Zhao Ta's Beijing city in his previous life has long been demolished, he has not seen it, the outer city is gone, and the style of the year can be seen from the only few city gate towers and the legendary Forbidden City. But he also knew that to the Jin Dynasty and the Yuan Dynasty, Beijing has become the capital of the two dynasties, and then called the capital of the Ming Dynasty and the Qing Dynasty, after the renovation of the past dynasties can be much stronger and much larger than now, at least the city wall is no longer just rammed earth, but wrapped with city bricks, so that the city wall is more solid, and also added the 'horse face' and the urn city.

But even such a strong Beijing city has been conquered by the Mongols, Khitans and Zhu Yuanzhang and Li Zicheng of the Ming Dynasty, especially in the last years of the Qing Dynasty, the Eight-Nation Coalition only a few thousand people captured the city of Beijing with strong ships and artillery, leaving indelible pain and humiliation to future generations.

It is true that the gains and losses of Beijing often occur at the time of the rise and fall of political power, especially the successive rise of the Khitan, Jurchen, and Mongols in the north. Jin's attack on Nanjing, Mongolia's attack on Jinzhongdu, and Jurchen's entry into Beijing are very good examples, but now history has played a joke with Zhao Ta, at this moment, the Great Song Dynasty has just taken off the hat of being conquered, but it is going to snatch food from the hands of the golden kingdom that is in full swing.

Although Zhao Ta is not a war maniac, but it is not a gas bag that anyone can beat, Jingkang's shame was a thorn in his heart in his previous life, and now he controls the whole country, and is gradually on the right track, now his army is not as good as the foreign devils' modern 'foreign guns and foreign cannons' in terms of equipment, but it is always stronger than the Mongolian Tartar bows and arrows and the muskets and artillery of the late Ming Dynasty, and has received modern military training, he can't pull out this thorn if he doesn't believe it!

But it is not so easy to win this war. Since once the war breaks out, both countries will mobilize the strength of the whole country, and large-scale war. Both sides invested a large number of troops, and the intensity of the battle was deep. The time lasted for a long time and the damage caused was great, and Zhao had to consider the cost gains and losses of the war.

In the battle of Youzhou between the Later Tang Dynasty and the Khitan, the Khitan army claimed to be 300,000, and the Later Tang Dynasty only had 70,000 reinforcements, which lasted for more than 200 days; In the Battle of Gaoliang River, the Song army invested 100,000 troops; The Song and Jin combined to attack Yan, and the Song army dispatched 150,000 troops; In the second and third battles of Zhongdu, the Mongol army besieged the city for six months and eleven months respectively; The Northern Expedition of the Ming Army had 250,000, and even the People's Liberation Army in the Liberation War used the strength of two field armies to complete the campaign deployment.

With the current strength of the Great Song Dynasty, it can support a war. But it can't be a protracted war of attrition or a siege of the city, because even if Yanjing is captured, the ruined city will need a lot of reconstruction funds, and millions of people will have to eat and housing. Therefore, it is necessary to fight a blitzkrieg, solve the battle quickly, maintain the original appearance of the Yanjing area as much as possible, and reduce the damage to the economy, otherwise a war will drag down the economy that has just recovered in the Great Song Dynasty again.

Zhao Ta racked his brains for this. Not only did he turn over all the battle examples that happened in Yanjing in the past dynasties, but he also sorted out the relevant battle examples in his previous life memory for reference.

From the point of view of the location of the battle, because it is restricted by the topography of the Yanjing area, it shows the characteristics of few wars under the city of Beijing and many wars around it. There were not many direct siege wars during this period. There were only six battles, including the Battle of Zhongdu, Zhu Yuanzhang's Northern Expedition, and the invasion of the Eight-Nation Alliance. Most of the war sites were concentrated in the areas around Yanjing, either in the prefectures and counties within their jurisdiction, or in the areas around Beijing bordering Hebei and Shanxi. Such as Zhuozhou, Yizhou, Pingzhou, Bauhinia Pass, etc. The distribution of such combat locations reflects that the war in the Yanjing area was mainly based on peripheral operations, supplemented by siege operations.

In war. There is a clear difference between the direction of the attack and the outcome of the war: the war of attacking Yanjing from the north can often capture the city. The win rate is very large; The operations that launched an attack from the south of Yanjing often failed, and the victory rate was relatively small.

From the point of view of the specific war, the attack and occupation of Yanjing City from the north are: Liao obtained Youzhou, even if there was the power of the Later Jin Dynasty, but it was also the result of continuous military attacks; The Jin army's attack on Nanjing was occupied after breaking through the Juyong Pass; The Jin army occupied Yanshan Mansion and launched attacks from Pingzhou, Juyongguan, Gubeikou and other places, forcing Guo Yaoshi to surrender; The Mongol army attacked Zhongdu three times, all of which crossed Juyong Pass and Gubeikou, and approached the city of Zhongdu, and finally occupied Zhongdu.

But there are exceptions, Abaoji attacked Youzhou in Liao Liguo except for the year, and the siege was not broken for more than 200 days; Then there was the battle of Liangdu, where the Shangdu army crossed Juyong Pass and Gubeikou several times, but they were all defeated by the Dadu army. In the war to attack the Youyan region from the south, except for Zhu Yuanzhang's Northern Expedition, which successfully captured Dadu, almost all other wars were defeated. The Northern Expedition of the Later Jin Dynasty, the two Northern Expeditions of Song Taizong, the two battles of the Song army in the late Song Dynasty to attack Yan, and the battle of Jinbei to aid Zhongdu all ended in failure.

The reason for this situation is that the barriers in the Beijing area are mainly in the north, and once these passes are broken, the city of Beijing will be in no danger; Although the south of Beijing is a vast plain, and the attack is easier than that of the north, the Khitan, Jurchen, and Mongols who occupy Beijing all have strong cavalry, which is more conducive to fighting on the plains, which is also an important reason for the repeated failures of the attack from the south.

Then it is determined by the strategy and tactics of both sides. In terms of strategic and tactical arrangements, the side occupying Yanjing generally adopts the strategy of fighting on the inside line, with Yanjing City as the center and multi-layer fortification, in an effort to contain the enemy on the periphery, even if the enemy breaks through the perimeter and enters the city, it can still hold on and wait for reinforcements.

The side that captured Yanjing City mostly adopted the strategy of fighting on the outside line, withdrawing its shield, besieging the city and sending reinforcements, trying to eliminate the enemy on the periphery and forcing the defenders to surrender. These two different strategies and tactics have made the focus of the engagement between the two sides first unfold on the periphery. Only after the victory or defeat of the peripheral battles is decided, the war will be transferred to the city of Beijing.

In the Northern Expedition of Yongxi, Song Taizong's troops were divided into three routes, divided into joint attacks, and adopted the strategy of external operations. The Eastern Route Army played a leading role, and after the Central and Western Route Army seized the mountain, it was actually to capture the flank of Liao Nanjing, and then the three route armies would join forces to attack Liao Nanjing. On the Liao side, with the defense of Nanjing as the core, the army was concentrated in Nanjing, blocking the Song army in Zhuozhou, and sending Yelu Xian to lead the army to resist the Song army behind the mountain. The Liao army broke through each one, so that the Song army's plan to encircle and cut was shattered, and the battle under the city of Youzhou was avoided.

In the battle of Liangdu, the Shangdu army attacked Dadu from Juyong Pass, Gubeikou, Liaodong, and Zijing Pass; Yan Temur took the division of troops to hold the pass, delay the enemy, and then use the main force as a mobile force, break through each one, and finally defeat the Shangdu army.

In the battle of Zhongdu, although the Mongol army approached the city of Zhongdu, it did not directly attack the city, but the three-way army attacked the Central Plains, so that Zhongdu lost external support, forcing Jin to move the capital to Kaifeng, and the Mongol army occupied Zhongdu; Zhu Yuanzhang's Northern Expedition also took the "first take Shandong, withdraw the other side to shield it, move troops to the two rivers, break its fence, pull out the Tong Pass and guard it, and strangle its household threshold." After the shape of the world is in my hands, and the Yuan capital is lonely, "and then marched into the army and forced Emperor Yuan Shun to flee north."

In short, the choice of strategy and tactics between the two sides also constituted the war in the Yanjing area during the Liao, Jin and Yuan dynasties, which was characterized by peripheral operations and siege operations...

In the blink of an eye, the emperor summoned Gao Chong, Zhao Yong, and Yelu Yu into Beijing, and they held a three-day closed-door meeting with Li Gang, Zong Ze, Xu Zongheng, Zhao Ren, and Zhang Shuye, the secretary of the military department.

Two days after the end of the meeting, Yang Shi, the secretary of the Ministry of Rites, began to play at the court meeting, and Jin Guo once again sent an envoy to request the resumption of peace talks with our Great Song Dynasty. After the ministers discussed, they thought that now that the border situation between the two countries was eased, it would not be a good thing if they could welcome back the Liao King and the captured clan without blood through negotiations, and even if the peace agreement could not be reached, they could fight again. Li Gang and other governors seconded the proposal and thought it was feasible, so the emperor chose to send Ma Kuan, a servant of the Ministry of Rites, as an envoy to Xiongzhou to negotiate with the envoys of the Jin State.

At this time, the imperial court proposed that the original imperial history of Cheng Qin Hui loyal and patriotic to the gold thief captured, now risking death to return to the country, thinking that he had lived in the Jin country for several years to be familiar with the situation of the Jin country, and could choose to send him as a deputy envoy to Xiongzhou to participate in the peace conference, and the ministers felt reasonable. But the emperor did not play it in the court, but issued an edict to recall him to the capital first and ask before discussing.

Ten days later, Qin Hui and his family rushed back to the capital from Dengzhou, the emperor set up a banquet to entertain Qin Hui, and the emperor accompanied him, and the emperor inquired in detail about the situation in his northward journey, and the situation after the Liao King and others arrived in the north. Qin Hui cried and complained that the King of Liao was abused by the Jin soldiers on the way, he could not eat, and he was almost tied to the north, and after arriving in the north, he was humiliated and bowed, and then sent to the Siguo City in the extreme north to be imprisoned. When the emperor heard this, he cried bitterly, almost speechless, and vowed to save the King of Liao no matter how much it cost to return to the country. The next day, he ordered Qin Hui to be the bachelor of Hanlin, and went to Xiongzhou to negotiate with the Jurchens as the deputy envoy of the peace council.

A few days later, another bombshell news came out that the emperor was going out of Beijing to inspect Jiangnan. For a while, the court was shaken, and the ministers played to stop it, saying that the country was still peaceful, but the strong enemy still looked around how to get out of Beijing, and the emperor's patrol cost was huge, and the local greeting and repairing the palace were very disturbing places, in short, they were unwilling to let the emperor leave.

However, the emperor insisted on going his own way and had to go out of Beijing, and the emperor and the empress dowager could not persuade him, so they could only rely on him and began to prepare for the trip. The emperor's patrol was a major event, and the affairs were cumbersome, although the emperor asked everything to be simple, but it was not until after the Dragon Boat Festival in May that the holy car left Beijing...
