Peng Daya said disdainfully: "Chongqing will be the base to support Sichuan for at least the next twenty years. It will be used to protect the upper reaches of the south of the Yangtze River. It is related to the safety of the country. For such a project, we must treat the money as money. People should not do things for their own purposes, do their best, be foolproof, and be perfect. I believe Dutong also understands this. Now is not the time to care about expenses and cherish people's power. The gains and losses of Chongqing are related to Sichuan. The gains and losses of Sichuan are related to the safety of the entire Song Dynasty. This is the time to devote all your efforts. Every penny spent today and every drop of sweat shed will be rewarded a hundred times in the future. What he is afraid of is gathering at this moment. The officials and generals in Chongqing will not understand this. It is not just Wang Kui, Qin Zhongxiao, and Zheng Yunming who are gathering in Chongqing at this moment. In fact, the remnants of the former capital commander He Jing are gathering in Baishui River. , a small number of Cao Youwen's remnants in Shunqing Prefecture, and the remnants of the murdered Chengdu prefect Chen Longzhi, Zheng Yunming, after receiving Wang Kui's report, quickly sent people with wax pill books to summon them. At this time, they all sent generals to wait for orders. He Yanwei's troops retreated from the north, as well as Yang's troops who came from Bozhou, and Tian's troops who came from Sizhou. Some people were dissatisfied with Zheng Yunming's order to gather troops, thinking that it would be better to scatter them in the areas where the enemy had invaded. The troops in the area were organized on the spot and used as guerrilla forces behind enemy lines when the Mongolian army moved south again. However, Zheng Yunming knew better than anyone else that without strong organizational capabilities, this kind of guerrilla army organized on the spot would not be effective. The Song Army had done so in the past. There are hundreds of thousands of defeated troops in the Jinren's ruling area, and their effect is far less than that of the four major armies on the front line. What's more, there are only a few defeated troops left in Sichuan. As for the troops in Bozhou and Sizhou, no one knows how to use them. Thinking that they came so quickly, it was obvious that after the imperial court received the report of Sichuan's defeat, it immediately ordered the hereditary chiefs of Bozhou and Sizhou to send troops to support them. This also involves the relationship between the imperial court and Sichuan. Since the southern crossing, Sichuan has been in trouble. Mutinies and rebellions have been intermittent, which made the imperial court have a bad impression of Sichuan. When Wu Xi rebelled in the third year of Kaixi, some people in the imperial court discussed abandoning Sichuan. There were voices again that the country could be established without Sichuan. As soon as there was trouble in Sichuan, civil and military officials in Jingxiang were busy setting up defenses at the mouths of the Three Gorges such as Xiazhou and Guizhou. This time Sichuan was defeated and the Mongols invaded in large numbers. He did not think about how to adjust the deployment in time to replenish food and soldiers for Sichuan. Instead, he was busy transferring the core combat force Zheng Yunming from Jinghu. At the same time, he organized the barbarian troops from Bozhou and Sizhou into regular troops and marched into Sichuan. This shows that the imperial court would rather believe in toughness. The cunning Tibetan people also refused to believe in the Sichuan army's combat power and loyalty. To be honest, Zheng Yunming didn't think highly of these Miao Liao barbarians who were dressed in rough linen and had strange turbans on their heads. Although they were brave, they rarely kept discipline. , which is completely opposite to Zheng Yunming's army management philosophy, but Zheng Yunming also knows that this army is the most effective force besides his own troops at the moment, and Miao Liao's mountain infantry and mountain cavalry are proficient in mountain warfare. Although Zheng Yunming's troops They are highly disciplined and move quickly, but when marching long distances in eastern Sichuan, they are often troubled by the dangerous terrain. Although these barbarian soldiers seem to be used to being loose, they really walk over mountains and ridges as if they were walking on flat ground. They walked hundreds of Going to the mountain road and then fighting is as common as eating and drinking. Only by being able to make full use of them can we give the Mongolian soldiers a harsh lesson in the mountains. At this time, Chongqing Mansion gathered tens of thousands of troops and horses from all over the country. Almost all Sichuan generals gathered in the main hall of the magistrate's office in Xiaopailou to listen to the lectures of the new group of Sichuan officials. Since being appointed by the imperial court, the new Sichuan Xuanfu envoy Li Zhi has mobilized a Jingchu naval vehicle and boat from Ezhou, carrying three times the number of soldiers, and took turns to ride straight to the middle of Sichuan, but his speech was just ordinary. He warned the generals not to be arrogant and domineering, to oppress the people, to be loyal to the court, to serve the country with all their strength, etc. There was nothing new in the ordinary tone of ordinary officials. Sichuan Zhizhi envoy Yang Hui was an active militant. Before taking office, he had written to the ministers in the political hall to lay out a strategy to recruit local soldiers from Luzhou, Xuzhou, Rongzhou and Changning counties to form a volunteer army to regain Shukou. These are all prefectures and counties in eastern Sichuan and southern Sichuan. There are many barbarians among the native soldiers, who are strong and capable of fighting. Yang Hui vowed to regain Shukou within one year, and within three years, the Mongols would not dare to face Sichuan. But the generals just listened to the discussion of these two adults. To put it bluntly, these two people plus their official entourage, a hundred or so people entered Sichuan. Although they are the commander-in-chief of one party, the county magistrates are not as good as the current managers. Whether they buy it depends on whether the generals in Shu are willing to cooperate. But this new Zheng Dutong is completely different. Not only did they come by themselves, they also brought tens of thousands of troops. Moreover, the army and horses are strictly disciplined, the military appearance is neat, and they are friendly as soon as they come up.The war started with Wang Shixian, the commander-in-chief of Gongchang who was quite fearful in the country. You must know that Wang Shixian's reputation has long been known to the whole Sichuan. The former Xuanfu Zhizhi Zhao Yanna really spent a lot of effort to win over Wang Shixian. People asked him why. He values ??Wang Shixian so much. He once replied, Wang Shixian is the most powerful general in the world, his bravery is comparable to that of Guan Yu and Zhang Fei. If he has won over him, will he still be afraid of the Mongolian soldiers? This incident may be due to untrustworthy hearsay, but it also reflects the consistent evaluation of Wang Shixian by Sichuan people at that time. Only Cao Youwen from Shukou had an unparalleled army of loyal soldiers who dared to compete with Wang Shixian. But Zheng Yunming not only dared to fight Wang Shixian as soon as he came up, but also killed Wang Shixian and fled. This battle won the hearts of many Shu soldiers and generals in one battle. Although Zheng Yunming didn't feel it himself, the soldiers in Shu already regarded Zheng Yunming as the true representative of the imperial court in Sichuan. Only the strategy of this little Zheng Dutong represented Sichuan's core strategy for fighting Mongolia in the future. Zheng Yunming stood up from his seat and glanced at everyone sitting down. There are cutting-edge military generals from Jingxiang, local generals from Shu, and Miao barbarian leaders from the southwestern Yi. They are a mixed bag, and their combat effectiveness is very different. If we cannot design a correct strategy that suits the current situation in Sichuan, Strategy, it is likely that the Mongols will seize the opportunity and defeat them one by one. "If you want to plan Sichuan's strategy for the next ten years, you must first review the lessons of the past ten years." Zheng Yunming said: "If we don't know what we did wrong in the past ten years, we will not be able to pave the way for a bright future." "The past. In the past ten years, the rulers of Sichuan have not carefully repaired the pass cities and carefully organized and trained the army. They have only focused on recruiting powerful foreign aid. This is not wrong, but it can only be based on their own strength. Only then can we recruit powerful Tibetan people to help." Zheng Yunming glanced at the two Tibetan generals, Yang and Tian, ??who seemed to have no change in their expressions, so he continued: "The soldiers are wearing shabby clothes and eating. They mixed brown rice with sand and gravel, and even dug grass roots to satisfy their hunger, but they used carts and horses and camels to offer countless grains, cloth, gold and silver to Wang Shixian and outsiders from the 18 tribes of Tibet in order to build a good alliance. This is not the case. To win over allies is to use the blood and sweat of the people in Sichuan to support the enemy. The city defense of Sanguan was damaged by the Jin Dynasty, and the morale of the soldiers was depleted. The ordnance was damaged and worn out, and was not replaced in time. Tiantian said that he wanted to advance into Guanzhong and join forces with Wanluo. As a result, the war broke out. Wang Shixian and the Eighteenth Division of Xifan led the Mongolian army to attack Shukou. Langzhong, Hanzhou, Jiangyou, and Chengdu were all affected. This was the insight of the rulers. The reason is unknown. "Who is to blame for this defeat is a matter of great significance to Sichuan's political situation. Everyone in Sichuan is panicked and deeply afraid that the imperial court will be held accountable for this fiasco. They know that the imperial court will be held responsible. He was never merciful to the defeated. After the defeat of the Battle of Luo, almost all the participating generals were demoted three levels in a row. In the Xiangyang rebellion, all those responsible were demoted three levels in a row. The direct culprit, Wang Min, was directly deposed as a commoner. If Zheng Yunming threatened everyone with this, everyone would have no choice but to endure it. Zheng Yunming had his own plans. When he entered Shuzhong, the most important thing was to unite people. Although Yu Jie disagreed with this and insisted on rectifying Sichuan's scattered troops with steel discipline, Zheng Yunming knew how to manage the army first of all, to manage people's hearts. Giving three hundred killing sticks to famous guest generals who come from afar may work in peacetime, but it is by no means the best choice in wartime. He played a trick and put all the blame on Zhao Yanna, the former propaganda envoy who had resigned. It would be unfair to say that the entire Sichuan policy was all Zhao Yanna's fault. The problem in Sichuan as a whole is not just the problem of Zhao Yanna alone. When he reaches out, everyone rushes to be the first, and when the army is organized, everyone slacks off. It is not only the ruthless handling of the troops below, but also the blind command from above. Knowing that attacking Guanzhong from the middle of Shu was a task that even geniuses like Zhuge Kongming could not accomplish, yet it was left to Zhao Yanna to complete it. This must be said that Zheng Qingzhi, the right prime minister at the time, did not have his own private calculations. But Zhao Yanna is a dead tiger after all. Even if he comes back in the future, he will never have the same prestige as before. Hitting him with a stick would be tantamount to exonerating the civil and military ministers in Sichuan, which is exactly what he said, always unite the majority. Zheng Yunming continued: "Sichuan's strength lies in its convenient location. When the outer three passes (the three northern passes with Dashan Pass as the core) were in the hands of the state, the Sichuan army focused on defending the inner three passes (with Wuxiu Pass as the core). After the three outer passes were lost, the core of defense was transferred to Xingyuan and Mianzhou, while the inner three passes were abandoned. After the enemy broke into Xingyuan and Mianzhou, they To defend the Da'an Army, it seems that they are resisting step by step. In fact, it is better to say that the army is not elite enough, the soldiers are not strong enough, and they do not have the determination to defend the enemy from outside the country. Recently, I heard that Sichuan officials have given up on Jiading and Chongqing to lure them. This is the opinion of scholars who do not understand the art of war. The key to the art of war is to make full use of the geographical advantages. Only the enemy's advantages can be used.When the territory is large enough to overcome the geographical advantage, some means of luring the enemy deep into the territory and waiting for opportunities to attack will be used.
