As for the navy, they did not want to let the army stand alone and rob all the credit, although they were mainly responsible for providing supplies to the army and transporting the army to land, they still transferred a part of the navy to launch a clearing operation against the islands along the way that were currently under the control of Jiannu.

After Jiannu cleaned up the old department of the Dongjiang Army, he more or less obtained some ships, had a very weak naval division, and also controlled the islands along the coast, but in front of the navy of the family army, the fleet of sailors like them was not enough at all.

The entire Jiannu limited sailors were wiped out in front of the artillery of the Jiajun Navy almost instantly, either they were beaten into slag and sank into the sea, or they were directly destroyed on the shore, and individual ships were captured by the Yujia Navy.

In the past, the navy's warships first shelled fiercely, and then covered the landing and assault of the navy, and it can almost be said that they did not encounter decent resistance, and basically cleaned up the Jiannu defending the island.

As the army launched its operation, the navy also conquered and controlled the islands along the Liaodong Peninsula in a short period of time, destroying Jiannu's extremely limited water power.

At the end of August, the navy organized its own offensive against Phi Dao, with dozens of warships in operation and a full naval battalion to land.

In less than two days, Phi Dao was captured by the navy, and more than half of the hundreds of Jiannu defenders defending the island were killed, and the rest were all captured alive, and none of them escaped. It also seized three self-cast Hongyi cannons of the Jiannu garrison on the island, which were directly scoffed by the navy after inspection and smashed as scrap metal for recycling.

And after Yu Zhenshan led the troops to capture Zhenjiang Fort, he did not stay too long, and after cleaning up the surrounding villages and forts of Jiannu, he immediately went upriver and went towards Yizhou (which later belonged to Chao-Xian's Yizhou), at this time Chao-Xian Shang was still subordinated to Jiannu, although it was a little unsafe in the past two years, but after all, Yu Xiaotian did not have time to deal with them, so they did not dare to re-declare that they would no longer surrender to Jiannu.

But this time, before Yu Xiaotian's action, he sent someone in the name of the Ming court to go to Chao-Xian to inform the Ming Dynasty that he was going to attack Jiannu, and asked the king of Chao-Xian to re-choose a side, either to send troops to participate in the conquest of Jiannu, or to wait for the Ming Dynasty to clean up Jiannu's thunderous anger at them.

The king of Chao Xian is a two-faced dilemma, this era because of the news blockage, they are not very clear about the current situation of the Ming Dynasty, but according to the previous situation, they dare not believe that the Ming Dynasty can cheer up in just a few years, and can fight against the Jiannu army.

So he didn't dare to offend Daming, but he didn't dare to offend Jiannu either, and at this time he fell into a dilemma, and couldn't make a decision for a while.

Yu Zhenshan led the army to attack Zhenjiang Fort this time, in fact, he wanted to knock on the mountain and shake the tiger, let the Chao-Xian side see how powerful the Ming Dynasty was, let them understand who to follow in the future, and by the way, also blackmail the Chao-Xian side.

This is also the reason why after he conquered Zhenjiang Fort, he did not immediately attack the hinterland of Liaodong, but instead attacked the Yizhou side.

At this time, Yizhou was under the actual control of Jiannu, because it was necessary to monitor the Chao-Xian side, and a group of Jiannu soldiers and horses with strong troops were stationed here, and Du Du was in charge here.

Du Du was defeated by the Yu family army in Guannei, and finally escaped back to Liaodong, and was arrested and imprisoned by Huang Taiji for a period of time, cutting him off the title of Baylor, but later considering Du Du's talent, he released Du Du and let him sit in Yizhou, responsible for monitoring the movements of Chao Xian.

This time Yu Zhenshan led the army to attack Yizhou, which is considered to have met this old acquaintance again, when Yu Jia's army blocked the way of the Jiannu army in Tianjin, Du Du led the vanguard to try to open up the way, that is, the seventh brigade led by Yu Zhenshan who met in Tianjin Wei fought a few battles with Yu Zhenshan, and was beaten back by Yu Zhenshan with a disgraced face.

This time Yu Zhenshan led the troops to attack Yizhou City, and happened to meet Du Du again, the two of them were also enemies, and Du Du led the army out of the city immediately and released the Yu family army, preparing to use his newly trained musketeers to touch the Yu family army and decide with the Yu family army.

How could Yu Zhenshan be afraid of this guy, he immediately ordered his troops and horses to be released, and both sides lined up in a horizontal formation, slowly approaching each other, and the artillery on both sides also fired their own artillery to shell the enemy, but relatively speaking, the artillery team on the Jiannu side was weakly exploded, and as soon as the artillery bombardment fell, their artillery team was almost basically dumbfounded.

When the distance between the two sides was about two hundred paces, Du Du suddenly sent a cavalry to launch a surprise attack on the Yu family army led by Zhenshan, and the Yu family army immediately stopped advancing, contracted the front, first blocked the enemy's attack with a hollow phalanx, and then used dense firepower to kill and injure a large number of Jiannu cavalry, so although Du Du's tactic is very beautiful, but in the face of absolute strength, it still did not play any role at all, after the cavalry's sneak attack was defeated, The Yu family army under the command of Yu Zhenshan immediately turned to fire at the musketeers under Du Du's command.

And the Jiannu fire-spearmen under Du Du are all ordinary smoothbore bird guns, with a range of less than 100 meters, at such a distance, shooting at the Yu family army and playing the game of shooting the party is simply bringing humiliation on themselves.

As a result, the Jiannu fire-gunner watched as Yu Jiajun's army began to fire a volley of guns at them at a distance of about two hundred paces, using the tactic of three shots, but they only had dry eyes, but they couldn't reach each other.

So Du Du had to let his musketeers line up to withstand the fire of the Yu family's army, and marched forward, trying to get into the effective range of their fire.

However, at a distance of 100 paces, it became a place for the bones of the Jiannu fire-gunners, and a large number of Jiannu fire-gunners were knocked to the ground one by one by the infantry guns of the Yu family army as if they were being shot on the way forward, and before they reached the effective firing range, they had already been beaten in scattered pieces and lost the ability to fight back.

Seeing that the situation was not good, Du Du knew that something bad was wrong, and quickly ordered the troops to be collected and withdrawn to the city of Yizhou, but Yu Zhenshan gave the order to charge at this time.

The cavalry was in front, the infantry was behind, and the Yu family's army was the best at white-knuckle charge, if you use the words of the little devil, it is the pig burst tactic.

The infantry of the Yu family army, with their guns on their bayonets, roared one by one and began to rush towards the Jiannu army, which could almost be said to be unparried, and under the assault of the combination of infantry and cavalry of the family army, the whole army collapsed.

Although Du Du was able to escape back to Yiju City in the end, the 3,000 Jiannu soldiers he brought out were only less than 1,000 people left, and the rest were left outside the city, becoming corpses that were gradually cold.

Yu Zhenshan ordered to set up artillery to attack the city, Du Du led the remnants of the defeated army to carry it to the death, after two days of fierce fighting, the city of Yizhou was broken, Du Du knew that the crime was unforgivable, and it was impossible to break through and escape, so after the army surrounded his mansion in the city, when he was attacking the mansion, he ignited a large amount of gunpowder hoarded in the mansion, and killed himself, not to mention, but also killed some of the last remaining Jiannu soldiers in the mansion.

Even the more than 100 soldiers of the Yu family who were attacking his mansion also became victims, the entire mansion was razed to the ground, and there was human flesh and blood everywhere, and the center of the explosion even blew up a big crater.

The city of Yizhou was broken by the Yu family army in a short time, and the news of the defeat of the Jiannu army soon reached the ears of the king of Chaoxian, and he knew at this time that the current Ming army was not the previous Ming army.

The Ming army that is here now is a terrible army, and the Jiannu army, which is already very fierce in their eyes, is simply a dish in front of this Ming army.

And their soldiers and horses were originally the five scum of the war, and they couldn't be equipped with anything, and they had no morale, and now if they offend the Ming Dynasty, destroying the country is a matter of sight.

Therefore, the king of Chao-Xian hurriedly announced that he would no longer obey the dispatch of Jiannu, and arrested some of the Jiannu personnel who remained in Hancheng and sent them to Yizhou to be handed over to the Ming army for disposal, and tried every means to raise 20,000 taels of silver, and got thousands of stone of grain, and sent them to Yizhou, and also requisitioned thousands of Chao-Xian troops to go to Yizhou to assist the Ming army in attacking Jiannu.

In short, these gestures are to be done, and as for Da Ming, they can't care about the help they provide.

In less than a month, the Yu family army attacked at the same time in the entire Liaodong several roads, and successively defeated the Jiannu soldiers and horses, after the news came to Shengjing, Huang Taiji was shocked, he thought that in the past two years, he tried his best to build firearms, equip the Qing army, and thought that he could compete with the army of the Ming Dynasty, but he did not expect that once the Ming army was in trouble, there was so much bad news from all directions.

The entire Liaodong Peninsula, the original Dongjiang Town's control of zhì, now in just a month's work, was beaten back to its original shape, and was taken away by the Ming army, and Fuzhou was also a few days ago, was broken by the Yu army, the Jiannu soldiers and horses in the Fuzhou area, were also almost wiped out by the Yu army, and very few people fled back to Gaizhou.

Zhenjiang Fort and Yizhou were also quickly captured by Yu's army, and Chao Xian also announced that he would break away from their control and no longer submit to them.

And the Ming Dynasty supervised Yu Xiaotian, personally led the army to the land side, all the way to Dalinghe City and Guangning and other places, the soldiers pointed directly at Haizhou, along the way to attack the city and pull out the village, and the tunbao of Jiannu control zhì was pulled out by them like a tooth, and the Qing army could not stop it at all.

In particular, the action taken by the Ming army this time was to divide the troops into three ways and attack the Houjin on the east and west sides, so that they could not concentrate their forces on the Houjin side to intercept the Ming army.

Either he could only divide his troops to resist the attack of the Ming army from all walks of life, or he could only sit and wait for the Ming army to attack under Shengjing City, and Huang Taiji hurriedly convened the Minister of Civil and Military Affairs to discuss countermeasures.

So in the end, they thought of the Battle of Salhu that year, when the Battle of Salhu was in place, the Ming army also had an absolute advantage in strength, but it was also divided into troops to attack, so that the troops were scattered, and finally by Nurhachi of that year, he gathered troops to break through and defeat the Ming army.

This time, the Ming army divided its troops to attack again, and these civil and military ministers of the Later Jin Dynasty thought that they could follow the example of the ancestor Nurhachi, gather troops, first eat the Yujia army all the way, and then gradually eat all the Ming army.
