The climate in the Hetao Plain in mid-June is dry and sunny.

This kind of season is actually very suitable for horseback riding on the endless grassland.

But at this time, the place was filled with smoke.

Multiple Jin Army scouts were scattered throughout the country, and they carried out their tasks efficiently. Their field of vision covered a large area of ​​plains, and they could even clearly count how many blades of grass a passing sheep had eaten.

Since the Song Army and Wang Bolong's Jin Army had been confronting each other for a period of time, the period of silence that both sides had entered was undoubtedly broken by the arrival of the main force of the Jin Army.

Countless urgent messages were sent to Anbei City, Pingrong City, and Dongsheng City.

All intelligence tells the Song Army that more Jin troops are coming.

As for how many there are, no one knows.

Regarding the Yinshan battlefield of the Seventh Song-Jin War, someone later discovered when decrypting confidential documents that both Yue Fei and Wu Jie knew that Jin Wushu had deployed 200,000 troops in Yinshan, but the commander-in-chief Yu Yunwen who was at the Yinshan battlefield did not know.

From this point of view, it is very unfair to Yu Yunwen.

Some people privately scolded the Zhao family for deliberately abandoning Yu Yunwen, while others praised the Zhao family for their tight control over the battle situation, and explained that if Yu Yunwen were to know the true strength of the Jin army, it would have a great psychological impact and pressure on Yu Yunwen.

The Seventh Song-Jin War was also accompanied by the Song Dynasty's full-scale use of troops against Xixia. The northwest troops could no longer be allocated to support Yu Yunwen, so Yu Yunwen had to be allowed to hold on in Yinshan.

Sometimes, those who don’t know are braver.

On June 17, Yu Yunwen received the latest intelligence. This intelligence was not very detailed. It only used the phrase "Jin soldiers everywhere" to describe the large number of Jin troops.

At that time, Wang Bolong commanded an army of 50,000 when he went south, which can be described as "Golden soldiers everywhere".

Therefore, until now, all the intelligence cannot support Yu Yunwen's prediction of the true strength of the Jin Army.

However, the new wave of reinforcements of the Jin Army undoubtedly made Yu Yunwen smell an unprecedented crisis.

However, even if Yu Yunwen was extremely talented, he would never be sure that the Jin Dynasty would go to Yinshan to suppress an army of 200,000.

During the first battle between the Song Dynasty and the Jin Dynasty, the combined armies of Zong Wang and Zong Han amounted to no more than 100,000.

In the Second Battle of Song and Jin Dynasties, when Zhao Ning had just crossed over, the total strength of the Jin army reached 150,000, which had already caused Hebei and Hedong to scream.

The third war between the Song Dynasty and the Jin Dynasty was an all-out southward march from the east, middle and west, and the Jin people only mobilized 250,000 troops.

As for the Sixth Song-Jin War, the total size of the armies of Zong Wang and Zong Han was only 150,000.

You know, as long as the number of troops exceeds 10,000, it is considered a large corps.

Anyone who believes in the records of hundreds of thousands of troops being mobilized at every turn during the Warring States Period is a fool.

"Sun Tzu's Art of War" has this record: Those who raise an army of 100,000 and march thousands of miles, at the expense of the people and the support of the public, spend thousands of gold a day; there are commotions inside and outside, and they are lazy on the road and can't do anything, there are 700,000 families.

According to calculations in "The Art of War", the national mobilization rate in ancient China was about 3% to 4%, with 5% being the limit.

After all, not all countries want to mobilize all their people like Xixia.

Two hundred thousand troops were pressed against the Yinshan Mountains, accounting for 2% of the Jin Kingdom's tens of millions of people. Together with the defenses in Hebei and Liaodong, the two hundred thousand troops together accounted for 4% of the total population. This had already touched the red line.

However, as a country like the Jin Kingdom that has just been founded and still maintains strong barbarian habits, the legitimacy of its political system has not yet been fully established, and the legal responsibility system for the people cannot be fully determined. This can help the Jin Kingdom increase its mobilization rate.

As Zhao Ning said, if the Jin Kingdom is forced to a dead end, a million-strong army can be squeezed out, but that is the way to go during a desperate period.

At this time, it was clear that Jin Guo was at the end of his rope.

Yu Yunwen was both good at fighting and well versed in internal affairs. He used the Song Dynasty template to calculate the Jin Kingdom, but there were deviations.

Naturally, it was impossible for him to believe that Jin Wushu would send an army of 200,000.

This undoubtedly put tremendous pressure on the Yinshan defense line.

At the same time, because they did not know the specific number of enemies, the Song army maintained a high combat effectiveness.

On June 19, Han Chang and Wang Bolong met on the bank of the Yellow River.

The main force of the Jin army was all gathered outside Anbei City, known as an army of 400,000.

At this time, standing outside Anbi City and looking out, the rolling tents were like the waves of the sea, and it was really impossible to see the end at a glance.

On the evening of June 19, Liu Shan, the envoy of the Jin Army, entered Anbei City.

In front of many Song generals, Liu Shan said arrogantly: "The Song Kingdom has invaded the territory of the Jin Kingdom without authorization. Now the Emperor of Jin has sent an army of 400,000 to the west. The barbarians from all directions have surrendered. If the Song army can surrender in a wise manner, the emperor can reward you with great rewards and make you marquis."

Wouldn’t it be beautiful to pay homage to the prime minister!”

His words undoubtedly aroused the anger of many Song soldiers. They all stood up and wanted to beat Liu Shanqun to death on the spot.

In the end, Yu Yunwen let him go.

In the next two days, the intelligence collected by Song Army scouts showed that the number of Jin troops was far greater than he had expected.

Early in the morning on June 22nd, just after dawn, the earth-shattering sound of war drums could be heard outside the city.

Anbei City was surrounded on all sides by the Jin army.

Forty heavy artillery pieces were displayed in the east of the city, and countless goose carts and caves were displayed in front of the army.

Countless armored infantry, archers and crossbowmen were gathered under the three city walls on the south, west and north sides.

At nine o'clock in the morning, the Jin launched an attack on Anbeicheng.

Forty heavy artillery roared angrily, and huge stones smashed against the newly repaired Anbei City wall.

Intense artillery fire also rang out from the top of the city.

After half an hour of fighting between the two sides, the walls of Anbei City collapsed.

The Song army was forced to move its artillery in advance.

After demolishing the walls of Anbei City, the Jin army did not rush to attack. Instead, they built momentum outside the city in an attempt to put further psychological pressure on the Song army.

This was far from over. The Jin army also launched intensive long-range attacks on the three walls of the southwest, north and south.

Pieces of arrows flying two miles across rose up from the ground, leaving moving shadows on the ground, rushing toward the city head, and hitting the city head and inside like a heavy rain.

Such horrific scenes were staged on the south, west, north and south sides at the same time.

The Song army also fought back in kind. A dense rain of arrows poured from the top of the city, as well as iron cannons, tearing bloody streaks in the Jin army's formation.

There were even ten crossbows placed on each of the three walls of the city. Those arrows actually flew into the main formation of the Jin army, washing over the ranks of the armored infantry, making a clanging sound of metal impact.

In this scene, the two sides faced off for another half an hour, almost using up all the arrows and long-range ordinary trebuchet shells.

Obviously, the Jin army wanted to conquer this fortress on the edge of the Yellow River at all costs.
