There are 40,000 Annan defenders in the city.

Outside the city there were only Yang Zaixing's 6,000 men and Yang Yao's 1,000 marines.

It was a bad idea to defend blindly. As a veteran general, Yang Ying'er led 20,000 troops out of the city to test.

He sent five thousand soldiers to fight, and the rest of the troops were responsible for plundering the formation.

Yang Zaixing only sent 3,000 men, and the battle only lasted for more than ten minutes. Annan's army could not hold up the firearms and was defeated in a mandarin duck formation.

Yang Ying'er sent troops to respond. At this moment, the Ming Dynasty ships on the Taiping River suddenly fired at Yang Ying'er's Chinese army.

During previous battles between the two navies, the Ming Navy had been hiding the range of its artillery.

Yang Ying'er never expected that the artillery could shoot so far.

The central army of Annan's army was in chaos, and Yang Zaixing and Yang Yao took the opportunity to rush out with their entire army.

Yang Ying'er's troops scrambled to escape, and were captured by the Ming army. Nearly ten thousand people were killed, and thousands of soldiers were scattered in the countryside. With only two to three thousand soldiers, he fled back to the city in embarrassment and did not dare to come out.

The Annan garrison in the city suffered a direct loss of nearly half.

Yang Ying'er was so frightened that he could not hold on and wrote a letter back to Shenglong Mansion to request more troops.

"Stay here to attack the city?" Yang Yao asked.

Yang Zaixing said: "Kill all the prisoners and kill them all the way to Hanoi!"

Yang Yao said: "I'm afraid the military rations are not enough."

Yang Zaixing said: "Annan will send troops to fight against Champa and Chenla, and also divide the troops to defend Lang Son. How many troops can this small country have left? Just go around here and go against the Taiping River to kill Thang Long. The city in front will definitely

The troops are empty. Moreover, the Annan garrison here needs food, and the food and grass must be transported along the Taiping River, and the cities along the way are our food stations!"

"Okay!" Yang Yao is also a risk-taker.

Yang Ying'er stood at the top of the city and watched the Ming army retreat.

The ships of the Ming army carried grain and a small number of soldiers, while most of the Ming army walked along the river. They just walked around the city in a swagger, not caring about the grain road or the rear!

Before leaving, they also collected all the ships outside Wu'an Prefecture.

There were only a few dozen light cavalry, half of them were exploring the front and the other half were on guard at the rear.

Soldiers can't walk fast wearing armor, so they need to stay out of the enemy's sight and put the armor on a ship for transportation.

The fleet also divided into several ships, some exploring the way forward and some on guard at the rear to prevent the enemy from suddenly attacking and leaving the infantry with no time to collect armor from the ship.

How could Yang Ying'er let them leave calmly? He led his elite troops to attack at night that night.

As a result, the Ming army took off their armor when they were on their way, but took the armor from the ship and put it on before going to bed.

Yang Ying'er's night attack failed and he fled back to Wu'an Prefecture in embarrassment.

The next day, Yang Zaixing sent 500 elite troops to suddenly speed up in a boat.

Unexpectedly, they arrived outside the city on Beijiang Road ahead. The defense there was empty, with only a few hundred people guarding the grain and grass that were going to be transported to Wu'an Prefecture.

Take it in one fell swoop.

This city is only a hundred miles away from Thang Long, the capital of Annam!

Yang Ying'er, who was left behind, was impatient. Although he knew the danger was high, he could only lead his army to pursue him.

Another big defeat on the way!

You must know that in Annan's heyday, the army's combat effectiveness was overwhelming. However, when the Northern Song Dynasty army conscripted and mobilized northern elites to fight against it, Annan's army was still beaten and retreated.

Today, Annan has long since died. Not only has he been disarmament, but corruption and expropriation in the military has become more serious.

As for the morale, it was not much better than that of Song Huizong's Xiang army.

In the city of Shenglongfu, when they learned that the Ming army was hundreds of miles away, the civil and military officials were so frightened that they quickly gathered their belongings.

Zhang Boyu advised: "Your Majesty, please quickly hunt west and take hundreds of officials and soldiers to the Ailao Mountain to temporarily avoid the enemy. The Ming army wants the old land of the Song Dynasty, just give it to them, and you can get it back in the future!"

"How to get it back?" Li Yanghuan asked.

Zhang Boyu said: "The late emperor was also severely defeated by the Song State, but after the Song State withdrew its troops, it harassed the Song State's borders every year. The Song State could not bear the harassment and returned the territory it had stolen to us. This time

You can also do this. After the Ming Dynasty withdraws its troops, next year we will send troops to harass the border."

"Excellent, let's go hunting in the west." Li Yanghuan said.

Yang Zaixing is still a hundred miles away, and the leader of Annan has already run away with all the officials...
