In mid-May 1181, Zamu made the decision to move farther to the summer pastures, demanding the demolition of the winter camp. As usual, Zamuhe and Temujin marched side by side, leading a long line of followers and herds forward. However, on that very day, Zamu made a fateful decision that he did not want to share the leadership position with Temujin again. Perhaps Zamuhe had realized that Temujin had won hearts and minds among the group, or perhaps he was simply tired of Temujin's existence. He told Temujin that he should set up camp near the hillside, and that Temujin should set up camp near the river, taking only the sheep and goats that were not important. Zamuhe of the White Bone seems to indicate that his power is like that of a horse wrangler, above that of Temujin of the Black Bones, who is regarded as a shepherd.
After receiving instructions from Zamuhe, Temujin retreated to the end of the marching family and livestock procession to seek the advice of his mother, Ha Erlun. He looked confused, confused about how to deal with the situation. However, when Khaelun heard what Temujin had to say, Polti interrupted their conversation, angrily insisting that the relationship between Temujin and Zamuha had broken down and that everyone needed to go their own way. During the night, when Zamuha stopped to camp and rest, Temujin and his few retinue secretly fled, and they continued to move all night in order to maintain the maximum distance from Zamuh and avoid being pursued. By plan or spontaneity, many of Zamuha's men fled with Temujin, taking with them, of course, their own herds. Although this led to the division of the clans, Zamu did not go after them.
In 1189, Temujin, who had been elected head of the tribes, clashed with Zamuhe. The following year, Zamuhe gathered 30,000 men to attack. Temujin divided his 30,000 men into thirteen wings and met them at Tabaal. Although Temujin failed in this campaign, Zamuhe's brutal execution of the captives caused discontent among his subordinates, who turned to Temujin, which only strengthened him.
A few days later, accurate information arrived. Zamuhe had gathered 30,000 horses from thirteen tribes and divided them into thirteen combat units to march towards Lanhu.
Intelligence revealed that Zamuhe's main forces consisted of his own headquarters, the Zata Division, and Temujin's sworn enemy, the Taichiu Division, while the Mongol Tribe's Ulugu and Busy Ubu served as special attack forces. These two tribes, along with the main sons of Temujin's camp, were known as the Mongol triad, and they were both brave and warlike tribes.
Once he had the information, he began to discuss the battle plan with his colleagues. His plan was to emulate the practice of Zamuhe, and since Zamuhe divided his troops into thirteen combat units, he also divided his own troops into thirteen combat units, known as the Thirteen Wings.
The Battle of the Thirteen Wings was an important battle of Temujin (Genghis Khan) during his efforts to unify the steppe tribes of the Mongolian Plateau. At the end of the twelfth century, under the leadership of Temujin, the Mongol beggars grew rapidly, which caused the discontent of the Zataran chieftain Zamuhe. In the first year of Jin Myeongchang (1190), Zamuhe's subordinates plundered Temujin's horses and shot them, and united with 30,000 people from 13 tribes, including Taichiwu, to attack Temujin. After hearing the report of Zamuhe's subordinate Yibelesi, Temujin gathered 30,000 troops and formed thirteen wings (battalions) to meet the enemy. Temujin and his mother Khaelun each unified the wing army, and the rest of the wings were mostly led by the nobles of the Qiyan tribe. The two sides fought a fierce battle at Talan Ban Zhusi (northwest of present-day Wendurhan, Mongolia), but Temujin was defeated and retreated to a narrow strip of land at the upper source of the Nan River (present-day Onen). Zamuhe also led his army back to his headquarters, but he boiled the prisoners in seventy cauldrons, an act that caused discontent among the tribes, who turned to support Temujin. Despite Temujin's defeat, he won the hearts and minds of the people, which allowed his military to recover and grow rapidly.
