I'm not laughing. You have also seen the information of Jinyiwei on the situation of the Bohai Kingdom, and you have also learned some from the Silla side, so you should know that the name of the Haidong Shengguo is no longer worthy of the name, and at this time, if you only attack Jiaozhou and Anzhou, you will not let the Bohai Kingdom attack in a big way.

Moreover, with the current strength of the Balhae State, it is not enough to threaten the Pyongyang Governorate. "Yang Shihou will not easily give up attacking the Bohai Sea.

Before he came to Pyongyang to take up his post, Sheng Shangzhao met him and told him about the future strategy of the Tang Dynasty. The establishment of the Pyongyang Governorate was to prepare for the later attack on the Bohai Sea and the Khitan, and the stronger the Pyongyang Governorate, the more beneficial it would be to the future strategy of the Tang Dynasty.

Therefore, after comprehensive consideration, Yang Shihou focused the Pyongyang Governor's Office on the north for a period of time.

The current Bohai Sea is not the so-called prosperous country in the east of the sea a few decades ago.

During the reign of the previous king of Bohai, Da Xuanxi, Bohai had already begun to get rid of big problems, and the internal political situation was chaotic and rebellions were rising one after another.

First, the nobles within the Bohai Sea divided one side and refused to submit to the jurisdiction of the King of Bohai;

The Han Chinese, Khitan and Goguryeo ethnic groups in Liaodong have never been effectively managed by the Bohai Sea, and now they are even more disobedient to the jurisdiction of the Bohai Sea taking advantage of the chaotic political situation;

In addition, the Jurchen, Jin and other tribes that had been conquered before in the Bohai Sea also rebelled from time to time.

This is all an internal problem, on the outside, there are Khitan from time to time to cross the border to plunder, and the old enemy in the north--- Heishui Yan also enters the country from time to time to plunder.

Under the effect of so many reasons, the Bohai Sea at this time has long ceased to be the name of the prosperous country in the east of the sea, but the surrounding enemies are not very strong, and it is not enough to destroy the Bohai Sea.

Even if it is the Khitan Department, it is only entering and plundering at this time, and it has not yet had the strength to defeat the Bohai State.

In history, the Khitan conquered the Bohai State or the Khitan conquered the Xi people, Murowei, etc., and unified the entire Khitan eight tribes before the Bohai Sea was destroyed.

However, at that time, the Bohai Sea was already very weak, so it did not last for a year before it perished.

"Governor, although Bohai is now in internal and external troubles, after all, the strength is still there, if you attack rashly, you have to think about one or two." Du Jianhui was a little not optimistic about Yang Shihou's strategy of the Northern Expedition to the Bohai Sea, thinking that it was a bit risky.

"You have to try, let's try Bohai's reaction with Anzhou first, if the reaction is not intense, we will try later." Yang Shihou did not want to change his strategy.

Although he was in the forbidden army before and served as a general, the forbidden army was not free to send troops.

Without the will of the Holy Lord, the forbidden army could not even be transferred, and the exchange of senior generals every few years also made it impossible for the generals and generals of the forbidden army to move the forbidden army at will.

It's not that Yang Shihou is anti-willful, but the general of the forbidden army is indeed not as good as the governor of the capital or the protector of the capital.

In the Pyongyang Governorate, he has a great deal of autonomy, both in the military and in the civil administration.

He had already made a decision, and it was impossible to give it up just because the people below did not approve of it.

"Since the governor insisted, the lower officials naturally obeyed the order. Xiaguan is mobilizing grain and grass to prepare for the Northern Expedition. "Cui Yuan's ambition is not small, anyway, he wants to expand, since Yang Shihou wants to expand to the north, then follow the other party's wishes, and if he fails, if he succeeds, he will gain more.

In this battle, the governor of Pontu personally commanded, led 5,000 infantry and 2,000 cavalry, plus 1,000 Silla soldiers to supervise the people's escort of grain and grass, a total of 8,000 men. Fight for a surprise attack to take Anzhou!

As for Deputy Governor Du, he stayed in Pyongyang to guard against attacks by the Gong descendants. ”

Du Jianhui did not support his Northern Expedition very much, so Yang Shihou naturally would not let the other party participate, but let the other party stay in Pyongyang to ensure the safety of the rear.

The grain and grass system of the Tang Dynasty is a little different, if it is a forbidden army, it is generally the rear carriage responsible for escorting, and it will also be equipped with cavalry, responsible for protecting the safety of the grain road.

If the amount of grain and grass is large, the people will also be recruited, as in the previous attack on the Uighurs in Western Prefecture.

The Governor's Mansion did not have a back carriage like the forbidden army, so the grain and grass had to be escorted by additional troops to ensure the smooth flow of the grain route.

Li Ye attaches great importance to the logistics of the army, after all, the Northern Expedition of the Song Dynasty in history is not so much that it can't defeat the Liao army, but that the transportation capacity of grain and grass is poor.

In terms of infantry, the infantry of the Song army was not very bad, but the cavalry was not good.

However, the failure of the Song army's northern expedition every time was related to the poor logistics ability of the Song army, and many times the front-line army would be forced to abandon the occupied city and retreat because of the problem of food and grass.

This is also the reason why the Liao army likes to attack the Song army's grain route with light cavalry.

It's okay to retreat once or twice, but often like this, all good fighters have to be delayed, and a hammer battle is fought.

Of course, there were other reasons for the failure of the Song Army's Northern Expedition, and poor logistics capabilities were only one of the reasons.

Li Ye didn't want his army to make such a mistake, and when he conquered the Khitan in the future, he would definitely strengthen the protection of the grain route.

In terms of cavalry, the Tang cavalry is no worse than the Khitan cavalry.

。。。。。。

"Sugawara Gonshal, the matter requested by Your Excellency, the lower officials have already found out, and Tsushima has always been occupied by the Tang Army.

The Han Kou who plundered our Wa Kingdom were basically active in the Wa Kingdom, but there were many fewer pirates in the Silla Territory. ”

In Saikaido, Dazaifu, a Japanese official is reporting to Sugawara Michizane.

Don't look at Sugawara Michizane being degraded, but he has never given up on himself, he is still thinking about the Japanese country, and he is also very curious about what role the Tang Dynasty played in the Han Kou's ravaging of the Japanese country.

When he arrived at Dazaifu, he organized his subordinates to repair the city walls and improve the coastal defenses, and also sent people to Tamna, Tsushima and other places to inquire for information.

"In the past, Han Kou was also prevalent in Silla?" Sugawara Michizane asked.

"It has always been very popular, but since the Tang Dynasty garrisoned the army in Tamna, these Han Kou have become much more honest, and even if they are for the trouble, they dare not offend the sailors of the Tang Dynasty.

A few years ago, there was an incident in which Han Kou gathered hundreds of warships and was defeated by several warships of Datang, and after that, no pirate dared to annoy Datang's sailors. The visitor replied.

"How many warships did the Tang defeat hundreds of Han Kou warships?" Sugawara Michizan really thought it was a little incredible.

"Hui Quan Shuai, this is true, because Han Kou fled to Dazaifu before, and the news is spread from all sides. It is said that the warships of the Tang Dynasty are very powerful, and unlike the common warships, the warships of the Datang can breathe fire, and those weapons can smash any ship, like a thunderbolt descending from the sky.

Although the Tang warships had never been to Dazaifu, according to the merchant ships that came and went, the Datang warships still sailed to the waters east of Tsushima from time to time.

Moreover, it is said that these warships of the Tang Dynasty were carrying gold, silver and jewelry, which were mined from Iwami and Sado. ”

"If that's the case, it's going to be troublesome. In this way, whether it is Han Kou or Ezo people, it may be the support of the Tang people, and it may be the gold and silver of Iwami and Sado.

The official was a little curious, how much gold and silver Iwami and Sado had, so that the Tang Dynasty could support pirates and barbarians without regard for the face of the Celestial Empire. Sugawara Michizane sighed.

"Quan Shuai, the lower officials also heard that the Tang Dynasty has canonized Zhen Xuan, the king of Baekje after Silla, as the governor of Xiongjin Prefecture, I don't know if this matter is useful to Quan Shuai." The person who came told Sugawara Michizane about the news he had just gotten.

Zhen Xuan's controlled territory is separated from Dazaifu by a strait, and there are so many business travelers coming and going, so it is not uncommon for the news to reach Dazaifu.

"After the Tang Dynasty canonized Baekje Zhen Xuan? Why is that? Sugawara was a little shocked.

You must know that Silla has always been a vassal state of the Tang Dynasty, but why did the Tang Dynasty go to canonize Hou Baekje despite Silla's opposition.

Thinking of the establishment of the Pyongyang Metropolitan Government and the Tamna Metropolitan Prefecture before the Tang Dynasty, Sugawara Michizane seems to be aware of a problem.

He actually found it a little hard to believe, if that was really the case, then Datang's ambitions would inevitably be too big.

He didn't believe that the court of the Tang Dynasty didn't know about such a thing, or the emperor of the Tang Dynasty didn't know, it was very likely that the other party knew, or even instructed by him.

If he guessed correctly, then the matter was a big deal.

He also doesn't understand something, the Wa Kingdom did not offend the Tang Dynasty, and it was only a war with the Tang Dynasty two hundred years ago, so there is no hatred.

If you want to talk about hatred, Silla and the Tang Dynasty have fought a lot of battles, and it has nothing to do with the Wa Kingdom.

Although he didn't understand why, Sugawara decided to write a letter and send it to the emperor, hoping to attract attention.
