This situation will basically not happen, because Li Shimin has already planned it, and even if it happens, it will not change the result of the "Xuanwumen Change".
First of all, Li Shimin's biological mother, Empress Dou, had died as early as the ninth year of Sui Daye, otherwise Li Yuan would not have let himself go so much, and gave birth to a large number of children in his later years. Even if she is still alive, she will not live with Li Shimin, but in the palace.
If someone wants to kill Empress Dou, the nature will change, will you deal with Li Shimin, or against Li Yuan, Li Jiancheng, Li Shimin's father and son? This brain circuit leads to the moon, right?
If it is aimed at Li Shimin's wife and concubines, this is indeed a big problem, because at that time, in addition to Li Shimin's own family, there were also the families of the backbone members of the Qinwang group who were hiding in Li Shimin's Hongyi Palace, and their threat meant that the entire Qinwang group was shaken.
But we don't have to worry, it is clear that Li Shimin has considered the various possibilities of the "Xuanwumen Change". Let's look at the picture first, starting from the location of Hongyi Palace and Xuanwu Gate.
Li Shimin originally lived in the Chengqian Hall of Taiji Palace, and after defeating Wang Shichong and Dou Jiande, Li Yuan specially built Hongyi Palace for him in order to commend Li Shimin.
The scale of Hongyi Palace is very large, the building complex is huge, it has been repaired for three years, and Li Shimin moved in here in the seventh year of Wude.
However, Hongyi Palace also has a disadvantage, because the area is too large, and it is difficult to find a place in the prosperous area of the city, so it was repaired outside the city. Yes, the dignified Qin Wangfu is not in the city, but in the northwest outside Chang'an City, and the location is a bit off.
But precisely because it is very biased, it has brought great convenience to the "Xuanwumen Change".
It can be clearly seen from the map that one or two miles east from Hongyi Palace is the Fanglin Gate of the North City Gate of Chang'an City, and then one mile to the east is the Xuanwu Gate, which is very secluded from here at night, and it is convenient for marching.
The night before the "Xuanwumen Change", most of Li Shimin's army entered the Taiji Palace through the Xuanwu Gate from this road.
Not far from entering Chang'an City from Fanglin Gate is the West Gate Yunlong Gate of the West Garden of Taiji Palace, and you will enter the core complex of Taiji Palace through the Jiayou Gate of the East Gate of Yeting Palace.
Jiayoumen is very important, Li Shimin specially sent his personal guard An Yuanshou to guard here, because the temporary command center of the "Xuanwu Change" is in the corridor east of Jiayoumen, and it is also Li Shimin's escape channel in case the incident fails.
To the south of the corridor is the Chengqian Palace, and Li Shimin will not get lost if he closes his eyes. To the north of the corridor is the Three Great Lakes and the Linhu Palace, where Li Yuan and the prime ministers were imprisoned that day.
From the geographical location, we only discovered a secret, no wonder Li Shimin put the location of the ambush Li Jiancheng in Xuanwu Gate, and put Li Yuan under house arrest in Linhu Palace, everything was decided because of the location of Hongyi Palace.
What does this have to do with the stem? Don't worry, let's get to the point.
The "Xuanwumen Incident" is nothing more than two issues to consider: first, how to succeed in the sneak attack, and second, what to do if it fails? We will not discuss the first question, but only the second.
The so-called "miss" involves two problems, one is that the whole plan failed, and the other is that someone copied the back road in the process of action, and Hongyi Palace was ended.
In fact, in response to these two problems, Qinwang Group has made a well-prepared plan.
Plan 1: Retreat to Luoyang, occupy eastern Shaanxi and engage in secession.
Many people didn't notice this, a few months ago, Li Shimin sent his henchman Zhang Liang to lead more than 1,000 warriors to sneak into Luoyang quietly, with the task of "making friends with Shandong heroes". The history books say very vaguely, in fact, the so-called "friendship with Shandong heroes" is to mobilize local wealthy clans around Luoyang to organize armies and prepare to occupy the eastern Shaanxi region by armed force.
Therefore, as early as a few months ago, Li Shimin had already played the first card, and Luoyang was the last straw, bottom line, and life-saving money of Qinwang Group.
You may ask, Shaanxi is so easy to occupy? How can a Zhang Liang have such great ability?
That's right, at this time, the number one leader in eastern Shaanxi was Li Yuan's confidant Wen Daya, but what Li Yuan didn't know was that Wen Daya had long been Li Shimin's person, and he was also one of the promoters of the "Xuanwumen Change". has Wen Daya's support behind the scenes, Zhang Liang manipulates in front of the stage, and Shaanxi Dong is no problem.
Plan 2: Build two lines of defense and defend Hongyi Palace.
From the previous topographical analysis, we know that if you want to sneak attack Hongyi Palace, you must pass through Fanglin Gate, so Li Shimin built the first line of defense here, and the person in charge is Gao Shilian, the uncle of Li Shimin's wife, Changsun.
However, Li Shimin did not have many people in his hands, according to historical records, there were only 800 people. However, these were secretly recruited by Li Shimin, and the imperial court should allocate no less than 1,000 people.
Even so, there are at least four battlefields in the palace, namely outside the Xuanwu Gate, inside the Xuanwu Gate, the Ganlu Palace, the Liangyi Palace, and the Yongchun Gate. In fact, there were only 70 people in the Xuanwu Gate where Li Shimin faced off with Li Jiancheng and Li Yuanji, so how did Fanglin Gate distribute the troops?
In fact, there is not a single soldier here in Hong Lam Gate, and Gao Shilian has activated the "special forces" - death row prisoners.
It turned out that Gao Shilian was the governor of Yongzhou at the time, and the prison in Chang'an County was under his jurisdiction, so he took advantage of his position to release the prisoners, and set off from Guangdefang and arrived at Fanglin Gate after a quick journey of seven miles. How many people in this team have not been explained in the history books, and it is estimated that there will be no less than two or three hundred people.
The second line of defense is the city defense system of Hongyi Palace.
As we explained earlier, Hongyi Palace is very large, not a simple building, but a huge building complex, surrounded by city walls, moats, and three city gates to the south, so Hongyi Palace is not so easy to attack.
On the day of the incident, most of the civilian officials such as Fang Xuanling and Du Ruhui stayed there, and the commander of the army should be the veteran Qu Tutong.
What is the number of troops left behind in Hongyi Palace? The history books have not explained, it should not be many, and two or three hundred people is the upper limit. However, on that day, all the family members of the core members of the Qinwang Group were gathered here, and they and the servants should all be dressed in battle, and it would not be a problem to gather a thousand people.
Is it safe to have an army town and a city wall to do natural hazards, and there is Gao Shilian's head cannon Hongyi Palace in front? Not necessarily, it depends on the number of troops attacking.
If the first battlefield of the "Xuanwumen Change" fails, that is, Li Yuan cannot be hijacked in the Ganlu Palace, it means that the entire plan has failed. In this way, Li Yuan can wave tens of thousands of horses from the Twelve Guards to attack Hongyi Palace, unless Lao Qu suddenly becomes Sun Wukong, he will definitely not be able to defend it.
Of course, in this case, Li Shimin would definitely not wait for the twelve guards to attack, but quickly evacuated from Jiayoumen, Yunlongmen, and Fanglin Gate, and led his family to flee to Luoyang.
What if the overall situation goes well, but they are attacked by Li Jiancheng and Li Yuanji? Then let's take a look at how many soldiers and horses they have.
According to historical records, Li Jiancheng recruited 2,000 people privately, and his normal guards should not be less than 2,000 people, plus Li Yuanji's guards, the total number of people is about 5,000.
In terms of quantity, the number of Changlin soldiers of Li Jiancheng is at least twice that of Li Shimin, but in fact, it is also stretched.
These men and horses were divided into two parts, one part escorted Li Jiancheng and Li Yuanji into the palace with more than 2,000 guards, and these people were stationed outside the Xuanwu Gate and waited for the two to go to court, and the remaining part stayed in the palace to be on duty.
After the battle began, the Changlin soldiers who stayed in the palace and Li Yuanji's soldiers poured out, but they were blocked by the soldiers and horses of the Qin Wangfu at the Yongchun Gate at the south gate of Taiji Palace, and the two sides broke out into an inspiring battle, and they could not get out until the end of the incident, so this part of the men and horses had no way to rescue Li Jiancheng or attack Hongyi Palace.
There are only more than 2,000 people outside the Xuanwu Gate who may really threaten Hongyi Palace, but if these people and horses go to attack Hongyi Palace, it is indeed terrifying enough. In fact, they did want to do it, but they gave up because of an accident.
When the screams of Li Jiancheng and Li Yuanji inside the Xuanwu Gate came out, more than 2,000 Changlin soldiers outside the Xuanwu Gate, under the leadership of Xue Wanche, Xie Shufang, and Feng Li, broke out a fierce battle with the soldiers and horses of the Qin Wangfu.
In terms of quantity, the soldiers and horses of the Qin Wangfu are less than one-fifth of the Changlin soldiers, and they are definitely not opponents, but don't forget, the thoughts of the Changlin soldiers are not at all in the soldiers and horses of the Qin Wangfu, but Li Jiancheng and Li Yuanji in the Xuanwu Gate, so they can only divide a small number of people to fight with the soldiers and horses of the Qin Wangfu, and the rest of the firepower is concentrated to attack the Xuanwu Gate.
One side is attacking with all his might, and the other side is desperately defending, although the Changlin soldiers have the advantage in numbers, but there is harassment behind them, there are city walls in front of them, and whether they carry siege equipment, the difficulty can be imagined.
The key is that time waits for no one, if it is delayed for a long time, people die, even if it breaks through the Xuanwu Gate, it is meaningless.
At this moment, Xue Wanche had an idea: You Li Shimin are hiding in the Xuanwu Gate, I can't do anything about you, but I can bypass you, take your lair, and use your wife and children as hostages, see what you do!
So he shouted loudly and was about to lead his subordinates to attack Hongyi Palace.
This change made the soldiers and horses of the Qin Wangfu shocked, although there were two insurances, but after all, the strength was limited, in case the rest of the Changlin soldiers also came to reinforce it, it would be troublesome.
Just when the soldiers and horses of King Qin outside the city were desperately blocking it, another person's inspiration changed the situation. This person is Wei Chigong, he cut off the heads of Li Jiancheng and Li Yuanji and took the head of the city: Your master is dead, there is no point in resisting any longer!
Damn, isn't it because someone is giving bonuses? Now that the people who rewarded are dead, they are still fighting a fart?
So the Changlin soldiers dispersed in a hurry, Xie Shufang and Feng Li dismounted and cried when they saw this, and then fled. Xue Wanche was stupid, there were only a dozen cronies left under his hands, and if he didn't run, he would become a light pole.
In this way, Hongyi Palace was dramatically not attacked.
Judging from the whole process, the Qinwang Group has made detailed preparations for the "Xuanwu Change", taking into account various accidents and response plans, they not only protected Li Shimin's family, but even the families of the backbone have not forgotten.
Li Yuan, Li Jiancheng, and Li Yuanji were attacked in an unsuspecting situation, and it was already great for someone to think of counterattacking Hongyi Palace in a hurry, and the probability of success was too low.
