Ten 75-mm field guns, dragged over with a lot of material resources and manpower, far exceeded the frequency of artillery in this era, constantly firing advanced grenades loaded with yellow explosives onto the city walls of Beijing, setting off pieces of rubble and corpses!

Fortunately, after hundreds of years of reinforcement and continuous repair under the crisis consciousness of the Manchu Empire, the wall is still very reliable, and the structure of several layers of walls is used, and there is still one layer of ......

If it weren't for the power of the 75-mm field guns during World War I, the walls of Beijing would not have to worry about being blown down!

In the age of cold weapons, the city defense of Beijing, the capital of the Manchu Empire, was definitely one of the best, and it was much stronger than the diamond-shaped fortress defense system boasted by the whites!

It's a pity that since the popularization of artillery in large numbers, the powerful shrapnel and blasting shells have been continuously upgraded, even the European powers have to give up the seemingly perfect and strong diamond-shaped fortress system, in the era of firearms that keeps pace with the times, no matter how strong the city wall is in the face of a sufficiently large amount of gunpowder blasting, it also seems so fragile, this is only the era of black powder, when the yellow explosives are popularized, the remaining protective ability of the diamond-shaped fortress system has completely disappeared!

The role of the city wall gradually evolved into a mob with backward defensive equipment to suppress civil unrest, and as for the real war between the two countries, it basically did not play a big role......

In the history of the earth in Zhao Dutian's previous life, in the Napoleonic era, the defense capability of the diamond-shaped fortress was greatly weakened, and in the face of Napoleon's army, those noble fortresses became vulnerable, not as much as the French army destroyed by the movement war......

Only the Manchu Empire, which was still in the period of alternating hot and cold weapons, retained a lot of expectations for the city of Beijing......

Under the order of Wang Qiming, the expeditionary force with the Han Imperial Forest Army as the main body rushed day and night, until the city of Beijing, and the Qing army of the prefectures and counties along the way was caught off guard and was cleaned up by the Han army......

Originally, the combat effectiveness of the two sides was not at the same level, and the speed of the Han army's advance was amazing, and the Qing army even lost its ability to organize defense!

When Qianlong Ye heard the rumbling cannons outside Beijing, he made a very decisive and wise choice, and quietly left Beijing overnight with some important Manchu magnates and Janissake!

Qianlong had already experienced the strength of the Han army from the speed and battle reports of the Han army, and he knew very well that when tens of thousands of Han soldiers were approaching the city, the fall of Beijing was only a matter of how many Han soldiers died and how long it took!

The Manchu emperors did not have the generosity of the monarch to guard the country and die, they themselves thought in their hearts that they had stolen the Han people's country, and had been using blockade to keep the black land of the three eastern provinces, in case they could not sit still and steal the country in the future, so that there would be a way out!

Of course, not only the three eastern provinces, but also Mongolia, a small partner who was constantly being co-opted by the Manchus, was also the direction of the escape of the Manchu elites!

Under the continuous marriage and power infiltration, the relationship between the Manchu magnates and the Mongol princes was actually very close, and it can be said that one is prosperous and one is lost!

In the Manchu Dynasty in Zhao Dutian's previous life, the Mongolian cavalry helped the Manchu Empire suppress the Taiping Heavenly Kingdom and confront foreign invading armies!

Even the most warlike monk in Mongolia, Gelling, died in the battle to suppress the rebellion!

The Mongolian cavalry was even killed and wounded on the way to the Manchu Empire!

It can be said that the Manchu Qing Dynasty was able to rule the majority of the Han people with a small number of people, and the hardcore little brother of Mongolia contributed a lot!

Because of this, when the Manchu magnates looked at the Han people, they looked at the slaves, but when they looked at the Mongols, they looked at the eyes of their friends, which can easily be seen in the various preferential policies for the Mongols during the Manchu rule, and the Mongols had a lot of independent rights!

However, because of the close relationship between the Mongols and the Manchu elites, after our Manchu Empire was overthrown by the revolutionary party, the whole of Mongolia was full of hostility to the Central Plains Revolutionary Party, and finally with the help of Tsarist Russia and the Soviet Union, Outer Mongolia completely became independent from the Chinese territory!

The direction of Emperor Qianlong's escape was the Inner Mongolia region, and since the Han army could land from the mouth of Dagu in Tianjin to Beijing without pressure, it could naturally also land from any coastal area in China, so Emperor Qianlong did not choose to flee in the more fertile south, but chose to flee from the land that was solid and had a large number of Mongolian cavalry!

Of course, it was impossible for the Qianlong Emperor to flee to Mongolia in one go, and his first stop was Shanxi, and in the name of the hunting patrol, the Qianlong Emperor would organize resistance to the Han army in the capital of Shanxi, as well as hope for ethereal peace talks......

As for the prestige loss caused by the loss of the capital to the Qing Empire, the Qianlong Emperor could not care so much, at least, the loss of the capital would have a much smaller impact than the death of the emperor......

As long as the emperor did not die, the Manchu Empire had an insurmountable position in the hearts of the people who were loyal to the empire, and resistance and war could be maintained!

Once the emperor is dead, there will be a vacuum of supreme power, which will make a large number of lower-class people lose the direction of struggle, and will also make careerists see signs of chaos, and at that time, I am afraid that it will be a catastrophe for the Manchu Empire!

In the late Ming Dynasty, after Chongzhen hanged himself in Beijing, the reason why the small court of the Southern Ming Dynasty faced the outrageous resistance of the Manchu Dynasty was that the inheritance became blurred as soon as the orthodox emperor died, and the young emperor who was raised was not enough to serve the public, which led to the discord of the Southern Ming court, and the generals who led the troops abroad gradually became warlords, and the prestige of the central court decreased dramatically!

Even, in the Southern Ming Dynasty, there were wars between their own people and their own people!

It is conceivable that the reason why the Southern Ming Dynasty in this state survived for so long was only because the happiness of the Qing army that entered the customs came too quickly, ate too much, had indigestion, and spent a lot of time sorting out the interior......

When the Qing army in the north sorted out the interior and consolidated its rule, the army moved south, and in an instant, the small court of the Southern Ming Dynasty was completely defeated!

With the same vitality as the Southern Song Dynasty in the face of the Mongolian iron hoof and the immortal Xiaoqiang, the Southern Ming Dynasty is simply a typical counterexample!

This is the danger of losing the Orthodox Emperor!

In a centralized feudal state, the change of imperial power in peacetime must be carried out carefully, and the old emperor must repeatedly pave the way for the prince in advance, cultivate confidants for the prince, and make a clear edict. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

This is still the case in peacetime, let alone the change of imperial power in times of war?

Especially after the loss of the capital, changing the emperor is really a fatal errand!

Emperor Qianlong and the Manchu magnates knew this very well, so they gave up Beijing without any psychological pressure!
