The Battle of Phủ Tông Hoá took place near the village of Phủ Tông Hoá on Route Coloniale 3 bis (RC3 bis), north of Bắc Kạn. The garrison, comprised of 107 Legionnaires and colonial artillerymen, repelled a major night assault by Việt Minh forces of Regiment 141. The post remained in French hands after several hours of fighting and was relieved on 28 July. In Vietnam, the battle is still considered to be an important milestone as it was the first Việt Minh coordinated assault against a fortified French position. The lessons learned at Phủ Tông Hoá informed Việt Minh doctrine and training, and contributed to the major Viet Minh victory on Route Coloniale 4 in September-October 1950.

Background

Phủ Tông Hoá outpost

Following Operation LEA (a three-axis assault into the Việt Bắc sanctuary zone) in October 1947, the French maintained a chain of posts along RC4 and RC3 bis to secure the Chinese border region and the Cao Bằng–Bắc Kạn axis. Phủ Tông Hoá, overlooking the village of the same name, was garrisoned by the 2nd Company, I/3rd Foreign Infantry Regiment (3e REI - Régiment Étranger d’Infanterie), reinforced by gunners from the 69th African Artillery Regiment (69e RAA– Régiment d’Artillerie d’Afrique). The fort was constructed of earth-and-timber walls with four concrete blockhouses, numbered I, II, III, and IV; wire and bamboo obstacles; and defensive mine belts.

Company 124 breached the northern defences, and Company 122 breached the western defences. The battle then became a vicious close-quarter fight for the blockhouses and garrison buildings.

In early June 1948, French intelligence services noted increased Việt Minh activity along RC3 bis, and particularly in the vicinity of the Phủ Tông Hoá post. By late July, the intelligence indicated that a Việt Minh assault was imminent. On 23 July 1948, the French Northeast Frontier Zone Command ordered the Phủ Tông Hoá post to be prepared for evacuation, but the order was cancelled the following day.

For the Viet Minh, fortified posts like Phủ Tông Hoá represented a formidable challenge. French artillery, defensive minefields, barbed wire and abatis, and mutually supporting machine gun positions all had to be overcome for any assault to succeed.

The Viet Minh plan for the assault of Phủ Tông Hoá was to position their few artillery pieces on dominating terrain to fire over open sights at the French blockhouses. Under the cover of this fire, three companies of Battalion 11, Regiment 141, would infiltrate to their final assault positions to the northeast, west and southwest of the fortified post. The assault would be initiated by bugle signal.

At approximately 19:30 on 25 July 1948, Việt Minh artillery (including Japanese 75 mm mountain guns and a 37 mm gun) opened fire on the post from high ground to the north and west of the fort. Under the cover of the artillery barrage and a torrential rainstorm, the Việt Minh infantry companies infiltrated to within 50 metres of the post. Company 124 occupied a position near Blockhouse III in the northeast. Company 122 occupied a position close to the western perimeter. Company 120 infiltrated the village of Phủ Tông Hoá in preparation for an assault against the main gate. At about 21:00 hours, the Việt Minh assaulted the fort from multiple directions.

As planned, the infantry assault was initiated by bugle call. Việt Minh attackers rose from their final assault positions very close to the French perimeter, taking the Legionnaires by surprise. However, the Việt Minh assault still had to pass through the defensive minefields and obstacle belts, and the French machine guns cut down the leading waves.

The French garrison commander, Captain Hervé Cardinal, was mortally wounded in the opening bombardment. Lieutenant Charlotton assumed command, but he too was mortally wounded. Sous-Lieutenant Jacques Bévalot now assumed command.

The perimeter was breached at several points. Assault troops from Việt Minh Company 122 used bamboo ladders to breach the western perimeter and seized Blockhouse IV. Elements of Company 122 were able to enter the commander's house, but French machine gun fire inflicted many casualties, and the breach was effectively sealed.

On the northwestern corner of the post, Viet Minh Company 124 breached the French perimeter near Blockhouse III, but took many casualties and could not penetrate further.

Inside the post, Lieutenant Bévalot rallied the surviving Legionnaires and artillerymen and coordinated counterattacks to clear Viet Minh survivors from the perimeter. One by one, the Viet Minh occupied blockhouses and buildings were cleared.

The Việt Minh Battalion Commander, having achieved success at several points, attempted to reinforce the assault with his reserve Company 120, but was unable to make contact with them. Company 120 effectively took no part in the battle.

The heavy rain ceased around 22:30 hours, and the Legionnaires were able to re-establish the perimeter and eliminate any last pockets of Việt Minh resistance. By midnight, Lieutenant Bévalot was able to report: “The post is entirely in our hands.” Việt Minh bugle calls now sounded the withdrawal, and surviving elements of the Việt Minh assault force extricated themselves back through the minefields and obstacle belts.

Aftermath

Viet Minh memorial at Phủ Tông Hoá . Each marble plinth records the names the Viet Minh fallen during the Battle of Phủ Tông Hoá on 25 July 1948. 42 names are recorded.

On 26–27 July the depleted garrison restored communications and prepared for renewed attacks while French relief efforts were impeded by Việt Minh interdiction along RC3 bis. A relief column under Lieutenant-Colonel Jean Simon, commanding 3e REI, reached Phủ Tông Hoá on the evening of 28 July.

French losses are recorded as 24 killed and 33 wounded; Việt Minh casualties are uncertain, with memorial plaques at the Phủ Tông Hoá site recording 42 fallen, all from Battalion 11, Regiment 141. The engagement demonstrated the Việt Minh's evolving tactics for assaults on fortified posts and foreshadowed later operations on RC4.

General Vo Nguyen Giap, military commander of the Viet Minh, visited Battalion 11, Regiment 141, after the Battle of Phủ Tông Hoá to congratulate them on their performance during the assault. For the Việt Minh, the most important outcome of the battle was the lessons learned in coordinating artillery and infantry actions, and in breaching French fortifications.
