Cao Zhang's letter was to be written to Jia Xu, who was assisting Zhong Xuan and Xiahou in Guanzhong to sweep away the princes of Guanzhong, Jia Xu was a native of Xiliang, and he naturally knew much more about the grievances and grievances between Han Sui, Bian Zhang, Beigong Boyu, and Li Wenhou than he Cao Zhang, so he wanted to ask if it was possible to say something like Li Wenhou and Bian Zhang's son Bian Jing. Pen, fun, pavilion www. biquge。 info

After all, they are not the biggest enemy for Cao Zhang, Cao Zhang's biggest enemy now is the Yang family who took advantage of the situation in Yizhou and the Sima family who have united Ma Teng and Han Sui, Yizhou and Liangzhou are bordered, when they are connected to the line, even if they are in danger, it is quite difficult to eat them, at this time, it is natural to unite all the forces that can be united, Li Wenhou and Bian Jing and Han Sui can be said to have a deep hatred, and they are more familiar with the situation of Han Sui and Liangzhou, the so-called knowing oneself and knowing the other, invincible in a hundred battles, Therefore, if you can say that these two people are defeated, you can get a little initiative in the battle with the Sima family.

After writing the letter, Cao Zhang immediately sent people to Guanzhong, and then personally went to his own guard camp to see Chen Dao, Chen Zhi this base commander on behalf of Cao Zhang to lead four thousand personal guard troops, after several battles have been partially reduced, and now the number has just been replenished, so Chen Zhi drilled the recruits day and night, and did not dare to slack off in the slightest, Cao Zhang met Chen Zhi in the tent on the edge of the camp colonel.

Cao Zhang said to Chen Zhi: "Uncle Zhi, the rainy season is about to pass, and we are about to send troops to the north to attack the remaining three counties of Pingyang County. ”

Chen Zhi said a little embarrassed when he heard this: "The last general was born with grass and didn't know much about the way to siege the city, but since following the third prince, I have read a lot of military books, and I know that the most important thing to storm the city is to have a flying ladder, but if the defending side has enough wooden rolling stones and arrows, the defense of the flying ladder is too poor, which will lead to a large number of deaths of sergeants. ”

Catapults and throwing machines are stone-throwing machines, because the launch frequency is slow, there is no accurate head, so only a large number of manufacturing, build hundreds of planes under the opponent's city and then launch at the same time, and smash the opponent's morale and city to a pulp, will get good results, only build so many for siege is a waste of manpower.

As for the siege car, it is to use a thick oak wood with a length of more than five meters and a diameter of more than 50 centimeters to soak it with oil to increase its toughness, and then create a huge fine iron awl about one meter five long and about fifty centimeters in diameter, which is inlaid on the treated oak wood as a chong cone, and then build a support with the chong cone as the center, there will be a spine-like giant wood above this support, and the chong cone is connected with ropes, and the outer end of the support is covered with raw cowhide soaked in oil, and the wheels and wheels are installed below. This is the structure of the siege car.

Usually the sergeant will hide under the raw cowhide to push the car to the city gate, and then shake the siege cone to break the city gate, the destructive power of the car to the city gate is very large, but the premise is to knock down the drawbridge above the opponent's moat, in order to attack the city gate, the reason why the ancient city has a moat, is to prevent the attack of the car.

The raw cowhide is slippery and tough, and the wood used in the bracket is a tough oak wood soaked in oil, so the blow of rolling stones, sassaga and arrows to the siege car is limited, if the drawbridge is knocked down, and the besieging party has a siege car, then it is a matter of time to break the city.

Chen Zhi can say that the catapult and the siege car rush car, it can be seen that he did hard work on the siege of the city, Cao Zhang's family history, and there are the world's wise strategists to give lectures to him, these affairs are naturally better than Chen Zhi, so he said: "Our people are limited, and we can't build a large number of catapults and throwing machines at once, so this method is not advisable, as for the siege car is a good choice, but whether it is raw cowhide, or used as a bracket and inlaid with iron awls, the giant wood must be of the highest quality, and it will take time to process before it can be made. Although we have a lot of people, it takes a lot of time for the blacksmith to build a siege awl, plus collecting and processing various materials, I am afraid that it is winter to make it, not to mention that the giant trees that make siege cones are not everywhere, not only if the old tree but also the torso is not bitten by insects, it may not be found for a while. ”

Chen Zhi said: "Other than that, the last general can't think of a better way. ”

Cao Chang was silent for a while and said: "Uncle Zhi, last time I asked Zhang Yan to attack the city, this time I can't call him again, otherwise it will make people think that I am weakening his strength, as for the tomb keepers are cavalry, it is not good for them to attack the city, and the method of forcing the villagers to attack the city is no longer available, so it seems that we can only send the people or our personal guards." ”

When Chen Zhi heard this, he immediately hugged his fists and said: "The last general is willing to be the pioneer of the siege!" ”

Cao Zhang nodded approvingly and said, "Uncle Zhi is indeed a great general, and I am also relieved to hand over the task of attacking the city to you, but should I send the people to attack or send the guards to attack?" ”

Chen Zhi said: "The attack of the people will only increase the casualties, and the morale will not be greatly damaged for a long time, it is better to let the pro-guard army attack, the salary of the pro-guard army of my Jinwu Temple is higher than that of the other eight battalions, and with the third prince to fight in Hebei for a long time, he is naturally willing to die for the third son." ”

Cao Zhang said: "My personal guard army only has 4,000 people, if the other party has enough materials to defend the city, I am afraid that I will not be able to take it if I don't attack desperately, so I decided to let Shu Zhi lead 2,000 people to attack the city, and the other 2,000 people will be led by me personally. ”

Chen Zhi was shocked when he heard this: "Absolutely not! The third prince is the commander of the three armies, how can he be lightly suspected? ”

Cao Zhang said: "It is precisely because the commander is in danger that the soldiers will use their lives, otherwise if you delay for a moment more, the coach will have one more moment of danger of death. ”

Chen Zhi said: "This... ”

Cao Zhang said: "Now our army in addition to my Jinwu Temple of the sergeant, there are also the Black Mountain Army, the tomb guard, the faction is clear, if I let any side to fight, and I sit in the army, they will inevitably move the mind of preserving strength, only I am in danger, they will take care of my safety will be killed, the three armies are not the same, the commander should fight to the death to encourage the sergeant, this is what the book of war says." ”

When Chen Zhi heard this, he knew that Cao Zhang was telling the truth, so he said: "Then I have to ask the third prince to take care!" ”

Cao Zhang said: "I only told Shu Zhi about this siege strategy, because if I say it in advance, I am afraid that my soldiers will oppose it, so I plan to talk about it when the soldiers are in the city, just to help Shu Zhi, so I will inform Shu Zhi first." ”

Chen Zhi arched his hand and said: "The last general knows!" ”

Cao Zhang said: "Okay, I plan to send troops on the eighth day of October, so let's get ready!" With that, he got up and left. (To be continued.) (To be continued.) )
