In the morning, Xiaoxue, in a classroom in a military academy, students surrounded the long sand table and studied strategies.

The sand table shows the situation of the Taishang Mountains, including various main mountain passes, together with the main passes, cities, and terrain along the way, which are very detailed.

Today's research topic is "The Battle of Hedong".

The Hedong region, as the name suggests, is the "region east of the Yellow River", and is located on the east side of the north-south section of the middle reaches of the Yellow River.

It is generally the boundary of Hedong County during the Han Dynasty, and is across the river from the Guanzhong area, which is the Shanxi area in later generations.

Jinyang, the key area of ​​Hedong region, has been a must-fight for military strategists since ancient times.

Now, Qi State only has Hedong region and the northern Dai and Shuo land. How to completely eliminate it and take down Jinyang is the first problem that Chu State needs to solve next.

But it is a bit troublesome due to geographical factors.

More than a year after the Battle of Hebei ended, and the imperial court initially controlled this rich and vast area, but to attack the Hedong area west of Hebei, it was necessary to cross the Taihang Mountains.

The Taihang Mountains are north-south, like a high wall, separating Hedong and Hebei. If the army wants to cross the Taihang Mountains, they can only walk through several mountain passes.

These mountain passes have existed for many years and are ready-made roads, but due to terrain, the brigades of troops cannot be used during combat.

Now, the Qi army has set up many obstacles in various mountain passes, and it is not easy to break through. If the Chu army is blocked by one of them, it is impossible to advance or retreat, and it is easy to be cut off by others.

Even if one or several mountain passes finally breaks through and enters the Hedong area, the subsequent transportation of grain and grass by the army is quite expensive, because it can only rely on manpower and animal power to transport grain and grass through mountain roads.

The Qi army retreating to Hedong had no choice but to retreat. Jinyang was also the place where the Gao family's dominance was gathered. If the Chu army who came over the mountain suddenly stood under the strong city, crossing the food road of the Taihang Mountains, it was a huge burden.

Moreover, once the Battle of Hedong begins, Zhou, which had already shaken hands with Qi, would not be on the sidelines and would definitely support Qi and go to war with Chu.

The battlefield at that time may not be limited to Hedong.

The Battle of Hedong is related to the situation in the world and will inevitably become a decisive battle between the Three Kingdoms.

So, how should we fight the Hedong Battle?

Although the students of the military academy do not have the right to make decisions, they do not prevent them from putting themselves in their shoes to consider this issue. Even if they are just talking about it on paper, they have to talk about it.

Li Li, who came to the military academy to inspect, listened to the students' discussions with the accompanying generals.

Because of the preparations, the students' speeches were more concise, and the strategies they formulated were basically focused on fighting between the Chu army, Qi and Zhou coalition forces.

Therefore, the overall strategy is not much different, mainly to surround Hedong to attack the Hedong area of ​​Qi, and actually deal with the main force of the Zhou army.

The reason is similar to breaking the city and fighting aid first. The Qi army was already seriously injured and dared not come out in guarding Hedong, just like a city guard.

The reinforcements that can fight in the field are naturally the Zhou army. As long as the Chu army defeats the Zhou army and the Qi army does not rescue, it will naturally be easy to deal with.

When it comes to implementation, the difference in details lies in where is the preset battlefield for the main force of the Zhou army.

Plan 1: The preset battlefield is in the Luozhou area of ​​Zhouguo (near Luoyang).

First, he feinted the attack on Hedong and forced Qi to ask for help from Zhou. In this way, some Zhou troops would enter the Bingzhou area to "coordinate defense".

This move will inevitably lead to the outbreak of war between Chu and Zhou, and the opponent's Luozhou garrison is unlikely to take the initiative to attack, so the Chu army will take the initiative to attack.

In Luozhou and Shanzhou to the west, they fought decisive battles with the Zhou army one after another, consuming their troops and making them unable to reinforce Qi.

Plan 2: The preset battlefield is located in Bingzhou, Hedong.

The main force of the official army crossed the Taihang Mountains, attacked the Bingzhou area, besieged Jinyang, and waited for the Zhou army to come and fight to the decisive battle with him.

Defeat foreign players, take Jinyang, occupy all the land in Hedong, and then head north to replace the Shuo area.

Zhou Guo would not watch it, and would mobilize a large army to counterattack. Then, it would be enough to fight again.

In addition, there are different ideas for solutions:

The main force of the official army gathered a large number of horses and left Juyongguan, from the Northern Yanzhou that had been captured, and went around to Hengzhou, Qi State.

Invading Dai and Shuo areas, they attacked Jinyang from north to south, instead of spanning the Taihang Mountains from the east.

The official army confronted the Qi and Zhou dynasties in the Bingzhou area, and then retreated on the same route.

In this way, will the Zhou army entering Bingzhou area have a "reverse guest"?

This plan is interesting. The purpose is not to fight decisively, but to provoke internal strife between Zhou and Qi. Although the two countries may not turn against each other, there are still chances.

If the first time doesn't work, then do it again. The third time, just like the allusion "The King You of Zhou played with the princes in the beacon fire", it may not be possible to create opportunities from this.

Of course, if this plan is implemented, there are risks:

Going north to Dai, Shuo, and then heading south to harass Bingzhou. The flanks and even the rear paths will be exposed to the direction of the grassland. Once the rear paths are captured by the Turks, it will be bad.

However, considering that the Turks quickly frightened away when they attacked the northwest border of Youzhou last year, perhaps, in the next few years, the other party will be less likely to pay attention to the situation in Dai, Shuo and Hengzhou, and their reactions will be slower.

Li Li was thinking about this plan and found many hidden dangers.

The marching route of this plan is actually to walk upstream along the water.

?Shui, recorded in "Shui Jingzhu", describes its direction according to current geographical terms. It originates from Shuozhou area, then flows northwest, passes through the southern border of Hengzhou, and enters northern Yanzhou.

Northern Yanzhou is west of Juyongguan, northwest foot of Taihang Mountain/Yanshan Mountain Range. After the water passes through Huairong, the capital of Northern Yanzhou, and turns to the southeast.

Cross the mountains, enter the northwest border of Youzhou, flow to the southeast, pass the southwest of Jicheng, continue to the southeast, and finally pour into the sea.

Therefore, for this plan to enter the Bingzhou area from the north, the marching route is to walk upstream along the water river channel, and there are ready-made roads along the way.

However, the water often gets heavy water during the rainy season, and the more it reaches the downstream, the more obvious it becomes. After a severe rain, the river surface can become wider instantly.

The wider river surface may not necessarily flood the road, but many narrow and long sections of roads may not be able to operate.

Moreover, the direction of traveling from Northern Yanzhou is the same as the direction of the Great Wall in the North (on the inside of the Great Wall), so the Chu army will enjoy the treatment of "uninterrupted beacon warning" by the Qi army along the way.

A surprise attack is definitely not possible. As the students analyzed, along the way, the flanks are easily threatened, and the attack may be the Turks or the Great Wall garrison of Qi.

Once the road ahead is blocked, the army hanging out will be cut off at all times, which will have a great impact on the mentality of the soldiers.

However, the shock to Qi State was not small.

The opponent lost Hebei, and the subsequent counterattack also suffered heavy casualties. The generals lost a lot, and there were probably not many legions that could fight in the field.

The most important thing is that the emperor is incompetent and there is a group of villains around him. At the critical moment of survival of the family and country, this young emperor does not have the ability to turn the tide at all.

Then, when the Chu army suddenly rushed over from the north, the monarch and ministers of Qi responded, afraid that it was not a flaw that should not have been made, and they might have actually made a flaw.

Once the Zhou army is asked to "assist the war" and beware of each other, it may lead to "sparks".

According to later generations, Chu Jun's strategy was like a thug who came to the store to collect protection fees, poured gasoline on his body, held a lighter (you can't light the fire), and said that today, I would either take the money away or you would help me collect the body.

The one who compares is who is bold.

Li Li looked at the sand table again, looked at Dai and Shuo area, and fell into deep thought.
