When Gongliangbo, the Tusi of the Southern Dai tribe, learned that his second son, Gongliangzhen, was killed by a Han general during the banquet of the Han Emperor, he was immediately furious, and immediately began to gather the army of the Southern Dai tribe, preparing to discuss an explanation with the Han State.

After Liu Ji was killed by Hu Luguang in Gongliang, he transferred the Southern Xinjiang Army and the Longxiang Army, as well as 500,000 trapped camps, 800,000 white pole soldiers and 800,000 Wei warriors, to the Nanban Protectorate, plus the four million people of the Nanban Legion, the Han Dynasty has gathered nearly 10 million troops in the Nanban Protectorate.

On November 20, the 11th year of the Han Dynasty, Han Xin, the commander of the Nanban Army, Zhuge Liang, the commander of the Southern Xinjiang Army, Lu Xun, the commander of the Southern Xinjiang Army, Cen Wenwen, the commander of the Longxiang Army, Wei Xiaokuan, the commander of the Long Xiang Army, Ma Zhou, the commander of the camp, Gao Shun, the commander of the trapped camp, Zu Li, the commander of the White Pole Soldiers, and Chong Shiheng, the commander of Wei Wushu, gathered in Xing'er City, the state capital of Kangzhou, the capital of the Southern Barbarian Empire.

Xing'er City was originally the location of the Tusi Mansion of the Qiang Nationality, and after the establishment of the Nanban Protectorate, Xing'er City became the capital of a state.

Zhuge Liang, the military advisor of the Southern Dai Legion, said to the others: "According to the information from Heishuitai, now the Southern Dai is gathering troops and preparing to invade our Han Dynasty's Nanban Protectorate. ”

The Kihu have a population of about 50 million and a territory of more than 12 million square kilometers and can gather more than 20 million males, while the Nani have a population of about 60 million and a territory of more than 15 million square kilometers and can gather more than 23 million males.

Ma Zhou, the military advisor of the Longxiang Legion, frowned and said: "If the Southern Dai, Kihu and Nani are united, it is almost impossible for us to end this war in a short time, and with only our three legions and three elite troops, we will not be able to defeat the combined forces of the Southern Dai, Kihu and Nani clans, after all, these three clans together are enough to mobilize tens of millions of men." ”

Gao Shun, the commander of the trapped camp, said indifferently: "At the beginning, the five powerful clans of the Southern Barbarians were united, and they were not also defeated by our Han people, even if the Southern Dai tribe, the Jihu tribe and the Nani tribe formed a coalition army, the iron hooves of our Han army can still step on them!" ”

Lu Xun, the commander of the Southern Xinjiang Army, said at this time: "At the beginning, after a three-year war, our Han was mainly against the Qiang and Lano, although the Southern Dai, Kihu and Nani also sent troops to join the war, but they did not do their best, the three tribes together only lost about four million troops, the Southern Dai, Jihu and Nani basically withdrew from the war, if these three tribes really united, it is not good that our Han will have to experience a protracted war." ”

Han Xin, the commander of the Southern Barbarian Legion, nodded and said: "Among the millions of mountains, it is not conducive to cavalry combat, once the Southern Dai, Kihu and Nani really unite, our Han army can only fight steadily and steadily, and eat away at the Nandai, Kihu and Nani little by little." ”

After a pause, Han Xin continued: "I discussed with Zhuge Military Division, since this war is unavoidable, it is better to take the initiative to attack, and take advantage of the fact that the army of the Southern Dai tribe has not completed the assembly, and take the Southern Dai tribe by surprise." ”

Zhuge Liang followed and said: "There is another advantage of taking the initiative to attack, that is, you can put the battlefield in the territory of the Southern Dai tribe, after all, the Nanban Protectorate has just been established for a few years, and the people of the Southern Barbarian Protectorate are mostly people from the Qiang and Ranor tribes, if the war breaks out in the territory of the Nanban Protectorate, I am worried that some people from the Qiang and Ranor tribes will take the opportunity to cause chaos for our Han." ”

Cen Wenwen, the military advisor of the Southern Xinjiang Legion, nodded and said: "I agree with taking the initiative to attack and choosing the battlefield in the territory of the Southern Dai clan than in the territory of the Southern Barbarian Protectorate." ”

The others looked at each other and nodded, and then Han Xin said loudly: "Your Majesty has given us the right to make a temporary decision, since everyone agrees, then three days later, that is, in the early morning of November 23, we will launch an attack on the mountain cities of the Southern Dai tribe close to the Nanban Protectorate. ”

When the war broke out on November 23, the Southern Dai gathered more than 3 million men in various mountain cities near the Nanban Protectorate.

However, after the outbreak of the war, in less than five days, many mountain cities in the border area of the Southern Dai people were basically conquered by the Han army.

In the Tusi Mansion of Qingkan City of the Southern Dai Tribe, the Tusi Gongliang of the Southern Dai Nationality asked Lu Pukui in a deep voice, "Is there any news from the Jihu and Nani tribes?" ”

Strategist Lu Pukui shook his head and said, "Lord Tusi, there is no news yet, maybe the strength shown by the Han army has frightened the two Tusi of the Jihu and Nani tribes. ”

Nandai Tusi Gongliang Bo sighed and said: "The combat effectiveness of the Han army is indeed strong, we have arranged heavy guards in various mountain cities near the border of the Han State, and as a result, in a few days, more than 50 mountain cities, only three or four mountain cities have not fallen, presumably in another one or two days, the remaining mountain cities will also fall into the hands of the Han army." ”

Strategist Lu Pukui said with a wry smile: "The kind of giant catapult equipped by the Han army is too powerful, and the walls of many mountain cities have been smashed by this giant catapult, otherwise the Han army would not have captured more than fifty of our mountain cities in such a short time." ”

The Southern Dai Tusi Gongliang Bo immediately said: "Now that the Han army is driving straight in, many of our Southern Dai tribes have been captured by the Han army, we must find a way to teach the Han army a lesson, and let the Jihu and Nani people see that the Han army is not invincible." ”

Strategist Lu Pukui hesitated for a moment and said: "At present, the Han army is divided into three ways and has launched an invasion of our Southern Dai territory, if our Southern Dai can eat one of them, then not only will the entire battle situation be completely changed, but it will also be much easier to pull the Kihu and Nani into this war." ”

"Good! Immediately mobilize the warriors of our Southern Dai tribe and eat all the Han troops as much as possible. ”

The target chosen by the Southern Dai people was the road formed by the Southern Xinjiang Legion and the Trap Camp, the Southern Barbarian Legion and the White Pole Soldiers formed another road, and the Longxiang Legion and Wei Wushu formed the last road.

In order to annihilate the Southern Xinjiang army and the trapping camp, the Southern Dai gathered almost seven million people, but the result made the Southern Dai Tusi Gongliangbo extremely depressed, seven million Southern Dai warriors were defeated by less than one-third of their Han army, seven million people eventually withdrew less than two million people, and the remaining more than five million Southern Dai troops, more than three million were killed in battle, and the remaining more than two million people became prisoners of the Han army.

And the Southern Xinjiang Army and the Trap Camp, after this bloody battle of more than ten days, the total casualties also exceeded 500,000, which was equivalent to the loss of one-fifth of the troops, but at this time, the 500,000 Qin Ruishi sent by Liu Ji merged with the Southern Xinjiang Army and the Trap Camp.

In the following months, the army of the Southern Dai tribe fought three major battles with the Han army, and these three wars ended in the defeat of the Southern Dai people, and by the end of April of the 12th year of the Han Dynasty, the territory of the Southern Dai people of more than 20 million square kilometers has fallen into the hands of the Han army, and the more than 30 million men of the Southern Dai nationality have lost almost 20 million, of which about 10 million men of the Southern Dai nationality have been killed, and 10 million men of the Southern Dai nationality have become prisoners of the Han army.

At this time, the Han army participating in this war has reached six legions and five elite troops, the six legions are the Nanban Legion, the Southern Xinjiang Legion, the Longxiang Legion, the Xuanwu Legion, the Gaochang Legion and the Cheshi Legion, and the five elite troops include the Trap Camp, the White Pole Soldiers, the Wei Wushu, the Qin Ruishi and the Beifu Soldiers, and the total number of troops invested has exceeded 15 million.

On the evening of April 29, the 12th year of the Han Dynasty, in the Tusi Mansion of Qingkan City of the Southern Dai Nationality, the Tusi Gongliang of the Southern Dai Nationality asked his confidant Lu Pukui in a hoarse voice: "Are the Kihu and Nani still unwilling to send troops?" ”

Because of the loss of almost 20 million men, the morale of the entire Southern Dai tribe is extremely low, and the Southern Dai Tusi Gongliang Uncle knows very well that if the Kihu and Nani tribes do not send troops, the Southern Dai people will definitely lose in this war.

Strategist Lu Pukui said gloomily: "Lord Tusi, neither the Kihu and Nani are willing to send troops to rescue our Southern Dai tribe, even if our Southern Dai tribe is willing to pay a huge price, the Kihu tribe and the Nani tribe still do not agree to send troops. ”

The Southern Dai Tusi Gongliang Bo gritted his teeth and said: "This group of rat-eyed things, now that the Han State can annex our Southern Dai people, it will annex their Jihu and Nani tribes in the future." ”

Strategist Lu Pukui said bitterly: "Lord Tusi, what should we Southern Dai Clan do next?" Now that our Southern Dai tribe has lost almost two-thirds of the male men, if this war continues, our Southern Dai tribe will be finished! ”

Uncle Tusi of the Southern Dai Nationality was silent for a long time before he spoke: "Send someone to negotiate peace with the Han people, this war, our Southern Dai Nationality can no longer fight." ”

Strategist Lu Pukui hesitated for a moment and said, "Lord Tusi, if you negotiate peace with the Han Kingdom, the conditions proposed by the Han Kingdom will definitely be very harsh!" ”

Uncle Tusi Liangbo of the Southern Dai Nationality said helplessly: "Now our Southern Dai Nationality has nothing else to care about, as long as we can end this war with the Han people, even if we cede all the territories that have been occupied by the Han army to the Han State, it doesn't matter." ”

Soon, the news that the Southern Dai people wanted to ask for peace spread to Canglong City, the capital of the Han Dynasty.

In a palace in the Imperial Palace of Canglong City, Liu Ji asked Zhang Liang, the chief lieutenant of the military department, Zhang Juzheng, the chief lieutenant of the Ministry of Officials, Chen Ping, the chief lieutenant of the Ministry of Rites, Cui Hao, the chief lieutenant of the Criminal Department, Guo Jia, the chief lieutenant of the Ministry of Works, and Xiao He, the chief lieutenant of the household department, "What do you think about the Southern Dai tribe wanting to end this war?" ”

Zhang Liang, the captain of the military department, immediately said: "Your Majesty, the minister thinks that we should not agree to the begging of the Southern Dai people, although there are still tens of millions of men in the Southern Dai tribe, but the morale of the Southern Dai people has been very low, in the face of our Han army, almost defeated like a mountain, our Han should take this opportunity to completely eliminate the strong enemy of the Southern Dai people, so that in the future, our Nanban capital will also be much more stable." ”

Zhang Juzheng, the chief lieutenant of the Ministry of Officials, continued: "Your Majesty, the population of the Southern Dai people captured by our Han army has exceeded 40 million, including 10 million men of the Southern Dai tribe. ”

Chen Ping, the chief lieutenant of the Ministry of Rites, Cui Hao, the chief lieutenant of the Criminal Department, Guo Jia, the chief lieutenant of the Ministry of Works, and Xiao He, the chief lieutenant of the household department, also agreed one after another, and completely annexed the Southern Dai people.

Liu Ji touched his chin and said, "Then convey my will to Han Xin and them, those who commit strong men will be punished even if they are far away!" ”

Han Xin, Lu Xun and other front-line generals, after receiving Liu Ji's will, immediately spread Liu Ji's words "Those who commit strong men will be punished even if they are far away" spread to all the troops on the front line, followed by the Han Dynasty's Nanban Legion, Southern Xinjiang Legion, Longxiang Legion, Xuanwu Legion, Gaochang Legion and Cheshi Legion, as well as the Trap Camp, Baipole Soldiers, Wei Wushu, Qin Ruishi and Beifu Soldiers, like crazy, launched a fierce attack on the remaining territory of the Southern Dai people.

The Southern Dai army, which was already demoralized, almost surrendered in the face of the various armies of the Han Dynasty that had fought chicken blood, and only in Qingkan City, where the Tusi Mansion of the Southern Dai Nationality was located, did they organize a decent resistance.

However, the resistance of Qingkan City only lasted less than ten days, and when the walls of Qingkan City were smashed by giant catapults, the death knell of the Southern Dai tribe, the head of the five powerful clans of the Southern Barbarians, had already sounded.

After the Southern Dai Tusi Gongliangbo was broken by the Han army in Qingkan City, he died in the chaos, and the remnants of the Southern Dai army in Qingkan City, after the death of Tusi Gongliangbo, laid down their weapons and chose to surrender to the Han army.

At the beginning of July of the 12th year of the Han Dynasty, the entire territory of the Southern Dai people was taken into the arms of the Han army, and nearly 70 million Southern Dai people became the people of the Han Dynasty.

The territory of more than 20 million square kilometers of the Southern Dai people was immediately divided into thirteen states by Liu Ji, and all of these thirteen states were assigned to the Nanban Protectorate, which expanded the Nanban Protectorate to twenty-four prefectures, covering an area of more than 40 million square kilometers.

In order to strengthen the strength of the Southern Barbarian Protectorate, Liu Ji then ordered the formation of two new legions in the territory of the Southern Barbarian Protectorate, namely the Yunlong Legion and the Panlong Legion, each of which had ten infantry guards, and the soldiers of the Yunlong Legion and the Panlong Legion, most of whom were surrendered by the Southern Dai people.

In this way, the Han Dynasty had an army of eight million in the Southern Barbarian Protectorate, and the number of legions of the Han army had also increased to twenty.

Liu Ji appointed Peng Yue as the commander of the Yunlong Legion, Sima Yi as the military advisor of the Yunlong Legion, Huangfu Song as the commander of the Panlong Legion, and Zhou Yu as the military advisor of the Panlong Legion.
