21 January 1972, the Royalists were reinforced by 11th Brigade, then overrun. The Communists spread north and south along Route 13 over a 110 km (68 mi) stretch. A Royalist counter-attack on 16 March 1972 would find both Route 13 and the intersection vacated.
