Unsuspecting, there were countless people among the defenders who were splashed with fire oil and burned, and this was when the trebuchets of the Flame Army outside the city were not calibrated, and there were only a few fire oil canisters that fell on the city wall, and most of them fell inside and outside the city wall.

There was a lot of screaming on the city wall, and as the oil canisters that fell on the city wall burned more and more, there were fewer places to stand on the city wall, and the temperature around them became higher and higher, and the defending sergeants who were not burned could not stay any longer, and ran down the city wall one after another.

In the midst of the Flame Army outside the city, Qin Feng sat on horseback and looked at the scene of the burning city wall, and couldn't help but say: "It seems that Captain Xi of our engineering battalion really has some ability, although this fire oil is a flammable thing, it is not easy to let it be sprinkled on the masonry and burn, how did he do it?" ”

Juniper next to him touched his short beard and said, "I do have some ability, and I don't know how long this oil can burn!" ”

"It is estimated that it will be extinguished after two moments, and the first battalion is ordered to prepare, carry the ladder in a group of two, and the two of them cover with a large shield, and wait for the siege order to be issued, run to the city wall with all their strength to set up the siege ladder first, and the rear team will quickly follow up with a round shield as a cover, and wait for the siege ladder to be erected on the city wall, and then climb!"

"The rest of the personnel are standing by under the city with shields as cover, and if the personnel on the siege ladder fall, someone must quickly replace them!"

"The archers followed the besiegers and pinned down the defenders on the city wall with bows and arrows, and when the defenders showed their heads, they immediately shot and killed the enemy archers!"

After a little thought, Juniper understood Qin Feng's arrangement, and immediately rode his horse to order the siege of the city.

It seems that after the end of this battle, it is not only necessary to continue to strengthen the military formation, but also to train the sergeants in siege warfare, siege warfare, which is a link that cannot be avoided no matter what, and if you want to expand your territory and seize the opponent's city, population and resources, siege is the most important link.

In all the military books of the entire Cold Weapon Era, there are almost no records about siege warfare tactics, and the most recorded is about the use of siege weapons, such as siege ladders, siege vehicles, catapults, well railings, bed crossbows, and so on.

But where the siege of the city, the soldiers of the besieging side are a mess under the city wall, there is no order at all, the defenders can kill and injure several people when they fall with a stone, pour a few barrels of oil down, and throw down torches to burn a large area.

In siege warfare, the use of siege equipment is undoubtedly a guarantee for the safety of the siege soldiers, no matter how strong the psychological quality of the sergeants is, it is impossible to send heads to the defenders in vain, and the reasonable and efficient use of siege equipment can protect the soldiers to the greatest extent, so that they will not collapse due to fear.

"It seems that after this battle, it is necessary to focus on training the sergeants in the siege of the city's tactical movements, coordinated combat ability and reasonable arrangement and control of the rhythm of the siege, and it is no wonder that in the siege war, as the side of the siege, the casualties are huge, messy, there is no reasonable and effective tactical tactics, there must be many casualties!"

Qin Feng completely regarded this attack on Yang'an City as a training for the soldiers in siege tactics and tactics, and did not seek to be able to capture Yang'an City in one go, but only regarded it as a training ground.

Next, he ordered the sergeants to carry out the siege in a fierce and orderly manner according to the way he had deployed, and personally taught the sergeants who were preparing for the siege the tactical movements of self-protection, the tactical movements and climbing rhythm when climbing the ladder, and how to use the time between the defenders to shoot arrows and drop stones and trees to climb up as fast as possible.

"Before attacking the city, find a rope to tie the round shield to the left forearm, if you are left-handed, tie the round shield to the right forearm, so that you can free up the hand holding the shield and grab the ladder to maintain the stability of the body, and you can hold a knife in your right hand, and you can fight with the defenders by rushing up the city wall!"

"There is another way, you can bite the blade with your mouth, hold a shield in one hand to protect yourself, and climb with your feet with the other!"

"If the defender above his head shoots arrows, he will definitely not be able to shoot them continuously, there must be a gap in the middle, so you must use this gap to climb up quickly, and you must put the shield on your head whenever you want to protect yourself to the greatest extent!"

"The sergeant on the side of the ladder under the city must not only protect the siege ladder from being pushed down by the defenders, but also try to protect himself, and the shield must always protect the top of his head, and there is only one person on a siege ladder from beginning to end, and one person must not climb up after one person climbs up, and if one person above is hit and falls, will not the one below also be smashed?"

"After the person on the siege ladder falls, the people cannot immediately lift and move him, after the other person continues to climb up, someone must go to protect the fallen person with a shield, check whether there is still salvation, if it is not cured, drag it away, if there is rescue, immediately carry it back on a stretcher to the medical officer for treatment!"

"Also remember that when rushing towards the city wall, you should use your shield to protect your body while running, if the defenders' arrows are too dense, you must quickly stop running and quickly crouch down and curl up in front of the shield in front of you, when you quickly reach the foot of the city wall, everyone must not gather together, you must spread out some, and scattering can minimize the hit rate of the defenders' arrow attacks!"

"It is necessary to check whether there are flammable materials arranged by the defenders at the foot of the city wall, and whether the flammable materials are sprinkled with fire oil, if the city is full of flammable materials and drenched with fire oil, our army will invest thousands of people to attack the city at one time, and as long as the enemy throws down the torches, will not the thousands of our troops be buried in the fire at the same time?"

"Also, during the siege of the city, if the enemy army spills a large amount of fire oil, you must quickly push away and get out of the range of fire oil to prevent the enemy from igniting and burning!"

The sergeants listened intently as Qin Feng taught them the secrets of self-protection and battle in siege tactics.

"Also, in the siege war, the archers have to play a role, they must follow behind the siege soldiers to contain the enemy by shooting arrows, and provide cover and support for our attacking soldiers to climb the stairs and jump up the city wall, and the arrows must not be fired indiscriminately and accidentally injure their comrades, therefore, the archers must be able to shoot accurately, and the enemy troops on the city wall are live targets, and you can only aim the arrows at the mouth of the wall, and only wait for the enemy soldiers to show their heads and bodies at the battlements, and immediately shoot arrows, and the moving target is not easy to shoot. Can't you shoot a fixed target? ”

The archers nodded frequently and aimed at the battlements, firing arrows whenever the enemy appeared at the battlements, and one or two were responsible for staring at the battlements so that the defenders did not dare to take the lead.

"As for how to make specific arrangements, this is arranged and decided by the chief, Dubo, and tun chief, and the task is assigned during the battle, which tun is responsible for that section of the city wall, and the task is assigned, there will be no omission or overlap!"
