On the evening of 27 February, the remaining troops annihilated a black army that intended to advance in the direction of Xialong, capturing more than 80 black soldiers.

At noon on 28 February, more than 500 French and African colonial soldiers, including the blacks captured in the suburbs of Ha Long, were sentenced to death for war crimes after trial, and were immediately executed.

On March 1, the headquarters of the Nanyang Army dispatched superior forces to surround the city of Hanoi, and at the same time, in the name of the governors of Quang Ninh and Lang Son provinces, Mai Dong Xing wrote to the Annam government, suggesting that taking advantage of the crushing defeat of the French colonial army and the main force being besieged by the Nanyang Army in several isolated strongholds such as Hanoi and Haiphong, the main force in the northern region should be summoned to recover the land occupied by the French and cut off its tentacles of aggression extending to the northern part of Annam.

On March 5, the Hue Imperial Court issued a commendation document appointing Mai Dong Xing as the envoy of Zheng Er Pin Xuanfu, giving him a loyal and brave man, a reward of 15,000 taels of silver, and was also in charge of the defense of Quang Ninh, Lang Son, Bac Giang, and Bac Ninh. …………

Officers at and above the school level of the Nanyang Legion received promotions and silver rewards from the Annan government, but the Annan government took Mei Dongxing's suggestion as a big deal and delayed the reply of the discussion.

Over time, the effects of the war in Annam quickly spread to other parts of the world.

On the mainland, when they first heard the news that Li Weiye had led the French army to break through Hanoi, some of the attendants of the Hanlin Academy gave a lecture and planned to ask for a special dispatch of intellectuals to the three provinces of Guangdong, Guangxi, and Yunnan

Wehrmacht.

The Manchu government took into account the opinions of its ministers, and on February 28 issued an edict to the ministers along the border and coast, proposing that "it is important to protect the vassal states and hold the borders in our country." He also sent Li Hongzhang, who had returned to his hometown, to supervise the military affairs of Guangdong, Guangxi, and Yunnan provinces, because "this matter must be manipulated urgently."

In response to the opportunity, it is urgent to have prestige, and through the ministers of the incident to go to the preparations, it is possible to boost the prestige of the army and take into account the overall situation, and the advance and end of the defense forces of the three provinces must also be inherited."

In order to prevent Annam from being invaded and occupied by France, the Qing government was forced to make some bluff deployments and put on a tough attitude towards France.

However, in the face of the Manchu government's urgent orders, Li Hongzhang, who was in charge, played one after another to make the above decisions against the Qing government

Differing opinions. On 3 March, Li Hongzhang played "Secret Presentation of Vietnam's Border Matters," pointing out that Vietnam's current woes stem from the fact that Vietnam privately signed the 1874 Treaty with France, thus becoming a French protectorate, and virtually severing the traditional suzerain-vassal relationship that had existed with China for a long time. Therefore, China's desire to "protect its vassals" is inappropriate and inappropriate, and it advocates that China sit idly by and let Vietnam take its own place.

On March 5, he sent a letter to Prime Minister Yamen, reiterating the above proposition: Vietnam is "self-defeating and has no way to save itself." Accordingly, Li Hongzhang advocated that China abandon the policy of "protecting its vassals." Li Hongzhang was in favor of the decision to "stick to the border," but he believed that the geographical environment of Beiqi was complicated, "the roads were rugged, the water was poisonous and the wind was vicious, and the miasma of smoke was incomprehensible all year round." In addition, the remnants of the Taiping army were entrenched in the north and led the Chinese army to resist the French there, so the French army would not be so easy to annex Beiqi and disturb the border between Yunnan and Guangxi. Therefore, as long as the original deployment was carried out and the troops of Yunnan and Guizhou provinces were dispatched to deter the border, he also emphasized that according to the military strength and state financial situation of the Manchu government at that time, the Manchus should not start a war with France in order to help Vietnam.

"The coastal defense soldiers in the provinces are scarce, and the sailors have not been trained, so they cannot talk about war with the European powers, and they want to be in the light of the candlelight. It is fortunate that the balance is in hand, do not feel floating, provoke trouble, and mislead the overall situation. ”

On March 6, the Qing government adopted Li Hongzhang's suggestion, canceled his appointment to supervise the military of the three provinces, and ordered him to return to Beiyang as the acting minister, which meant that the Qing government had essentially retreated from the position of "helping Vietnam to resist the law and protecting its vassals."

On March 9, after learning the news that the Nanyang Army had completely annihilated the French colonial army in the north of Annam and surrounded the French white army,

The Manchu government was unusual,

On the one hand, because he was worried that the actions of the Nanyang Army would anger the French and cause the French government to be angry and send a large army to invade the mainland, he ordered Zhang Zhaodong, Liu Yuzhang and other officials in the southern coastal areas to strengthen coastal defense construction and prevent French warships from attacking.

On the other hand, the Annam government was reprimanded and the remnants of the Taiping army must not be allowed to provoke the French in the Kitasaka area, otherwise the Manchu court would no longer endorse Annam's safe status.

Unlike the Manchu government, which was reluctant to retreat, when news of the defeat in Annam reached the mainland, the French parliament unanimously approved a proposal to send reinforcements to relieve the besieged French army.

The Franco-Prussian War that took place in 1871 made the French lose face in Europe, and in order to save their national image, the French were like a gambler who lost red, ignoring the explanation of the Han diplomats who came to negotiate, and replied viciously, "The current situation is not 1871, the Han government must immediately withdraw your troops in the northern region of Annam, and stop the shameful sneak attacks and hostilities against the French army,............

On March 12, 1881, French Foreign Minister Shameraku instructed diplomats who were negotiating with the Han in South America: "The combat effectiveness of the Han army has exceeded our expectations, and the information we have received about the low combat effectiveness of the Han army in the Annam region is completely inconsistent with reality, and you should use various channels to obtain information on the real combat effectiveness of the Han army as soon as possible, so as to provide reference for the central government to formulate policies toward the Han state."

In order to welcome the arrogance of the French parliament in despising the Han state and rejoicing in the success, the French diplomat in South America replied: "The so-called combat strength of the Han army is ten

It is an exaggeration to say that the combat effectiveness of their native regular army is at most equal to that of the second-rate colonial army of France.

Moreover, the Han army troops are mainly concentrated on the mainland, the number of troops stationed in Annam is limited, and the supply depends on ocean transportation, and does not have the ability to fight for a long time. “

The report of the official of the French embassy abroad vigorously belittled the military strength of the Han state, saying: "The difference in strength between the two countries in land and sea is strangely exaggerated by my predecessor. If we take strong action in Annam, we will surely see the Chinese bandits retreat before us. If we decide to do a naval diversion, we will be able to inflict the most serious damage on the Chinese army. ”
