After the pacification of Jiaozhi, the forces of the imperial court entered the territory of the "Great Yi Ning Kingdom" established by the Yang clan from the three directions of southern Sichuan, Dunijiang (Nanpan River) and Zhu Yuanshui (Red River), and restored the rule of Jiannan Province during the Tang Dynasty.

At the same time as the Tang Dynasty perished, the Nanzhao Kingdom, which was divided in Jiannan, also went to the end. There have been the "Great Changhe Kingdom" established by Zheng Maihe, the "Great Tianxing State" established by Zhao Shanzheng and the "Great Yining State" established by Yang Ganzhen.

In the fourteenth year of the Republic, Yang Zhao staged a mutiny, imprisoned his brother Yang Ganzhen, and established himself as king.

Duan Siping united with Gao Fang and Dong Jialuo, the defenders of Shanjucheng (now Yongsheng), and took the opportunity to raise troops.

In the seventeenth year of the Republic, Duan Siping led the army to defeat the Yang army at the bridge (Diancangshan North Eryuan), and Yang Zhao committed suicide in defeat. After Yang Ganzhen learned the news of the defeat, he abandoned the "Yang Tho Baa City" (Dali) and fled to Weichu Mansion and surrendered to the imperial court.

The Yang forces, under the blows of the Duan Gao coalition army, have lost one after another on the battlefield, and the entire situation of the so-called "Great Yi Ning Kingdom" has been completely eroded in more than a year.

At the turn of spring and summer, the temperature in Jiannan Road is pleasant, much cooler than the hot flashes of Cochin and Quang Nam West Road.

With the cooperation of the naval division, the Sanduo army entered Xiushan County along the Nanding River and marched to Queensland from the south.

And An Xianqi, the envoy of Lingnan West Road, and He Fujin, the envoy of Jingjiang Jiedu, also led the army from Luoxiong to Queensland.

In southern Sichuan, the southern Sichuan Jiedu made Li Renhan attack the Sichuan Mansion (Huili), and the Lizhou Hanyuan town guard Zhang Jue attacked the Jianchang Mansion (Xichang), and the Tang army took the opportunity to enter Jiannan in a big way.

At this time, among the mountains of Ailao Mountain, the troops of the Tang Army stretched for more than 30 miles, and they still maintained organic ties with each other.

Due to the rugged mountainous terrain of Jiannan, it was impossible for the army to maintain a strict military formation on the march since before the army entered Queensland. In order to be safe and avoid accidents, Li Jizhong planned carefully, and ordered the army to slow down the march, and the armies moved forward in response.

Although the speed was not fast, the army of more than 30,000 troops was also mighty when they marched.

At this time, Jiannan, civil strife arose, and after the imperial army entered its place, it did not encounter resistance at all, and everywhere it went, it also saved the Tang army a lot of trouble. After seeing the imperial army, the people of Jiannan, who were fed up with the suffering of the war, were grateful, took the initiative to lead the way for the army, and competed to be guides.

It's just that when Li Renhan attacked Huichuan Mansion, he encountered stubborn resistance.

The Southern Zhao army also had no way to retreat, and Duan Siping's brother Duan Siliang gathered more than 20,000 soldiers and horses, intending to resist stubbornly in the city.

In June, the long red banner appeared in the field of vision of the Nanzhao army.

Li Renhan led 30,000 Nanchuan troops to surround Huichuan Castle, and the battle began.

The drums of war were in formation, and the besieging troops were gathering in formation on the slopes outside the city, and the ranks were in a formation of hundreds of people, and some of the artillery was already on the hill outside the city.

"Why is it that now, the Nanzhao people are still trying to resist the city?" Zhang Jue, who led the army from Jianchang to support, observed the situation at the head of the city and put down the binoculars in his hand and said. He is Li Renhan's nephew, and he is one of the few generals in the imperial court who is related to the main general and has not been transferred.

Now attacking the city is basically not a particularly difficult problem for the Tang army.

"They can't help it, and if they run again, the army will go straight to the city of Yang Tho." Li Renhan said that his troops have been in southern Sichuan for a long time, and they are already very accustomed to crossing mountains and mountains, and he does not have to worry about logistical supply problems because of the water transportation on the Mahu River (Jinsha River).

Therefore, his heart is not in a hurry at all.

Zhang Jue shook his head and said: "The order above is to capture as many prisoners as possible, in this Jiannan place, many roads have to be renovated, and there are too many places to employ people." It is easier to build a road from Cochin to Queensland, but it is very difficult to build a road here from southern Sichuan. ”

"That's it, scare them first, and then persuade them to surrender!" Li Renhan said.

At this time, the war drums sounded, and the military formations of several Tang troops besieging the city began to slowly approach the city of Huichuan, and the rumbling cannons rang out, and the shells exploded on the top of the city, raising clouds of fire and smoke.

Red flags flew, and the Don army launched an attack from three directions at once.

At this time, the size of the Huaxia army participating in the siege was only more than 6,000 people. But for the Nanzhao army, which faced the offensive of the imperial army for the first time, it was facing huge pressure. Artillery and platoons of guns, the crossbowmen who suppressed the city could barely return fire, and as long as their bodies were exposed a little more, they would be shot and killed or severely damaged.

The shells scattered the formations of the defenders at the head of the city, and the muskets suppressed their counterattacks. The sword and shield men pushing the ladder easily rushed to the bottom of the city and put the ladder on the top of the city. Cannonballs flew and exploded on the top of the city, and the Southern Zhao army defending the city braved the artillery fire and bullet rain to drop stones and wood under the city.

The casualties of the defenders increased dramatically, and it took a while to discover that the Tang army had not ascended the city, and that the ladders had been erected only to attract the defenders on the head of the city to expose their targets. In the first round alone, thousands of casualties were inflicted on the defenders.

Duan Siliang, who was supervising the battle at the head of the city, understood that the reason why the imperial army did not attack forcibly did not mean that they did not have the ability to forcibly attack the city, but that it was just to continuously consume the strength of the defenders and destroy their will to fight, so as to reduce their own casualties. Before the war, he still had some confidence, after all, his ancestors had also defeated the Tang army and made great contributions to Nanzhao.

Now it seems that he has thought too far.

The advantage of the firearms of the imperial army made the Nanzhao army who escaped from Jianchang Mansion talk about it.

The battle had only lasted for half a day, and Duan Siliang had already personally felt the huge gap in equipment with the Tang army, and the bravery of the so-called barbarian soldiers he had relied on was not worth mentioning at all.

The guns and cannons rang out one after another, and the fighting will of these barbarian troops under his command was rapidly eroding and crumbling.

Thinking of this, Duan Siliang was also a bachelor, and directly ordered someone to raise a white flag at the head of the city.

Waichu House.

Li Jizhong led the army to come, and Yang Ganzhen led the remnants of the Nanzhao "Dayi Ningguo" to go out of the city to welcome the surrender.

After occupying Weichu Mansion, the army led by Li Renhan also rushed to Nongdong Mansion, and the two armies met and went straight to Yangtho City, but An Xianqi and He Fujin, who had just arrived at the border of Queensland, were so angry that they jumped angrily. This marched from Lingnan to Queensland, and the march was difficult, who knew that a battle was not fought, and the two cowards in front were almost finished.

As they expected, Duan Siping saw that the imperial army rushed to Yangtho City, so he wisely surrendered the city, and swore with Gao Fang that the two of them had always been committed to the imperial court. The purpose of this rebellion against Yang is also to return to the Tang Dynasty with Nanzhao.

The imperial court appointed He Fujin as the envoy of Jiannan Town, and promoted Queensland to Kunming Prefecture. In addition, he did not deal with Gao Fang and Duan Siping, and continued to appoint Gao Fang as the defense envoy of Shanju, and Duan Siping as the envoy of Tengchong Mansion.

At this point, the entire Jiannan was also pacified.
