Emperor Duzong of Song died, and Emperor Gongzong of Song took the throne. Kublai Khan, the ancestor of the Yuan Dynasty, issued a proclamation, counting the crimes of Jia Rudao's detention of emissaries and breaking the covenant, with Boyan Chengxiang as the commander, divided his troops into two routes, sent 200,000 troops, and launched a large-scale attack on the Song Dynasty.
The Yuan army descended yinzhou, Keluoyang, Ezhou, huangzhou, Suzhou, and Anqing, and descended along the Yangtze River. Most of the generals guarding along the river were lü Wenhuan's old subordinates, and one by one they looked down at the wind, and even Jia Xiangdao's henchmen Lü Shikui and Fan Wenhu turned into the vanguard of the Yuan army.
The Song court was greatly shaken and summoned the group of ministers for several days to discuss. The ministers asked Jia Rudao to personally supervise the expedition to save the crisis.
Forced by public opinion, Jia Rudao had to think of himself as the governor of Dadu, and in the late winter, he led all the people and horses to advance by land and water, leaving Lin'an. The Manchu courtiers only hoped that he would repeat a good deed of "rebuilding the society".
A few days later, Jia Rudao arrived in Wuhu, just in time to meet Wang Lixin, the envoy of the Two Huai Systems who had previously written to him accusing him of sitting back and watching the country fall. Jia Rudao thought about the three strategies for saving lives as revealed in the letter, and couldn't help but cry to Wang Lixin: "I don't need to speak out in repentance, until today!" ”
But regret is useless, and fighting is incompetent. Jia Xiangdao was anxious for several days, so the trick was repeated, and then he sent his confidant Song Jing to explain how to do this, so that he went to the Yuan camp to ask for Bo Yan and asked for peace at any cost.
When Song Jing arrived at Yuanying, Bo Yan said, "Now that all the counties along Jiangzhou have belonged to me, what peace talks can be said?" If it is not required and, please Jia Xiang to negotiate! ”
Where does Jia Rudao dare to go to The Yuan Camp? He had to fight with the Yuan army with a hard scalp, and ordered the infantry marshal Sun Huchen and the water marshal Xia Gui to be in front, and lined up to block the Yuan army.
