The Great Vietnamese army could not attack for a long time, Zheng Gen did not dare to let the soldiers go to death, and the two armies confronted each other at the mouth of the Red River for five days.

In the camp of the Ming army, a figure walked into the big tent of the Chinese army, walked straight to Liu Qi, and whispered a few words in his ear.

"Alright, you go down, I see!" Liu Qi nodded after listening to his beard.

"Lord Liu, what's the situation?" Zheng Yun asked.

Liu Qi replied with a smile: "Good news! As long as it takes three more days, the Jiaozhi people on the opposite side will definitely withdraw their troops! ”

Nanyang Company has been operating quietly since Zheng Zhu refused to discuss the development of coal mines with Jiaozhi. Before the departure of the Ming army in Qiongzhou, the Ruan Dynasty in the south and the Mo Dynasty in the northwest had already agreed to send troops, and the Ming army dared to crusade against the Dayue Dynasty with less than 5,000 troops.

In the camp of the Da Viet Army, a messenger came to report: "Something is wrong!" Both the Mo family and the Ruan family have already sent troops! The Mo family is attacking Lang Son! The army of the Ruan family has already left the Great Wall and is advancing northward! ”

Vietnam also has the "Great Wall", which was the dividing line between the Nguyen and Hou Lê dynasties. Due to the strong strength of the Zheng lord of the Later Li Dynasty, he had an army of 150,000, 500 war elephants and more than 500 ships. The Ruan family only had 50,000 horses, 100 elephants and 100 warships, and their strength was obviously not comparable to that of Zheng Zhu, so the Ruan family built an eleven-kilometer-long, six-meter-high "Great Wall" in Quang Binh, with a Portuguese cannon every one zhang and a Portuguese heavy cannon every five zhang on the city wall. It was this "Great Wall" that enabled the Nguyen dynasty to resist the attacks of the Zheng lord in the north again and again.

After the envoys sent by the Nanyang Company to the Nguyen Dynasty, King Nguyen Phuc Binh was still hesitant to send troops. Ruan Youjin, the general of the Ruan Dynasty, refused to let go of this good opportunity, and said: "Lord Zheng is rebellious, not only above the emperor, but also detains the first assistant of the Heavenly Empire!" Now that the Celestial Empire has sent troops to fight against Lord Zheng, this is a good opportunity for our country, and we should send troops to cooperate with the Celestial Empire's army! ”

So the Ruan Dynasty sent 30,000 troops out of the "Great Wall" to the north to attack Zheng Zhu.

The Nguyen army opened the way with a hundred elephant soldiers. Along the way to the north, the army of Zheng Zhu, who had little defense, was rushed into the camp by the war elephants, trampled on all the way, and suffered heavy casualties, and the barracks were trampled by the thick elephant legs of the war elephants.

As the Nguyen army advanced northward, they bombarded the city walls with six 64-pounder mortar cannons imported from the Nanyang Company.

In fact, as early as the year before last, Pan Liu had contact with the Ruan Dynasty. Not long after the establishment of the Nanyang Company, Pan Liu went to the Nguyen kingdom, and the two sides had trade contacts. This time, after Nanyang Company failed to negotiate with Da Yue Guo to open a coal mine. In a fit of rage, Phan Liu sold six 64-pounder mortars to Nguyen's army.

Ruan Youjin was very satisfied with this stubby cannon, although the shell was filled with black medicine, but the explosive power of this cannonball should not be underestimated. After a few artillery bombardments, a fortified city was blasted open.

Although the mortar artillery had the weakness of having a short range, which was shorter than the Dutch cannon of the Viet Army at the head of the city, Nguyen's army used the night to build an earthen slope outside the city and placed the mortar behind the earthen slope that the Dutch heavy artillery could not bombard. When dawn came, the mortar began to bombard the city. However, the Dutch cannon of the Great Vietnamese Army at the head of the city had no choice but to watch the shells fall on their heads.

The Nguyen army advanced all the way north, and soon annihilated the Great Viet Army in Quang Binh, and Quang Binh fell into the hands of the Nguyen dynasty.

On the battlefield of the Northern Front. Moh's 10,000-strong army has entered Lang Son.

Compared with the Ruan clan in the south, the Mo clan in the north hates Zheng Zhu even more. The Mo Dynasty, which once occupied the entire northern part of Jiaozhi, was beaten by Zheng Zhu to only Gaoping, and Langshan, Quang Nam and other places were all lost.

The pain of losing the land made Mo Jingyu eager to recover Langshan as soon as possible. However, due to the lack of troops, the Mo Dynasty only had more than 10,000 horses and fifty war elephants. It's not Zheng Zhu's opponent at all.

Now that the Ming Dynasty sent troops to attack Lord Zheng, and heard that the Ruan clan in the south also sent troops to the Northern Expedition, Mo Jingyu naturally refused to let go of this good opportunity, and decisively ordered Mo Chao's 10,000 troops to go out to Langshan.

There are more than 2,000 regular Vietnamese troops in Lang Son City, plus the recruited Minzhuang, you can put together an army of seven or eight thousand people, with the defense of the city wall, you can resist the attack of 10,000 Mo's people, and it is not a problem to drag a large army to Zheng Zheng arrive. Who knew that the Mo army actually played the banner of "Qing Jun's side, punish the rebel thief, and help Li to destroy Zheng".

Seeing the banner of the Mo army, the morale of the temporarily recruited people fell to the lowest point. After all, in the minds of the Vietnamese people, the emperor is orthodox, and Lord Zheng is just a traitorous minister, and now they are fighting for traitorous ministers, which makes moral sense.

The banner of the Mo's army immediately collapsed the fighting spirit of the Dayue army and the people.

Next, Moh's army used four 32-pounder mortars imported from the Nanyang Company to bombard Lang Son City with flowering shells, which made the regular army of Da Viet taste the bitterness.

"Boom" the walls were blasted open.

The Mo's army shouted and rushed into Lang Son City. Lord Zheng's Da Yue army was defeated, slipped out from behind, and fled in the direction of Longsheng in embarrassment.

Lang Son City was originally the territory of the Mo family, and there are many remnants of the Mo dynasty here. Seeing that the army had regained its lost territory, the people of Jiaozhi, who were loyal to the Mo Dynasty, sang and danced to welcome the Mo army into the city. And seeing the banner of "Fu Li to destroy Zheng" played by the Mo army, even the people of Jiaozhi, who were originally loyal to the Li Dynasty, welcomed the Mo army into the city.

When Zheng Zheng learned that the armies of the Mo and Ruan clans were attacking from the north and south, he immediately sent an envoy to Zheng Gen and asked him to collect his troops and withdraw to Tokyo.

Zheng Gen received the order to withdraw the army, did not dare to slack off, and immediately pulled out the camp and retreated to Tokyo with the three-bowl army.

When he returned to the palace and saw Zheng Zheng, Zheng Gen bowed to the ground and bowed: "Father, the child is incompetent, and he lost a general as soon as he went into battle." After eight days of attack, they returned in vain. If you give the child another seven or eight days, you will definitely be able to break the false thief! ”

"The Mo thief in the north and the Ruan thief in the south took advantage of this opportunity to send troops! It's so hateful! Zheng Zheng said hatefully.

"Father, it's all the ghosts of the puppet thieves! Otherwise, how could Ruan and Mo send troops at the same time? The hypocrisy came to ask for someone. Father, according to the children, we have released their first assistant and 30,000 horses, and they will definitely withdraw their army! Zheng Gen made a suggestion.

Zheng Zheng said angrily: "I am a dignified Dayue Kingdom, how can I be bullied by the hypocrisy who has become a thief? The thief is attacked from three sides, it seems to be powerful, but in fact it is weak! There are only a few thousand people in the pseudo-Ming, and it is still a company escort team; Mohs up to 10,000 horses; The Nguyen clan can send 30,000 or 40,000 troops, which is already a lot! The total number of thieves in the three roads is only 50,000! We have an elite army of 130,000 in Da Viet Nam, if we admit defeat here, won't we be bullied so much that we can't raise our heads in the future? ”

Zheng Zheng first mobilized urgently. 60,000 Minzhuang and reserve troops were recruited, so that the number of troops in Dayue rose to 200,000 horses, and then troops were dispatched to deal with the enemy army attacking from three routes, and 30,000 troops were dispatched to deal with the Mo's army on the north route; 90,000 horses were dispatched to deal with the strongest Ruan army on the south road, and 50,000 horses were dispatched to deal with the Ming army on the middle road. The remaining troops were placed in Tokyo, firstly, to prevent the Ming army from attacking Tokyo in a roundabout way, and secondly, to guard against the Li army's own army of the Houli Imperial Court.

When Zheng Zheng dispatched troops, Zheng Yun was not idle, she sent envoys to borrow troops everywhere before leaving Qiongzhou.

At this time, the envoys sent by Zheng Yun went to Taiwan and Zhoushan respectively. For the sake of the niece's face, it is to rescue the first assistant of the Ming Dynasty. Zheng Chenggong promised to borrow 6,000 soldiers, led by Liu Guoxuan. Zhang Huangyan also agreed to come down, borrowed 3,000 soldiers, and Luo Zimu led the troops.

Taking advantage of the fact that the main force of the Great Yue Kingdom had not yet arrived, Liu Qi led the Qiongzhou army to the west along the river and attacked Haiyang City.

With Liu Qi's order, the Ming army launched a fierce attack on Haiyang City, which was only garrisoned by more than 1,000 regular troops of the Great Yue Kingdom and more than 2,000 people.

The four 64-pounder siege mortars burst out with astonishing power, and after three rounds of test firing with solid shells, the muzzle angle and the charge of gunpowder were adjusted. After that, the new flowering shells filled with Dana explosives began to be fired.

The walls of the city could not withstand the bombardment of such shells at all, and after four rounds of shelling, the walls were blown open by a breach.

The Ming army rushed forward and threw the national surname bottle at the Da Yue army in the city. Rockets were fired, and the hand-to-hand soldiers rushed into the city and fought fierce street battles with the Viet Viet army, defeating the Viet Cong. Captured Hai Duong City.

After Liu Qi captured Haiyang City, the Annan interpreter who followed him in the army told the people: "Lord Zheng is Cao Cao of your Dayue Kingdom!" The Zheng family went against the grain and held hostage the descendants of the Li family, the hero of Dayue. We, the Ming Dynasty, as the superior kingdom of the Celestial Empire, will not sit idly by! We are here to maintain orthodoxy, expel the Zheng family, and support the Li family! We have no intention of occupying your Da Yue Kingdom, and after expelling the Zheng clan, we will withdraw our troops immediately! ”

At that time, the officials of the Dayue Kingdom also studied the Ming Dynasty, all of them were scholars from the imperial examination, and they attached great importance to the etiquette of the monarch and the ministers, and heard that the army was here to maintain orthodoxy, and saw that the Ming army was not large in number and could not eat the Dayue Kingdom, so they all organized the people and turned their heads to support the Ming army.

An Nan interpreter in the Ming army said to the local officials of the Great Yue Kingdom: "The Zheng clan brazenly detained my Ming Shoufu and harmed my Ming officers and soldiers, and the crime is unforgivable!" We're here to pick us up! ”

Among the officials of the Great Yue Kingdom, there are also many descendants of the remnants of the Han people of the original Song Dynasty. Their ancestors came to Annam to avoid Meng Yuan and became Annamite people. Hearing that the Ming army had no intention of annexing Da Yue, these officials all supported the Ming army in rescuing Shoufu.

Fifteen days later, the 50,000-strong army of the Great Viet Kingdom arrived at the city of Hai Duong.

Compared with the strength of the two sides, Da Viet has 50,000 horses, 200 elephant soldiers, 3,000 cavalry, 8 Dutch-built warships, 56 domestically produced warships, and more than 300 Dutch-made cannons. The Ming army had less than 5,000 men, 10 sixth-class ships built by the British, no cavalry, and more than 400 cannons built and built by the British. Compared with infantry weapons, most of the Ming army was cold weapons, with only 500 bird guns and 500 archers. There were more than 5,000 musketeers in Viet Viet.

However, the Ming army also had twelve naval warships of the Nguyen Dynasty to help in the battle, and although there were not many ships in the navy of the Nguyen Dynasty, they were all large warships made by the Portuguese. The sailors of the Nguyen dynasty and the lord of Zheng had fought many times on the sea, and the sailors of the Nguyen dynasty won more and lost less. If it weren't for the safety of the Nguyen Dynasty's sailors, Lord Zheng's army would have bypassed the "Great Wall" and landed by sea to defeat the Nguyen Dynasty. Therefore, the fleet of the Nguyen Dynasty still has a certain strength.

The soldiers of the Great Yue Kingdom were stronger than the Burmese soldiers, and the strength of the Ming army of Qiongzhou led by Liu Qi was not as good as the army taken by Wang Xinyu, so this battle was not easy to fight.

Liu Qi ordered to hold out, and used the defense of the city wall and the cooperation of the warships on the water to repel the Great Vietnamese army again and again.

The Great Viet Army attacked for seven days in a row, but was defeated. On the river, the naval division of the Great Vietnamese Army was attacked by the combined forces of the Nanyang Navy and the Nguyen Thi Naval Division, and was defeated miserably, and the control of the river completely fell into the hands of the Ming army, which allowed the Ming army's supplies to enter the city of Hai Duong through the river without worrying about being besieged by the Great Vietnamese Army.

The fortress temporarily built by the Ming army on the wall of Haiyang made the Great Vietnamese army suffer enough, and left countless corpses under the city.

The Great Vietnamese army could not attack for a long time, and at this time, news also came from the northern and southern roads, saying that the Mo army and the Nguyen army also occupied the city and held it, and the Great Vietnamese army failed to attack. Looking at Haiyang City, which was built by the Ming army, Zheng Zheng was so anxious that he ordered the soldiers to attack the city at any cost.

At this time, Liu Qi, who was delaying time, finally waited for reinforcements to arrive.

"Oh no! An army of puppets appears on our left! There are 10,000 people! They're coming from the north! "A bloodied general rushed into the tent of the Central Army of the Great Viet Nam Army.

"What? Where did the thieves come from? Zheng Zheng was shocked.

"Go back to the king, observe the banner, it seems to be the puppet Min army and this army! The thieves are fierce, and the brothers are almost unstoppable! The general cried.

The sound of rolling thunderous artillery came, and the Ming army, which had discounted the banner of the Zheng Army and the banner of the Zhejiang Army, suddenly appeared on the left side of the Great Yue Army. After an eight-day voyage, the Zheng Jiajun and the Zhejiang army, under the guidance of the locals, entered the intricate lower reaches of the Red River. Immediately after the Ming army landed, it launched an attack on the flank of the Great Vietnamese Army.

The Zheng Jiajun and the Zhejiang army were newly arriving, and the morale of this coalition army was high, and as soon as they came up, they defeated the Dayue army and retreated. The Great Vietnamese Army attacked the city for several days, suffered setbacks for several days, and its morale was not high, and it was attacked suddenly, which caused the formation of the Great Vietnamese Army to be greatly disorganized.

In the Ming Zheng and Ming Zhang coalition armies, like two sharp arrows pierced into the heart of the Great Vietnamese Army, the Ming Army in the city took advantage of the situation to kill, and in a blink of an eye, it caused the collapse of the Great Vietnamese Army on the whole front.

"Defeated! Defeated! Our army is defeated! Run! "The Nguyen Dynasty's fine work mixed into the Great Vietnamese army, taking advantage of the chaos to shout loudly, and the fine work of shouting created even greater chaos for the Great Vietnamese army.

After Zheng Zheng left the elephant soldiers broken, he retreated in the direction of Longsheng with the main force.

The Min army and the Zhejiang army pursued the Dayue army, but were intercepted by elephant soldiers. Neither Liu Guoxuan nor Luo Zimu knew how to deal with the elephant soldiers, and as a result, the elephant soldiers counterattacked and lost many soldiers. At this time, Liu Qi's Qiongzhou army arrived. Liu Qi, who had participated in the battle against Burma, ordered the archers to shoot with rockets.

Several rows of rockets were fired over, and the war elephants of the Great Vietnamese Army turned around and ran, trampling on their own crowds, and more than 200 elephants stepped on a bloody path in the defeated Great Vietnamese Army, trampling to death countless Great Vietnamese soldiers. The Ming army pursued closely behind, killing the corpses of the Dayue army all over the field, and the blood flowed like a river.

The Great Vietnamese army was routed all the way, and the Ming army took advantage of the victory to pursue and reached the city of Tokyo. (To be continued.) )
