Chapter 275: Fire Attack Yellow Dragon

The withdrawn Jurchen soldiers shivered and roasted the fire. Zong Han sighed when he saw it, it was originally good to kill and injure hundreds of enemies, but looking at the degree of frostbite of this group of soldiers, the situation was not optimistic.

"Haha! The generalissimo became a pickpocketed chicken. "A man passed through the sparse flowering bullets of the Song army, jumped off the horse and laughed at Zong Han, this is not someone else, but Wanyan Zongbi, who was demoted to the rank of captain and has a deep contradiction with Zong Han.

Zong Han waved his hand to stop the angry soldiers around him and said, "Wanyan Zongbi, you are not laughing at my Zong Han, but laughing at the Jurchen." ”

"Hah! Count me as a gaffe. Wanyan Zongbi asked, "How is it, Ouyang is poisonous enough, right?" As soon as he heard that Ouyang was in the prison army, he knew that this kid was going to be bad. But I didn't expect it to be bad like this. He didn't know that although Ouyang was bad, he couldn't think of such a professional way.

"Zhang Jun is not an idle person, it is almost impossible to destroy the waterwheel." Wanyan Zongbi said: "I have a plan to take revenge." ”

"What's the plan?"

"There was an ambulance army in front of the Song army, cavalry on the left and right, and heavy artillery was piled up in the middle. The formation is difficult to unfold. Wanyan Zongbi said: "So they can only send a thousand people at most to attack the city." ”

"What do you mean?"

Wanyan Zongbi smiled: "Let him attack!" ”

Zong Han was not stupid, and immediately understood: "You mean to let us shoot the Song army at the head of the city from the ancient tower?" ”

"That's right! The tower is more than 120 feet high, overlooking the city, without any obstruction. A hundred archers were stuck on the tower, and the Song army was like the prey of our hunt, with nowhere to hide. ”

"Good!" Zong Han said happily: "Then I will leave it to you to be responsible." ”

"Don't worry, I won't be as ashamed as you."

……

"Damn, there are hundreds of people gone." Zhang Jun slapped his thigh angrily after hearing the battle report. Two sieges and heavy losses. Although the losses of the Jurchens were not small, there were not a few people who froze to death or were blown up. But Zhang Jun knew that in the first confrontation, he made a few points entirely by relying on secret weapons, and he was the one who suffered a 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 is clear at a glance on the city wall. The Jurchens are good at shooting, and they can't stabilize the city at all. Moreover, the offensive path of our forbidden army is blocked, and it is difficult to transport a large number of troops at one time. ”

Wu Jue said: "But the last general, the Jurchens are also quite taboo about our army throwing water wheels. ”

"It's useless, the water truck can only *** to 200 steps, and then it can only be smashed on the wall." The stereotype 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." Command to collect explosives packs! ”

……

The Song army retreated in an orderly manner in the afternoon, and the two sides temporarily ceased fighting. After a night's work, the Song army began yesterday's tactics again. The charioteers, the cavalry swinged.

"Report!" Zong Han was drinking butter tea, and a personal soldier came to report: "Marshal, the Song army is digging a tunnel under the city. ”

"Digging tunnels?" Zong Han was shocked after thinking about it: "They are not digging tunnels. As soon as he finished speaking, a loud roar sounded.

Zong Han hurriedly went out, and a personal soldier intercepted him halfway and reported: "Marshal, the Song army is blowing up the city wall." ”

"I know!" Zong Han's face was ugly. He guessed what the Song army was going to do. When they abandoned the city wall, the Song army dug a hole under the city wall and blasted the wall. Not to mention that there are three layers of city walls, even if there are ten layers, it is not enough for the Song army to destroy. Ants gnaw on elephants and dig you out little by little.

"Oh, Generalissimo, you're going to peel it again." Wanyan Zongbi appeared.

"Are you waiting for someone to blow up a big mouth?"

"I mean, the generalissimo is not in a hurry for now. Anyway, they have to be peeled, so it's better to let them fry it for a while. ”

"What do you mean?"

"Once it has an effect, they will carry a large amount of gunpowder across the moat for continuous blasting. At this time, if you shoot again, the rocket will shoot a few arrows casually, and the Song army will be beaten with chickens and eggs, and they can also blow up their escort army. ”

……

Wu Jue said: "General, a small hole has been blown up, is it transporting a large amount of gunpowder?" A big blast on the gap? ”

Zhang Jun didn't answer and asked, "Master Ou, what do you think?" ”

"Judging from the abandonment of the city wall, the Jurchen commander is quite not simple." Ouyang said: "But five or six explosive packages have been blown up, and there is not even a single Jurchen on the wall, which is too weird." Ouyang guessed with the heart of a villain.

"Well, I think so too." Zhang Jun said: "General Wu, withdraw the people, don't be taken advantage of by others again, otherwise it will greatly damage morale." "Although there are few people, the feeling of failure is not small.

"Yes!" Wu Jue clenched his fists and left.

……

In the first two days, no one took advantage of anything. Zhang Jun still has time here, and he is not in a hurry. Zong Han was naturally not in a hurry. On the third day, the snow stopped and the sun rose, and the Song army temporarily stopped moving.

At the luncheon meeting, Zhang Jun had a meeting with several major generals and Ouyang. Zhang Jun said: "Now there are two ways. The first one, reducing the number of throwing trucks, allows me to deploy a siege army of at least 5,000 men per unit. But in this way, it will not be possible to suppress the enemy of the city wall, which is equivalent to a hard attack. The cavalry on both sides cannot be dismantled, otherwise in case of a counter-surprise attack, the front army will disrupt the rear army, which may cause a rout. The second method is to dismantle the heavy artillery, and 2,000 men are a unit to support the city wall. But without heavy artillery, the north of the city, which mainly hoards troops, can easily support the city wall, that is, hand-to-hand combat, we continue to transport, they send troops one after another, the city wall has become a decisive place, the losses will be very heavy, and once the attack cannot be stopped. ”

"The most annoying thing is the one hundred and thirty feet tall ancient tower." Ouyang asked, "Lord Chen, can the water cannon hit Gutana?" ”

"Barely so." Chen Gui smiled bitterly: "Your Excellency, do you want to flood the ancient tower? As far as I know, the ancient pagoda is very strong, and it is all made of solid bricks and bluestone. ”

"No, the tower is thirteen feet high, which is already very high." Zhang Jun jumped up after thinking about it and said, "Wu Jue." Collecting the oil of the fierce fire, we burned the ancient tower. ”

Ouyang was amazed by Zhang Jun's physics knowledge, and not every modern person knows that although bricks and other building materials cannot be melted in high temperatures, high temperatures can destroy their toughness and strength. Ouyang knew this principle because of the 911 incident. At the time, I wondered why the building had collapsed. Then I learned that the impact of the plane was not the cause of the collapse of the building, the main reason was that the fire burned and destroyed the toughness of the building materials, resulting in the building materials could not support the weight, and finally all collapsed, you must know that even modern bricks that are specially fireproof can only withstand temperatures of more than 1,500 degrees. But Zhang Jun could not have participated in the ...... of 911

"My father told me that the higher the brick kiln fire, the better, once it is too high, it will produce inferior bricks, and it will become powder when it is smashed." Zhang Jun said: "Let's return the ancient tower to the furnace again." ”

……

So the water fight was changed to a fire fight, and the materials were all ready-made, that is, the water was replaced with fierce fire oil. Eight hundred waterwheels suppressed the city walls, and two hundred trains attacked the ancient tower. Although most of the first batch of fire bombs were extinguished in flight, one or two personalities eventually broke out, and the fire at the bottom of the ancient tower inevitably burned.

When Zong Han heard the report, he couldn't understand Song Jun's intentions at first, and then under the reminder of the craftsman, he hurriedly ordered: "Put out the fire!" ”

The ancient records of fierce fire oil are also called water and stone paint. The period when the greatest role played in ancient Chinese warfare was the Five Dynasties and the Song, Jin, Liao, and Yuan dynasties, and it was during this period that oil was called fierce fire oil. The most mature use of fierce fire oil was in the Song Dynasty. The Song Dynasty set up an ordnance supervisor in the capital city of Bianliang, which was an institution specializing in the manufacture of weapons, with eleven works (i.e., workshops), including a special work of fierce fire oil. Fierce fire oil is generally used in defense, especially in the battle to defend a city.

Since there are no fire extinguishers such as carbon dioxide, water is poured on the oil, and the fire is even bigger. Zong Han was shocked, and the craftsman immediately said:

"Generalissimo, this is fierce fire oil, which cannot be extinguished by water, and can only be covered with sand."

Zong Han hurriedly shouted: "Dig the sand!" ”

However, as soon as the order was issued, the Song army expanded the scope of the attack, and in addition to the ten carts that continued to throw Meng Meng's fire oil at the position of the ancient tower, there were also twenty carts that began to set fire indiscriminately around the tower. The other cars stopped attacking, after all, the fierce fire oil was mainly a defensive battle, and Zhang Jun limited a certain understanding and did not bring too much.

The expansion of the area not only made the sandy soil strategy very effective, but Zong Han also had to consider the problem of fire prevention in the army. Several soldiers were burned to death by inaccurate fireshells.

"Report!" The Praetorian soldiers reported: "General, the fierce fire oil can only fire another 20 rounds. ”

Zhang Jun's expression did not fluctuate at all and ordered: "Let the ambulance army move, and the ten heavy artillery units will push forward and bombard the ancient tower." ”

Ouyang hurriedly said: "General Zhang, the Jurchen archer's head is very tight. Once the rocket was fired in the mouth of the heavy artillery, it detonated in a row, and our army suffered heavy losses. ”

"Quasi-head?" Zhang Jun said: "Don't worry, Lord Ou, the mountain people have their own clever plans." ”

The sound of 'boom' shells was heard, and several shells exploded in the fire, killing and wounding the soldiers who put out the fire. Zong Han shouted: "Order, the archer wall head defense." ”

Due to the watermill suppression, everyone can only strip naked for defense, but there is no need to worry about not igniting the fire. They also have some of the fierce fire oil used by Zhang Jun, and the Jurchen has a lot of gunpowder arrows, products eliminated by the Tokyo Shoji Bureau, and Zhang Jun's waterwheel is not a continuous heavy rain after all. The city wall is more than a mile long, and there are thousands of people on it, and as long as a few can shoot rockets, they may blow up the Song army. Condescendingly, the range of two hundred paces is still relatively simple for the Jurchens.

"Correction!" The lookout who climbed the ladder car immediately raised the signal flag and corrected the landing point of each gun.

After coming and going 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, but instead it was gray smoke. When I looked down, I saw in a haze that the ambulance army was burning dry manure and other smoke-emitting things.

Looking at the smokeless places on the left and right of the Song army, two ladders were raised to observe the artillery fire in the range, and the signal flag was used to correct the artillery fire. Wanyan Zongbi hurriedly said: "Generalissimo, let's go out of the cavalry." Two hundred steps, one breath away. ”

"Zhang Jun is a famous general, it is impossible to think of it. In case he had arranged it in advance, he would take advantage of the smoke to grab the city gate, and the consequences would be unimaginable. Zong Han reluctantly ordered: "Let everyone pay attention to the collapse of the ancient tower." ”

After about a quarter of a dozen bombardments, the ancient tower finally could not withstand the double blow and declared its collapse. Zong Han watched the ancient tower roar and fell to the ground and sighed deeply, the next battle was going to be even more brutal.

……

But the brutal battle came earlier than Zong Han imagined, and that night, the Song army was noisy and heavy artillery was fired. Zong Han led people to the city urgently in his sleep. But he didn't expect to be greeted by a ruthless water bomb. The deputy general asked: "Generalissimo, what to do?" To withdraw or not to withdraw? "If you withdraw, run quickly, and if you don't withdraw, you have to take off your clothes. In the past few days, he was tossed by the Song army's water bombs, and not many people died, but he fell ill a lot.

Suspicious? Positive attack? Zong Han looked at the dark night, and pondered for a while with Song Jun, who was busy boiling water and loading bombs in the distance: "Withdraw!" Order a team of 100 men to take turns to release arrows in the direction of 200 paces. "Everyone takes turns to go up and take a bath, once the Song army really attacks the city, it will inevitably cause death and screams.

Zong Han went down the city wall and walked around, his mood was heavy. Colds began to circulate in the army, and some soldiers also developed pneumonia, of course, at that time it was not called pneumonia, it was called pulmonary wind. It is a combination of pneumonia and measles. The lack of medical treatment and medicine is the biggest problem faced by Huanglong Mansion, and the most fatal thing is that the Song army has not yet launched a large-scale assault on Huanglong Mansion, but the combat effectiveness in Huanglong Mansion has decreased significantly.

The next day, Song Jun's water bomb started again, Zong Hanzhen didn't know how many ceramics Song Jun had fired, he didn't know, Ouyang used all the production capacity of the big factory under the name of the Chamber of Commerce, and it was produced for two months. Of course, Ouyang also has other ideas, this batch of imperial court orders can greatly alleviate the embarrassing situation of overstocking and no work in the factory. Objectively, it stimulated the economic recovery of the Great Song Dynasty. It is said that Zhao Yu saw the required expenses and scolded Ouyang and Chen Gui on the spot.

On this day, the Song army and the Jurchens fought for the city wall. The Jurchens all went into battle naked, because if they were not naked, they would be smashed by water bombs. Although after the Song army entered the city, the water bombs stopped attacking, but it was necessary to take into account that the Song army still had a sharp weapon to shake the hand cannon, and could not distance itself from the Song army.

The Jurchens showed their fearless side of death, and the soldiers of the Xicheng military camp, under the leadership of their own officers, used their flesh and blood to force through the *** line composed of heavy artillery to reach the east city wall, and continued to support the city wall and the Song army in hand-to-hand combat. In the end, he succeeded in driving out the Song army in Shangcheng. At noon, Zhang Junming Jin withdrew his troops, and the two sides counted the dead and wounded, the Song army suffered 1,000 casualties, while the Jurchens suffered more than 3,000 casualties, but more than a dozen hand-throwing cannons were captured. It's not that Zong Han is unlucky, it's that Zhang Jun is stingy, there are only a few dozen people in the Shangcheng army who carry two hand-throwing cannons, and the order Zhang Jun gave them is to use them all up. However, the Jurchen fighting perseverance surprised the Song army, and some were captured as a result.

"The inability to deploy the attack formation is the biggest weakness of our army." Zhang Jun said: "Unable to continue to support the city wall, it took 2,000 people a quarter of an hour to all ascend the city. ”

Wu Jue said: "If you remove the waterwheel, you can remove the ambulance army, and 10,000 people will arrive in the city in less than a quarter of an hour." But the Jurchens defended the city wall unscrupulously, and it was more difficult to attack it than to ascend to the sky. ”

Ouyang Dao: "The Jurchen soldiers in the north are being replenished one after another, and if they have to use up their soldiers, it will take a lot of time." ”

"It doesn't consume energy, although this kind of siege warfare is cheap, but it is a big blow to morale." Zhang Jun said: "The Jurchen's will to fight is beyond our expectations. ”

"I'll have an idea." Wu Jue said: "Send more than 100 warriors to sneak up on the city wall at night and use firearms to guard the four support channels. Ten thousand people went to the city at night. "The support passage is the extension of the two cities, and there are two stone stairs on the side and the lower city.

"En......" 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 through, and there can only be three or five thousand people on the city wall at most, and then the Jurchen City will shoot in unison, and the forbidden army on the city wall will not become a target?" The inside of the city is three or four feet higher than the outside of the city, and Zong Han's killer weapon is the archers hoarded in the north and south cities, who can line up in a few minutes, arrive in half an hour, and shoot at the city wall, this killer weapon has not been taken out yet. Although thousands of people in the Song army could go up to the wall, only a dozen people could participate in the attack. Even if there is a hand-throwing cannon, it can't throw the bow and arrow.

After thinking about it, Chen Gui said: "What if you can transport forty heavy cannons to the city wall in half an hour?" ”

"Ah, that's good." Zhang Jun asked, "How to get lucky?" "If it is transported up, the Song army is condescending, because the three layers of the city wall are wide, the angle of attack of the heavy artillery placed at the end is basically zero, and the shield soldiers can easily protect it. It's not like the original, the enemy is on top, the whole area is covered with straight arrows, and the accuracy is quite high. And most importantly, the archers who came out of the Jurchen cities in the north and south may not use rockets and gunpowder arrows. But how do you get it?

Chen Gui said: "This is a gadget designed by the lower officials." Chen Gui took out a few drawings.

Ouyang leaned over to look at Da Khan, isn't this the legendary fixed pulley or movable pulley? Ouyang has average physics grades, but he knows the existence of these two wheels. It is said that installing one wheel can save half the effort, and installing another wheel can save half the effort, and installing another wheel can save half the effort, and installing another wheel......

Zhang Jun obviously did not have good grades in physics, looking at the drawings was like reading a book from heaven, and then he couldn't believe it and asked: "This thing can pull up the heavy artillery in half a quarter?" ”

"Of course, as long as these points are right, the strength of the two people below can pull the heavy artillery up."

Zhang Jun pondered for a while and said: "Lord Chen, there are rules in the army, you can arrange it if you want people, and you can arrange it however you want." But the ugly words are ahead, I gambled with the lives of thousands of people on this drawing, and if it doesn't go well, I must correct you to pay tribute to the soldiers who died in battle. ”

"Don't worry, general, my military order is. However, I want to experiment a few more times, train skilled hands, and transport heavy artillery to the city wall as quickly and economically. ”

Zhang Jun reminded: "The heavy artillery will start to time when it crosses the moat, and if it is not overtime, the general will have to engage in military law." ”

The length of the city wall is more than one mile, and there can be hundreds of ladders at the same time, of which 40 ladders are used for piling and fixing the wheel. Although the overall wall is strong, it is not too difficult to make a few holes. And it's hit on the brick surface. It is to make a hole, and then the wood is tightly plugged and extended out of the part on the wheel, and the nail is killed at the end of the wood to prevent the wheel from sliding, and then the rope is put on according to the requirements, the rope is tied to the heavy gun, and the other end is pulled, and the big guy of more than 600 catties is pulled up. The people of the city then used ropes to pull the heavy cannon into the city wall. Another option is to put wheels on the wall and use manpower to pull the cannon up. Well, the wheels must be wanted, otherwise with friction, that guy will not be ordinary heavy.
