Zhao Guangyi, Taizong of the Song Dynasty, was registered in 986 A.D., and it has been six years since he pinched his fingers.

The six years of emperor's journey made Zhao Guangyi feel physically and mentally tired, and his body seemed to be able to recover from a few good sleeps; But the weariness of the soul cannot be cured.

It is difficult to cure and cure, Zhao Guangyi strives to make up for his shortcomings.

So, soon after ascending the throne of the emperor, he launched an attack on the small court of the Northern Han Dynasty in a corner of the country; The small court of the Northern Han Dynasty was overthrown by the powerful Song army, and Liu Jiyuan, the lord of the Northern Han Dynasty, surrendered.

The surrender of Liu Jiyuan, the lord of the Northern Han Dynasty, did not attract the attention of Song Taizong, in his mind; The "hard bone" of the Northern Han court, which was difficult to conquer during the reign of his brother Zhao Kuangyin, was simply vulnerable in his hands.

In this sense, Zhao Guangyi feels many times better than his brother and wiser.

Zhao Guangyi thinks that another realization of his wisdom is to get the Northern Han general Yang Ye Yang invincible, and Yang Ye to submit to the Song Dynasty; It made Zhao Guangyi a little flustered, and it was easy to send troops to seize the sixteen states of Yanyun.

However, the development of events was not subject to Zhao Guangyi's wishes, and the Song army was defeated when attacking Youzhou, the land occupied by the Liao State; Zhao Guangyi was poisoned by an arrow and snatched a donkey cart to get Bianliang back, which became an indelible shame in his heart.

In May 979 (the fourth year of the Taiping Rejuvenation of the Kingdom), the Northern Song Dynasty destroyed the Northern Han Dynasty, and the Song and Liao confronted each other directly.

The line of contact between the two sides roughly starts from Nigukou (Dagukou, Tianjin) in the east, Xin'anjun (east of Baxian County, Hebei), Bazhou, and Rongcheng (southeast of Dingxing, Hebei) in the Juma River Basin in the west, and then turns northwest to Feihu (north of Laiyuan, Hebei) and south of Lingqiu (Lingqiu, Shanxi), and reaches Yanmen (north of Daixian, Shanxi) in Daizhou.

To the north of this line is the Youyun region controlled by Liao. At that time, it was customary to call the 7 prefectures of Tan, Shun, Ji, You, Zhuo, Mo and Ying in the southeast of the northern foot of Taihang Mountain in the 16 states of Youyun as "mountain front", and the 9 prefectures of Confucianism, Concubine, Wu, Xin, Yun, Shuo, Huan, Ying and Dai in the northwest of Taihang Mountain as "mountain queen".

Liao attaches great importance to this area, especially Youzhou, in addition to sending the prime minister, Nanjing to stay in Han Derang and the general Yelu Xiezhen to lead troops to defend Youzhou, but also on the basis of the Sui and Tang Dynasties Jicheng to carry out a large-scale expansion of Youzhou, so that Youzhou City has become a 36 miles in radius, the city is 3 zhang high, 1.5 zhang wide, and the population of 300,000 is the capital and military and political town.

When the Song army eliminated the Northern Han, it amassed hundreds of thousands of troops in Taiyuan; Zhao Guangyi tried to take advantage of the aftermath of the victory to seize the Youyun region in one fell swoop.

Liu Jiyuan of the Northern Han Dynasty had surrendered, and Song Taizong returned to Zhenzhou and transferred his troops to the north. However, the three armies have not yet been rewarded for breaking Taiyuan, and many of the generals are reluctant to do it, but no one dares to say it. Only the Marquis of Yu in front of the palace, Cui Han, is in favor of taking advantage of the northern expedition, "The one who should be the one is also powerful; Those who cannot be lost are also timely. Taking advantage of this momentum, it is very easy to take."

Zhao Guangyi was very happy when he heard this, and immediately ordered the privy envoy Cao Bin to transfer troops from all over the country.

At that time, most of the generals of the Song army were much calmer than Zhao Guangyi, and they thought that the army was gathered and the grain storage was too late.

Zhao Guangyi came to block the troops, and issued an edict to send the military reserves of Jingdong and Hebei Prefectures, and transferred them to the north of Zhenzhou to prepare for supplies within a time limit.

At that time, did the Sixth Army arrive at the designated place on time to assemble; Zhao Guangyi was furious and wanted to be dealt with according to military law, but was discouraged by his subordinates.

At that time, Liao's defense of Yandi had already been deployed. In March, when the Song army attacked the Northern Han Dynasty and Han Yu, Yelu Shanbu, and Yelu Sha rescued the Northern Han Dynasty, Liao had already sent Yelu Xidi, the king of the Northern Courtyard, the general, Xiao Qigu, and the king of the second room, Sahe, to lead troops to defend Yandi, indicating that they had already considered the possible attack of the Song army.

The Han soldiers often stationed in Youzhou by Liao include Shenwu, Konghe, Yulin, Xiaowu and other armies, with a total of more than 18,000 horsemen; There are also 1,950 relics on duty in the Khitan, Jiunu, Xi, and North and South leather rooms. If the Khitan invaded the south on a large scale, they would generally mobilize troops from Tokyo (Liaoyang Prefecture) and Zhongjing (Dading Mansion), with a strength of more than 200,000 troops.

On May 20, the Song army marched eastward from Taiyuan, crossed the Taihang Mountain, and arrived at Zhenzhou (Zhengding, Hebei) on the 29th, and entered the Hebei Plain.

On the seventh day of June, Zhao Guangyi sent weapons, equipment, and grain from Jingdong and Hebei Prefectures to the front.

On June 13, Zhao Guangyi, Taizong of the Song Dynasty, set out from Zhenzhou and went to Jintaitun on the 19th, recruiting 100 people as guides.

On the 20th, to the west of the East Yi Prefecture (when the Song and Liao were placed in a Yi Prefecture, the west belonged to the Song Dynasty, and the east belonged to Liao), and crossed the Juma River into the Liao territory.

Liu Yu, the assassin of Liaoyi Prefecture, and Liu Houde, the judge of Zhuozhou, successively surrendered to the Song army in Yizhou and Zhuozhou - Liu Yu and Liu Houde were Han Chinese, and they subordinated to the Khitans and became Liao officials; When the army of the Central Plains court arrived, they were willing to go home and return to the team; It is also reasonable to give up the state capital.

The Song army advanced quickly. On June 23, Zhao Guangyi's army went to the south of Youzhou City to garrison Baoguang Temple.

At that time, the defender of Liao Nanjing (Song called Youzhou, Liao was where Nanjing's Xijin Mansion was located) was the commander of the right to know Nanjing, and Han Derang, the left-behind guard of Nanjing, and the right to know Nanjing, Ma Bujun, both commanded Yelu Xuegu.

In addition, Yelu Xidi, the king of the Liaobei Academy, and Xiao Qigu, the commander of the army, were stationed in the north of the city.

The vanguard of the Song army, the commander of the east and west classes, Fu Qian and Kong Shouzheng patrolled the north of the city, met the Liao army in Shahe, and immediately engaged it with the first soldiers and horses, and the rear army arrived soon after, and then all the armies gathered, defeated the army of Xi Di, Qiu Gu and the king of the second room, and captured more than 500 people.

The king of the Southern Liaoning Academy, Yelu, slanted to the victory of the troops (northwest of Tianshou Mountain, Changping, Hebei), and saw that the Song army was in full swing and did not dare to directly clash with it; Taking advantage of the new defeat of Yelu Xidi, he used the green banner to pretend to contain the rout of the army to lure the enemy.

When Zhao Guangyi got the report of the horse scout, he had the heart to despise the enemy; The army continued to attack, and the soldiers of the Song army pursued the victory and beheaded more than 1,000 ranks.

The slanted Zhen seized the opportunity to suddenly attack the rear of the Song army, and the Song army was defeated and retreated; Confronted the Diagonal Army in the north of the Qingsha River (20 miles north of Beijing).

The defenders in the city of Nanjing, Liao, received this solidarity, and their will to hold on was even firmer.

On June 25, the Song army saw that Yelu's troops were insufficient and they were only defending the danger; can only support the enemy of Youzhou, so only a force is left to confront it, and the city of Youzhou is besieged with a large army.

Dingguo Jiedu envoy Song Wei and Shangshi envoy Hou Zhaoyuan, led more than 10,000 troops to attack the southeast of the city; Heyang Jiedu made Cui Yanjin and the internal worship official Jiang Shoujun, and led more than 10,000 troops to attack the northwest; Zhangxin Jiedu made Liu Yu lead the army to attack the northeast; Dingwu Jiedu made Meng Xuanzhe attack the southwest, and used Pan Mei to know the affairs of Youzhou.

Yelu's oblique division led the Bohai Shuai Dalanhan to the Song Dynasty, and Zhao Guangyi took it as the commander of the Bohai capital.

Since then, the Song army outside the city has surrendered to the Liao army defending the city in many ways, so that the people in the city have two hearts, and then there is its Tielin Du to command Li Zalu Cun and others to surrender.

Originally outside the city, Liao Yuzhan Langjun Yelu learned to increase the ancient defense of the city, and conspired with Han Derang and others to defend the palace, stabilize the side, and the defenders settled down to defend the city.

On June 26, Zhao Guangyi marched from Baoguang Temple in the south of the city to the north of the city, and personally supervised the generals to march and attack the Liao army in Qingshahe.

On the day of the battle, many enemies were killed, more than 300 horses were obtained, but the Liao army was a little weak, but still held on to it by virtue of danger.

On the 30th, Zhao Guangyi supervised the siege of the city, and the Song army of 300 people landed in the city by night and was captured by the battle of Yelu Xueguli; Later, he discovered and blocked the tunnel dug by the Song army, and repaired the garrison to wait for reinforcements.

At that time, Liao Nanjing was besieged, and it shook far and near, and Liu Tingsu, the defender of Liaoshun Prefecture, and Liu Shouen, the guard general of Jizhou, led their troops to surrender to the Song Dynasty one after another.

On June 30, Yelu Xian of Liaojingzong heard that Nanjing was besieged, and although the armies of Yelu Xidi, Xiao Qiugu, and Yelu Xianzhen were not defeated, they could not come to the aid and could only support, so they hurriedly sent Yelu Sha, the prime minister of Nanfu, to lead the troops to rescue.

The Song army besieged the fortified city of Youzhou, and the soldiers were sluggish and demoralized.

On the sixth day of the seventh month, Yelusha's army arrived in Youzhou, Zhao Guangyi supervised the Zhulu army to attack, and the two armies fought in the Gaoliang River.

However, the Song army at that time continued to storm Youzhou City for nearly 20 days, and the soldiers were already exhausted, so although they were victorious, they only pursued more than ten miles from noon to evening.

To Zhao Guangyi's surprise, Yelu Hugo led the army to come by surprise; Everyone rushed straight with torches in hand.

The Song army didn't know how much it was, and they were already frightened before they could engage in battle, so they didn't dare to engage in battle, and wanted to use the Gaoliang River as a defense plan.

Yelu Hugo first contained the defeated army of Yerusha, made it go back to fight again, and held on to the Song army, and then commanded the elite cavalry with Yelu obliquely, advanced from the left and right flanks of Yerusha, and attacked the Song army at night, implementing the situation of encirclement and pincer attack on both wings.

The battle was extremely fierce, and Jereux took the lead, and was defeated by the three creations.

In the city, Yeluxue Guwen heard that the reinforcements had arrived, and they also opened the door and lined up, drums sounded on all sides, and the residents of the city shouted, and the sound shook the heavens and the earth......
