Events leading to the Battle of Nà Sản[]

The Battle of Hòa Bình[]

  • In the Fall of 1950, French Expeditionary forces lost 7,000 men and over 3,000 tons of weapons after having been beaten by the Việt Minh in the Battle of Cao-Bac Lang. To avoid further losses, General Marcel Carpentier decided to withdraw all military forces from Hòa Bình, capital of the Muong region.
  • In November 1951, General De Lattre, Carpentier's replacement, launched an offensive operation against the Việt Minh in Hòa Bình to reclaim an area he saw as vital for France's future in Indochina. According to De Lattre, capturing Hòa Bình would cut the enemy's supply line between Thanh Hóa and Việt Bắc. Psychologically, reclaiming the province would gain support from the Mường, who had supported neither side, but were leaning more toward the Franco-Vietnamese force.
  • In November 1951, De Lattre mobilized 10 infantry and eight airborne battalions in this decisive operation. Giáp counterattacked with three regular divisions, two independent regiments, and regional support troops. The two sides fought hard for Hòa Bình. At the height of the operations, Giáp had 40 battalions fighting his enemies at different locations throughout the province. In January 1952, French forces were winning when De Lattre had to go back to France for cancer treatment and General Salan was appointed to take his place.
  • General Salan, who saw the province as an area that was hard to support and to defend, decided to withdraw his troops (Operation Amarante). On 22 February, French troops successfully withdrew from Hòa Bình and regrouped in Xuan Mai two days later.

T'ai region[]

  • Eight months after having successfully defended Hòa Binh, General Giáp attacked Nghĩa Lộ in the T'ai region which he failed to take a year earlier. General Giáp used four regular divisions (308th, 312th, 316th and artillery division 351st) to attack the province's southeast and the regional regiment 148th to guard the northwest side against reinforcements. In 10 days, Việt Minh forces not only took Nghĩa Lộ but also seized part of Sơn La and Lai Châu from French control.
  • To avoid further losses, General Salan launched Operation Lorraine to relieve the Việt Minh's pressure in the T'ai region and to serve as a diversion while Na San was being built. The operation, led by General de Linares, started on 9 November and lasted until 19 November.
  • While the operation was going on, General Salan tasked Colonel Jean Gilles of establishing an entrenched fire support base at Nà Sản to stop General Giáp's offensive.

Nà Sản[]

Nà Sản, conveniently located on provincial route 41 (RP 41), was a valley of 2 km x 1 km surrounded by 24 hills that could serve as natural defense positions. In early October 1952, there was a single outpost and a short airstrip, both guarded by a company under the command of a non-commissioned officer. General Salan used the Hanoi-based French Air Force Dakotas to transport troops and material there in order to complete a fortified outpost allowing a direct confrontation with the Việt Minh divisions.

The "hedgehog"[]

During the battle, Colonel Gilles used a new tactic, called "the hedgehog" (le hérisson), for the first time. The hedgehog defense consisted of an outpost surrounded by several armed positions (point d'appui or P.A.). The objective was to provoke an enemy frontal assault, rather than fighting off hit-and-run attacks or falling into ambushes. Nà Sản's hedgehog consisted of 30 P.A. with a complicated trench system, enforced with barbed wires. Its defense forces consisted of 11 battalions (15,000 men) and 6 artillery batteries.

This tactic earned the French a victory at the battle of Nà Sản. As a result, the hedgehog defense became standard practice, until the French defeat at Điện Biên Phủ.

The evacuation of a similar outpost at An Khê led to the disastrous Battle of Mang Yang Pass that ended the war in 1954. Though the Na San camp was successfully evacuated itself in August 1953.

The battle[]

Camp retranché de Na San nov-déc 1952
  • 23 November at 2000:

Vietminh forces from the 88/308 attacked twice at P.A. 8 and twice it was pushed back by the entrenched Franco-Vietnamese troops.

  • 24 to 30 November:

Every night, Vietminh forces attacked different points to test French defense. During the days, defending troops patrolled within their fire-support range for reconnaissance.

  • Late 30 November into 1 December:

At 8:00 PM, Vietminh forces from 9 battalions attacked P.A. 22 bis and 24, respectively located east and west of the entrenched headquarters. P.A. 22 bis, defended by a company of the 2nd Thai battalion (BT2) was overrun by the 115th battalion (165/312) after 9 hours of relentless attacks. Of the 225 men defending the P.A., only one squad was able to escape back to the airfield. P.A. 24 bravely resisted 3 hours of constant attacks by the 102/308 before surrendering.

  • 1 December:

Colonel Gilles, who wanted to take back the 2 points so close to Na San's headquarters, launched his attack at dawn. After a barrage of artillery fire, two companies of the 2nd Foreign Airborne Battalion stormed and took back 22 bis. After 7 hard-fought hours, the 3rd BPC took back P.A. 24.

  • Late 1 December into 2 December:

At 9:00 PM, General Giap's forces launched their all out offensive at Nà Sản. Wave after wave of soldiers relentlessly assaulted several P.A., especially 21 bis and 26; sometimes the attackers outnumbered the defenders fifteen to one. All night, Dakotas dropped flares over the battlefields to give support troops visibility to defend the positions. Defending forces continuously fired their cannons into Vietminh human waves while Privateers dropped bombs onto enemy positions around Nà Sản. The battles raged on until mid-morning when all attacks abruptly stopped, leaving behind an eerie silence.

Na San had achieved the unthinkable: halting Giap's seemingly unstoppable Vietminh forces.

Aftermath[]

  • On 4 December after nearly 2 weeks of trying to overrun Na San, General Giap withdrew his troops leaving behind 1,544 dead and 1,932 wounded prisoners (official numbers as reported by R. Vecken and P. Gras on the Flotille 9F website).
  • The defending Franco-Vietnamese forces lost close to 2 battalions.
  • Despite the victory, France was looking for a political solution to get out of Indochina and Na San was abandoned in August 1953. The tactician Colonel Gilles again outmaneuvered General Giap by evacuating the whole camp without a single loss. In "Ba sinh hương lửa", Doan Quoc Sy quoted a Vietminh officer with the forces surrounding Na San, "The enemy withdrew without our knowledge ... until there was only one battalion left ... the enemy was able to escape and save its entire forces because of our poor military intelligence".
