(Looking at the front, it is indeed Chen Yuan and Li Nian guarding the north bank of the Yellow River, the error in the article has been changed, and it may not be corrected, I hope you will point it out.) ）

Hancheng, also known as Xilongmen at the time, originally belonged to Feng Yi County, Li Yuan called the emperor, withdrew the county and changed the state, and Feng Yi County became the same state.

Later, because Li Po attacked Jinyang and quickly moved south to occupy Hedong, Tang set up a platform on the Shaanxi East Road to protect Li Po.

The general of Tiance, who was the former commander of the march of the Eastern Shaanxi Province, and Li Shimin, the king of Qin, then concurrently served as the secretary of the Shangshu Order of the Eastern Shaanxi Province, so that Li Shimin's power was infinitely magnified.

Almost the entire northern part of Chang'an, the military and political power under the rule of Li Tang on the west side of the Yellow River was concentrated in the hands of Li Shimin, the king of Qin.

But then again, this is different from the northwest, the crown prince Li Jiancheng led the troops and guarded it, holding more than 100,000 horses, so Li Shimin's power was also greatly restricted.

At this time, due to the needs of the war, Li Shimin changed Hancheng County to Hanzhou Administration, separated from Tongzhou, and governed three counties, with Tang Jian's headquarters stationed in Hancheng and guarding the Pujin Bridge.

Li Po led the army to storm Puban, and here at Longmen Ferry, except for the scouts of the enemy troops cruising back and forth on the east bank, there was no movement at all.

Li Shimin also learned that Li Po divided his troops to guard the Fengling Ferry, as if to prevent Li Jiancheng from leading his army north.

In fact, at this point, Li Shimin's various preparations for this battle have in turn put him in a dilemma.

Originally, according to the plan of Li Shimin and his subordinates, Li Po led the army south to attack Puzhou in early February, and it was expected that if the other party moved south after the Yellow River thawed, then Li Shimin would have no other choice but to defend Puban.

can attack before the Yellow River thaws, so Li Shimin has more choices.

His ambition at that time was not just to consume the Jindi troops on the beachhead along the Yellow River, he carefully estimated Li Po's troops, in fact, it also left some room for Li Jiancheng to lead the army north from Tongguan to Hedong.

Is his brother Li Jiancheng's desire to make contributions urgently? Will they seize the opportunity to cross the river to the north? Do you still need to ask?

The prince's military exploits have been thrown out of his younger brother, not to mention the prince, even Li Yuanji, the king of Qi, doesn't he always want to make military exploits before the battle? What's more, it's the crown prince......

Such a seemingly good opportunity was sent to the prince's mouth, and he would still abandon it?

Of course, the brothers have been fighting each other so far, and they have become enemies, and Li Shimin will definitely not save the heart of giving the prince military merits to help the prince stabilize his power.

What Li Shimin saw was that if the prince led the army to cross the river to the north, it must be a division of troops, and Li Jiancheng had also been in the army for many years, and he would not do anything to make Tongguan empty and let Wang Shichong pick up the cheap.

That way, it's going to be a wonderful sight.

The Daizhou Iron Cavalry is the sharpest weapon in Li Po's hands, whether it is at Pujin Bridge or at Longmen Ferry, it is unlikely that he will cross the river on a large scale to participate in the war.

If the crown prince led his army across the river, then he would most likely encounter a brigade of cavalry......

If he is Li Po, he will definitely give the Tongguan defenders a chance to cross the river, lure the Tongguan defenders to the north, and break it in a battle, and in that case, he will definitely give Li Shimin some opportunities.

No matter what the prince is, King Qin has no fault.

This is Li Shimin's wishful thinking that he did not tell everyone about in private.

It can be seen that Li Shimin, the king of Qin, is not only a qualified military commander, but also a qualified king.

If Li Po knew his thoughts, he would definitely be very cooperative, and he would probably discuss with Li Shimin in private, how much advantage should we all take advantage of, and it would not damage everyone's friendship.

If the commanders of both sides of the war can be so calmly in the same stream, the kings may not live long.

Therefore, Li Po seemed extremely uncooperative.

First, he sent troops to seal the ferry on the north bank of the Yellow River, and then led the army to storm Pusaka, which had the meaning of going down to Pusaka first, and then crossing the river for a battle.

At this time, Li Shimin knew that the worst situation had come, the enemy had chosen a stable and conservative strategy, and had a faint upper hand in this battle.

The biggest problem left for him is whether to save Kasaka or not.

At this time, Li Shimin showed his decisive side, and immediately led everyone to return to his hometown when Wen Dayou's coffin returned, and led people to enter Yongfeng Cangcheng and kill Dugu Huaien, except for one aftermath.

Then he left Yu Wenshi and stationed in Yongfeng Cang, and by the way, he cleaned up Dugu Huaien's henchmen and fished out the evidence of the crime.

As for himself, he led 2,000 horsemen to enter Hancheng at night, and at the same time ordered Duan Zhixuan, Hou Junji, and others who were sitting in Feng Yi to immediately cut through the ice, eliminating the possibility of the enemy crossing the river at Longmen Ferry in one fell swoop.

With the development of the strategy of the two armies, the Tang Army was undoubtedly at a disadvantage.

This is easy to see clearly, Li Po implemented his own strategic intentions, but the Tang army could only adjust its strategy as the war progressed, and the advantages and disadvantages were almost clear at a glance.

And at this moment, the offensive and defensive trend on the battlefield was clearly displayed.

……………………………………

Kasaka, after two days of tentative attacks, the walls of Kabasaka have been mottled with blood.

The banner of the Tang army was still flying high above the city, but the two arrow towers at the head of the city had collapsed on the second day under the bombardment of the artillery, leaving only the jagged wreckage.

In the next two days, the idea of capturing Pusaka City had risen in Li Po's heart, and the idea of ending this meaningless battle was equally clear.

But in the evening of this day, when Li Po, who had returned to the camp, was about to summon all the generals to come and urge them to lead the army to attack, someone came from the other side.

In his opinion, the Li father and son are quite despicable, and the envoys sent by Li Shentong are just using the method of agitation.

At this time, he dared to send someone here, thinking that he Li Po was quite easy to conceal, right?

But what made Li Po depressed was that this time the Li father and son seemed to have succeeded again.

Originally, saying that Wen Dayou was dead and wanted to send his coffin back to his hometown, please send someone to respond well, so as not to accidentally injure innocent Yunyun, Li Po didn't pay much attention to it at first.

Even if Wen Dayou is Wen Yanbo's brother, if he dies, he will die, you don't stay in Jinyang, but you go to work for Li Yuan, how can I be courteous when you die? I know who you are?

But after thinking about it, I really have to have a high-level reception next......

In fact, the truth is not very profound, Wen Yanbo is now his long history, and he is also the Jinyang Order, not only his confidant, but also no worse than anyone else in terms of power.

And although this person doesn't speak very beautifully, it is extremely rare not to say it in terms of talent, and it is also very easy to use, and to this day, the Youzhou descendant of that day has already crossed the threshold of descending people, and has become one of the most trusted and reused people under his command.

If someone else's brother is dead, if you ignore it, deal with it hastily, and let others see it, I'm afraid it will become an extremely chilling thing.

You know, Li Yuan has put on a posture, if you do the opposite, what will happen?

Thinking of this, Li Po couldn't help but scold in his heart, Li Yuan, a bastard thing, was extremely treacherous when he was in Jinyang, and now that he is the emperor, it seems that he has intensified, and even used such subordinate methods.

So, on the third day, the battlefield calmed down, and Li Po led people to welcome Wen Dayou's coffin on the riverside, but Li Po was angry, and the accompanying people, whether it was the Tang soldiers, or the Wen family's subordinates, or even the envoys sent by Li Yuan to visit Empress Xiao in Jinyang, were all driven away by Li Po.

It's nothing if you suffer once or twice, if you allow your messenger to cross the river one step later...... Damn, my Li Po's name is written upside down.

Don't underestimate the buffer of this period of time, it interrupts the course of the battle, gives the Tang army in the city a chance to breathe, not to mention, it will definitely affect the morale of the besieging army.

And it is also to lead the spirit back to his hometown, and when people see it on weekdays, they must also hide farther away, so as not to get bad luck, and now they have traveled all the way in the army, what do you let the officers and soldiers in the army think? There will definitely be no mourning effect, but it is likely to make everyone feel bad luck and unlucky......

After that, Li Po also had to be distracted, and wrote two letters one after another, one to Chen Xiaoyi, the county guard of Taiyuan County, asking him to prepare for Wen's funeral, and the other to his wife Li Bi, asking her to appease Wen Yanbo.

For a person who had never met at all, had never even heard of his name, and died in Chang'an, Li Po admitted that he was indeed disgusted by Li Yuan.

Sending the coffin away, he still has to face Pubancheng, at this time, Li Po himself felt shaken and his morale decreased a lot, not to mention the soldiers under his command.

So Li Po simply suspended the army for another day, and summoned the generals of all departments in the evening, so that they could appease the morale of the army and boost morale, and then on the second day, he had to personally inspect the four battalions, regardless of the "danger", make the armor bright, and ride high on the war horse, so that more soldiers could see his appearance, and he made a show for people to see.

Despite this, the army was still affected, and the soldiers who had rested for two days only landed in the siege of the city twice during this day's siege battle, which still seemed to be barely strong, which made Li Po more and more annoyed.

This is very similar to the original defense battle under the city of Liaodong, this intermittent siege method is very stupid, which will shed a lot of blood, and the resulting frustration will haunt the whole army, and with the extension of time, it will eventually lead to the most terrible consequences.

That night, Li Po had to summon the generals again, and ridiculed the incompetence of the generals in a very mean tone and words, and set a two-day deadline for the generals.

He was very patient before, but seeing that the war was likely to drag on, based on his keen battlefield instincts, patience was immediately replaced by nervousness, and he wanted to take Kasaka as soon as possible......
