Historically, due to the surrender of the Karaqin tribes at the turn of the spring and summer of the first year of Chongzhen, after the end of the Dongjiang Campaign, Huang Taiji personally led the army to participate in the alliance of the tribes on the south bank of the Narit River, that is, in Jiri Garangtu, and after the alliance, he personally led tens of thousands of troops to the west to investigate the Har Department Lin Dan Khan, and Lin Dan Khan from Chahanhot (Erenhot), completely drove to the naturalized city that originally belonged to Tumut Jinong to live in herds.

This naturalized city was later known as Hohhot.

In this way, Huang Taiji not only completely recovered the heart of the Eastern Mongolian tribes, but also led Lin Dan Khan, who was always unclear about the situation and made enemies everywhere, to the west, so that the border pressure on the entire trilateral region of Shaanxi in the Ming Dynasty suddenly increased.

Because of the continuous westward migration of Lin Dan Khan of the Chahar Department, it caused a series of chain reactions.

The arrival of Lin Dan Khan of the Chahar tribe forced the Tumut tribe to migrate westward, gradually crossing the Yellow River and entering the Hetao region, which originally belonged to the Ordos tribes, so the Ordos tribes had to move westward as well.

As a result, the northwest, which had been peaceful and uneventful, suddenly became chaotic, and the so-called trappers continued to attack in the direction of Ningxia and Gansu, while Ningxia Town and Gansu Town, which were unknown, just blindly relied on the Great Wall to block and intercept along the way.

Historically, this kind of offensive lasted until the Chahar Department moved westward to the Qinghai Plateau, and the armies of the towns on the three sides of Shaanxi were exhausted in the face of this offensive that lasted for many years, and as a result, the thieves who could have been exterminated also took the opportunity to take advantage of it.

And because of the westward migration of the Tumut, Ordos and Chahar tribes, the Ming Dynasty spent a lot of financial and material resources to consolidate the western defense line, but the result made the thieves dare not go west, and finally caused chaos in Shaanxi, Henan, and Hu, and then the situation in the interior of the entire Ming Dynasty became out of control.

All of this, if the initial contributing factors can be traced back to the source, is the attachment of the Karaqin tribes to the Houjin. And all this, in this time and space, no longer exists.

At the turn of the spring and summer of the first year of Chongzhen, the Karaqin tribes, with the support of the Ming Dynasty, not only survived the cruel spring famine, but also subdued some small tribes in the southern part of the Mongolian right wing or the southern part of Eastern Mongolia that did not have time to move west with Chahar.

In addition to the Ao Han and Naiman tribes, which were close to the eastern border wall of Liaodong, most of the areas north of the Great Wall of Xuanfu and Jizhen, west of the border wall of Liaodong, and south of the Xilamulun River were now the territory of the Karaqin tribes.

It was precisely because of the absence of the Karaqin tribes that the alliance of the tribes of Narit did not have the attraction in history, so Huang Taiji did not personally lead the army to come.

At the same time, before he completely conquered the Eastern Mongolian tribes, Huang Taiji did not dare to drive 2,000 miles straight to Chahanhot.

And if it was simply to conquer the Karaqin tribes, Huang Taiji felt that there was no need to go out in person. Therefore, the alliance on the banks of the Nerit River in September of the first year of Chongzhen was like a child's play from beginning to end.

The Tiancong Khan of the Later Jin Jurchens did not participate, the co-leader of the Brain Wen Horqin tribes, Tushetu Khan Oba, also thought that he had no need to participate, and the leader of Alu Korqin, Chegen Khan Dalai Chu Huer, did not think that he needed to lower his status to participate in a meeting chaired by the left-wing Taiji of Brain Wen Korqin.

As a result, despite the blessing and endorsement of the Houjin envoys, it seemed that the day of the alliance was approaching, but only the right wing of Horqin, Taiji Kongol, the leader of the Ao Han tribe, Sonomu Duling, the Naiman tribe, Taiji Dorji, the Zalut tribe, Taiji Zabu Morgan, the Bahrain tribe Taiji Angkun, and the Ongniute tribe Sonomu Nayan, each led their headquarters to Jiri Galangtu on the south bank of the Nerit River.

The leaders of the various departments or the men and horses brought by Taiji, more than 1,000 horsemen, less than 300 horsemen, just like that, when the day of the alliance came, Taiji Zhaisang of Horqin on the left flank took out all his old books, and finally barely got together seven or eight thousand horses.

On the day of 9 September, on a platform in Jirigalangtu, the left-wing Korqin Taiji Zhaisang, who was nearly 50 years old, accompanied by the Later Jin envoys Yanguli and Darhan, ascended a high platform prepared in advance and swore an oath with the leaders of the various tribes who had influenced the Later Jin and Horqin to come to participate in the pledge of the alliance, such as Korqin's right-wing Taiji Kongor, the leader of the Ao Han tribe, Sonomu Duling, the Naiman tribe's Taiji Dorji, the Zarut tribe's Taiji Zabu Morgan, the Bahrain tribe's Taiji Angkun, and the Ongniute tribe's Sonomu Nayan.

Horqin's left-wing Taiji Zaisang, in a solemn and slightly sad tone, said: "Immortal Heaven is above, and today your people, Zaisang, the son of Manggusi of the Horqin Borzigit clan, ask for your generous care. In the spring of this year, your loyal people, Gonchuk of the Ao Han tribe and Wu Keshan of Horqin, with infinite kindness and reward, went to Karaqin to comfort your people, but not only did they not receive the hospitality they deserved, but were despicably and cruelly murdered by the Taiji Burhatu of Karaqin and the strangers. O fair and strict immortal heaven, please uphold justice for your loyal people, the Korqin and Ao Han tribes, so that the Burhatu of Karaqin will be punished as it deserves! ”

After saying this, Zaisang's other two sons, Chahan and Manzhu Xili, led a white horse and a black ox to the high platform.

At this time, Zaisan looked around at the other tribal leaders standing on the high platform, and then said: "Immortal Heaven is above, and your most loyal people today, Horqin Left Wing Taiji Zaisang, hereby sacrifice to you, and swear as follows. ”

Horqin's right-wing Taiji Kongor, the leader of the Ao Han tribe, Sonomu Duling, the Naiman tribe Taiji Dorji, the Zalut tribe Taiji Zabu Morgen, the Bahrain tribe Taiji Angkun, and the leader of the Ongniute tribe, Sonomu Nayan, and others, also learned to say their names one by one, and then followed Jaisang and said: "We will be like the five fingers on the palm of our hands, closely united and sent troops together to avenge the Gonchuk of the Ao Han Department and Wu Keshan of Horqin, as well as other innocent and tragic deaths."

"Thou shalt slay all the chiefs of the Karatham and put to death their servants, and plunder their cattle and flocks, and divide up their riches, and their women, and their pastures. If you don't destroy Karaqin, you will never withdraw your troops, and if you violate this oath, there will be such an arrow. ”

While the people were saying these words, each of them had an arrow in his hand, and when he said this, he broke the shaft of the arrow in his hand at the same time. This is a kind of poisonous oath of the Mongolian tribes.

The crowd broke the shaft of the arrow in their hands, and then listened to Taiji Jaisang of Horqin's left flank continue: "Immortal Heaven is above, and today your most loyal people, with a white horse and a black ox, sacrifice a white horse and a black ox, please accept this insignificant gift!" On the day of the destruction of Karaqin, your most loyal people will sacrifice to you with the head of Burhatu, who dared to transgress the immortal heavens! ”

After saying these words, Jaisan and Kongol drew their swords from their waists, one holding the white horse and the other holding the black ox, and stabbed the heart of the sacrifice they were leading.

In an instant, the white knife went in, the red knife came out, and the blood gushed out, and soon flowed all over the ground on the entire high platform, and the white horse and the black bull fell to the ground screaming, struggled for a while, no longer moved, and died.

At this time, the entire oath ceremony was completed, and the Eastern Mongolian coalition army, dominated by the left-wing Horqin or Narit Korqin, was officially formed.

Because the Mongolian tribes of this era still attach great importance to the oath made in front of the immortal heaven, there are few times when they break the oath of alliance.

Therefore, as soon as the oath of Jiri Galangtu was completed, the envoys of the Later Jin, Yanguli and Darhan, despite the repeated retention of Zhaisang and Kongguoer, left Jiri Galangtu at noon on the same day, and quickly returned to Shenyang, the capital of the Later Jin, to report the good news to their master Huang Taiji.
