What was the Mongolian-Song War in the period of Emperor Taizong and Xianzong?

Mongolians' understanding of the Southern Song Dynasty originated from the Jin Dynasty. They called the Southern Song Dynasty "Southern Family Thought". After Genghis Khan rose in the north, the main target of the attack was naturally the ruler of the suzerain country. When he was fighting Jin, he sent an envoy to make peace with the Southern Song Dynasty. In the 13th year of Genghis Khan (11th year of Jiading, Song Ningzong, 12 18), Gebuhan was sent to "make peace with the Song Dynasty" for the purpose of making friends with the Southern Song Dynasty and seeking Jin State. At first, the Southern Song Dynasty was indifferent to Mongolia's initiative, but after being forced to move south by Mongolia's military pressure, the Jin Dynasty tried to make up for the losses in the north by cutting the Southern Song Dynasty, and the Song and Jin Dynasties went to war. So someone made suggestions on "Beitong Tatar". 16 years (11th year of song Jiading 122 1), Gou Jian in the Southern Song Dynasty went to the Western Regions as an envoy, and at the same time, in the name of Jia She, the envoy of Huaidong, sent Zhao Gui to visit a man named Muqali in front of the Mongolian army in Hebei. In the 18th year (16th year of Song Jiading 1223), Gou went to Mongolia for the second time, and the two sides may have discussed the issue of joint destruction of gold. The old trick of destroying Liao in the Song Dynasty was repeated, and Genghis Khan's strategy of destroying gold in the Song Dynasty achieved initial results.

Twenty-two years (the third year of Baoqing, Song Lizong 1227), Genghis Khan sent a Mongolian army into Lizhou Road in the Southern Song Dynasty in the name of taking gold for summer vacation, and conducted armed exploration to understand the military deployment of the Southern Song Dynasty and the terrain danger of Longshu area. In the Song Dynasty, Sichuan asked Zheng Dama to abandon the five states outside the customs, and the Mongolian army retreated after plundering the five states of Tieji, Fenghuang, Hecheng and Tianshui. Genghis Khan used the feud between Song and Jin Dynasties and the circuitous outflanking strategy of destroying Jin Dynasty in Southern Song Dynasty.

In the third year of Emperor Taizong (the fourth year of Song Shaoding, 123 1), in the first month, Tuo Lei sent envoys to the Song Dynasty and put forward two demands: borrowing roads and needing food. Gui Ruyuan, the appeaser of Sichuan in the Song Dynasty, made a compromise, hoping to meet each other's conditions in exchange for border peace, and made a decision to give up the five prefectures and keep the three customs, so that Hanzhong could learn cattle and wine, and sent people to Fengxiang Mongolian camp to return. At the same time, Donglu also sent Li Bangrui into the Song Dynasty, hoping to "fake Huainan to prosper Henan". In March, Tuo Lei entered the Song Dynasty through three passes and occupied Fengzhou, Yangzhou and Xingyuan. In May, it was not uncommon for Song to kill messengers. 10, the Mongolian army launched an attack on Song, and even passed three levels. Because the purpose of this military operation was to cut gold by the way, the Mongolian army left the territory of the Song Dynasty after the Guanghua army crossed the Hanshui River in December, which was the third confrontation between Mongolia and the Song Dynasty before the outbreak of the War to Destroy the Song Dynasty. These three military conflicts are the prelude to the Mongolian-Song War. Since then, Meng and Song reached an agreement to destroy the gold together. After the demise of the Jin Dynasty, the Mongolian army stationed troops on both sides of the great river, starting from Cao (now Heze, Shandong Province) and Pu (now Juancheng, Shandong Province) in the east and reaching Qin (now Tianshui, Gansu Province) and Long (now Longxian County, Shaanxi Province) in the west to prepare for the Song people. General Su Butai "increased the number of villages and ambushed in Shaanxi and Tongguan" to prepare for the remnants of the Jin Dynasty that still existed in Qin and Gong (now Longxi, Gansu).

In the agreement to jointly destroy the gold, the two sides "take Chen (now Sui County, Henan Province) and Cai as the boundary", and after the gold was destroyed, "Chen and Cai returned to northwest Mongolia"; The counties occupied by the Southern Song Dynasty, such as Si (now Xuyi, Jiangsu), Hao (now Hao County, Anhui), Su (now Anhui), Cai, Tang (now Tanghe, Henan) and Deng (now Dengxian, Henan), were returned to the Song Dynasty. In this joint action, Song Fang has gained unprecedented benefits. After years of war, the Mongolian army needed to rest and formulate a new national policy, and did not attack Song. There was a brief period of peace between the two sides.

The rare victory inspired the monarch and subjects of the Southern Song Dynasty. Advocated by some leading generals, Song Lizong, who was eager for recovery, brazenly decided to take up troops in Henan and recover the three capitals, so as to reach the goal of crossing the river with Mongolia.

In June of six years (the first year of Duanping in Song Lizong, 1234), Song Jun started construction. On July 5, the man died. On the one hand, Mengjun decided to prevent Song Jun from going north by releasing the river; on the other hand, it ambushed Shaoma and Zengtun in Sanjingguangbu, and at the same time voluntarily withdrew from Xijing Luoyang to lure the enemy with an empty city. In July, Song Jun, who didn't receive his salary, was urged by Zhao Kui who stayed in Tianfu, Nanjing and Huaidong. When Song Jun's vanguard troops entered Luoyang, Mongolian troops stationed in Longmen, south of Luoyang, were pre-deployed, allowing them to enter an empty city, which was exhausted by their veterans and self-defeating. And attack its follow-up troops with elite soldiers. Song Jun was besieged, and most people drowned in Luoshui or were killed by Mongolian troops. When the Mongols returned to attack the city, Song Jun was killed, and nine out of ten of the dead were killed. After the Mongols occupied Luoyang, Song Jun had to give up Bianjing and return. Song Jun's action to recover the three capitals ended in complete failure. Its direct influence was that it first destroyed the agreement between Mongolia and the Song Dynasty and provided an excuse for Mongolia to launch a large-scale war against the Song Dynasty, which was "the fuse and starting point for the outbreak of the Song-Mongolian war".

In autumn, the king of Mongolia will discuss the matter of cutting the Song Dynasty and make strategic arrangements. In December, according to the usual practice, Wokuotai sent Wang Xie to the Song Dynasty, demanding that the Southern Song Dynasty serve Mongolia with gold as a gift, which was rejected, so he succeeded to the throne with the army.

The first stage of the Mongolian-Song War was from the sixth year of Taizong (the first year of Song Duanping 1234) to the first year of Xianzong (the tenth year of Song Lizong 125 1). The war was fought on three battlefields, East and West.

General Asura was in charge of the East Road, with Zhang Rong as the pioneer, and went out to Heluo, focusing on attacking Xu (now Jiangsu) and Pi (now Jiangsu).

In the middle of the road, the three sons of Wokuotai came out, and all the kings were bald and warm-spoken. The Tass society led them out of Tang and Deng, focusing on Xiang and Fan (now Xiangfan City, Hubei Province). West Road, led by Khan's second son, Kuo Duan, focused on attacking Qin Gong and Bashu.

In the seventh year (the second year of Song Duanping 1235), the Mongolian army led by Guo Chu passed through Jinzhou (now Ankang, Shaanxi), Guanghua (now Guanghua West, Hubei) and went down to Hanshui. I don't want to spend too much time leading troops south from Tang and Deng. In September, I went to the Han Dynasty and entered the Han Jing area. Zhao Xiang, the governor of Dengzhou in the Song Dynasty, fell, and the Mongolian army went down to Zaoyang again to concentrate on attacking Xiangyang. Song Jun insisted on turning to Suizhou (now Suixian, Hubei) and Yunzhou (now Zhongxiang, Hubei). The following year, Li Boyuan, commander-in-chief of Xiangyang in Song Dynasty, fell, and the Mongols captured Xiangyang. Counties north of Jiangling (now west of Hubei), Fang (now Hubei), Sui, De 'an (now Anlu, Hubei) and Ying were all captured by Mongolian troops.

Eleven years (Song Lizong jiaxi three years, 1239), Song Jun recovered Xiangyang. Mongolian troops reinforced from Sichuan and Sichuan to stop General Song. Because poison Shuai Kuo died in 1236, Xiangyang was recovered by Song Jun, and the middle battlefield could not progress, so the Mongolian army recruited soldiers and civilians in Hunan, Fan, Sui and Xinyang.

1235, Mongolian troops led by Wen Buhua entered Huaixi under the cover of Guangjun. /kloc-in the winter of 0/236, the Tass news agency went south from Dengzhou and attacked Qi and Huang. Zhang Rou stationed troops in Cao Wu (now east of jingshan county, Hubei Province) and captured Jiuliguan (now northeast of Xiaogan County, Hubei Province). Soldiers were stationed in Changfeng Ridge in the north of Cao Wu. They worked tirelessly to clear the way for the army to attack Huaixi and open up the Jianghuai battlefield.

1237, Gwangju (now Huangchuan, Henan Province) was occupied without oral temperature, and Huangzhou (now Huanggang, Hubei Province) was not occupied, seeking the Yangtze River; Shixia Fuzhou (now Tianmen, Hubei); Tower to the southeast; Another army arrived in Hefei. Without spending enough time, qi zhou (now Qichun, Hubei Province) and Zhou Shu (now southwest of Lujiang County, Anhui Province) fought fiercely in the Yangtze River and Song Jun. After the defeat, he turned to Huangzhou, and Song held on. After a desperate battle between the army and the people, the Mongolian army could not attack for a long time and retreated. This is Song Jun's first great victory since the Battle of Mongolia and Song Dynasty. Later, Song Jun was defeated in Anfeng, and the Mongolian army suffered heavy losses and moved northward.

1August 235, Tahai led an army to attack Hechi from Fengzhou, and even went down to Guanwai, Chengdu, Xicheng and Mian. In October, Wang Shixian, the cheap general manager of Jin, led the remaining soldiers of Jin to surrender and ordered them to follow him into Sichuan. Wang Shixian ruled dozens of counties, winning tens of thousands of soldiers, and was known as Qin and Gong Zhihao. Familiar with the road into Sichuan and the area around Sichuan, and make friends with the 18 departments of Uighur and Xixia. His surrender strengthened the strength of the Mongolian army to attack Sichuan. After attacking and pulling the strongholds near Shu,1August, 236, Kuo Duan took Tahai as the marshal and Wang Shixian as the pioneer, and led the armies of Mongolia, Xixia, Jurchen, Hui, Tubo and Bohai Sea, claiming to be 500,000, to attack Shu on a large scale. Enter Sanguan, reach Wuguan, and occupy the apricot garden. Jinniu Road attacked the Sichuan army and fought fiercely with Song general Cao Youwen in Yangpingguan. After Cao Youwen ambushed and defeated the army that reinforced Da 'an in the Southern Song Dynasty, Wang Shixian and dispatch troops met the tower navy that attacked Yangpingguan. When Cao Youwen died, the Mongols opened the Shu Gate and Song Shoujun fled. Kuo Duan was divided into two groups and pushed them into Chengdu. A route led by was from (now northwest of Wenxian County, Gansu Province), bypassing Jiange West and reaching Chengdu directly. Kuo Duan led himself all the way out of Lizhou and Jianmen to meet Chengdu.

In September, Kuo Duan captured Daan from Hanzhong. In October, its pioneer Tubo general Zhao Agpan entered Chaotian Pass (now 60 miles north of Guangyuan City, Sichuan Province), occupied Lizhou, and divided his troops into Langzhou, Shunqingfu (now Nanchong City, Sichuan Province) and Tongchuan. In mid-June, all armies will join forces near Chengdu. After a long time in Chengdu, Mongolian troops entered the city, officials looked in all directions and residents looked in all directions. When it was discovered that the newcomers were Mongolian troops, the whole city immediately fell into chaos. Ding Fu, the deputy envoy of the Song Dynasty, refused to escape, assembled soldiers and put all his eggs in one basket. In the end, because they were outnumbered and died in the battlefield, the Mongolian army occupied Chengdu. After the Colombian army entered Wenzhou, Motianling was blocked one after another. After more than two months, Fang and Fang met in Hanzhou (now Guanghan County, Sichuan Province).

After occupying Chengdu, we divided our troops and raided Meishan, Qingshen, Jiading (now Leshan), Qionglai (now Qionglai), Shu (now Chongqing), Peng (now Pengxian), Han, Jianchi (now Jianyang), Yongkang (now guanxian), Tong (now three) and Sui (now Sichuan) in Sichuan.

1239, Tahai and Wang Shixian captured Dongchuan, once attacked Kuizhou (now Fengjie, Sichuan) and Enshi (now Enshi, Hubei) and pushed eastward. In the Southern Song Dynasty, emergency troops were deployed to reinforce Sichuan, and the Mongolian army retreated. 1240, the Song Dynasty sent Yu Gong as Fu Xuan's special envoy to Sichuan, and learned about Kuizhou, and Sichuan's defense improved slightly. The appeasement system allowed Chen Jiangzhi to repair the city wall and decorate the defense of Chengdu and Hanzhou. 124 1 year, Tahai and others went to Chengdu, and Chen Jiangzhi was captured and killed. Peng Daya, the deputy envoy, managed Chongqing, built a city and a village in Yushan, Hezhou, to shield Chongqing. 124 1 year, Wokuotai died. Since then, Manet Zhen Shi did not have the ability and enterprising spirit to govern the country, and did not make significant progress in the Song War.

Manet was in Zhenguan for two years (Song Chun for three years, 1243). Yu Jie was appointed as Sichuan appeasement ambassador in Song Dynasty. Yu Jie set up Marshal House in Chongqing, and led Sichuan military and civilians to build and expand more than 20 mountain cities of various types. Based on mountains, stationing troops to collect grain strengthened Sichuan's defense.

In the second year of Manet and the first year of Dingzong (the sixth year of Zhezong, 1246), the Mongolian army attacked Jiading and entered Shu on the fourth road, all of which failed. Yu Jie began to fight back against the Mongols. After the reign of Emperor Dingzong, Houhai fell for two years (Song Chun occupied 10, 1250), and Yu Yu made a northern expedition to take Hanzhong. Yu Jie took Jinniu Road and headed for Hanzhong, winning three out of three. The next year, he led various armies, claiming to be 100 thousand, to attack Hanzhong. The ancient ancient gulong belt in Yuanxing province of Mongolia was held by the Mongolian-Chinese army with less than 5,000 people, but Song Jun repeatedly failed to attack. Later, Mongolian reinforcements arrived and Yu Jie retreated.

125 1 year, Xian Zong Mongo ascended the throne, and after dealing with the power grab disputes within the gold family, he made arrangements to conquer various places. The Mongolian-Song War entered the second stage.

When Mongolia arranged military conquest, he ordered Chahan and Necole Liu to unify the Mongolian and Han armies. Bring a son to unify the Mongolian and Han armies in Sichuan and other places; Mongolian and Han armies in Tibet and other places, such as Helijie, "are still advancing." Kublai Khan, the younger brother of the emperor, presided over the military affairs of South Mongolia and the Han Dynasty. Kublai Khan widely listened to the opinions of Confucian officials and generals in the Han Dynasty and helped Khan formulate more aggressive policies. While deploying military tasks, he paid more attention to solving the problems of food and military pay, and established garrison bases along the border. On the Bashu battlefield, Wang Dechen, a cheap coach who works as a regular worker, rebuilt Mianzhou City and set up a government office as a base for going deep into Sichuan. The development of wasteland in Bailong River area and the inclusion of soldiers in agriculture cut off the door for Song people to move northward and laid the foundation for Sichuan to use troops. On the battlefield of Jingxiang, Yao Shu's suggestion was adopted: "Soldiers who go to Qiu Lai in spring are divided into important areas, and they will fight when they arrive, and they will plow when they go, and the food is high." Side preparation is both solid and aggressive. "On the battlefield of Huaibei, Zhang Rou was ordered to move to Bozhou, build roads and bridges, and trade with Jia Zhili. At the same time, the Secretary of Economics and Strategy of Henan Province also settled fields in Tang, Deng, Shen, Yu, Song, Ru, Cai, Hao and Ying to solve the army's salary. According to this arrangement, the Mongols were heavily guarded from the east, through Xiangyang, to the border area between Tang and Deng and the battlefield in Sichuan and Sichuan in the west, which changed the previous strategy of looting and harassing Shandong and changed to the policy of heavily guarding, plowing and guarding the valley, striving for profits and restoring the economy at the same time

In the previous war against Song Dynasty, the Bashu battlefield made great progress, but the Huaihe River and Jingxiang were divided and the progress was slow. Mongo changed the previous strategy of three fronts going hand in hand and still adopted the strategy of destroying gold. In the second year of Xianzong (the 12th year of Song Chun 1252), Mongo ordered Kublai Khan and go to dali to outflank the Southern Song Dynasty on a larger scale.

Like Xu Liewu's Western Expedition, two out of every ten people were drawn from the armies of the kings of the East and the West, and a Wang Zong was sent to follow Kublai Khan's expedition, with the son of general Ubisoft as a military commander. At the same time, there are Han troops led by Dong Wenyong, Dong Wenzhong and Zheng Ding. Before marching, as usual, people were sent to Dali for help. In the third year (1253, the first year of Baoyu), Kublai Khan arrived in Lintao, and Zhao Agpan, the leader of Tubo and a fellow official of Lintao, ordered his son to lead the army. Thanks to the support and assistance of his brother Zhao Agpan, the army successfully passed through the Tubo and Qiang areas such as Diedang.

After studying in Tela (also known as Tara, now Dalagou, Diebu County, Gansu Province, bordering ruoergai county, Sichuan Province), the soldiers were divided into three roads. "General Wulianghatai led the soldiers from the western regions, and the banquet was the way (now Aba grassland in Sichuan); When the kings copied each other, they were only fierce and handsome, from Bai Man; The emperor (Kublai Khan) learned from the Middle Road. "

Wulianghatai passed through Seda, Ganzi, Xinlong, Litang, Daocheng and Derong in Sichuan, and made a smooth progress. In autumn, he entered Yunnan from Dandangling (now central Yunnan).

Appreciation of Ancient Landscape Paintings Kublai Khan went south along the west bank of Dadu River through Aba Grassland, and conquered pastoral tribes all the way. Yutong (now Kangding East Road), Changhe (now west of Dadu River in Luding County) and Ningyuan (now Shimian County and Jiulong County) surrendered one after another. Then cross the Dadu River and enter the realm of Song, Li and Ya. Yang Tusi, one of the five chieftains of Qing Qiang, took the lead in meeting Gao Baosi and led his army to surrender to the tribes on the east coast. In September, Kublai Khan attacked Lizhou. After flying over the ridge (now northwest of Hanyuan County), it arrived at Mantuo City (that is, Songpan Tuozhai, now between Feiyue Ridge and Shicheng in northwest of Hanyuan County). The overseers left the trench of the development city and quickly went south to meet the west road. 10, the middle route army crossed the Dadu River at Fulin Ferry. Take the Qingxi ancient road, cross the Anning Valley, "travel more than 2,000 miles in the Valley", arrive at Jinsha River in November, and cross the river with a leather raft. Cross the river from the side of Beishengfu (now Yongsheng, Yunnan) and then go south from Shiguan, Lijiang. The middle road passes through the Dadu River Valley, with winding mountain roads and sometimes "hiking". Kublai Khan went through difficulties and obstacles and had to be carried by Zheng Ding, a general of the Han Dynasty.

Take the ancient pass on the East Road from northwest Sichuan to Neijun, and from Tela to Songpan (now Songpan, Sichuan) and Mao Wen (now Mao Wen, Sichuan). Out of the Minjiang old road, through Chengdu, attack Dali Baimanjie, adjacent to southern Sichuan. When Yu Jie was dead, the new Shu Shuai was incompetent, and Sichuan's defense failed, the East Route Army successfully passed the defense line, went down to Lebanon and Ya 'an, and crossed the Dadu River.

Dali refused to accept the appeal and stepped up his defense. With the support and help of Moho people (more than 400 miles north of Dali), Wulianghatai entered Chahanzhang (now Lijiang, Yunnan), captured the tribes that were not reported, and disrupted the defense deployment of Dali. 1February 13, the army assembled and surrounded Dali city. 15, the city broke. Duan Xingzhi, the Lord of Dali Kingdom, fled Kunming, Yunnan, and Gao Xiang, the Prime Minister of Dali Kingdom, fled to Tongyaluo (Yao 'an, Yunnan) and was hunted down.

In the spring of four years (1254), Kublai Khan dispatched troops, leaving Wulianghatai to defend Dali and continue to conquer tribes that had not yet joined. In autumn, a good explanation is under the boundless stage. In five years (1255), progress was made in songkhla Pavilion (now western Guizhou) and Luoluo Temple (now Liangshan, Sichuan). All parts of Dali were conquered. In six years (1256), Duan Xingzhi presented a map of Dali.

Kublai Khan invaded Dali, outflanked the Mongolian army and attacked the Song Dynasty from the south of the Yangtze River, which opened up a new battlefield. Since then, Wulianghatai stationed in Yunnan has moved to Sichuan, Guizhou and Guangxi respectively.

In the sixth year of Xianzong (1256), Mongolian kings met in Du Ge (the land was destroyed on the first day of the month) to discuss the large-scale logging in the Song Dynasty. The war aimed at destroying the Song Dynasty was in full swing. The Mongolian army is still divided into two roads, heading south. The left-wing army, under the command of Taghachar, includes Ye Songge, Chahula, Hu Linchi, Xu, Tieligan kings and generals. It has not only sons, but also busy elder brother Chaer and Chahan, so it is called 300,000 troops. The right wing was led by Mongo himself, including He Ahei (or He Dan), Toutahei, the breakthrough of the Chagatai system, He Dan's neighbors Abby and Xue Chan, the last eldest brother of the system, Meng Ge, A Zi, Su Dai and Nuchi. In addition, there are various armies and the Han army. 1256 autumn, Taghachar led the left-wing army south. They crossed Dongping to the Han River, attacking Xiang and Fan. Because of lax military discipline, but keen on looting, failed to capture a city and a place, was condemned by Khan.

1257, Taghachar attacked Fancheng. "It rained for several months, so the soldiers were transferred.".

1258, Mongo started his career. In April, stationed in Liupanshan, mobilized an army of 40 thousand, claiming to be 100 thousand, and entered Shu in three ways. Meng Ge led the main force to enter the big three levels from Longzhou; In the last years of kings, my brother was shut down by foreigners' Micang; Wan was taken to Mianzhou.

Schilling left-wing Taghachar pretended to attack the Huaihe River, Li Jue attacked Song Donghai and contained Song Jun in the Jianghuai battlefield; The Mongolian general who stayed in Chengdu, a new neighbor, rushed to Mahu to attack Chongqing and contain Song Jun in Sichuan. Mogo and Balicha took the lead and followed the army to remove obstacles. Later, because Taghachar failed to command the left-wing division, he was repeatedly blocked and was relieved of the important task of commander-in-chief. Instead, Kublai Khan was exiled. As the host commander, Zhang Rou was still ordered to levy Hubei from Kublai Khan and go to Hangzhou. I ordered Wulianghatai to go north from Yunnan and meet the East Route Army in Changsha in the first month of the following year.

In July, Meng Ge stayed in Jingzhao with Ming An, and General Hunduhai stayed in Liupan Mountain Trench. He led his own troops from Longzhou, passed through the junior pass to Hanzhong, and took Jinniu Road into Sichuan to Lizhou. Take Kuzhuguan in the west of Jianmenguan (now Zhujiazhai), stretch to Yining Mountain City (now southeast of Jiange County and northwest of Cangxi County), gain a lot (40 miles south of Jiaoxi County), Yunshan (also known as Yunshan Pass, Yanshan Pass and 30 miles southeast of Peng 'an County), Qingju (now 30 miles south of Nanchong) and Daliang (south bank of Qujiang River Basin). At the end of the year, attack Chongqing. Since the Mongolian army entered Shu, dozens of mountain cities in the territory have fallen, fallen or been besieged. Only Fishing Town, 70km north of Chongqing, can really shoulder the responsibility of shielding Chongqing and supporting the Anti-Japanese War.

"The fishing town is located at the intersection of Jialing River, Qujiang River and Fujiang River. It is a fan-shaped area with three rivers in front and Huaying Mountain in the back. It can not only prevent the south Mongolian army from taking advantage of the situation to cover Chongqing, but also connect Qujiang to form a defense line and block the road to Kaida and Kuixia. " At the same time, "there are cliffs all around" and "it is dangerous in the mountains". The commander-in-chief of fishing town is the commander-in-chief of Song Xingyuan. He adopted the policy of "protecting the people and practicing martial arts". The soldiers were well fed and strong, and had the conditions for the military and civilians in the city to stick to it for a long time and fight independently.

Meng Ge is determined to capture the fishing city. He ordered his men to divide their forces to cut off the contact between the fishing city and the outside world, and prepared various siege weapons to surround and attack the fishing city. In the Southern Song Dynasty, troops were sent to attack Chengdu to solve the siege of the fishing city, but it failed. The Mongols were besieged, with heavy losses and low morale. Lv Wende, the Song general who came to reinforce, was beaten back, but the siege lasted for more than five months, with no progress and the surrender was rejected. In July, after a long period of drought and heat, Mungo died of a serious epidemic in the army. With the sergeant, except the king and the new neighboring army, all the others retreated to the north with Meng Gezi Asu.

After Kublai Khan was ordered to go south, he set out from Kaiping in 1259 1 1 month, and went to Xingzhou in February, Zhou Pu in May and Xiangzhou in June. Along the way, he called on Chen Han, Confucian scholars and hermits, asking about operational strategies and gains and losses. In July, it was learned from the prisoners of the Southern Song Dynasty that Meng Ge died in the Sichuan Army. I don't believe it. Keep going south. In September, we crossed the Huaihe River, breached Dashengguan (now south of luoshan county, Henan Province), entered Huaixi, arrived in Huangpi (now north of Huangpi County, Hubei Province), and decided to cross the river from Yangluobao (now Yangluo Town, Xinzhou, Hubei Province) and station troops in Jiangbei. In September, the news of Mungo's death came from his late brother who went on an expedition to Shu, demanding that Kublai Khan reigned in the north. However, Kublai Khan did not want to return in vain, so he organized various armies to successfully cross the river and attack Ezhou (now Wuchang, Hubei). In the Southern Song Dynasty, Kublai Khan mobilized troops to help Hubei, while continuing to attack the city, while sending troops south to Hunan to meet Wulianghatai who entered Hunan from Guangxi. After Meng Ge's death, the military pressure on Sichuan in the Southern Song Dynasty was reduced, and Lv Wende returned to Hubei to help, so the pressure on the Eastern Route Army suddenly increased. However, Jia Sidao, the powerful minister of the Southern Song Dynasty, the right prime minister and the envoy of Jinghu to Fu Xuan, was afraid of the enemy and did not dare to fight. He sent a secret envoy to the Mongolian army to make peace. 1 1 month, Kublai Khan's wife Cha Yu sent an envoy to the front of the army, asking him to come back quickly. After Kublai Khan made peace with Jia Sidao, he withdrew to the north. The Mongolian-Song War was suspended and the border situation eased.
