Mid-Autumn Festival, Hedong County.

Chen Qun, the general of the town army, and Cao Zhen, the general of the town, respectively commanded troops to help, and the east of the river was the gateway to Hebei.

Hedong is also a battleground where Beifu must concentrate its forces to attack; Naturally, the Wei army wanted to gather forces to defend.

Only here can the Wei army assemble and fight.

If Hedong is lost, Beifu, who has the initiative to attack, will be free to choose the direction of attack next.

To get Hedong, there are two roads in Beifu, one is to fight Taiyuan and Shangdang first like the Qin army went east; The second is to attack the vast plains east of Taihang like Han Xin first.

The initiative is in Beifu, and it can gather superior forces and attack a direction where the defense is relatively weak. By this time, the Wei army would have to face the superior forces of Beifu...... Beifu is smooth, and there will be a sweeping trend.

In order to avoid this situation, we can only increase the troops in Hedong, rely on the mountains and rivers here, and fight a decisive battle with Beifu to determine the fortunes of the country.

Even if you can't win the Beifu, as long as you can drag it, you can drag the main force of the Beifu in the four states of Guanlong...... Then there is hope for victory, no matter how bad it is, it can deplete Guanlong's reserves, even if it is fought in the battle of Qin, Zhao and Changping that year, it can also curb the momentum of Beifu going east.

Therefore, the lifeline of the Wei army was in Hedong, and there was no way back.

Withdrawing from Hedong means that the fate of the lost country is irreversible.

Cao Zhen inspected the riverbank, and the horse whip pointed obliquely at the Beifu Water Village in the Weishuikou area: "Who is the commander of the army today?" ”

Protector Pei Qian replied without hesitation: "The bridge building on the south bank and the soldiers and horses of the battalions in the water village are all controlled by Luo Meng, the young secretary of the Ministry of Engineering. This duke Xiangyang was originally from, and during the battle of Xiangfan, he was one of the three governors of the Jingzhou Water Division. ”

"Don't underestimate it."

Cao Zhen sighed with emotion, and Zhao Yan, the Hedong County Shou who accompanied him, agreed very much, and nodded lightly.

At that time, Cao Ren's southern army was so powerful that it was only two days away from being able to complete the assembly and integration in Xiangyang; In these two days, the 30,000 Jingzhou army attacked north against the trend and completely defeated the Wei army in the Xiangfan area.

In addition to the ferocity of the Han infantry, the Jingzhou Navy Division shielded the battlefield and made the main infantry have no worries.

Even if the Wu army betrayed the alliance and attacked, it was the Jingzhou Navy Division that blocked the Han River, so that the Wei army could only withdraw as agreed...... Even if they wanted to break the contract and cooperate with the Wu army to flank the Jingzhou army, they lacked the conditions to cross the Han River.

Chen Qun also carefully observed the south bank and paid more attention to the river.

The Yellow River bends here, with all kinds of whirlpools, so the progress of building a wooden bridge on the south bank is destined to be very slow.

Not only slow, but also easy to destroy.

Even if Romon built a pontoon bridge upstream of the wooden bridge to shelter the pontoon bridge and salvage the fire raft...... As long as the rafts and logs are prepared enough, it is enough to launch a fire attack at night.

If there is a torrent to help, push the logs from the upstream into the current and float down the river, which is enough to wash away the pontoon bridge and wooden bridge.

After careful observation, Chen Qun finally felt at ease and could conclude that the wooden bridge in Beifu could not be repaired this year.

Although Beifu can build a dock in the Weishui Valley, build warships, and large transport ships to facilitate the storming of Hedong; But there is also Fenshui in the east of the river, and you can also build warships and big ships in the Fenshui basin.

As far as the gentle water around Fenglingdu is concerned, if a water war breaks out between the two sides, it will not be a great loss.

It is not like the Yangtze River, the river is twenty or thirty miles wide, like the ocean, the waves are strong and the wind is urgent, and the requirements for the sailor are very high.

Fenglingdu here, it is impossible to have the strong wind that is popular in Jiangdong, and there is no big wave...... Water battles in the river, just like the Colosseum, are fought for troops.

No matter how poor the Wei army's naval division is, it can still delay the pace of Beifu's strong attack on Hedong.

But there is one thing that must be guarded against.

What Chen Qun was thinking in his heart was about to tell Cao Zhen, but Cao Zhen seemed to have thought of it and went to see Chen Qun.

Looking at each other, Cao Zhen said: "I expect that Beifu will send a partial army to cross the river from Shaanxi and Tianjin, and it is necessary to guard against it." ”

The narrow strip north of Shaanxi and Tianjin is a no-man's land that the Wei army voluntarily abandoned, and the north of this narrow strip of east and west is Zhongtiao Mountain.

Nakajo Mountain is conducive to attacking from north to south, which is not conducive to the south, and the south attacking the north is an upward attack.

This is the main reason why the Jin army was able to easily attack the Central Plains by taking the Zhongtiao Mountain in the Spring and Autumn Period, and was able to defend the Central Plains with the difficult and dangerous road of the Zhongtiao Mountain.

It is necessary to divide troops to garrison Zhongtiao Mountain, and also set up beacons in various places along the coast to prevent the Beifu partial army.

Cao Zhen and Chen Qun supplemented the original defense system in Hedong here, and Chen Qun was responsible for the defense of Zhongtiao Mountain, protecting Cao Zhen's flank, so that Cao Zhen could concentrate on defending the Beifu offensive from the direction of Pubanjin and Fenglingdu.

In contrast, Guanzhong Changle Slope, in the military hall.

Tian Xin handled official business as usual, and now that the Han army and the Wei army had been mobilized, the Wei army did not dare to take the initiative to attack...... This means that the recuperation of the Wei State has been broken, and this year's autumn harvest has passed, and the impact is not very large.

As long as it drags on until next summer, the national and civilian strength of the Wei army will decline at a rate visible to the naked eye, and the same is true for the Han army.

In the final analysis, neither the Han army, nor the Wei army, nor themselves were ready for a full-scale war.

The ideal time for war is two or three years later, so that you have a more adequate reserve of officials here, and at the same time, the three sides have sufficient supplies...... As long as the front line is won, it can quickly reorganize and surrender the army, advance to the hinterland of the other side, eat the materials stored by the other side, or levy food from the people.

In one fell swoop, the war can be quickly ended.

As a result, it has broken out now, and it can no longer be bridged and fooled.

Therefore, the war cannot be fought according to the expected plan, but must be fought around the annihilation of the opponent's living forces.

As long as the opponent's huge manpower can be eaten at the beginning of the war, the initiative in the war will be completely grasped.

Tian Xin is not in a hurry to deal with official business, now it is a static brake, as long as he drags it out until next year's spring ploughing, Guan Long carries out limited mobilization for war, even if there is no brilliant victory, he can drag the opposite Wei State to death!

He picked up a letter from Jiazhou, in which Jiang Liang strongly expressed his request to recruit troops and participate in the war, the entire four counties of Jiazhou, the county soldiers and Xifu soldiers added up to more than 13,000 people, and the mobile force was nine battalions of Xifu soldiers.

Jiang Liang hoped to recruit mountain people into Xifu and expand to fifteen battalions.

Strengthen the troops, and if there is a change, send troops from Hanzhong and Hanxing counties...... Even if Yizhou has Jiameng Pass, Baishui Pass, and Yangping Pass as barriers, there is also a road leading to Ba County in Hanzhong and Hanxing Counties.

It has a mass base for recruiting mountain people into the army, and allows the mountain people to recuperate and develop on their own...... How can it be organized and develop quickly?

Tian Xin didn't hesitate much, so he approved Jiang Liang's request, and allowed Xifu to set up an iron mill to open the mountain to forge armor and ordnance.

Lifting the restrictions, Xifu can't forge much armor and ordnance at present...... This winter, the steam forging machine will be able to work in Shanglinyuan, giving Xifu permission, and Xifu will not be able to have more productivity than Beifu.

Just drag it out until May next year...... You won.
