Xiongxian County, Hebei Province has been occupied by the Liao army first, so that the Liao army obtained this dangerous city, and the main force of the Song army's 60,000 West Road army was stationed in a wilderness in the south of Xiongxian, Xiongxian is surrounded by hills, undulating mountains, and is not suitable for a decisive battle of the army, Liu Yanqing originally planned to march to the Baigou line and the Liao army to fight a decisive battle, but Yelu Dashi led 20,000 troops to defend Xiongxian and never fight.

The Song army was seriously short of siege weapons, and they faced each other for ten days, but Naxiong County was helpless.

In the big tent, a war urging officer sent by Tong Guan was arguing with Liu Yanqing, Liu Yanqing was furious and shouted: "Keep telling me to fight, why don't I want to?" Where are the siege ladders? Where is the ladder? Where is the nest car? Nothing, how can we attack the city, this is the so-called Northern Expedition war preparations, nothing is ready, a fart battle! ”

The urging officer also said angrily: "There are no siege weapons, you can build them yourself, there are big trees here, and there are carpenters in the army, why can't you build your own siege ladders, and count on Captain Tong with all your heart, this is still everything in control?" ”

Liu Yanqing smiled angrily, and pulled the warlord out of the big tent, "Open your dog's eyes and see, where is there a tree within twenty miles around?" The Liao army is strong and clear, do you think that everyone else is the same as Tong Gelding, and they came to the Northern Expedition without any preparation! ”

"Liu Dutong, please keep your mouth clean and be careful to treat your crime of disrespect!"

"I have something worse to say! When will our grain be delivered, we will run out of grain tomorrow, why will the grain and grass in Pingying Valley not move? ”

The war officer stretched his face and said: "The grain for this Northern Expedition was insufficient, a large amount of grain was still in transit, and the ships went to transport Huashigang, and there were no ships to transport grain across the Yellow River, this is the responsibility of the imperial court, what does it have to do with Taiwei Tong?" ”

"No matter how bad the food is, there are still 20,000 stones of grain and grass in Pingying Valley, which can solve our urgent needs, but you refuse to send food, you are obviously deliberately making things difficult for me, the enemy is still engaged in factional struggle, is it wrong to call him Tong Gelding?"

The warlord was furious, "Since you refuse to send troops, then I will go back and report to the captain and take my leave!" ”

The warlord rushed away with a dozen of his men in a rage.

Liu Yanqing sighed, and said to the generals in the account: "I finally understand why the old people resolutely oppose the Northern Expedition, one by one slogans shouted loudly, what a hundred years of shame, once the snow washed, what a hundred years of opportunity, the brave rushed up, the cowards were stuck, a group of civil officials were all passionate about the words, but they didn't do any business, they found that Hebei was not ready for war at the beginning of last year, and nothing has changed for more than a year?" It's really a civilian misguided country! ”

Deputy General Zhao Qin said in a low voice: "Dutong, we will run out of food tomorrow, we will have to go south to Pingying Valley for at least one day, instead of waiting for the food to run out of troops, it is better to withdraw the army overnight!" ”

Liu Yanqing was helpless, so he had to nod and say, "Pass my order and withdraw the troops overnight!" ”

．．．．．．．

As night fell, the sun had already set, and the last rays of sunset had begun to fade, and the sky was glowing with a pale blue, and a foggy dark black began to envelop the basin.

The Liao army's chief general, Yelu Dashi, stood on the lookout tower in Xiongxian County, Yelu Dashi was about thirty-five or sixteen years old, with a square face and a pair of eyes that were usually full of elegance and indifference, but at this time he revealed the coldness and perseverance of a soldier.

Although he is a Khitan, he is very knowledgeable, proficient in Chinese, and good at riding and archery, and he passed the Jinshi examination seven years ago, becoming the only Jinshi among the Khitans.

Historically, after the Liao State was destroyed by the Jin State, Yelu Dashi led tens of thousands of remnants of the Liao State into Central Asia, defeated the 400,000 allied forces of the Seljuk Empire in one fell swoop, established the Western Liao Dynasty, and became the founding emperor of the Western Liao.

Yelu Dashi is not only able to be able to stabilize the country, but also to stabilize the country, in the Liao State at the time of crisis, he resolutely served as the commander of the Liao army, and together with the deputy marshal Xiao Gan, he led 40,000 mourning soldiers to meet the 250,000 Northern Expedition Song army.

Yelu Dashi looked at the rear camp of the Song army a few miles away, the moonlight was clear tonight, and he could clearly see the Song army slowly retreating, he could see the big tents disappearing, and he could also see the Song soldiers who were retreating south in dense formations.

"General, is the retreat of the Song army luring us out of the city?" The deputy general next to him, Xiao Lira, asked in a low voice.

"I think they should be running out of food, Tong Guan is a woman's heart, and he actually brought the conflict with Gao Yu to the battlefield."

Yelu Dashi sneered, and said: "Tong Guan sent 100,000 troops in Western Xia, Zhao Ji didn't learn a lesson, and continued to send him as the commander of the Northern Expedition, God bless me Da Liao!" ”

"Since we are running out of food and retreating south, should we go out of the city to pursue?"

"Don't worry, wait patiently and see what news Yelushu Xue can bring us?"

．．．．．．．．

Pingying Valley is the only way for the Song army to go north to Xiongxian County, this is a valley about 20 miles long, the widest part has two miles, the narrowest point is only dozens of zhang, both sides are towering cliffs, because its strategic location is extremely important, Tong Guan ordered the general Wen Jing to lead 5,000 troops to build a pass here, and gathered 20,000 stone grain here, become the main logistics supply base in the north.

At night, a Liao army of 2,000 people has quietly arrived in Pingying Valley, this Liao army is the strange soldier sent by Yelu Dashi, led by the general Yelu Shuxue.

Yelu Dashi has already discovered that the weakness of the Song army is Pingying Valley, if the sneak attack captures Pingying Valley, not only can cut off the retreat of the Song army, but also cut off the food supply of the Song army, so that the Song army will be chaotic without a fight.

Yelu Shuxue was a young warrior who was only in his twenties, bold and careful, and won the trust of Yelu Dashi, at this time, he stood on a high ground and looked at the Pingying Valley in the distance.

The entrance of Pingying Valley has been built by the Song army a Guancheng, the Guancheng is about two zhang six feet high, about two miles long, there is no moat, it is located on a gentle hill, the terrain is slightly higher, the head of the city is very well guarded, there are at least hundreds of people patrolling back and forth, and there are torches on the outer city wall, which illuminates the outside of the city several zhang as day, making it difficult for them to act secretly.

From the point of view of the army's attack, it was not easy to capture this fortress, which Yelu Dashi also took into account when he sent him south, and specially gave him a secret weapon.

Yelu Shuxue pointed to Guancheng and said to several generals: "The terrain in the west is a little gentle, we can attack from this side, I am ready to put in a thousand people, enough to attract the defenders of the city, I hope you can fully cover the operation in the east." ”

Everyone nodded and said, "When is the general going to attack?" ”

Yelu Shuxue looked up at the night, it was almost three watches, he gritted his teeth and ordered: "Attack the city immediately!" ”

.........

Several Liao army generals led a thousand crossbowmen to the west city, they had just entered a hundred steps, the city head suddenly drummed loudly, the Song soldiers went to the city one after another, two thousand Song troops shot arrows downward, and the arrows were fired in unison, blocking the Liao army from continuing to advance.

At this time, the Liao army also beat the war drums, and a thousand crossbow troops shot arrows at the city head at the same time, the arrows were like flying locusts, and the dense arrows whistled towards the city head.

But the archers at the head of the Song army were twice as large as the enemy, and the powerful arrow rain formed quickly suppressed the Liao army, making it impossible for them to advance, at this moment, several Liao soldiers in the east took advantage of the opportunity of the Song army at the head of the city to be attracted by the siege of the city from the west, and quickly ran from the foot of the mountain in the east to the root of the city wall next to the gate, which happened to be in the dark, the moonlight and fire could not shine, and it was pitch black under the city wall, and it was difficult to find people below the city.

The city wall at the mouth of Pingying Valley was made of wood and mud and was not very strong, and soon the Liao army dug a large hole under the city wall.

At this time, they brought out a swarthy iron bump, if Li Yanqing saw this item, he would definitely be surprised, this item was the earth-shattering thunder that had once displayed its power in Western Xia.

This earth-shaking thunder did not leak out of the Song Dynasty, after the seed master Dao dedicated the gunpowder formula and drawings of the earth-shaking thunder to Zhao Ji, the son of heaven, he has been put in the high pavilion by Zhao Ji and hidden in the deep palace.

Even the earth-shattering thunder used by Tong Guan in the Liangshan Army was left over from Li Yanqing's attack on the Liangshan Army, and the Song Dynasty Military Weapons Supervisor did not manufacture such a sharp weapon at all.

The Liao army's earth-shaking thunder came from the Western Xia, the Western Xia found a few earth-shaking thunders in the ordnance abandoned by Tong Guan's defeat, after two years of repeated trials and research, they have successfully copied them, and specially secretly sent ten earth-shaking thunderbolts to the Liao army for use in the battle with the Jin army.

But the first time the Liao army used the earth-shaking thunder, it was used on the Song army.

Three Liao soldiers stuffed the earth-shattering thunder into the big hole, lit the fuse, and ran along the city wall, at this time, a defender at the head of the city suddenly found them, shouted, the Song army at the head of the city released arrows together, and the three Liao soldiers were immediately shot and killed.

At this moment, an earth-shattering explosion suddenly broke out under the city, the smoke was filled, the dust was flying, and the Liao soldiers who were fighting in the west were so frightened that they lay on the ground and did not dare to move.

When the smoke cleared, Yelu Shuxue looked at the city wall again, and couldn't help but be stunned, only to see that the city wall was blown open and the city gate next to it was completely destroyed.

Yelu Shuxue immediately reacted and shouted, "Kill into the city!" ”

Two thousand Liao soldiers rushed into the Pingying Valley with shouts.......

At the time of the third watch, Yelu Dashi suddenly saw a bright fire in the distance, which was the direction of Pingying Valley, and he was suddenly overjoyed in his heart.

Yelu Dashi immediately shouted: "Pass my order, pursue the Song army on all fronts!" ”

At the end of May of the fourth year of Xuanhe, Yelu Dashi led 20,000 troops to defeat the main force of the 60,000 Song army in Xiongxian County, and at the same time, Xiao Gan also led 20,000 troops to defeat the 50,000 troops of Xin Xingzong on the East Road in Zhuo County, and the 110,000 Song troops fled with countless casualties.

Yelu Dashi led the army to kill more than 100 miles in one go, but he was worried that the Jin army would take the opportunity to go south, so he did not pursue it with all his strength, so that the Song army of the two roads avoided the fate of the annihilation of the whole army.

The news of the crushing defeat of the two Song armies at the border was transmitted back to the capital, and the government and the opposition were shaken for a while, and Zhao Ji, the son of heaven, was frightened and immediately issued an edict.
