Cao Zhizhou's head was full of anger, and he looked dead, and Cao Ergou spat contemptuously when he saw it, so he asked people to pickle it with lime so that it could be spread to the counties of Yali and Lizhou. The name certificate sent by the Yazhou army was not only the head of Cao Zhizhou, but also included the Great Seal of the Yazhou Government and the map and population list of the four prefectures of Yali Diaoyan. According to Ouyang Xuan's instructions, Cao Ergou not only came to defeat the Yazhou army this time, but also to include Yali and Diaoyan and other states into the territory, and completely solve Cao Zhizhou's elbow and armpit problem.

The reason why Cao Zhizhou couldn't turn a blind eye was because he really couldn't figure out how the good situation could take a sharp turn for the worse, he couldn't figure out how Niu Ling secretly withdrew his troops at a critical time, and he couldn't figure out that his henchmen for many years would stab him in the back. In fact, Cao Zhizhou died unjustly, although he and Liu Daer are both heroes on the ruling side, they are also greedy and corrupt people, and they have already made the people angry and resentful, and many of his subordinates have already secretly taken refuge in the Thunderbolt army. The "Fire Fox" in the Meizhou Army was extremely active, and the Yazhou Army was also infiltrated by the Thunderbolt Army. Of course, the biggest problem of the two is that they lack strategic vision, cannot see the general trend of history, and cannot clearly see the impact of the dispute between the two Mongolian khans on the situation in Sichuan. To be precise, Cao Zhizhou did not die at the hands of his henchmen, nor did he die of the treachery of the New Moon, but from the internal strife of the Mongols.

The reason why Niu Lin retreated in a hurry was because he received the shocking news that the secret Huoli and Qitai Buhua had been killed. Both men were close friends with him and pledged their full support for his military operations before attacking Jiading. News came from Chengdu that Lian Xixian was ordered by Kublai Khan to quietly enter Sichuan and kill the Mongol generals who supported Ali Buge one by one. Wang Weizheng, the commander of the Mongolian Dongchuan Marshal's Office, killed the Mongolian general Qitai Buhua in Qingju City, and was also booby-trapped by Liu Heima, who was in charge of Chengdu. Although he remained neutral on the surface, he had many contacts with the Mongol generals who supported Ali Buge, and he was deeply afraid of implicating himself when he learned the news. He took the initiative to withdraw his troops back to Chengdu to prove that he had no objection, and if necessary, he would go to Kaiping, where Kublai Khan was stationed.

The withdrawal of the troops was also because the battle of Jiading had no chance of winning, and it might even be defeated. The secret Huoli and Qitai were not punished to make the Mongolian army in central Sichuan panic, and it was impossible to contain the Song army, let alone send troops to help. The cooperation of the other Mongolian generals that he hoped for was also in vain. With more than 20,000 cavalry stationed in Liupan Mountain, Hunduhai was the largest military force left by Möngke Khan, and his promise to send cavalry south from Longyou to Songzhou and Maozhou also failed when he was killed by Kublai Khan. The direction of Dali was also not good, and Wuliang Hetai was also recalled due to the suspicion of Kublai Khan, and his promise to send troops from Dali to attack Lizhou through the archery furnace naturally failed. The Mongolian army drove the barbarians of Dali to attack the Miaojiang region, but without the strong endorsement of the Mongolian cavalry, the two sides only pecked each other, which had no impact on the Sichuan war situation at all.

Although these diversion actions had an impact on the Battle of Jiading, they were not decisive. In fact, although there was no containment of the Mongolian army such as the Qitai Buhua Department, Yu Xing of Chongqing Prefecture, Liu Cheng of Luzhou and others did not lead the army to relieve the siege of Zan Wanshou, nor did they send some war materials. What made Niu Lin feel that he had no chance of winning was the strong combat power shown by the Thunderbolt Army. If the battle of Pengshan was based on the stone wipe, and because the Mongol army was not good at water warfare, it was acceptable to lose, then the powerful firepower displayed by the Thunderbolt cavalry in the battle to recover Meizhou made him feel afraid. Although the cavalry of the Perak Army was slightly inferior, the infantry was well-trained and the artillery was numerous, and the combination of the two coupled with the overwhelming naval army made the Mongolian army besieging Jiading have no chance of winning. If you don't retreat, it will be absolutely difficult to retreat in your entirety, and you may even be wiped out.

For Niu Lin, if the 10,000 new annexed troops were destroyed, it would only affect the reputation of his famous generals, and at most he would lose his official position and be deprived of the right to lead troops. But if the 2,000 cavalry under his command suffered heavy casualties, even if those kings and nobles interceded for him and the Great Khan spared him from death, he would not be able to gain a foothold in the imperial officialdom, and he would only be spurned wherever he went. Previously, the secret Huoli lost a small number of his own cavalry and hundreds of Khitan cavalry in the battle of Hengyuan Fort, which made him lose the trust of Meng Ge Khan, so that his status was greatly damaged, and he was also hated by Liu Heima, who was also a Khitan. You must know that the cavalry, especially the cavalry of the Mongolian Empire, is the basis of the strength of the Mongol Empire, and the cavalry of the entire tribe is only more than 110,000 people, distributed in a vast territory, and there are only a few in each place, and even in the hands of Kublai Khan, the Khan of Kaiping, there are only more than 10,000 Mongolian cavalry. If the whole cavalry of the new army is destroyed, it will lose its head and even affect the entire family.

Based on the above reasons, Niu Lin abandoned the new annexed army under the city of Jiading, which was definitely not his original intention, and it was really a helpless move. On the one hand, it was to prevent the new annexed army from scurrying around in panic, scrambling for boats to block the ferry, and affecting the cavalry crossing the river; On the other hand, it allows them to continue to attract the attention of the Jiading defenders and block the pursuit of the Thunderbolts. In fact, there were also 2,000 new annexed troops in Jianzhou and Longzhou who crossed the river and returned to their respective garrisons before the arrival of the Perak navy. For the Mongol army, although these new annexes have low combat effectiveness, they are also very useful, and they can undertake logistical garrison tasks such as guarding city strongholds, collecting and transporting grain and grass, and they must also try to avoid losses. But this has a premise, that is, only the Mongol cavalry crossed the river safely, and after reaching the east bank of the Min River, the new annexed army would be allowed to cross the river.

The 2,000 cavalry of the New Wing Department retreated, and only 2,000 of the 5,000 new troops brought by it to Jianzhou, Longzhou and other places returned to the garrison, which can be described as a heavy loss. Of course, they were lucky compared to the new annexed armies in the two states of Meiya, and the two new annexed armies were directly cancelled, and even the commander was in a different position. In comparison, the losses of the Thunderbolt army were insignificant, with a total of only more than 300 people, of which 200 were wounded and more than 100 were killed, of which half of them were the special companies that assisted Jiading in defending the city. The losses in Jiading City were relatively serious, with nearly 1,000 soldiers killed and wounded, hundreds of civilians in the city also suffered casualties, and the damage to the houses in the city was also very serious.

In addition to factors such as strategy, morale, and geographical advantages, this disparity in exchange ratio also reflects the dimensionality reduction strike of the new-type firearms army against the cold-weapon army. Cao Zhizhou didn't look blind, but also because he didn't understand that the times had changed, and behind the fierce firepower of the Thunderbolt Army, it was not only the leading technology but also the reform of the governance model, but also the crushing of the economic foundation. In the Battle of Jiading, the Thunderbolt Army dispatched more than 10,000 people, and tens of thousands of large and small artillery shells were fired, more than 100,000 catties of iron were used in the shells, and the food, gunpowder and other war materials consumed were even more incalculable. The money spent in this battle made Li Shuang, who was in charge of government affairs, jump to his feet with heartache, and urgently ordered all armies to recycle useful materials when cleaning up the battlefield.
