PS: Ma Zhengsheng is the deputy commander of the artillery regiment, and the regiment commander should be Xin Feiyu, a traverser. In the previous chapter, Ma Zhengsheng was written as the head of the regiment due to the negligence of the idlers, which is hereby corrected and apologized to the book friends.

**************************************************************

Just when the Liao Army's pontoon bridge was blown up, the battle in front of the camp of the northern front of the "Southern Route Army" was basically over, and only a few hundred of the Liao troops who had 5,000 of them were able to escape back to their own camp, and the rest were killed under the guns and cannons of the northern line troops of the "Southern Route Army" and the cavalry regiment of the "Flying Dragon Army" and the cavalry battalion of the Ranger Battalion that had come out of the camp at the right time. In a car formation in the middle of the camp of the "Southern Route Army", Ma Zhengsheng, deputy commander of the artillery regiment, had already commanded his gunners and craftsmen to prepare the most powerful "hammer" that Qian Yuanshan said needed to give the Liao army a blow. I saw that in the middle of the car formation, six black and shiny steel brackets were neatly arranged in a row, and at the same angle, Xiangshang was inclined to point in the direction of the Liao army camp. At the tail of the six steel brackets, the gunners of the artillery regiment and the craftsmen of the accompanying army are installing ammunition on the rails of the brackets.

-- Thanks to the joint efforts of the Weapons Section of the Ministry of Science and Technology and other sections, the rocket artillery, which was originally regarded as a chicken rib by the brothers of the Ministry of Military Affairs, has been greatly improved. Not only has the firing range been increased (from four miles to six miles), but the charge of the rocket warhead has also been increased (its power is basically equivalent to that of a 105mm howitzer), and it basically has actual combat capability, and it is no longer an "embroidered pillow" type of equipment that is "useless" in the mouths of the brothers in the military department. The only thing that limits the number of rocket artillery equipment is the price of its rockets - the price of one rocket is equivalent to three 105mm grenades - and even an organization like the Crossing Team, which has a deep pockets and a penchant for large sums of money in military spending, is still very cautious about equipping large quantities of rocket artillery. In order not to affect the production speed of other weapons and equipment, before the Youyun War, the weapons section only rushed to produce three rocket launchers and a small number of rockets for the "Flying Dragon Army", and together with the previous three shiyans, they reluctantly formed an independent rocket artillery company, which was directly controlled by Qian Yuanshan, commander-in-chief of the "Southern Route Army," and was not included in the formation of the artillery regiment -- six launchers with 96 launch rails, but only 200 rockets were equipped, which was only enough for the whole company to fire two salvos.

Although there were only 200 rockets, a straw to serve as a zuihou to crush the camel was enough. At six o'clock (about half past ten in the morning), after about half an hour of unhurried artillery bombardment of the Liao army's camp, the so-called decisive blow to the Liao army in the Qian Yuan Pass finally began. As Qian Yuanshan gave an order, Ma Zhengsheng, deputy commander of the artillery regiment, fiercely waved down the order flag in his hand, and the rate of fire of the 78 body-barreled guns of the "Southern Route Army" suddenly accelerated, changing from conventional shooting to rapid shooting. Immediately afterwards, Qian Yuanshan personally waved the order flag, and the six rocket launchers were also divided into two groups to fire one after another. One rocket after another broke off the guide rail, flew towards the Liao army camp with its characteristic whistling sound, and stirred up puffs of smoke and dust on the launch position, and soon enveloped the entire central vehicle array.

Although the first blow of Zuihou lasted only five minutes, the various shells that were thrown into the Liao army camp reached more than 60% of the shells dropped in the previous half-hour shelling. In an instant, the entire camp of the Liao army was covered with thick smoke and flames. The Liao army, which had already been extremely nervous by the previous shelling, completely collapsed under such fierce artillery fire, and the officials at all levels could no longer control their subordinates, and tens of thousands of surviving Liao troops poured out of the Liao army camp like a flood that opened the floodgates, and fled in all directions. A group of senior generals, including Xiao Siwen, were also powerless at this time, so they could only escape from the camp with the rout.

Although they were scattered and fled, in fact most of the Liao troops fled in only one direction, that is, the mountains to the west - the north was absolutely impossible to go, and the destruction of the 5,000 cavalry had proved that running there was a dead end; Although there were only more than 100 enemy troops on the east side, the Baigou River, which was not wide but extremely deep, was an insurmountable obstacle for the Khitans, who were basically unaccustomed to water; Although the Zhou army in the south has not moved since the attack on the Liao army camp, there are nearly 80,000 Zhou troops there, and the Liao army that has broken down does not think that it can break through the Zhou army camp and escape in its current state. Therefore, the best and wisest choice is to go west into the mountains, use the cover of the mountain jungle, bypass the enemy camp in the north, and then try to escape back to Youzhou City or even to escape back to Saiwai. So, in the rumbling sound of artillery, nearly 40,000 surviving Liao troops rushed out of their own camp like a swarm, some horses desperately urged their mounts, and those without horses spread their legs, scrambling to run to the mountains not far from the west side of the camp -- of course, when the vast majority of the Liao soldiers were about to flee to the mountains, there were also a few Liao troops who were consciously brave or had completely lost their heads chose to flee to the north, south, or even east, and the result could only be to lose their lives in vain. …,

The Liao army that fled in other directions was naturally a dead end, and the Liao army that fled to the mountains on the west side soon found that their choice did not seem to be much better than that of those who seemed to them to be committing suicide. Just when tens of thousands of Liao troops ran through about a mile of road, and the Liao army that ran in the front finally got into the woods at the foot of the mountain, feeling that they could slow down a little and take a few breaths, they had already been waiting in the mountainside fortifications for most of the morning, and were itched by the guns and shouts of the northern line troops of the "Southern Route Army", and wanted to kill the Western Front troops of the "Southern Route Army" like the brothers on the northern front.

It stands to reason that the troops on the western front of the "Southern Route Army" are only half of the troops on the northern front, both in terms of total strength and the strength of the "Flying Dragon Army" under their jurisdiction, and their artillery is only the small- and medium-caliber mortars of the infantry battalions and companies, and their firepower density and power are much weaker than those of the troops on the northern front. If the fleeing Liao army attacked with all their might, it might not be impossible to break through the resistance of the troops on the Western Front and flee into the continuous mountains and dense forests further west. At that time, it will be said that there are more than 10,000 "Southern Route Army", even if all the armed Liliang of the crossing team are transferred, and even the 80,000 Zhou troops are added, it is impossible to eliminate all the Liao troops who fled into the mountains, and there will definitely be many Liao soldiers who will be able to get out of the mountains alive and return to Youzhou City or their hometown outside the Saiwai.

However, at this time, the defeated troops of the Liao army had just experienced the artillery bombardment of the northern front troops of the "Southern Route Army", and in the face of the terrible scene of heavy casualties and rivers of blood in their own camp, these escaped Liao troops had already been frightened and became frightened birds. At this time, as soon as they encountered the shelling of the troops on the Western Front, the Liao army running in front immediately panicked, turned around and ran out of the mountain, not wanting to collide with the follow-up Liao army who did not realize that the situation in front was not good, and still fled to the mountain regardless of it. As a result, these Liao troops unsurprisingly repeated the mistakes of the 5,000 Liao troops who had rushed into battle before, and tens of thousands of horses were crowded in a not wide area under the foot of the mountain, unable to move. For a time, the sound of shouting and scolding, crying, and even the clashing of weapons, the wailing of wounded soldiers, and the screams were endless.

The defeated soldiers of the Liao army blocked themselves at the foot of the mountain, and the officers and men of the "Southern Route Army" naturally would not waste such a great opportunity. Both the troops on the northern front and the troops on the western front adjusted the angle of the artillery at the fastest speed at this time, and sent shells one by one into the place where the Liao army's defeated troops were most concentrated.

Seeing that the Liao army had completely collapsed and it was impossible to break through his own defense, Qian Yuanshan immediately notified the cavalry that had just defeated the Liao army as quickly as possible, and the cavalry regiment and ranger battalion that were resting in the car formation immediately attacked, striving to annihilate all the tens of thousands of Liao troops at the foot of the mountain in the shortest possible time, so as to gain more time for the subsequent battle. At the same time, he also ordered the infantry of the "Flying Dragon Army" on the northern front, except for one battalion to continue to guard their own barracks together with the regiments of the "Security Army", and the rest of the infantry also attacked on all fronts to assist the cavalry in completing the encirclement of the defeated Liao army.

With the issuance of his order, nearly 3,000 knights of the cavalry regiment and ranger battalion immediately beat their horses out of the camp and pulled away from the camp, using a very large and at the same time relatively thin net to wrap the tens of thousands of defeated soldiers of the Liao army, preparing to draw a complete end to this battle with a large encirclement. Behind them, the same infantry of nearly 3,000 men quickly followed, on the one hand, to clear the way of the fish, and on the other hand, to form a second line of defense behind the cavalry, in case the cavalry troops were unfavorable in battle, to act as a second line of defense, to buy enough time for their own camps to prepare for battle or evacuate.

Facts have proved that Qian Yuanshan is definitely overly worried. In the face of the well-trained, well-equipped, and fierce cavalry regiments and ranger battalions, the Liao army, which had been completely defeated and completely lost its fighting spirit, could not afford to resist and counterattack at all, and its nearly 40,000 soldiers were bombarded by the cavalry of the "Southern Route Army" of less than 3,000 men, and they were soon divided into several pieces, and gave up resistance amid the unanimous and deafening shouts of "kneel and surrender without killing" from the cavalry of the "Southern Route Army," the infantry of the northern front who arrived later, and the infantry of the western front who rushed down from the mountains. Throw away the weapon in your hand and obediently tie your hands and take it.

In the afternoon of the third day of the fourth month of the lunar calendar in the ninth year of Yingli (the sixth year of Xiande), after a short battle of more than an hour, the main force of the Youyun Liao army was 80,000 horses, except for the 10,000 horses led by Xiao Jixian who were spared due to guerrilla attacks outside, the remaining 70,000 Liao troops were almost completely annihilated. Among them, more than 30,000 were killed or seriously wounded -- with the medical standards of this era, there was basically no hope of survival for the seriously wounded -- and more than 30,000 people, including Xiao Siwen and his senior subordinates, were captured, and less than 1,000 were lucky enough to pass through the gap between the northern and western fronts of the "Southern Route Army" and were able to escape the fate of being killed or captured, and fled to Youzhou City in a hurry.
