When Song Xiaofei took 3,000 new troops to "Hanoi" in Vietnam, it was almost winter, and the weather in northern Vietnam was quite warm, like Kunming in all seasons. However, because it belongs to the mountainous area, the deep mountains and old forests are the same as the mountainous areas of Guizhou, freezing rain at every turn, and the air is damp and cold. At that time, the 500 French troops led by Li Weiye had occupied the city of "Hanoi," and Liu Yongfu's 2,500 Black Flag troops were entrenched at the paper bridge outside the "Hanoi" city, and the two sides confronted each other.

That afternoon, Song Xiao flew to the command camp of the Black Flag Army, but did not see Liu Yongfu, and unexpectedly met Su Yu, the sister of twin sister Hua. Back then, Liu Yongfu was also a general of the Black Flag Army who opposed the Qing Dynasty, and Su Yun and Su Yu's father Su Tianfu were sworn brothers who exchanged greetings. After Su Tianfu and his family were captured by the Qing army, Liu Yongfu led people to risk their lives to rescue the young Su Yun and Su Yu, accepted them as righteous daughters, and taught them kung fu. In the twelfth year of Tongzhi, after Su Yun and Su Yu were let go by Song Xiaofei in Xiangcheng, they returned to Yunnan to find their master Liu Yongfu, and followed Liu Yongfu for the next seven or eight years.

At this time, Song Xiaofei was thin and tall, and he was also wearing the three-grade official uniform of the Qing Dynasty's five-clawed and nine-python, Su Yu, who was dressed as a man, didn't recognize him as the young man who saved the two sisters back then, and came to salute with a sad face.

Song Xiaofei was surprised and happy in her heart, and glanced at Su Yu, she was dressed in plain clothes at this time, with a green silk bun on her head, two curved willow eyebrows, a pair of phoenix eyes, her face was snow-white without powder, her lips were not painted with vermilion and were red, her height had also grown a little taller, her big eyes flashed and flashed, full of tears, she felt a little more mature than back then, and her chest was fuller than before.

Seeing Su Yu's sad face, Song Xiaofei asked why he didn't see Liu Yongfu, the deputy governor of Sanxuan. Su Yu said that her sister Su Yun secretly went to the Hanoi church two days ago, and was discovered by French soldiers and arrested.

When Song Xiaofei heard this, Liu Yongfu was really a man with affection and righteousness, but he brought about 20 Black Flag troops into the city to rescue him, and he didn't take the French guns and cannons too seriously. He counted the roster of the Black Flag Army, and found that the famous Black Flag Army in history was only 2,500 people, and most of the weapons were broadswords, spears, and 1,000 firearms.

Song Xiaofei asked for a topographic map of "Hanoi" and was looking at it, when suddenly he stumbled outside the tent and climbed into a bloody Black Flag Army sentry dog baby, and reported to Su Yu that Liu Yongfu had rescued Su Yun from the church in Hanoi and was running towards the paper bridge, about ten miles away, and there were chasing soldiers behind, French Navy Colonel Li Weiye was chasing them with a large group of men and horses, and General Liu asked the Black Flag Army that had been ambushed in the paper bridge to prepare for battle.

Su Yu still didn't have an opinion about fighting, Song Xiaofei asked the dog baby: "How many people did Li Weiye bring to chase him out?" ”

The dog baby replied, "About three or four hundred." ”

As soon as Song Xiaofei heard that there were three or four hundred French troops attacking, he realized that most of the French troops in Hanoi had been chased out, the situation was critical, and it would be dangerous if he did not fight Liu Yongfu and the Black Flag Army, so he hurried to the top of the mountain to inspect. Before returning to North Korea, he spent 30 taels of silver in the capital to buy a pair of military telescopes made by the Netherlands. From the binoculars, he saw that the French army led by Li Weiye was chasing Liu Yongfu and Su Yun, as well as more than a dozen Black Flag troops behind them, and from time to time the Black Flag Army was shot and killed, and Liu Yongfu had also been shot in the thigh, and Su Yun was supporting him to flee for his life.

Song Xiaofei found that the infantry of the French army was divided into three categories: flintlock pikemen, grenadiers, and riflemen. Moreover, the rest of the French army's weapons and baggage were also very advanced, the flintlock musketeers used firing machine guns, and there were several heavy cannons in the back of the French ranks. Song Xiaofei saw in "On War" that flintlock pikemen and grenadiers usually lined up in a relatively close formation to develop their firepower. The rifle men will form a skirmish line, which is used to shake the enemy's defensive line when attacking; When defending, it is used to disrupt the rhythm of the enemy's attack, which is very strong. And the rifle has a higher accuracy and a longer firing range. The cannon fire is even more ferocious, and a few cannons are estimated to be able to collapse the paper bridge.

Song Xiaofei thought to himself that the Krupp guns and Mauser guns purchased by Li Fengbao in Germany had not yet arrived, and with the firearms of the Huai Army and the Korean Army at that time, they could not fight hard with Li Weiye's French army, otherwise they would be prone to heavy casualties. can only occupy the right time and place to carry out ambushes. So, Song Xiaofei sent someone to tell Su Yu that the Black Flag Army ambushed near the paper bridge could only be defeated but not victorious, retreated from the paper bridge, and lured Li Weiye's French army into the valley.

Dressed in the uniform of a French naval colonel, Li Weiye rode a tall horse and chased Liu Yongfu and his Black Flag Army like prey. His blue eyes shone with the same haughty glow as a wolf. In his opinion, the defeat of the French army by the Black Flag Army nine years ago was completely due to the incompetence of Captain An Ye, and he even deliberately slowed down the French pursuers, just like he deliberately let Su Yun and Liu Yongfu go in the city, and let Liu Yongfu take the French army to the deep mountains and old forests to find the Black Flag Army for a decisive battle.

It was getting dark, the air in the mountains was cold, Li Weiye led more than 400 French soldiers on the muddy path of the Hanoi forest, the French military boots accompanying him were stained with yellow mud, and behind the team, the four most advanced cannons of the time were particularly dazzling. Li Weiye also knew that there might be an ambush by the Black Flag Army near the Paper Bridge, but he relied on the advantage of the French army's firepower and did not take the Black Flag Army's ambush in the slightest.

The French army arrived near the paper bridge, and the Black Flag Army ambushed there began to release cold arrows with a "whoosh", Li Weiye saw that the equipment of the Black Flag Army was still an ancient bow and arrow, which was simply an insult to himself, and immediately ordered the soldiers to line up in formation, and the echelon shot forward, and the Black Flag Army ambushed under the bamboo fence and grass fortress was shot, with countless casualties, Li Weiye also ordered the cannon to fire, and the Black Flag Army quickly broke and fled half-truthfully.

Seeing the fleeing Black Flag Army, Li Weiye laughed and said to Dai Xili, the adjutant beside him: "Xili, this group of pigs is still alive in the Stone Age, they can only play with big swords and spears, so vulnerable, no wonder the Chinese Emperor Yanjing was frightened by our French guns and cannons twenty years ago and fled to Rehe." If we don't attack Yanjing City directly, go to the Old Summer Palace and the Forbidden City to make another profit, with a lot of gold coins, there will be a lot of noble ladies waiting for us when we return to China in the future! Daisily did not expect the Black Flag Army to be so weak in combat effectiveness, and flattered Li Weiye: "It was the heroism of the colonel that scared the Chinese, and this time we took advantage of the victory to pursue and completely annihilate the Black Flag Army." ”

Li Weiye ordered the French army to continue to advance and chase and kill the Black Flag Army, along the way the Black Flag Army suffered heavy casualties, killing three or four hundred people, and the corpses were scattered all over the field. Ahead is a long, narrow valley lined with dense pine forests that are unusually quiet. At this time, a flash of lightning swept through the sky, and the sky was beautiful, and it began to rain freezing, and the raindrops fell on the French cannons, and the gunpowder soon became damp. In the rain, the heavy armament of these four cannons instead became a burden on the advance of the French army.

After a cup of tea, the French army gradually entered the encirclement of the Huai army. Su Yu, who was hiding behind the small hill, saw the French army, gritted his teeth with hatred, and was a little unable to hold back, and was about to do it when he took out the dart, Song Xiaofei grabbed her smooth little hand: "Don't worry, let this group of French people enter the ambush circle." ”

After all the French troops entered the ambush circle, Song Xiaofei jumped down the hill like a tiger, he was wearing a robe, a hat, and an M1847 revolver, like a ghost in the night, and suddenly appeared in front of Li Weiye's team. Li Weiye quickly took out his pistol, but unfortunately before he could hold it steadily, Su Yu hit him on the wrist with a dart. The pistol fell to the ground, Li Weiye screamed in pain, and then, a bullet flying from the muzzle of Song Xiaofei's revolver pierced his chest with a "bang", and his tall body slowly fell into the muddy water, with wide eyes open, dead and blind.

At the same time, a large number of Huai troops armed with muskets rushed out of the forest, and in the blink of an eye, bursts of gunfire rang out in the woods, and the French invaders became targets, mourning all over the field. Song Xiaofei also commanded the Korean army all the way back to the back of the French army, and the shouts and gunshots rolling in the forest, together with the thunder, made the French army frightened.

The rain became heavier and heavier, and the water on the ground was slowly stained red with the blood of the French invaders, and it went down the low terrain towards the small river beside the gorge. Song Xiaofei's face was also stained with blood, and in this battle, he deeply felt the cruelty of the monster of war: the more merciful he was to the enemy, the more dangerous he was.

In this battle, nearly 400 French troops were wiped out, Colonel Li Weiye was also killed, and four cannons and hundreds of rifles were captured by Song Xiaofei. The battle also thoroughly angered Prime Minister Fijury, a fanatical colonizer, who appointed the French general Gu Ba as commander of the expeditionary force, quickly sent 3,000 French troops to Vietnam, and also sent four warships to form the Beiqi Fleet, which drove violently towards Vietnam. For a time, the prime minister Yamen and the Qing court in China set off an uproar, arguing with the French about war or peace, chattering endlessly every day, which was more intense than on the battlefield.

Song Xiaofei also strongly felt that a bigger battle was about to start between China and France.
