"Let the Bohai Sea lead the people of Hanoi to Mengjin, and the sour jujube generals will guard Chenggao, according to Aocang, Saiyuyuan, Taigu, and all control their risks."

This is the strategy of Wei Wu Cao Cao in the "Chronicles of the Three Kingdoms" when he crusaded against Dong Zhuo in the Shandong Princes' Alliance, regardless of whether this strategy is famous or not, whether it is feasible or not, but at least it points out the pass fortresses around Luoyang.

Luoyang has eight passes in ancient times, and in addition to Cao Cao's words, there are also Yique and Guangcheng passes in the south. That's because at that time, these two passes had been occupied by Sun Jian, who was then the Taishou of Changsha, and Sun Jian killed Dong Zhuo's general Huaxiong at Guangcheng Pass.

In addition, there is also the Hangu Pass between the west of Luoyang and Guanzhong, which constitutes an important pass around the entire Heluo area.

Since the Huainan Army used troops at the beginning of the year, its greatest strategic intention was to seize Heluo. As for the wars between Hebei such as Liyang and Yecheng, the main purpose was also to eliminate the interference from Hebei.

In fact, at the beginning of the war, Shen Zhezi's plan was able to severely damage Shi Kan and make him unable to look south, which can be regarded as the completion of the strategic goal at this stage. But Shi Kan couldn't help fighting, and Shi Hu didn't want to miss the opportunity brought to him by the Huainan Army going north, so it caused the current situation.

Dong Zhuo faced during Cao Cao's period. and the peach leopard who is currently entrenched in Heluo, it is not an equal opponent at all. Moreover, the disputes in the late Eastern Han Dynasty were completely different from the current war environment, which caused a completely different fighting style and rhythm.

In the last years of the Eastern Han Dynasty, although the princes rose up and fought strongly, the productive forces were not so seriously destroyed and destroyed by later generations at the beginning, so there was no lack of long-term confrontation, including large-scale military battles, which was especially obvious when the Three Kingdoms were juxtaposed. In the areas bordering each other, the three countries have maintained a tense confrontation almost constantly, and the war is almost like a series of catastrophes.

The Three Kingdoms were unified in the Jin Dynasty, and the short rule of Taikang was not enough to restore the vitality of the north and the south. As a result, no matter which side of the North and the South is in charge, they do not have enough savings and strength to carry out a long-term confrontation and attrition.

Therefore, the pace of war in this period is much faster, with many field battles, tackling fortified positions, and quick battles, and it is difficult for every war to last too long. In the final analysis, it lies in one word, that is, poverty, if a war drags on for too long, although it is victorious, it is defeated.

Of course, although the basis of war is different, the basic principles are still the same. The focus of attacking and defending Luoyang is still in the surrounding dangers, and as for the gains and losses of Luoyang itself, it is not very important.

In the early years, the two Zhao fought each other, and there were several large-scale battles around Luoyang, and the core of their battle victory and defeat was the use of the surrounding passes.

Leaving aside the Hangu Pass in the west, Luoyang is slightly more open to the north, but the Yellow River runs through it, and on the north bank of the Yellow River there is a mountain as a barrier, and further east it reaches Hanoi County in the Hebei Plain. The most important pass in this direction is Mongjin, and the small Pingjin is located in the middle of the river.

Luoyang passes through Yanshi to the east, and connects with Xingyang through a narrow passage between the Yellow River and Songshan, and on this passage is the famous Chenggao and Tiger Prison Pass. Tiger Prison Pass is a connection point between the hilly mountains of western Henan and the vast plains in the east, when the Chu and Han dynasties fought for hegemony, it was still difficult to cross the thunder pond one step, which shows its danger.

The two passes of Yuyuan and Taigu that Cao Cao said are located in the southeast and south of Luoyang. Among them, the Yuyuan Pass is more important, this pass is located in the canyon between the Shao Room and the Tai Room Mountain in the Song Mountain, from which you can go directly to the hinterland of central Henan, go straight to Xuchang, choke the Ying Water and raft to impact the Huai Shui.

The so-called Yongjia Rebellion is the Han Zhao Liu Cong's capture of Luoyang as the starting point, when Liu Cong besieged Luoyang, his son Liu Cang came out of the Yuyuan Pass, and Ru, Ying, Chen, and Liang were trampled on.

Just south of Luoyang is Yique, later called Longmen. The so-called Yique, is the Yishui waterway gate, as long as you rush through the pass here, you can go straight to Luoyang, is the well-deserved south gate on the Heluo Plain.

Since the Huainan Army had already determined its strategic intention to recover Heluo early on, it was naturally planning from the beginning.

Since last year, the Huainan army has sent troops to sweep the Haoqiang Kingdom entrenched in Nanyang, and completely cleared out this place, so that Sima Wuji, the king of Chen, can lead his troops north into the town, until it reaches Wancheng.

The men and horses of the King of Qian were only between three or four thousand, so before the Huainan army marched north, Shen Zhezi sent Xie Yi and Shen Yun to lead three thousand Huainan cavalry to help, plus the three thousand troops from Xiangcheng and westward to Luyang, a total of 10,000 troops blocked the passage of the Taobao army to the south.

And Xuchang, which is referred to at the exit of Yuyuan Pass in the southeast, has simply become the base camp of the Huainan army, where thousands of soldiers are assembled, even if it is not aimed at Heluo, it is enough to make Taobao's troops frightened and dare not go out lightly.

Of course, for a certain period of time, there was a defensive hole here in Xuchang, that is, when Shen Zhezi's lone army was on the riverside in the north, and the armies in the south were urgently dispatched to the north to help.

Xuchang is the base camp of the Huainan Army's northward soldiers and material assembly, and during that period of time, if the peach leopard dares to gather men and horses to bravely go out of the Yuyuan Pass and attack Xuchang with sharp cavalry, it may not be impossible to succeed. Because Xuchang during that period of time was like a nest in the Battle of Guandu.

It's a pity that none of Shen Zhezi's subordinates appeared Xu You. Moreover, at that time, the Huainan army was surging and approaching Hebei, and it was not the peach leopard as the main opponent. At that time, the soldiers under Taobao were still keen to rob the merchants who traveled to and from Runan, and they were not aware of this rare fighter.

The opportunity was fleeting, and soon King Qian led his troops north to attack Yique, taking the enemy by surprise. The southern portal was directly threatened, and Cheng Gao was always under great pressure, even if the peach leopard sensed the weakening of Xuchang, he didn't have the time and strength to make any more moves at that time.

With the end of the first battle of Liyang, Mao Bao led his troops down from the chasm, and while returning to Xuchang, he also had to advance to the Yuyuan Pass to completely make up for this loophole in the Huainan Army.

Therefore, the current situation is that in these dangerous passes around Luoyang, the Huainan Army has blocked the two most important gateway passages of Yique and Chenggao. The Yuyuan Pass side has also reserved enough troops, and even if it cannot successfully attack Heluo, at least it can block the enemy army in Heluo and ensure the safety of the hinterland of Yuzhou.

In the Xingyang camp, the generals of Xuzhou participated in the official military meeting of the Huainan Governor's Mansion for the first time. When the Huainan Army had arrangements for Luoyang in front of them, these generals from Xuzhou couldn't help but be surprised.

To be honest, people will inevitably have the desire to win, especially the martial arts in this regard. Xuzhou was originally one of the most important military towns in Jiangbei, and even if these generals led the leaders of the army, they were all war-tested generals, and the soldiers were all elite, at least the combat effectiveness of each person's descendants was fully guaranteed.

However, since the Huaishang War a few years ago, Huainan has sprung up, and it has steadily overwhelmed the Xuzhou Army in terms of combat results and wind evaluation. Although these military leaders have their own needs. Most of them maintain a good relationship with Huainan, but they have some resentment about this phenomenon.

Even some Xuzhou army leaders, who explicitly or implicitly prepared to defect to Shen Zhezi, were more out of consideration for the future, rather than firmly believing that the Huainan army would defeat the Xuzhou army. In their view, the combat effectiveness of the Huainan Army is more based on the use of strong weapons, and once the two sides maintain the same level, the Huainan Army will never be the opponent of the Xuzhou Army.

It is true that the battle of Liyang brought them a lot of frustration, although the battle ended with the collapse of the Shikan army itself, but the problem is that it is much more difficult to be able to oppress the enemy army with little resistance and defeat before the battle.

All the generals in Xuzhou are generals of the Rong Brigade for a long time, so naturally they will not criticize the Huainan Army in this regard. In particular, the Huainan First Brigade dared to go deep into the north and take Yecheng directly, which made them have to give the Huainan army a serious face, and the other party was at least an elite soldier equal to themselves.

After seeing the arrangements made by the Huainan Army in order to recover Heluo, the generals of Xuzhou finally realized why the Huainan Army was able to make many great achievements, even if the combat effectiveness of the two sides was equal, but the Xuzhou Army was indeed not the opponent of the Huainan Army.

At the very least, the Huainan Army gathered tens of thousands of troops from the beginning of March to block the southern gate of Heluo. Even if the main combat area was still in the direction of Hebei during this period, this force always maintained a state of assembly and preparation, which alone was beyond the reach of the Xuzhou Army.

It's not such a great strategy to make arrangements in advance and attack and defend in a targeted manner, and any general with normal tactical strategy can make this decision. The problem is that it is much more difficult to implement the decision.

The generals of Xuzhou have been on the side for a long time, but from their memory, there are few large-scale mobilization battles, and they have lasted so long. Most of the battles in Xuzhou are in a state of stress, taking the initiative to attack when they are strong, and passively defending when they are weak.

Therefore, when Taishan County suddenly appeared uncertain, there was no response plan itself, and no army took the initiative to attack and settle the chaos. In the end, it was Shen Mu, an outsider, who took the lead, and the rest of the armies followed suit.

Similar to the gathering of the people of Nanyang for half a year, don't even think about it, more than half a year will not be an inch of work and consume a lot of materials, even if the Assassin Mansion is willing to take the initiative to bear this payment, the generals may not be happy. Seeing others hunting, they retreated, and it was better to simply disband the tribe and go home to farm if they had this time.

Therefore, with the organizational model of the Xuzhou Army, in the face of the huge goal of Heluo, it is basically impossible to arrange it months in advance. Their battle mode is that before the battle, the assassin Shi came forward to coordinate all parties, agreed to advance together, and then fought concurrently in all directions, and fought violently.

In this way, the enemy army has already been prepared and made targeted arrangements. Once the war is not going as well as it should be, or finding that one side is fighting more difficult, the soldiers of that side will be dissatisfied, or ask for more compensation, or turn to the side to ensure their own interests.

If you can't take it and have to go back, the process will have to be repeated.
