At this time, Toyoju Beach was a suitable area for cultivation with fertile and arable land, and an enclave suitable for cultivation outside of the traditional Han land. But this is the Qiantao area north of the Yellow River (Qiantao is a concept in the modern sense), which is actually not within the Ming Dynasty concept of Hetao. Later generations often confused these two geographical concepts, and some people probably thought that the thousands of miles from Yinchuan in Ningxia to Yulin outside the Hetao were blessed land with abundant water and grass.

In fact, this is not the case, the Hetao area of the Ming Dynasty is not suitable for farming, and the suitable for cultivation is actually the Fengzhou Beach outside the outer loop north of the Yellow River, which is also used for river irrigation.

The vicinity of Ordos in the Hetao is rich in water and grass, but due to the lack of precipitation, it is more suitable for grazing, and this neighborhood is the area where the Ming Dynasty trappers often move, that is, the place where Kangxi, a rabbit shooter, shot 300 rabbits a day.

Zhu Houzhao flipped through the old files and said to Liu Jin: "Go and find a map of the Hetao for the palace!" ”

"Yes, Your Highness!" Liu Jin naturally didn't dare to slack off, and hurriedly went to find a map for Zhu Houzhao, because Zhu Houzhao followed Liu Daxia to learn military affairs before, so there was no shortage of maps of Xianyang Palace, so Liu Jin not only found the general map of the current Hetao, but also found the old file maps of the Hongwu and Yongle periods.

Zhu Houzhao glanced at Liu Jin approvingly, and then took out the old file map of the Yongle period, and the first thing Zhu Houzhao found was Daningwei.

Why did Zhu Houzhao look for this Daningwei in Liaodong? Because Daningwei was also abolished in the first year of Yongle, and was later occupied by the Northern Yuan, it was in a very similar situation to the Hetao. What's more, Zhu Houzhao has to consider the whole situation, and it is Dayan Khan who has to deal with it, not just one located in the Hetao fire screen.

Soon Zhu Houzhao found the location of Daningwei and began to compare it with later generations on the map, whose jurisdiction included the northern part of Hebei Province, the southeastern part of the Inner Mongolia Autonomous Region, Liaoning, Jilin, and the northwest of Heilongjiang. The old file records that Daning is outside the Xifeng Pass, the ancient Huizhou land, the east of Liaozuo, the west of Xuanfu, for the giant town. Ninety cities, 80,000 armor, 6,000 leather chariots, and the three guards of Duoyan cavalry are all brave and good at fighting.

Zhu Houzhao stretched out his hand and knocked on the map, if Daningwei is still there, why will the Liaodong Bureau be like this in the future? Yongle abolished Daningwei in the first year, why? Could it be that Zhu Di's military vision is so poor? Zhu Houzhao began to rummage through the old files, and soon Zhu Houzhao found it.

In fact, Daningwei is also a place that cannot be self-sufficient, and has to spend the power of the four inland provinces to supply.

The supply pressure is too great, so Daningwei was abolished, is it really because of this reason? You must know that the Yongle period was not poor, and Emperor Taizong Zhu Di's several northern expeditions cost a lot of money. Soon Zhu Houzhao found the reason, and the old file records that during the first northern expedition in the eighth year of Yongle, he said to Jin Youzi and others: "Destroy this remnant now, but only defend Kaiping, Xinghe, Ningxia, Gansu, Daning, and Liaodong, then the border will never be fine." ”

However, Zhu Di still felt that the withdrawal of the southern guards to concentrate troops to eliminate the Northern Yuan was once and for all, He Fu had asked Zhu Di to restore the East Shengwei, but Zhu Di still did not think so, and only wrote in the reply to He Fu in September of this year: "Er Song wants to establish the East Shengwei, this strategy is very happy, and it must be taken to suppress the captives, set the border guards, and then establish it, it will always be safe." ”

Zhu Di believed that the establishment of the guard was to wait until the Ming army eliminated the remnants of the Yuan forces in Lingbei Province and determined the northern boundary of the Yuan Dynasty, but because Ming Chengzu suddenly died on the way to the Northern Expedition, the guards set up by Emperor Hongwu in Monan had no time to recover.

From these old files, Zhu Houzhao can be seen that Emperor Taizong Zhu Di is very ambitious and confident in himself, he believes that he can destroy the Northern Yuan Dynasty and incorporate the entire southern Mongolia into the Ming Dynasty, and then divide the border and set up a guard, but he failed to succeed, and he died on the way to the last northern expedition.

Sighing softly, Zhu Houzhao smiled bitterly, he found that he was actually the same as Zhu Di thought, in Zhu Houzhao's opinion, only by turning the entire southern Mongolia into the horse grazing land of the Ming Dynasty can the trouble of northern Xinjiang be completely solved. If you put out the fire sieve today, there may be a water sieve tomorrow, can you extinguish it?

You fight, people run, you leave, people are coming back, it's simply endless, as long as the grassland is still there, this problem can't be solved.

Although Daningwei was deserted, but the same was occupied, Jingtai four years, Duoyan Sanwei begged to live in Daning abandoned city, the Ming court did not allow it, ordered to live 200 miles away. After the day was smooth, the land entered the three guards, but it was still occupied by the three guards of Duoyan.

Zhu Houzhao shifted his attention to the Hetao, and if he occupied the Hetao, it would inevitably become a huge burden. Thinking about the current situation in Daming, Zhu Houzhao instantly felt that there was a long way to go, his eyes moved here, Zhu Houzhao's eyes fell on Fengzhou Beach, if he really wanted to occupy it, it was better to occupy Fengzhou Beach, that is, the front set.

However, the front set is a cultivated enclave, far away from the traditional Han land, and does not border, and is separated from Datong Shuozhou, which is the key defense point in the west direction, and there are many problems in military strategy, and if it is stationed for a long time, it is easy to become a lone army. Therefore, although the Ming Dynasty sent troops to attack and burn the city of Fengzhou Tanbansheng, it had no intention of occupying this place.

In fact, the Ming Dynasty could not talk about giving up or not giving up the Hetao, and the Ming generation never actually controlled the Hetao, so how could it be said to give up?

Zhu Houzhao looked through the old files and found that in fact the Hetao area was just a no-man's land that no one cared about in the early Ming Dynasty, and in the early Ming Dynasty, in view of the sparse population of Inner Mongolia in the Hetao after the Yuan Dynasty's forces withdrew north, he directly adopted the policy of expelling the remaining people in the Hetao or moving to the interior.

For this period of history, Zhu Houzhao is still found in the old files, "In four years, the general Tang Hebing attacked Hannaoer, captured the fierce general Huchen Zhenjun Xie Cheng and other people, and entered the interior, and the Hetao was ruins." The few remaining tribes were also moved into the interior, creating no-man's land as a military buffer.

In fact, in the early Ming Dynasty, it was only used as a part of Shanxi's defense system, and as an outpost in the flexible defense system in the early Ming Dynasty, the outpost of the army marching from Shanxi was not set up to defend and control the Hetao. Therefore, the dismissal of Dongshengwei has nothing to do with the Hetao, it is just a strategic adjustment.

At the beginning of the Ming Dynasty, Hongwu and Yongle could not have predicted the changes in civil engineering, nor could they have predicted the trouble of trapping, after all, they were not immortals. Their generation, because the Hetao is a no-man's land, is in fact undefended at all.

It's just that a few years later, when the Tatars were oppressed by the Warat and had to move to the Hetao area to form a trap, the Ming looked back and looked, yo, how did Dongshengwei give up such an important place? How did the Loop get abandoned?

Many people, including the Ming people, like to use the Han and Tang dynasties as an analogy to restore the Hetao, but in fact, with the economic center of gravity moving south, the capital is no longer in Guanzhong but in Beijing.

The strategic threat of the Hetao to the Central Plains is not as great as that of the Han and Tang Dynasties, after all, the Hetao can directly approach the existence of Longyou Guanzhong, and the ruling center of the Ming Dynasty is not in Guanzhong, and there is no motivation like the Han and Tang Dynasties to seize the Hetao. If you want to seize control, the only reason is to map the territory and fight for fame with the people's fat and people's ointment.

Does that mean that the loop is not important? Is the loop bad? No, it's important, and it's good.

However, if you want to reset, you must build a city on the beach of Fengzhou, otherwise the logistical supply will be unsustainable, and it is impossible for the imperial court to spend a lot of money in this place, unless it is profitable. The best location is actually Fengzhou Beach, as long as the city is built in Fengzhou Beach, then the Ming Dynasty is equivalent to actually controlling the entire Hetao.

But to build a city in Fengzhou Beach, it is necessary to solve the problem of defense and lonely city, otherwise this city will definitely be harassed and captured, it is like a piece of fat in front of the Northern Yuan, the better it develops, the fatter it is, the more serious the Northern Yuan's coveting of it, the slightest carelessness is the destruction of the city, and the development of many years will be ruined, and it will even become an important city of the Northern Yuan.

If you want to solve this problem, you can only knock down the entire Monan Mongolia and turn Monan Mongolia into the horse grazing land of the Ming Dynasty, otherwise this threat will always exist.

Zhu Hou looked at the map and fell into deep thought, now he somewhat understands Zhu Di's behavior, this is out of big strategic considerations, if you want the Hetao land, then you can only wipe out the entire Monan Mongolia and completely occupy this place. Zhu Houzhao also understood why Zhu Di was so persistent in the Northern Expedition, from a grand strategic point of view, this was ahead of its time, and it was also very great.

Sweeping his gaze on the map, Zhu Houzhao found that if he wanted to completely occupy Monan Mongolia, the basic strategy was to follow Zhu Di's direction.

The first is the fire sieve entrenched in the Hetao, which must be eliminated, and they cannot be allowed to occupy it here, turn this place back into a no-man's land, make it a strategic buffer zone, and then start in the east, consolidate Liaodong, send troops to attack Duoyanwei, take back Daning City occupied by Duoyan Sanwei, and then continue to advance to the depths of the grassland with Daning City as the foundation.

Lay down the Fengzhou Beach in the west, and then build a city on the Fengzhou Beach, at that time, the Ming Dynasty can send troops from the Fengzhou Beach to fight to the east, or from Liaodong and Daning to the west, and once the war starts, it must not stop, and it must always be defeated throughout Monan Mongolia, otherwise it will be withdrawn from the Fengzhou Beach again, which is the war of annihilation that cannot be stopped at the beginning.

The later Qing Dynasty's westward expedition carried out this strategy, and at the same time, it was able to attack from along the Great Wall to be beaten, so that the entire Monan Mongolia could be completely bagged.

Stretched out his hand and compared it from east to west on the map, Zhu Houzhao smiled bitterly, and sat on the chair a little weakly, relying on the current national strength of the Ming Dynasty, relying on the current financial strength of the Ming Dynasty, and relying on the current military strength of the Ming Dynasty, this idea could not be completed at all. It is meaningless to simply fight the Hetao and Daning, and it is useless except to increase the financial burden of the imperial court.

Only when you take Monan Mongolia can you move the Great Wall defense line forward, otherwise the Great Wall defense line needs a lot of consumption, and it still takes a lot of consumption to maintain Hetao and Daning, this consumption is too great, especially under this transportation condition, it would be good if there was a train, Zhu Houzhao couldn't help but sigh.
