Although Huang Taiji thinks that this is not very reliable, after all, the current Ming army is not the Ming army of the year, and the current Ming army should actually be the Yu family army, and the combat power of the Yu family army is definitely not comparable to the Ming army during the Battle of Salhu.

Therefore, it is very doubtful whether such a concentrated force can work all the way to fight first, and what is even more tragic is that now the Mongolian Eight Banners have collapsed, and most of them have turned against each other, taking advantage of this opportunity, the Mongolian tribes have also begun to send troops, launched an attack on their Houjin, and restrained a large number of Qing troops in western Liao.

There is one more thing that makes Huang Taiji feel worried, that is, this year due to various reasons, Houjin has completely cut off the channel of importing grain, and the agricultural situation outside the customs itself is not optimistic this year, the weather is dry after the summer, many farmlands have no water available at all, and the grain production has been reduced, and now the weather has turned cold, Yu Xiaotian chose to go out of the customs at this time to wage war against Houjin.

After the initial victory of the Yujia army, they began to send a large number of cavalry to destroy many places in the Houjin, setting fire to many crops that were about to be harvested, so that even if the Houjin army won the war next, they would face a severe famine after winter, and a large number of people would definitely starve to death this winter.

The two consecutive years of starvation had already stifled the possibility of Jiannu's army expansion, and because of the lack of troops, they were unable to launch an invasion of Guannai, so they had to devote more manpower to agricultural production, which also led to their failure to increase their strength in the past two years.

In addition, in order to resist the future war launched by the Ming army against the Later Jin, Huang Taiji devoted all the strength of the Later Jin to build various firearms, which took up a lot of human, material, financial and other resources, which made their economic situation even worse, and they completely fell into a difficult situation.

Now although they have planned to gather heavy troops and eat the soldiers and horses of the Yu family army all the way, even if they mobilize all the troops that can move, there are only more than 30,000 people, and they will no longer be as strong as they were back then.

Even so, Huang Taiji also knows that this battle is related to the survival of the entire Houjin, if they don't fight, they will be forced out of the gate of Shengjing sooner or later, they still can't hold on, the grain reserves in Shengjing have bottomed out, the future will be frosty, the temperature will drop sharply, and their days will be very, very sad.

Their only chance is to completely defeat the "invading" Ming army while the weather has not completely cooled down now, so relying on the captured grain, they are estimated to be able to survive this winter, otherwise I am afraid that famine will be able to completely knock them down after winter.

So Huang Taiji finally made up his mind, gathered a number of battleable soldiers, and went to Haizhou to fight a decisive battle with Yujia's army, and if they win, they can get a chance to survive, and if they lose, it will announce that the Great Qing State they have established for a short time will be completely wiped out.

This time Huang Taiji also made the greatest ruthlessness, handed over the command of this battle to his young brother Duoduo, and appointed him as the general who was ordered, with the seventh brother Abatai as the deputy, commanding nearly 40,000 troops, exhausting all the elites available to Houjin, and with the army also requisitioned a large number of coats to help the war, known as the army of 100,000, went to Haizhou to block the Ming army led by Xiaotian, and fought to the death with it in Haizhou.

On the seventh day of the ninth month, Yu Xiaotian's division, including Yu Jiajun and Zu Dashou's Guanning army, a total of more than 40,000 elites, arrived at Xining Fort on the west bank of the Daliao River, easily took Xining Fort, and then began to cross the river and advance in the direction of Haizhou.

At the same time, the Jiannu army under the leadership of Duoduo and Abatai also arrived in Haizhou, and learned that the Ming army had captured Xining Fort and was going to cross the Daliao River to enter Haizhou (the area of Haicheng in later generations), so they immediately accelerated their march and rushed to the east bank of the Shuangtaizi River to set up defenses and prepare for the Ming army to be in the Shuangtaizi River.

This time, Huang Taiji can be said to have taken out all the goods at the bottom of the box, took out 68,000 taels of silver from the warehouse, and distributed them to the soldiers and generals in the army to reward the generals, and allocated all the red-coated cannons that could be mobilized in recent years to Duoduo, and also raised tens of thousands of catties of gunpowder and more than 3,000 newly built bird guns for his use.

In addition, nearly 10,000 cavalry, more than 15,000 war horses, and more than 2,000 pack horses and mules were mobilized to haul those heavy red-coated cannons.

In short, Huang Taiji took out everything he could, and at the same time ordered the people left behind in Jiannu to go all out to start harvesting grain, supplying the army for food, and making another wintering reserve.

On the tenth day of the ninth month, the Ming army arrived at the area of the Shuangtaizi River under the supervision of Xiaotian, and began to cross the river by bridge, and Duoduo immediately sent cavalry to launch a fierce attack on the Ming army who crossed the river first.

The first group to cross the river was the Guanning army that was used as cannon fodder by Yu Xiaotian, but the Guanning army that crossed the river was attacked head-on by the Jiannu cavalry, and the army retreated to the opposite bank.

After Yu Xiaotian personally led the main force to arrive, he suppressed the Jiannu cavalry on the opposite bank with artillery, and then sent sappers to build temporary bridges in both the downstream and upstream at the same time, and began to force the Shuangtaizi River.

Two battalions of infantry and a company of artillery of Yujia successfully crossed the river overnight, attacked the cattle pressure post and captured the cattle pressure post, which seized a bridgehead on the east bank of the Shuangtaizi River and established a relatively stable defense line.

Duoduo was shocked when he heard the news, and immediately sent a large number of cavalry to storm the headquarters of the Yujia army that had crossed the river in advance in the area of Niupressiyi, and two battalions of Yujia's infantry and a company of artillery were attacked by nearly 10,000 Jiannu's army at Niupressiyi.

More than 2,000 infantry of the Yujia army, relying only on the extremely rudimentary fortifications of the cattle pressure post, blocked the onslaught of the Jiannu army, and covered more Yujia troops to break through the Shuangtaizi River from the bridge and reach the east bank of the river.

As the Yu family army crossed the river more and more, the son of Abatai, who led the army to attack the Niu Press, Bolo, was killed in a cannon, which made Duoduo realize that he could no longer defeat the enemy Yu Bandu and block the Ming army from crossing the river, so he ordered to shrink his forces and build fortifications in the lower reaches of the east bank leading to Haizhou, preparing to fight to the death with the Yu family army who crossed the river.

On September 13, the main force of the Yujia army crossed the Shuangtaizi River, and the follow-up Guanning army, under the leadership of Zu Dashou, detoured to the downstream area, re-selected the place to cross the river, and crossed the river from the downstream to cooperate with the main force of the Yujia army to form a flanking attack on the Houjin army.

After a short rest, on September 15, Yu Xiaotian arrived at the place where the Jiannu army was stationed, and the approximate location was also in the area of Panjin City in later generations, where the terrain was flat and open, which was very suitable for the main forces of the two armies to fight.

For Jiannu, they have the advantage of geographical advantage, because they arrived here earlier, have already built certain fortifications in this area, and built some artillery fortifications, arranged more than 30 red-coated cannons they brought this time, and prepared for a decisive battle.

As for Yu Xiaotian, the Yu family army under his command went on an expedition, and his foothold on the battlefield was not stable at the beginning, and he was slightly at a disadvantage in terms of troops.

However, after Yu Xiaotian observed the battlefield through the telescope, he listened to the news fed back by the scouts, made a general judgment on the battlefield, and did not feel nervous at all.

Early the next morning, Yu Xiaotian exhausted his elite and put his troops into the battlefield, and began to take the initiative to attack the Jiannu army.

The two sides immediately launched a major battle related to the life and death of Houjin in the area of Panjin City in later generations.

Although Duoduo led his troops on this expedition and brought with them the most elite men and horses of Jiannu, including some of the white-armored Baya soldiers they were proud of, as well as a large number of firearms, they were unable to take advantage of the attack of the Yu family army at all.

The cavalry of the two sides first had a head-on contact, and Jiannu thought that their cavalry was quite strong, but he didn't expect that the cavalry of the Yu family army was not weaker than them at all.

Among the cavalry of the Yujia army, the main force is the newly formed Mongolian cavalry battalion, and the rest are all cavalry teams mainly from the northerners trained for many years, although these Mongolian cavalry were not the opponents of the Jiannu cavalry before, the key is that they have poor equipment quality, and they belong to different Mongolian departments, and there is no unified command and dispatch, so they are not the opponents of Jiannu.

But now that they have been disrupted and reorganized, the situation is very different, first of all, they have obtained extremely sophisticated weapons and armor, and the war horses are also the best war horses provided by the Mongolian tribes, including the war horses have also been protected by light armor, although Yu Xiaotian did not equip them with firearms, but they were equipped with the best riding bows, and after having these armor weapons, their combat power immediately increased a lot.

In addition, they have obtained a good command and dispatch, the officers are all from the family army, these Mongolian cavalry themselves are straightforward, after getting good treatment, each of them is very concerned about filial piety, they have never lacked courage, and now after becoming an army, it has become even more courageous.

So when the cavalry of the two sides came into contact, it was difficult to separate the immediate fighting, and Jiannu found that their cavalry could not take advantage of the cavalry composed of these Mongols in the Yujia army, and after a fierce battle between the two sides, they flickered into losses, but the losses on the Jiannu side were much higher than those on the side of the Yujia army, so Duoduo had to withdraw the cavalry and began to turn to positional warfare.

This adjustment, it can be said that the fate of Jiannu was immediately decided, no one in this era of positional warfare can be the opponent of the Yu family's army, don't look at them, Jiannu is also equipped with a lot of arquebuses and red-clothed cannons, but when facing the infantry of the Yu family army armed to the teeth, they can only be beaten.

Yu Jiajun pulled the artillery of the army to the front of the formation, lined up to build a temporary artillery base, and then began to attack each other with the artillery team of Jiannu on the opposite side.

The artillery of both sides fired desperately, and the shells whistled and staggered in the air, smashing into each other's positions, but in terms of artillery warfare, Jiannu was at best in front of the artillery of the family army, at best, it could only be regarded as the level of kindergarten children, while the artillery of the family army belonged to the category of college graduates.
