Yunnan.

In leap March, the Tatar Anyuan Jingkou general Xinjun Wang Doni withdrew his troops from western Yunnan, and some troops in the Eight Banners were unwilling to stay in Yunnan for a long time.

The Eight Banners soldiers left behind their horses and armor, and returned to Hunan through Guizhou with only their personal weapons, and began to take a boat in Hunan, returning to Beijing along the Xiangjiang River and the Yangtze River through the Zhenjiang Grand Canal.

Doni's inadvertent decision to have an eight-banner field force appear at the most suitable place at the most suitable time, which had a fatal and decisive impact on the battlefield of Nanjing on the Yangtze River, combined with the storm that destroyed the fleet in the Yangshan Islands in 1658, perhaps the Tatars really had a destiny.

The rest of the Eight Banners continued to be stationed in Kunming.

Yunnan is characterized by many mountains, all of which are vast and high mountains.

The intermountain basin is called the dam or dian, and the dian is generally smaller than the dam.

The dam is a relatively densely populated area, developed into a state and county, and the western Yunnan region is inaccessible, and these dams that are divided by mountains are relatively independent.

Nearly 10,000 family members of Wu San Province and Shen Yan's soldiers went south from Nandian and stopped at Zhenkang Mansion.

The area of Mengding further south was repeatedly harvested by the Ming army that arrived in the early stage, and the field was plundered, and if it moved forward, the army would only disintegrate.

Wu San Province had no choice but to order his troops to turn east and attack Mengmian (Lincang City).

There was no way back for the Ming army to besiege the Tusi walled city, cut wood to build siege equipment, concentrated the last gunpowder and bows and arrows to cover the soldiers to climb the ladder to the city, the Ming army killed the red eye, three days of bloody battle after the attack into the city, the supplies of the Mengmensi let the Ming army take a breath and climb back from the death line.

The Ming army rested in Mengmian for 2 months, collected grain, killed the local old and weak, plundered the young and strong and livestock, and continued eastward, crossed the Lancang River, and entered Weiyuan Tusi Prefecture (Jinggu County), and concocted it in the same way.

From Weiyuan along the Gongxiang Road opened up by Nanzhao to the south, the team can ride a horse for 10 days to reach the Cheli Xuanwei Sicheng.

Weiyuan is hidden deep in the immeasurable mountains, has not passed the army, the rain and heat conditions in the dam area are very good, the scenery is beautiful, the climate is pleasant, the key is to have food.

The Ming army and its families captured nearly 20,000 people and more than 2,000 cattle, horses and goats.

Wu San Province decided to wait for the autumn harvest in Jinggu, and sent a pioneer to arrive in the car in advance to find Li Dingguo's traces.

September 29, 13th year, 1659.

Yuanjiang Mansion sent people to Jinggu via Pu'er, crying blood for help, and Wu Sanxing and Shen Yan only found out that Yuanjiang Mansion actually had an ally army.

In July, Yuanjiang Tusi Nasong and Shiping commanders Xu Mingchen, Gao Yingfeng, and Jianshui Tusi Long praised the uprising, occupied Shiping, and marched to Mengzi.

The Tatar commander Doni and half of the Eight Banners stayed in Kunming, and sent Gushan Ezhen Zhuoluo to lead the other half of the Eight Banners and Wu Sangui to send troops to southern Yunnan.

The Yuanjiang Ming army retreated from Shiping and other places to defend the Yuanjiang Mansion City. Yuanjiang Dam is located in the vast Ailao Mountain, the Yuan Dynasty dug the channel road before the basic isolation from the world, now is the choke point of the road from southern Yunnan to western Yunnan.

Na Song sent several waves of envoys to look for Li Dingguo, but he couldn't get in touch for two months, but he heard that a Ming army had come to Jinggu in Pu'er, and a team of envoys turned north to find Wusan Province.

After Shen Yan consulted with Wu Sansheng, he immediately decided to help, the Ming army was getting smaller and smaller, and it was impossible for Wu Sansheng to die without help.

The Ming army had less than 1,000 horses left at its least, and recovered somewhat after receiving some replenishment at Mengmian and Jinggu.

Shen Yan selected 1,000 horses, picked 500 soldiers, 1 person with two horses, and set off with the messenger.

The reinforcements first went south to Pu'er, and then marched to the Yuanjiang River through Gongshun Prefecture (Mojiang).

Shen Yan walked the most precipitous road in the Ming Dynasty, the narrow official road shuttled between the mountains and valleys, there were thirty or forty kilometers of long uphill and long downhill in a row, in the morning was often shrouded by the uplift fog caused by strong convective air, nothing could be seen, and if you were not careful, you might fall down the Grand Canyon thousands of meters deep, which was a huge test for people and horses.

Shen Yan arrived in Yuanjiang Prefecture on the seventh day of October, and Wu Sangui's more than 20,000 troops reoccupied Shiping Prefecture seven days earlier, which was a stone's throw away.

The soldiers and civilians defending the city held swords and watched in silence at the few reinforcements.

Na Song's Zhengya, the leading figures of Yuanjiang Mansion are here, including Na Song, Na Tao, Gao Yingfeng, Xu Mingchen, Sun Yingdou, Na Song's son-in-law, Mu Tianbo's second son Mu Zhongliang.

Listening to the messenger who reported that Li Dingguo had not been contacted, the generals of Yuanjiang could only look up to the sky and sigh.

Gao Yingfeng said hatefully: "I really should have made an appointment with King Jin and then started again." The king of Jin moved his troops north to Yongchang Mansion, Wu Sangui will lead the army westward, and we will take advantage of the void to attack Kunming, so that Wu Sangui will suffer the enemy on his back. ”

Sun Yingdou frowned, "Old Gao, Wu Sangui is about to come to the city, what's the use of saying that now?" ”

Xu Mingchen said to Na Song: "Ministry, Wu Sangui sent someone to deliver a letter, as long as you dedicate me and Lao Gao, you can still continue to be toast." ”

Na Song slammed the table, "Wu Sangui is farting." The three of us are in the same heart, how can we change our hearts because of life and death? ”

Na Tao rubbed his palms and said: "My father wrote a reply letter to Wu Sangui, listing all his crimes since Jiashen year, and the envelope is signed by Wu Sangui, the chief soldier of Shanhaiguan. ”

Xu Mingchen shook his head and smiled bitterly, "Why should the ministry be like this, now you and Wu Sangui have no room for compromise." ”

Na Song has a straightforward temperament, "Fight is it, it's a big deal to die with the city." ”

Shen Yan clasped his hands into fists and said aloud to the generals present: "Don't be so pessimistic, everyone, defending Yuanjiang is a battle that must be lost, it is better to withdraw with me." ”

Na Song shook his head and said: "Yuanjiang is the foundation of my ancestors, rather than being chased to the wilderness and dying in the so-called wilderness, it is better to die in this Yuanjiang Mansion, worthy of the Son of Heaven and worthy of the ancestors." ”

Shen Yan was so anxious that he stomped his feet, "That courtyard, you don't know in Yunnan, we Guangdong have some arrangements in Nanyang, as long as we retreat south to the Eight Hundred Xuanwei Division, everyone can live." ”

"Eight hundred, Chiang Mai?"

"Yes, does the ministry have a map?"

"Of course."

Xu Mingchen and the others were confused.

Yuanjiang Mansion is the choke point of southern Yunnan, and Na Song knows his neighbors to the south very well.

Shen Yan spoke in detail about the situation in the Golden Triangle.

Na Song tore off a few whiskers, "The King of Siam is indeed on the northern expedition of eight hundred, will he accept us?" ”

"I promise, there is no problem with King Nare's attitude."

Na Song walked back and forth in the hall for a few steps, and quickly made up his mind, "That's all there is to it, Na Tao." ”

"Father."

"Take the old and weak women and children in the city and leave."

"Father, what about you?"

"I'll block Wu Sangui in Yuanjiang, otherwise you won't be able to leave."

"No......"

Na Song slapped his son to the ground, gritted his teeth word by word, and said, "I'm here, and I haven't said it!" ”

Xu Mingchen stood up suddenly, "That courtyard, I will guard Yuanjiang with you." ”

Na Song smiled, "Xu Zhentai." ”

That night, Yuanjiang Mansion prepared to travel far away.

Nasong opened the city, and allowed the subjects to go out of the city to fend for themselves.

November 22, 1659, light snow.

In tears, Natao led the soldiers and civilians who were willing to go to the west, accompanied by 4,000 Ming soldiers and their families.

In Yuanjiang City, Na Song, Xu Mingchen and more than 300 soldiers, more than 300 old people who did not want to be a burden stayed behind.

On November 23, Wu Sangui besieged the city.

The Tatar battle flag is full of mountains and valleys. At the top of the mountain, Shen Yan put away the binoculars and turned to leave.

While the Ming army retreated, they blocked the roads with large stones and giant logs.

The troops of Wu San Province joined forces with Shen Yan, and the population under the control of the Ming army exceeded 25,000 men.

The first month of 1660.

Gao Wengui, one of the three general soldiers who participated in the bloody battle of Mopan Mountain, died of illness, and Yang Wu stole his position and abducted this Ming army with strong combat effectiveness to go east.

Wu San Province gathered most of the field forces to intercept on the way, killed Yang Wu, and collected 3,896 soldiers and 2,200 horses.

The Ming army continued to search for the king of Jin, and Wu San Province confirmed that Li Dingguo was not in the car and that he was in trouble at Menggen.

The Dingguo Department searched for food everywhere and forced the Menggong Tusi to rebel, and the Ming army fell into a war with the Tusi, and the Shan State in northern Burma was frightened by the possible invasion of the Ming army, and gathered troops to reinforce the Menggong who fought against the Dingguo.

There is no immediate danger to the country.

He Jiuyi's troops retreated from Nanning, Guangxi, and rode nearly 10,000 horses, and Kunming had been lost when they arrived at Lin'an Mansion (Jianshui), He Jiuyi led his troops to withdraw to Xishuangbanna through the Yuanjiang River a few months ago, and then joined forces with Li Dingguo, this Ming army was not damaged in battle, and its strength was relatively complete.

The number of troops in Dingguo exceeded 10,002, and Tusi and Shan Bang had no way to take him. It's just that Tusi cut off the road, and the three provinces of Wu have a lot of family members and coerced population, so it's quite troublesome to fight all the way.

The car was swept by He Jiuyi, there was no food in the field, the population of Jinggu was approaching 30,000, and it would never last for the next autumn harvest.
