After the demise of the Liao Dynasty, the supreme ruling clique of the Jin Dynasty saw through the political decay and military incompetence of the Northern Song Dynasty from the performance and negotiation of the Northern Song Dynasty's war against Liao, and then won the victory and invaded the Northern Song Dynasty. In the seventh year of Xuanhe (1 125), our army was divided into two groups, headed by Wan Yan Han Zong, and attacked Taiyuan from Yunzhong House. The East Route Army was led by Wan Yan Wang Zong, and Pingzhou made progress in Yanshan Prefecture.
After the two roads agreed to capture Taiyuan and Yanshan Mansions, the East Route Army entered Kaifeng at the gates, leaving Tongguan and Luoyang in the north and crossing the Yellow River to Tokyo in the south. In Taiyuan City, the marked army was stubbornly resisted by Song Jun soldiers and civilians led by Wang Bing and failed to capture for a long time. When the East Route Army arrived at Yanshan Mansion, Song Shoujiang Guo surrendered, so nomads marched and crossed the Yellow River to March to Tokyo.
After hearing the news of nomads from the south, Song Huizong did not dare to take the responsibility of leading the enemy personally, and quickly passed the throne to Prince Zhao Huan in an attempt to escape from the plight of the south. Zhao Huan acceded to the throne for Song Qinzong, and changed the following year (1 126) to the first year of Jingkang. At this time, officials and people in the ruling and opposition parties exposed the sins of six thieves, including Cai Jing, Wang Fu, Tong Guan, Liang Shicheng, Li Yan and Zhu Cuo, and demanded to be put to death. Song Qinzong was forced to exile or behead Cai Jing and others.
In the first month of the first year of Jingkang, forced by the situation, Song Qinzong used the hawkish Li Gang to personally expedition and deployed the Beijing defense. Li Gang arranged the garrison facilities in Beijing and launched a fierce attack on Xuanzemen, Kaifeng, when Hong Yan Wang Zong led Jin Jun Enemy at the Gates. Li Gang organized Kaifeng soldiers and civilians to hold the city, fought fiercely with 8 Jin Army, and repelled 8 Jin Army who besieged the city.
Seeing that Kaifeng was difficult to capture for a while, Wan Yanzong adopted the strategy of discussing peace and war. Song Qinzong was originally a bad king who was afraid of war, so he quickly sent messengers to Jin Ying to make peace. Hong Yan proposed that Song paid 5 million taels of gold, 50 million taels of silver, cattle 10000, camels10000 and motley satin 100000, and ceded the three towns of Taiyuan, Zhongshan and Hejian, honoring them as uncles and taking Prince Song and Prime Minister as the hostages.
Desperate, Song Qinzong fully agreed to Hong Yan Wang Zong's harsh demands, and ordered to borrow gold and silver in Kaifeng City and deliver them to 8 Jin Jun. Li Gang resolutely opposed making peace with 8 Jin Jun, so Song Qinzong held Li Gang responsible for the failure of Song Bing's night attack on Jin Ying, ordered Li Gang to be removed, and abolished the personal expedition royal battalion company presided over by Li Gang to express his determination to make peace with Ren Jin.
Song Qinzong's perverse behavior aroused the indignation of Kaifeng soldiers and civilians. Too many students, such as Chen Dong, wrote in Xuande Gate, demanding the reuse of Li Gang and the recall of Li Bangyan and Zhang Bangchang who advocated peace talks. Tens of thousands of people came to the front of the temple in unison to support and support Chen Dong, demanding that Song Qinzong accept him, smash Deng Wen's drum and kill dozens of eunuchs.
Song Qinzong had to announce the reuse of Li Gang, a right-handed minister, and let Li Gang preside over Beijing's four-sided defense. At this time, about 200,000 people from Wang Bing, a frequent visitor to the Song Dynasty, arrived one after another. Faced with this situation, Hong Yan Wang Zongshen knew that it was difficult to capture Kaifeng with only 60,000 soldiers and horses, so after Song Qinzong agreed to cede the three towns, he left Kaifeng and returned to the north in February of the first year of Jingkang (1126th).
Looking back at the north, Hong Yanzong's battle in Hebei was temporarily calm, but the war in Hedong continued to be tense. From February to July of the first year of Jingkang, Song Jun invaded Taiyuan three times, with a total of 400,000 troops, all of which were defeated by 8 Jin Army, and the main force of Song Jun was exhausted. The temporary calm in Hebei and the stalemate in the war in Hedong are only the intermission of the larger invasion of 8 Jin Army.
However, the decadent ruling group headed by Song Qinzong thought it was peaceful. Just lifted the relieving of the prestigious veteran Zhong Shidao, and the loyal soldiers who came from all walks of life were also sent back, and Song Ting returned to his gentle and playful old style. The pacifists regained the upper hand in the imperial court. In June of the first year of Jingkang, Song Qinzong hated Li Gang's repeated remarks, borrowed money from Taiyuan, sent him as a special envoy to Hedong and Hebei, and forced Li Gang out of the court. In August, Li Gang was dismissed as an ambassador to the two rivers because of his failure to aid Taiyuan.
In August of the first year of Jingkang, 8 Jin Army took a rest in Xia Hou, and invaded the south again on the pretext that Taiyuan, Hejian and Zhongshan were inferior to the Song Dynasty. Hong Yan Han Zong and Hong Yan Wang Zongchao went in two directions: East and West. At this time, Wang Bing, the general of the Song Dynasty, had been sticking to Taiyuan for more than eight months, but he was defeated on September 3rd due to lack of food. Hong Yan and Han zong pushed south to Heyang on the north bank of the Yellow River. At the beginning of October, the East Route Army of Wang Zong of Hongyan also captured the town of Calm House in Hebei. Yu Jun's invasion to the south destroyed the situation in the Northern Song Dynasty.
