The last time the city of Nanjing was attacked was more than 1,000 years ago, when the Mon Kingdom had poured its troops into the city, but it was the first time that it had been besieged from all sides like today.

Unless they have an absolute advantage in magical power, it is a thankless task to rashly attack the state cities of other countries, because people can draw a large number of forbidden magicians and throw a few forbidden spells to the military camp at once, and the casualties are not ordinarily heavy.

This is also the reason why there are few magic towers in the state city, firstly, there is a portal that can be deployed at any time to support forces, secondly, to prevent the place from being difficult to control by the large imperial court, and thirdly, to save a lot of resources and allocate more resources to magicians.

Places like Pingzhong County City and Hengfu City can build magic towers at will, and as long as the imperial court blocks the surrounding areas, you will not be able to develop.

On the first day of siege, the siege was still far from the city walls, and long-range attacks could not reach it, and the attackers and defenders could only pour foul language on each other's heads, unable to deal real damage.

The biggest highlight was that the four divisions used different methods to clear the city defenses.

To the east, cold as a blade uses textbook tactics and earthwork.

First, the people dug a deep ditch behind the barracks, transported the earth to the front line, poured it on the ground, covered all the fortifications, whether they were traps or deer barricades, covered and compacted, and then advanced all the way.

It is characterized by the integration of attack and defense, which not only strengthens the defense of the rear of the barracks, but also paves the way for attacking the city wall, which is more labor-intensive and laborious, and is suitable for the use of troops with little siege experience and strong long-range attack.

Before the reinforcements arrived, the 111th Division had already laid a layer of earth steps, and except for the strong crossbow and crossbow cart troops, all the officers and men were engaged in carrying the soil, and even the cold blades were covered in mud.

To the south, under the supervision of the commander and chief of staff, Wang Chou sent a professional engineering team to carry out demolition and relocation.

The sappers dismantled the fortifications as they were, bypassing the most stubborn places and opening up a few passages for attack.

It is characterized by strong professionalism, less time-consuming, and easy post-war recovery, but it is easy to be targeted by the defenders, and is suitable for troops with strong combat effectiveness, rich experience, and a large number of engineers.

The 73rd Division borrowed the engineer corps of the 76th Division, a total of more than 2,000 people, and formed a line, and in one day's work it advanced to a distance of 500 paces from the city wall, and then it was about to enter the range of catapults.

To the west, Luo Tao began to attack, using the ploughing method.

The war horse dragged a professional iron plough, ploughed the ground, and then sent people to dig up the harmful substances, and then backfilled the soil, and when it came to a strong fortification, the bottom was dug up, and little by little forcibly pried open.

It is characterized by the fact that it can borrow the power of livestock and can invest more troops, but the organization is slightly cumbersome, it is easy to be injured when removing harmful substances, and the warning area is relatively large, so it is easy to be sneak attacked.

The 77th and 78th Divisions were old partners, they trusted each other enough to worry about vigilance, and their troops had enough experience and were very well organized, and the pace of advance was only a little slower than in the south.

To the north, Jomon attacked first and used mixed clearance.

This is like a teaching encyclopedia of siege and obstacle clearance, digging soil and burying ditches, demolition at fixed points, triggering traps with iron plows, etc., and all those in the army can be used.

The characteristics are that people and materials are used to the best of their ability, and the efficiency is relatively high, but the scene is chaotic and noisy, the warning surface is relatively large, and the commander spends more effort.

The 80th Division has all kinds of talents, and is good at urban offensive and defensive warfare, if it weren't for the magician being transferred, he would also use magic to clear obstacles, and the speed of advancement was about the same as that of the west.

Such a large-scale urban offensive and defensive battle is also rare in Shaodian's country, the key is that Shaodianxi castrated himself, there are too many fortifications outside the city, there is no place to deploy troops, and there are enough troops in the city but cannot prevent the counterattack.

Normally, it would take 200,000 troops to encircle a city with 100,000 defenders, with an average of about 40,000 or 50,000 on each side, to prevent the defenders from hitting one side of the attack. Like today's Nanjing City, the defenders could not get out, so Ding Kui would boldly adopt a four-sided attack, although he only had less than 100,000 troops at his disposal.

Ding Kui and Jiang Zhi had a clear division of labor, the commander was responsible for supervising the implementation of tactics, and the chief of staff was responsible for logistics support, and all their energy was focused on attacking the city of Nanjing.

"Don't rest at night, those two iron pulleys pull up and press the earth, here, here, here...... More pressure, the high platform should be built in a strong place, otherwise it is easy to be crushed by the trebuchet. Ding Kui reminded that the cold is like a blade.

"My lord, there are not enough manpower in the East Battalion, and it may not be able to catch up with the progress in other directions. The cold slapped the mud spots on his body vigorously.

Although the 112th Division had arrived, the 113th Division still had to go to Anyang County to escort a batch of materials, and 20,000 troops and 2,000 people were not enough to carry out earthwork work.

The amount of work to cover the fortifications is not too large, and in the middle of the year, it is necessary to build a high platform, which is really a lot of work, and the closer to the city wall, the longer the transportation distance, Han Rujian is worried that he will drag his feet.

"Well, tomorrow you can borrow the spare war horses of the 71st Division, and the 113th Division will come back the day after tomorrow. Ding Kui had to temporarily appropriate the war horse.

The 71st Division traced the traces of the Tenth Army Corps everywhere, but it always needed a temporary base for supplies, and the cities taken by Anyang County basically had no strategic materials, and they were all moved to the state capital, and the largest supply base was in the barracks outside Nanjing.

Dongda Camp has a super-large horse shed, which can accommodate tens of thousands of war horses, as well as sufficient forage, horse clothing, arrows and other materials, which is specially prepared for the 71st Division.

The cavalry division was routinely equipped with one man and three horses, and used one man and two horses for short-distance operations, leaving one horse at the base, so that there were 10,000 spare horses in the eastern camp, which could now be used to carry dirt.

Of course, these horses could also be used to plow fortifications, but the 12th Army Corps did not begin training in this subject, and the vast majority of officers and soldiers had not yet mastered this skill.

The 10th Army Corps cruised around the periphery, preferring the flattest place to attack, and Ding Kui predicted that the Dongda Battalion and the Beida Battalion were the most vulnerable to attack, especially the 12th Legion camp, which was slightly weaker in combat.

The longer and wider the deep ditch behind the eastern camp, the safer it is, and the appropriation of war horses to speed up the soil transportation can also speed up the progress of deep trench excavation, so the use of war horses can achieve the same tactical purpose.

On the second day of the siege, the 111th Division, after a morning's hard work, finally spread the earth to the edge of the trebuchet's attack on the city. Although the trebuchets on the other three walls had fired, Chill was still very happy with the result.

Wei Shiwen came to the quietest part of the city wall, and found that the enemy troops had stopped carrying dirt and had instead brought in rolls of hay.

"The enemy has entered the attack range, why don't the trebuchets attack?" Wei Shiwen asked the commander of Dongcheng.

The commander of Dongcheng hurriedly replied: "Now the attack can only hit those dry grass, and it will not hurt anyone, and the stone bullets will be wasted in vain, and I want to wait for the enemy to get closer before attacking." ”

"Nonsense! Pile up the hay again, can you see the person you meet later, attack me immediately!" Wei Shiwen was furious.

Now the east wind is blowing in the city of Nanjing, and the enemy army is moving out the hay rolls, and its intention is not to know, it must be a fire and smoke!

Boom, a boulder fell to the ground, rolled twice and fell into a pit, and Dai Le stood motionless behind the pit.

"Make up two rolls here. He pointed to the gap that had been smashed by the stone projectile.

Immediately, a soldier pushed over two rolls of straw to fill in the gap.

"Okay, now throw the rolls up, and fold them as high as possible. Dai Le took the place of Long Shuang's command.

Long Shuang walked over with two cloth bags on his face, looking like a bitter melon, and said, "This bird droppings are too smelly." ”

"Sprinkle it on the haystack, boss, bear with me for a while, and let the enemy smell it for a while. Dale pinched his nose and dodged away.

"Fall for your boy, give me this work. Long Shuang threw out two cloth bags in the air.

Uh-huh, uh-huh, there was an archer volley in the back that shot through the cloth bag, leaking out the guano inside.

Suddenly, Dai Le threw a sword bolt that shot through the haystack and accurately hit a stone projectile that had just landed.

"Here, put a horse here, put me on this haystack, how can the enemy's trebuchet like to smash it at me?" He was in a position more than four hundred steps from the city wall, and if the trebuchet shot a little more accurately, the stone projectile could fall directly on his head.

It was much easier to carry straw rolls than dirt, and the 112th Division was well rested today, so it was able to send more troops to help, and in less than an hour a wall of grass mixed with stones was piled up.

"Ignition!"

With the order of the cold blade, the haystack quickly ignited a raging fire,

Because the haystack was sprinkled with a lot of bird droppings, mixed with hay burned a lot of black smoke, a gust of east wind blew, and the smoke drifted towards the city wall.

The black smoke filled the area, and before the wall was covered, Wei Shiwen couldn't see the situation behind the fire clearly.

"Smash the fire, don't let the enemy burn it anymore. He hastened to order.

"Lord Wei, the stone bullet landing point is not so accurate, and besides, the enemy's speed of replenishing the grass roll is faster than ours, and the stock of stone bullets is limited. The commander of Dongcheng persuaded him bitterly.

As he said, the stone bullets were to supply the four city walls, mainly against the enemy's large siege equipment and dense battle formations, and it was a bit overkill to smash the haystacks.

At least it can slow down the progress of the enemy siege, and you don't need to think about the inventory of stone bullets. "Wei Shiwen basically saw the siege tactics in the east.

Behind the fire, thousands of war horses came up with mud bags, and Long Shuang returned to the command position, arranged for his subordinates to unload the mud bags, and then stacked them neatly behind the grass wall. Some soldiers pushed the scattered stone bullets together, poured mud on them, stacked mud bags around them, and built a dirt slope little by little.

"Hurry up, hurry up! Pile up the foundation of the high platform before dark!"

She planned to build seven earthen platforms, flush with the city walls, or even slightly higher, and set up bed crossbows and trebuchets on them. If all goes well, tomorrow her troops will be able to attack the defenders directly.

On the southern battlefield, Ma Ju replaced Wang Chou, and had already sent archers to cover the infantry to support the curtain, and began to build trebuchet positions, ready to shoot at the trebuchets on the city walls.

This is bullying people with a higher quality of individual soldiers.
