Sino-French War - French Intervention in Tonkin - Confrontation Between France and China - Son Tay and Bac Ninh

Son Tay and Bac Ninh

The French accepted that an attack on Liu Yongfu would probably result in an undeclared war with China, but calculated that a quick victory in Tonkin would force the Chinese to accept a fait accompli. Command of the Tonkin campaign was entrusted to Admiral Courbet, who attacked Son Tay in December 1883. The Son Tay Campaign was the fiercest campaign the French had yet fought in Tonkin. Although the Chinese and Vietnamese contingents at Son Tay played little part in the defence, Liu Yongfu's Black Flags fought ferociously to hold the city. On 14 December the French assaulted the outer defences of Son Tay at Phu Sa, but were thrown back with heavy casualties. Hoping to exploit Courbet's defeat, Liu Yongfu attacked the French lines the same night, but the Black Flag attack also failed disastrously. After resting his troops on 15 December, Courbet again assaulted the defences of Son Tay on the afternoon of 16 December. This time the attack was thoroughly prepared by artillery, and delivered only after the defenders had been worn down. At 5 p.m. a Foreign Legion battalion and a battalion of marine fusiliers captured the western gate of Son Tay and fought their way into the town. Liu Yongfu's garrison withdrew to the citadel, and evacuated Son Tay under cover of darkness several hours later. Courbet had achieved his objective, but at considerable cost. French casualties at Son Tay were 83 dead and 320 wounded. The fighting at Son Tay also took a terrible toll of the Black Flags, and in the opinion of some observers broke them once and for all as a serious fighting force. Liu Yongfu felt that he had been deliberately left to bear the brunt of the fighting by his Chinese and Vietnamese allies, and determined never again to expose his troops so openly.

In March 1884 the French renewed their offensive under the command of General Charles-Théodore Millot, who took over responsibility for the land campaign from Admiral Courbet after the fall of Son Tay. Reinforcements from France and the African colonies had now raised the strength of the Tonkin Expeditionary Corps to over 10,000 men, and Millot organised this force into two brigades. The 1st Brigade was commanded by General Louis Brière de l'Isle, who had earlier made his reputation as governor of Senegal, and the 2nd Brigade was commanded by the charismatic young Foreign Legion general François de Négrier, who had recently quelled a serious Arab rebellion in Algeria. The French target was Bac Ninh, garrisoned by a strong force of regular Chinese troops of the Guangxi Army. The Bac Ninh campaign was a walkover for the French. Morale in the Chinese army was low, and Liu Yongfu was careful to keep his experienced Black Flags out of danger. Millot bypassed Chinese defences to the southwest of Bac Ninh, and assaulted the city on 12 March from the southeast, with complete success. The Guangxi Army put up a feeble resistance, and the French took the city with ease, capturing large quantities of ammunition and a number of brand new Krupp cannon.
