Chapter 275: Fire Attack on Huanglong The Jurchen soldiers who retreated shivered and warmed themselves by the fire. Zong Han sighed after looking at it. Originally, killing a few hundred enemies was considered good, but looking at the degree of frostbite among these soldiers, the situation was not optimistic. "Haha, the Generalissimo has become a chicken." A man passed through the scattered bullets of the Song army, jumped off his horse and laughed at Zong Han. This was none other than a perfect man who was demoted to the rank of Captain of Ten Thousands and had a deep conflict with Zong Han. Yan Zongbi. Zong Han waved his hand to stop the angry soldiers around him and said: "Wanyan Zongbi, you are not laughing at me, Zong Han, but at Jurchen." "Sorry, I made a mistake." Wanyan Zongbi asked: "How about it, Ouyang is so poisonous, isn't he? ?" As soon as he heard that Ouyang was a supervisor, he knew that this guy was going to do something bad. But I didn't expect it to be so bad. He didn't know that although Ouyang was bad, he couldn't think of such a professional solution. "Zhang Jun is not an idle person. It is almost impossible to destroy the water tanker." Wanyan Zongbi said: "I have a plan to avenge this." "What plan?" "The Song army has a car escort in front of it, and there are cavalry on the left and right to support it. It is difficult to deploy the heavy artillery. "Wanyan Zongbi said: "So they can only send a thousand people to attack the city." "What do you mean?" Wanyan Zongbi said with a smile. "Zong Han is not an idiot. , immediately understood: "You mean to let us shoot the Song troops at the top of the city from the ancient tower?" "The tower is more than 120 feet high, overlooking the city, without any obstruction. One hundred shooters stood on the tower, Song The army is like the prey we hunt, and there is nowhere to hide." "Okay," Zong Han said happily, "Then I will leave it to you." "Don't worry, I won't be as embarrassed as you." "**, Hundreds of people are gone again." After hearing the battle report, Zhang Jun got up and slapped his thigh in anger. Attacked the city twice and suffered heavy losses. Although the Jurchens' losses were not small, many people froze to death or were killed by explosions. But Zhang Jun knew that in the first confrontation, he relied entirely on his secret weapon to gain a few points, and in all calculations, he was the one who suffered the loss. Apart from killing and wounding the enemy, no strategic results were achieved at all. "This hand is very vicious." Ouyang said: "The ancient tower is one hundred and twenty feet high, and it can be clearly seen on the city wall. The Jurchens are good at shooting, and they cannot stabilize the city at all. Moreover, the attack routes of our imperial army are blocked, making it difficult to transport them all at once. "A large number of troops." Wu Jie said: "But in the end, the Jurchens are also very taboo about our army throwing water trucks." "It's useless. The water trucks can only advance to two hundred steps, and they can only hit the wall. ." Chen Gui said: "The biggest role of the waterwheel is to make the Jurchens abandon the city wall." Zhang Jun said: "Since they don't want the city wall, we don't want it either. Order the collection of explosive bags." The Song army retreated in an orderly manner in the afternoon, and the two sides temporarily stopped fighting. After a night, the Song Army started yesterday's tactics again. The convoys and cavalrymen spread out. "Report" Zong Han was drinking butter tea when a soldier came to report: "Commander, the Song army is digging tunnels under the city." "Dig tunnels?" Zong Han was shocked after thinking about it: "They are not digging tunnels." Just after he finished speaking , a huge roar sounded. Zong Han hurriedly went out, and a soldier intercepted him halfway and reported: "Commander, the Song army is blowing up the city wall." "I know" Zong Han looked ugly. He guessed what Song Jun was trying to catch. When they abandoned the city wall, the Song army dug holes under the city wall and blasted the wall. Not to mention the three-layer city wall, even ten layers were not enough for the Song army to destroy. Ants gnaw at elephants, digging you up bit by bit. "Oh, Marshal, you have to peel me off again." Wanyan Zongbi appeared. "Are you waiting for someone to blow up a big mouth?" "I mean, don't worry, Generalissimo. We have to peel it off anyway, so why not let them blow it up for a while." "What do you mean?" "Once it has an effect, they will Transport a large amount of gunpowder across the moat for continuous blasting. At this time, if you fire a few arrows, the Song army will be overwhelmed, and it will kill their escort. "" Wu Jie said: "General, a small hole has been blown out." , transport a large amount of gunpowder?" Zhang Jun did not answer and asked: "Master Ou, what do you think?" "Judging from the abandonment of the city wall, it is not easy for the Jurchen commander." Ouyang said: "But it has already been blown up. There were five or six explosives, but not even a Jurchen appeared on the wall, which was a bit weird. " Ouyang guessed with a villain's heart. "Well, I think so too." Zhang Jun said: "General Wu, pull your people back and don't let others take advantage of you again, otherwise it will greatly damage morale." Although there are few people, the feeling of defeat is not small. "Yes" Wu Jie clasped his fists and left. In the past two days, no one took advantage. Zhang Jun still has time here and is not in a hurry. Zong Han was naturally even less anxious. On the third day, when the snow stopped and the sun came out, the Song army temporarily stopped their actions. At the lunch meeting, Zhang Jun, several major generals and Ouyang were having a meeting. Zhang Jundao: "Now there are two ways. The first is to reduce the number of water trucks so that I can deploy a siege army of at least 5,000 people per unit. But in this way, it will be impossible to suppress the enemies on the city wall, which is equivalent to a hard attack. Both sides The cavalry cannot be withdrawn, otherwise in the event of a counterattack, the front army will overwhelm the rear army, which may cause a rout. The second method is to withdraw the heavy artillery, and support the city wall with a unit of 2,000 people, but without the heavy artillery, the main accumulation of troops is in the north of the city. We can easily support the city wall, that is, hand-to-hand combat. We send troops one after another, and they send troops one after another. The city wall has become a decisive point. The losses will be very heavy, and once the attack is launched, it cannot be stopped. " "The most annoying thing is that Gao Baisan. The ten-foot ancient pagoda." Ouyang asked, "Master Chen, can the water cannon hit the ancient pagoda?" "It's barely possible." Chen Gui said with a bitter smile, "As far as I know, the ancient pagoda is flooded." It is very strong, and it is made of solid bricks and flat bluestones. "No, the tower is thirteen feet high, which is already very high." After thinking about it, Zhang Jun jumped up and said, "Wu Jie, let's collect the fire oil." "Burn the ancient pagoda." Ouyang marveled at Zhang Jun's knowledge of physics. Not every modern person knows that although bricks and other building materials cannot melt at high temperatures, high temperatures can destroy their toughness and strength. Ouyang knew this principle because of the 9 Incident. I was wondering why the building collapsed? Later, I learned that the plane impact was not the cause of the building's collapse. The main reason was that the fire destroyed the toughness of the building materials, causing the building materials to be unable to support the weight, and finally they all collapsed. You must know that even modern bricks that are specially designed to prevent fire can only withstand Temperatures of over 500 degrees. But it is impossible for Zhang Jun to have participated in the 9 "My father told me that the higher the fire in the brick kiln, the better. Once it is too high, bad bricks will come out, and they will turn into powder when smashed." Zhang Jun said: "We will use the ancient bricks to make bricks." The tower was reheated. "¡So the water battle was changed to a fire battle, and the materials were all readily available, just to replace the water with fire oil. Eight hundred waterwheels suppressed the city wall, and two hundred trains attacked the ancient tower. Although most of the fire sources of the first batch of fire bombs were extinguished in flight, one or two people eventually exploded, and the fire at the bottom of the ancient tower inevitably burned. When Zong Han heard the report, he couldn't understand the intentions of the Song army at first. Then, after being reminded by the craftsmen, he hurriedly ordered: "Put out the fire." Ancient records of fierce fire oil were also called Lishui and Shiqi. The period when war played the greatest role in ancient China was the Five Dynasties and the Song, Jin, Liao and Yuan dynasties. It was also during this period that oil was called fierce fire oil. The Song Dynasty was the most mature in using fierce fire oil. The Song Dynasty established an arms supervisor in Bianliang, the capital, which was an institution specialized in manufacturing weapons. It had eleven workshops (factories), among which there was a specialized workshop for fierce kerosene. Fierce fire oil is generally used for defense, especially in city defense battles. Since there are no fire extinguishers such as carbon dioxide, water is poured on the oil, making the fire even bigger. Zong Han was horrified, and the craftsman immediately said: "Generalissimo, this is fierce fire oil. It can't be extinguished by water, so it can only be covered with sand." Zong Han hurriedly shouted: "Dig the sand." But as soon as the order was given, the Song army expanded the attack. In addition to the ten vehicles that continued to throw heavy fire oil at the location of the ancient tower, another twenty vehicles began to set fire indiscriminately around the tower. The other cars stopped attacking. After all, Menghuoyou was mainly engaged in defensive battles. Zhang Jun was limited to a certain understanding and did not bring too much. As the area expands, not only is the sand and soil strategy very effective, but Zong Han must also consider the issue of fire prevention within the army. Several soldiers were burned to death by inaccurate fire bombs. "Report" the Forbidden Army soldiers reported: "General, the heavy fire oil can only be fired again." Zhang Jun's expression did not waver at all and ordered: "Let the convoy army move, and the ten-heavy artillery unit will advance and bombard the ancient tower." Ouyang hurriedly said: "General Zhang, the Jurchen shooters are very accurate. Once the rockets are fired into the mouth of the heavy artillery and detonated in succession, our army will suffer heavy losses." "Accurate?" Zhang Jun said: "Don't worry, Mr. Ou, the mountain people have a clever plan." The sound of explosive shells booming came, and several shells exploded in the fire. The soldiers who put out the fire were killed and injured. Zong Han shouted: "Order, the shooters defend against the wall." Due to the pressure of the water tanker, everyone can only strip naked to defend, but there is no need to worry about not getting angry. They also have some of the fierce fire oil used by Zhang Jun, and the Jurchens have a lot of gunpowder arrows that were eliminated by the Tokyo Production Bureau. Moreover, Zhang Jun's waterwheel is not a continuous heavy rain after all. The city wall is more than a mile long, and if there are thousands of people on it, as long as a few can shoot rockets, they may blow up the Song army. From a high position, the shooting range of two hundred steps is relatively simple for the Jurchens. "Calibrate" the lookout hand of the ladder truck ascent??Show the signal flag and correct the impact point of each gun. After going back and forth like this, the Jurchens had already rushed to the city wall, but when they saw the Song army, they were all dumbfounded. They saw that it was not the Song army, and they could not see the position of the heavy artillery. Instead, they saw gray smoke. Looking down with sharp eyes, I vaguely saw that the convoy was burning dried feces and other smoky objects. Looking at the smoke-free areas on the left and right of the Song Army, two ladders were raised to observe the artillery fire within range, and signal flags were used to correct the artillery fire. Wanyan Zongbi said anxiously: "Generalissimo, send out the cavalry. Two hundred steps, we will be there in one breath." "Zhang Jun is a famous general, it is impossible to think of it. If he had planned it in advance and took advantage of the smoke to seize the city gate and enter, the consequences would be It¡¯s unimaginable.¡± Zong Han reluctantly ordered: ¡°Let everyone pay attention to the collapse of the ancient tower.¡± It took about a quarter of the bombing time, and the ancient tower finally couldn¡¯t withstand the double blow and declared its collapse. Zong Han watched the ancient pagoda roar and fall to the ground and sighed deeply. The next battle will be even more cruel. ¡ But the brutal battle came earlier than Zong Han imagined. That night, the Song army made a noise and fired heavy artillery. Zong Han led people to the city in an emergency while sleeping. But he didn't expect that he would still be greeted by ruthless water bombs. One of the generals asked: "Generalissimo, what should we do? To evacuate or not to evacuate?" If you evacuate, run away quickly; if you don't evacuate, everyone will take off their clothes. In the past few days, the Song army had been tormented by water bombs. Not many people had died, but a large number of them had fallen ill. Suspicious soldiers? Forward attack? Zong Han looked at the dark night and pondered for a long time with the Song army who were busy boiling water and reloading bombs in the distance and the lights were bright: "Withdraw orders to a team of 100 people and take turns to shoot arrows in the direction of 200 steps." Everyone took turns to go up and take a bath. If the Song army really attacks the city, it will inevitably cause death and screams. Zong Han went down the city wall and looked around, feeling heavy. Colds began to spread in the army, and some soldiers also developed pneumonia. Of course, it was not called pneumonia at that time, it was called lung wind. It is a combination of pneumonia and measles. The lack of medical treatment and medicine is the biggest problem facing Huanglong Mansion. The most terrible thing is that the Song Army has not launched a large-scale attack on Huanglong Mansion, but the combat effectiveness of Huanglong Mansion has dropped significantly. The next day, Song Jun's water bombing started again. Zong Han really didn't know how many ceramics Song Jun fired. He didn't know that Ouyang used all the productivity of the large factories under the name of the business association and produced them for two full months. Of course, Ouyang also had other ideas. This batch of imperial orders could greatly alleviate the embarrassing situation of overstocked inventory and no work in the factory. Objectively, it stimulated the economic recovery of the Song Dynasty. It is said that Zhao Yu cursed Ouyang and Chen Gui on the spot when he saw the required fees. On this day, the Song army and the Jurchens fought for the city wall. The Jurchens all went into battle naked, because if they didn't, they would be hit by water bombs. Although the water bombs stopped attacking after the Song Army entered the city, they had to worry about the fact that the Song Army still had the weapon of hand cannons and could not distance themselves from the Song Army. The Jurchens showed a side that was not afraid of death. Under the leadership of their officers, the soldiers of the Xicheng military camp used their flesh and blood to penetrate the blockade composed of heavy artillery to reach the east city wall, and continued to support the city wall in hand-to-hand combat with the Song army. In the end, they successfully drove away and eliminated the Song army in the city. At noon, Zhang Junming and Jin retreated their troops. Both sides counted their casualties. The Song army had a thousand casualties, while the Jurchens had more than 3,000 casualties, but they captured a dozen usable hand cannons. It wasn't that Zong Han was unlucky, but that Zhang Jun was stingy. There were only a few dozen people in the troops going up to the city carrying two cannons, so Zhang Jun ordered them to use up all of them. However, the Jurchens' fighting perseverance exceeded the Song army's expectations, and some of them were captured. "The inability to deploy the attack formation is the biggest weakness of our army." Zhang Jun said: "Unable to continuously support the city wall, it took 2,000 people a quarter of an hour to board the city." Wu Jie said: "Withdraw the water tanker. The convoy can be withdrawn, and it will take less than a quarter of an hour for 10,000 people to climb the city. But the Jurchens are defending the city wall unscrupulously. It is more difficult to attack than to climb to the sky. " Ouyang said: "The Jurchen troops in the north are being replenished one after another, and they have to be exhausted. It will take a lot of time for them to fight." "It can't be wasted. Although this kind of siege is advantageous, it will have a great impact on morale." Zhang Jun said: "The Jurchens' fighting will is beyond our expectations." "General. I have an idea." Wu Jie said: "Send more than a hundred warriors to sneak onto the city wall at night and use firearms to guard the four support channels. Ten thousand people will go to the city at night. "The support channel is the extension of the two cities and the lower city. Two stone stairs. "Well" Zhang Jun looked at the structure of the city wall and said: "It's not impossible, but if Zong Han guards the four exits, our army will not be able to break forward. There can only be three to five thousand people on the city wall at most, and then the Jurchen City will be in full formation. Aren't the forbidden troops on the city wall a target? The inside of the city is three or four feet higher than the outside. Zong Han's trump card is the archers hoarded in the north and south cities. They can line up in a few minutes and arrive within half a quarter of an hour to launch a projectile at the city wall. This trump card has not been used yet. It seems that although thousands of Song soldiers can climb the wall, only a dozen people can participate in the attack. Even if they have hand cannons, they can't throw the bow and arrow. After thinking about it, Chen Gui said. If only in half an hour?How about transporting forty heavy cannons up the city wall? " "Ah, of course that's good. Zhang Jun asked: "How to luck?" "If it is transported up, the Song army will be condescending. Since the three floors of the city wall are wide, the attack angle of the heavy artillery placed at the end is basically zero, and the shield soldiers can easily protect it. But unlike the original one, where the enemy is on top, the entire area is covered with straight arrows, which is accurate. The speed is quite high. And the most important thing is that the archers from Jurchen North and South City may not be able to use rockets and gunpowder arrows. But how to transport them? Chen Gui said: "This is a gadget designed by Xiaguan. "Chen Gui took out a few drawings. Ouyang leaned over and took a look. Isn't this the legendary fixed pulley or movable pulley? Ouyang's physics score is average, but he knows the existence of these two kinds of wheels. It is said that installing one wheel can save half the effort. Installing another wheel can save half the effort. Installing another wheel Zhang Jun obviously also has poor physics scores. Reading the drawings is like reading a book from heaven. Then he asked in disbelief: "Can this thing pull up a heavy artillery in half a moment?" " "Of course, as long as these points are taken care of, the following two people can pull the heavy artillery up. Zhang Jun pondered for a while and said: "Mr. Chen, the army has its own rules. If you want people, you can arrange them how you want." But the ugly words are ahead. I'm betting thousands of lives on this blueprint. If it doesn't go well, I must execute you to pay homage to the soldiers who died in battle. " "General, don't worry, I will issue a military order. However, I want to test it a few more times, train experienced hands, and transport the heavy artillery to the city wall as quickly and cost-effectively as possible. " Zhang Jun reminded: "The timer will start as soon as the heavy artillery crosses the moat. If the time is not met, I, the general, will engage in military law. " The length of the city wall, which is more than one mile, can be climbed up to hundreds of steps at the same time, and the forty steps are used for driving piles and fixed wheels. Although the overall city wall is strong, it is not too difficult to drill a few holes. And they are drilled on the brick surface. Just drill After making a hole, the wood was plugged into the extended part of the wheel, and nails were driven into the end of the wood to prevent the wheel from sliding. Then a rope was put on as required, and the rope was tied to the heavy cannon. The other end was pulled, and the big guy weighing more than 600 kilograms was pulled up. The people on the city then used ropes to pull the heavy cannon into the wall. Another option was to put wheels on the wall and pull the cannon up manually. Otherwise, the friction would be too great. It's not that heavy.
