On the seventh day of October, the Song naval army in Xijing City suddenly launched an artillery bombardment on the Jin army camps on both sides of the Datong River from the water gate. Under the cover of heavy shelling, a group of people rushed out from the east gate, with hoes and pickaxes in their hands and firewood and grass on their shoulders, and went straight to the deep trench dug by the Jin army to lock the city. At a glance, the Jin army knew what was going on in the road, and they had the intention to stop it, but they couldn't raise their heads at all due to the fierce artillery fire, and they couldn't rush through this line of fire, so they could only watch the trench that they had spent a long time digging being filled in little by little.

When the artillery fire stopped, the wall of the Jin army outside the city had been blown down several gaps, the ditch was filled with several passages, the main gate of the Xijing East City and the four auxiliary gates were opened, and more than 10,000 cavalry of the Song army rushed out of the city, and after crossing the trench, they discharged a front arrow formation and launched an attack on the Jin army camp. The Jin army guards were shocked and hurriedly led their troops to meet the battle, but before they could discharge the formation, the Song army's vanguard had already been killed, and the Jin army that had just gathered under the continuous shooting of the guns fell one after another, where could the formation be listed in the panic.

The dragoons of the Song army broke through the large formation of the Jin army with lightning speed, and the prancing horse entered from the collapsed wall, and after a rampage, the camp was tossed in a terrible way, and the dead bodies in the stockade were rampant, and the fire was soaring, as if it was a hell on earth. The Song army, which had collapsed the camp, quickly divided into left and right under the command of the trumpet, and the two armies came back from outside the camp.

Besieging the east gate was a troop of 10,000 men of the Jin army, and the commander of the army who led the army had fought against the Song army, which was embroidered with galloping leopards on its flag, and knew that they were the best at dividing and encircling them, and after turning back, they would surround the whole army and tear them into pieces like leopards. You can look at the ruined and unsightly battalion, and the soldiers scurrying around in a panic. He knew that he would not be able to stop the Song army without the support of the array and the wall, so he had to run fast for now.

But it's not so easy to run. Running east was the hinterland of Goryeo, and even if the Song army got out of the way and let him go that way, he wouldn't go. It was a dead end, and if they were not killed by the Goryeo soldiers and civilians who hated them to the bone, they would have to starve to death and be trapped to death; On the other side of the south, there is the sea, and they are not sailors, let alone boats, so they can only jump into the sea to feed the fish; Running west, more than a dozen of the largest warships of the Song fleet were floating on the river, and they would never look at them and let them pass; There is only one way, and that is to cross the upper reaches of the Datong River to the north and return to the north bank. Rendezvous with the Great Army.

After thinking about it, the commander of the Jin army sounded the horn and summoned the scattered soldiers to flee north around the Xijing city wall, intending to cross the river from the two pontoon bridges there. But the wise man may have a mistake, he forgot that the Datong River is from the Xijing City through the city, and the warships of the Song army can enter from this side, of course, they can also go out from that side, and he is a little dumbfounded when he leads four or five thousand defeated troops to break through the resistance of the Song army and come to the riverside.

At this time, the pontoon bridge on the river had been burned by the Song Water Army's boat, which cut off the retreat of the Jin army on the other side of the river. But when they drove their horses into the water and crossed halfway, Song Shuijun took advantage of the danger. Three medium-sized warships sailed out of the water gate, followed by dozens of them. The warships didn't fire their guns, but just rushed back and forth in the river.

Though the boat was made of wood, it was harder than meat and bone. The people and the war horses couldn't even withstand their rubbing, and for a time the Jin army fell into the water one after another, and the men and horses rose and fell on the river. And Song Jun pretended to be a good guy at this time. Came over in a small boat, and the shot of resistance ended. Those who surrendered were hooked onto the boat and thrown on the boat like dead pigs. It's just that there are too many people who fell into the water, the Song army is not well prepared, and the water is also cooler, and many Jin soldiers can't wait for their 'rescue' and sink to the bottom!

He relied on the perfect coordination of men and horses, drilled left and right, dodged the collision of the battleship, the pursuit of the boat, and crossed the river to see the anxious faces of the brothers who met them on the other side, they were jumping and screaming, and kept firing arrows at the enemy ships in the river, trying to drive them away, but unfortunately their bows were too soft, they couldn't shoot at all, and they fell into the water battle and drifted away with the river.

"Don't shoot arrows!" The commander of the Jin army shouted at the other side, he was not distressed about the hard-won arrows and advised them to save, but he was worried that he would be injured by the stray arrows, and now he had to hide from the Song army warships in the river, and also look at the arrows falling from the sky, which was very hard. Not to mention that he has to do things wholeheartedly, he was so distracted, he didn't see it, he was hit by the oar on the horse's buttocks, the horse sank back in pain, he slid into the water, just broke out of the water, another oar fell, slapped him back into the water, followed by two, three, four... Until the battleship sailed by, at this time the human head had been slapped into a rotten watermelon!

At the end of the battle in the morning, the Jin army in Dongcheng was defeated, and the blockade was lifted, opening up the passage between Xijing and Kaijing. The Jin army's 10,000 people only had less than 500 people who escaped the Song army's land and water pursuit and fled back to the camp on the west bank.

………

As soon as the battle began, he lost a team of 10,000 people, broke a general, and what was even more infuriating was that his plan to lock the city failed, and the two armies became a situation of confrontation across the river, which made Wushu very angry. But angry is angry, Wushu has not been confused, after all, it is not the first time to lose, it has been worse than this several times, and it has already exercised a strong endurance.

Wushu analyzed, the reason why his plan failed, or the defeat of the naval army, the Song army had warships to help, and the artillery fire was fierce, giving strong support to the infantry army, so to defeat them, we must first find a way to annihilate the Song army's naval division.

Following this line of thought, Wushu found that he still had a chance, the small and medium-sized warships of the Song Navy could be stationed in the city through the water gate of Xijing City, and with the protection of the city, he had no way to take them for a while, but those large warships were wide and fat and could not pass through the water gate, so they could only be moored on the river. As long as one is sunk, the entire river can be blocked, and the battleships on the Datong River will be trapped in the city, and when it freezes, it will become a pile of waste, and it will not be able to move if it wants to.

The easiest and most economical way to do this is to send water spirits to dig a hole in the bottom of the ship, so that the river water will pour into the cabin and sink the ship. So the Wushu selected a group of soldiers from the army who were proficient in water, promised a heavy reward, and sent them to dig the boat. But this plan died before it could be implemented, because the cold cold, whom he had always regarded as a friend, became his enemy.

If the water ghosts want to scuttle the boat, they must first swim across the river two hundred paces wide, and none of the recruited water ghosts can hold on to the cold water for so long, even if they can escape the sentries on the battleship and send them to the side of the battleship in small boats, they have to chisel through the water with a two-foot-thick plank, and the hole that is too big for the people on the boat to plug in time is not something that can be completed in a while, and the people who are soaked in the icy water have already had cramps in their frozen hands and feet, and they can't hold the axe and chisel.

If one plan doesn't work, one more plan will be regenerated, and if melee combat doesn't work, carry out long-range attacks. The Jin army had no artillery, the commonly used bows and arrows could not be shot, and even if they hit the ship, the power was insufficient, and the only option was the killer stone throwing machine. The stone throwers equipped by the Jin army were originally mostly captured by the Song army, and they were almost worn out in the war over the years, but they learned to imitate them in use.

Among them, the most powerful heavy artillery truck has seven guns, which require 150 to 250 men to pull the artillery rope and fire 70 to 100 pounds of stone bullets, with a range of up to 50 paces. Because the Song warship is far away, in the case of reducing the stone bullets fired, the range is still guaranteed, even if the use of 30 catties of stone bullets on the ship can cause great damage, and the Song warship is moored on the river, the volume is large and it is difficult to dodge, it is almost a fixed target, and the probability of hitting is not small.

He also knew that the range of his stone cannon was not as good as that of the Song army's artillery, so it was also within its range, and if it was easy to be discovered by the Song army in the daytime, it would be destroyed. So I can only work secretly in the dark. This kind of heavy cannon is very cumbersome, the gun mount must be fixed when used, most of the gun mount is fixed on the ground or the base is buried in the ground to cast, the mobility is poor, the installation is time-consuming and laborious, and it is mostly used to attack and defend the city on weekdays. Not to mention the difficulties, Wushu personally supervised the formation, and more than 40 stone throwers were erected under the noses of the Song army overnight.

In the early morning, the river was shrouded in mist, and the lookout posts of the Song army did not notice the changes on the other side, and the Jin army probably did not attack rashly in order to ensure that the first blow would be successful. When the sun rose, the Jin army suddenly withdrew the gate flag in front of the formation and began to attack. Because the catapult adopts the method of visual probability aiming, and it also needs to adjust the size of the stone projectile and the number of people required to pull the cable to ensure accuracy through the impact point of the test shot, so the first shot is a single cannon fire.

The Song army didn't realize that Jin Jun had played a new trick at first, and only realized that he had been calculated when he saw a stone projectile sweep over the side of the ship and fall into the water and splash into the water. They also reacted quickly, immediately sounded the alarm, and the battleships anchored on the river immediately pulled anchor and set sail, evacuated the formation, reduced the chance of being hit, and at the same time looked for the location of the enemy's trebuchet, ready to launch a counterattack.

Wushu found that the Song warships began to move to avoid the attack, and he didn't care about the test firing one after another, and ordered to fire at the largest flagship on the river. Although the trebuchet launch is not as earth-shattering as the artillery launch, the scene is spectacular enough, more than 40 trebuchets shot the first wave of bullets together in the roar of thousands of people, and it is scary enough to watch the countless stone bullets in the air come to the face like birds throwing into the forest......
