After some discussion, the tactics of attacking instead of defending were decided to defuse the attack that Meng Yuan was about to launch, and the generals began to discuss the use of troops, the division of the battle line, and how the various armies coordinated. However, Zhao Yu found that the generals of Jiang Cheng and the various armies belonging to the Huguang Theater were a little interested, and their expressions were silent, and he understood after a little thought that the battle was mainly carried out along the lower reaches of the Yangtze River, but all the armies stationed in Huguang were stationed in the middle and upper reaches and the Huguang area, and no matter how lively the battle was, they only had to watch the show. And in the army, they must have military merits in order to be promoted and rewarded, but they have no chance, so they are naturally not interested.

"Jiang Dushuai, now Dali and some areas of South Guangxi Road and west of Jiangling are still in the hands of the enemy, and they are ultimately our henchmen, how to eliminate them, you have a good plan?" Zhao Hao thought of this section again, so he asked out loud.

"Your Majesty, the minister thinks that in order to eliminate the threat of Meng Yuan to my flank, only by capturing Dali and Sichuan Shu can we protect the peace in Jiangnan!" Jiang Cheng thought for a moment.

"Jiang Dushuai has a case for the southwest to enterprising?" Zhao Hao then asked.

"Your Majesty, the minister has discussed with the generals how to improve the current passive defense posture, and all the generals think that although our defense direction is in the north of the river, the southwest is a problem for the henchmen as Your Majesty said, and we will have to garrison heavy troops to prepare for war one day later. However, Meng Yuan occupies the upper reaches, condescendingly, occupies the geographical advantage first, and always takes advantage of the downward attack. Once Eju is lost, the enemy army will be able to move south and reach the Gyeonggi region. Jiang Cheng said.

"Well, what Jiang Dushuai said is good, and this is also what I am worried about. However, Sichuan and Shu have gone through wars, and the people have been slaughtered, and it is no longer the rich country of abundance in the past, if our army recovers Sichuan and Shu, the local wealth can not be self-sufficient, and it will be a great burden to rely on Jiangnan transportation; Enterprising Dali and recovering Guangnan, there is a slang settlement, where we do not know the situation, geography is unknown, and rebellion is impermanent, which will also involve our great energy. Zhao Yu nodded and expressed his worries.

"Your Majesty is very worried. The minister also thought of a solution, and wanted to make a suggestion to His Majesty, but felt that there were still shortcomings. Jiang Cheng hesitated.

"Jiang Dushuai but it doesn't hurt to say it, let's refer to it together!" Zhao Yu said with joy on his face.

"Your Majesty, the minister thinks that you can take Xichuan first, and then take Xiangxi and Dali!" Jiang Cheng said.

"I want to hear about it!" Zhao Hao took a sip of tea and said.

"As Your Majesty said, Shu is now sparsely populated and has become a barren land, and from the current situation, it is not a strategic place, but Xichuan is choking the upper reaches of the Yangtze River, as long as Xichuan is stable, the downstream will be worry-free......" Jiang Cheng pondered for a moment and said his thoughts.

When the Mongols invaded Shu, the Mongolian cavalry was good at attacking the city and plundering the land, using many tactics such as encirclement, fire attack, artillery attack, water attack, tunnel, the traditional city of the Great Song Dynasty was often built on the platform on the bank of the river, and the city was an endless open area, the Mongolian cavalry "came like the sky falling, went like lightning", and the Song infantry broke up like a tide once it was impacted. There was not much resistance in front of the Mongol cavalry.

Later, Yu Jue, a famous anti-Mongolian general, served as the envoy of Sichuan pacification and presided over the Sichuan defense line. Yu Yu was the former deputy envoy of the Huaidong system, and the people in the two Huai areas often defended themselves in the middle of the mountain, called "Shanshui Village". In view of the uncertain movement of the Mongol cavalry and the fact that there was no danger to defend in the western Sichuan Plain, Yu Jue was inspired by the Shanshui Village to move the city to the mountains and establish a mountain city defense system.

Most of the mountain cities of the Song Dynasty are located on the cliffs of the mountains and rivers, although the average altitude is only three or five hundred meters, but the cliffs are surrounded, far more dangerous than the artificial city walls, and some places can even rely on the natural danger without building the city. The top of the "Fangshan" mountain is flat, ranging from hundreds of ten acres to dozens of miles in the circumference, there is land to cultivate, there is forest to use, there is water to drink, it is suitable for the army to be stationed for a long time, and the people who fled also come to the mountain city to cultivate and live, and provide the necessary grain and grass for the army.

Yu Yu led the Sichuan military and civilians to establish a total of more than 80 mountain cities, these mountain cities are held at the confluence of the two rivers, or located next to the dangerous shoals, along the Jialing River there are Kuzhu Pass, Dahou City, Yunshan City, Qingju City, Diaoyu City, Duogong City, along the Qujiang River Dehan City, Pingliang City, Xiaoning City, Daliang City, Tuojiang River along the Yunding City, Hutou City, along the Yangtze River Baidi City, Shenjian City, Tiansheng City and so on. They rely on the Jialing River, Qujiang River, Tuojiang River, and Yangtze River, and they rely on each other at angles to form a tight military defense line.

In front of these mountain cities, the Mongol iron cavalry lost its speed advantage, and the mountain cities traveled by boat, which made the Mongols who were not good at water warfare suffer. Blocking the enemy for more than 40 years made it difficult for it to threaten Gyeonggi along the river, but unfortunately, many mountain cities were not conquered by the enemy, but the defenders surrendered to the enemy in a cowardly battle. However, the minister has heard that Lingxiao City is still holding on to this day and has not been conquered by Meng Yuan. Jiang Cheng said.

"Oh, I thought that after Diaoyu City surrendered, there would be no more our army in Xichuan, but I didn't expect that there were still loyal and brave people who insisted." Zhao Yu was a little surprised, in his impression, Diaoyu City still held out for several years after the death of the Song Dynasty, and only reached an agreement with the enemy to surrender in order to protect the people of the city. Now there is still a city under the insistence of the soldiers and civilians of the Great Song Dynasty, which is really beyond his imagination.

"Your Majesty, the ministers think that they can send troops up the river to recover and rebuild the mountain city, restore the defense system, and they can support themselves with the army, and they don't need much food from the imperial court. And once Huaixi is recovered, the situation will further improve, and it can be used as a base to enter Shu and threaten the place where Mengyuan began! Jiang Cheng said.

"Well, it is true that the threat from the upper reaches can be eliminated by taking Xichuan quickly, but I think that the current battle situation is not yet clear, and once the defeat or the war expands, it is still necessary to transfer troops from Huguang to reinforce it. And next month, when the rainy season comes, the river will soar, and the water channel into the river is already flowing rapidly, and the boats are even more difficult to go against the water during the wet season, and the time is no longer allowed. Zhao Yu nodded, thinking that his strategy was advisable, but he made his point of view clear, "But I think that I can strengthen the reconnaissance of Xichuan at the moment, find out the situation, and get in touch with Lingxiao City, and at the same time strengthen the training of mountain attack and defense, and choose the opportunity to capture Xichuan in one fell swoop." ”

"Your Majesty is clear!" Seeing that the little emperor had accepted his suggestion, Jiang Cheng said excitedly.

"Don't be polite, what does it mean for Jiang Dushuai to slow down the attack on Xiangxi and take Dali slowly?" Zhao Yu raised his hand and said. In fact, he was also anxious to need a proper disposal strategy, eliminate potential hidden dangers, and then let go to deal with the frontal enemy, recover the two Huai, and march into the Central Plains.

"Your Majesty, the minister thought that the slang people in the western Hunan region gathered, and our dynasty also implemented the policy of restraint, although they rebelled, but they have been peaceful for more than a hundred years. And Dali and I have always reconciled, and voluntarily become a vassal and accept our dynasty's feudal. If it is to use troops to take it by force, it will inevitably lead to conflict, so it is better to take advantage of its turmoil and endless conquest to implement a gentle policy, lead it to annex itself, and gradually recover Guangxi, making it a barrier against the Mongol Yuan. Jiang Cheng said.

"What about Dali?" Zhao Hao then asked.

"Your Majesty, have you ever heard of the 'White Army'?" Jiang Cheng asked with a slight sigh.

"Bai Jun, I haven't heard of it? Where did it come from? Zhao Yu thought about it, there was no such number in the Great Song Army, and there was no impression in the memory of his previous life, he shook his head and said.

"It's no wonder that Your Majesty doesn't know that this military number is not owned by my dynasty, and it has disappeared for thirty years, if it weren't for the ministers guarding Huguang, ...... would know nothing!" Jiang Cheng smiled, and then talked about the origin of this army.

In the first year of Baoyou, in order to defeat the Southern Song Dynasty, Mongolia marched into Dali to form a siege of the Southern Song Dynasty. The prime minister of the Gao clan led his troops to resist being killed, and the king of the Duan clan fled and was later captured. Kublai Khan named the last king of Dali as the hereditary governor of Dali, managing the area near Dali City, and named a son as the king of Liang, hereditary governor of Yunnan. The subsequent Mongol military control of Yunnan.

In the first year of Kaiqing, when Meng Ge launched a large-scale war to destroy the Song Dynasty, he ordered Wuliang Hetai to send troops from Yunnan and go north through Guangxi, preparing to form a flanking attack on the Southern Song Dynasty. He led his troops from the southwest to break into the Song realm, hoping to go north to join the main force led by Kublai Khan in Tanzhou. The Song army was on the front line of Hengshanzhai and Laocangguan near Yongzhou, with tens of thousands of Chen soldiers, to intercept the advance of the Mongolian army. Under the command of his father, Ah Shu "sneaked from the middle road" to bypass behind him, "rushed to the backbone", broke the Song army, and successfully broke through the Song army's obstruction.

At the end of this battle, the first army of Wuliang Hetai progressed smoothly, along the way to Guizhou, ravaged Xiangzhou, entered Jingjiang Mansion, Lian Pochen, Yuan Erzhou, and reached the city of Tanzhou. However, it was difficult to replenish the casualties along the way, and Duan was grateful for Kublai Khan's grace of not killing, and recruited the children of the white barbarians and the barbarians to form the White Army, which was led by Duan Fu, the uncle of Duan Xingzhi, the king of Dali, and went out with the Mongol army to assist him in the battle. Rendezvous with Kublai Khan in Ezhou and garrisoned along the river.

Later, the Mongol Great Khan Möngke was killed in the battle of Diaoyu City, and Kublai Khan returned to Mongolia to inherit the throne. He did not trust the Wuliang Hetai, and in the second year of Jingding, he dismissed the Wubu and the White Army. At that time, the area around Xiangchuan, Qianyu and Chongqing was still controlled by the Southern Song Dynasty, and the transportation was blocked, so some of the Bai army still followed Duan Fu back to Yunnan, while most of the soldiers were displaced in the areas along the Yangtze River.

After Kublai Khan captured Jiangnan, Mongolia first established the Marshal's Mansion in Dali, the old land of Dali, and then changed to the Marshal's Mansion of Dali, and then changed to the Yunnan Zhulu Xuanwei Division, under the jurisdiction of 10,000 households, 1,000 households, and 100 households. In the year of Chunyou, Kublai Khan began to set up a province in Yunnan, appointed Saidianchi as the political affairs of Pingzhang, changed 10,000 households, 1000 households, and 100 households to roads, prefectures, prefectures, and counties, and Yunnan entered the normal administrative management stage from the period of military control, and moved the capital from Dali to Zhongqing, ending the 500-year history of Dali as the capital of Yunnan.

When Yunnan Province was established, in order to limit the power of the province, the Mongolian princes were divided into towns and guarded Yunnan, and assigned them jurisdiction and territories, which were not subject to the constraints of the province. The Duan clan of Dali is the "hereditary governor of Dali", with jurisdiction over Dali, Shanxi, Weichu, Tongya, Huichuan, Jianchang, Tengyue and other cities, and demarcates western Yunnan as its jurisdiction, forming a pattern of three ruling families of Mongolian princes, provinces and Duan's governors.

"Jiang Dushuai wants to take advantage of the familiar terrain and humanities of these white troops left in the south of the Yangtze River to assist our army in capturing Dali, but there are only 10,000 people, and after more than 30 years, they are all old, and how many people can fight?" After hearing this, Zhao Yu had already roughly understood Jiang Cheng's strategy, but he still had questions.

"Your Majesty is not bad to say so, but this clan is not comparable to ordinary people!" Jiang Cheng said with a smile, "The family claims to be the descendants of Zhuan, Zhurong, Ban Biao, and Ban Gu, because the Ban family was enclosed in the late Eastern Han Dynasty, so the name of the fief was used as the surname, and with the rise and fall of the clan and continued to move south, successively through Yong, Shu and into Yunnan. By imitating the village stilts, changing to obey its customs and intermarriage, it was integrated with the local people, and gradually razed. ”

"In the past, I only heard that the Han people in Nandu were educated by foreign races and returned to Wanghua, but there are still Han people who have been razed by foreign races, which is really rare!" Zhao Hao listened with interest.

"When he first saw this verse, he was also very surprised." Jiang Cheng nodded yes and said, "After the Fu clan gained a firm foothold in Yunnan, it rose rapidly, first appeared in the Shu Han Dynasty, and was strong in the Eastern Jin Dynasty. It was not until the seventh year of Xuanzong Tianbao of the Tang Dynasty that Luo Feng, the king of Nanzhao who was supported by the Tang Dynasty, defeated the Fu clan, and completely ended the history of the Fu family dominating Tiannan for more than 400 years. ”

"So the Fu clan was also a royal family, but today, hundreds of years later, after the reign of Nanzhao and Dali, they are afraid that they have already declined and are no longer prosperous!" Zhao Hao sighed lightly and said. For hundreds of years, even the royal family has long been submerged in history, and only the Ah Q-style lament of 'ancestors have also been rich' remains.

"Your Majesty's guess is right, during the Sui and Tang dynasties, the Fu clan was divided into two parts, east and west, roughly bounded by Qujing to Jianshui. The eastern part is dominated by the Wuman, and the western part is dominated by the Baiman, which is known as the East Wuman and the West Baiman, and the family name also became a racial name by the surname. Jiang Cheng continued, "After the division of the Fu clan, dozens of large and small tribes were gradually formed, but both Nanzhao and Dali needed their support to sit on the throne. And because they are dissatisfied, they often start rebellions and fight against other tribes. ”

In this way, although the Fu clan has been divided, it still has a lot of power, which is enough to affect the rise and fall of a dynasty. Jiang Dushuai meant to use these exiled Bai troops in the south of the Yangtze River to contact the old clans, assist our army in expelling the Mengyuan forces from Yunnan, establish a pro-Song regime, or be included in the territory of our dynasty, so as to eliminate hidden dangers. Zhao Yu said.

"Your Majesty, the minister didn't think so far-reaching, he just thought that he could use the power of the remnants of the Fu clan to defeat Meng Yuan!" Jiang Cheng chuckled.

"I remember that when I recovered Huguang, I captured many Tuntian troops set up by the Meng Yuan, such as the Li soldiers, the Dong soldiers, the Qi soldiers, and the She soldiers, from which Ding Zhuang could be selected to form an army to appoint the obedient leaders of our dynasty. You can promise that if they help our army regain the lost territory, appoint them as officers, and we will discuss the other details in detail! Zhao Yu thought that he could also use these people to form a 'return to their hometowns' to help them return to their old land, and then use these pro-Song people as officials and use the preferential policy to achieve rule and reduce the occurrence of rebellions......
