The five southern invasions launched by the Jin Dynasty against the Southern Song Dynasty:
1. The Battle of Monk Yuan. One of the important battles in the Song Army's anti-Jin Dynasty war in the early Southern Song Dynasty. Commanded by the famous anti-Jin generals Wu Jie and Wu Lin brothers, they defeated the Jin army in May and October 1131 respectively, stopped the Jin army's western offensive, and protected the gateway to Sichuan and Shaanxi.
2 Battle of Shunchang. It was commanded by Liu Qi, a famous anti-Jin general. The entire war is divided into two stages. The first stage lasted for 6 days from May 25 to June 1, 1140. After three battles, the Jin Army's forward troops were defeated; the second stage lasted from June 7 to June 1, 1140. On June 12, which lasted for six days, Liu Qi led the entire city's army and civilians in a decisive battle with the main force of the Jin army led by Jin Wushu himself, and won the final victory in the defense battle of Shunchang.
3 The battles of Yancheng and Yingchang. It was commanded by Yue Fei, the famous anti-Jin general. This battle was the last decisive battle between Yue Fei and the main force of the Jin army during his lifetime. Soon, Yue Fei was ordered to lead his troops, which ruined the favorable situation in resisting the Jin army.
4 Battle of Zhegao. The Song army commanded by Zhang Jun won first and then lost in this war. After the war, the Jin army retreated to Huaibei and the Song army also retreated to the south of the Yangtze River. The Song court and the Jin rulers signed the humiliating "Shaoxing Peace Agreement."
5 Quarry Battle. The Song army, commanded by the civil servant Yu Yunwen, defeated the Jin army, which prevented the Jin army from crossing the Yangtze River from Caishi to invade south.
