In mid-May, Nangong Yongjie was ordered to lead 30 steamships to the mouth of the Red River, accompanied by a 3,000 special combat team led by several special operations elites, including Pang Wanchun, Qiu Qionghu, Xie Zhen, Xie Bao, and Dai Zong.

At this time, the information from Zhou Dong in the front not only came, but the front-line troops attacking Wrestling City were all the way to the ground, and more than 20 cities and towns along the coast were about to be directed at the capital of Annan.

It's just that although the towns along the way have to keep people stationed, the troops may be somewhat insufficient. So, Zhao Chongyang sent Xue Yong to the port by boat to deliver a message, and asked Fang Tianjie to transport another 5,000 marines to the mouth of the Red River to support. He also ordered the recruitment of 1,000 recruits in each of the two emigrants and their training.

……

Moreover, the current king of Annam, Li Liangcai, is as ambitious as his ancestors and fathers, and is bent on expanding to the north and expanding his territory to the north of Lingnan. Therefore, after he ascended the throne, he used all his strength and continued to expand the army.

At the same time, he sent spies to infiltrate Dali City, instigating the princes to kill each other for the throne, so that Dali was in civil strife and had no time to take care of himself.

When the time was ripe, Li Liangcai sent his younger brother Prince Li Liangwu with hundreds of thousands of troops to take the opportunity to attack Dali.

Li Liang's military troops were divided into three routes, marching hand in hand, although they also suffered from the desperate resistance of the Dali State, the disparity in strength between the two scoundrels was too great, and the Dali State enjoyed peace for a long time, the combat strength of the officers and soldiers was too poor, and the generals of the army fought separately, and they were not the opponents of the Annam people at all.

When Zhao Chongyang's army was about to arrive at Annan Wrestling City, Li Liangwu's army was not far from Dali City, the capital of Dali State.

At the end of May, Li Liangcai, the king of Annam, received reports of a rout along the Red River, saying that an army of tens of thousands of people in the Great Song Dynasty had sailed north along the mouth of the Red River, and that many towns had been broken along the way.

At first, Li Liangcai did not pay attention to it, but every once in a while, the officers and soldiers who fled came back, saying that the army of the Song Dynasty was strong, and they were unstoppable all the way to the city. Seeing that it was getting closer and closer to the city of wrestling, there were more than a dozen cities, and they attacked the city of wrestling.

At this time, Li Liangcai finally panicked, and hurriedly flew the pigeon to pass the book, so that Li Liangwu could return to the army to save the driver, and the capital was in danger.

Although the Flying Pigeon Transmission is the fastest communication in the world, because the distance is more than 2,000 miles, although it is constantly passed from station to station along the way, it also took ten days to reach Li Liangwu's army.

After Li Liangwu received the notice to withdraw his troops and return for reinforcements, he was in a dilemma. After a few months, Dali recovered its vitality, and it was more difficult to destroy the country than to ascend to the sky.

If the troops are not returned, the total number of horses in the capital is less than 30,000, and it will inevitably be unable to withstand the fierce offensive of the Song army. Then when Dali destroyed the country, it was also the day when the city of wrestling was broken, and Annan also destroyed the country. At that time, the 350,000 troops who conquered the north will become the people who have lost the country, and without the country's strong logistical support, the hundreds of thousands of troops will become water without a source and a tree without roots, and it will not be long before it will collapse.

Li Liangwu and the strategists and generals in the army repeatedly calculated, and finally decided to take the measure of fighting on two fronts, sending 200,000 troops back to help, and the 15th army continued to attack Dali in the north, and after taking Dali City and nearby prefectures and counties, they held the passes and prefectures and counties on all sides, and then defeated the army of the Great Song Dynasty, and then waved their divisions to the north, eliminating the remnants of the local forces in Dali, collecting stragglers from all over the country, and controlling the prefectures and counties.

Because according to Li Liangwu's calculations, the army of the Song Dynasty would not exceed 100,000 at most, and the cities occupied would leave an average of 1,000 people per place, and 40,000 or 50,000 people would be needed, so the final siege of the capital would not exceed 50,000.

And that's not even counting battle damage and attrition. Because during the reign of Renzong, the Great Song Dynasty sent a large army to the south to conquer Annam, and although it was victorious in the end, the Song army died from natural disasters such as water and soil adaptation, dysentery, poisonous snakes, and miasma far more than the soldiers who died in the war.

Therefore, although the Song Dynasty won and lost in the end, it not only returned all the land of Annam, but also packed and sent all the passes that the Song Dynasty considered to be Jile, in exchange for the promise of the then king of Annam not to commit crimes in the north.

In order to be foolproof, Li Liangwu asked the general of the navy to lead 50,000 sailors down the Red River and strive to reach the city of Anjing within a month, and he led the 150,000 troops to withdraw by land, and two months later the capital would join the army.

However, Li Liangwu made a lot of calculations, but he didn't calculate that Zhao Chongyang's army was too strong. Although the entire army of land and water was less than 50,000, its combat strength far exceeded that of the army of Annam.

In particular, the special combat team led by Wu Song attacked the city and plundered the land as a common thing: before the siege, after a single artillery shot, the enemy army was already scared away, and they broke through the broken city wall without much effort, and the army quickly followed.

Wu Song handed over the city to the army and led the special combat team to pursue the remnants of the enemy with victory. If the enemy hides in the tropical jungle, they will take the tactic taught by Zhao Chongyang to scare the snakes, take a hot air balloon to rise above the jungle, throw firecrackers and grenades from the air, although the casualties caused to the enemy are limited, but the key is that no one knows what it is, as soon as they hear the muffled thunder everywhere in the forest, most people will choose to get out of the jungle to escape, and the people who are ambushed outside are waiting to arrest people.

After the arrival of Qiu Qionghu's special combat team, the army accelerated the pace of the offensive. At the end of June, the ships of the navy sailed directly to the city of Wrestling, and then the army went ashore to block the four gates, and the artillery on the steam ships had already loaded their ammunition, and they began to fire when the commander-in-chief gave an order. The special combat soldiers of Wu Song and Qiu Qionghu were ready to attack the city.

At this time, Li Liangcai was still in the palace to convene an emergency meeting of the ministers. Because he received a report yesterday that the day before yesterday the Song army had attacked Shuncheng, which was more than 200 miles away from the capital, according to his calculations, the Song army might arrive at the capital in the sixth day. Tanma reported that the returning naval army would arrive at Wrestling City by the afternoon of the fourth day at the latest.

Therefore, Li Liangcai, who had planned to pack up the gold and silver treasures and flee into the northern mountains with the princes and ministers, no longer planned to escape, and waited for the arrival of 50,000 sailors to prepare to defend the city and wait for reinforcements.

Thundered... Thundered......

Dozens of muffled thunder roared like a burst of thunder, and the first batch of soldiers defending the city of Annam who had not yet run into the palace were startled by the sound of siege artillery.

After the Annan guards guarding the water gate saw that after a muffled thunderstorm, there was immediately a feeling that the earth was shaking and the mountains were shaking, and the city walls on both sides of the water gate immediately stepped upside down, and the defenders on the city wall were killed and wounded, and wails were heard everywhere. Seeing that the city could not be defended, the defender hurriedly sent a group of soldiers to the palace to deliver the message, and he rushed to the mouth of the city wall with the remnants of his army, trying to buy time for the king of Annam to escape from the capital.
