200,000 elite soldiers attacked the remnants of Liao, but they were defeated. How unbearable was the fighting capacity before the demise of the Northern Song Dynasty?

During Song Huizong's 25 years in power, although he was addicted to debauchery and artistic creation, he didn't pay much attention to the country's major policies at all, but he was very concerned about recovering Yanyun's hometown. Therefore, at Ma Su's suggestion, he signed a "maritime covenant" with Xu Jin, and joined forces with Xu Jin to attack Liao. The two sides agreed that once the Liao country perished, the Song Dynasty would hand over the old coins originally lost to the Liao country to Jin, who promised to return his hometown to the Song Dynasty.

Song Huizong is obsessed with artistic creation and seldom cares about state affairs.

According to the attack route agreed by the two sides, 8 Jin Army was responsible for capturing Dadingfu in Zhongjing (now Ningcheng, Inner Mongolia) in Liao country, and Song Jun captured Datong Mansion in Xijing, Nanjing (now Beijing). According to the original agreement, Song Jin should send troops to attack Liao at the same time in the second year of Xuanhe (1220), but at this time, the Fang La Uprising occurred in the Northern Song Dynasty, which led Song Jun to pay attention to the domestic battlefield until two years later.

In the fourth year of Xuanhe (1222), Jin invited the Northern Song Dynasty to attack Liao again. At this time, under the extremely fierce offensive of Xu Jinguo, the capital of Liao had fallen into Beijing, and Emperor Tianzuo also fled into Jiashan (now Daqing Mountain in the northwest of Salaqi Town, Baotou City, Inner Mongolia), resulting in no news of him for a long time. In this case, Ye Luchun, who stayed in Nanjing, officially ascended the throne with the support of generals Han Xiao and Ye Lvdashi, and was called the Northern Liao Dynasty in history.

The Northern Liao Dynasty not only governed Yanyun's hometown, but also all his soldiers were defeated by 8 Jin Army, and their fighting capacity was imaginable. Under the leadership of eunuch Tong Guan, those who were ordered to attack Liao just put down the Fang La Uprising, showing a powerful force with a rainbow of morale. In Song Huizong's eyes, the situation that the enemy is weak and we are strong is so obvious. It seems that as soon as the army of Song Dynasty arrives, Northern Liao will fall apart.

In May of that year, Song Huizong sent 100,000 soldiers, with Tong Guan as the commander in chief and Zhongshidao and Xin Xingzong as the generals, and formally sent troops to Xiongzhou for two northern expeditions. But what Song Huizong never imagined was that, under the command of Yelaoshihe (Xiao Gan's works), the seemingly weak Liao army broke out in incredible fighting capacity. First he was beaten in Baigou River, and then he hit Xin Xingzong hard in Fancun.
