In the first decade of autumn, the grassland Hu people, led by the Xiongnu, roared southward and ran headlong into the Dingbian City established by Meng Tian fifty miles south of Yinshan.

There are more than 300,000 grassland Hu people, driving a large number of cattle and sheep, almost one person, two horses or even many horses, led by the Xiongnu head Mandanyu. They had come to travel and make an agreement with the countries of the Central Plains to attack Qin together.

The Xiongnu is actually a name for the Hu people in the grassland in Chinese history, in fact, they call themselves "the country of bears", and the Hu people on the grassland are not all tribes of the huge alliance of "Xiongnu", and the tribes on the grassland are unimaginably numerous.

Chinese history has always been dismissive of the so-called "extraterritorial...... Or if you don't know anything about it, as long as it is the Hu people in the north, they will call it at will, now it is the Xiongnu, and then there will be Xianbei, Turkic, Mongolian or something.

Xianbei has to add quite a lot of Hu people, such as the descendants of Donghu who do not deal with Xianbei.

The Turks are because during the Northern and Southern Dynasties, because the Hu people such as the Tuoba clan and the Qi clan were in power, and their understanding of the Turks was not half-understood and guessed out of thin air (or fabricated), so in addition to the Turks, nomads such as Rouran, Gaoche, and Khitan were also recorded.

The Mongols ......, don't forget how Temujin rose, it was after defeating countless tribes that it strengthened the Mongols, and before that, there were many Chelies, Golden Hordes and the like.

This time, there are quite a lot of tribes who have been summoned to the south by the head man, and almost all the tribes in Mobei and Monan have been gathered, including the Kunxi tribe, the Xiutu tribe, the Lutu tribe, the Okuji tribe, the Lihan tribe, the Xiuchun tribe, the Outuo tribe, and the Xiqi tribe...... Wait a minute.

Many of the tribes convened by the Touman were newly created tribes after the conquest of the Western Regions, and some were tribes from the Donghu side, which developed and grew during the Western Han Dynasty, and until Liu Che launched the "Hundred Years War", the leaders of the Kunxie tribe, the Hutu tribe, and the Lutu tribe were successively kings.

At present, except for the main tribe of the head man, the rest of the tribes are not strong, and at this time the Xiongnu have not yet divided specific official positions, such as the king of Zuoxian, the king of the second Zuogu Li. The so-called "four corners" such as the second right virtuous king, the second right valley liking, etc., will not appear until the Maodun era.

Mao Dun had only fled back from the Yue's side for a long time at this time, and this time Touman did not accompany him when he went south.

Maybe many people don't have an impression, but this time Tou Man Shan Yu led the army south in the history of the genuine version of the opportunity to train 10,000 cavalry, these cavalry were trained as dead soldiers, and it was these people who shot Ming Di in the back, and ten thousand arrows were fired to kill Tou Man.

According to historical records, the total population of the Xiongnu should be between 800,000 and 1 million, and Tou Manshan led 300,000 people to evacuate the population of the grassland. In the history of the original, Meng Tian led the Qin army to fight a fierce battle with the Xiongnu. The Qin army annihilated about 100,000 Huns, so much so that the Xiongnu did not dare to look south for ten years.

Now that history has changed, because the riots occurred prematurely, Qin had to deal with the three kingdoms of Qi, Yan, and Zhao in the Central Plains, the Qiang and Zhuyue in the west, and the southwest had to beware of Lü Zhe's possible attack on Qin, and the forces in Meng Tian's hands were repeatedly compressed, and they were a full two-thirds less than the 300,000 Qin troops in history.

100,000 Qin troops wanted to defend the northern frontier of Great Qin, which was more than 2,000 miles long, and to be honest, it was not enough in any case. It is simply that Meng Tian has built many martial cities, and the prediction that the Huns will launch from the direction of Yinshan is also correct.

300,000 Huns went south out of Yin Mountain, and when they crashed into Dingbian City, it seemed a little inexplicable.

Why is Touman inexplicable? It was because before this the Huns and the Yueshi fought a great war, and all their energy was involved in the west. In the east, only some tribes were nomadic, and they did not pay much attention to the movements of the Qin state.

It seems hasty to invade the south without doing any intelligence spying, right? But this is in line with the truth, the current Xiongnu do not have specific official positions, and are still the classification of tribal leaders, elders, big leaders, and small leaders in the form of barbarians. Can we expect such a system to have a clear division of labor?

Dingbian City was built very well by Meng Tian, because it was a city guarding the first line of defense, and it took an angular shape modeled after the construction of Lu Zhe. The height of the city wall is about three zhang, and in addition to the bed crossbow arranged on the city wall section, the hanging knife and rolling stone system learned from the defense system of Nanling City are also equipped with a lot.

It can be said that Dingbian City, which has 8,000 Qin troops, has a lot of urban defense facilities except that it has no moat. In addition, there are two miniature versions of Dingbian City on both sides of Dingbian City, each with a thousand Qin troops, and the three cities have become a corner.

The Huns were stunned when they were blocked by the city, they remembered very well that two years ago this was a flat land, and they did not understand how three cities could appear in two years.

It is also said that because of the limited productivity of the times, it is not so easy to build a city within two years, but the Qin State has not only built one city, but three cities one large and two small.

The city blocking the way looked much smaller than the traditional Chinese city, but the Huns immediately understood that a small city did not mean that it was easy to fight.

The southern invasion of the Xiongnu had been informed by the Qin State three years ago, and it had been preparing for three years in order to fight the Xiongnu against the Qin State, but the previous main attack had become a passive defense.

To be honest, the Qin people did not lack nomadic population, and they would not suffer at all in the form of guerrilla warfare in the form of counterattack on the grassland, and in many cases they could even rely on the advanced nature of civilization to fight the grassland Hu people all over the place.

The Qin army is even more handy in a defensive war, after all, their ancestors have grown up in this form of warfare for generations, and they are facing the grassland Hu people who have no siege skills, although they are in a huge gap in strength, but they still seem to be at ease.

For a whole month, the 300,000 Hu people led by Touman besieged the three cities with Dingbian City as the main defense system, and they couldn't capture it at the cost of about 20,000 people for a month, which made them begin to have a kind of irritability.

A tribal leader from the west, called the guy from Juci, built yì and directly bypassed the Qin army's city, which was difficult to capture, and the army rolled south and went straight into Qin.

Of course, it is correct to build such a construction with the goal of not occupying the land, but the Xiongnu did not go south this time to rob, they agreed with Qi, Yan, and Zhao to attack the Qin State, and the Xiongnu would get the Heshuo region and the upper and northern counties of the Qin State.

Wars aimed at capturing land require defeating the enemy's army and inflicting more likely casualties in order to preserve the results after victory. Moreover, with such three cities behind them, even if the Huns did not rely on logistical supplies, it would be too dangerous to have an enemy army behind them.

There are also some that Touman did not say clearly, the distance between the Xiongnu on the grassland and the Central Plains countries is too far, and he doesn't know what the war situation in the Central Plains is at all.

It was about the second month of the Xiongnu's siege of Dingbian City, Meng Tian led 50,000 Qin troops to the north, and he did not take another step north after advancing the tribe to the second line of defense, but made a division of troops to send 50,000 Qin troops to various Wucheng reinforcements, but the first line of defense did not send even a single soldier.

Meng Tian was definitely not dizzy when he did this, the Huns were very mobile, and any increase in troops on the first line of defense during the battle was to send troops to the Huns to eat.

The first line of defense has played a role in blocking the Xiongnu roaring south, as a commander, Meng Tian is not only thinking about the life and death of the Qin army in the first line, but also how to use the defense line to resist layer by layer, and at the same time to wear down the morale of the Xiongnu army and wait for the appearance of fighters.

After all, no matter how good the city's defense system is, it is a soldier to operate them, and once the soldiers are not replenished, it will definitely cause a shortage of manpower. When there is a shortage of manpower on the defending side, there is also a gap in the city, not to mention the demoralization caused by repeated hard battles.

The Huns did not have many siege methods, but their numbers were too many, and under the attack of the later rotation day and night, the satellite city on the left side of Dingbian City fell. On the third day when the satellite city on the left was breached, the satellite city on the right side of Dingbian City was also breached.

The satellite cities that are the momentum of the horns have all been lost, and how can the remaining 3,000 defenders of Dingbian City not understand that their end is coming? Under the siege of the Hu people, and on the premise that the Hu people were nomads, the three thousand defenders, from a partial general to an ordinary soldier, knew that there was no possibility of breaking through.

Dingbian City fell, it held out for fifty-seven days when it was broken by the Huns, Meng Tian learned that the fall of Dingbian City was not someone to tell him, but the distant north of the sky-rushing fire to tell him that Dingbian City no longer exists.

Yes, they couldn't hold it and couldn't break through, and the defenders of Dingbian City chose to set fire to the city after the city was broken, and they let nearly 10,000 Huns bury them for their ends.

The Qin people endured the war, and the Qin people did not hesitate to kill themselves in the face of the national tragedy, but this is not the only reason why the first line of defense of the Qin army was wiped out by 10,000 soldiers, the real situation is that they did not know that there would be no reinforcements at all, and after knowing it, they could only fight desperately, and when they fought to the point that it was impossible to escape and survive, they were taken by a few people to burn the city with a jade stone.

Meng Tian did not shed a single tear for the annihilation of the 10,000 defenders in front of him, he did not have time to shed tears, because after the fall of the first line of defense, the Huns would soon approach the second line of defense.

In the history of the Qin State, how will the 10,000 Qin troops in Dingbian City and satellite cities be recorded? It is definitely a record of the beauty of this 10,000 Qin army, their death in battle was out of the great sentiment of voluntariness, and then the big book about how brave they were in the face of the invasion...... (To be continued......)
