Vương Thừa Vũ

As relations between the Democratic Republic of Vietnam (DRV) and France continued deteriorating in 1946, conflict grew increasingly likely, culminating in the Hai Phong incident. Anticipating further attacks by French forces, who had a 6,000-strong presence in Hanoi, the Viet Minh leadership appointed Vũ and approved his plan to defend the city.

Soldiers were posted at government buildings, industrial plants, and major thoroughfares of strategic significance. Arms and supplies were stashed in the city, and wall openings secretly made between houses to allow rapid, maze-like movement from street to street. Furniture was strewn across city streets as makeshift barricades in open view of French forces, and at night on December 19, 1946, some 2,000-10,000 Viet Minh engaged in their first instances of urban warfare, the heaviest fighting occurring in Hanoi's Old Quarter. The Viet Minh's failure to sabotage the Paul Doumer Bridge nor the military airbase at Gia Lam allowed the French to immediately rush in troops, supplies, and arms into Hanoi, achieving firepower superiority. From then on, the French slowly recaptured Hanoi from its poorly-armed defenders in a battle marred by civilian massacres and torture committed by both factions, and the Old Quarter was levelled to rubble by airstrikes and artillery.

By February, after heavy losses of several hundred dead, Vu withdrew his Capital Regiment, now reduced to 1,000 fighters, having delayed the French advance longer than expected. His defence allowed the DRV government to evacuate in an orderly manner, taking with them machinery, medical equipment, printing presses, and even the Voice of Vietnam transmitters into the countryside.[1]^{: 125–138}

He was reassigned to Military Zone 4 afterwards in Bình Trị Thiên, Central Vietnam, serving in subsequent turn under the other two Chinese-trained generals, Hùng and Sơn.[3]

On August 28, 1949, the Viet Minh formed its first regular, modern infantry battalion (later division) in Thai Nguyen province, the 308th Infantry Division. In light of the People's Liberation Army's rapid victories in China and the ongoing stalemate, the Vietnamese leaders realised they needed to professionalise and reorganise their military in order to wage war using modern weaponry that would arrive when the PLA reached the Vietnamese border. The unexpected PLA successes meant that the PAVN could now transition from guerrilla tactics to modern, conventional warfare in line with Mao's "General Counteroffensive" principles. They expanded their General Staff, recruiting more logistics, intelligence, and instruction personnel, and built a sophisticated officer corps trained to fight pitched, coordinated battles. They devised a new framework for infantry units, including large divisions numbering 10,000 to 15,000 men, and appointed the distinguished Vũ as commander.[1]^: 74–75

His division was soon involved in a series of major engagements. They fought against General Tassigny's forces in several abortive attempts to penetrate the Red River Delta, starting at Vĩnh Yên in January 1951, where initial success in half-destroying Group Mobile 3 was trounced by heavy French firepower during their counterattack, causing heavy losses. Firepower and the determined resistance of French troops again defeated the 308th and its sister divisions (the 312th and 316th) at Mạo Khê in March and the Day River in May–June, with human wave attacks failing to dislodge the French.[5]^: 113–14

After initially poor outcomes, his division achieved multiple victories in the following years: in 1952 they overran an outpost at Nghia Lo in just one hour,[5]^: 322 then fended off Operation Lorraine, ambushing retreating convoys to inflict high French losses.[5]^: 78–103 In 1953, they expanded Viet Minh presence into Laos, controlling territory in the Plain of Jars and encircling a French airbase to block the approach to Vientiane,[5]^: 126 then securing and expanding Route Provinciale 41, which later became the main Viet Minh supply route into Dien Bien Phu.[5]^: 265

Vũ led his men into battle at Điện Biên Phủ, where they played a leading role. His regiments stormed strongpoint Gabrielle on March 14–15, rapidly overrunning the command post and holding off French counterattacks until the latter abandoned the strongpoint late on the 15th.[5]^: 403–7 A couple of weeks later on March 28–31, they took part in the battle for five hills east of Dien Bien Phu, but failed to take Eliane 2 while Huguette 7 was recaptured by the defenders,[5]^: 470–81 after which Giap ordered all divisions to dig in around the remaining French forces.

In late April, they resumed the offensive with success, overrunning Huguette 1 to establish control over most of the airfield,[5]^: 526–33 and over the following weeks fought fierce battles to take Huguette 5 and Claudine 5 on May 6/7. When the French ceased resistance early on May 7, it was Vũ's 308th who captured the command bunker, and with it, General de Castries.[5]^: 601–17

Viet Minh troops on parade at Hanoi

After the Geneva Conference, his men returned to Hanoi on October 9, 1954, being the first Viet Minh division to re-enter the city.[6]^: 651 The local residents celebrated the soldiers' return, with a parade being held at Hang Dao street on the 10th while Vũ was photographed receiving flowers from students attending a local girls' school. He oversaw the DRV's flag-raising ceremony at the Flag Tower of Hanoi after his men had liberated the city, and established the Hanoi Military Commission at the Hanoi Opera House that same day.[7]
