Xiangshan lies on the north bank of the Yu River, faces each other across the river with the mountain, but the mountain is much more precipitous than the mountain, the main peak of the east and west is more than six or seven hundred zhang high, its mountain stretches more than three hundred miles from east to west, but the depth of the north and south is only twenty or thirty miles, the mountain is very narrow and long, so it is also called the middle mountain.

The Yu River goes south from the west foot of Zhongtiao Mountain, joins Jingwei and other streams originating from the Loess Plateau, turns east and flows from the southern foot of Zhongtiao Mountain, and flows through the Fenshui of Taiyuan Prefecture, Fenzhou, Jinzhou and Puzhou, and joins the Yu River at the northwest foot of Zhongtiao Mountain. There is a branch vein Wangwu Mountain to the east of Zhongtiao Mountain, and at this time, Zhao Mengji led more than 30,000 soldiers and horses to guard Mengzhou, which is located at the east foot of Wangwu Mountain.

As far as its strategic position is concerned, Xiangshan can be said to be the key place overlooking the south of Jin, the east of Guanyong, and the south of the river.

There are more than 90 counties in 18 prefectures in Hedong Ancient County, and the prefectures of Fen, Jin, and Pu in the middle and lower reaches of the Fenshui River account for nearly one-third of Hedong's population and cultivated land, and Taiyuan Prefecture in the upper reaches of Fenshui accounts for half of Hedong's population and cultivated land.

There is another point that military strategists and strategists have never been able to ignore.

The pond salt, which has been developed on a large scale since the pre-Qin period, is produced in the Hedong Salt Pond at the northern foot of Xiangshan Mountain, which is also the most famous saltwater lake in the Central Plains.

For hundreds of years, the salt produced by Hedong Salt Pond has been sold to Guanyong, Hehuai, Hedong and other places.

In the early years of the previous dynasty, the salt farmers of the salt pond had already adopted the salt pan drying method to make salt, and the annual output of millions of stone pond salt was produced at the peak, and the system of selling was implemented after the middle of the previous dynasty, and this salt lake was about 60 miles long from east to west, and could transport millions of salt profits to the center every year.

When the Jin State occupied the salt pond, the salt profits once accounted for one-third of its central income.

In addition to the Fenshui River valley at the northern foot of Zhongtiao Mountain, which was easy to directly threaten the core area of Jin rule, another reason was to reduce or even destroy the salt profits that the Jin State could obtain from the salt pond in Hedong through war.

If the Great Liang soldiers and horses can be inserted into Zhongtiao Mountain to gain a foothold, the effect on the enemy army will be too great, but the problem is that Liang Jin has been fighting around Zhongtiao Mountain for thirty or forty years since before the founding of the country, and countless fortresses have been built in the mountain, which are all in the hands of the enemy army at this time.

In addition, because Zhongtiao Mountain is extremely long and narrow, it is backed by the Fen River valley in the north, which means that it is extremely easy for the soldiers and horses stationed in Hejin to reinforce the defense in the mountain.

If Han Qian had sent elites from Bishan to cross the Yu River at this time, he would not be able to carry heavy weapons to attack these fortifications, the foothold on the north bank of the Yu River and the area for soldiers and horses to deploy were too narrow, and if he attacked strongly, he was destined to suffer heavy casualties.

And even if you pay heavy sacrifices to defend one or two fortifications, it will be difficult to resist the enemy's more dominant counterattack from the north, and it will be difficult to hold the fortifications in the mountains.

Otherwise, in the past thirty or forty years, the Liang army would not have needed to bypass Xiangshan every time, cross the Yu River from the north of Huazhou, and directly attack Jinzhou and Puzhou north of Xiangshan.

Yin Pengzheng felt that Han Qian's method was difficult to do, and looked down at the sand table that the mountains and rivers such as Yuhe, Songshan, Bishan and Xiangshan had been stacked very realistically, and he could clearly see the distribution of the blockade in Xiangshan.

Yin Peng had just arrived, and he was not familiar with many situations, so he patiently listened to Guo Qi, Feng Xuan, Wen Bo, Chen Kun and others standing in front of the sand table to discuss the next battle plan.

At present, the soldiers and horses of the enemy army stationed in the Jin, Pu and other Hejin areas and Zhongtiao Mountain are Tian Weiye's headquarters and more than 10,000 elite Mengwu cavalry.

Tian Weiye was originally the assassin of Luzhou in Jin, and under the strong attack of the Liang army led by Zhu Yu, he held the city of Luzhou for nearly a year, causing Zhu Yu to be finally copied by Zhu Rang and Wang Yuankui and the Muguls, resulting in a series of fiascos.

Luzhou food exhausted, Tian Weiye dedicated the city to the Mengwu people, because his wife and children were slaughtered by the king of Jin Lu, led the troops to attack Taiyuan City the most fierce, and then as the vanguard army led the troops to attack Guanzhong, the edge was sharp, and finally he did not hesitate to kill and die to capture Yongzhou City.

At first, Mengwu wanted to use Tian Weiye to continue to attack Hanzhong in the south, but after Han Qianchan succeeded to the position of the lord of the Great Liang State, Wusu Dashi and Xiao Yiqing adjusted their strategies, so that Wang Yuankui and Wang Xiaoxian guarded the Yongnan region, and transferred Tian Weiye, who had the most dazzling military achievements, to Hejin and served as the envoy of Hejin Jiedu.

Obviously, Wu Su Dashi and Xiao Yiqing also knew completely early on that the Mongolian army would not be able to successfully capture the Heluo area, and the strategic position of Xiangshan in the Liangmeng battle situation would be completely highlighted.

However, Han Qian didn't care how strong Tian Weiye and his subordinates were, and no matter how elite the 10,000 Mongolian cavalry stationed in Fenshui Nan and controlled by Tian Weiye were, and how brave and good their generals were in fighting with Haishan.

Since the wars in Heluo and Jinnan in the middle and late stages of the former dynasty became increasingly fierce, there have been as many as forty or fifty fortresses built in Xiangshan in the past hundred years, but these small and medium-sized fortresses are mainly built according to the wide valley and relatively gentle slopes, but it is impossible to fill every peak and every stream and valley of Xiangshan Mountain, which is more than 330 miles long, without leaving a single gap.

Han Qian didn't want the Liang army and horses, at this time, he would attack the enemy's strong defenses in Xiangshan, he wanted to scatter the soldiers and horses, and enter Xiangshan with a sentry team or even a smaller group of soldiers and horses, looking for a foothold in the gap between the enemy's defenses.

Xiangshan is more than 300 miles long from east to west, and the widest part of the north and south is only 30 miles.

Such terrain characteristics mean that once a foothold is obtained in Xiangshan, it is much easier to threaten and harass the enemy's production and garrison on the north side of Xiangshan and on the south bank of the Fenshui River Valley.

Drill into Xiangshan, the follow-up will continue to cross the Yu River, transport materials and craftsmen to the other side, build a small fortress according to the dangerous valley peak, and form a mixed situation with the enemy army in Xiangkou, so as to advance the follow-up tug-of-war and stalemate from the south bank of the mountain and the Hugao Pass line to the north bank of Xiangshan.

Listening to the battle plan initially drawn up by Han Qian and the generals of the Military Intelligence Staff Office, you discussed word by word, and improved more details, Yin Peng suddenly remembered the early Chishan Army's reversal of the Jinling situation in Maoshan and Fuyu Mountain, as well as the many examples of the Tangyi Army recovering Huaixi step by step over the years, and thought of Han Qian's most advantageous combat method over the years, isn't it a small group of soldiers and horses scattered into the mountains to fight between them?

This is undoubtedly the best strategic and tactical choice for Daliang to use a small number of elite soldiers and horses to pin, exhaust and consume a large number of enemy troops under the situation that Daliang is in great need of rest and recuperation.

Yin Peng couldn't imagine that the enemy generals Tian Weiye and He Haishan could have any better means besides strengthening the anti-blockade construction north of Zhongtiao Mountain.

Since the period of the Chishan Army, the soldiers and horses led by Han Qian have been good at mountain warfare, and even better at small groups of soldiers and horses to persist in long-term combat in complex terrain, which is directly and closely related to Han Qian's large-scale absorption of cottage forces in his early years, gaining a foothold in Xuzhou, being very good at managing mountainous areas, and continuing to train grassroots military attachés on a large scale over the years.

Like Chen Jingzhou's son Chen Yuanchen, as a disciple of the cottage family in the early years, he arrived in Luoyang more than a month earlier than them, and at this time he went directly to Wen Bo to join the army, which can be said to be the advantage of the Liang soldiers and horses in this regard.

At present, the strength of the Great Liang is not strong enough, the cavalry establishment is limited, and the ability to maneuver in a roundabout way is weak, so it is natural to avoid fighting with the enemy in an open area, but dispersing into complex mountain operations can not only give full play to their own advantages, but also make the advantages of the cavalry of the Mengwu unable to give full play......

The specific battle plan is that Wen Bo will lead Li Mo, Xue Chuan and other generals to carry out the operation according to Pishan, Chen Kun will lead the naval brigade and the boat bridge to cooperate in the operation at the Tiger Prison Pass and Lin Jiang; In the later stage, the newly formed infantry brigade and garrison brigade of the Jingzhao Garrison will enter Xiangshan to fight in the form of a round battle.

After discussing the matter, Wang Jun rushed over from the medical camp, and was very happy to see Yin Peng, and asked a lot of questions about the situation of the Wang family and the Yin family after crossing the river during the banquet.

Lu Ze was directly assigned to the First Guards Brigade, and under Huo Li, he served as the deputy commander of the brigade -- at present, the Military Intelligence Staff Office has further improved the new battalion establishment, and the highest-ranking general in the army who directly holds the command power has been designated as the commander of the town (army), and a new brigade commander has also been set up, as a formal military attache and general to command the brigade-level military units to fight, and the status of the military commander in the Liang army has been relatively lowered.

Yin Peng, as the Lang official of the Military Intelligence Staff, is actually still a military attaché, and Guo Ke, Wang Zhe, Feng Yi and others stayed in Han Qian to participate in the military aircraft - Huo Xiao, as the first batch of Wang Jun's sons to join the Tangyi Army, served as the commander of Songyang County before the previous year, responsible for the widening of the Songnan plank road, and the Songnan plank road widening project has been completed, and he completed his duties very well, and he was transferred to Luoyang two days earlier than Yin Peng, and his new position was to serve as the Luoyang County Commander under Yin Zhouyi of Jingzhao Mansion.

"Wusu Dashi has issued a decree in Taiyuan, the Mengwu tribes have begun to move south, the first people have entered the territory of Shuozhou, and the state and county governments in Hejin, Guanzhong, Shangdang and other places have begun to occupy the fields and houses to prepare for the southward migration of the Mengwu tribes," Han Qian personally introduced more of the situation to Yin Peng, who had just arrived in Luoyang, "and according to the scouts who went deep into the area north of Yunzhou to scout the military situation, this time the southward migration of the Mengwu people mainly involved the tribes belonging to the thirteen-winged cavalry who had followed Wusu Dashi to conquer Yanyun, Bohai, Heshuo, and Hedong in recent years. The population is expected to exceed 600,000, almost half of the core Mughal tribe. At present, in addition to the 50,000 cavalry on the thirteenth wing that Wusu Dashi has led into the Central Plains, it is estimated that among the 500,000 southward migrants, there are almost 50,000 cavalry who are good at cavalry and archery for Wusu Dashi to recruit, which will be used by Wusu Dashi to strengthen the military force of Hedong, Guanzhong, Heshuo and other prefectures and counties......"

The more than 100,000 Han troops that Wusu Dashi has collected in Yanyun and Bohai over the years, plus Wang Yuankui, Tian Weiye, Zhao Mengji, Wang Xiaoxian and the Eastern Liang Army, are already strong enough, Yin Peng heard at this time that with the large-scale southward migration of the Mengwu tribe in the autumn and winter of this year, there will be 50,000 elite cavalry under Wusu Dashi who can be recruited, and he feels a headache for Han Qian when he thinks about it.

Even if Wusu Dashi used these soldiers and horses to strengthen the rule of Hedong, Guanzhong, Heshuo and other prefectures and counties, it could replace the Yanyun and Bohai Han armies that had been deployed in these prefectures and counties before, and further strengthen the military blockade of Heluo.

At this time, it seems that it is of great significance to launch Xiangshan interspersed and tug-of-war operations in this winter and autumn, but at the same time, it also means that the early stages of the various departments will take turns to enter Xiangshan to carry out tug-of-war operations, which will become more cruel and bloody.

"This is bad news, but also good news," Han Qian commented on this matter rather blandly, and said, "Although the decree issued by Wusu Dashi and Xiao Yiqing is based on the fact that the former Jin State did not come to settle the southward migration tribes in Zhuzhou County, whether Wusu Dashi wants to use the southward migration tribes to actually rule these regions, or maintain a high proportion of troops drawn from one tent, it is destined that these tribes will forcibly occupy a large amount of land with abundant water and grass when they go south, and they are destined to force a large number of people to enslave them - when the soldiers of the various tribes are fighting, It is also necessary to pay attention to distinguishing between the enemy forces which we can divide, instigate, or even fight for and liaise with, and which ones need to be resolutely attacked and eliminated......"
