Battle of Luang Namtha

The Battle of Luang Namtha, fought between January 1961 and May 1962, was an important engagement of 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 upon 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.

The slow motion battle began in far northwestern Laos, near its mutual boundaries with the People's Republic of China, Burma, and Vietnam. Although the Americans, who had replaced the French as benefactors of the Lao, both objected and cut off his funding, Phoumi insisted on the action. Between January 1961 and May 1962, 5,000 Royalist troops were fed into Luang Nam Tha. On the other hand, although the communists were outnumbered, they committed battle-hardened veterans of the People's Army of Vietnam to the battle.

On 6 May 1962, the Royalist defenses collapsed under an attack by four North Vietnamese battalions closing in from three directions. The panicked Lao troops fled down the Pak Beng Valley 160 km to the Mekong River, and beyond. Phoumi's military action having failed, he joined a coalition government to remain in power.

Nam Tha would remain in communist hands except for a few days in late December 1967, when a surprise raid by Royalist irregulars would occupy it temporarily.

Background
See also Laotian Civil War

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. Meanwhile, Vietnamese communists and Lao communists were active in Laos, sowing discontent against the government. The government itself was in turmoil, as various Lao soldiers 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.

On 14 December 1960, General Phoumi Nosavan won control of the Kingdom of Laos in the Battle of Vientiane. Although he was backed by American covert operations, he did not want to await a political solution to the political turmoil in Laos. In a move to assert control over Lao territory, he authorized military operations in northwestern Laos near the Chinese, Burmese, and Vietnamese borders. In so doing, he hoped to force a military solution upon the unsettled political situation in Laos.

The battle
In January 1961, the Royal Lao Army abandoned its occupation of Muang Xay, Laos. It withdrew into Luang Namtha, a village with about 1,800 inhabitants located 24 km from the Chinese border. The communist troops in the vicinity fired a few mortar rounds into the fringes of the town. Royalist reinforcements were flown into Luang Namtha over the next few days, including four 105mm howitzers and 12 75mm howitzers. T-6 Harvards from the Royal Lao Air Force were also operating from the unpaved airstrip there. Communist shelling beginning 1 February forced withdrawal of the T-6s to Luang Prabang. The American military attaché at that time deemed the topography of Luang Namtha to be too reminiscent of that around Dien Ben Phu to be defensible.

By May, the North Vietnamese communists had moved in a battalion of troops from their People's Army of Vietnam 316th Brigade. This invasion did not go unnoticed by the Royal Lao Government. They planned a two pronged response.

In September 1961, the Royal Lao Army formed an ad hoc regimental-size task force, Groupement Tactique 2 (Tactical Group 2) in Muong Houn, south of Muang Xay. The three Lao battalions were accompanied by U.S. Special Forces Field Training Team 40, which was stationed with them on a temporary duty training mission. Groupement Tactique 2's mission was to advance southeast up the Nam Beng Valley 82 km to Muang Xay.

The other Royalist prong emanated from Luang Nam Tha. In October, Bataillon Infanterie 2 (Infantry Battalion 2), accompanied by U.S. Field Training Team 2, made a three day eastward march to occupy Ban Namo. There they held up for a month, awaiting action from Groupement Tactique 2. On 2 December, they were reinforced by a fresh battalion, Bataillon Infanterie 1, as well as by Field Training Team 3.

GT 2, having undergone three months of training, kicked off its advance, but by 26 December had stalled halfway up the Pak Beng Valley. While the Green Berets tried to coax the column into further progress, the infantry battalion on the high ground screening the western flank fled after light contact by the communists. All but one company of the volunteer battalion comprising the main body of the expedition promptly followed suit. American advisers and the remaining meager Lao troops alike were left in a low-lying position that might easily be taken under plunging fire from the west.

At this juncture, Kuomintang General Li Teng led the Nationalist Chinese mercenary veterans who comprised Bataillon Speciale 111 (Special Battalion 111) down from their east flank hilltop. Bataillon Speciale 111 shielded the Americans for the next five days. On 31 December 1961, the Americans were extracted by helicopter and flown to the royal capitol, Luang Prabang. The Lao volunteers dispersed into the countryside. The Chinese mercenaries headed westward toward northern Thailand, departing the war.

On 21 January 1962, the other prong of the Royal Lao Army operation began to come apart. Bataillon Infanterie 2 (Infantry Battalion 2) ran from light probing fire from the Vietnamese. It was the turn of Bataillon Infanterie 1 (Infantry Battalion 1) the following day. The two American training teams were on their own. They were fortuitously rescued by an Air America Sikorsky H-34 despite their dead radio.

The failure of this pincer movement did not end the siege of Luang Nam Tha. General Phoumi Nosavan, who commanded the Royalist forces, was being pressured by his American supporters to await a political solution to the situation. Although all economic aid to Phoumi was cut off, including his troops' payroll, he spent the next three months reinforcing his garrison in the town, eventually stationing 5,000 troops there. His final deployment there, the elite Bataillon Parachutiste 11 (11th Paratroop Battalion), gave him a definite numeric advantage in manpower over his enemy's 2,500 troops. By late April, his patrols began probing enemy Pathet Lao and Neutralist forces.



On their side, on 28 March the communists mustered seven battalions detached from the PAVN 305th, 339th, and 316th Brigade, as well as Pathet Lao supernumeraries. They joined a North Vietnamese battalion already in Muang Sing. The reinforcements moved in on Luang Namtha from surrounding towns and were supplied by transport aircraft of the Soviet Air Force and the Vietnamese People's Air Force. On 5 May 1962, Communist troops ambushed one of the Royalist columns probing east of Luang Namtha. During their retreat, the soldiers of this column reported that they had been vanquished by Vietnamese Communist troops. At 0300 hours on 6 May, communist artillery fire fell upon the Royalist headquarters and its supporting artillery battery. A reported four battalions of communists simultaneously attacked from three directions. Panic spread throughout the Royalist positions. Royalist officers abandoned their posts and fled via helicopter or vehicle. The leaderless Royalist troops abandoned Luang Namtha and fled south down the Nam Beng Valley. Many of them did not stop until they reached the Mekong River, some 160 km south of Luang Namtha. Some of them transited the river and crossed the border into Thailand. The alarm spread by these deserters echoed back to the United States; President John F. Kennedy ordered 5,000 American troops to northern Thailand in response.

The American Special Forces training team that had been attached to the Royalists at Luang Namtha was hastily evacuated via helicopter. The Pathet Lao and Neutralists captured 2,000 Royalist troops still in town, along with abandoned munitions and arms. The debacle demonstrated the inability of Phoumi's Royal Lao Government to enforce its mandate, and led to a coalition government. In military terms, the Royal Lao Army had lost the service of more than a third of its maneuver battalions, including its elite paratroops.

A belated raid
In late December 1967, CIA case officer Tony Poe directed three battalions of Royalist irregulars in a raid upon Luang Namtha. The surprise move chased Pathet Lao defenders from the town. The Royalists held the town for two days while thousands of local civilians were evacuated, some by air and some by foot. As Pathet Lao forces regrouped east of town, the Royalists withdrew to the CIA base at Nam Yu, leaving Luang Namtha to the communists.
