The room goes through the late Ming Dynasty, and the back door leads to North America at the beginni

Li Yan said, "At this stage, even if His Majesty surrenders, he may not be able to save his life. In this case, the only way left is to escape to the Western Regions."

Li Zicheng's face brightened slightly.

Although it was a bit unpleasant for Li Yan to say this, he finally considered it for him.

If Li Yan still persuades him to surrender to Wei today, he will never show mercy and will definitely kill him for the crime of torturing Wei!

After coming back to his senses, Li Zicheng said: "Then go to the Western Regions - Xi'an Prefecture is sandwiched between Fengxiang, Hanzhong and Henan Prefectures. It is difficult to defend, so it will be lost if it is lost.

The current plan is to gather as many elite soldiers and horses as possible, bring as much wealth as possible, and go to the Western Regions in order to gain a foothold faster.

Military Advisor Zuo, tell me, if we go to the Western Regions, how should we go? "

Li Yan said, "Since Fengxiang Mansion is occupied by the Yi army, we can only retreat to the north first, and then turn to the west.

It is best to go to Qingyang Mansion first, reach Qingping Pass in the north, then turn west, pass Pinglu Suo, Zhenrong Suo, Xi'an Suo, and Jingluwei to Lanzhou. "

With that said, Li Yan came to the map and pointed at Weiyuan, Longxi and Anding.

"Even if we want to escape to the Western Regions, we can't go directly there. After all, it belongs to Yarkand. Therefore, we need to use the Ganlong area as a temporary place to stay.

The Guanzhong Plain and northern Shaanxi areas are mostly flat and flat. Although it is beneficial to our cavalry, it is also beneficial to our army's chariots and horses to transport artillery.

But the Ganlong area is different. There are many mountains and dangerous passes.

After the main force of our army retreats into Lintao Prefecture, we can set up two lines of defense in the east - Anding, Longxi (governed by Gongchang Prefecture), and Zhangxian as the first line, and Chaoxian, Shouyangguan, and Wuzhushan as the second line.

In the south, you can capture Meichuan, Sanchaguan, Taozhouwei, and Yangsaguan to set up another line of defense.

In the north, you can defend Jinglu Guard and the large and small Songshan forts.

In this way, unless the Yi army uses large groups of cavalry and artillery vehicles to circle the grasslands, they can only attack dangerous fortresses in the Ganlong Mountains.

Even though its guns are fierce, it will take quite a while to do so. In this way, our army will have time to conquer the Western Region. "

At this time, Li Yan pointed at the map and spoke eloquently, clearly explaining the retreat and follow-up defense matters, quite like a commander.

Li Guo and other generals in the palace nodded slightly when they heard this, and felt a little relieved in their hearts - when they first heard that the Yi army had conquered Tongguan, everyone's hearts felt as heavy as a big stone.

However, Li Zicheng saw the expressions of the generals and became more wary of Li Yan.

After Li Yan finished speaking, he loudly said: "The westward retreat route chosen by Zuo Military Advisor sounds indeed appropriate. Then, let's discuss how to break up the rear."

The east and west armies have already defeated Wugong and Tongguan, and are not far from Xi'an.

Even if the Shun army wants to withdraw, it is impossible for them all to evacuate, and they must leave some people behind.

Because they have to carry their belongings and families of soldiers and soldiers, a large team will not be able to move quickly.

Therefore, the troops and horses behind the break cannot be small, and the generals behind the break cannot be too weak. They must at least hold off the Yi army in Xi'an for a few days.

After some discussion, it was finally decided to use Yuan Zongdi as the chief general, Hao Yaoqi and Zhang Nai as deputy generals, and lead 5,000 elite soldiers and 50,000 miscellaneous soldiers to garrison Xingping, Xianyang, Xi'an, Jingyang, Lintong, Gaoling, Lantian and other cities. .

In order to prevent the news from spreading and causing panic, the remaining soldiers and horses may even rebel.

After the meeting, Li Zicheng first asked Hao Yaoqi and Zhang Nai to lead 1,000 elite troops and 10,000 miscellaneous troops, respectively, to the two important cities of Xingping and Lintong.

Then Yuan Zongdi was asked to lead the remaining troops and horses to move to the south of the camp, and strictly ordered the soldiers not to go out.

Then he led the elite main force, took a cartload of property and family members, and walked through Jingyang to Qingyang Mansion.

Nanjing.

Forbidden City, Tianxin Palace.

Director of the Telecommunications Department Zou Runniang walked into the hall with a telegram.

"Your Majesty, Ruyang forwarded a telegram stating that the Guards would attack Tongguan on March 30th."

Liu Sheng took the telegram and read it carefully, showing no special expression.

The Second Brigade of Huben Guards and the Second Brigade of Xiaoqi Guards began to attack Tongguan on March 28. It took three days to break through the city, which was definitely slow in the records of the Wei army's sieges.

It’s not that the Tiger Guards and the Xiaoqi Guards are incompetent.

Tongguan is named Guan, but it is actually a strong city and fortress.

The Shun army guarding Tongguan will not huddle their troops and horses within the city.

In fact, according to the information from Xunfengwei, the Shun army built four large villages, more than a dozen small villages outside Tongguan, and dug dozens of trenches!

It can be said that a heavy trench is dug and a strong wall is built!

This is similar to the Battle of Tongguan in Shunqing Dynasty in later history.

At that time, the Duoduo Division of the Qing Army was the vanguard. It arrived east of Tongguan on October 1644 () and set up camp miles outside Guancheng, waiting for the arrival of the Hongyi cannon.

At that time, the Qing army had invaded northern Shaanxi, and the Shun army was in a dangerous situation of being attacked from the north and the south.

Li Zicheng then personally led his elite troops to support Tongguan.

During the ten days from October 29th to November 9th, the Shun army took advantage of the Qing army's Hongyi artillery to attack several times, hoping to break through the Qing army's camp, but all failed.

On the ninth day of the lunar month, the Qing army's Hongyi artillery arrived, and it became the Qing army's attack and the follow-up army's defense.

At that time, the Shun army did not attach as much importance to the Hongyi artillery as they did in this time and space. They could only respond with strongholds and trenches, and sometimes used fine cavalry to counterattack. They held on until the 12th, when Tongguan was breached by the Qing army.

Although the number of Dashun soldiers and horses in this time and space is not as large as in history, their elite combat power is not much different.

In addition, Li Zicheng attached great importance to guns and artillery. He installed eight red Yi cannons and 24 red Yi cannons for Tongguan (separated into each village, not all on Guancheng), and sent 1,500 musketeers. , and countless boxes of bulky black powder grenades were distributed.

It can be said that the difficulty of conquering Tongguan was several times higher than that in later generations.

The Yi army, with two brigades of guards as the main force, three brigades of garrison troops as supplements, and a number of civilians as logistics, launched a three-day and night attack on Tongguan.

It can be said that the first two and a half days were spent on conquering the strongholds and trenches outside Guancheng.

After the four major villages and more than a dozen small villages were defeated, the Wei army concentrated their field artillery to bombard Tongguan City.

In less than half a day, Tongguan City was captured.

According to the battle report forwarded by Ruyang, nearly 500 people of the Guards died in this battle!

More than 100 people were seriously injured, and more than 3,000 people were slightly injured!

It can be said that a battalion of troops was lost!

As for the garrison, more than 3,000 people were killed and countless others were slightly injured!

It can be seen from this that the battle of Tongguan was not easy for the Yi army.

However, once Tongguan is conquered, Xi'an is open to the Wei army, and it is only a matter of time before it is captured.

Liu Sheng's only worry now is that the Shun army will concentrate its forces and attack Shen Wandeng's tribe in Fengxiang Mansion regardless of losses.

Because in his opinion, this was the only way for Shunjun to regain a slight advantage.

Although even if Shen Wandeng's troops were defeated or even annihilated, the Wei army could still destroy Dashun this time, but it would probably take several more months, adding a lot of variables.

'It's a pity that the radio on hand is not enough. Otherwise, if the Sixth Division of the Standing Army is also equipped with a telecommunications team, we can know what the battle situation is in the west. '

After putting down the telegram, Liu Sheng stared at Fengxiang Mansion on the military map and thought to himself.

As Da'ei's territory continued to expand, most of the radio stations in Liu Sheng's hands were distributed.

Today, Ruyang, Beijing, and the Second Division of the Standing Army each have a telecommunications group. Chengdu (Third Division), Fuzhou (First Division), and Guilin (Fifth Division) also each have a telecommunications group.

In addition to a telecommunications group in Nanjing, seven stations have been used.

It's not that Liu Sheng can't put together another one, he's just worried that after using it, the parts will be damaged and there will be no replacement.

Moreover, the situation in the northwest battlefield cannot be reported immediately by one radio station. At least two radio stations are required, but Liu Sheng simply refuses to give it.

After preparing to capture Shaanxi, a telecommunications team will be arranged in Xi'an depending on the situation to control the military and political situation in the northwest.

Speaking of which, he had already given orders to the Secret Manufacturing Bureau to develop various components needed for the radio.

It's just that with Da'ei's current manufacturing level, it's impossible to manufacture many parts. We can only realize the idea of ​​"Da'ei's own radio station" by waiting for relevant technologies to slowly make breakthroughs.

After coming back to his senses, Liu Sheng couldn't help but look to the northeast on the map, which was North Zhili to be exact.

Liao's Xunfengwei had already sent back intelligence that the Qing army would take advantage of the defeat of the Yi army to invade.

This is also consistent with the inference of the Military Academy Staff Office.

Naturally, Da'ei has already made relevant strategic arrangements.

However, what Da'an wanted was not to keep the Qing army out of the pass and prevent them from joining the invaders.

Instead, they must try to eat up the invading Qing troops in order to reduce the military strength of the Qing Dynasty and pave the way for the future destruction of the Qing Dynasty.

“Now the Second Division has invaded Shanxi, captured Datong Prefecture, and will attack Ningwuguan and Yanmenguan.

There are definitely a lot of Qinglu spies in Shanxi, and they will definitely get the news. In this case, it's time to enter the invaders' pass, right?

But I don’t know where they will choose to enter the customs. "

Liu Sheng narrowed his eyes slightly, and his sharp eyes seemed to be able to see the distant battlefield of Northern Xinjiang through this military map...
