The most tragic defeat in the early Qing Dynasty, Yong Zhengdi's lifelong nightmare, forty thousand troops were wiped out. What happened?

This battle is the Battle of Boketuo Ridge, a war between the Qing Dynasty and Mongolian tribes. Since Gerdan unified Mongolian tribes, the Qing Dynasty has been at war with Mongolia. Kangxi attacked Mongolian tribes in Grdan three times. For the third time, Kangxi finally defeated the Mongolian tribes in Grdan and solved the border problem of the Qing Dynasty. However, Mongolian tribes did not recover. They brought in a new leader and decided to make Alhabo Tan the head of the Ministry of Justice. At first, they obeyed the rule of the Qing Dynasty. When Yongzheng ascended the throne, the relationship between Mongolian tribes and the Qing Dynasty broke down again.

Yongzheng decided to solve the problem of Mongolian tribes by military means. At this time, he actively planned a war and prepared to complete the unfinished business of Kangxi. This time, we must completely solve the problem of Mongols, and they will never get up again. The Qing dynasty also mobilized a large number of troops, led by Fu 'erdan, who went north from Altai. ?

Fourdain, eager to make achievements, found several prisoners and determined that the main force of the Mongolian army was nearby. I didn't expect this to be a smoke bomb released by the Mongols, just to lure Fu Erdan to take the bait. Several prisoners were spies sent by Mongols, deliberately releasing news to Fourdain.

Fourdain led the army to defeat the Mongolian vanguard in Boketuo Ridge. Fu Erdan wanted to pursue the victory and end the war in one fell swoop, but he didn't know that he was on the verge of death. During the pursuit, Fourdain was ambushed and beaten, and the Qing army could only be near Altai Mountain. At this time, the situation deteriorated and the Qing army encountered bad weather. The soldiers' fighting will has reached the brink of collapse, and the Qing army has retreated while fighting. Finally, the Qing army was wiped out, and Fu Erdan became? A man's army? ,
